Description
Technical field
It the utility model is related to check valve field, and in particular to a kind of high pressure check valve of adjustable Opening pressure
Background technology
Check valve, also known as check-valves or non-return valve, are that fluid can only be flowed along water inlet, water outlet medium can not but flow back
Device.Check valve has two kinds of through type and right-angle type, is usually mounted to horizontal pipeline, but can also be installed on vertical duct or
Tilt on pipeline, for preventing oil stream reverse flow in hydraulic system, or for preventing that compressed air is reverse in pneumatic system
Flowing.
And existing check valve is not easy to adjust when in use, and in use, adjusting bolt is mobile
During there may be rocking, and then influence the use of check valve.
Utility model content
Technical problem to be solved in the utility model is that existing check valve is not easy to adjust when in use, and is made
During, adjusting bolt there may be rocking, and then influences the use of check valve during movement, particularly in high temperature
In the environment of, the more bad control of check valve, can influence its leakproofness, and it is an object of the present invention to provide a kind of high temperature of adjustable Opening pressure
Check valve, solves the problems, such as that check valve uses.
The utility model is achieved through the following technical solutions：
A kind of high pressure check valve of adjustable Opening pressure, including connector, valve body, adjusting bolt, guiding screw pole, fastening
Part, the guiding screw pole are located in valve body, and guiding screw pole includes internal through hole, the limit convex being connected on guiding screw pole
Run through the passage of guiding screw pole by platform and through hole, the adjusting bolt is located in through hole, adjusting bolt in the guiding screw pole
Spring is connected with the both sides in front, the other end and the fastener of the spring connect, and the positive stop lug boss connects with valve body
Connect.
Further, this check valve in use, by adjusting adjusting bolt so that adjusting bolt forward compression bullet
Spring, the spring potential energy that adjusting bolt compression spring obtains is more, and the power of bigger is just needed when positive pressure sets and opens valve,
Therefore when controlling fluid one way flow, when positive pressure, which reaches, sets pressure, valve is opened, when buffer brake is higher than just
During to pressure, valve is closed, therefore this valve can effectively control to adjust check valve, and the tune of the present apparatus by adjusting bolt
Section bolt is placed in guiding screw pole, and the positive stop lug boss on guiding screw pole is connected with valve body, and then during use, is adjusted
Bolt will not cause double swerve in movement, and then cause the scattered of pressure, reduce the efficiency of power, and in the mistake rocked
It is broken that fatigue easily occurs in journey, shortens service life.
Specifically, a kind of high pressure check valve of adjustable Opening pressure, the fastener include seat retainer, valve seat and
The fastening thread that seat retainer and valve seat are connected, the seat retainer are connected with spring.The seat retainer is
Plastics PI materials, the valve seat are metal material.
Further, plastics can effectively improve precision to the sealing pair of metal and the use of adjustable springs, and
Using heat safe PI plastics, the high-temperature behavior of product both can guarantee that, and also more hold relative to the sealing of metal to metal
Easily.
Preferably, a kind of high pressure check valve of adjustable Opening pressure, the one end of the fastener away from adjusting bolt,
It is fillet in valve body (2) contact position, the fillet is smooth fillets.
Sealing of the small R angles to the conical surface, can further improve leakproofness, and use of the present apparatus without rubber parts, energy
Ensure the heat-resisting quantity of the present apparatus.
The utility model compared with prior art, has the following advantages and advantages：
1st, a kind of high pressure check valve of adjustable Opening pressure of the utility model, the present apparatus when in use, can be adjusted effectively
Opening pressure, is more convenient for using；
2nd, a kind of high pressure check valve of adjustable Opening pressure of the utility model, the present apparatus when in use, by will adjust
Bolt is placed in guiding screw pole, is further consolidated adjusting bolt, is prevented that during use, adjusting bolt, which is rocked, causes power
Scattered, not only efficiency is low, and service life is short；
3rd, a kind of high pressure check valve of adjustable Opening pressure of the utility model, the present apparatus is simple in structure, is easy to use.
