Abstract
The invention discloses a valve plate, which comprises a valve plate body, wherein the valve plate body is shaped into a regular hexagon; a through groove is formed in the middle position of the valve plate body; a plurality of through holes also are formed around the through groove respectively, and comprise first through holes, second through holes and third through holes; the first through holes are formed in the left and right sides of the valve plate body; the second through holes are formed in the upper and lower sides of the valve plate body; the third through holes are formed in the upper side of the valve plate body. The valve plate is molded at one time by powder metallurgy, the through groove is formed in the middle position of the valve plate body, and the through holes also are formed around the through groove respectively, so that the valve plate has the advantage of compact and firm structure, and can be completely attached to the sealing surface of a valve seat, a good sealing effect can be maintained, and the leakage of a medium can be minimized.
Description
Technical field
The present invention relates to the numerically-controlled machine tool rest field, particularly relate to a kind of valve plate.
Background technique
When the tradition gate valve is in the operating mode of high temperature or temperature alternating, in the situation that heat-treat technique or bear working load, valve plate and valve seat easily produce thermal expansion, distortion and creep.The valve seat shape is generally cylinder ring, in bulk temperature, approaches under the operating mode of medium temperature, and distortion is uniform.And valve plate is approximate rectangular, with the temperature of medium contact temperature partly higher than other parts of periphery, the temperature field skewness, produce inhomogeneous distortion, make valve seat and valve plate bad connection, sealing surface can not be fitted fully, thus cause that partially sealed specific pressure is excessive, sealing surface easily abrades, produce gap, to leak quantitative change large and do not reach the problem such as seal request, the accident such as initiating device shut-down even.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of valve plate, the valve plate body is equilateral Hexagon, adopt the powder metallurgy once-through, the neutral position of valve plate body arranges a groove, described groove surrounding also is respectively arranged with several through holes, compact structure, sound construction, and it can guarantee to fit fully with the sealing surface of valve seat, keep good sealing effect, be reduced to minimum by the dielectric leakage amount.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of valve plate is provided, comprise the valve plate body, described valve plate body is equilateral Hexagon, the neutral position of described valve plate body arranges a groove, described groove surrounding also is respectively arranged with several through holes, described through hole comprises the first through hole, the second through hole and third through-hole, described the first through hole is arranged on the left and right sides of valve plate body, described the second through hole is arranged on the both sides up and down of valve plate body, and described third through-hole is arranged on the upside of valve plate body.
In a preferred embodiment of the present invention, the thickness of described valve plate body is 1-1.5cm.
In a preferred embodiment of the present invention, the quantity of described the first through hole is 2, and the quantity of the second through hole is 4, and the quantity of third through-hole is 2.
In a preferred embodiment of the present invention, the diameter of described the first through hole is greater than the diameter of the second through hole, and the diameter of described the second through hole is greater than the diameter of third through-hole.
In a preferred embodiment of the present invention, described groove is that semicircle facing each other forms.
In a preferred embodiment of the present invention, the density of described valve plate body is 6.8-7.2g/cm.
The invention has the beneficial effects as follows: valve plate of the present invention, the valve plate body is equilateral Hexagon, adopt the powder metallurgy once-through, the neutral position of valve plate body arranges a groove, described groove surrounding also is respectively arranged with several through holes, has compact structure, well-set advantage, and it can guarantee to fit fully with the sealing surface of valve seat, keep good sealing effect, be reduced to minimum by the dielectric leakage amount.
The accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
