Coal mine explosion-proof electric ball valve is widely used in pipelines for explosive gas or coal mine bottom excavation surface. It has stable quality and good explosion-proof performance. Our company can produce explosion-proof electric ball valve with explosion-proof voltage-based DC12V, DC18V, DC24V. Appearance, quality, and frequent use of units praise.
After the electric ball valve is pushed into the coal mine market, it has the characteristics of low cost, stable operation, convenience and high efficiency. The application of coal mine electric ball valve in mines has been widely promoted. The price of mine electric ball valves is low.
Coal mine intrinsically safe electric ball valve also has the following characteristics:
1. The fluid resistance is small, and the ball valve is the one with the smallest fluid resistance in all valves. Even if it is a reduced diameter ball valve, the fluid resistance is relatively small.
2. The thrust bearing reduces the friction torque of the valve stem, which makes the valve stem balanced and flexible in long-term operation.
3. The sealing performance of the valve seat is good, and the sealing ring made of PTFE material is used, the structure is easy to seal, and the sealing ability of the ball valve increases with the increase of the medium pressure.
4. The valve stem seal is reliable, because the valve stem only makes rotary movement without lifting movement, the packing seal of the valve stem is not easy to damage, and the sealing capacity increases with the pressure of the medium.
5. Due to the good self-lubrication of PTFE and other materials, the friction with the ball is lost and the service life of the ball valve is prolonged.
6. Bottom-mounted stems and stem heads prevent the valve stem from being ejected. If the fire damages the stem seal, metallic contact can also form between the raised steps and the valve body to ensure stem sealing.
7. Under high pressure, the electric ball valve can withstand the inlet pressure of 7Mpa.
In most cases, it is used to control the flow and flow of various fluids, such as water, oil, and chemical liquids. The parameters used are temperature, pressure, and flow rate. The control valves commonly used in factories include several types such as pressure reducing valves, pneumatic constant temperature valves, solenoid valve constant temperature systems, proportional control valve constant temperature systems, and temperature control valves. When selecting various types of automatic valves, factors such as the type of heat engine, the required precision, the quality of the control valve, pressure drop, flow rate and its structure, failure rate, manufacturer credit and after-sales service and other factors should be considered in order to achieve economical and practical purposes. The application of coal mine electric ball valve in mines has been widely promoted. The price of mine electric ball valves is low.

The explosion-proof electric ball valve in coal mines has been widely used in mines.
Electric explosion-proof ball valve is a rotary ball valve with a 90 degree rotation angle, excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, convenient maintenance, long service life, equal valve body passage and connecting pipe diameter and a diameter, medium Almost no loss can flow through. Equipped with a gear reduction mechanism to increase the torque, the product is usually used in tight sealing applications. Besides control of gas, liquid and steam media, it is also suitable for controlling sewage and containing fibrous impurities. It is widely used in coal mines, petroleum, chemical industry, natural gas, etc. Biogas, gas and other work areas. The application of coal mine electric ball valve in mines has been widely promoted. The price of mine electric ball valves is low.
