Description
Technical field
This application involves a kind of progressive safety valves.
Background technique
In the prior art, safety valve is that opening and closing element is in normally off under by external force, when in equipment or pipeline
Pressure medium increases when being more than specified value, by outside system discharge medium come to prevent in pipeline or equipment pressure medium be more than rule
The Special valve of fixed number value.The compression of usual safety valve cannot change.
Summary of the invention
The application technical problems to be solved are to provide a kind of progressive safety valve.
In order to solve the above-mentioned technical problem, this application provides a kind of progressive safety valve, the safety valve includes one
Valve body with cylindrical valve chamber is provided with an overflow port on the side wall of valve body, and the bottom of the valve chamber opens up an oil-through hole,
Oil-through hole and valve chamber are coaxially disposed, and the internal diameter of oil-through hole is less than the internal diameter of valve chamber, and one is provided in valve chamber and was resisted against oil
Steel ball on hole, one end far from the oil-through hole of the valve chamber are provided with a pressure regulation spiral shell for running through the valve body
Thread, it is threaded with a locking nut on the voltage regulation screw, the locking nut is mutually fixedly connected with the valve body,
Be additionally provided with spring in the valve body, one end of the spring acts on the inner end of voltage regulation screw, the spring it is another
One end pushes against spring.
Preferably, circumferentially arranged on the inner wall of the valve chamber to have a circle concave ring, it is close to be provided with one in the concave ring
Seal ring.
Preferably, the locking nut and the valve body are integrally formed setting.
Preferably, the locking nut and the valve body weld.
A kind of progressive safety valve of the application, pressure fuel pump is excessively high and be arranged in order to prevent, when pressure oil superpressure, withstands
Steel ball, spring are compressed by pressure conduction, and steel ball position is moved at overflow hole, and pressure oil is flowed out from overflow hole, after pressure returns
Spring reset, the safety valve are equipped with voltage regulation screw, and the highest of adjustable super-pressure safety valve can be by pressure.

Specific embodiment
The application is described further in the following with reference to the drawings and specific embodiments, so that those skilled in the art can be with
It more fully understands the application and can be practiced, but illustrated embodiment is not as the restriction to the application.
As shown, the safety valve includes one with cylinder valve this application provides a kind of progressive safety valve
The valve body 1 of chamber is provided with an overflow port 11 on the side wall of valve body 1, and the bottom of the valve chamber opens up an oil-through hole 4, oil-through hole 4
It is coaxially disposed with valve chamber, and the internal diameter of oil-through hole 4 is less than the internal diameter of valve chamber, and one is provided in valve chamber and is resisted against on oil-through hole 4
Steel ball, the valve chamber far from the oil-through hole 4 one end be provided with one run through the valve body 1 voltage regulation screw 2,
A locking nut 3, the locking nut 3 and the fixed company of 1 phase of valve body are threaded on the voltage regulation screw 2
It connects, spring 6 is additionally provided in the valve body 1, one end of the spring 6 acts on the inner end of voltage regulation screw 2, the bullet
The other end of spring 6 pushes against spring 6.It is circumferentially arranged on the inner wall of the valve chamber to have a circle concave ring, setting in the concave ring
There is a sealing ring 7.
The locking nut 3 and the valve body 1 are integrally formed setting or the locking nut 3 and described
Valve body 1 welds.
A kind of progressive safety valve of the application, pressure fuel pump is excessively high and be arranged in order to prevent, when pressure oil superpressure, withstands
Steel ball 5, spring 6 are compressed by pressure conduction, and 5 position of steel ball is moved at overflow hole, and pressure oil is flowed out from overflow hole, and pressure returns
Spring 6 resets afterwards, which is equipped with voltage regulation screw 2, and the highest of adjustable super-pressure safety valve can be by pressure.
Embodiment described above is only the preferred embodiment lifted to absolutely prove the application, the protection model of the application
It encloses without being limited thereto.Those skilled in the art made equivalent substitute or transformation on the basis of the application, in the application
Protection scope within.The protection scope of the application is subject to claims.
