- Q: What is the difference between check and check valves? Check and check valves?
- 3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar
- Q: What does the check valve "h61h-25 H" mean?
- From the model analysis, for the cast steel welding lift check valve, it depends on your valve is not it
- Q: In the water supply system, water pump and water pump without check valve, a water output to another without pump water pump, effect of rotation, it will cause what kind of damage to the pump?
- The main function of the check valve is to prevent water hammer, and the impact of water hammer on the drainage system is fatal.
- 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: There is a check valve at the inlet of Haier electric water heater to prevent water from flowing back. Because there are many hot water used in the house, should the hot water be fitted with check valve?Can the hot water outlet be fitted with check valves? The hot water pipe is too long for hot water to flow back into the heater... Is it possible to install two check valves to affect the normal use of the heater?
- Hot water outlet should be equipped with check valve, for the following reasons:Closed type electric water heater in the outlet by one or more water control valves and water storage type electric water heater, and work in tap water under pressure. The utility model has the advantages of flexible installation position, high water outlet pressure, small heat loss, etc.. But because its inner liner is working under pressure, it needs thicker material and high manufacturing process. The outlet of open type electric water heater is opened and water is controlled by a valve on the water inlet pipe.
- Q: What is the reason that the valve is not used for a period of time?Anonymous browsing | 314 times
- 4 the vertical lift check valve shall be mounted on a vertical pipe.5, the lift type horizontal check valve shall be installed on the horizontal pipe.6. Do not check the weight of the valve in the line. The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system.
- Q: Which side of the gate is the fire check valve in the pump room?
- The check valve is installed between the shock absorbing flexible joint and the water outlet control valve at one side of the water outlet pipe of the water pump
- 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 it better to have explicit rules in the relevant specifications? Thank you, ah, ah, urgent.
- 8.5.5 vertical exhaust lines for kitchens, bathrooms, toilets, etc., should be taken to prevent backflow or to set fire dampers on the branch pipe.In addition, there are similar provisions in the code for fire protection in architectural design, which are not stated.
