Abstract
The utility model discloses a valve plate which comprises a valve plate body. The valve plate body is in an equilateral hexagon shape, the middle position of the valve plate body is provided with a through groove, a plurality of through holes are further respectively arranged around the through groove and comprise first through holes, second through holes and third through holes, the first through holes are arranged in the left side and the right side of the valve plate body, the second through holes are arranged in the upper side and the lower side of the valve plate body, and the third through holes are arranged in the upper side of the valve plate body. The valve plate is formed in one time by powder metallurgy, the middle position of the valve plate body is provided with the through groove, the plurality of through holes are further respectively arranged around the through groove, and the valve plate has the advantages of being compact and firm in structure, can completely adhere to the sealing surface of a valve seat, have good sealing effect and reduce the medium leakage amount to the minimum.
Description
Technical field
The utility model relates to numerically-controlled machine tool rest field, particularly relates to a kind of valve plate.
Background technique
When tradition gate valve is in the operating mode of high temperature or temperature alternating, in the situation that heat-treating technique or bearing working load, valve plate and valve seat easily produce thermal expansion, distortion and creep.Valve seat shape is generally cylinder ring, approaches under the operating mode of medium temperature in bulk 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, temperature field skewness, produce inhomogeneous distortion, make valve seat and valve plate bad connection, sealing surface can not be fitted completely, 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 problems such as seal request, the accident such as initiating device shut-down even.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of valve plate, valve plate body is equilateral Hexagon, adopt powder metallurgy once-through, the neutral position of valve plate body arranges a groove, described groove surrounding is also respectively arranged with several through holes, compact structure, sound construction, and it can guarantee to fit completely with the sealing surface of valve seat, keep good sealing effect, dielectric leakage amount is reduced to minimum.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of valve plate is provided, comprise valve plate body, described valve plate body is equilateral Hexagon, the neutral position of described valve plate body arranges a groove, described groove surrounding is also respectively arranged with several through holes, described through hole comprises the first through hole, the second through hole and third through-hole, the first described through hole is arranged on the left and right sides of valve plate body, the second described 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 preferred embodiment of the utility model, the thickness of described valve plate body is 1-1.5cm.
In preferred embodiment of the utility model, the quantity of the first described through hole is 2, and the quantity of the second through hole is 4, and the quantity of third through-hole is 2.
In preferred embodiment of the utility model, the diameter of the first described through hole is greater than the diameter of the second through hole, and the diameter of the second described through hole is greater than the diameter of third through-hole.
In preferred embodiment of the utility model, described groove is that semicircle facing each other forms.
In preferred embodiment of the utility model, the density of described valve plate body is 6.8-7.2g/cm.
The beneficial effects of the utility model are: valve plate of the present utility model, valve plate body is equilateral Hexagon, adopt powder metallurgy once-through, the neutral position of valve plate body arranges a groove, described groove surrounding is also respectively arranged with several through holes, has compact structure, well-set advantage, and it can guarantee to fit completely with the sealing surface of valve seat, keep good sealing effect, dielectric leakage amount is reduced to minimum.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
