Problems solved by technology
[0002] The opening and closing part of the globe valve is a plug-shaped disc, the sealing surface is flat or conical, the disc moves linearly along the center line of the fluid, and the valve stem is lifted and lowered by the hand wheel, but there are many problems in this traditional globe valve : One, the fluid resistance is large, and the force required for opening and closing is relatively large; two, problems such as poor adjustability, these problems not only increase the labor intensity of workers, but also reduce work efficiency, and then appear on the market now Electric globe valve, the existing electric globe valve cannot work when there is a problem in its power system, which has brought a huge impact on production

Embodiment Construction
[0016] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings:
[0017] like Figure 1 ~ Figure 4 As shown, a multifunctional globe valve of the present invention includes a controller 1, a three-phase asynchronous motor 2, a transmission rod 3, a valve rod 4, a handwheel 5, a valve flap 7 and a valve body 8. The controller 1 and The three-phase asynchronous motor 2 and the transmission rod 3 at the bottom of the three-phase asynchronous motor 2 are connected. The three-phase asynchronous motor 2 is fixed on the valve body 8 through the bracket 9. The upper side of the valve body 8 is vertically provided with a handwheel 5, and the handwheel 5 passes through. The connecting rod and the upper part of the valve rod 4 are screwed together, the bottom of the valve rod 4 is connected with the valve flap 7 inside the valve body 8, the handle 6 is provided on the handwheel 5, and the top of the valve rod 4 is provid...

The invention relates to a multifunctional stop valve, which comprises a controller, a three-phase asynchronous motor, a transmission rod, a valve rod, a hand wheel, a valve clack and a valve body, wherein the controller is connected with the three-phase asynchronous motor and the transmission rod at the bottom of the three-phase asynchronous motor; the three-phase asynchronous motor is fixed on the valve body through a bracket; the hand wheel is vertically arranged on the side surface of the upper part of the valve body; the hand wheel is in threaded connection with the upper part of the valve rod through a connecting rod; the bottom of the valve rod is connected with the valve clack in the valve body; a handle is arranged on the hand wheel; and a hexagonal bulge is arranged at the top of the valve rod. Compared with the prior art, the multifunctional stop valve has the benefits as follows: the multifunctional stop valve has the characteristics of being low in cost, simple in structure, convenient to use, reasonable in design, scientific and practical; and since the controller controls the transmission rod to be connected with the valve rod, the stop valve can be electrically-driven and hand-operated, the problem that the stop valve cannot work due to the electric power system failure is solved and the stop valve has a wide market prospect.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a multifunctional shut-off valve. Background technique [0002] The opening and closing part of the globe valve is a plug-shaped valve disc, the sealing surface is flat or conical, the valve disc moves linearly along the center line of the fluid, and the valve stem is lifted and lowered by the handwheel, and there are many problems with this traditional globe valve. : First, the fluid resistance is large, and the force required for opening and closing is large; second, the problems such as poor adjustment, these problems not only increase the labor intensity of workers, but also reduce work efficiency, and now there are problems in the market. Electric globe valve, the existing electric globe valve cannot work when there is a problem with its power system, which has a huge impact on production. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide...
