Description

The invention belongs to the technical field of valve control, and in particular relates to a valve with electromagnetic quick cut control.

Background of the invention

The valve is a control component in the fluid delivery system. It has functions of cut-off, regulation, diversion, anti-backflow, pressure regulation, split or overflow pressure relief. The valve can be used to control air, water, steam, various corrosive media, mud. The flow of various types of fluids such as oils, liquid metals and radioactive media.

Valves for fluid control systems, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems, are available in a wide variety of sizes and specifications. There is no uniform production and use standards. Manufacturers often follow the actual needs of users. Manufacturing.

In some specific applications, it is necessary to achieve rapid shut-off control of the valve, but there is no uniform implementation standard. Therefore, how to realize the rapid and effective cutting of the valve is an important subject that has been studied in the valve field.

Summary of the invention

SUMMARY OF THE INVENTION The object of the present invention is to provide a valve with electromagnetic quick cut control to achieve a quick and effective shutoff of the valve to meet the user's needs.

In order to achieve the object of the present invention, the present invention provides a valve with electromagnetic quick cut control, the valve including a valve body and a control portion, the valve body portion including a valve body and a valve stem; the control portion including a spring, an upper portion Horizontal piece, support rod, upper suction rod, upper fixed block, lock rod, lower support piece, lower electromagnetic block, connecting block, first linkage rod, second linkage rod, counterweight block, limit rod, rolling wheel The two connecting blocks are fixedly connected to the two flanges on the valve body, and the upper ends of the two connecting blocks are fixedly connected with a lower supporting piece, and the lower supporting piece is fixed from left to right. Connecting the spring, the support rod, the lower electromagnetic block and the locking rod, the upper horizontal piece is disposed above the lower supporting piece, and the spring, the supporting rod, the upper suction rod and the upper fixing are sequentially connected from left to right a block, a locking rod, the upper fixing block is an inverted V-shaped; when the valve is in operation, the upper horizontal piece and the locking rod are fixedly connected by a fixing pin, and the upper suction rod is connected with the lower electromagnetic block, The fixing block is connected to the rolling wheel; the limiting rod is fixedly connected Connected to the lower support piece for defining a position of the first linkage rod, and the lower end of the second linkage rod and the first linkage rod are fixedly coupled to the valve rod, the scroll wheel The weight is disposed at an upper end of the first linkage rod, the weight is disposed at an upper end of the second linkage rod; and the lower electromagnetic block is connected to a power source.

According to the invention, the first linkage rod and the upper portion of the second linkage rod are fixedly connected by the connecting member.

When the valve is opened, the lower electromagnetic block is energized, and the lower electromagnetic block and the upper suction block are connected to each other by 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 by using the fixing pin. Together; when the valve disc is required to achieve rapid shut-off control, the fixing pin is taken out. When there is a situation, the power is cut off. At this time, the electromagnetic force disappears. Due to the action of the spring, the upper horizontal piece is pressed toward the spring end with the support rod as a fulcrum, and the other end is tilted up. At this time, since the second linkage rod has a match The weight, therefore, the second linkage rod moves to one side, thereby driving the valve stem to move, so that the valve plate is quickly closed, thereby achieving a quick and effective cutting of the valve.

Compared with the prior art, the invention realizes the rapid and effective cutting of the valve by setting the electromagnetic control structure, and further realizes the simple structure and low cost, and is convenient for the application and promotion of the product in the industry.
