Abstract

The invention discloses a kind of assembled vapour accessory structure and process thereof, feature is that gasket body top and bottom have stigma, stigma top has hat head, has gap, gasket body two-port to have first step, second step between hat head to gasket body.Gasket body be 1/4 fritter totally 4 pieces be assembled into ring washer, during installation, the second step card of one piece of scatter cushion sheet port is pressed in the first step of another scatter cushion sheet port, the rest may be inferred by analogy constitute circular washer.Advantage is: technique is simple, and sealing ring layer by layer is arranged, and effectively prevents machine parts from leaking or oil leakage phenomenon.

Description

A kind of assembled vapour accessory structure and process thereof

Technical field

The invention belongs to engine art, especially relate to a kind of assembled vapour accessory structure and process thereof.

Background technology

Traditional gasket seal is many with metal or nonmetal tabular material, the technique such as cleaved, punching press or cutting make and Becoming, for being tightly connected between the parts and parts of machinery equipment, water hole or oil-through hole to machine seal.Mesh Front gasket construction is varied, and common gasket seal is at non-metallic gasket sealing gasket gluing or in metallic gasket punching press Form convex tendon, thus reach better seal effect, but non-metallic gasket is in use, pad is coated with silica gel easy Falling off, manufacturability is bad, easily occurs leaking or oil leakage phenomenon.

Summary of the invention

The present invention is directed to the above-mentioned deficiency of prior art, it is provided that a kind of good airproof performance, install easily, simple in construction, processing Convenient, can effectively prevent machine from leaking or a kind of assembled vapour accessory structure of leakage of oil and process thereof.

The technical solution of the present invention is such that a kind of assembled vapour accessory structure, including gasket body, cross nail, Interstitial hole, hat head, first step, second step, stigma, gap, interface, it is characterised in that gasket body (1) top and bottom have Stigma (7), stigma (7) has hat head (4) on top, has gap (8), gasket body between hat head (4) to gasket body (1) (1) two-port has first step (5), second step (6).

Gasket body (1) be 1/4 fritter totally 4 pieces be assembled into ring washer, during installation the second of one piece of scatter cushion sheet port Step (6) card is pressed in the first step (5) of another scatter cushion sheet port, and the rest may be inferred by analogy constitutes circular washer.

The present invention compared with prior art provides the benefit that: by extruding one-shot forming, due to spiral shell shape head convex tendon and pad Sheet main body consubstantiality is connected, and structure is more stable, gasket seal can design multiple tracks convex tendon as required and form multiple-sealed ring, Sealing effectiveness is more preferably.Further, the cross section of convex tendon is flat arc, good buffer effect after stress, is prevented effectively from stress and concentrates and cause Gasket seal cracking phenomena, be greatly prolonged the service life of gasket seal.

Accompanying drawing explanation

Fig. 1 is the assembling schematic diagram of the present invention；

Fig. 2 is that the present invention is by the section enlarged diagram in A-A direction in Fig. 1.

Reference: gasket body (1), cross nail (2), interstitial hole (3), hat head (4), first step (5), second Rank (6), stigma (7), gap (8), interface (9).

Detailed description of the invention

The invention will be further described below in conjunction with the accompanying drawings.

Embodiment 1, referring to the drawings, a kind of assembled vapour accessory structure and process thereof, including gasket body (1), cross nail Hole (2), interstitial hole (3), hat head (4), first step (5), second step (6), stigma (7), gap (8), interface (9).Pad Sheet main body (1) is the auto parts machineries such as head gasket, pump pad, axle pad.Gasket body (1) manufactured out nail depending on each different accessories (2), interstitial hole (3).Axial line is divided into four pieces to be assembled into circle gasket body (1) by the design of Fig. 1 view by gasket body (1) Pad, each scatter cushion sheet port is handing-over mouth, and each fritter washer ends is up/down steps formula, and it pads to intersect with adjacent assembly and is One second step (6) on next, first step (5), in adjacent two pieces of pads, second step (6) is superimposed with another block gasket-end The first step (5) of mouth.Gasket body (1) top and bottom have hat head (4), hat head (4) to have stigma between gasket body (1) (7), hat head (4) has gap (8) for compressed air aerofluxus release between the plane of gasket body (1) upper and lower end face.

Embodiment 2, a kind of assembled vapour accessory structure, including gasket body, cross nail, interstitial hole, hat head, First Rank, second step, stigma, gap, interface, it is characterised in that gasket body (1) top and bottom have stigma (7), stigma (7) to have on top Hat head (4), have between hat head (4) to gasket body (1) gap (8), gasket body (1) two-port have first step (5), Second step (6).Gasket body (1) be 1/4 fritter totally 4 pieces be assembled into ring washer, one piece of scatter cushion sheet port during installation Second step (6) card is pressed in the first step (5) of another scatter cushion sheet port, and the rest may be inferred by analogy constitutes circular washer.

Embodiment 3, gasket body outer circumference crosses nail for uniform four, medial center position according to parts oil-through hole or The size of water hole offers interstitial hole, is provided with two circle convex tendons between mistake nail and the interstitial hole in gasket body, and two circles are convex Muscle lays respectively on the circumference of the different radii with gasket body center as the center of circle, and, each circle is included in gasket body altogether Lateral symmetry arrange a pair convex tendon.In actual application, can select to add in gasket body according to the size of parts flange Work 1～3 encloses convex tendon.Preferably convex tendon width B is 2～10 with height H ratio, the width B span of this convex tendon be 0.1mm～ 0.5mm, highly H are 0.2mm～5mm, and preferably convex tendon width B is 3 with the ratio of height H, makes this gasket seal stress more Uniformly, sealing effectiveness is more preferably.Use AEM elastomeric material；Convex tendon, by extruded, is connected with gasket body consubstantiality.Installing When using this gasket seal, convex tendon is avoided to come off completely and leakage of oil or drainage.Not only solve pad manufacturability issues, also Effectively raise sealing property.

Claims

1. an assembled vapour accessory structure, including gasket body, cross nail, interstitial hole, hat head, first step, second step, Stigma, gap, interface, it is characterised in that gasket body (1) top and bottom have stigma (7), stigma (7) to have hat head (4), cap on top Shape head (4) has gap (8), gasket body (1) two-port to have first step (5), second step (6) between gasket body (1).

2. the process of an assembled vapour accessory structure, it is characterised in that gasket body (1) be 1/4 fritter totally 4 pieces be assembled into Ring washer, during installation, second step (6) card of one piece of scatter cushion sheet port is pressed in the first step of another scatter cushion sheet port (5), the rest may be inferred by analogy constitutes circular washer.
