Fig. 2 be in Fig. 1 A-A to sectional view.
Detailed description of the invention
The pressure adjustment relief valve provided the present invention with specific embodiment below in conjunction with the accompanying drawings is carried out in detail
Explanation.
As shown in Fig. 1 Fig. 2, the present invention provide pressure adjustment relief valve include valve body 1, small valve-rod 2,
Spring 3, valve pocket 4, overfall joint 5,6, two hands of taper knob are 7, butterfly spring 8 and big valve
Bar 9；Wherein the centre of valve body 1 has been formed through an axially extending bore 10, its underpart circumference
A water under high pressure import 11 and at least one being connected with water under high pressure outlet on pump head it is formed with on wall
Individual high-pressure water outlet 12, and water under high pressure import 11 is all connected with through hole 10 with high-pressure water outlet 12
Logical；The bottom of taper knob 6 is inserted in inside the upper port of through hole 10, its centre, lower surface
It is formed with a circular hole；Butterfly spring 8 is arranged on the inside of taper knob 6；Big valve rod 9 is nail shape structure,
Its head is arranged on butterfly spring 8 bottom in taper knob 6, and bar portion runs through the circular hole on taper knob 6 and prolongs
Reach the internal upper part of through hole 10；Two hands insert one end symmetry of 7 and are arranged on taper knob 6
Portion；One end of overfall joint 5 is inserted and is arranged on valve body 1 inside the lower port of through hole 10；
Valve pocket 4 is formed with the cylinder-like structure of opening for upper end, is located at the middle and lower part of through hole 10, wherein
The perforate corresponding with above-mentioned water under high pressure import 11 and high-pressure water outlet 12 it is formed with in portion's circumferential wall
13, lower circumference wall is formed multiple spout hole 14, and is positioned at perforate 13 and spout hole 14
Between position outer surface be fixed in overfall joint 5 upper inside surface；Small valve-rod 2 is nail shape
Structure, is located at the inside of through hole 10, and its head contacts with the lower end of big valve rod 9, and bar portion
Then it is arranged on middle and upper part in valve pocket 4；Spring 3 is enclosed within the head and the valve pocket 4 that are positioned at small valve-rod 2
On the bar portion outer surface of the small valve-rod 2 between end.
Described high-pressure water outlet 12 is 3, is separately positioned in the middle part of valve body 1 to enter with water under high pressure
Mouth 11, at a distance of 90 °, 180 °, the position of 270 °, can arbitrarily select one according to installation site
Use.
On described taper knob 6 lower outer circumferential face and through hole 10 top inner peripheral surface, valve pocket 4
Inner peripheral surface, valve pocket 4 middle and lower part outer circumference surface and overfall in the middle part of portion's outer circumference surface and through hole 10

Now the pressure adjustment relief valve using method that the present invention provides is described below: first by staff
Utilizing while observing the Pressure gauge being connected with pressure adjustment relief valve, rotation hand is rotary handle 7
The mode of set 6 regulates position in valve pocket 4, small valve-rod 2 lower end, until making to go out from water under high pressure
Till the water under high pressures that mouth 12 is discharged reach required use pressure, at this moment the lower end of small valve-rod 2 is proper
Block well and on valve pocket 4, be positioned at the upper port below perforate 13.Under normal circumstances, from fluid end
The water under high pressure discharged in cylinder body will be flowed on this pressure adjustment relief valve by water under high pressure outlet on pump head
Water under high pressure import 11 in, then relative with water under high pressure import 11 from valve pocket 4 perforate 13
Enter in the annular space between valve pocket 4 and small valve-rod 2, afterwards by valve pocket 4 with water under high pressure
Export 12 corresponding perforates 13 and flow into high-pressure water outlet 12, finally by with high-pressure water outlet
12 pipelines being connected are supplied to receive container for user.When the height discharged in fluid end cylinder body
During setting-out hypertonia, the water under high pressure entered in valve pocket 4 will press upwards on small valve-rod 2, thus press
Contracting butterfly spring 8, the lower end of small valve-rod 2 thus can be made to leave on valve pocket 4 be positioned at below perforate 13 is upper
Port, at this moment partial high pressure water will flow in overfall joint 5 from spout hole 14, finally from overflowing
Head piece joint 5 drains in overflow vessel, thus reaches the purpose of pressure release.When pressure recovers normal,
Small valve-rod 2 can rely on the elastic force of butterfly spring 8 to automatically reset.
