bypass system: what kind of device

bypass - ata bypass pipe that works as a dam and is equipped with an adjustable shut-off valve. Install the device on a gas pipeline, a water supply system, a heating system, a machine, electrical appliances.

In the heating system, the bypass is mounted between the forward and reverse travel near the battery. This device allows to regulate the coolant inlet to the battery.

With normal circulation of the system, the jumper freely flows fluid flows through itself. If necessary, disconnect one of the radiators, the element is closed, and the water goes around a certain length of the system.

The bypass system has many advantages bypass system has many advantages

device Advantages:

  • Simplifies circuit service;
  • Saves energy;
  • Warns of pipetting;
  • Allows you to carry out repairs during an accident in the system.

The bypass is manufactured with mechanical and automatic control. In the first case, closing and opening the valve occurs manually. The automatic bypass operates in autonomous mode. This model is used when installing a circular pump. When the unit is turned on, the bypass valve opens under the pressure of water. When the pump is turned off, it closes automatically. Bypasses are divided into radiator and pump. Radiator mounts on the way to the battery. They serve to disconnect the elements of the circuit. The second option is used to change the mode or disconnect the pump and mount it together.

Mandatory bypass in the heating system: what is it?

The bypass in the heating system is a mandatory component of the design. The element is mounted between the inlet pipe and the return pipe. The device solves the problem of a uniform distribution of the coolant in low-rise buildings.

The bypass in the heating system performs several functions bypass otpitelnoy system performs several functions

Assignment Bypass:

  • Return of excess water when the pressure in the riser;
  • In case of switching off the artificial circulation, the system transition to the natural movement of water;
  • Acceleration of the process of dumping and filling the system with a coolant;
  • Repair of heating elements without centralized shutdown;
  • Adjustment of the microclimate in the room.

With a single-pipe system, hot water, passing through the first radiator, rushes to the next heating element. With each subsequent entry, the coolant becomes colder. The last radiator receives the lowest temperature, thus not effectively using the efficiency. The bypass partially solves this problem. Thanks to him, part of the coolant goes around the first radiator, delivering hot water to the next battery.

Why use a bypass in the heating system of a private house and residential complexes

In a two-pipe system, a bypass is necessary to direct the heating source to other radiators. By means of the jumper it is possible to regulate the microclimate of the private house, leaving the necessary heat in the required rooms.

With the help of a bypass it is possible to control the microclimate of a private house With the bypass can be controlled microclimate private house

Nuances:

  1. If the electric pump is switched off, the heating will stop.
  2. Bypass can save a difficult situation.
  3. By closing the pump cock and running the coolant through the jumper, you can activate the natural circulation without stopping the heating system.

If there was an emergency leak in the radiator, you just need to close the cranes on the jumper. Water will bypass the system and it will be possible to dismantle the contour element without complications and replace it. Often the weather conditions are presented with surprises. In the autumn and spring period, the pipeline delivers an excessive amount of heat. In this case, you can close the node, stopping the access of hot water to the radiators, adjusting the comfortable conditions in the room.

The need for the bypass circulation pump

circulation pump is able to improve the heating system even with natural circulation. In the process of its installation, it is necessary to have a bypass. The circulating pump, although it increases the efficiency of heating, but makes it dependent on electricity.

necessity device for circulation pump:

  • Adjusting the heating performance;
  • Disconnection from the pump operating circuit;
  • Repair of the circulation unit without shutdown from autonomous heating;
  • Prevention

idle mode When a power failure, it prevents natural circulation of hot streams. The bypass solves this problem. Overlapping the jumper, physical movement of the fluid in the circuit occurs. When heated, the water rises upward and flows naturally along the contour, delivering the coolant to the heating elements. Cooling, descending and flowing in the opposite direction to the boiler.

To adjust the capacity of the circulation pump, it is necessary to set the bypass To adjust the performance of the circulation pump, it is necessary to install the bypass

When filling of the heating system, the pump and prevents the descent of the water storage, whereby air pockets are formed.

Bypass will help to completely get rid of this problem. Modern models bypass are equipped with an automatic valve. Such designs are indispensable for a system with a turbo-pump. With the head of water, its opening takes place, and the coolant moves without obstructions along the contour.

principle of operation of the bypass valve

If the unusual situation has occurred, a power failure or pump failure, the pressure ceases and the valve closes automatically jumper, blowing water by natural course. This allows you to fully automate the heating system. The lack of an automatic bypass is sensitivity to the variability of water and small contaminants. Before installation, it is recommended to clean the water line of the ATS to remove deposits and rust in pipes and radiators.

The bypass for the pump is a continuation of the return pipe leading from the radiator to the boiler. In parallel, it installs a pump on the branch pipes.

Before starting work, it is necessary to determine the material of the water supply system. For polypropylene pipes, dismountable connections are used, and first the pump unit together with the bypass is assembled. The branch is connected by means of tees mounted in the main pipe. When steel version, first solder the nozzles, then the valve on the bypass. The bypass system is installed towards the heat carrier and must be assembled in a certain sequence.

Assembly diagram:

  • Filter;
  • Check valve;
  • Pump forced action.

The diameter of the bypass line must be equal to the return diameter. Specialists recommend that when assembling all the cranes should be equipped with collapsible fittings. In this case, during repair, various situations will be eliminated.

How the bypass valve works The principle of operation of the bypass valve

Before starting the installation work on the installation of the pump, it is necessary to pull the coolant from the system. The entire structure is oriented so that the outlet pipelines are vertical or horizontal, depending on the stroke of the pipe.

How the bypass line works:

  • Collect a section of the bypass, which will be located parallel to the highway;
  • From the reverse cut off a section equal to the length of the bypass;
  • On the ends of the trunk set tees;
  • A section with a stop valve or valve is installed between them;
  • Connect the assembled section of the bypass to the main pipe with equal length.

During installation, it is necessary to leave space for the possibility of later dismantling the pump and other components. It is necessary to make the correct installation, following the coincidence of the arrow on the body with the coolant current.

Installation by yourself of the bypass line

Installation of the bypass in the heating system is easy, several rules must be observed. First, the diameter of the device should be less than that of the pipes in the heating. If you do not comply with this rule, the coolant will bypass the battery. Secondly, the bypass is moved as close as possible to the radiator. To install the jumper, the contour must be emptied. Next, the assembly takes place in the direction of the coolant.

Steps of operation of the bypass line:

  • The radiator is removed;
  • The bypass is connected to the mounting points;
  • Further on the edges is installed a stop valve;
  • Batteries are attached to new places.

Installation of the bypass line can be done manually You can install bypass lines

You can embed a self-made construction in the same way. Installation bypass is easy to do by yourself, without resorting to the services of expensive specialists. The main thing is to know a few subtleties. The jumper is installed as close as possible to the heater. The diameter of the device should be slightly less than the contour pipes. The shut-off valve is installed between the jumper and the radiator. Instead of ball valves, it is possible to install thermostats, which will independently direct the flows through the bypass when the required temperature is reached. When installing the device near the boiler, it is necessary to monitor the temperature to prevent overheating. Do not put a valve or valve on the valveless device. When cutting pipes, install tees.
