Abstract
The utility model relates to a valve, in particular to a high-water-pressure stop valve with the positioning function. The high-water-pressure stop 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 high-water-pressure stop valve comprises a valve body, a water inlet channel and a water outlet channel are formed in the lower portion of the valve body in a slant mode, the inner end of the water outlet channel is higher than the inner end of the water inlet channel, a valve seat is arranged between the inner end of the water outlet channel and the inner end of the water inlet channel, a valve clack is in contact with the valve seat and connected to a valve rod, a threaded face is arranged at the upper end of the valve rod, a valve rod nut is in threaded connection to the threaded face, a valve deck is connected to the valve body, the valve rod nut is fixed on the valve deck, a positioning protruding block is arranged on the valve body, the valve deck is fixed on the positioning protruding block through a positioning screw, and a positioning ring capable of being in contact with the lower end face of the valve rod nut is arranged at the lower end of the threaded face of the valve rod.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of high hydraulic pressure stop valve with location.
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 high hydraulic pressure stop valve with location, 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 high hydraulic pressure stop valve of band of the present utility model location, comprise valve body, described valve body lower portion is provided with intake tunnel and exhalant canal, intake tunnel and exhalant canal are all for being obliquely installed, and the inner height of exhalant canal is higher than the inner height of intake tunnel, between the inner of exhalant canal and the inner of intake tunnel, be provided with valve seat, valve seat contact has flap, flap is connected on valve rod, valve rod upper end is provided with flank of thread, Stem Mut has been threaded on flank of thread, valve body is connected with valve gap, Stem Mut is fixed on valve gap, valve body is provided with locating bump, valve gap is fixed on locating bump by positioning screwn, the flank of thread lower end of valve rod is provided with the positioning ring that can contact Stem Mut lower end surface.
As preferably, described valve rod upper end is connected with handwheel, and handwheel upper end is fixed with circular nameplate by nut.
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 high hydraulic pressure stop valve of the band location of this example, as Fig. 1, comprise valve body 1, valve body lower portion is provided with intake tunnel 2 and exhalant canal 3, intake tunnel and exhalant canal are all for being obliquely installed, and the inner height of exhalant canal is higher than the inner height of intake tunnel, between the inner of exhalant canal and the inner of intake tunnel, be provided with valve seat 4, valve seat contact has flap 5, flap is connected on valve rod 6, valve rod upper end is provided with flank of thread, Stem Mut 7 has been threaded on flank of thread, valve body is connected with valve gap 8, Stem Mut is fixed on valve gap, valve body is provided with locating bump, valve gap is fixed on locating bump by positioning screwn 12, the flank of thread lower end of valve rod is provided with the positioning ring 13 that can contact Stem Mut lower end surface.Valve rod upper end is connected with handwheel 9, and handwheel upper end is fixed with circular nameplate 11 by nut 10.
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.
