Description
Technical field
The invention belongs to valve technology fields, and in particular to a kind of jetting machine safety valve.
Background technology
Jetting machine is by power set high-pressure plunger pump to be made to generate high pressure water, and high pressure water is sprayed again by spray gun,
When the impact force of water is more than the adhesive force of dirt and body surface, the dirt of body surface can be washed away, so as to clean object
Body surface face.In order to ensure safety, jetting machine is required for installation safety valve, and existing safety valve is in jetting machine over pressure
It in use, cannot play a protective role to jetting machine and safety valve so that safety valve service life is short, replaces frequent, increasing
The big cost of cleaning.
The content of the invention
The technical problems to be solved by the invention are in view of the above shortcomings of the prior art, to provide a kind of jetting machine
With safety valve, which in use, can play a protective role to equipment and safety valve, extends in jetting machine over pressure
The service life of safety valve and repair, the maintenance times for reducing equipment.
The technical solution adopted in the present invention is：A kind of jetting machine safety valve, including safety valve body, safety valve
Set, safe spool and relief fittings, the safe spool and safe valve pocket are respectively positioned in safety valve body, one end of safe valve pocket with
Safe spool connection, the relief fittings are connected with one end that safe valve pocket connects with safety valve body, and the other end is located at safety valve
In vitro, the relief fittings is equipped with buffer stopper with safe valve pocket connectivity part, and the safe valve pocket one side is provided with relief hole, safety valve
Pressure release outlet pipe is equipped with relief hole corresponding position in vivo, pressure release outlet pipe one end is connected with relief hole, the other end and safety valve body
Outer connection, one side of the safety valve body away from relief fittings be equipped with elastic parts, the elastic parts include two spring bases,
Safety valve spring and spring pocket, the safety valve spring are sleeved between two spring bases, one of spring base and safety valve
Core is fixedly connected, and one side of another spring base away from safety valve spring is connected with adjusting screw, and the spring pocket is sleeved on bullet
Outside spring abutment and safety valve spring, the adjustment portion of adjusting screw stretches out spring pocket and is connected with adjusting nut.
Preferably, the adjusting screw is fixed by fixing nut and spring pocket.
The beneficial effects of the present invention are：
(1) by setting pressure release outlet pipe, in equipment over pressure in use, can by beyond pressure venting, it is effective to protect
Safety valve and equipment are protected；
(2) by setting elastic parts, when equipment uses pressure over-limit condition, safety valve can generate spring-like movement,
Convenient for remind in time user should not over pressure use equipment.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Embodiment
As shown in Figure 1, jetting machine provided in this embodiment safety valve includes safety valve body 1, safe valve pocket 2, peace
Full valve core 3 and relief fittings 4, the safe spool 3 and safe valve pocket 2 are respectively positioned in safety valve body 1, one end of safe valve pocket 2
It is connected with safe spool 3, the other end is connected with relief fittings 4, one end and peace that the relief fittings 4 is connected with safe valve pocket 2
Full valve body 1 connects, and the other end is located at outside safety valve body 1, and the relief fittings 4 is equipped with buffer stopper 5 with safe 2 connectivity part of valve pocket,
2 one side of safe valve pocket is provided with relief hole 6, and safety valve body 1 is interior to be equipped with pressure release outlet pipe 7 with 6 corresponding position of relief hole, and pressure release goes out
7 one end of water pipe is connected with relief hole 6, and the one side of the safety valve body 1 away from relief fittings 4 is equipped with elastic parts 8, the elasticity
Component 8 includes two spring bases 81, safety valve spring 82 and spring pocket 83, and the safety valve spring 82 is sleeved on two spring bases
Between 81, one of spring base 81 is fixedly connected with safe spool 3, another spring base 81 away from safety valve spring 82 one
Side is connected with adjusting screw 9, and the spring pocket 83 is sleeved on outside spring base 81 and safety valve spring 82, the adjusting screw 9
