Abstract
The utility model relates to a valve, in particular to a corrugated pipe sealing stop valve with a handwheel. The corrugated pipe sealing stop valve with the handwheel is mainly used for solving the technical problems that in the prior art, a valve is complex in structure, high in manufacturing cost, inconvenient to open and close and short in service life. The corrugated pipe sealing stop valve with the handwheel comprises a valve body (1). The corrugated pipe sealing stop valve with the handwheel is characterized in that a valve chamber (2) is arranged in the valve body (1), the valve chamber is communicated with a left water inlet-and-outlet port (3) and a right water inlet-and-outlet port (4), a channel (5) is arranged between the left water inlet-and-outlet port and the water right inlet-and-outlet port, a valve rod (6) is arranged in the valve chamber, a valve clack (7) which can block the channel is connected with the lower end of the valve rod, a corrugated pipe (8) is arranged outside the valve rod, a valve cover (10) is connected on the upper portion of the valve body through a stud (9), a valve rod nut (11) is connected with the upper end of the valve rod in a threaded mode, and the handwheel (14) is connected with the upper end of the valve rod nut through a gland nut (13).
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of sylphon seal stop valve with handwheel.
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 sylphon seal stop valve with handwheel, 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 sylphon seal stop valve of band handwheel of the present utility model, comprise valve body, be provided with valve pocket in the described valve body, valve pocket is communicated with left intake-outlet, right intake-outlet, is provided with passage between the left and right intake-outlet, be provided with valve rod in the valve pocket, but the valve rod lower end is connected with the flap of blocking channel, and the valve rod outside is provided with bellows, and valve body top is connected with valve gap by stud bolt, valve rod upper end screw thread is connected with Stem Mut, and the Stem Mut upper end is connected with handwheel by gland nut.
As preferably, the outer end of described left intake-outlet, right intake-outlet all is provided with adpting flange.
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.
Description of drawings
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 sylphon seal stop valve of the band handwheel of this example, as Fig. 1, comprise valve body 1, be provided with valve pocket 2 in the valve body, valve pocket is communicated with left intake-outlet 3, right intake-outlet 4, be provided with passage 5 between the left and right intake-outlet, be provided with valve rod 6 in the valve pocket, but the valve rod lower end is connected with the flap 7 of blocking channel, the valve rod outside is provided with bellows 8, valve body top is connected with valve gap 10 by stud bolt 9, and valve rod upper end screw thread is connected with Stem Mut 11, and the Stem Mut upper end is connected with handwheel 14 by gland nut 13.The outer end of left side intake-outlet, right intake-outlet all is provided with adpting flange 12.
The above only is specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, 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 claim of the present utility model.
