Pressure relief valve itself needs to withstand ultra-high pressure, is a safety valve, if the choice of substandard defective products, may lead to unpredictable losses. So it's good to be cautious when you choose!

How to select pressure reducing valve? The most important thing is to look at the structure

Piston structureValve advantages: 1, the whole forging, forming a safe, explosion-proof, 2, internal easy aging, high temperature resistant, long service life, generally more than 5 years; 3, can be equipped with pressure gauge;

Thin film structureValve: first of all, this kind of structure is eliminated, there are only some small imitation is still in production, disadvantages: 1, the valve body is composed of two pieces of copper with four screws assembled screw body more easily Water Leakage, high pressure interface easy to burst, 2, diaphragm valve mainly reduced pressure parts made of rubber this film is very easy to aging, the majority of customer reaction using 1-2 years of no effect, 3, cannot observe the pressure size, only Pingganjue to adjust the pressure.

Application of pressure reducing valve

A:Water pressure is too high and water hammer phenomenon is the most important reason for water bursting and leakage of water heater and water pipe of household water heater. Therefore, it is necessary to add a pressure reducing valve at the inlet to keep the water pressure constant. In this way, it is unnecessary to worry about the damage caused by high water pressure and water hammer to the household water equipment, and it is not necessary to cause other economic losses due to water leakage.

B: inlet water pressure is not stable, bath water temperature changes greatly, it will cause cold when the heat, you need to use pressure regulator valve.

     The pressure reducing valve is all brass,Piston type structure is adoptedThe internal structure is very simple, more durable, more environmental applicability, fine workmanship, reliable quality, durable. Without bypass pipe, piping is very simple, can save a lot of space and piping cost. It can be installed in front of any tap water equipment. The valve body with water inlet direction; the maximum pressure 1.6MPA, cover inner pressure regulating knob (six corners), according to their own need to adjust the different pressure of 0.1~0.8MPA. It can meet the requirements of decompression, especially suitable for the pipe pressure relief system.


technical specifications

1. nominal pressure: 1.6Mpa

2. working medium: water and gas

3. operating temperature: 0 degrees c

4. pipe thread meets: ISO0228 standard

5. outlet pressure: 0.1Mpa-0.5Mpa

The branch pressure reducing valve is mainly used in various building water supply system, fire fighting system and central air conditioning system,
Heating system, etc.. The utility model is used for reducing the pressure of the branch pipe, and the pressure distribution of the water supply is more balanced, and the part is avoided
Water supply point overpressure to optimize the water supply zoning of high rise buildings. It can replace the divisional frequency modulation variable speed pump,
In the fire water supply system can replace the district water pump, used for household water supply system, can protect all
Faucets and other water appliances. This type of valve should be installed horizontally in the pipeline.


Application of branch pressure reducing valve in high rise building:
When you have to install a pressure relief valve on a building, you have two options: Fig.A and Fig.B
Fig.A uses the dry pipe decompression, using a pressure reducing valve, when the floor is below 5 layers, you can use.
The disadvantage is that the water pressure of each floor is not the same, the price of a large caliber pressure reducing valve is higher. When floor
It can not be adopted when it is higher than 5 layers. Using a branch pressure reducing valve, each floor is using a pressure reducing valve, each layer of water pressure is 3.0bar.
The utility model is not only beneficial to the normal use of water, but also saves water, and the water supply pressure can be provided for the 26 storied building
The water only needs 1-21 layers to install the relief valve. The height of each floor is 3 meters, that is, every floor rises,
Water pressure drops 0.3bar) if the pressure of the main road is too high, you must reduce the water pressure first,
Then the branch pressure reducing valve is adopted.

2 matters needing attention

Matters needing attention in installation and maintenance of branch pressure reducing valve:
1, in order to facilitate operation and maintenance, the valve is generally installed upright in the horizontal pipeline.
2, the installation should pay attention to the flow direction of the medium in the pipeline and the valve on the arrow shown in the direction of the same.
3, in order to prevent the valve after pressure overpressure, should be at the outlet of the valve is not less than 4M installation of a pressure reducing valve.
