Technical Field
[0001] The utility model relates to the technical field of pressure reducing valve equipment, in particular to a branch pipe pressure reducing valve which occupies a small space. Background Art
[0002] The branch pipe pressure reducing valve is mainly used for branch pipe pressure reduction, which can make the water pressure distribution more balanced, avoid overpressure at some water supply points, and optimize the water supply zoning of high-rise buildings.

However, the current traditional pressure reducing valve does not have a filter, is large in size, and is inconvenient to install a filter mechanism due to structural limitations. To this end, we propose a branch pipe pressure reducing valve that occupies a small space. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] By installing the filter screen 5 at one end of the valve body 9, the filter mechanism can be integrated into the main body of the pressure reducing valve, which is compact and occupies less space, effectively improving the use effect of the pressure reducing valve mechanism and solving the problem that ordinary pressure reducing valves do not have a filter mechanism.
[0019] In the above solution, the valve flap 6 is mounted on the valve flap seat 7. The valve flap 6 has an adjustable positioning function to prevent the valve body shell wall from being penetrated.

[0021] In the above scheme, an O-ring 21 is installed under the piston sleeve 28. The main function of the O-ring is to provide excellent sealing performance. When the O-ring is placed in the sealing groove and subjected to pressure, it will deform and fill the sealing groove, thereby forming an effective seal. This sealing performance is crucial to prevent liquid, gas or dust leakage, especially in high pressure or high temperature environments. And O-rings are widely used in waterproof and dustproof applications. They can seal electronic equipment, mechanical parts and pipes to ensure that the equipment is not affected when operating in a humid or dusty environment.

[0023] In the above solution, a diaphragm pressure plate 12 is provided on the side of the bracket 14 .
[0024] In the above solution, a cap 19 is provided on the top of the valve cover 11 .
