Abstract
The utility model discloses a kind of metal relief valve, including valve body, spring, bonnet, slotting bolt and bonnet, one end of the valve body is connected with one end of the bonnet, and the spring is provided with it, one end of slotting bolt of the one end of the spring with being arranged in the bonnet is connected, and the other end of the bonnet is provided with the bonnet.The utility model provides a kind of metal relief valve, possesses reliable sealing, sensitive action, stable discharge in time, good to return seat performance and higher durable use；The utility model has the advantages that simple in construction, performance is stable and service life is longer.
Description
Technical field
The utility model is related to relief valve technical field, more particularly to a kind of metal relief valve.
Background technology
Relief valve also known as safety valve, according to the operating pressure energy automatic open close of system, are generally mounted to setting for closed system
Protection system safety on standby or pipeline.When exceeding relief valve setting in equipment or pipeline, that is, automatically turn on pressure release, it is ensured that equipment
With pipeline internal medium pressure under setting pressure, protection equipment and pipeline prevent accident.
Pressure-relief valve structure mainly has two major classes：Spring and lever.Spring refers to that bullet is leaned in the sealing of flap and valve seat
The active force of spring.Lever is the active force by lever and weight.Presently the most it is widely spring loaded safety valve, working condition
When, it provides sealing force by spring, it is ensured that equipment is normally run.When pressure rise, pressure medium overcomes spring force to make valve
Door is opened, and system pressure declines, and when pressure drops to certain value, valve returns seat under spring force.Typically lean on bolt
Screw rod adjustment work oil pressure air pressure etc..Shortcoming is as follows：
A, excessive entrance pressure drop can cause the chatter of valve, shorten valve service life；
After b, multiple chatter, the flatness of valve port and diaphragm is also resulted in, sealing property is influenceed；
C, reduced with the rise of pressure medium due to valve base sealing power, so can in advance leak-be set in not up to safety valve
Before fixed point, just there is a small amount of medium to spill.
Utility model content
The purpose of this utility model is that provides a kind of metal relief valve to solve the above problems.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The utility model includes valve body, spring, bonnet, slotting bolt and bonnet, one end of the valve body and the bonnet
One end connection, and be provided with the spring in it, one end of the spring and the slotting bolt that is arranged in the bonnet
One end is connected, and the other end of the bonnet is provided with the bonnet.
The utility model is preferred, and seal is provided between the inwall of the other end of the spring and the valve body.
The beneficial effects of the utility model are：
The utility model provides a kind of metal relief valve, possesses reliable sealing, sensitive action, in time stable row
Put, it is good to return seat performance and higher durable use；The utility model has simple in construction, performance stable and service life
Longer advantage.
Brief description of the drawings
Fig. 1 is a kind of structural representation of metal relief valve described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1：The utility model includes valve body 1, spring 3, bonnet 4, slotting bolt 5 and bonnet 6, the one of valve body 1
End is connected with one end of bonnet 3, and is provided with spring 3 in it, one end of spring 3 and the slotting bolt 5 that is arranged in bonnet 4
One end is connected, and the other end of bonnet 4 is provided with bonnet 6, seal is provided between the other end of spring 3 and the inwall of valve body 1
2。
Wherein slotting bolt 5 uses screw thread tightened-up structure, is engaged with bonnet 4, reaches the effect for adjusting different pressure release power
At fluting, convenient regulation pressure release power；Spring 3 uses carbon steel material, spring sizes is can adjust, to meet letting out for 0.3~0.8mpa
Pressure and the good time seat performance of guarantee；Bonnet 4 uses polytetrafluoroethylene (PTFE) material, with high-low temperature resistant, corrosion-resistant, gasproof
Wait, high lubrication the features such as, it is ensured that with body sealing valve port, and during multiple pressure release so that diaphragm and valve port are more beaten
More light, further ensures sealing and durable using effect；Metal body valve port is bright and clean, 1.6 roughness, it is ensured that with bonnet
Sealing；Φ 3mm pressure relief openings at metal body pressure relief opening 6, it is ensured that quick pressure releasing in a short time.
In summary, the utility model provides a kind of metal relief valve, possesses reliable sealing, sensitive action, in time
Stable discharge, it is good to return seat performance and higher durable use；The utility model have simple in construction, performance stable and
The longer advantage of service life.
Those skilled in the art do not depart from essence of the present utility model and spirit, can have various deformation scheme to realize this reality
With new, the preferable feasible embodiment of the utility model is the foregoing is only, not thereby limits to power of the present utility model
Sharp scope, the equivalent structure change that all utilization the utility model specifications and accompanying drawing content are made, is both contained in the utility model
Interest field within.
