The main structural function of the ball valve and the characteristics of fireproof and antistatic

Full diameter and reduced diameter structure of ball valve
FULL&REDUCE BORE
In order to meet the different needs of customers, the ball valve has two series of full diameter and reduced diameter. The inner diameter of the full-bore ball valve is the same as the inner diameter of the pipeline, which not only minimizes fluid resistance, but also facilitates pipeline cleaning. The fluid resistance of the reduced diameter ball valve is much lower than that of the same diameter stop valve, and the weight is about 30% lighter than the ball valve of the same diameter, which effectively reduces the production cost and price, and thus has been widely used.
In order to meet different needs of customers,we provide two serries of ball valves ,full bore and reduced bore ball valve .The channel inner diameter of full bore ball valves is consistent with the inner diameter of pipeline,which can not only minimize the fluid The resistance resistance is also facilitated pipeline cleaning. The fluid resistance of necked bore ball valves is much less than that of the globe valve with the same caliber while its weight is 30% lighter than ball valve with the same caliber .As result ,it can Both the production cost and price , and is relatively widely uesd.

Valve stem anti-shooting and effective sealing structure
BLOW-OUT PROOF STEM
The valve stem adopts a bottom-mounted anti-back seal structure with a gasket. The sealing force of the inverted seal increases with the pressure of the valve medium, thereby ensuring the sealing effect of the valve stem. When the valve chamber is abnormally boosted, the valve stem will not be flushed out. The packing adopts a well-designed V-shaped structure, which can effectively convert the medium pressure inside the valve chamber and the locking force of the external gland into the sealing force of the valve stem. The fore of inverted sealing struct willincrease while the medium pressure in the valve cavity increasing of the valve cavity increases to ensure the sealing effect of the stem. The valve cavity, the stem won't be impacted out . The filler is designed with proper V-shaped structure, which can effectively conver the medium pressure inside the valve cavity and the locking force of outer gland into the sealing force of stem.

Ball valve refractory structure
FIRE SAFE SEAT SEALING
According to the needs of users, the ball valve can be designed as a refractory structure. When the fire seals out the seal ring, the sealing parts of the ball valve can form a metal-to-metal hard seal structure, effectively preventing the diffusion of the medium and preventing the fire from expanding. .
According to the user's requirement, the ball valve can be designed with fire-resistant stucture.In case of a fire and the sealing ring is damaged,every sealing part of the ball valve can form the structure of metal-to-metal hard seal, Which can prevent the spreading of both the media and fire.

Ball valve with lock structure
INTERLOCKING DEVICE
For valves installed in the field or to prevent misoperation by non-workers, and in some occasions where the vibration is large, the handle is subject to impact and misoperation. There is no locking hole in the fully open or fully closed position of the valve. Lock, play a role of security insurance.
For valve installed outdoor,thope preventing improper operation of non-workers and valves, of which collision of its stem in relatively violent vibration occasions easily causes improper operation, a locking bore can be set in the fully open position or fully closed position and a lock Can be used if needed, for the purpose of security insurance.

Ball valve anti-static structure
ANTI-STATIC DEVICE
According to the needs of users, the ball valve can be designed with anti-static structure, that is, a conductive spring is arranged between the ball and the valve stem, the valve stem and the valve body, so that the static electricity generated by the valve during the opening process passes through the set electrostatic channel. The road is introduced into the ground to achieve the purpose of removing static electricity. Avoid static ignition and ignite flammable media to ensure system safety.
According to the user's requirement, the ball valve can be designed with anti-static structure;namely,fix the conductive spring between the ball and stem as well as stem and valve body,to enable the static generated when opening the valve to be transmitted to The pipeline through static channel and conducted underground and finally eliminate the static. It can prevent the static ignition form lighting the medium to ensure safety of the system.
