Description
Technical field
A kind of valve body of valve is the utility model is related to, especially a kind of good airproof performance, bears the strong valve body of pressure.
Background technology
Valve body is a main parts size in valve, mainly acts on water valve and air valve, for valve internal, there is barrier
Used in current or air-flow；There are different mechanical manufacturing methods, the valve body generally use casting of mesolow specification according to pressure rating
Make technique productions valve body；The valve body of mesohigh specification is produced using forging technology.Valve body and valve seat insert form close together
Pressure medium can effectively be born by being honored as a queen, so the leakproofness of valve body and bearing the size of pressure, determine the quality of valve.
Utility model content
The utility model aim is to provide a kind of valve body of valve for overcome the deficiencies in the prior art, especially a kind of
Good airproof performance, bears the strong valve body of pressure.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of valve body, including cylindrical body；It is described
The right-hand end of cylindrical body is provided with shrinkage pool；The shrinkage pool central part is provided with boss；It is outer in the middle part of the cylindrical body
It is provided circumferentially about to have shoulder；Set in the left side of the shoulder fluted；On the excircle of the left end of the cylindrical body
It is provided with oblique shoulder；Outer circumference surface is circular conical surface on the left of the oblique shoulder；Step is provided with the Left-side center of the cylindrical body
Through hole；The step through-hole left end diameter is more than right end diameter.
Preferably, the shrinkage pool is in the inside of shoulder position.
Preferably, the angle of the outer extended line of the circular conical surface is 16 °.
Preferably, the angle of the oblique shoulder and vertical direction is 17 °.
Preferably, the circumferential edges of the shrinkage pool are provided with chamfering.
Preferably, the angle of the groove is rounded corners.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
A kind of valve body of the utility model, good airproof performance bear that the pressure of medium is strong, can increase the use of valve body
In the service life, reduce production cost.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is a kind of schematic cross-sectional view of valve body of the utility model；
Wherein：1st, cylindrical body；2nd, shrinkage pool；3rd, boss；4th, shoulder；5th, groove；6th, oblique shoulder；7th, circular conical surface；8th, step leads to
Hole；.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Attached drawing 1 is a kind of valve body described in the utility model, including cylindrical body 1；The right-hand end of the cylindrical body 1
It is provided with shrinkage pool 2；2 central part of shrinkage pool is provided with boss 3；Platform is provided with the excircle at the middle part of cylindrical body 1
Shoulder 4；Fluted 5 are set in the left side of the shoulder 4；Oblique shoulder is provided with the excircle of the left end of the cylindrical body 1
6；It is circular conical surface 7 in the 6 left side outer circumference surface of oblique shoulder；Step through-hole 8 is provided with the Left-side center of the cylindrical body 1；
The 8 left end diameter of step through-hole is more than right end diameter；The shrinkage pool 2 is in the inside of 4 position of shoulder；7 extension of circular conical surface
The angle of long line is 16 °；The angle of the oblique shoulder 6 and vertical direction is 17 °；The circumferential edges of the shrinkage pool 2 are provided with chamfering；
The angle of the groove 5 is rounded corners.
The circular conical surface 7 and oblique shoulder 6 of this case valve body can reduce pressure of the medium to valve body well, and extend valve body uses the longevity
Life, sealing performance are more preferable.
It the above is only the concrete application example of the utility model, do not form any limit to the scope of protection of the utility model
System.All technical solutions formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
