1. Ball valve adopts integrated structure in structure, sealing type of 4-face seat, less flange connection, high reliability, design and realization of lightweight.
2. The ball core is divided into T type and L type, with long service life, large circulation capacity and small resistance.
3, the ball valve according to the action type of single action and double action two types, single action type is characterized by once the power source failure, the ball valve will be in the control system requirements of the state.
Advantages:
1. The fluid resistance is small, and the resistance coefficient is the same as the length of the pipe section.
2. Simple structure, small size and light weight.
3. Compact and reliable, the sealing surface material of the ball valve is widely used in plastic, good sealing, and has been widely used in the vacuum system.
4. Easy to operate, fast open and close, from full open to full close only rotation 90°, convenient for remote control.
5. Easy maintenance, simple ball valve structure, sealing ring is generally active, disassembly and replacement are more convenient.
6. Wide range of applications, sizes from small to a few millimeters, large to a few meters, high vacuum or high pressure can be used.
This kind of valve is the high pressure ball valve commonly used in the existing mine. It bears high pressure and adopts u-type fast connection, which can realize rapid installation and disassembly in the daily production and use of the mine and is convenient for use.
The ash discharging ball valve is mainly used to cut off, distribute and change the flow direction of medium in the pipeline. Ash discharging ball valve can be divided into: floating ball type, fixed ball type, elastic ball type. Ash discharging ball valve is mainly used to cut off or connect the medium in the pipeline, can also be used for fluid adjustment and control, compared with other valve types, ash discharging ball valve has angular stroke output torque, open quickly, stable and reliable, widely applicable. The dust ball valve works by rotating the valve to keep the valve smooth or blocked
The structure of the electric ball valve is only composed of a few parts, which saves data consumption. Small size, light weight, small installation size electric ball valve structure diagram, small driving torque, pressure regulating valve, easy to operate, agile, just rotate 90° can be quickly open and close; And also has a good flow regulation effect and sealing characteristics, in large and medium diameter, low pressure application category, electric ball valve is the leading valve situation. When the electric ball valve is in a complete open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop through the valve is very small, so it has a good flow control characteristics. The electric ball valve has two sealing types: ball seal and metal seal. Resilient seal valve, seal ring can be embedded in the body or attached to the disc periphery. Adopt the valve of metal seal general than the valve of elastic seal long life, but it is difficult to achieve complete seal. Metal seal can adapt to higher working temperature, elastic seal has a temperature limit of the point. If the request electric ball valve is used as flow control, it is important to accurately select the size and type of valve. The construction principle of electric ball valve is especially suitable for manufacturing large diameter valve. Electric ball valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power stations. Commonly used electric ball valve has two kinds of electric ball valve and flange type. Double-head bolt is used to connect the valve between the two pipe flanges. Flange type electric ball valve is a valve with a flange, and the two ends of the valve are connected to the pipe flange with the bolt. The strength of the valve is the valve under medium pressure. Valves are mechanical products subject to internal pressure and must have sufficient strength and stiffness to ensure long-term use without breaking or deformation. Pneumatic ball valve is composed of ball valve equipped with pneumatic actuators, pneumatic actuators are divided into double-acting pneumatic actuators and single-acting pneumatic actuators, through the solenoid valve control, to achieve the ball valve switch action. Pneumatic ball valve can realize intelligent control, quickly open or close the pipeline, can effectively control and manage the pipe network.
