Abstract

The utility model discloses a meal tube cap. According to the technical scheme, the meal tube cap mainly comprises a tube cap body; the tube cap body comprises a connecting end and a blocking end, wherein the connecting end is provided with an open channel, and the blocking end is used for sealing a pipeline; the connecting end and the blocking end are connected as a whole; the connecting end is provided with an annular groove, and an annular seal ring is fixedly embedded in the annular groove; the surface of the inner circle of the annular seal ring and the surface of the inner wall of the connecting end are arranged at the same height; the outer surface of the tube cap body is provided with a plurality of protrusions which are evenly distributed so that the tube cap body can be held conveniently. By the adoption of the technical scheme, the annular seal ring is directly arranged on the inner wall of the connecting end, therefore, when the connecting end is connected with the pipeline, gas or liquid in the pipeline can be effectively prevented from leaking through the joint between the pipeline and the tube cap body, and an operator can connect the metal tube cap to the pipeline conveniently.

Description

Metal pipe cap

Technical field

The utility model relates to a kind of mechanical part, and more particularly, it relates to the metal pipe cap in a kind of metal pipe element parts.

Background technique

Pipe cap, claim again end socket, plug, headkerchief, tube cover, silently, is welded on pipe end or is contained on the pipe end outside thread with the pipe fitting of lid plugging, is used for closing pipe line, acts on identical with pipe plug.The form of pipe cap and blind plate is close, and only blind plate is demountable shutoff, and the welding pipe cap cannot be dismantled.Pipe cap comprises the design of convex pipe cap, conical shell, reducer, flat cover and tightening mouth.

At present, the metal pipe cap on market, generally include for the connecting end be connected with pipeline and the obstruction end that plays ponding, and connecting end is connected with obstruction end one.Because pipe cap is used for closing pipe line, and pipeline is generally used for and carries gas or liquid, and on market, this pipe cap simple in structure directly is connected with pipeline, and the gas in pipeline or liquid are very easily from the joint leakage of connecting end and pipeline.

The model utility content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of metal pipe cap, and this metal pipe cap can prevent effectively that gas or the liquid in pipeline from leaking from the joint between pipeline and pipe cap.

For achieving the above object, the utility model provides following technological scheme: a kind of metal pipe cap, comprise the pipe cap body, described pipe cap body comprises with the connecting end of open channel with for the obstruction end of closing pipe line, connecting end holds one to be connected with stopping up, described connecting end is provided with annular groove, the interior fixedly embedded O-ring seal that has of annular groove, the interior ring surface of described O-ring seal and the contour setting of connecting end inner wall surface, the outer surface of described pipe cap body are provided with some being evenly distributed so that the projection gripped.

By adopting technique scheme, O-ring seal directly is set on the inwall of connecting end, when connecting end is connected with pipeline, can prevent effectively that gas or liquid in pipeline from leaking from the joint between pipeline and pipe cap, due to traditional metal pipe cap, outer surface is all smooth, and pipe cap is shorter and smaller, operator are difficult to metal pipe cap is connected on pipeline, and the setting of the projection of being convenient to grip can the easy-to-operat personnel be connected to metal pipe cap on pipeline.

The utility model further is set to: described connecting end and the joining place stopped up between end are the setting of arc surface structure.

By adopting technique scheme, the arc surface structure of joining place, relative angular structures, aesthetic property is stronger, and not like easy like that operator, the raising Safety performance of hurting of angular structures.

The utility model further is set to: the inner wall surface plating of described pipe cap body is provided with anticorrosive coat, and the outer surface plating of pipe cap body is provided with the carbon steel layer.

By adopting technique scheme, the setting of anticorrosive coat and carbon steel layer, make the pipe cap body have good decay resistance, can also improve the intensity of pipe cap body simultaneously.

The accompanying drawing explanation

Fig. 1 is the utility model metal pipe cap embodiment's structural representation;

Fig. 2 is the A section enlarged view of Fig. 1.

Embodiment

Referring to figs. 1 through Fig. 2, the utility model metal pipe cap embodiment is described further.

A kind of metal pipe cap, comprise pipe cap body 1, described pipe cap body 1 comprises with the connecting end 11 of open channel with for the obstruction end 12 of closing pipe line, connecting end 11 holds 12 one to be connected with stopping up, described connecting end 11 is provided with annular groove, the interior fixedly embedded O-ring seal 2 that has of annular groove, the interior ring surface of described O-ring seal 2 and the contour setting of connecting end 11 inner wall surface, the outer surface of described pipe cap body 1 is provided with some being evenly distributed so that the projection gripped 13.

By adopting technique scheme, O-ring seal 2 directly is set on the inwall of connecting end 11, when connecting end 11 is connected with pipeline, can prevent effectively that gas or liquid in pipeline from leaking from the joint between pipeline and pipe cap, due to traditional metal pipe cap, outer surface is all smooth, and pipe cap is shorter and smaller, operator are difficult to metal pipe cap is connected on pipeline, and the setting of the projection 13 of being convenient to grip can the easy-to-operat personnel be connected to metal pipe cap on pipeline.

Described connecting end 11 and the joining place 14 stopped up between end 12 are the setting of arc surface structure.

By adopting technique scheme, the arc surface structure of joining place 14, relative angular structures, aesthetic property is stronger, and not like easy like that operator, the raising Safety performance of hurting of angular structures.

The inner wall surface plating of described pipe cap body 1 is provided with anticorrosive coat 3, and the outer surface plating of pipe cap body 1 is provided with carbon steel layer 4.

By adopting technique scheme, the setting of anticorrosive coat 3 and carbon steel layer 4, make pipe cap body 1 have good decay resistance, can also improve the intensity of pipe cap body 1 simultaneously.
