Abstract

The utility model provides a cubic high pressure angle-type disconnecting valve. A two-section type valve rod is adopted and connected with the disconnecting check into a whole by a shaft joint; one end of a lower valve rod is manufactured into a valve clack; the valve clack is conical; the valve clack and a sealing surface of the valve body have a rigid and sealed structure; a stuffing box is arranged between the lower valve rod and the valve body; the stuffing box, the lower valve rod and the valve body are filled with stuffing and a high-strength gasket to realize a dual-sealing mode; the stuffing is tightly pressed and sealed by a stuffing gland bush; the upper end face of the stuffing gland bush is provided with two adjusting bolts for connecting a bracket to form a compensatory sealed structure; a connecting end face between the valve body and the stuffing box is provided with a seam fit; the edge of a seam of the valve body is provided with a sealed line groove; an upper valve rod and a nut of the valve rod are matched and fixed on the bracket; one end of the upper valve rod is fixed with a rotary handle by screw threads; and the upper valve rod spirally rotates and drives the lower valve rod to carry out linear motion. The disconnecting valve has the advantages of reliable sealing performance, labor-saving opening and closing, etc., and can be widely applied to a pipeline system in industries of petroleum, medicine, chemical engineering, etc. , under the environmental conditions of high temperature and high pressure.

Description

Fang Tigao presses Angle Stop valves
Technical field
The utility model belongs to valve class technical field, and particularly a kind of side's height is pressed Angle Stop valves.
Background technique
At present, the high-pressure stop valve kind that market provides is a lot, and its seal form adopts aciculiform or spherical sealing configuration mostly.Because this type of valve working environment is under high temperature, condition of high voltage, valve for the aciculiform sealing configuration, flap be taper and valve seat lead the joint conical surface fit tightly and push realize the sealing, intermetallic sealing area is bigger, the passage bore is little, and this spline structure is the general assurance technological requirement that is difficult in course of working.In addition, sealing surface is in the passage of various media, have residual between the sealing surface, cause erosion, abrasion sealing surface, or impurity produces grinding between sealing surface, make sealing surface wear cause leakage, especially use the high-pressure stop valve sealing reliability lower in the high-pressure gas medium environment, gas leak phenomenon is serious.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes stop valve under hyperbaric environment, solve stop valve in the medium-term and long-term unsolved run, drip, leak phenomenon of pipe-line system, improve the sealing reliability of stop valve, prolong the working life of stop valve, reduce the fabricating cost of stop valve simultaneously.
The technical scheme in the invention for solving the technical problem is: square height is pressed Angle Stop valves, comprise handle, valve body, support, upper valve rod, lower valve rod, Stuffing box, Gland, coupling, Stem Mut, filler, high-strength pad, regulate bolt, compositions such as flap, upper valve rod and lower valve rod are that bipartial fuses by coupling, flap and lower valve rod are an integral body, be provided with Stuffing box between valve body and the lower valve rod, Stuffing box and lower valve rod and valve body are equipped with filler and high-strengthly pad existing double-sealing mode, filler compresses sealing by Gland, the Gland upper-end surface is provided with the adjusting bolt of two connection supports, constitute compensation sealing configuration, flap is that conical sealing surface with valve body adopts the rigid seal structure, valve body is connected end face and is provided with the rim of the mouth cooperation with Stuffing box, be provided with the packing seal wire casing in the edge in valve body rim of the mouth, place high-strength pad in the groove, upper valve rod and Stem Mut match, and Stem Mut is fixed on the support, and the upper end portion of upper valve rod is provided with screw thread handle is housed.
The beneficial effects of the utility model are: strengthen the sealing effect between valve rod and valve body, improve the working life of stuffing box packing, and adopt the high-strength polyester material as the valve stem seal packing, regulating the seal degree of sealed packing to valve rod, take on Stuffing box, to be provided with the adjusting bolt, adjusting is to the optimum pressure of sealed packing, prevent the leakage of valve body and Stuffing box joint, on the junction surface of valve body and Stuffing box, be provided with the rim of the mouth formula and cooperate, and be provided with the sealing wire casing, and the Security that high-strength pad improves sealing is installed at the edge in valve body rim of the mouth, gas experiment pressure reaches 48Mpa, does not have and runs, emit, drip, leak phenomenon.
