Abstract
A two-way explosion-protection fiberglass reinforced plastic (FRP) view mirror with an internally-threaded flange is provided, which related to a two-way explosion-protection FRP view mirror used in pipelines. The two-way explosion-protection FRP view mirror at least comprises an explosion-protection glass view mirror cover and is characterized in that the explosion-protection view mirror glass cover and explosion-protection view mirror glass are connected on a view mirror body by means of mechanical seal; and a sealant, the explosion-protection glass lower view mirror cover and the explosion-protection view mirror glass are connected on the view mirror body by means of mechanical seal. The invention employs the internally-threaded flange special for pipeline connection with compact structure; can observe the flows of two media (one inlet medium and the other outlet) in the pipeline; and is widely used in various liquid vessels (such as oil pipes and water pipes) and equipment pipelines, particularly anti-corrosive pipelines.
Description
Technical field:
The present invention relates to the explosion-proof glass reinforced plastic viewing mirror on a kind of pipeline, installing/dismounting explosion-proof glass reinforced plastic viewing mirror device very easily on small-bore pipeline.
Background technique:
At present, the known handleless cup of looking is by visor body, clear glass, sealing material, sealing material gland, and installing/dismounting is pretty troublesome on small-bore pipeline.
Summary of the invention:
The purpose of this invention is to provide a kind of inner screw flange two-way explosion-proof glass reinforced plastic viewing mirror.
Technological scheme: the object of the present invention is achieved like this, a kind of inner screw flange two-way explosion-proof glass reinforced plastic viewing mirror, it is characterized in that anti-explosion glass gland of visor and the anti-explosion glass of visor are sealedly connected on the inner screw flange two-way explosion-proof glass reinforced plastic viewing mirror body by bolt machinery, sealing gasket, lower cover, be sealedly connected on the inner screw flange two-way explosion-proof glass reinforced plastic viewing mirror body by bolt machinery
Technique effect: owing to adopt such scheme, the one-in-and-one-out of pipeline see two logical rate-of flow purposes.Be widely used on various liquid traps such as oil pipe, water pipe and the equipment pipe particularly on the deep-etching pipeline.
Description of drawings:
The present invention is further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is a longitudinal sectional drawing.
The anti-explosion glass gland of 1 visor among the figure, 2 bolts, 3 visors are prevented explosion glass, 4 sealing gaskets, 5 inner screw flange two-way explosion-proof glass reinforced plastic viewing mirror bodies, 6 sealing gaskets, 7 visors are prevented explosion glass, 8 lower covers, 9 bolts.
Embodiment:
In the drawings: the anti-explosion glass gland 1 of visor is connected on the inner screw flange two-way explosion-proof glass reinforced plastic viewing mirror body 5 by bolt 2 mechanical seals with anti-explosion glass 3 sealing gaskets 4 of visor.The anti-explosion glass gland 8 of 6 times visors of sealing gasket is sealedly connected on the inner screw flange two-way explosion-proof glass reinforced plastic viewing mirror body 5 by the anti-explosion glass machinery of visor under bolt 9 handles.Owing to adopt such scheme, the one-in-and-one-out of pipeline see two logical rate-of flow purposes.
Claims (1)
