Embodiment Construction

[0021] like figure 1 As shown, the traditional sealing method is achieved by placing a traditional gasket 4 between the rigid body 1 and the cover plate 2 and pressing it with the bolt 3 . Since the entire gasket is placed between the rigid body 1 and the cover plate 2 through all the bolts, after compression, what can be closed is only around the bolts and along the contact surface, and cannot form a closed-loop sealing system. When subjected to changes in temperature, humidity and working environment and pressure conditions, liquid or gas can seep out through thread gaps and other convex and concave gaps.

[0022] Rigid contact channel inserts or injection seals, such as figure 2 As shown, the structure is that the same number of annular semicircular passages 6 encircling the fastening bolts and the straight semicircular passages 5 connected therewith are arranged on the contact surfaces of the rigid body 1 and the cover plate 2, forming a circular passage and A closed-lo...

Abstract

The invention relates to a ring embedding or glue injecting sealing method for a rigid touch surface channel. The method is characterized by setting a plurality of annular semi-circle channels and straight line semi-circle channels which are communicated and same in number of ring fastening bolts on two sealed touch surfaces to form a closed loop system of which the annular channel and the straight line channel are communicated completely; or setting same and completely communicated touch surface closed ring semi-circle channels on the two sealed touch surface, wherein the annular rigid body and cover plate of the channels are positioned along an opening but are away from the fastening bolts, after the butt joint of the rigid body and the cover plate on each touch surface, two integral channels which are communicated completely are formed, and the channels ensures that a glue injection inlet is communicated with an air leakage opening. The channels are subjected to ring imbedding or glue injecting to form two favorable closed ring sealing systems, and the effect is safe and reliable.

Description

1. Technical field: [0001] The invention belongs to mechanical devices 2. Background technology: [0002] The basic requirement for the quality of oil-water-gas devices such as vehicle engines, diesel engine high-pressure pumps, transmission boxes, oil pumps, air pumps, water pumps, and hydraulic equipment is good sealing. However, the traditional sealing method, that is, the O-shaped rubber ring and Sealing methods such as asbestos gaskets are limited by structure and method. Often when subjected to changes in temperature, humidity, working environment and pressure conditions, the so-called gaskets will be deformed, deteriorated, and ineffective. Moreover, due to the traditional sealing method What actually works is the compression of the points and lines on the interface between the seals, and over time failure and leakage are inevitable. 3. Contents of the invention: [0003] The rigid contact surface channel insert ring or glue injection sealing method of the present ...
