Embodiment Construction
[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] Such as Figure 1~Figure 3 As shown, the present invention includes a valve seat 2, a valve core 6, a front pipeline 3, a rear pipeline 1 and a stainless steel stopper 7 that limits the rotation of the valve core 6, the front pipeline 3, the valve seat 2, and the rear pipeline 1 are connected in sequence, and the valve seat 2. There is a valve chamber, the diameter of which is larger than that of the front pipeline 3 and the rear pipeline 1. The valve core 6 includes a conical valve core 6. The outer peripheral surface of the conical valve core 6 protrudes radially to form a plurality of The distributed bracket 8, the conical valve core 6 is movably installed in the valve cavity through the support of the bracket 8, the front end of the valve core 6 is provided with a chamfered surface, and the valve seat 2 includes a tubular seat body ...

The invention discloses a silencing one-way valve and a manufacturing method of a one-way valve limiting member and belongs to the field of one-way valves. A front pipeline, a valve seat and a rear pipeline are communicated sequentially, the valve seat is provided with a valve cavity, diameter of the valve seat is greater than the front pipeline and the rear pipeline, a valve element comprises a conical valve element body, the outer peripheral face of the valve element body radially protrudes outward to form multiple supports uniformly distributed circumferentially, the valve element body is mounted in the valve cavity through the supports, the valve seat comprises a tubular seat body and front and rear end caps mounted at two ends of the seat body in a covering manner, each of the front end cap and the rear end cap is provided with a through hole, connecting pipes axially extending towards two ends are arranged on opposite outer side end faces of the front end cap and the rear end cap respectively, and the front pipeline and the rear pipeline are fixedly inserted into the connecting pipes respectively; the silencing one-way valve further comprises a limiting member limiting rotation of the valve element, the limiting member comprises an axial limiting portion and an annular fixing portion which are connected into a whole, and one end of the axial limiting portion is connected together with an inner ring of the annular fixing portion while the other end of the same extends in the axial direction of the inner cavity of the seat body in a suspended manner.
Description
technical field [0001] The invention belongs to the field of one-way valves, and in particular relates to a method for manufacturing a sound-absorbing one-way valve and a one-way valve limiter. Background technique [0002] The one-way valve is a device in which the fluid can only flow along the water inlet, but the outlet medium cannot flow back. The fluid flows from one end to the other. When it flows through the valve seat, it pushes the valve core. The tapered part of the valve core is in contact with the valve seat. It is completely closed, and there is a channel between the valve body and the valve seat of the spool for fluid to pass through. After the fluid passes, the spool returns to its original position under the pressure of the elastic member or the fluid to block the passage again. For the one-way valve with this structure, in order to fix the inner valve seat, a groove is usually pressed on the outer casing to limit the fixed valve seat, but there will be a gap...
