1, double blocking and discharge function: fixed trunnion valve ball with spring preload floating seat, regardless of the valve is fully open or fully closed when the upper and lower side of the valve seat to block the fluid, the valve body cavity retentate through the discharge valve discharge The2, automatic pressure relief function: the valve bo... 1, double blocking and discharge function: fixed trunnion valve ball with spring preload floating seat, regardless of the valve is fully open or fully closed when the upper and lower side of the valve seat to block the fluid, the valve body cavity retentate through the discharge valve discharge The2, automatic pressure relief function: the valve body cavity to stay in the medium temperature rise caused by abnormal boost, no need to pass the safety valve, but only by the valve seat function can automatically pressure relief, which ensure the mounting pad ball valve in the delivery of liquid media safety Sex is very important.3, fire safety structure: the valve has a fire safety function, its design, manufacture are to comply with API607 and API6FA specification requirements.

The sealing principle of ball valve seat varies according to its structure. The commonly used seat structure can be divided into fixed seat floating sphere and floating ball valve seat. When the seat fixed sphere floating ball in the direction of fluid flow under the action of a fluid pressure produce displacement, making it more closely after the valve seat seal and contact, namely in the sealing surface pressure increase, form a single seal, at the same time, before the valve seat sealing surface of the pressure decreases, often do not guarantee the seal. When the floating ball valve seat is fixed, the fluid pressure cannot cause the ball to move, but the valve seat presses the ball with the help of spring or fluid thrust to establish the sealing specific pressure.

Trunnion Top Entry Ball Valve has long been washed by the material, resulting in friction, causing severe impact wear and tear, can not meet the normal production, while causing the use of equipment shortened.

Trunnion Top Entry Ball Valve has long been washed by the material, resulting in friction, causing severe impact wear and tear, can not meet the normal production, while causing the use of equipment shortened. The current wear on the ball valve wear-resistant materials, such as ceramic materials, polymer composite materials and other methods, the application of more technical system. Polymer material has excellent adhesion performance, super wear resistance, safe solution to the metal wear and tear of the shortcomings to ensure that the normal production of enterprise equipment. And the unique ceramic material and special surface enhancer in the material to make it in the worst of the dry grinding environment wear and anti-physical impact performance is better than any steel even more than the tile, the product with the coal is not compatible with the performance is to prevent Ideal material for coal accumulation.

Good sealing, but the ball to bear the working medium of the load all passed to the export seal, so to consider whether the sealing ring material can withstand the work load of the ball medium, when subjected to higher pressure impact, the ball may be offset The This structure, generally used in 3 way L type ball valve.Ball of the ball is fixed, af... Good sealing, but the ball to bear the working medium of the load all passed to the export seal, so to consider whether the sealing ring material can withstand the work load of the ball medium, when subjected to higher pressure impact, the ball may be offset The This structure, generally used in 3 way L type ball valve.Ball of the ball is fixed, after the pressure does not produce movement. Fixed ball valve with a floating seat, by the media pressure, the valve seat movement, so that the seal on the ball to ensure that the seal. Usually with the ball on the lower shaft with bearings, operating torque is small, 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, there have been oil seal ball valve, both in the sealing surface between the injection of special lubricants to form a layer of oil film, which enhances the seal, but also reduces the operating torque, Applicable high pressure large diameter ball valve.

Metal Seat Trunning Mounted Ball Valve: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium valves, Monel valves, copper alloy valves, aluminum alloy valves, lead alloy valves.2. Metal body lining valve: such as rubber lined valve, lining fluorine valve, lining the lead valve, lining plastic valve, lining enamel valve.3. Non-metallic materials valves: such as ceramic valves, glass valves, plastic valves.Domestic production of ball valve manufacturers are more connected to the size of most are not uniform. Mainly divided into the following categories:Ball of the ball is floating, under the action of the media pressure, the ball can produce a certain displacement and pressed on the outlet side of the sealing surface to ensure that the export side of the seal.
