Setting relief valve for water heater
The contents
Water heater or boiler is a device which is designed to heat water. As a rule, is operated by the consumer in the house or apartment. Water heaters have different constructive elements, but the traditional version is a metal container with internal heating elements, filled with water.
The principle of operation of the valve ↑
Safety valve for water heater is a brass base in which are mounted two spring locking elements. The first spring designed to provide the function of the check valve, i.e. not to let the water from the water heater back to the water supply system. The force of the water pressure in the water compresses the spring and the disc element opens the entrance for the water accumulated in the tank. Set an element inside the flow channel. If the water pressure in the water distribution system be reduced or disappeared altogether, the boiler will remain full.
The second spring is disposed on the challenge. Its main function – when you need to dump the water from the water heater. This action will prevent the rupture of the tank, in case of increased water pressure in the water system. How it happens: the pressure arising in the pipe system, pressure on the spring which is being compressed, opens the water inlet to brosnanu fitting.
Why the need for a safety valve for water heater? Safety valve in the design of the heater is an element that combines the functions which were essential to the safe and quality operation of the storage heater. This element aims to prevent high pressure in storage tank and to dump excess water, preventing the rupture of the heater. It also protects the integrity of the tank, which can be broken hydraulic shocks water network. Unfortunately, the powerful blows of water from the water pipes happen quite often. The valve prevents the water outlet from the tank when the water pressure decreases, or water is lost completely.
The types and characteristics ↑
Today, the market represents a wide range of safety elements. It is important to note that they differ in a variety of models and functionality.
For the Russian consumer the most appropriate were the valves of the following types:
- Safety valve for water heater. Performs the function of the protective element. Preserves the integrity of the reservoir in case of excess water.
- With the pressure adjustment. This element, depending on the situation, to reduce or increase the level of pressure in the water supply system.
- «Termeks». This product is of high quality and excellent technical characteristics. Ensures reliable operation of the storage water heaters.
- «Ariston». The products of the foreign manufacturer, which took quite a strong position in the domestic market. Safety valve for water heater «Ariston» features high quality performance and long service life.
- Brass model made of a very durable alloy. Durable and very strong alloy improves the reliability and duration of their operation. As a rule, brass safety valve for water heater 3 4, used for water heater gas type.
- « Algotherm». Highly durable items that can withstand sudden changes in pressure and temperature of the water flow in the water distribution system. Distinguished superior performance.
Purchasing a safety valve for the water heater, not be amiss to use the services of a consultant who will help to choose the appropriate option for a specific system boiler.
Professional advice on installing valve ↑
Valve must be mounted on the inlet line of cold water to a storage water heater in accordance with the following recommendations:
- in any case it is impossible to install isolation valves between the valve and the water heater;
- the hose from the valve is discharged into the sewer drain;
- to the discharge of water from the tank were faster, between the valve and the boiler mounted tee with ball valve.
With the installation of a safety valve on the water heater no problems and difficulties arise. The work is simple and the power of ordinary man, but in the case where the operation of the boiler is associated with an ongoing problem water leak, the consumer a lot of questions. Experts advise not to panic and to remember that the work of the boiler in which the valve periodically dripping water is normal. In order to fix the problem requires the installation of a special tube that lead the water into the sewer.
Special attention should be paid, if the pipe water is flowing continuously or on the contrary never drips. The situation in which the drops do not appear never, may indicate a failure. Experts advise in this case, the force to pull a little water from the tank by means of a special grip.
It is important to understand that the lack of a leak is not a sign of failure of the safety element. For an Autonomous system of water supply indicator water pressure does not exceed 3 Bar. So it creates a re-usable so rare that this fact can be easily overlooked.
Why relief valve water constantly flows? The reasons may be several:
- The failure of the safety valve. In this case, the only solution is complete replacement. It is not necessary to change it to a new element with a higher threshold. So you can completely disrupt the normal operation of the boiler, which will cause it to break.
- High water pressure in the water system of the house. A good solution would be to install a regulator at the entrance to the house, lowering the water pressure.
How to adjust the valve ↑
Initially, every element of the water heater is factory setting change that is unacceptable, and in some cases impossible. But there are safety elements that have the special adjustment screws, twisting or spinning that you can change the spring force, thereby adjusting the boundary of the operation.
The correct solution is to adjust the safety valve of the heater by selecting indicators of the certified values. An exception may be the adjustable device of the safety valve for water heater with scale. But as practice shows, the installation of this element is meaningless, because the maximum working pressure is constant.
Purchase and install only items of high quality, relevant technical requirements. Such models provide a long, safe and uninterrupted operation of the boiler.
Selection recommendations ↑
Typically, the electric boiler is already in the process of Assembly are equipped with safety valves. But there are times when you need more installation.
The main criterion for selection is the maximum permissible working pressure of the boiler. This figure is specified in passport data of the device.
The manufacturer offers consumers a wide range of safety valves with a pressure in the range of 6 to 10 Bar. Scale gradation occurs in increments of 0.5 Bar. This will allow you to play it safe and set it not lower than the maximum permissible limit prescribed in the passport of the boiler.
Experts advise to buy for the indirect boiler safety elements with the ability to adjust critical pressure.
Conclusion ↑
Safety valve is a very important Supplement for safe, uninterrupted operation of the water heater. It is important to purchase it in accordance with the technical specifications of the heating device. Personal improvement, as well as incorrectly selected valve may completely disrupt the work cycle of the boiler, and make it unsafe.
