Process Content of Daily Protection and Maintenance of Pneumatic Ball Valve

This article is aboutPneumatic ball valveWe can know the daily protection and maintenance together with Wuxi Xinming automatic control valve industry co., ltd.Pneumatic ball valveof common sense.
Pneumatic ball valve relies on rotating spool to dredge or block the valve. in various industries. Long time use of pneumatic ball valve may be natural wear, and then lead to defects. Regular protection can reduce the frequency of defects, extend the use of life, down the user to use the cost.
Single-acting valve: normally open (normally open, closed ventilation, reset spring reset); Double effect of pneumatic ball valve: keep reset pneumatic ball valve and pneumatic implementation arrangement when opening ventilation and closing air source defects. The implementation speed of the implementation arrangement is relatively fast, and the switching speed is 0.05 seconds/time, so it is generally called pneumatic fast blocking ball valve. The switch of the valve can be controlled in the control room, without the need to run to the scene or the risk of manual control, to a large extent, save human resources, save time.
Only the pneumatic ball valve uses the pneumatic actuator to rotate 90 degrees with the air source, and the rolling torque is small. All equal body cavity for the medium to provide little resistance. Direct flow. It is generally thought that the ball valve is suitable for direct opening and closing. The utility model is primarily characterized by its compact structure, easy operation protection, can be used for water. Solvents. Acid and natural gas and other general operating medium, can also be used in harsh environment oxygen, peroxide, methane, ethylene and so on. The ball valve body can be unitary or combined.
Repair and maintenance of pneumatic ball valve:
1. Purpose: the use of instructions for the flange connection end of the electric (or pneumatic) ball valve.
2. Composition: It is composed of electric (or pneumatic) actuator and ball valve body, and is connected by supporting and connecting shaft.
Apply Bundling
1) Bundling of temperature and pressure.
2) Under the operating temperature, the nameplate indicates the allowable operating pressure of the ball valve.
Selection of PTFE or RTFE material manufacturing of the seat and seal, the operating temperature should be between 150 degrees and 200 degrees. Operating temperature Check other types of seats and seals.
4) The nominal pressure rating (PN) of the cryogenic valve can indicate the operating pressure of the valve under normal temperature conditions
5) electric or pneumatic actuators should be careful of the problem see the corresponding instructions.

equipment pneumatic ball valve:
1) Take out the protective caps at both ends of the flange and flush them when the valve is fully opened.
2) Before the equipment, the whole machine test should be carried out according to the regular signal (electricity or gas)

equipment pneumatic ball valve:
1) Take out the protective caps at both ends of the flange and flush them when the valve is fully opened.
2) Before the equipment, the whole machine test shall be carried out according to the regular signal (electricity or gas) (to avoid vibration due to transportation), and the equipment shall be connected after passing the test (wiring shall be in accordance with the circuit diagram of the electric actuator).
3) Before connecting the pipeline, it is necessary to clean and remove the remaining impurities in the clean pipeline (this may damage the valve seat and ball).
4) During the equipment process, do not use the actuator parts of the valve as a lifting point to avoid damage to the actuator and accessories.
5) valves should be horizontal or vertical equipment in the pipeline.
6) After connecting the pipelines, connect the flange pieces together with the specified torque.
Operation and application of pneumatic ball valve:
1) Before operation, it is necessary to admit that the pipes and valves have been flushed.
2) The operation of the valve is completed by driving the valve stem to rotate according to the input signal of the actuator: 1/4 turn (90) forward 1/4 turn, and the valve is closed. When 1/4 turn reverse rotation (90 °), the valve opens.
3) When the arrow indicating the direction of the implement is parallel to the pipeline, the valve is in the open state; when the arrow is perpendicular to the pipeline, the valve is in the closed state.
