Abstract

A gasket includes a first face separated a predetermined distance from a second face, having a common though-hole. A metal frame is disposed between the first and the second faces, the metal frame supporting a first feature extending outwardly from opposing planar sides of the frame towards the first and the second faces, as well as supporting a second feature also extending outwardly from opposing planar sides of the frame towards the first and the second faces. The first feature is compressible when pressure is applied to the first and the second faces, and the second feature is incompressible when the pressure is applied to the first and the second faces. The first and the second features are continuous and concentrically aligned with one another about the through-hole, and the first feature is inclined towards the through-hole.

Abstract

A ropy packaging apparatus integrating measuring, cutting and protecting functions, comprising a box body (1), a measuring scale (5) and a cutting mechanism (4, 24). An upper cover of the box body of the apparatus and a side plate connected to the upper cover can be overturned and opened from side faces, and the cutting mechanism (4, 24) is disposed on the sidewall in the box body (1); the cutting mechanism (4, 24) comprises a head and a base, the head being fixed to the base, wherein a handle (13, 27), a transmission part and a blade (18), which are sequentially connected, are disposed in the head; a through hole (12) is provided at the bottom end of the head, and the blade is placed vertically above the through hole and is communicated with the through hole; a groove (23) configured to dispose the measuring scale is provided at the bottom end of the base; and the measuring scale is fixed to the inner bottom of the box body. The packaging apparatus has multiple effects of convenience in transportation and carrying, accurate measuring and cutting, cutting safety and protection and the like, and can be repeatedly used, especially, for maintenance and repair in a production site. The apparatus not only can greatly protect the personnel safety, reduce the material consumption, improve the production efficiency, and shorten down time for maintenance, but also can reduce the consumption, protect the environment and improve the economic benefits.

Abstract

Disclosed is a toothed metal framework composite gasket having irregular teeth, comprising a metal framework having tooth-shaped protrusions and a non-metallic sealing material (6), wherein multiple circles of irregular teeth curved in the direction of a pressure source are distributed radially and concentrically along upper and lower end faces of the metal framework, which are covered by a filled non-metallic sealing material. Compared with conventional sealing teeth, new moon-shaped or bow-shaped teeth provide two additional resilient points and additional flexibility, preventing stress building up at two break points at a top part and a root part of the teeth, having relatively high anti-yielding and anti-fatigue performance, and increasing the service life of the gasket. Moreover, a pressure-prevention boss (4) is designed between the irregular teeth, preventing crushing and damage of the irregular teeth caused by excessive pre-stressing force, and ensuring security of sealing. The toothed metal framework composite gasket achieves extremely large improvements in elasticity, toughness, and compression resistance, has a relatively high elastic resilience and pressure bearing capacity, and will not be crushed and does not damage a flange.

Abstract

Disclosed is a toothed metal gasket with alternating pressure-prevention steps, including concentric metal sealing teeth (1) machined on upper and lower sides of a metal framework and inclined in the direction of a pressure source, and pressure-prevention steps (2) provided on two sides of a tooth or between teeth, wherein the height of the pressure-prevention steps approaches 30%-80% of that of the teeth, and the pressure-prevention steps and the sealing teeth are covered by a filled non-metallic sealing material (4).

Abstract

An anchor-shaped connector (1) for an oil seal, the connector being comprised of an embedded portion and a groove matching the shape of the embedded portion; the embedded portion is anchor shaped, and the angle between the anchor hook and the anchor rod is less than 90 degrees. The connector of the present invention employs an anchor-shaped structure, such that an embedded piece (2) can never disengage in the circumferential direction of a ring after being embedded into the groove, thus performing reliable anchoring and permanent locking functions, avoiding connector looseness caused by repeated use, improving the sealing effect, reducing the material flexibility requirement of the split oil seal, and having wide applications.

Abstract

A fishbone inclined tooth-shaped metal gasket. Annular tooth-shaped grooves are distributed in a circumferential direction of an upper end surface and a lower end surface of the gasket. Teeth of the tooth-shaped grooves are integrally formed with the metal gasket, and are arranged oblique toward a pressure source direction. The section of the tooth-shaped grooves is in the shape of a fishbone, the angle of inclination of the teeth is more than 0 degree and less than 90 degrees, and the contact surface of the top of the teeth and a flange is not a closed angle. The top parts of the teeth are designed into a rounded angle, a flat angle, or a wave arc angle, which avoids damages to the surface of the flange caused by the conventional closed-angle teeth. The design of the inclined tooth improves the rebound resilience of the metal gasket. The tooth-shaped grooves are arranged obliquely to form a plurality of sealed pressure-resistant chambers, so that the pressure from a pressure source can be lowered level by level. The sealed chambers utilize the fluid pressure to generate an effective sealing compensation force, so as to improve the sealing reliability.
