Application and advantages of Wafer Butterfly Valve With Pneumatic Actuator
Wafer butterfly valve application
Wafer Butterfly Valve With Pneumatic Actuator are widely used in gas pipelines in the sulfuric acid industry: the inlet and outlet of the blower in front of the furnace, the inlet and outlet of the relay fan, the electric demisting series and connection valves, the inlet and outlet of the blower, the adjustment of the converter, the inlet and outlet of the preheater, etc., and the use of cut-off gas. It is used in the sulfur burning, conversion and dry absorption sections of the sulfur-burning sulphuric acid plant. It is the preferred brand of valves for the sulphur-burning sulphuric acid plant. It is regarded by the majority of users as: good sealing performance, light operation, secondary corrosion, high temperature resistance, convenient operation, The flexible, safe and reliable butterfly valve makes a large number of popularization and use.
Wafer Butterfly Valve With Pneumatic Actuator are also widely used in: chemical, petrochemical, smelting, medicine, food and other industries, steam, air, gas, ammonia, oil, water, salt water, lye, sea water, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid, etc. The medium pipeline is used as a regulating and intercepting device.
Advantages of Wafer Butterfly Valve With Pneumatic Actuator
1. The unique design of three-way eccentricity enables frictionless transmission between the sealing surfaces and prolongs the service life of the valve.
2. Elastic seal is produced by torque.
3. The clever wedge-shaped design makes the valve have the function of automatic sealing as the valve is closed and tighter, and the sealing surface has compensatory and zero leakage.
4. Small size, light weight, light operation and easy installation.
5. Pneumatic, electric, hydraulic and manual devices can be configured according to user requirements to meet the needs of remote control and program control.
6. The material of replacement parts can be applied to various media, and can be lining anti-corrosion
7. Diversified continuous structure: butt clamp, flange, butt welding.
Installation introduction of Wafer Butterfly Valve With Pneumatic Actuator
1. Preparation before installation
1. Check whether the specifications and materials of the butterfly valve conform to the design before installation.
2. Before installation, clean up the internal sand, dust, foreign matter and debris to avoid irregular movement or leakage.
3. The related piping should be properly suspended and fixed according to regulations before installation to avoid improper stress on the valve after installation.
4. The two flange faces of the piping must be aligned parallel and concentric.
5. There is no need to install a gasket between the butterfly valve and the flange during installation.
6. Where the butterfly valve is close to the check valve or the pump, use a divergent joint between the two so that the valve disc will not be hindered from turning off.
2. Installation steps:
1. Open the valve disc 10 degrees before installation.
2. Set auxiliary screws at appropriate positions to adjust the distance between the two flange surfaces.
3. Insert the butterfly valve without touching the two flange surfaces and at the same time penetrate the remaining bolts.
4. After confirming that the center of the butterfly valve is concentric with the flange center and the switch position of the valve disc is not the inner diameter of the flange or the adjacent parts are obstructed, the bolts are locked repeatedly in a diagonal and gradual manner until the flange surface touches the end surface of the valve body.
5. After the installation is completed, the degree of fully open and fully closed should be confirmed again.
3. Operation:
1. Before starting the operation, use air spray to remove foreign objects on the piping, and clean the inner surface of the piping with clean water.
2. Open the valve and check the angle indicator plate to avoid torsion exceeding the opening width, and the closing position cannot be exceeded.
3. The operation of the switch is completely based on the indicator. If other hand tools are applied, the angle indicating plate and the switch will be damaged.
4. When the pressure test of piping is to be done, the valve should be opened.
5. After piping, the valve is in a fully closed state for a long time, and it should be switched once or twice a month to avoid fixation.
