In the wet alarm valve usually kept under working condition, alarm test ball valve state usually is closed or open?Because the alarm performance test on the pressure switch and hydraulic alarm, can be tested by open test ball valve, the bar working condition, the valve is closed or open? If so, if there is a police situation, if the police? If it does, it doesn't always call the police Seek expert advice.
- Should be normally closed, the test valve is only the experimental pressure switch and hydraulic alarm, water from the valve directly into the alarm line, the wet alarm valve does not move, but you open, it usually has been ringings
Is the ball valve ball valve?
- Therefore, strictly speaking, eccentric hemisphere valve ball valve, butterfly valve is more like a ball valve.s
Under what circumstances with the butterfly valve, under what circumstances with the ball valve?
- The flow control accuracy requirements are not high, the fluid pressure is small place with butterfly valve, butterfly valve is the simplest kind of valve, mainly used in regulating the air flow and powder flow!According to the pressure of the liquid and gas fluid control, flow effect, rapid opening and can completely cut off for flow with the ball!s
How many points of the ball valve, corresponding to a bit valve?
- No detailed conversion forms are required. How many inches is the representation of inches?.In English, 12 inches are 1 feet, 1 inches =8 cents.So: 1/2 "ball valve, =4 sub ball valve, 1/4" ball valve, =2 sub ball valve, 3/8 ball valve, =3 sub ball valve, and so on.Just a simple conversion relationship.s
What's the difference between T ball valve and L ball valve?
- This is the code for the three way ball valve and the three way plug valve flow passage. The L shape can only connect the two channels perpendicular to each other, and the T shape allows the three channels to communicate with each other or to connect two of them.s
The difference between cut-off valve and ball valve in PPR
- The PPR valve is plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Stem movement in the form of lifting rod (stem lifting, hand wheel not lifting), but also lifting, rotating rod type (hand wheel with the valve stem to rotate up and down, nut on the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.Ball valve has compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide methane and ethylene, etc., are widely used in various industries. Ball valve body can be integrated, or can be combination.s
