I. Overview of Butt Welding Butterfly Valve

的蝶板安装于管道的直径方向。 The butterfly plate of the butt welding butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, the rotation angle is between 0 -90 , and when it is rotated to 90 , the valve is fully opened.
Valves with metal seals generally have a longer life than valves with elastic seals, but it is difficult to achieve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals have the disadvantage of being temperature limited.
If butterfly valves are required for flow control, the main thing is to choose the correct valve size and type. The structural principle of the butterfly valve is particularly suitable for making large-caliber valves. Butterfly valves are widely used not only in general industries such as petroleum, gas, chemical, and water treatment, but also in cooling water systems in thermal power stations.
法兰式蝶阀 两种。 Commonly used butterfly valves are wafer butterfly valves and flange butterfly valves . 气动法兰式伸缩蝶阀 是阀门上带有法兰,用螺栓将阀门上两端法兰连接在管道法兰上。 Wafer type butterfly valve uses double-headed bolts to connect the valve between the two pipe flanges. Pneumatic flange type telescopic butterfly valves have flanges on the valve, and bolts are used to connect the two ends of the valve to the pipe flange.
 

Features of Butt Welding Butterfly Valve

Its main features are as follows:
1.Compact structure, small size, light weight, flexible operation, easy to use;
2. It adopts three-dimensional eccentric elastic or multi-level hard sealing structure, and its sealing performance reliably reaches zero leakage;
3. This valve cannot be blue, which brings great convenience and beautiful appearance to the pipe and insulation bandaging;
4, with high temperature, high pressure, corrosion resistance, wear resistance and other characteristics.
Transmission type: worm drive, pneumatic drive, electric drive.

3. Butt welding butterfly valve adopts standard

Welding size: GB1224; ANSI B16.25; DIN2559
Structure length: GB / T12221-1989; API609
Pressure test: GB / T13927-1992; API598

Performance comparison of butterfly valve and gate valve

Which of the ordinary butterfly valve and gate valve with the same nominal pressure and nominal diameter is more tight and not easy to leak?
Gate valve is better than the butterfly valve, but there are manufacturers of butterfly valve sealing performance is good.
The gate valve is large and takes up a lot of space.
The butterfly valve is small in size and takes up little space.
When selecting specifically, also consider the temperature of the medium, the seal and packing of the valve.
The regulations stipulate that disc valves with a nominal diameter greater than 50 are used.
Butt-welding butterfly valve is a national key new product. The high-performance manual butterfly valve adopts a double eccentric and a special oblique cone oval seal structure. The traditional eccentric butterfly valve solves the disadvantage that the sealing surface is still in sliding contact friction when opening and closing 0 ~ 10 , and realizes the effect that the sealing plate is separated at the instant of opening, and the contact is sealed at the moment of contact. Good purpose.

Five, butt welding butterfly valve structural characteristics

① The unique design of the three-way eccentricity makes frictionless transmission between the sealing surfaces and prolongs the service life of the valve.
② An elastic seal is generated by torque.
③ The clever wedge-shaped design makes the valve have an automatic sealing function as it closes and becomes tighter, with compensating and zero leakage between the sealing surfaces.
④ Small size, light weight, light operation and easy installation.
⑤ Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
⑥ Replacement parts can be applied to various media, and can be lined with anticorrosion (lined with F46, GXPP, PO, etc.).
⑦Continuous structure diversification: butt clamp, flange, butt welding.

Six, butt welding butterfly valve structure and use

Used for gas pipelines in the sulfuric acid industry: front and rear blower inlets and outlets, relay blower inlets and outlets, electric defogging tandem and connection valves, S02 main blower inlets and outlets, converter adjustment, preheater inlet and outlet adjustments and cutoff gas usage.
It is used in the sulfur incineration, conversion and dry suction section of the sulfuric acid plant. It is the first choice brand of valves for sulfur acid plant. It is considered by the majority of users as: good sealing performance, light operation, side corrosion, high temperature resistance, easy operation, Flexible, safe and reliable butterfly valves have been widely used.

It is also widely used in chemical, petrochemical, smelting, medicine, food and other industries. It is used as a regulating and shut-off device on the pipeline of equal media.
