Abstract
The utility model relates to a valve, in particular to a hand wheel driven flat valve with a check valve, which mainly solves the technical problems that the valve structure is relatively complex, the manufacturing cost is relatively high, the opening and closing are relatively inconvenient, the service life is relatively short and the like existing in the prior art. The hand wheel driven flat valve comprises a valve body (1), and is characterized in that a water inlet and outlet (2) is arranged in the valve body (1), the valve body is internally provided with a valve seat (3), the upper end of the valve body is fixedly provided with a valve cover (5) which is connected with the check valve (4), the check valve is communicated with the interior of the valve body, a valve rod (6) is connected into the valve cover in a penetrating manner, the lower end of the valve rod is connected with a valve plate (7), the upper end of the valve rod is in threaded connection with a valve rod nut (8), and the valve rod nut is connected with a hand wheel (9).
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of handwheel with one-way valve and drives flap type.
Background technique
Valve is controlling component in the 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 and drives or automechanism makes it do lifting, slippage, swing or rotation motion, thus the size that changes its Flow area is controlled function to realize it.But existing valve mechanism is comparatively complicated, and manufacture cost is higher, open and close comparatively inconvenience, working life is shorter.
The model utility content
The utility model is to provide a kind of handwheel with one-way valve and drives flap type, 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:
Handwheel with one-way valve of the present utility model drives flap type, comprise valve body, described valve body is provided with intake-outlet, is provided with valve seat in valve body, and valve body top is fixed with valve gap, be connected with one-way valve on valve gap, one-way valve is communicated with valve inner, and in valve gap, cross-under has valve rod, and the valve rod lower end is connected with valve plate, the valve rod upper end Stem Mut that has been threaded, Stem Mut connects handwheel.
As preferably, outside, described valve rod upper end is provided with protective housing.
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.
The 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 handwheel with one-way valve of this example drives flap type, as Fig. 1, comprise valve body 1, valve body is provided with intake-outlet 2, be provided with valve seat 3 in valve body, valve body top is fixed with valve gap 5, is connected with one-way valve 4 on valve gap, and one-way valve is communicated with valve inner, in valve gap, cross-under has valve rod 6, the valve rod lower end is connected with valve plate 7, the valve rod upper end Stem Mut 8 that has been threaded, and Stem Mut connects handwheel 9.Outside, valve rod upper end is provided with protective housing 10.
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 all are encompassed among the scope of the claims of the present utility model.
Claims (2)
1. the handwheel with one-way valve drives flap type, comprise valve body (1), it is characterized in that described valve body (1) is provided with intake-outlet (2), be provided with valve seat (3) in valve body, valve body top is fixed with valve gap (5), be connected with one-way valve (4) on valve gap, one-way valve is communicated with valve inner, in valve gap, cross-under has valve rod (6), the valve rod lower end is connected with valve plate (7), the valve rod upper end Stem Mut (8) that has been threaded, Stem Mut connects handwheel (9).
