Description
Technical field
The present invention is a kind of valve that is used under the High Temperature High Pressure occasion, particularly a kind of Wedge type abrasion resistant plug valve.
Background technique
Existing stopcock seals with direct contact the between valve body by accurately machined metal cock body, so sealing is relatively poor, hoisting capacity is big, and wearing and tearing can only be used for low pressure (not being higher than 1 MPa) and temperature usually and be not more than 325 ℃ occasion easily.
Summary of the invention
The objective of the invention is in order to overcome the defective that existing stopcock sealing is poor, hoisting capacity big, wear and tear easily, inventing a kind of sealing pair is cobalt chromium tungsten cemented carbide, all sealable Wedge type abrasion resistant plug valve of valve seat both sides sealing face.
The objective of the invention is to realize as follows:
Described Wedge type abrasion resistant plug valve comprises bottom, valve body, cock body, valve rod, valve gap, top cover, handle and handwheel;
The bottom of valve body is provided with bottom, and the top of valve body is provided with top cover, is provided with cock body and valve gap in the valve body;
One horizontal through hole is arranged on the cock body, and the bottom of cock body is located in the bottom, and cock body and valve body constitute the cone angle sealing pair, the top of cock body is provided with axle sleeve, axle sleeve is located at the bottom of valve gap, and cock body can rotate in bottom and axle sleeve, and the rotation of cock body will constitute the open and close of stopcock;
Valve gap is bearing in the upper end-hole of valve body by support plate, and opens cup by seal ring and four and seal mutually with valve body;
Valve rod is located at the top of cock body, and valve rod passes axle sleeve, valve gap and top cover and stretches out outside at top cover; Valve rod seals with valve gap mutually by filler, filler gland, hold-down grid, and handwheel is screwed onto the top of valve rod by Stem Mut, bearing and stop screw, and the rotation of handwheel will drive cock body by valve rod and move up and down; The middle part of valve rod is provided with handle, and the rotation of handle can drive cock body by valve rod and rotate synchronously.
The cone angle sealing pair that described cock body and valve body constitute, the sealing pair is convex shape, makes cock body and valve body form the sealing of wedging power.
Described valve gap and support plate are connected in one by bolt.
The material of described cone angle sealing pair is a cobalt chromium tungsten cemented carbide.
Good effect of the present invention is as follows: because in the opening-closing process of valve, cock body and valve body are the state that is separated, so the keying of valve is very light; And sealing surface is opening or close difficult scratch in the closed procedure, so the valve long service life; Because sealing pair is a cobalt chromium tungsten cemented carbide, so have good wear-resisting, heat-resisting, corrosion-resistant and antisticking polishing machine, in the time of 800 ℃, still keeps superperformance; Characteristics such as the present invention has compact structure, volume is little, fluid resistance is little, operation is light, high temperature resistant, long service life.

Embodiment
As shown in Figure 1, described Wedge type abrasion resistant plug valve comprises bottom 1, valve body 2, cock body 3, valve rod 4, valve gap 6, top cover 10, handle 14 and handwheel 17;
The bottom of valve body 2 is provided with bottom 1, and the top of valve body 2 is provided with top cover 10, is provided with cock body 3 and valve gap 6 in the valve body 2;
One horizontal through hole 19 is arranged on the cock body 3, and the bottom of cock body 3 is located in the bottom 1, and cock body 3 constitutes the cone angle sealing pair with valve body 2, the top of cock body 3 is provided with axle sleeve 5, axle sleeve 5 is located at the bottom of valve gap 6, and cock body 3 can rotate in bottom 1 and axle sleeve 5, and the rotation of cock body 3 will constitute the open and close of stopcock;
Valve rod 4 is located at the top of cock body 3, and valve rod 4 passes axle sleeve 5, valve gap 6 and top cover 10 and stretches out outside at top cover 10; Valve rod 4 seals with valve gap 6 mutually by filler 11, filler gland 12, hold-down grid 13, and handwheel 17 is screwed onto the top of valve rod 4 by Stem Mut 16, bearing 15 and stop screw 18, and the rotation of handwheel 17 will move up and down by valve rod 4 drive cock bodys 3; The middle part of valve rod 4 is provided with handle 14, and the rotation of handle 14 can drive cock body 3 by valve rod 4 and rotate synchronously.
