Be provided with a lid with matching, the lid is made up of vulcanie, be additionally provided with multiple connecting screw holes on lid, connecting screw hole with
Be centrosymmetric distribution centered on the center of circle of lid, and an observation port is additionally provided with the center of lid, and observation port is provided with a glass
Plane where piece, sheet glass and the top surface flush of lid, a pair of grooves are additionally provided with the edge of lid, and groove is with the circle of lid
Be centrosymmetric distribution centered on the heart, and the edge that sheet glass is arrived at from the outer wall other end of lid is played in one end of groove.
Used as preferred embodiments of the present invention, described sheet glass is double-decker safety glass piece.
It is argon arc welding as preferred embodiments of the present invention, between described connecting tube and W.N flange.
The lid of flat cover lining stainless steel hand hole of the invention does not make of metal material but is made of vulcanie, should
It is also provided with peep hole and sheet glass on lid, the lid that elastomeric material is made can be directly mutually close with ring flange on hand hole
Close, without setting rubber washer on flange or on lid in addition, so as to enormously simplify the structure of hand hole, improve production
Efficiency.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the dimensional structure diagram that flat cover of the invention serves as a contrast stainless steel hand hole.
Specific embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
