Introduction to the explosion-proof wave valve.

FA49H explosion-proof wave safety valve is a kind of anti-explosion.

Enguang explosion-proof wave valve.

In addition to the water hammer shock wave caused by various reasons in the pipeline, it is a device to protect the pipeline and equipment from damage. It is suitable for various water supply and drainage systems such as industrial and mining, enterprises, high-rise buildings, power stations, etc., using the expansion and contraction of the air in the upper chamber of the piston, so that the sudden shock wave can be buffered and the strength is relieved, and the equipment damage caused by the huge water hammer impulse is avoided to the greatest extent. The device has simple structure, excellent material selection and long service life.

Parameters of explosion-proof valve Nominal pressure:

Nominal diameter: 15 300

Pressure of air cavity (% of pipeline pressure) 50 70% Applicable medium: clean water and sewage without debris.

Applicable medium temperature: 0 80

Flange standard: GB T GB T 9113

Test standard: GB T 13927 API598 Installation Instructions All kinds of FA49H explosion-proof safety valves should be installed vertically.

There should be no resistance at the outlet of the FA49H explosion-proof wave safety valve to avoid pressure.

The FA49H explosion-proof wave safety valve should be specially tested before installation, and its tightness should be checked.

The FA49H explosion-proof safety valve in use should be checked regularly.

There is a coal safety explosion-proof certificate, Shanghai Huquan valve manufacturer is trustworthy and a veteran enterprise.

The valve itself is not explosion-proof, and in general, the explosion-proof valve refers to the actuators, control cabinets, and electrical components installed on the valve. Explosion-proof valves are upgraded versions of ordinary valves. It is mainly used in dangerous, flammable, explosive and other occasions.

Explosion-proof valves are used in underground coal mines or flammable and explosive occasions to bring safety and convenience to themselves and others, causing unnecessary losses.

Hello landlord.

Whether you need explosion-proof or not depends on what medium your pipeline takes, and whether there are other flammable and explosive materials on site.

According to the medium requirements of the pipeline, other electrical control components such as solenoid valves and limit switches provided by the manufacturer can reach different explosion-proof levels.

It is divided into two categories according to the environment:

Category: Underground electrical equipment in coal mines.

Category: Except for coal mines, underground all other high-quality gas environment electrical equipment.

Class can be divided into class A, B, class C, and the equipment marked B can be applied to the use conditions of equipment A; c can be applied to the conditions of use of a and b.

It is divided into 6 grades according to the ambient temperature:

**Electrical equipment for sexual environment is divided into groups T1-T6 according to their maximum surface temperature.

t1 t2 t3 t4 t5 t6

For example, natural gas pipelines have a surface temperature of up to 100

The explosion-proof level of the equipment should reach EX BT4

The explosion-proof pneumatic ball valve is composed of AT (GT) series pneumatic actuator and floating ball valve, which is suitable for adjustment and shut-off. The explosion-proof pneumatic ball valve has excellent sealing performance, large flow capacity, simple structure, long service life and easy maintenance. The actuator is simple in structure, compact, excellent in performance and large in output torque.

The explosion-proof pneumatic ball valve is equipped with an explosion-proof travel limit switch, an explosion-proof solenoid valve, a pressure reducing valve and an air source to realize the switch operation, and send out two pairs of passive contact signals to indicate the switch of the valve. Actuators are available in single-acting and double-acting models.

Depending on the working conditions you are using, you can choose a ball valve with explosion-proof certificate.

1. The explosion-proof electric ball valve is simple to operate, quick to open and close, and the servo amplifier is built-in, with high reliability. Electric ball valve European hardcover, exquisite technology, excellent quality, reliable sealing, instead of imports.

2. The explosion-proof electric ball valve has good flowability, excellent quality, exquisite and beautiful, small opening and closing torque and long life. Ball valves are widely used in high-pressure and large-diameter applications to control high-viscosity, media with fibers and fine particles.

3. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the erosion of the sealing surface of the valve will not be caused when the medium passes.

The special driving mechanism of the underground valve in the coal mine is generally composed of an explosion-proof motor, a complete set of deceleration mechanism, a protection mechanism, etc.

It is a device that is mainly used to control the direction, pressure, and flow of fluid in the drainage pipe, and is a device that makes the flow of the medium (liquid grip, gas, powder) in the pipe and equipment move or stop, and can control its flow.

The mining is generally Bu Chiqing ZB45, which is more. You must have an explosion-proof certificate and a safety certificate to use it.

Shandong Zhongmei Electric Appliance provides professional mining automatic drainage system.

The special driving mechanism of the coal mine foundation combustion spring valve is generally composed of an explosion-proof motor and a complete set of pulse reduction and speed resistance mechanism and protection mechanism.

It is a device that is mainly used to control the direction, pressure, and flow rate of the fluid in the drain pipe, and is a device that makes the flow or stop the flow of the medium (liquid, gas, powder) in the piping and equipment, and can control its flow.

The explosion-proof solenoid valve is to enclose all the parts of the equipment that may ignite the gas mixture in a shell, and the shell can withstand the flammable mixture that penetrates into the inside of the shell through any joint surface or structural gap of the shell without damage, and will not cause the ignition of the external environment formed by one or more gases or vapors, and put the parts that may produce sparks, arcs and dangerous temperatures into the flameproof shell, and the flameproof shell separates the internal space of the equipment from the surrounding environment. There is a gap in the flameproof shell, and there may be a ** gas mixture inside due to the respiration of electrical equipment and gas penetration.

The explosion-proof version has an IP68 rating

The explosion-proof level has hail change BT4

The electric device carried by the CT4 explosion-proof product source is generally more demanding, otherwise it will not meet the explosion-proof requirements.

There are generally two types of explosion-proof valves, horizontal explosion-proof valves and vertical explosion-proof valves. Both kinds of explosion-proof valves are covered with explosion-proof membrane, the vertical explosion-proof valve is installed on the cylinder, and the horizontal explosion-proof valve is installed on the top.
