An Intelligent Stop Valve Against Rainwater Erosion

Abstract

The invention relates to a rainwater-erosion-resistant intelligent-type stop valve convenient to operate and capable of saving labor. The rainwater-erosion-resistant intelligent-type stop valve comprises a handle, a valve rod, a control pipe and two water pipes. The handle comprises a center block, a circular ring and at least two connecting rods, and the periphery of the circular ring is providedwith at least two extending mechanisms. Rain sheltering mechanisms are arranged above the water pipes, and extending mechanisms comprise hinged units, hollow pipes and extending pipes. The rain sheltering mechanisms comprise rain sheltering units and fixing units, wherein the rain sheltering units comprise baffles, supporting plates and side plates, and the fixing units comprise panels, insertingrods and fixing pipes. According to the rainwater-erosion-resistant intelligent-type stop valve convenient to operate and capable of saving the labor, through the rain sheltering mechanisms and sheltering plates, rainwater is prevented from immersing into the control pipe, rust of the rainwater-erosion-resistant intelligent-type stop valve is avoided, and safe use is ensured; and more than that,the moment of acting force for driving the handle to rotate can be greatly increased through the extending mechanisms, the consumed acting force needed to drive the valve rod is saved, and thus rotation of the handle saves more labor and is more convenient, so that the practicability of the rainwater-erosion-resistant intelligent-type stop valve is improved.

Description

technical field [0001] The invention relates to the field of hydraulic valve equipment, in particular to an intelligent stop valve that prevents rainwater erosion. Background technique [0002] Globe valve, also called gate valve, is one of the most widely used valves. It is popular because the friction between the sealing surfaces is small during the opening and closing process, it is relatively durable, the opening height is not large, it is easy to manufacture, and it is easy to maintain , not only for medium and low pressure, but also for high pressure. The closing principle of the globe valve is to rely on the pressure of the valve rod to make the sealing surface of the valve disc and the sealing surface of the valve seat fit closely to organize the flow of medium. [0003] The stop valve is a forced sealing valve. Due to the large fluid resistance in the stop valve, it requires a lot of force when the valve is opened and closed. On the existing stop valve, the length ...

AI Technical Summary

Problems solved by technology

[0003] The stop valve is a forced sealing valve. Due to the large fluid resistance in the stop valve, it requires a lot of force when the valve is opened and closed. On the existing stop valve, the length of the rotating handle is limited, resulting in a limited torque. To drive the disc to move, the operator needs to spend a lot of effort to open and close the valve. Not only that, some globe valves outdoors, due to the lack of corresponding protective devices, are exposed to wind and rain, and rainwater seeps into the valve, which is easy to cause damage to the valve. The corrosion of the components not only makes the opening and closing of the valve more laborious, but also affects the cut-off performance of the globe valve, thus reducing the practicability of the equipment
