Description

Corrosion-resistant gate valve Technical Field The invention relates to the field of valves, in particular to a corrosion-resistant gate valve. Background Gate valves are currently the most important type of valves and are widely used for the circulation and stopping of liquid, gas, dust and other media. Most of the existing gate valves control medium circulation and stop through up-and-down movement of a gate plate, but cannot control throughput. Therefore, it is necessary to design a controlled amount of corrosion resistant gate valve. Disclosure of Invention The invention aims to solve the technical problems that most of the existing gate valves control medium circulation and stop through up-and-down movement of a gate plate, but cannot control throughput. In order to solve the technical problems, the technical scheme is that the corrosion-resistant gate valve comprises a valve body with a hollow inside and a through top and bottom, a rotating shaft A is arranged in the valve body, valve clacks are fixedly clamped on the surface of the rotating shaft A, sealing plates are arranged on two sides of the valve body, the rotating shaft A is rotationally connected with the sealing plates, and the valve clacks are attached to the inner wall of the valve body. One side fixedly connected with frame plate of valve body, the lateral wall fixed mounting of frame plate has the motor, the output shaft fixedly connected with pivot B of motor, main gear is installed to pivot B's the other end, from the gear is installed to pivot A's one end, be connected with the chain between main gear and the from the gear. One side of the frame plate is fixedly provided with a protective shell A, the outer side of the protective shell A is fixedly provided with a protective shell B, the rotating shaft B transversely penetrates through the protective shell A, and the protective shell B covers the periphery of the chain. The motor is characterized in that a voltage control box is arranged on one side of the motor and is electrically connected with the motor, and the voltage control box is used for controlling the rotation rate of the motor. And a sealing soft plate is arranged at one end of the valve clack, which is contacted with the valve body. Grooves are formed in shaft bodies of the rotating shaft B and the rotating shaft A, openings matched with the grooves are formed in inner sides of the master gear and the slave gear, and the gate valve further comprises a plug post. The frame plate is connected with the motor in a bolt connection mode. The beneficial effects of the invention are as follows: The valve body is fixedly arranged at the upper end and the lower end of the valve body through the rotating shaft, the chain and the inserted post, when the rotating shaft A does not rotate, the valve clack does not rotate, when the rotating shaft A rotates, the valve clack rotates along with the rotating shaft, media are conveyed to the other end from one end of the valve body, the rotating speed of the rotating shaft A can control the throughput of the media, the effect of controlling quantity is achieved, the motor is started, the motor drives the rotating shaft B to rotate, and then drives the main gear to rotate, the chain is connected with the main gear and the driven gear, the driven gear is rotated along with the rotating shaft A, so that the gate valve is started, the protective shell A and the protective shell B are combined, the rotating shaft B, the main gear, the rotating shaft A, the driven gear and the chain are protected, dust and other impurities are prevented from falling on the parts, the influence is caused during transmission, the rotating speed of the motor directly influences the rotating shaft A, the voltage control box can control the rotating speed of the motor through voltage regulation, the sealing soft plate directly contacts with the inner wall of the valve body, the sealing soft plate is better, the media can be prevented from leaking out during sealing, the gate valve is matched with the groove and the size of the inserted post, the main gear is penetrated into the main gear, the groove is opposite to the gap, and then the main gear is detached, and the main gear is fixed, and the inserted post can be detached.
