- Q:What is the working principle of the flue check valve?
- One end of the Simon common flue check valve is connected with the air pipe of the fume exhauster, and the other end is connected with the common flue.When the lampblack machine is started with air flow through the air inlet and the smoke diversion surface, pushing the one-way valve, the oil fume discharged into public flue; when the lampblack machine stops working, one-way valve automatically closes under the action of gravity, the oil fume channel isolated from the public flue, public flue fumes will not enter in.
- Q:What is the difference between the check valve rcvx and SFCV?
- One way check valve is check valve, only for preventing all kinds of pipelines or equipment on the flow medium reverse flow one-way valve.Check valves are widely used and there are many kinds of check valves. The following are common water supply and heat check valves:1, spring: the liquid from the bottom up, rely on the pressure spring controlled valve, the pressure disappears, the spring force the valve, sealing liquid backflow. Often used in the smaller diameter check valve.2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.
- Q:Ball shaped sewage check valve pictures and working principle of the structure.
- Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
- Q:Standard and specification for stop check valves
- Design and manufacture: GB12235 structure length: GB12221Pressure temperature range: GB9131, JB/T74, HG20604Connection flange: JB/T79, GB9113, HG20592Test and test: JB/T9092, GB13927
- Q:What's the difference between a stop valve and a check valve? Is it a valve?
- The cut-off valve has the following advantages: 1. in the process of opening and closing, the friction of the sealing surface is smaller than that of the gate valve, and it is wearable. 2. high opening height. 3. usually only a sealing surface, the manufacturing process is good, easy to repair. The valve is widely used, but because the opening and closing torque is large, the structure length is longer, usually the nominal diameter of DN are limited to the following 200mm. The flow resistance of the stop valve is greater. Thus limiting the wider use of cut-off valves.
- Q:Are the gate valves and check valves of the same type?
- Not the same gate valve, it is a kind of opening and closing function (i.e. switch) of the valve, it is on the gate lifting and play the role of the switch, the switch is to be applied by external force (hand wheel, electric, pneumatic and hydraulic) it is not required to;
- Q:What does the check valve "H44Y-160" mean?
- H- check valve, 4 flange connection, 4 spiral structure, Y- sealing surface material is hard alloy. 160 table nominal pressure 16MPa
- Q:What is the HH44X-16 H of the double acting slow closing check valve? Can you explain it in detail?
- 1. The first H is the meaning of the check valve (the first letter of the Chinese phonetic alphabet). The second H is the meaning of "slow closing" (the first letter of the Chinese phonetic alphabet).
- Q:Does the regulator have a check action? If yes, can I use it as a check valve?
- No, it can only be used for regulating pressure. It can not replace the check valve.
- Q:What does the H/F/P stand for in the check valve H41H/H41F/H41P?
- The first H represents the check valve, the 4 represents the flange, and the 1 represents the lift type, and the second H represents the seat seal surface. The material is alloy steel or stainless steel. The P H41P said seating for boron steel
