Description
Technical field
The utility model relates to a kind of connected element of pipeline, particularly relates to a kind of flange cover.
Background technique
Flange cover is the seal closure of a kind of safety effect in fact.The liquid in some chemical plant or laboratory or gas are carried all and are connected with pipeline, and the interface position of pipeline has been grown or plug into and tightly can not cause leakage, consequence may cause that personnel are poisoning to be damaged health service time.
Summary of the invention
The purpose of this utility model is exactly for the problems referred to above, and a kind of flange cover is provided.
For achieving the above object, the utility model adopts following technological scheme:
A kind of flange cover, formed by two transparent symmetrically arranged half of flange covers, one of them half of flange cover is hemicycle cylindrical shell, its opening end is provided with the edge protruding to open outer side, the junction surface at the edge of this protrusion is plane, the hull outside two ends of hemicycle cylindrical shell axial direction are provided with semicircle connecting tube, semicircle connecting tube is communicated with the cavity of hemicycle cylindrical shell inner side, two semicircle connecting tubes are on same axis, on junction surface, be at least provided with four screw connecting holes, the opening end of two half of flange covers relatively fastens and is tightly connected.
The junction surface of the opening end of two described half of flange covers is provided with sealing gasket.
The madial wall of described semicircle connecting tube is provided with seal groove, is provided with seal ring in seal groove.
Described half of flange cover is transparent plastic.
The beneficial effects of the utility model: the utility model provides a kind of flange cover, be fastened on pipe joint and can seal with two reciprocity semicircle transparent covers, can there is the inside in the object leaking, allow staff find in time to leak, on-call maintenance, avoid the generation of potential safety hazard, play prevention and security insurance effect effectively.
Brief description of the drawings
Fig. 1 is one of them embodiment's of the utility model front schematic view.
Fig. 2 is the schematic top plan view of Fig. 1.
Fig. 3 is the schematic perspective view that the utility model parts decompose.
Fig. 4 is the schematic perspective view that the utility model is connected with pipeline.
Embodiment
As shown in Figure 1 to Figure 3, the utility model is made up of two transparent symmetrically arranged first flange cover 1 and second flange covers 2, first flange cover 1 is identical with second flange cover 2 structures, be symmetrical arranged up and down, wherein second flange cover 2 is hemicycle cylindrical shell 21, the face shaping that is housing parts is columniform half, inside is semicircle cavity 211, its opening end is provided with the edge 23 protruding to open outer side, edge is set and is convenient to the relative connection of left half flange cover 1 and right half flange cover 2, the junction surface at the edge of this protrusion is plane, because junction surface increases, be more convenient for being tightly connected, prevent from revealing.Hull outside two ends on the axis of hemicycle cylindrical shell are provided with semicircle connecting tube, i.e. front connecting tube 22 and rear connecting tube 24, front connecting tube 22 and rear connecting tube 24 are on same axis, the junction surface at the edge of hemicycle cylindrical shell, protrusion and two semicircle connecting tubes are connected as a single entity, on junction surface, be at least provided with four screw connecting holes 231, the joint that in use left half flange cover 1 and right half flange cover 2 is fastened on to pipeline is sealedly connected relative the opening end of two halves flange cover fastening by screw.
The junction surface of the opening end of described two halves flange cover is provided with sealing gasket.The madial wall of described semicircle connecting tube is provided with seal groove, is provided with seal ring in seal groove.Described half of flange cover is transparent plastic, can select transparent plastic one wherein, and this transparent plastic adopts different plastics according to different Environmental Conditions, and the leakage thing that the plastics that use can not be possible with pipeline reacts.Described plastics can be thermoplastic, as, plexiglass (PMMA), polycarbonate (PC), polyethylene terephthalate, nylon etc., also can adopt thermosetting plastics, as phenolic plastic, epoxy and unsaturated polyester etc.
As shown in Figure 4, the utility model is in use that the joint that left half flange cover 1 and right half flange cover 2 are socketed in to pipeline is used, cover on the jointing of pipeline 3, leak the object leaking can be existed in semicircle cavity 211 if occur, because the transparent staff of allowing can find to leak in time, thus the generation of on-call maintenance Accident prevention.
The utility model is not limited to described implementation methods, under the model utility design that does not exceed claim, for the personnel with the ABC in field under the utility model, can implement a lot of distortion, and these modification also belong to scope of the present utility model.
