On, the upper end of valve body 1 is bolted with and reaches in valve body 1, withstands on the disc spring pressure adjusting lever 13 of disc spring seat 12 upper end, rotates disc spring pressure
Power adjusting lever 13 can adjust the pressure to relief valve seat 6 for the disc spring 10.
The concrete structure that described delivery port 4 is provided with check-valves 5 is：Water out adapter 14, water outlet are bolted with delivery port 4
It is provided with poppet valve core 15, the tapering point of poppet valve core 15 is connected with delivery port 4 opening and closing, poppet valve core 15 and water out adapter in joint 14
It is provided with back-moving spring 16 between 14.
The lower end outside of described overflow valve element 9 is bolted with nut 17, and the overflow valve element 9 on the upside of nut 17 is provided with spacing
Ring 18, is provided with piston 19 between described nut 17 and spacing ring 18, the nut 17 between piston 19 and valve body 1 is set with multiple
Position spring 20.
The upside of described piston 19 is provided with stream control room 21, and the overflow valve element 9 between stream control room 21 and main valve chamber 2 is provided with
Lead core retainer plate 22 and Sealing shield ring 23, the downside of piston 19 is provided with pressure and pushes away room 24, and pressure pushes away room 24 and passes through in nut 17 and overflow valve

The back-moving spring 30 closing.
Described valve body 1 is split-type structural.
The specific work process of the present invention is as follows：
When the rifle valve of spray gun is opened, press water enters into from water inlet 3 and backs down poppet valve core 15 in main valve chamber 2 from delivery port
4 outflows, are connected with main valve chamber 2 because pressure pushes away the passage 25 passing through to arrange on nut 17 and overflow valve element 9 in room 24, so pressure
The pressure pushing away in room 24 is identical with the pressure in main valve chamber 2, passes through inner passage due to cone valve room 26 and connects with stream control room 21, institute
Identical with the pressure in stream control room 21 with the pressure in cone valve room 26, pressure pushes away room 24 and adds the nut between piston 19 and valve body 1
On 17, the back-moving spring 20 of suit overcomes the pressure of stream control room 21 and main valve chamber 2 up to push up piston 19, lead to overflow valve element 9 and
Relief valve seat 6 fits tightly, and makes press water in main valve chamber 2 pass through poppet valve core 15 and flows out it is impossible to from overflow from water out adapter 14
Overflow between valve element 9 and relief valve seat 6；In the course of the work when the hydraulic pressure in main valve chamber 2 is too high, press water backs down excessive spray gun
Stream valve seat 6 make to occur gap between relief valve seat and overflow valve element 9, press water from gap to overflow by backing down water stopping valve
Through hole 29 from the valve seat 11 that blocks water for the core 28 enters into backwater room 7, and the press water in backwater room 7 flows out from water return outlet 31, reaches
The purpose of decompression.
When the rifle valve of spray gun cuts out, press water enters in main valve chamber 2 from water inlet 3, now poppet valve core 15 and water outlet
Mouth 4 is in is close to state, and press water cannot be flowed out from water out adapter 14 by poppet valve core 15, leads to the pressure in main valve chamber 2 to increase
Back down greatly relief valve seat 6, make to produce larger gap between relief valve seat 6 and overflow valve element 9, the press water in main valve chamber 2 leads to
Cross gap to overflow, pressure water action overflow valve element 9 head overcome between piston 19 and valve body 1 nut 17 on be set with
The active force of back-moving spring 20 make piston 19 to bottom offset, now overflow valve element 6 and relief valve seat 9 fully open, main valve chamber 2
Interior press water enters into backwater room 9, backwater to overflow by backing down the through hole 19 from the valve seat 11 that blocks water for the valve element 28 that blocks water
Press water in room 9 flows out from water return outlet 31, makes valve body keep unloading condition.
It is made to move down by rotating disc spring pressure adjusting lever 13, disc spring 10 is shunk, the work to relief valve seat 6 for the disc spring 10
Firmly increase, now when have in main valve chamber 2 higher hydraulic pressure just can push relief valve seat 6 make press water from relief valve seat 6 with
Overflow in gap between overflow valve element 9, would not the situation of overflow in less hydraulic pressure；By rotating the adjustment of disc spring pressure
Bar 13 moves it up, and disc spring 10 is opened, and disc spring 10 reduces to the active force of relief valve seat 6, now has relatively in main valve chamber 2
Little hydraulic pressure also can push overflow the gap that relief valve seat 6 makes press water between relief valve seat 6 and overflow valve element 9.So
Make it move up or down the active force that can change to relief valve seat 6 by rotating disc spring pressure adjusting lever 13, play pressure regulation
Effect.
Above-described embodiment is only presently preferred embodiments of the present invention, not limits the scope of the invention according to this, therefore：All according to
