Embodiment Construction

[0010] The present invention will be further described below in conjunction with specific examples. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0011] figure 1 It is a structural diagram of a high-pressure quick-closing valve of the present invention. The valve includes a valve body 1, a valve seat 2, a valve disc 3, a valve stem 4, a guide key 5, a hand wheel 6, and a valve stem nut 7. The valve has a built-in movable adjustable valve disc. 3. The valve seat 2 and the valve body 1 are double-sealed with non-metal and soft metal. The circumferential direction of the valve ...

Abstract

The invention relates to the technical field of valves, in particular to a high-pressure rapid-closure valve. The high-pressure rapid-closure valve comprises a valve body, a valve seat, a valve clack, a valve rod, a guiding key, a hand wheel and a valve rod nut, wherein the valve clack movably adjustable is arranged in the valve, the valve seat and the valve body are dually sealed by nonmetal and soft metal, the valve clack is circumferentially fixed at an interval by the guiding key, the valve rod nut is connected with the valve rod, and the top end of the valve rod is connected with the hand wheel. By modifying the internal structure of the valve, the problem that an existing valve is long in closure time and large in rotation torque is solved, oilways can be rapidly closed and good effect is achieved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a high-pressure fast closing valve. Background technique [0002] The high-pressure globe valve is a new type of valve, which is suitable for the oil drilling industry. At present, there is no valve of this type in the API6A valve. It is mainly designed for the existing various valves that open and close for a long time, and a valve that can quickly cut off the fluid. At present, API6A valves generally have a long opening and closing time, and the rotation torque is relatively large. [0003] Therefore, in order to overcome the deficiency of above-mentioned technology, design a kind of high-pressure fast shut-off valve that can close the valve of oil circuit quickly, just the problem that the inventor will solve. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a high-pressure quick-closing valve,...
