Abstract
The invention discloses a positioning type port gasket for an exhaust pipe. The positioning type port gasket for the exhaust pipe comprises a gasket body; four elliptic exhaust holes are arranged in the gasket body; two exhaust holes in the left side and the right side are respectively connected with the two exhaust holes in the middle through short connecting plates, wherein the two exhaust holes in the middle are connected through long connecting plates; a rectangular positioning gap is arranged in each short connecting plate; a small blind hole is arranged in each long connecting plate; a mounting hole, a sunken-side positioning hole and a small blind hole are respectively arranged in the upper end of each exhaust hole; another mounting hole and another small blind hole are respectively formed in the lower end of each exhaust hole. According to the positioning type port gasket for the exhaust pipe, two symmetric rectangular positioning gaps are used for positioning, so that the positioning is accurate; the sunken-side positioning holes and the mounting holes are mixed in use, so that the stability of the gasket is improved.
Description
Technical field
The present invention relates generally to pad field, particularly relates to a kind of location type exhaust port pad.
Background technique
Pad (gasket) is the mechanical seal between two objects, usually to be under pressure between prevent two objects, burn into and pipeline expand with heat and contract with cold leakage naturally.Because machining surface can not be perfect, pad is used to fill up irreqularity.Be generally that a shim body has multiple hole in prior art, manufacturing process is complicated.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of location type exhaust port pad.
The present invention is achieved by the following technical solutions:
A kind of location type exhaust port pad, include shim body, it is characterized in that: shim body is provided with four oval exhaust ports, left, two exhaust ports on right both sides are connected by there being short connecting plate with two exhaust ports of centre respectively, connected by long connecting plate between two middle exhaust ports, each short connecting plate is respectively equipped with a rectangle locating notch, long connecting plate is provided with a small blind hole, the upper end of each exhaust port is respectively equipped with a mounting hole, a heavy limit positioning hole, a small blind hole, the lower end of each exhaust port is respectively equipped with a mounting hole, a small blind hole.
Advantage of the present invention is:
The present invention is positioned by the rectangle locating notch of two symmetries, registration, and heavy limit positioning hole, mounting hole are used in combination, make good stability of the present invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of location type exhaust port pad, include shim body 1, shim body 1 is provided with four oval exhaust ports 2, left, two exhaust ports 2 on right both sides are connected by there being short connecting plate 3 with two exhaust ports 2 of centre respectively, connected by long connecting plate 4 between two middle exhaust ports 2, each short connecting plate 3 is respectively equipped with a rectangle locating notch 5, long connecting plate 4 is provided with a small blind hole 6, the upper end of each exhaust port 2 is respectively equipped with a mounting hole 7, a heavy limit positioning hole 8, a small blind hole 9, the lower end of each exhaust port 2 is respectively equipped with a mounting hole 10, a small blind hole 11.
