- Q: My house is public flue, a total of six floor I live five floors, with the side suction hood, hood in the windy outside started as soon as the check valve pops ring from occupancy, have what way?
- The hood check valve is in two halves of plastic. It is too light and the wind vibrates. You can add some things, as long as the soot blowing function is OK (try several times). Able to solve problems.
- 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: The difference between backflow preventer and check valve
- In abnormal pressure (i.e., the outlet pressure is higher than that of the middle cavity), even if the two check valve can not reverse sealing, safety relief valve can automatically open the reverse water emptying, and the formation of air separation, ensure the health and safety of water upstream.
- Q: Pump adapter need check valve?
- Pump adapter need check valve?
- Q: How can the check valve be distinguished from the cut-off valve?
- Turn on and off. Is the cut-off valve, can not turn off, open, automatic, in the middle of a plate will move, that is, check valve
- Q: Tap water tank with vertical and horizontal check valve.
- Ball valves usually have very narrow seats, and may remove solids and make seating more efficient.The problem of vibration may be limited to small valves. When the valve is large, the inertia of the moving parts increases. The increased inertia may effectively damp the vibration and cause delayed closing, after the backflow has started. The damping of the seat becomes very important.All valves must check the flow path area and calculate the flow velocity for the design operating conditions. The area of the disc and piston is as important as the area of the main orifice. The smaller runner areas are corrosion prone and may cause cavitation wear.For specific functions, the valve body of the check may include auxiliary connections such as vents and drains. Hot applied valves may sometimes have a bypass valve to allow the system to warm up at low flow.

- H- check valve code4- flange connection4- rotary single structureH sealing material is Cr13 stainless steel25-25 kg pressure 2.5MPaP- stainless steel 304
- Q: We are high-rise buildings, with the smart recharge meters, before always someone to reflect the water used soon, 27 tons of water in only a month has gone. Later I heard that the water meter in front of a check valve on it, but when the five tons of water after the use of nothing, and nothing. Why does that happen? Does the check valve stop the water meter from idling?There is a special case, thirty storey building, booster pump has a pressure in the debugging of the fifteenth layer of what, every time on the twentieth floor of the owners reflect his home water intermittent, sometimes when a shower suddenly no water, we always to reflect the property many times, we are the plumber debugging a few times, or not. Later said that can not be adjusted, and then the tune will burst, and this is how it happened? How can I solve this problem? Why didn't the owners of the thirty and fifteen floors reflect the shortage of water pressure? But the owners of the more than 20 floors are so unlucky?
- 2.3 installation methods and installation quality2.3.1 since the water meter is now out of the door, most of the units are all concentrated in one box and installed on the first floor. Taking into account the freezing cold winter and the meter, with 6 or 12 meter with a diameter of 40mm- 50mm diameter pipe, tables and small spacing and straight sections set aside less water, this will also affect the normal water metering, causing water rotation.2.3.2 installation quality, pipeline projects are basically buried in the ground or in the wall, is a hidden project. National construction standard pipe provides various pipe pipeline construction installation requirements, construction process, acceptance criteria and matters needing attention, but in the construction site, some managers do not according to the requirements of the code construction, more or less there are some quality problems caused by pipeline.
- Q: Is the tank stop valve a non-return valve or a check valve?
- The valve has a knob, and the controller can control the forward flow. Because of its special structure, the fluid can not flow backwards even if there is no artificial valve.
- Q: How to install the kitchen flue check valve?
- 1, vertical transport, the flue should take protective measures, and must be two lifting.2. Locate the center line of the flue position. In the reserved hole, draw down four vertical central lines from the roof, and draw 2 orthogonal central lines on the floor plane.3, the flue to the scene, the first flue hanging to the roof, surrounded by the center line of pop in the flue, and the flue of the reserved hole slowly down the electric hoist, from top to bottom layer installed flue in place, the center line correction. The center line of the flue and the center line of the reserved hole should be less than 1cm, the deviation of the centerline of the upper and lower flue is not greater than 1cm, and each flue must be guaranteed vertically and vertically.4, the installation of flue should each layer as bearing, bearing steel 2 root diameter over 14mm?.5. After the flue is installed, install the check valve hole at each flueFire type flue check valveFirst, stir the cement with a special glue, coat the edges of the check valve, and then install it at the opening of the check valve.6, the construction should be reserved at all levels of the hole, covered with a cover plate, to ensure safety in construction, to prevent construction waste fall into the flue.7, the flue is thin-walled components, in handling and installation should be gently handle, not to impact, not in the pipeline to pile other heavy objects and walking.8, the roof flue should be in the roof insulation layer, fire layer before construction. 9, the use of gas water heater exhaust system is strictly prohibited.
