Q341F Worm Gear Liquefied Ball Valve Overview:

Q341F Worm Gear Liquefied Ball Valve produced and sold by Baigang valve group Closure The ball rotates around the valve body centerline to open and close a valve. The seal is embedded in the valve seat. A spring is provided at the end of the metal valve seat. When sealing When worn or burned, push the valve seat and the ball to form a metal seal under spring action. It has a unique automatic pressure relief function, when the valve cavity medium pressure exceeds the spring preload, the outlet valve seat back away from the ball, to achieve automatic relief pressure relief valve seat automatically reset for water, solvents, acids And natural gas and other general working medium, but also for poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various industries.

Q341F Worm Gear Liquefied Ball Valve structural features:

1, a unique valve seat seal seat structure 
 with the front seal design, this structure has a two-way seal and the cavity automatically relief function. The sealing seat, inlaid with a sealing material, floats and is spring-loaded. When in the closed position, the sealing surface remains in intimate contact with the ball to ensure leak-tightness of the valve at both high and low pressure drops. 
 2, automatic pressure relief structure 
 When the cavity pressure abnormal increase phenomenon, the single seal structure of the ball valve with automatic pressure relief function, and double seal structure of the valve body pressure relief device on the additional pressure relief. 
 3, sealed emergency ambulance function 
 Valve design has an auxiliary valve seat emergency seal system. Once the sealing surface is damaged, the corresponding sealant can be injected through the auxiliary sealing system for emergency treatment and the seat area can be rinsed and lubricated by the auxiliary system when necessary. 
 4, anti-static device 
 When operating the valve, due to the friction between the ball seat, will have electrostatic charge and accumulate in the ball line. In order to prevent static sparks, special anti-static devices installed in the valve, the static electricity derived. 
 5, the fire structure 
 fixed ball valve seat with a unique structure, when a fire, the non-metallic sealing surface material burned, the metal ring spring with the elasticity of pushing the valve seat seal with the sphere, thus preventing the spread of fire and media outflow. (Fireproof structure design in line with API607, JB / T6899 and BS755), 
 6, the full diameter structure and reduced diameter structure 
 To meet user needs, far a company with all-diameter series of ball valves and reduced diameter series, full diameter ball valve pipe diameter Consistent with the pipe diameter, easy to clean, etc. Diameter reduction ball valve light weight, the fluid resistance is only part of the same diameter globe valve, the prospects are broader. 
 7, the body of the discharge device 
 according to customer requirements, the ball valve body to install the drain valve. Once both ends of the valve are closed, the back pressure in the valve chamber can be vented and relieved through the valve's drain valve.
