Abstract
The utility model relates to a valve, in particular to an overflow valve with limiting blocks. The overflow valve mainly solves the technical problems that a valve 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 overflow valve comprises a valve body (1) and is characterized in that a valve deck (2) is connected to the upper end of the valve body (1), an oil inlet (3), an oil outlet (4) and an oil overflow opening (5) are formed in the valve body (1), the oil inlet (3) is always communicated with the oil outlet (4), the central axis of the oil outlet (4) is located above the central axis of the oil inlet (3), a valve main body (6) is arranged between the oil outlet (4) and the oil inlet (3), a spring (7) is connected to the valve main body (6), a spring cushion (8) is connected to the upper end of the spring (7), a threaded rod (9) is connected to the spring cushion (8), and the limiting blocks (10) capable of blocking the spring cushion (8) are arranged on the inner surface of the valve deck (2).
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of relief valve with limiting stopper.
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 relief valve with limiting stopper, 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:
Relief valve with limiting stopper 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, between oil outlet and filler opening, be provided with valve, valve is connected with spring, and spring upper end is connected with spring pad, spring pad is connected with screw rod, and valve gap internal surface is provided with the limiting stopper that can block spring pad.
As preferably, between described valve body and valve gap, be provided with oil-leakage-prevention pad.
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 relief valve with limiting stopper of this example, as Fig. 1, comprise valve body 1, 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, spring upper end is connected with spring pad 8, and spring pad is connected with screw rod 9, and valve gap internal surface is provided with the limiting stopper 10 that can block spring pad.Between valve body and valve gap, be provided with oil-leakage-prevention pad 11.
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.
