The model utility content
The utility model is primarily aimed at the deficiencies in the prior art, propose a kind of simple in structure, open and close swift to operate, good airproof performance, wearing and tearing less, the plug cock type mud valve of long service life.
The utility model is achieved through the following technical solutions technical goal.
Plug cock type mud valve, it comprises valve body, elastic packing bearing, valve seat, gland, valve gap, wrench, pin, seal ring, cock, bolt and position limit pin.Described valve body is the bilateral symmetry member, about the end cross through hole and middle part through hole up link.Described cock is the stepped shaft cylinder axis, the enlarged diameter section middle part is provided with a radial direction through hole, cock is installed in the valve body through hole up, the center of end cross through hole is contour about the radial direction through hole of cock and valve body, gland and valve gap order and cock Spielpassung, gland is threaded with valve body, and valve gap is connected with valve body by bolt, and the wrench that the cock top is connected with position limit pin constitutes manually 0～90 ° of structure of rotation.Its improvements are: between described valve body and the cock enlarged diameter section by valve base sealing.Described valve seat is for dividing body structure, and it is made up of each two slices watts of shape main valve seat and auxiliary-seat, and main valve seat and auxiliary-seat constitute cylindrical shape alternately on same circumference.Described elastic packing Bearing Installation constitutes the sealing configuration of cock bottom end and valve body between cock bottom end and valve body, the sealing that the cock enlarged diameter section is topped bar between end face and the gland bottom end is born by another elastic packing bearing.Described seal ring is a ring, is embedded in respectively to hold about valve body in the cross through hole, and seal ring cooperates the formation sealing pair with the main valve seat outer wall.
The corresponding valve body cross through hole of main valve seat in said structure place is provided with the through hole of same size, the mounting point of main valve seat with through hole and valve body about end cross through hole coaxial positioning, the main valve seat bottom end is located by pin and valve body.Described auxiliary-seat and seal ring are two material assemblying bodys, and built-in part is a metal frame, and surface layer is a rubber.Auxiliary-seat and seal ring cooperate the formation elastic sealing structure with the component that matches.
The utility model compared with prior art has following good effect:
1, tap structure is simple, and is easy to manufacture, and cost of production is low;
2, the cock rotating operation is quick, and high pressure drilling liquid and mud are few to the brinelling of valve, the long service life of valve;
3, valve seat is for dividing a body structure, and the mounting point trace floats, and when valve cut out, pressure medium compressed the main valve seat of opposite side by cock, had further strengthened the sealability of valve.
