Abstract
The utility model relates to a valve, in particular to an overflow valve with a detachable screw hole. The overflow valve comprises a valve body, wherein the upper end of the valve body is connected with a valve cover, an oil inlet, an oil outlet and an oil overflow port are arranged in the valve body, the oil inlet is always communicated with the oil outlet, the central axis of the oil outlet is positioned above the central axis of the oil inlet, a valve is arranged between the oil outlet and the oil inlet and is connected with a spring, the upper end of the spring is connected with a spring pad, the spring pad is connected with a screw, the bottom surface of the valve body is provided with the detachable screw hole, and an oil leakage prevention gasket is arranged between the valve body and the valve cover. Thus, the overflow valve is relatively simple and reasonable in structure, relatively low in manufacturing cost, relatively convenient to process, relatively easy in opening and closing and relatively long in service life.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of relief valve with the dismounting screw.
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 relief valve with the dismounting screw, 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:
The relief valve of band dismounting screw of the present utility model, comprise valve body, described valve body upper end is connected with valve gap, and valve body is provided with filler opening, oil outlet, oil spilling mouth, and filler opening is communicated with all the time with oil outlet, the medial axis of oil outlet is positioned at the top, medial axis of filler opening, be provided with valve between oil outlet and filler opening, valve is connected with spring, and the spring upper end is connected with spring pad, spring pad is connected with screw rod, has the dismounting screw on the bottom surface of valve body.
As preferably, be provided with the oil-leakage-prevention pad between described valve body and valve gap.
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 relief valve of the band dismounting screw of this example, as Fig. 1, comprise valve body 1, the valve body upper end is connected with valve gap 2, valve body is provided with filler opening 3, oil outlet 4, oil spilling mouth 5, filler opening is communicated with all the time with oil outlet, and the medial axis of oil outlet is positioned at the top, medial axis of filler opening, is provided with valve 6 between oil outlet and filler opening, valve is connected with spring 7, the spring upper end is connected with spring pad 8, and spring pad is connected with screw rod 9, has dismounting screw 10 on the bottom surface of valve body.Be provided with oil-leakage-prevention pad 11 between valve body and valve gap.
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.
