[Manifold valve uses]
Manifold valve mainly used in building water supply systems, fire systems, central air conditioning systems, heating systems. It is used to manifold vacuum, can a more balanced distribution of water pressure, prevent some water overpressure, optimize high-rise building water supply district. It can replace the partition FM gear pumps, fire water supply system in the district can replace the pump, for domestic water supply systems, to protect all the taps and other water appliances.
[Manifold valve Features]
1, direct acting membrane structure, the internal structure is very simple, without jamming, reliable performance and durability.
2, Dirt waterproof scale, without filter, without bypass pipe, the pipe is extremely simple and can save a lot of space and piping costs.
3, precision adjustable outlet pressure, in general case, can be considered unaffected by inlet pressure outlet pressure (the amount of change in the output pressure is 8% △ P1's).
4, excellent hydraulic characteristics, low pressure loss, reduction ratio can reach 10: 1 or more.
5, can meet a variety of decompression requirements, especially for manifold vacuum systems.
[Manifold valve works]
Manifold pressure relief valve outlet valve in the bottom surface and the bottom surface of the diaphragm, when it exceeds the spring setting, compression spring, so that the valve is closed. Just downstream of the dry flow, the outlet pressure will remain substantially at the set value (the variation of only 8% of the inlet pressure variation); When the downstream water pressure drop in exports, pushing the diaphragm spring, open valve. After a while a continuous flow of water, the relief valve opening generated from the damping effect, so that the opening and closing action stabilized.
[Manifold valve possible causes]
1, frost damage in cold areas should pay attention to insulation.
2, install the wrong direction of flow, pressure reducing valve becomes check valve, the outlet pressure to zero.
3, spring overtighten, can not be closed, the relief valve will straight P2 = P1.
4, the bypass pipe leakage, make P2 deviates from the set value, in view of the superior valve
Reliability and durability, it is recommended not to install the appropriate brightness through the tube.
