Abstract
The utility model relates to a valve, in particular to an adjustable parallel double-disc gate valve. The adjustable parallel double-disc gate valve mainly resolves the technical problems that a valve existing in the prior art is complex in structure, high in manufacturing cost, inconvenient to open and close, short in service life and the like. The adjustable parallel double-disc gate valve comprises a valve body (1), and is characterized in that two discs (2) are symmetrically arranged in the valve body (1), a wedge-shaped block (3) is connected between the upper ends of the discs in a clamped mode, the wedge-shaped block is connected with a valve rod (4), an expansion block (5) is connected between the lower ends of the discs, an adjusting block (13) is connected to a position, at the lower end of the expansion block, of the valve body, the upper end of the valve body is connected with a valve cap (6), a support (7) is fixed at the upper end of the valve cap, the valve rod is connected in the support in a penetrated mode, and the upper end of the valve rod is connected with a hand wheel (8).
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of adjustable parallel double-flashboard gate valve.
Background technique
Valve is controlling component in pipeline fluid transporting system, and it is for changing path section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.The valve of controlling for fluid, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are various.Valve can be used for controlling all kinds such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid and fluidly flows, the working pressure of valve can be from 0.0013MPa to 1000MPa ultrahigh pressure, operating temperature is from the high temperature of the ultralow temperature to 1430 of-269 ℃ ℃.The control of valve can adopt the multiple kind of drive, as manual, electronic, surge, pneumatic, worm gear, electromagnetic driven, electricity surge, air-or liquid-operated, spur wheel, umbrella gear driving etc.; Can be under the effect of pressure, temperature or other form transducing signal, by predetermined requirement action, valve relies on driving or automechanism to make it do lifting, slippage, swing or rotation motion, thus the size that changes its Flow area is to realize its control function.But existing valve mechanism is comparatively complicated, and manufacture cost is higher, open and close comparatively inconvenience, working life is shorter.
Model utility content
The utility model is to provide a kind of adjustable parallel double-flashboard gate valve, and it is mainly that to solve the existing valve mechanism of prior art comparatively complicated, and manufacture cost is higher, opens and closes comparatively inconvenience, working life shorter grade technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Adjustable parallel double-flashboard gate valve of the present utility model, comprise valve body, in described valve body, be symmetrically arranged with two shoe brake plates, between the upper end of flashboard, be connected with wedge-shaped blocks, wedge-shaped blocks is connected with valve rod, between the lower end of flashboard, is connected with the piece that rises, rise on the valve body of piece lower end and be connected with adjustment block, the upper end of valve body is connected with valve gap, and valve gap upper end is fixed with support, valve rod cross-under in support and upper end be connected with handwheel.
As preferably, the described valve rod upper end Stem Mut that has been threaded, Stem Mut outside is provided with bearing support, is provided with bearing in bearing support, and bearing support is provided with lubricating cup.
Therefore, valve mechanism of the present utility model is comparatively simple, reasonable, and manufacture cost is lower, and more for convenience, it is comparatively easy to open and close in processing, and working life is higher.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the adjustable parallel double-flashboard gate valve of this example, as Fig. 1, comprise valve body 1, in valve body, be symmetrically arranged with two shoe brake plates 2, between the upper end of flashboard, be connected with wedge-shaped blocks 3, wedge-shaped blocks is connected with valve rod 4, between the lower end of flashboard, be connected with the piece 5 that rises, on the valve body of the piece lower end of rising, be connected with adjustment block 13, the upper end of valve body is connected with valve gap 6, valve gap upper end is fixed with support 7, valve rod cross-under in support and upper end be connected with handwheel 8.The valve rod upper end Stem Mut 9 that has been threaded, Stem Mut outside is provided with bearing support 10, is provided with bearing 11 in bearing support, and bearing support is provided with lubricating cup 12.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
