1. Bypass valve: the ball valve is usually opened by standing water, so the bypass valve shall be leveled first, that is, filled with water on both sides;
2. Air valve: when water is filled, remove air and use buoy to close the valve by itself;When draining water, add air, float down by itself;
3. Pressure relief valve: when opening and closing the valve, remove the pressure water between the valve and the sealing cover to avoid wearing the sealing cover;
4. Blowdown valve: discharge the sewage from the lower part of the ball shell.

Ball valves are: floating ball valve, fixed ball valve, track ball valve, v-type ball valve, three-way ball valve, stainless steel ball
Floating ball valve
Floating ball valve
Valve, cast steel ball valve, forging steel ball valve, dust discharge ball valve, sulfur resistance ball valve, pneumatic ball valve, electric ball valve, card sleeve ball valve, welding ball valve.
According to shell/body material classification, ball valve can be divided into:
1. Metal material valve: such as carbon steel valve, alloy steel valve, stainless steel valve, cast iron valve, titanium alloy valve, monel valve, copper alloy valve, aluminum alloy valve, lead alloy valve, etc.
2. Metal body lining valve: such as lined with rubber valve, lined with fluorine valve, lined with lead valve, lined with plastic valve, lined with enamel valve.
3. Non-metallic valve: such as ceramic valve, glass valve, plastic valve.
Domestic production of ball valve manufacturers more, the connection size is also mostly not unified.It mainly falls into the following categories:
Ball valve ball is floating, under the pressure of the medium, the ball can produce a certain displacement and pressure on the sealing surface of the exit end, to ensure the exit end is sealed.
Good sealing, but the ball bears the load of the working medium all passed to the outlet seal ring, so consider whether the sealing ring material can withstand the working load of the ball medium, in the case of higher pressure impact, the ball may be offset.This structure is generally used for low and medium pressure ball valves.
Valve fixing ball valve
Valve fixing ball valve
The ball valve is fixed and does not move under pressure.Fixed ball ball valve with floating seat, by the media pressure, seat generation movement, make the sealing ring tight pressure on the ball, to ensure the sealing.Bearings are usually mounted on the upper and lower shafts of the ball, with small operation torque, 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, the oil seal ball valve also appeared, not only between the sealing surface pressure injection of special lubricating oil, in order to form a layer of oil film, not only enhance the sealing, but also reduce the operating torque, more suitable for high pressure large diameter ball valve.
The ball valve is elastic.The ball and the valve seat sealing ring are made of metal material, the sealing pressure is very big, depends on the medium itself
V-shaped ball valve
V-type ball valve (2 sheets)
Pressure has not reached the requirements of sealing, external force must be applied.This valve is suitable for high temperature and high pressure media.
Elastic sphere is to open an elastic groove at the lower end of the inner wall of the sphere to obtain elasticity.When the channel is closed, use the stem wedge to swell the ball and press against the seat to seal.Loosen the wedge head before turning the ball, and the ball returns to its original shape, leaving a small gap between the ball and the seat, reducing friction and operating torque on the sealing surface.
Type V regulating ball valve Qv347, Qv647, Qv947
Qv347, Qv647, Qv947 v-type regulating ball valve, because the ball core has v-type structure, has shearing effect on the valve seat.Therefore, it is suitable for the control of relevant technological parameters in suspension medium containing fiber or tiny solid particles in papermaking, chemical industry, metallurgy and other industrial enterprises, especially for the automatic regulation of pulp, white water, black liquid, white liquid and other suspended particle fluid and thick and muddy liquid fluid medium in pulp making and papermaking production.
This v-type ball valve is a fixed ball valve, is also a single seat sealing ball valve, the regulating performance is the best ball valve, flow characteristics are equal percentage, adjustable ratio up to 100:1.It has shear action between the v-notch and the metal valve seat, especially suitable for medium containing fiber, tiny solid particle, slurry and so on
Three - way ball valves are T and L - type.T - shape can make three orthogonal pipelines connected with each other and cut off the third channel, play the role of shunt, confluence.The l-type can only connect two orthogonal pipes, and cannot keep the third pipe connected to each other at the same time.
