High-speed one-way valve assembly for water-jet loom

Abstract

The invention discloses a high-speed one-way valve assembly for a water-jet loom. The high-speed one-way valve assembly comprises a valve seat and a valve cover which is arranged above the valve seatand provided with a water inlet, and the high-speed one-way valve assembly is is characterized in that a sealing sheet is arranged in the valve cover; a cavity is formed in the valve seat, and a valveelement is movably installed in an inner cavity of the valve seat and can move up and down along the inner cavity wall of the valve seat; the top of the valve element serves as a curved surface, a reset spring is arranged at the bottom of the valve element, one end of the reset spring is installed on the valve seat, and the other end of the reset spring abuts against the valve element against thewater inlet in the valve element; and an outlet hole is formed in the bottom of the valve seat. The valve cover, the sealing sheet and the valve element are of a streamline structure on the fluid section, so that flowing resistance is reduced, the turbulence condition of fluid in the one-way valve assembly is reduced, the stability of the fluid passing through the one-way valve assembly is improved, and pressure losses are reduced. The response speed and the sealing effect of the one-way valve assembly are improved.

Description

technical field [0001] The invention relates to a high-speed one-way valve assembly for a water jet loom. Background technique [0002] The check valve assembly is a commonly used component in the fluid system. Common check valves are composed of valve body, valve core, spring and other parts. In normal use, the liquid flows through the one-way valve, relying on the pressure of the fluid in the pipeline to push up the disc controlled by the spring to achieve the purpose of liquid circulation; Reset the disc, and the one-way valve is closed to prevent the liquid from flowing backwards. This one-way valve only allows flow in one direction, and realizes the one-way cut-off function by means of the pressure difference at both ends. The existing one-way valve for water jet loom is a high-frequency action component, which can open and close as high as 700~1200 times per minute, and must ensure the stability of fluid pressure and flow rate. Since the loom is generally running co...

AI Technical Summary

Problems solved by technology

Since the loom is generally running continuously for 24 hours, it will not stop if there is no fault. The spring force will decrease during long-term use, and the valve core will be slow to reset, and the high-frequency movement of the valve core will easily cause damage and rupture, making the work ineffective. , affecting the continuous operation of the water jet loom
