Abstract
The utility model relates to a joint in the pipeline, in particular to pipeline joint of area viewing aperture, including the cavity casing, be equipped with at the both ends of casing and be used for with the interface of pipe connection, be equipped with at the side of casing with interface axis looks vertically projection, be equipped with on the projection with the communicating through-hole of casing cavity in, be equipped with the clear glass board in the port department of through-hole, the outside screw fastening of projection has the cyclic annular fixed lid that is used for fixed glass board, its characteristics are: the outer end of the through hole of the convex column is a conical inclined plane which is open outwards, a sealing element is arranged on the conical inclined plane, the peripheral sides of the glass plates are correspondingly set to be conical inclined planes, and the glass plates are sleeved in the through hole and are matched with the through hole to form the conical inclined plane. Because the glass plate and the through hole are matched by the conical inclined plane, the glass plate is screwed more and more tightly when the fixing cover is screwed, so that the sealing element is pressed tightly to ensure that the sealing element is more reliable in sealing, the sealing element can bear large medium pressure, and the sealing performance is greatly improved.
Description
Technical field
The utility model relates to a kind of ducted joint, particularly a kind of pipe coupling with observation panel.
Background technique
In pipeline, for the ease of observing the real-time status of medium, fairly simple effective way is to offer observation panel in pipe coupling, the pipe coupling of present band observation panel its structure usually is such: establish screw thread at the two ends of a cylindrical tube and be used for connecting tube, side at cylindrical tube vertically is provided with boss, boss is provided with the port that communicates with the body runner, at boss loam cake one transparency glass plate, establish seal ring on the glass plate, and then the upward fixed cover that spins, be used for making the glass plate sealing and fixing, and since glass plate be flat cover on the end face of boss, therefore under the big situation of pressure medium, sealing can not guarantee, cause leakage easily, in addition, medium also is trapped in the space of boss (this section space between the passage of the following port of glass plate and body) easily, particularly is directed to and glues shape medium or mounting medium, especially easily accumulate interior, thus the health that influence is used and the observation of observation panel.
Summary of the invention
The purpose of this utility model provides a kind of and bears big pressure medium and can guarantee to make the pipe coupling of the band observation panel of sealability.
Thereby further purpose of the present utility model provides and a kind ofly is difficult for that medium is accumulated and makes it use the pipe coupling of the band observation panel of health more.
The purpose of this utility model is achieved by the following technical solution: a kind of pipe coupling with observation panel, comprise hollow casing, be provided with at the two ends of housing and be used for the interface that is connected with pipeline, side at housing is provided with and the perpendicular projection of interface axis, projection is provided with the through hole that communicates with the housing inner cavity, port at through hole is provided with transparency glass plate, outside screw at projection is fastened with the ring-type fixed cover that is used for fixing glass plate, be characterized in: the outer end of the through hole of described projection is outwardly open awl inclined-plane, on the awl inclined-plane, be provided with Sealing, the corresponding awl inclined-plane that is made as of all sides of described glass plate, glass plate are set in the through hole and constitute the awl inclined-plane with through hole and cooperate.Because glass plate adopts the awl inclined-plane to cooperate with through hole, therefore when screwing on fixed cover, can make glass plate revolve tighter and tighter, make Sealing sealing more reliable thereby tightly push down Sealing, also make Sealing can bear big pressure medium, greatly improved sealability.
Further, between the upper-end surface of glass plate and fixed cover, also be provided with the polythene seal ring, utilize the polythene seal ring to make fixed cover directly not contact, thereby neither can damage glass cover, further play sealing again and do with glass plate.
Further purpose of the present utility model is achieved by the following technical solution: the interface of housing and the joint of projection are made as sphere, and the relevant position of the inner cavity of corresponding housing also is spherical.Adopt the spherical transition to make medium to flow away from jointing, and can not accumulate through hole, both guaranteed the health that joint uses effectively, also be difficult in addition stopping up observation panel and influence observation at projection along this sphere.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation
Embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
By as can be known shown in Figure 1, the embodiment of a kind of pipe coupling with observation panel of the utility model, comprise hollow casing 1, be provided with at the two ends of housing and be used for the interface 12 that is connected with pipeline, side at housing 1 is provided with and the perpendicular projection 13 of interface 12 axis, projection 13 is provided with the through hole 14 (being peep hole) that communicates with housing inner cavity 11, be provided with transparency glass plate 4 in the port of through hole 14, outside screw at projection 13 is fastened with the ring-type fixed cover 2 that is used for fixing glass plate 4, the outer end of the through hole 14 of described projection 13 is outwardly open awl inclined-plane 131, be provided with Sealing 3 on awl inclined-plane 131, the corresponding awl inclined-plane 41 that is made as of all sides of described glass plate 4 is set in formation awl inclined-plane cooperation with it in the through hole 14.Because glass plate 4 adopts awl inclined-plane 14 to cooperate with through hole, therefore when screwing on fixed cover 2, can make glass plate 4 revolve tighter and tighter, make Sealing sealing more reliable thereby tightly push down Sealing 3, also make Sealing can bear big pressure medium, greatly improved sealability.
In the utility model, between the upper-end surface of glass plate 4 and fixed cover 2, also be provided with polythene seal ring 5, utilize polythene seal ring 5 to make fixed cover 2 directly not contact, thereby neither can damage glass cover, further play seal action again with glass plate 4.
In the illustrated implementation column, also the interface 12 of housing 1 and the joint 15 of projection 13 are made as sphere, the relevant position of the inner cavity of corresponding housing also is spherical.Adopt spherical 16 transition to make medium to flow away from jointing, and can not accumulate through hole 14 places, both guaranteed the health that joint uses effectively, also be difficult in addition stopping up observation panel and influence observation at projection 13 along this spherical 16.
Observation panel in above-mentioned be generally two symmetrically arranged, certainly, promptly only establish projection in a side of housing if only establish one, establish through hole and glass plate and fixed cover on the projection also certainly within the utility model protection domain.
