Abstract
The utility model discloses a 90-degree elbow convenient to inspect, and belongs to the technical field of pipes. The 90-degree elbow comprises a 90-degree elbow body, an inspection opening and an inspection cover. The inspection opening is arranged at the bent position of the 90-degree elbow body, and the inspection cover is hermetically mounted with the inspection opening. A cylindrical protrusion is arranged in the inspection cover. The lower surface of the protrusion forms a recessed curved surface. The 90-degree elbow has the advantages that a cavity formed at the inspection opening is filled up, the curved surface formed by the protrusion of the inspection cover is in smooth butt joint with an upper curved surface of the 90-degree elbow body, and accordingly, the resistance of the inspection opening to liquid flowing is effectively reduced.
Description
Technical field
The utility model relates to pipe fitting technical field, especially relates to a kind of 90 ° of elbows being convenient to inspection.
Background technique
90 ° of elbows are a kind of conventional pipe fittings that change flow direction, are widely used in industry-by-industry.90 ° of elbows are easy to occur foul and pile up at turning, cause obstruction, when clear and coherent, need to pull down 90 ° of elbows and could get rid of obstruction, sometimes even need to destroy 90 ° of elbows and could get rid of obstruction.In order to safeguard, existing 90 ° of elbows are provided with inspection socket at bending part.Yet 90 ° of elbows as shown in Figure 1, comprise 90 ° of bend pipes 11, inspection cover 12, inspection socket 13.The cavity 14 existing at inspection socket 13 places, the mobile resistance that produced to liquid, easily causes foul to pile up.
Therefore, a kind of inspection socket that can effectively reduce brings checkable 90 ° of elbows of resistance just to become and extremely needed.
Model utility content
The utility model provides a kind of 90 ° of elbows being convenient to inspection, hinders the problem of flow of fluid to solve inspection socket of the prior art.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of 90 ° of elbows being convenient to inspection, the inspection cover that comprises 90 ° of bend pipes, is positioned at the inspection socket of 90 ° of bend pipe bending parts, installs with inspection socket sealing, the inside of described inspection cover has cylindrical bump, the lower surface of described projection forms concave curvatures, when inspection cover is fixedly installed in inspection socket place, this concave curvatures has been filled up the breach at 90 ° of bend pipe inspection socket places, smoothly docks with 90 ° of bend pipe curved surfaces.
As preferred technological scheme, between described inspection socket and inspection cover, adopt engage thread to be connected.
As preferred technological scheme, described cylindrical bump is arranged on the center of inspection cover.
As preferred technological scheme, at described inspection socket, place is provided with sealant layer.
The beneficial effect the utlity model has is: filled up the cavity that inspection socket place exists, the curved surface that inspection cover convexes to form smoothly docks with 90 ° of elbow body top-surface cambers, has effectively reduced the resistance that inspection socket comes to liquid fluxion strap.
Accompanying drawing explanation
In order to be illustrated more clearly in embodiment of the present invention or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic cross-section that prior art can be checked elbow.
Schematic cross-section when Fig. 2 a is not fastening lid of the present utility model.
Schematic cross-section when Fig. 2 b is the utility model fastening lid.
Wherein: 1-90 ° of bend pipe, 2-inspection cover, 3-inspection socket.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 2 a, Fig. 2 b, a kind of 90 ° of elbows being convenient to inspection, include 90 ° of bend pipes 1, inspection socket 3 and inspection cover 2.Inspection socket 3 is positioned at the bending part of 90 ° of bend pipes 1, and inspection socket 3 is provided with inspection cover 2.The bottom centre of inspection cover 2 the insides has cylindrical bump, the lower surface of projection forms concave curvatures, when inspection cover is fixedly installed in inspection socket 3 place, this concave curvatures has been filled up the breach at 90 ° of bend pipe 1 inspection socket 3 places, with the 1 curved surface smooth connection of 90 ° of bend pipes, inspection socket 3 is connected by engage thread with inspection cover 2, and in order further to reach the object of sealing, 90 ° of bend pipe 1 jointing internal surfaces have sealant layer.
The utility model has been filled up the cavity that inspection socket forms effectively, has reduced the resistance of inspection socket to flow of fluid.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
