Description
Technical field
The present invention relates to a kind of valve body of valve, especially a kind of good airproof performance, it is strong to bear pressure, durable nonabradable
Valve body.
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.
The content of the invention
A kind of good airproof performance is provided the invention aims to overcome the deficiencies in the prior art, it is strong to bear pressure, durable
Nonabradable valve body.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of durable 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；Using circular conical surface transition connection size in the middle part of the step through-hole
Aperture.
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 present invention has following advantages compared with prior art：
A kind of durable valve body of the present invention program, good airproof performance bear that the pressure of medium is strong, and step through-hole uses circular conical surface
Transition connects, and step through-hole is not easy to wear, can increase the service life of valve body, reduces production cost.
Brief description of the drawings
Technical solution of the present invention is described further below in conjunction with the accompanying drawings：
Attached drawing 1 is a kind of schematic cross-sectional view of durable valve body of the present invention；
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；9th, circular conical surface.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
Attached drawing 1 is a kind of durable valve body of the present invention, 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 middle part of step through-hole 8 connects big aperture using 9 transition of circular conical surface
Footpath；The shrinkage pool 2 is in the inside of 4 position of shoulder；The angle of the 7 outer extended line of circular conical surface is 16 °；The oblique shoulder 6 with it is vertical
The angle in 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 step through-hole 8 is using circle
9 transition of the conical surface connects big small-bore, can be worn to avoid 8 stepped portions of step through-hole, extend the service life of valve body, leakproofness
Can be more preferable.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, it is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all cover within the scope of the present invention.
