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
The present invention relates to valve technology field, specifically a kind of high-voltage high-speed throttle down.
Background technique
High-pressure stop valve is a novel valve, is adapted to petroleum drilling and mining industry, without the valve of this kind of structure type in current API6A valve.Mainly for longer in the existing various valve open shut-in time, and a kind of valve that can cut off rapidly fluid of design, it is longer that current API6A valve generally opens the shut-in time, and rotation torque is larger.
Therefore, for overcoming the deficiency of above-mentioned technology and design can a kind of high-voltage high-speed throttle down of valve of quick closedown oil circuit, inventor's problem to be solved just.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of high-voltage high-speed throttle down, its structure is simple, easy to use, can quick closedown oil circuit, has extraordinary use value.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high-voltage high-speed throttle down, it is characterized in that: valve comprises valve body, valve seat, flap, valve rod, feather key, handwheel, Stem Mut, the built-in movable adjustment flap of valve, valve seat and valve body adopt nonmetal with soft metal double-sealing, flap circumference is carried out gap circumference by feather key and is fixed, Stem Mut be connected with valve rod, valve stem tip is connected with handwheel.
The invention has the beneficial effects as follows:
1, the present invention is by the architecture advances to valve internal, and the shut-in time overcoming existing valve is longer, and the problem that rotation torque is larger, quick closedown oil circuit can be realized, have extraordinary effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1-valve body; 2-valve seat; 3-flap; 4-valve rod; 5-feather key; 6-handwheel; 7-Stem Mut.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further, should be understood that these embodiments are only not used in for illustration of the present invention and limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values drop on application appended claims limited range equally.
Fig. 1 is a kind of high-voltage high-speed throttle down of the present invention structural representation, valve comprises valve body 1, valve seat 2, flap 3, valve rod 4, feather key 5, handwheel 6, Stem Mut 7, the built-in movable adjustment flap 3 of valve, valve seat 2 and valve body 1 adopt nonmetal with soft metal double-sealing, flap 3 circumference is carried out gap circumference by feather key 5 and is fixed, Stem Mut 7 be connected with valve rod 4, valve rod 4 top is connected with handwheel 6.
High-pressure stop valve of the present invention is a kind of novel valve that a API6A and API6D combines, valve both sides adopt standard A PI Flange joint, connect sealing reliable, the present invention is in use: the built-in movable adjustment flap 3 of valve, automatically the center of being sealed and matched can be found accurately, carry out and reliably end sealing fast, valve seat 2 and valve body 1 adopt nonmetal with soft metal double-sealing, flap 3 circumference is carried out gap circumference by feather key 5 and is fixed, axially by the motion of the rotating band ovable valve stem about 4 of Stem Mut 7, during throttle down, flap 3 has a downward pressure difference, advance sealing, also can rotate counterclockwise handwheel 6 simultaneously, flap 3 is made to withstand valve seat 2, realize machinery forced cut-off sealing.
