Abstract
The invention discloses a flat valve. According to the flat valve, a circle of metal material is directly welded on a valve body in an overlaid mode to substitute for a valve base, a gate is in an expansible two-clack type which is composed of a left clack and a right clack, and middle portions of the left and right clacks are connected through a spring. According to the flat valve, no valve base part exists, and no soft sealing material is used. The valve is not affected by high temperatures and low temperatures. The sealing range of the valve is extended. Meanwhile, the size of the valve body can be reduced, the weight can be reduced, and the cost can be saved.
Description
Technical field
The present invention relates to the valve that a kind of rate-of flow control gear, especially wellhead assembly, throttle kill manifold and oil and gas pipeline are used.
Background technique
At present, the valve that known wellhead assembly, throttle kill manifold and oil and gas pipeline are used, generally, flap type is made of major parts such as valve body, valve rod, flashboard, valve seats.The main sealing pair of flap type has two, and the one, seal between flashboard and the valve seat; The 2nd, seal between valve seat and the valve body.The sealing of flashboard and valve seat is easy to accomplish that the sealing of valve seat and valve body adds soft sealing material at valve seat external diameter and valve seat back usually with metal sealing.Soft sealing material is subject to the restriction of temperature, and high temperature and low temperature all affect the sealing effect of valve, even loses efficacy.
Summary of the invention
The present invention is directed to the deficiency that existing above problem exists, provide a kind of metallic seal flat plate valve to possess general wellhead assembly, throttle kill manifold and oil and gas pipeline with outside the control media flow of valve, can also be under high temperature and worst cold case, normal operation.
The technical solution adopted for the present invention to solve the technical problems is:
Directly built-up welding one circle metallic material replaces valve seat on valve body, and two debated about flashboard adopted, and middlely expansive two debates pattern with what spring connected.
Beneficial effect of the present invention: saved the valve seat part, need not adopt soft sealing material.Can not be subjected to the impact of high temperature and low temperature.Enlarged the sealing range of valve.Can also dwindle simultaneously the volume of valve body, cost is saved in weight reduction.

Embodiment
As depicted in figs. 1 and 2, valve body of the present invention (1) and flashboard (2) contact position built-up welding one circle metal (11), flashboard (2) is put into valve body (1), and flashboard (2) upper end has T-shaped groove to be connected with valve rod (3).
Shown in Fig. 3, Fig. 4 a, Fig. 4 b, Fig. 5 a, Fig. 5 b, flashboard (2) is comprised of left flashboard (21), right flashboard (22), pin (23) and spring (24).Connect together by pin (23) with left flashboard (21) and right flashboard (22).
During throttle down, it is descending that valve rod (3) takes flashboard (2) to, until right flashboard (22) bottom (221) contacts with valve body (1), right flashboard this moment (22) can not move down, left flashboard (21) continues to move down, because left flashboard (21) is the conical surface with right flashboard (22) junction, thereby left flashboard (21) and right flashboard (22) are strutted to the left and right, the sealing surface and valve body (1) the built-up welding one circle metal (11) that reach flashboard (2) are fitted, and reach sealing effect.During Open valve, it is up that valve rod (3) takes flashboard (2) to, left flashboard (21) shrinks under the effect of spring (24) with right flashboard (22), and the sealing surface of flashboard (2) and valve body (1) built-up welding one circle metal (11) are separated.Thereby easily open valve.
It is to be noted and any distortion of having done according to the specific embodiment of the present invention all do not break away from the scope that spirit of the present invention and claim are put down in writing.
Claims (1)
1. a flap type comprises valve body, have valve pocket in the valve body and can move up and down to open or close along valve pocket the flashboard of flap type, flashboard directly and on the valve body overlay cladding seal.It is characterized in that: directly built-up welding one circle metallic material replaces valve seat on valve body, and two debated about flashboard adopted, and middlely expansive two debates pattern with what spring connected.Flashboard top has T-shaped groove to be used for linking to each other with valve rod.
