New product: valve with electromagnetic quick cut-off control

unlimited creativity, great instrument invention. Today, I will introduce to you a national invention authorized patent - a valve with electromagnetic quick cut-off control. The patent was applied for by Tianjin fudes Valve Co., Ltd. and was authorized and announced on July 18, 2017

invention background

the valve is a control component in the fluid transmission system, which has the functions of cut-off, regulation, diversion, prevention of countercurrent, pressure stabilization, diversion or overflow pressure relief. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metal and radioactive media

valves used in fluid control systems, from the simplest stop valves to various valves used in extremely complex automatic control systems, have a wide range of varieties and specifications, and there is no unified production and use standards. Manufacturers often manufacture according to the actual needs of users

in some specific applications, it is necessary to realize the rapid cut-off control of the valve, but there is no unified implementation standard. Therefore, how to realize the rapid and effective cut-off of the valve is an important topic in the foaming process that has been studied in the valve field

invention content

the purpose of the invention is to provide a valve with electromagnetic quick cut-off control, so as to realize the quick and effective cut-off of the valve, so as to meet the use needs of users

in order to realize the purpose of the invention, the invention provides a valve with electromagnetic quick cut-off control. The valve includes a valve body and a control part, and the valve body includes a valve body and a valve rod; The control part comprises a spring, an upper horizontal plate, a support rod, an upper suction rod, an upper fixing block, a locking rod, a lower supporting plate, a lower electromagnetic block, a connecting block, a first connecting rod, a second connecting rod, a counterweight block, a limit rod, and a rolling wheel. The connecting blocks are two, which are fixedly connected with the two flanges on the valve body respectively. The upper ends of the two connecting blocks are fixedly connected with a lower supporting plate, and the lower supporting plate is fixedly connected with the spring and The upper horizontal sheet is arranged above the lower supporting sheet, which is successively connected with the spring, the supporting bar, the upper suction bar, the upper fixing block and the locking bar from left to right. The upper fixing block is an inverted V-shaped; When the valve works, the upper horizontal piece is fixedly connected with the locking rod through a fixed pin, the upper suction rod is connected with the lower electromagnetic block, and the upper fixed block is connected with the rolling wheel; The limiting rod is fixedly connected to the lower supporting plate, which is used to limit the position of the first connecting rod, the lower ends of the second connecting rod and the first connecting rod are fixedly connected to the valve rod, the rolling wheel is arranged at the upper end of the first connecting rod, and the counterweight is arranged at the upper end of the second connecting rod; The lower electromagnetic block is connected with a power supply

the invention can fixedly connect the upper part of the first linkage rod and the second linkage rod through a connecting part

when the valve is opened, the lower electromagnetic block is powered on, the lower electromagnetic block and the upper suction block are connected with each other due to electromagnetic force, and the upper fixed block is connected with the rolling wheel. At this time, the upper horizontal piece and the locking rod can be fixed together with a fixed pin; When it is necessary to realize quick cut-off control of the valve plate, take out the fixing pin. When something happens, cut off the power supply. At this time, the electromagnetism disappears. Due to the action of the spring, the upper horizontal plate is pressed down to one end of the spring with the support rod as the fulcrum, and the other end is tilted up. At this time, because the second connecting rod has a counterweight, the second connecting rod moves to one side, thereby driving the valve rod to move, making the valve plate close quickly, so as to achieve a rapid and effective cut-off of the valve

compared with the prior art, the invention realizes the rapid and effective cut-off of the valve by setting the electromagnetic control structure. In addition, the invention has simple structure and low cost, which is convenient for the application and promotion of the product in the industry

Manufacturers often manufacture according to the actual needs of users

in some specific applications, it is necessary to check the values of a Z x, J and C of the valve to perform rapid cut-off control, but there is no unified implementation standard. Therefore, how to realize the rapid and effective cut-off of the valve by one enterprise has been an important research topic in the valve field
