Q347FThe worm gear drive dust discharge ball valve only needs to rotate 90 degrees and a small rotating torque to close tightly. The completely equal inner cavity of the valve body provides the medium with a small resistance and a straight through channel. It is generally considered that Zui ball valve is suitable for opening and closing directly. However, in recent development, ball valve has been designed for throttling and flow control. The main characteristics of the ball valve are its compact structure, easy operation and maintenance, suitable for water, solvent, acid and natural gas and other general working media, but also suitable for the working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene. The valve body can be integral or combined.

1. The manual part can be made of steel plate or cast by stainless steel. The handle is equipped with a limit structure to set the limit at the opening and closing positions of the valve. When the valve is used on the key device, the limit block is provided with a lock hole to lock the switch position to avoid misoperation. The handle is clearly marked with opening and closing.
2. The valve rod is forged and modulated by a182f (1Cr13), and the hardness reaches hb220-250. The valve rod is connected with the handle through flat key or spline or square wedge, which has strong universality and is easy to disassemble and assemble. The valve rod is equipped with anti blowing structure.
3. The packing of the valve is braided, flexible graphite sealing ring or tetrafluorone sealing ring, which makes the valve stem reliable sealing under certain lubrication conditions.
4. According to the requirements, the ball valve can be designed as an anti-static structure, and conductive springs are set between the ball and the valve stem, and between the valve stem and the valve body, so as to avoid the ignition of flammable substances by static electricity and ensure the safety of the system.
5. The seal pairs have various forms. According to different working conditions, soft seal, hard seal, fireproof valve seat and other structures can be selected; floating ball type is below DN 150, and fixed ball form is below DN200.
6. The auxiliary sealing structure can be set at the valve seat of the ball valve, and the grease injection valve can be installed at the valve seat and the valve rod, which can be temporarily sealed in case of emergency, and the valve rod can be lengthened according to the need to be suitable for the place of buried laying.
