Abstract
The invention discloses a plug cock type mud valve which is a valve with a straight through structure. Transverse through holes at the left and right ends of the valve body are communicated with an upward through hole in the middle; a plug cock installed in the upward through hole of the valve body is sealed by a valve seat; the valve seat is fixed on the valve body by pins; the large-diameter section of the plug cock is provided with a radial through hole; elastic sealed bearings are respectively arranged between the bottom end surface of the plug cock and the valve body and between the staircase on the large-diameter section and the gland bush; the plug cock is limited by being in threaded connection with the valve body by the gland bush; the valve cover is connected with the valve body by screw bolts; the top end of the plug cock is connected with a wrench provided with a spacing pin; the plug cock can rotate 0-90 DEG; and sealing rings are respectively embedded in the axial through holes at the left and right ends of the valve body to cooperate with the external wall for sealing. The valve with a plug cock structure has the advantage of convenient and rapid opening/closing operations, can quickly get through or cut off the medium flow, and can not impact and wear the valve due to the accelerated flow of the solid and liquid media. In addition, the split structure of the valve body has slight fluctuating condition, and the sealing of the valve seat on the other side is reinforced under the pressure of the media when the valve is closed.
Description
Technical field
The present invention relates to a kind of manually operated valve, specifically, the present invention relates to a kind of manual mud valve.
Background technique
During the oil drilling construction, a large amount of high pressure drilling liquid and mud thereof are carried by the circulation manifold, and the liquid flow control device in the circulation manifold is a mud valve.The mud valve of prior art is a gate valve structure, and such innervalve assembly is a screw mechanism, can effectively realize the opening and closing operation of valve.But, realize that opening of valves or the process of closing are slower, valve be in initial opening or near the dwell period time longer relatively, this stage is little because of effective area of passage of valve, high pressure drilling liquid and mud speed rate thereof are accelerated.Because of the mixture of drilling fluid and mud is a solid-liquid mixture, solid particle wherein at a high speed by the time valve inside caused bump, bump causes wearing and tearing.It is slower that prior art is regulated process, the degree of wear in the inevitable weighted valve, and repeatedly repeated wear easily causes valve to damage.Oil drilling equipment is subjected to structural limitations, and circulation manifold mounting point is narrow, in case mud valve damages, it is difficult to change, maintenance difficult, and this situation is unfavorable for drilling operation safety.
Summary of the invention
The present invention 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 present invention 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 two slices watts of shape main valve seats and two slices watts of shape auxiliary-seats, 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 present invention 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.
