Use and application of ball check valve

Valve manufacturers usually use rubber-covered ball as the valve disc. The principle is that under the effect of the medium, it can roll back and forth on the slideway in the valve body, and then open or close the valve. The main features of HQ44X single-ball micro-resistance spherical check valve and HQ45X double-ball micro-resistance spherical check valve are large flow rate, small flow resistance pressure loss, good sealing performance, silencing and sealing, which can reduce water hammer waves. Horizontal or straight equipment is acceptable. The micro-resistance spherical check valve can be used at the outlet of the water pump of the cold water, hot water, industrial and daily sewage pipe network to prevent the medium from flowing back. In order to avoid the back flow of the medium, check valves should be installed on the equipment, equipment and pipelines.


Spherical check valves all use rubber covered balls as their discs. Their principle is that under the action of the medium, they can roll back and forth on the slideway in the valve body to open or close the valve. The main features of HQ44X single-ball micro-resistance spherical check valve and HQ45X double-ball micro-resistance spherical check valve are large flow rate, small flow resistance pressure loss, good sealing performance, silencing shut-off, which can reduce water hammer wave, horizontal or vertical installation It's all possible. The micro-resistance spherical check valve can be used at the pump outlets of cold water, hot water, industrial and domestic sewage pipe networks to prevent the medium from flowing back. In order to prevent the medium from flowing back, check valves should be installed on equipment, devices and pipelines.

First of all, the ball check valve has a very good energy-saving effect. Generally, the energy-saving water-proof hammer and wear-free ball check valve saves about 32000-55000 degrees annually, which is more than the usual micro-resistance slow-close check valve and swing check valve section The electric effect is obviously better; secondly, its waterproof hammer effect is also very prominent. It has been proved by certain comparative tests that the water shock wave intensity of the energy-saving waterproof hammer non-wear ball check valve is about twice that of the swing check valve , Completely avoid the occurrence of destructive water hammer; besides, its service life is very considerable, even up to ten years without maintenance. The ball check valve has no so-called joint parts, and there is no relative mechanical conflict. Movement, so it has no vulnerable parts, which naturally increases its service life. It has good sealing performance and can be widely used in various media such as clean water, clean water, turbid water, etc.; modified rubber raw materials can also be used in other liquid media. Not only that, but it is also easy to maintain. If the check valve needs to clean foreign objects or replace the rubber ball, the rubber ball can be taken out from the maintenance port or inserted.
