How to carry on the system with the right pneumatic ball Industrial Valves installation? For the pneumatic ball valve, the correct installation is not because of a lack of, so at the time of design and installation requires students to pay attention to your what? We'll get off with factory together to get to know. Superior electric cut off the metal valve seat sealing: v-type valve adopts metal valve seat, have buffet compensation function, and are excellent sealing performance and long service life. Can realize the proportional control, pneumatic regulating ball valve with two five-way solenoid valve and control box, which can realize the switch control. V-shaped ball valve core designs with special shape v-notch, with precise closure properties and control functions, suitable for control occasions. Electric explosion-proof type butterfly valve by v-shaped body and ZSQ of actuator and other accessories. Advanced control valve is a quarter-turn structure. V-shaped ball valve does not need to repair for a long time, long service life and gives you a real high efficiency to control the process conditions of a valve. before installation, should check the model according to design requirements, specifications, and according to the design drawings and the indication of the valve and the flow direction of medium pipeline, determine the direction of correct installation of the valve. 。 to be installed, packing to enrich, gasket material correctly, gland bolts should have enough margin, valve internal temporary fixing device for demolition. 。 Installed in a horizontal pipe valve stem shall be installed in the upper half above water in pipe within weeks. 。 On both sides of the valve handwheel, pneumatic ball valve should be easy to operate, can be tilted upward or horizontal installation. 。 Flanged or threaded type valve should be installed in the closed position; When the welding valve, the valve should be closed; Use socket type the valve on the socket end of the weld joint should be 0. 5 - 1. 0 mm clearance. 。 Butt welding of valve and pipeline connection weld hydrogen arc welding backing should be adopted. 。 If there are whole heat treatment of welded valve in the pipeline, should be in section of whole heat treatment after welding, weld should be local treatment. 。 drive to extend the stem and stem axis Angle should not be greater than 300, the joint should be strong, the rotation should be flexible. 。 For a thermal displacement plumbing valves, drive should have free stretch around the gap. 。 After installation of valve, operating mechanism and drive debug and test, make the reliable, flexible, instruction is correct. 。 In the installation of cast iron, ferrosilicon and enamel lined valves, should avoid connection solid or uneven body damage. 。 Horizontal line should be set on the double gate, cut-through litres of check valve, pressure reducing valve and steam trap. 。 Pneumatic ball valve should be installed in a vertical tube pipe, outlet pipe must be fixed firmly, guarantee the body vertical pneumatic ball valve. 。 Single gate valves and swing check valve should be installed in a horizontal pipe or vertical or inclined tube. 。 When handling and storage of valve, should pay attention to protect the handwheel from the collision and impact. 。 Lifting the valve is strictly forbidden on the handwheel or handle tied rope buckle. 。 Large valve before installation, should be installed ahead of bearing bracket, the weight of the valves shall not be attached on the equipment or pipeline. 。 Pipeline system in operation should timely adjust the piping system need to adjust the pneumatic ball valve, adjust SH/T3517 - requirements should comply with the relevant regulations 2001 ( Petrochemical steel pipeline engineering construction technology standard) 。 。 Adjustment, users and relevant departments should be on site supervise and confirm and seal, then complete pneumatic ball valve testing record in the end. 。 Therefore, when in the process of installation of pneumatic valves, need to pay attention to these details, so that pneumatic valve installed correctly, ensure to use in the production process.
