Q:Butterfly check valve should be equipped with special flange for butterfly valve
No, with a special appearance Jansen point flange butterfly valve. It can barely be installed without special flanges
Q:What is the difference in price between the check valve HH48X-10C and the HH49X-10C?
Since this model has exceeded the standard requirements, so there is no uniform manufacturers. There are dozen HH49X, there are also playing HH48X, HH49X, in fact, are the same kind of valve.
Q:How can the check valve at the flue port of the range hood be changed or cleaned?
If the flue hanging in the shed, it should be at the check out. Check valve with a machine.So I would not advocate the construction of flue hanging in the shed, net height kitchen, gas capacity is small this is big, the flue pipe exposed, there are many ways to deal with it.If the valve stuck inside, also find what professional people, find out what carpenter, solved the problem.
Q:Install check valve is not afraid of water, in case the back of the water pollution?
The function of the check valve is to prevent water from flowing back. It is mainly used at the pump outlet to protect the water pump. Of course, it is also possible to prevent backwater pollution. Where to use it, mainly to function, is not necessarily to be applied in a traditional way!
Q:Swing check valve can prevent any sewer defection
Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents. This kind of valve should be installed horizontally in the pipeline.
Q:What's the difference between check valves and non-return valves?
Other check valves (check valves), such as blowdown check valves,Civil air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.
Q:Back pressure valve and check valve difference
Oil is generally put into the wells of the check valve calling back pressure valveCheck valve is a general name, mainly lifting type and swing type.
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:Why is the water ring vacuum pump equipped with check valves?
The check valve is a one-way valve, the instantaneous vacuum of the stopping pump is higher than the pump cavity, and the gas enters the pump cavity from the exhaust port, and the water pressure is connected to the vacuum pipeline, and the function of the check valve is to prevent water from entering the pipeline
Q:What's the size of the check sleeve?
According to the valve connection mode (thread connection, flange connection), select valve rating, modify the valve name
We mainly produce various check valves (for example,single disc swing check valve,double disc swing check valve,ball check valve,lift check valve, butterfly valves,diaphragm valves ,ball valves and so on). Our products are widely used in municipal water and wastewater ,oil,chemical, food and other fields.Our entire valves are designed and manufactured according to ANSI (ASME), DIN, BS, JIS and other standard. Also, we ensure the best quality for customers, and our strict quality assurances systems are conducted throughout the entire production at the standard of ISO9001:2008 and CE.
