The valve is reverse for heating. Its purpose, choice and installation

The reverse valve for heating plays an important role during the operation of the system for heating the room. This design preserves the flow direction of the coolant flow. Specialists must necessarily perform the installation of the reinforcement in order to securely fix all connections.

The purpose of the valves for the heating system

When the heating season comes in, a constant hydrodynamic pressure arises in the system, which is localized at specific sites. The consequences of this phenomenon can be varied, and in some cases the main flow of the liquid is redirected. If a person has taken care of his home and installed a reverse valve for heating in a centralized system, he will not face unpleasant consequences. The presented design allows to achieve stable and trouble-free operation of the whole complex.

A non-return valve is able to prevent the heat carrier from moving back. That's why you need to carefully choose it for further installation. Today there are several varieties of these designs: petal, spring, disk, ball and reverse gravity valve for heating.

What are the causes of accidents in the heating system?

No one is immune from emergencies, which can occur for a variety of reasons:

• Water, which moves along the gravitational heating system, cools unevenly. The temperature expanding the liquid in the return pipes can reach the limiting value, and then the main water flow changes.
• Breakthrough and system failure can occur due to the installation of several heating circuits. It becomes more difficult to provide uniform pressure values inside each valve. In this case, the hot liquid can move in the direction of the lowest resistance values.
• Completion of the heating system. Intermediate mains and return pipelines should be installed. They perform the tasks of uniform distribution of thermal energy for each individual radiator.

It is for this reason that the return valve for heating must ensure the uninterrupted passage of hot water, and also prevent its reverse movement through the system.

How to choose the right valve?

Before buying parts for the heating system, you need to determine the main parameters for connecting them to the central pipeline. The main rule is full compliance with the through diameter of the reinforcement along the entire highway. For example, if the cross-section of the pipe is 35 millimeters, then the same value of the parameter should also be present in the non-return valve.

Next, determine the optimal type of connection of the structure to the system. Now every person will be able to come to the store and see a large selection of equipment for the heating system. There are several basic designs:

• The coupling valve has a thread with a connecting unit. This scheme is widely used for spring disk structures, which are installed in an autonomous heating system.
• Flanged models. They are intended for further installation on the highway, which have a large diameter. In most cases, the reverse valve is used for heating with a ball.
• Wafer type systems. They must be installed between pipes that are small in size and size. The optimum option for installation is flap check valves for centralized heating.

Features of the installation

During the installation of independent heating, where there will be a non-return valve, several important steps must be taken into account:

• The housing must include devices for guiding the movement of hot water.
• To significantly improve the waterproofing, you need to use specially designed gaskets from paronite. For this purpose, winding is also suitable. Materials should not reduce the area of the working section of the stop valves.

The check valve for the heating system is made of stainless steel or brass. It must be installed at every point where there is a branch of the pipeline.
