Pneumatic pipe ball valve installation method

March 06, 2023

1, the preparation before installation: (1) Pneumatic pipeline valve before and after the pipeline is ready. Before and after the pipeline should be coaxial, two flange sealing surface should be parallel. The pipe should be able to withstand the weight of the pneumatic pipe ball valve, otherwise the pipe must be equipped with appropriate support. (2) purge the pipeline before and after the pipeline clean, clear the pipeline of oil, welding slag and all other impurities. (3) check the pneumatic pipe ball valve logo, pneumatic pipe valve to find out intact. Open the valve fully closed several times to confirm its normal operation. (4) Remove the protective parts on the connecting flanges on both ends of the pneumatic pipe ball valve. (5) Check the valve hole to remove possible dirt, and then clean the valve hole. Even small particles of foreign matter between seat and ball may damage seat sealing surface. 2, installation: (1) the valve installed on the pipeline. Either end of the valve can be installed on the upstream side. The handle-actuated valve can be mounted anywhere on the pipe. However, pneumatic line ball valves with gearboxes or pneumatic drives should be mounted upright, ie mounted on a horizontal pipe with the drive above the pipe. (2) between the valve flange and pipeline flange installed according to the pipeline design requirements gasket. (3) The bolts on the flange should be symmetrical, one after another, evenly tightened. (4) Connect the pneumatic line (with pneumatic actuator). 3, the installation of the inspection: (1) Operate the drive Kai, pneumatic valve closed several times the ball valve should be flexible without astringent, confirmed its normal operation. (2) according to the pipeline design requirements on the pipe and pneumatic pipe valve flange sealing surface between the performance check.
Flexible Gate
Flexible lift gate is a flexibel soft curtain door, inside and outside the two curtains , curtains used between the aluminum beams connected with a vertically movable rail , the roof beams have levels not in the same straight line and hanger large plants in particular Be applicable , Flexible lift door installation does not take up interior space in the hole inside , When the first move to open the door , and finally superimposed over the hole , Off event curtain rail first and then fall down until its is completely closed

Door body composition :

The bottom of the door curtain rail aluminum beam beam seal top drive system and transmission of electrical control systems and safety devices

Flexible door features:

1. Light weight compared with other types of the same size door , flexible door lighter weight reduces the strength of steel at the top of the doorway architecture degree requirements ,

2. Small compared with the same specification of the machine style doors 2, footprint ,flexible installation in the door after the hole is turned on internally stacked above the hole , do not take up interior space , Large Span hole may be provided a plurality of movable rail the entire door into several independent stacking doors shorten the span of a single door so that the overall thickness of the door is reduced , further reducing the footprint

3. Rational layout flexible doors with movable rail rail can set different activities based on the specific circumstances of the door into the door several sizes of uneven accumulation of doors to make the building as a whole rational layout greatly reduces the overall architecture of the space and cost

4. The wind strength between two layers of high flexible door curtain as the bottom of an aluminum beam has a wind skeleton steel structure , By adjusting the beam thickness and spacing , which can resist wind pressure of any intensity , so the door can be flexible for use in any area

5. The tensile strength of the flexible door after door curtain is double polyester fabric , high tensile wire rope equipped with ultra-high hole suitable for large machinery such as aircraft hangars and repository

6. The curtain coated with vinyl coated with a waterproof sunscreen and smoldering performance , capable of sound absorption retardant insulation mildew proof and so on

7. Safe door , Cube with anti-lock break to ensure safety in case of accidental breakage of wire rope jammed in the door quickly experience anywhere rails , Multiple protection features mechanical and electrical installation to ensure t he safety of goods passing aircraft and other vehicles and personnel , the movable rail is also equipped with anti-fall device , you can ensure reliable parked at the top of the hole after the movable rail is raised without falling , The bottom of the door is equipped with and airbag , it will immediately rebound to rise until the safety door drops open when obstacles encountered in the process , You can also install infrared protection device on the door
