AI Technical Summary
Traditional one-way valve discs lack ductility and resilience in their connecting strips, resulting in insufficient sealing performance, connection strength, and structural stability, especially poor reliability under high pressure.
A one-way valve plate for a pump was designed, which adopts an annular body, a sealing part and a connecting part. The connecting part consists of a first flared section, a connecting section and a second flared section. The connecting section is wavy and made of stainless steel. A bending section is set on the outer side of the first flared section to increase the structural strength.
The design of the corrugated connecting section and the bending section increases the movable distance and structural strength of the sealing part, improves the sealing performance and connection strength, and enhances the reliability under high pressure environment.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to one -way valve piece field especially relates to a pump is with one -way valve piece. BACKGROUND
[0002] One -way valve piece is the component that fluid delivery equipment is commonly used, is widely used in pump, pneumatic device etc., traditional one -way valve piece includes annular body, sets up in annular seal piece and is used for connecting seal piece and annular body's connecting strip, traditional connecting strip is long strip, long strip's connecting strip telescopic length is limited and lacks resilience effect, thereby make traditional one -way valve piece in sealing performance, connecting strength and structural stability often exist shortage, reduced its reliability under high pressure environment, a kind of one -way valve piece that can provide good sealing, with high -strength connection is particularly important. SUMMARY
[0003] The utility model provides a pump is with one -way valve piece to the connecting strip of traditional seal piece of prior art lacks the shortcoming of limited extensibility telescopic ability, and one -way valve piece is provided.
[0004] In order to solve the above technical problem, the utility model discloses the following technical scheme: a pump is with one -way valve piece, including annular body, the annular body is equipped with seal part and connecting part, connecting part is used for connecting annular body and seal part, the connecting part includes with first flared section, connecting section and second flared section, first flared section is connected with annular body and is set, second flared section is connected with seal part and is set, the connecting section is set in wave curve shape.
[0005] The utility model further sets up: the connecting part is provided with two, and two the connecting part is symmetrically set.
[0006] The utility model further sets up: the annular body, connecting part and seal part are integrally formed.
[0007] The utility model further sets up: two the first flared section of connecting part is integrally set.
[0008] The utility model further sets up: the annular body, connecting part and seal part all adopt stainless steel material quality.
[0009] The utility model further sets up: the side of first flared section is set with the bending section of bending.
[0010] The utility model further sets up: the bending section is set with first flared section and is ninety degrees.
[0011] The utility model further sets up: the seal part is round.
[0012] The utility model discloses a remarkable technical effect has through the movable distance of the connecting part driving the sealing part that the wave -shaped connecting section has increased, the structure strength between the first flared section and annular body that the bending section has increased, and the rebound effect of the sealing part is increased simultaneously with the wave -shaped connecting section. BRIEF DESCRIPTION OF DRAWINGS
[0013] Figure 1 It is the structural diagram of one-way valve piece for pump in example one.
[0014] The part names referred to by the numbers in the above drawings are as follows: 1, annular body; 2, sealing part; 3, connecting part; 31, first flared section; 32, connecting section; 33, second flared section; 34, bending section; 4, mounting ear; 5, mounting hole. DETAILED DESCRIPTION
[0015] The utility model will be further described in detail in combination with the drawings and examples.
[0016] Example one:
[0017] A kind of one-way valve piece for pump, in combination Figure 1 , including annular body, sealing part and connecting part, annular body is circular, and symmetrically set up mounting ear with protruding, mounting hole is set up on mounting ear, sealing part is circular, the center of circle of sealing part and the center of circle of annular body are coincidently arranged, connecting part sequentially includes first flared section, connecting section and second flared section, first flared section is connected with the inner circle of annular body, second flared section is connected with sealing part, connecting part, sealing part and annular body are integrally formed, one-way valve piece is stamped from 0.3-1mm thickness stainless steel sheet body.
[0018] Connecting section is wave-shaped, two connecting parts are symmetrically arranged in the embodiment, and the first flared section of the two connecting parts is integrally arranged, and the two wave-shaped connecting sections are also symmetrically arranged, the first flared section is gradually expanded towards the width of the first flared section and the annular body connection end, and the second flared section is gradually expanded towards the width of the second flared section and the sealing part connection end.
[0019] Sealing section and annular body are concentric and spaced apart, connecting section and annular body inner circle and sealing part are spaced apart, since one-way valve piece is stamped from stainless steel sheet, bending section is provided on the outer side of first flared section by secondary stamping and bending, and bending section is bent by ninety degrees with first flared section, since the middle part of the first flared section of the two connecting parts is integrally arranged, and the bending section is located outside the first flared section of the two connecting parts.
