Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of safety valve with stuffing box gland.
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 safety valve with stuffing box gland, 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:
Safety valve with stuffing box gland of the present utility model, comprise valve body, and described valve body is provided with adpting flange, valve body lower end is connected with valve seat, the valve body upper end is fixed with support, is provided with valve rod in support, and the valve rod lower end is provided with flap, on valve rod, cross-under has upper spring seat, lower spring cup, be provided with spring between upper lower spring cup, the top of support is provided with upper cover, and valve seat is provided with stuffing box gland, the inside of flap is fixed with the sealing block of salable valve seat, and the section of sealing block is for falling T-shape.
As preferably, between described valve rod upper end and support, be provided with spacer.
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 safety valve with stuffing box gland of this example, as Fig. 1, comprises valve body 1, valve body is provided with adpting flange, and valve body lower end is connected with valve seat 3, and the valve body upper end is fixed with support 4, be provided with valve rod 5 in support, the valve rod lower end is provided with flap 6, and on valve rod, cross-under has upper spring seat 7, lower spring cup 8, is provided with spring 9 between upper lower spring cup, the top of support is provided with upper cover 10, valve seat is provided with stuffing box gland 11, and the inside of flap is fixed with the sealing block 12 of salable valve seat, and the section of sealing block is for falling T-shape.Be provided with spacer 2 between valve rod upper end and support.
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.
