One-way valve for high-pressure fluid

Abstract

The invention provides a one-way valve for high-pressure fluid. The one-way valve comprises a valve body, connecting mechanisms, a tapered ejector rod, a spring I, baffles and torsion springs. The twoconnecting mechanisms are located at the two ends of the valve body correspondingly, the connecting mechanisms comprise sliding blocks, springs II, connecting rods and spherical communicating parts,the four sliding blocks are installed on the valve body, the springs II are arranged between the sliding blocks and the valve body, the connecting rods are arranged on the sliding blocks, the spherical communicating parts are arranged on the valve body, the taper ejector rod is movably installed in the valve body, the two baffles are hinged to the interior of the valve body, and the baffles are provided with the torsion springs. Dual fluid return stop is achieved through the tapered ejector rod and the two baffles, the situation that the valve body is invalid since one component cannot normally work due to the fact that sticky fluid is introduced into the valve body for a long time is avoided, the one-way valve makes contact with a connecting pipeline through the spherical communicating part and fixed to the pipeline through the connecting rods, and therefore the valve can be connected with pipelines with different sizes since the connecting rods can move in the axial direction and radial direction of the valve body.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a one-way valve for high-pressure fluid. Background technique [0002] The publication number is CN203963143U, which discloses a conical check valve, which shields the passage of the valve body through the retaining ring at the end of the valve stem, and when feeding, the fluid will lift the retaining ring and push the spring to be in a compressed state so that the fluid During the return flow, the spring pushes the retaining ring to block the flow channel to achieve the effect of one-way flow, but this one-way valve only uses the retaining ring to realize one-way return. When the valve body is used for a long time in the state of viscous fluid, it is easy to cause the spring to be difficult. pop-up, which is prone to poor occlusion effects.
