Ball valve is evolved from the plug valve, its opening and closing parts as a ball, using the ball to rotate 90 degrees around the axis of the stem to achieve the purpose of opening and closing, the difference is that the cock body is a ball, with a circular through hole or channel through its axis. The ratio of the sphere to the passageway should be such that when the ball is rotated 90 degrees, the inlet and outlet should be completely spherical, thus cutting off the flow.
The role of ball valve in the pipeline is mainly used to cut off, distribute and change the direction of media flow, designed into the V-shaped opening ball valve also has good flow regulation function.
Ball valve is not only simple in structure, good sealing performance, but also in a certain nominal range of small volume, light weight, less material consumption, small installation size, and driving torque is small, easy to operate, easy to realize rapid opening and closing, is one of the fastest developing valve varieties in recent decades. Especially in the United States, Japan, Germany, France, Italy, West, Britain and other industrial developed countries, ball valves are widely used, the variety and number of use is still continuing to expand, and to high temperature, high pressure, large mouth, high sealing, long life, excellent regulatory performance and a valve multifunctional direction, its reliability and other performance indicators have reached a higher level, And has partially replaced Gate Valve, Globe Valve, Regulating Valve.

Working principle of HXQM(M) series coal grinding bag type explosion-proof dust collector Filtering condition: Dust-containing flue gas vertically enters the ash hopper of the lower part of the dust collector from the inlet flue of the top, because each dust collector is equidistant from the air inlet. To the arrangement, the flue gas can enter the chambers uniformly, and the coarse particles directly fall into the ash bucket due to the inertia to form a pre-separation, and the fine particles are filtered on the inner surface of the filter bag and adsorbed on the surface of the filter bag. The flue gas passes through the filter bag and enters the bag chamber, and then flows into the air outlet pipe, which is discharged into the atmosphere by the exhaust fan.
Cleaning condition: When the dust is attached to a certain thickness on the inner surface of a certain filter bag, it will lead to an increase in system resistance. At this time, the cleaning system will start the anti-drying machine according to the set program, close the exhaust valve of the chamber, stop the filtration of the chamber, and open the anti-blowing valve of the chamber, and blow the anti-drying pipe, the anti-blowing valve and the ventilation slot. Entering the chamber, the filter bag is shrunk under the action of the back air blow (one shrink bag). HXQM (M) series coal grinding bag type explosion-proof dust collector performance characteristics: unique explosion-proof device, can completely solve the hidden danger caused by the explosion of dust-removing medium. Off-line cleaning, no secondary ash, good cleaning effect. The filter bag is self-locking and sealed, with good sealing performance and high dust removal efficiency.
HXLC (Y) cylindrical bag type dust collector is based on the summary of various series of glass fiber bag dust collectors. Through optimization design, the new cylindrical body is used, the top air inlet is introduced into the lower part through the central air duct. Evenly entering each room, the design is more reasonable, and also solves the problem of uneven air inlet in the LFFF series glass fiber bag dust collector and other glass fiber bag dust collectors. Due to the reduced center of gravity of the equipment, the equipment is easy to install, overhaul, maintain and use.
The dust collector is also equipped with new technologies such as microcomputer control and switching valve combination cleaning. The cleaning is more thorough, the degree of automation is higher, the operation is more stable, and the operating rate is higher with the host. The emission concentration of the chimney outlet is lower than the national emission standard. (50mg/Nm3). The dust collector can change the bag without stopping the compartment, and the operation is simple, safe and reliable, and is an ideal device for solving the dust removal of the furnace kiln.

HXQM(M) series coal grinding bag type explosion-proof dust collector is a new high-efficiency bag filter specially developed for coal grinding and dust removal based on the air box pulse dust collector. It has an explosion-proof mechanism and is equipped with an explosion-proof valve for the collection of pulverized coal preparation system and flammable and explosive dust.
