- Q: What are the differences between different check valves applications? For example, is the fire pump outlet swing check valve or a silent check valve? According to 35How to recognize single wall corrugated pipe and double wall corrugated pipe? Which is better?.What's the use of the silent check valve? And the bellow problem below, is there no answer?
- General pump station project, for the pump outlet check valve, the following principles should be observed;The outlet check valve shall be used when the diameter of the outlet pipe of the pump is smaller, that is, DN<50mm.The pipeline of the pump outlet pipe diameter DN is larger than 50mm, should be used in swing check valveSwing check valves can be installed horizontally or vertically.
- Q: Why is the check valve necessary? Why should it be checked back?
- 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.Check valve installed in the pipeline system, the main role is to prevent media backflow, check valve is a kind of pressure on the media to open and close the automatic valve. The clip type check valve applies to nominal pressure PN1.0MPa~42.0MPa and Class150~25000; nominal diameter DN15~1200mm and NPS1/2~48; work temperature -196~540 degrees of various pipelines, used to prevent medium flow back. By choosing different materials, it can be applied to many mediums such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and uric acid.
- Q: Why should the check pipe be added to the chilled water pipe of the air conditioning unit?
- The air conditioning unit you refer to the indoor air terminal or refrigeration unit (the air conditioning form of this with you to say you take the form of water source heat pump and board for the air conditioning unit, you said that is placed in the interior of the water ring pump unit). The air conditioning unit when you refer to the refrigeration unit, for example by pressing in the form, you will need to pump and the unit set between the check valve to prevent the pump start and stop when the air conditioning water poured into the pump, the damage of equipment; air conditioning units when you refer to (e.g. water loop heat pump indoor unit) in the room, there is no need to set the check valve, usually in the import chilled water is arranged on the electric valve two, flow switch, exhaust valve and so on can.
- Q: Which type of check valve should be selected for vertical pipes?
- The check valve on the vertical pipeline shall ensure that the spool goes back to its position when the fluid is stationary and reversed.Optional:Butterfly check valves, pipes of low pressureVertical lift check valve, high pressure resistance, good tightnessSwing check valve: flow must be from the next up, the pipe diameter is unlimited
- Q: What is the function of the check valve installed in the water meter before entering the residential water?
- The check valve installed before the water meter is convenient for the maintenance, maintenance and management of the user's water.
- Q: Tap water tank with vertical and horizontal check valve.
- Look at your pipe installation position, if it is vertical, of course, the vertical check valve is good, if it is horizontal, of course, choose a horizontal check valve.The function of the check valve is to ensure the flow of the fluid in one direction. The moving parts are usually pressed against the seat to form a seal. Small pressure must be applied to moving parts to open the valve. Once opened, fluid power is generated to allow the valve to open or increase opening. Before the valve closes, fluid flow must stop. Fluid power generated by fluid flow prevents all valves from closing. The spring can be used or not to control the opening and to close it. Some check valves rely solely on gravity to provide closing force. Valves that rely on gravity must be installed according to the manufacturer's instructions. If horizontal pipes are laid, the slope of a short distance local pipe must be changed.The swing check valve is powered by gravity. When the valve is opened, the force required to control the valve opening is increased. If the balance between disc weight and fluid dynamic force is incorrect, the valve will not be fully opened. Increasing flow speed may cause unexpected corrosion or erosion damage, so gravity driven valves must be used to meet operating conditions.When the valve is fully opened, the disc or piston stroke must be limited by the stopper. Fully open valve, but not limited, the valve is easy to vibration. Vibration may cause hinge pins or pistons to wear rapidly. Valves using springs may suffer from early spring faults (caused by fatigue). Vibration may be caused by vortices or disturbances. When the fluid has some viscosity, the fluid damping can control the vibration. Valves with springs may be fitted with different rigid springs. If the full stroke stops, including extrusion, to prevent backlash after rapid opening, this can be an effective vibration damper.
- Q: Ask questions about the installation of check valves after water meters
- Generally installed after the water meter. The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter. A check valve is installed after the water meter, so that the situation can be avoided.
- Q: Fire hood fire check valve okay?
- 1, the new product role2, the role of soot exhauster smoke exhaust fumes sent to the public flue gas pipeline, with the smoke fumes from the flue gas flow into the room to ensure that the quality of the domestic air environment, home health3, fire valve temperature control device and block check plate up to prevent the flame through public exhaust pipe series.4, the specific selection to check, see products through fire products, testing, assessment, no certificate, and price
- Q: I have to use a check valve to prevent return water due to pipe installation problems due to regular water supply. But the recent discovery of a running water phenomenon, just on a full tank of water slowly from the pipeline flow away, but not all go, a flow did not flow, time is not the same, but sometimes sometimes does not flow, this is going on, ask professional personage answer
- The problem can't be solved: if you change the pipe, you'll have a vertical check valve
- Q: Does the Vatti range hood e601a2z have check valves?
- As long as the regular manufacturers of smoke machines must be equipped with check valves, Vatti as a well-known brand of kitchen electricity, this should not worry about you
