- Q:Are rubber check valves and swing check valves the same type of valves?
- Swing check valve is a check valve, the structure of the valve for the rotation of the axis of the general term, rubber valve check valve is people's usual name for H44X, only a swing check valve
- Q:To prevent water meter rotation, where should the check valve be installed?
- Place it at the top of the water meter, as you can see, near the valve
- Q:Why is the intelligent water meter equipped with a check valve, still can not prevent the water meter idling?
- 4. conclusionMany reasons for water rotation, but on the whole can be divided into two: one is the subjective factors, namely subjective causes, such as construction acceptance, human responsibility caused by Water Leakage, original gas gathering, which can strengthen the construction management, improve the staff's work and to improve the level of responsibility. The two is the objective factors, the main characteristics of the water itself, by the characteristics of pipeline and the level of technology development in the external objective factors, on the one hand to work in the future continue to explore the improvement will be improved.
- Q:What's the use of the check valve?
- 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:What kind of check valve is used to prevent the return water?
- You should be horizontal check valve, with pressure difference, water pressure is not lost; or a check valve inside where the card, must be a certain pressure to baffle back.
- Q:What is the difference between the silent check valve and the silent check valve?
- It can be installed horizontally or vertically. The valve is loaded by spring, and its quick closing can effectively eliminate the water hammer. It has good sealing performance and no noise.
- Q:Why should the check pipe be added to the chilled water pipe of the air conditioning unit?
- Check valves are usually installed at the exit of a group of pumps. I have not heard of the installation of check valves at the location of the air conditioning unit.The function of the check valve is to prevent backflow. Prevent backflow of water in water pipe and knock out impeller of water pump.
- Q:What's the difference between the cut-off check valve and the stop valve?
- The principle difference between the check valve and the cut-off valve is that the non-return valve allows only one-way flow of liquid, allowing only one flow from one end to the other. It is a one-way valve, and the shut-off valve allows two-way flow. The biggest difference is the structure of the valve head and valve closing method is connected by the check valve is separated, the appearance of the cut-off valve import and export in a plane and the cut-off valve is a one-way valve, arrow shell stop check valve on the other.
- Q:What is the function of the ventilator's check valve?
- When the soot exhauster stops working, the one-way valve plate is automatically closed under the action of gravity, and the fume passage is isolated from the common flueThe smoke in the flue doesn't flow back in.
- Q:How to control the common flue return and smoke return?
- In the hood outlet to install a reasonable design, shut tight, open the hood in place, can be easily wind blown open, will not be open to the flue suction, and the blade contact area is very small, and a sealing ring, not to hinder the blade opening exhaust flue check valve closed Miller beauty you can eliminate the smoke intrusion and poor smoke.
