Background
The check valve assembly is a commonly used assembly in a fluid system, and the commonly used check valve is composed of a valve body, a valve core, a spring and other parts. When the valve is normally used, liquid flows through the one-way valve, and the valve clack controlled by the spring is jacked up by the pressure of the fluid in the pipeline, so that the aim of liquid circulation is fulfilled; when the pressure of the pipeline liquid at the inlet section of the one-way valve is smaller than that at the outlet, and the fluid flows reversely, the spring resets the valve clack, and the one-way valve is closed to prevent the liquid from flowing backwards. The one-way valve only allows one-way flow, and realizes a one-way stopping function by virtue of the pressure difference between two ends. The existing check valve for the water jet loom is a high-frequency action assembly, the opening and closing times per minute are as high as 700-1200 times, and the stability of fluid pressure and flow rate is ensured. Because the loom generally runs continuously for 24 hours, if the loom is not stopped without failure, the spring elasticity is reduced, the valve core is slow to reset, and the high-frequency movement of the valve core is easy to damage and break, so that the operation is invalid, and the continuous running of the water-jet loom is influenced. The main performance requirements of the non-return valve are: the pressure loss is small when the liquid passes through, the reverse cut-off response is rapid, and the reverse sealing performance is good.
Therefore, the utility model discloses design a high-speed check valve subassembly for hydraulic loom according to these technical requirements in order to improve fluidic stability, reduce pressure loss, improve the response speed of non-return action, cut-off leakproofness, check valve's life.
