Mining Ball Valves Factory Introduces The Installation Knowledge Of Ball Valves 2022-5-12 Mining Ball Valves Factory introduces the installation and disassembly instructions of hydraulic high pressure ball valves: Ball valve installation instructions: 1) Not limited by the installation direction, the flow direction of the medium can be arbitrary. 2) Leave room for the valve handle to rotate. 3) The ball valve with transmission mechanism should be installed upright. 4) High-pressure ball valves and hard-sealed ball valves have installation direction requirements. If the direction is incorrect, there will be internal leakage. Ball valve disassembly instructions: 1) Keep the valve in the half-open position, flush and remove the dangerous substances that may exist inside and outside the valve body. 2) Close the ball valve, remove the connecting bolts and nuts on both flanges, and then completely remove the valve from the pipeline. 3) Disassemble the drive device in sequence - handle, positioning plate snap ring, positioning plate, gland, remove the body cover connecting bolts and nuts, and remove the valve cover. 4) Separate from the valve body and remove the bonnet gasket. Make sure the ball is in the "closed" position, which will allow it to be easily removed from the body and then the seat. Gently push the valve stem (4) down through the hole in the valve body until it is completely removed, then take out the O-ring and the packing under the valve stem. 5) Note: Please operate carefully to avoid scratching the surface of the valve stem and the sealing part of the valve body stuffing box.

One-way Check Valve Manufacturers Introduce The Troubleshooting Process Of The Cylinder 2022-4-7 One-way check valve Manufacturers introduce the failure causes and countermeasures of the cylinder: common error 1) The limit bolt of the actuator falls off, causing the cylinder to leak air, causing the valve to fail to move or move slowly, failing to reach the predetermined opening. 2) The damage to the O-ring of the cylinder leads to air leakage, which causes the valve to operate difficult or unable to operate. 3) The deformation of the cylinder piston leads to an increase in the friction force, and the loosening of the cylinder bolts causes the cylinder to leak air, which makes the valve difficult to operate. 4) The linkage mechanism that the cylinder drives the valve body to move is loose or rusted, which makes the valve difficult to move. 5) The cylinder capacity is too small or the cylinder spring is faulty, which makes the valve difficult to operate. Cause countermeasures 1) The cause of leakage at the piston seal is that the cylinder has poor finish; the assembly sealing of the piston ring is not enough, the use temperature of the seal ring is too high, and the seal is damaged for a long time. Troubleshooting method: grind the cylinder and re-adjust the cylinder limit bolt, and re-select the seal according to the operating temperature ring, it should be installed correctly when replacing. 2) How to deal with the loosening of the cylinder limit bolts: Re-tighten the bolts. 3) The treatment method for the large friction force of the piston: re-apply lubricating oil, re-clean and grind the cylinder and piston. 4) The valve is difficult to move and cannot reach the fixed stroke, the spring of the actuator is not set enough or the spring is damaged, and the position of the limit block is inaccurate. Processing method: calibration, readjustment, spring replacement.

2 Way Ball Valves/3 Way Ball Valves Factory Introduces The Use Of Pneumatic Ball Valves 2022-3-24 Pneumatic ball valves are mainly used in pipelines to cut off fast, distribute and change the flow direction of the medium. Pneumatic ball valve is a new type of valve that has been widely used in recent years. 2 Way Ball Valves/3 Way Ball Valves Factory introduces that pneumatic ball valve has the following advantages: 1. The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length. 2. Simple structure, small size and light weight. 3. Tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastic, which has good sealing performance, and has also been widely used in vacuum systems. 4. Easy to operate, open and close quickly, just rotate 90° from fully open to fully closed, which is convenient for long-distance control. 5. The maintenance is convenient, the pneumatic ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace. 6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through. 7. Wide range of applications, diameters ranging from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure. 8. Because the power source of the pneumatic ball valve is gas, the pressure is generally 0.2-0.8MPa, which is relatively safe. If the pneumatic ball valve leaks, compared with hydraulic and electric, the gas can be discharged directly, which does not pollute the environment and has high safety. 9. Compared with manual and turbine rotating ball valves, pneumatic ball valves can be configured with large diameters (manual and turbine rotating ball valves are generally below DN300 diameter, and pneumatic ball valves can currently reach DN1200 diameter.)

Check Valve Factory Introduces The Use Of Valves Check Valves Factory introduces the selection basis of valves: 1. The purpose of the selected valve, the operating conditions and the control method. 2. The nature of the working medium: working pressure, working temperature, corrosive properties, whether it contains solid particles, whether the medium is toxic, whether it is a flammable or explosive medium, the viscosity of the medium, etc. 3. Requirements for valve fluid characteristics: flow resistance, discharge capacity, flow characteristics, sealing level, etc. 4. Installation size and external size requirements: nominal diameter, connection method and connection size with the pipeline, external size or weight limit, etc. 5. Additional requirements for valve product reliability, service life and explosion-proof performance of electric devices. (Note when selecting parameters: If the valve is to be used for control purposes, the following additional parameters must be determined: method of operation, maximum and minimum flow requirements, pressure drop for normal flow, pressure drop at closing, maximum and minimum inlet to the valve pressure.)

How Mining Ball Valves Company Introduces Ball Valves Mining Ball Valves Company introduces the characteristics of ball valves 1. Has the lowest flow resistance. 2. It will not get stuck when working without lubricant, so it can be reliably applied to corrosive media and low boiling point liquids. 3. It can achieve 100% sealing in a large pressure and temperature range. 4. It can realize ultra-fast opening and closing, and the opening and closing time of some structures is only 0.05~0.1s, so as to ensure that it can be used in the automation system of the test bench. When the valve is opened and closed quickly, there is no shock in operation. 5. The spherical closure can be automatically positioned in position. 6. The working medium is reliably sealed on both sides. 7. When fully open and fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface. 8. With compact structure and light weight, it can be considered as the most reasonable valve structure suitable for low temperature medium system. 9. The valve body is symmetrical, especially when the valve body structure is welded, which can well withstand the stress from the pipeline. 10. The closing piece can withstand the high pressure difference when closing. 11. The ball valve with fully welded valve body can be directly buried in the ground, so that the valve internals will not be corroded, and the maximum service life can reach 30 years. It is the most ideal valve for oil and natural gas pipelines. https://www.hydraulicballvalve.net/
