F343CX worm gear sector glasses valve is also known as worm gear sector blind valve, worm wheel flap valve, worm gear sector valve, by left valve body, middle valve body, right valve body, fan blind plate, screw nut, stainless steel compensator, two worm gear transmission mechanism and other components. It is connected by three screw rods, and three valve bodies are respectively fixed on the base to form a rigid structure. The middle valve body and the right valve body are connected with stainless steel expansion pipe, the left valve body and the middle valve body are respectively connected with three screw rods with left and right trapezoidal threads, and the three screw rods are rotated forward (or backward) simultaneously, then the left and the middle valve bodies are compressed (or separated). A blind plate is arranged in the middle of the three screw rods, and the blind plate rotates around the axis. The following two screw rods are equipped with positioning blocks with blind plates at the same position. When the blind plates rotate, the blind plates can be prevented from drifting and the sealing rings from scratching. One of the screw rods is equipped with a worm gear transmission mechanism to loosen the clamping valve body.

Operation methods and matters needing attention

1. Use the wrench to turn three connecting screw counterclockwise in turn, so that the valve body and the gate are separated and balanced, with an appropriate amount of clearance (about 16 mm). After confirmation, the gate is rotated to the working position, and the screw is connected by reverse rotation, so that the gate is in close contact with the valve body to achieve the purpose of absolute sealing.

2. The rubber sealing ring must not be adhered to the valve body or hard friction, in order to prevent damage to the rubber sealing ring, damaging the working performance of the valve.

3. When the left and right valve bodies are loosened, the medium will overflow. To ensure safety, the gas butterfly valve in front of the glasses valve should be closed, and ventilation and other measures should be taken to ensure safety.
