Product introduction
The imported floating ball valve produced by Breer can be driven manually, electrically, pneumatically, hydraulically, and flanged, wafer type, welded, threaded, ferrule, etc., and the floating ball and fixed ball can be used as the structure. Elastic ball, sealing structure can choose PTFE, PPL, hard seal, O-ring, pressure range PN1.0MPa-32MPa, nominal diameter is DN15-300mm, material can choose WCB, stainless steel, 304,316, chromium molybdenum steel, titanium alloy Steel etc. Because the valve is used in a very wide range, the same valve has different combinations in different situations and working conditions.
Product Details
The imported floating ball valve and the American standard ball valve are the same type of on-off valve. The difference is that the closing part is a ball. Ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Two-piece ball valve, three-piece ball valve, is a new type of valve widely used in recent years, this type of valve should generally be installed horizontally in the pipeline.
The imported floating ball valve can be divided according to the structure:
1 floating ball valve
The ball of the ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and be tightly pressed on the sealing surface at the outlet end to ensure the outlet end is sealed.
The structure of the floating ball valve is simple and the seal is good, but the load of the ball bearing the working medium is transmitted to the outlet seal ring. Therefore, it is necessary to consider whether the material of the ring ring can withstand the working load of the ball medium. This structure is widely used in medium and low pressure ball valves.
Two fixed ball valve
The ball of the ball valve is fixed and does not move after being pressed. The fixed ball valve has a floating valve seat. After the pressure of the medium, the valve seat moves, so that the sealing ring is tightly pressed on the ball to ensure the seal. Bearings are usually installed on the upper and lower shafts of the ball, and the operating torque is small, which is suitable for high pressure and large diameter valves.
In order to reduce the operating torque of the ball valve and increase the reliability of the seal, oil-sealed ball valves have appeared in recent years. The special lubricating oil is injected between the sealing surfaces to form a layer of oil film. , More suitable for high pressure large diameter ball valve.
Three elastic ball valve
The ball of the ball valve is elastic. Both the ball and the valve seat seal ring are made of metal materials. The specific pressure of the seal is very large. Depending on the pressure of the medium itself, the requirements for sealing cannot be achieved, and external forces must be applied. This valve is suitable for high temperature and high pressure media.
The elastic sphere is provided with an elastic groove at the lower end of the inner wall of the sphere to obtain elasticity. When the passage is closed, the wedge-shaped head of the valve stem is used to expand the ball and tightly press the valve seat to achieve a seal. Before turning the ball, loosen the wedge-shaped head, and the ball will then return to its original shape, so that there is a small gap between the ball and the valve seat, which can reduce the friction and operating torque of the sealing surface.
Note: In the closed state of the flange ball valve, there is still pressurized fluid inside the valve body. Before maintenance, release the line pressure and keep the valve in the open position. Before maintenance, disconnect the power or air source. Before maintenance, connect the actuator and the bracket Break away.
