Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of boiler water circulating pump outlet valve with filler.
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 boiler water circulating pump outlet valve with filler, 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 boiler water circulating pump outlet valve of band filler of the present utility model, comprise valve body, described valve body upper end is connected with valve gap, cross-under has valve rod in the valve gap, the valve rod lower end is connected with flap, valve body lower end is connected with the first crooked valve port, the second crooked valve port, the valve rod upper end is connected with handwheel by Stem Mut, and the valve body upper end is connected with support, and handwheel is located at the top of support upper end, the valve rod middle part is connected with the filler seat, be provided with filler between filler seat and the valve gap, filler seat top is provided with pressing plate, and pressing plate is connected with locating stud, locating stud is hinged on the strand earrings, and the strand earrings is fixed on the valve gap.
As preferably, be provided with impact block between described handwheel and the support.
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.
