Abstract
The utility model relates to a valve, in particular to a swing check valve with seal. The swing check valve with the seal is mainly used for solving the technical problems that in the prior art, a valve is complex in structure, high in manufacturing cost, inconvenient to open and close and short in service life. The swing check valve with the seal comprises a valve body (1). The swing check valve with the seal is characterized in that a water inlet (2) and a water outlet (3) are formed in the valve body (1), a support (4) is arranged in the valve body, a rocker arm (6) is hinged to the support through a pin (5), a valve clack (7) which can block the water inlet is connected at the outer end of the rocker arm, a valve base (8) is arranged at the position of the water inlet in an inclined mode, a bonnet (10) is connected at the upper end of the valve body through studs (9), a graphite gasket (11) is arranged on the valve base, and a sealing gasket (13) which can make contact with the graphite gasket is arranged on the bottom surface of the valve clack.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of Swing check valve with sealing.
Background technique
Valve is controlling component in the pipeline fluid delivery system, and it is to change path section and media flow direction, has water conservancy diversion, by functions such as, throttling, non-return, shunting or overflow releases.The valve that is used for fluid control, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are various.Valve can be used for controlling all kinds fluid ground such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid and flows, the working pressure of valve can be from 0.0013MPa to 1000MPa ultrahigh pressure, operating temperature is from the high temperature of-269 ℃ ultralow temperature to 1430 ℃.The control of valve can be adopted the multiple kind of drive, as manual, electronic, surge, pneumatic, worm gear, electromagnetism is moving, electricity surges, gas-liquid is moved, 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 to realize its control function.But existing valve mechanism is comparatively complicated, and manufacture cost is higher, opens and closes comparatively inconvenience, and working life is shorter.
The model utility content
The utility model provides a kind of Swing check valve with sealing, and it mainly is that to solve the existing in prior technology valve mechanism comparatively complicated, and manufacture cost is higher, opens and closes comparatively inconvenience, the technical problem that working life is short etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The Swing check valve of band sealing of the present utility model, comprise valve body, described valve body is provided with water intake, water outlet, be provided with support in the valve body, be hinged with rocking arm by pin on the support, the rocking arm outer end is connected with the flap that can stop up water intake, the water inlet is provided with the valve seat that is obliquely installed, the valve body upper end is connected with valve gap by stud bolt, and valve seat is provided with Graphite pad, and the flap bottom surface is provided with the gasket seal that can contact Graphite pad.
As preferably, the outer end of described water intake, water outlet all is provided with adpting flange.
Therefore, valve mechanism of the present utility model is comparatively simple, reasonable, and manufacture cost is lower, and it is comparatively convenient to process, and it is comparatively easy to open and close, and working life is higher.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
