Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the butterfly valves in the prior art are laborious to use, and when the water pressure is high, it is difficult to control the valve to open and close quickly, which requires a lot of physical effort, which is not labor-saving enough, and at the same time, the operating rod is stuck. Finally, there is no remedial measure to close the valve, resulting in the disadvantage that emergency situations cannot be easily dealt with, and a manually operated butterfly valve that can perform labor-saving operation is proposed

Abstract

The invention belongs to the field of butterfly valves, particularly relates to a manually-operated butterfly valve capable of being operated in a labor-saving manner, and aims to solve the problems that an existing butterfly valve is labor-saving in use, is difficult to control the valve to be quickly opened and closed when the water pressure is high, needs to consume a large amount of physical power, is not labor-saving enough, and cannot be closed by no remedial measures after an operating rod is blocked. In order to solve the problem that in the prior art, due to the fact that a valve body is arranged, the emergency situation cannot be dealt with easily, the following scheme is provided that the valve body comprises a valve body, the top of the valve body is fixedly connected with two supporting frames which are symmetrically arranged, and the tops of the two supporting frames are fixedly connected with the same bottom plate, the labor-saving function is achieved through a labor-saving assembly, and the operation difficulty can be greatly reduced; meanwhile, when the device is aged and the function of opening and closing the valve cannot be achieved by pushing the grip, the worm and the worm gear are not meshed any more, then the rack and the third gear are used for driving the valve rod to rotate, and the device is used for coping with emergency situations and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of butterfly valves, in particular to a manually operated butterfly valve capable of labor-saving operation. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switch control of low-pressure pipeline medium. A kind of valve, the valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. [0003] The existing butterfly valve is laborious to use, and when the water pressure is high, it is difficult to control the valve to open and close quickly, which require...
