How to achieve the desired temperature? Adjusting the tap on the heating battery
The radiator tap allows you to control the flow of circulating coolant, including shutting it off in case of checking or flushing the batteries.
With the help of this device It is possible to turn off the radiators without pressure testing the main heating system.
The principle of temperature regulation of heating radiators
It is directly related to the design features of this element and its installation. The crane is a ball with a hole through it.
The operation of the tap is controlled by a handle fixed to the ball by a rod.
Important! For mounting the device it is necessary to choose the location wisely so that turning the handle in the future does not interfere with other devices of the heating system.
Tap and pipe diameter values must be identical.
The device must be fixed in parallel as it is twisted using tow or special tape. They provide the mechanism with additional protection against leaks. The correctness of the installation is then checked by applying water pressure.

The actuation of the handle facilitates the movement of the mechanism around its own axis. Rotation of the ball hole to the pipes and pipeline inlets makes it possible for the coolant to circulate through it, otherwise the fluid flow will be blocked.
The ball in such mechanisms can be fixed and movable. In the first case, it is attached to the rod so that it remains completely static. The tightness of such a connection is ensured by bolts or disc springs.
The movable ball is capable of moving depending on the degree of water pressure on itDue to this possibility, this type of mechanism is more widespread than the first.
How to open a tap
This is done to supply the maximum possible amount of coolant to provide the room with heat. To adjust the mechanism, it is necessary turn the handle parallel to its own axis and the pipe.
For convenience, there are protrusions on the tap body indicating the limits of its opening. This is done counterclockwise.
How to close
This action completely stops the circulation of the coolant. This is required when it is necessary to reduce the radiator temperature to a minimum, for example, in the summer.
The handle of the device is in the "off" position must form an angle of 90 degrees with its axis and pipeline. In accordance with the protrusions, the movement of the handle to stop the circulation of liquid must be performed clockwise.
Reference. In both situations, in the absence of a handle, it is possible to determine the position of the tap by recessIf it is aligned with the pipeline and the mechanism itself, then its position is “open”, otherwise the liquid flow is blocked.
How to turn a jammed tap on a radiator, adjust it
Often this situation occurs if periodically, as a preventive measure, do not change the position of the mechanism or develop it. Before taking any targeted actions to repair the device, It's worth trying to do it by hand.
Attention! It is necessary to know in advance what the crane is made of, since the use of additional mechanical tools may cause irreversible damage to the mechanism.
The renovation starts with unscrewing the locking nut and removing the handle. The top of the rod is located under the handle.
Some device models have hexagon socket clamp, which exerts pressure on the gland. If the rod is rotated only by applying force, then the bushing is fixed a little more freely.
At the same time, the formation of small streaks water at the top of the tap.
Then with using an adjustable wrench The rod is developed with slow movements from side to side.
Important! It is dangerous to apply increased efforts or to speed up the restoration work. This may lead to to the process of complete deformation of the ball or the mechanism as a whole.
The final stage of the repair process is installing the handle back. A trial rotation of it to the projections of the permitted degree of opening allows us to determine whether it is possible to fix the pressure sleeve. The final adjustment handle is installed in place only after a positive test result and checking the mechanism for leaks.
To avoid unpleasant consequences in the future in the form of a broken tap, do not use a device made of silumin, with the wall thickness of its pipes less than 2.8 mm. In this case, it is worth paying attention to high-quality products manufactured by European or Turkish manufacturers.

How to adjust correctly: useful information
Before you put it into operation, you need to make sure the sealing is done high-quality and reliable. This will help to avoid possible unpleasant moments, such as a failure or breakthrough of the system. The procedures for the direct use of cranes and their repair are simple, you just need to choose the right time, so that the water temperature is not too high. This is primarily due to certain safety measures and additional convenience of the working conditions.
