Adjusting at the axial position of input adapter to realize sealing gasket, making internal thread I at described input adapter mider hole, described valve seat is connected with input adapter by internal thread I.
The beneficial effects of the utility model are:
1, reduction valve sets out water pressure controlling device, fixing pressure can be exported, also can meet the requirement that various watering equipment is different to pressure, regulate different outlet pressures, applied widely.
2, when input end pressure medium arranges pressure lower than reduction valve, valve is in maximum opening state, can not combined closure system.
3, pressure regulator is located at inside valve body, and utilize threaded adjusting outlet pressure, regulation precision is high, easy to use.
4, zone of high pressure good sealing effect, use safer, reliable, the life-span is long.
5, simple and compact for structure, component is few, volume is mutually little, fabricating cost is low, be convenient to promote the use of.
