CN201827594U - Clamp type pipeline end cover with arc surface - Google Patents

Abstract

The utility model discloses a clamp type pipeline end cover with an arc surface, which is used for plugging a port of a pipeline, and comprises a cylindrical end cover body (1), a step (2) and the sealed circular arc surface. The step (2) is arranged on an outer circle of the end cover body, the sealed circular arc surface (3) is disposed at one end of the end cover body, and an arc surface structure (4) is arranged inside the hollow end cover body (1). Compared with existing products, the clamp type pipeline end cover is portable, is small in material consumption, can reduce requirements of strength and the like on pipeline connectors when hydraulic pressure is larger in a pipeline since the end cover with the arc surface (can also be a spherical surface, a director-sphere surface or an elliptical-sphere surface according to different pressures) is deformation-resistant, and is safe and reliable.

Description

Cassette cambered surface pipeline end cap

Technical field

The utility model relates to the fluid plug members, relates in particular to a kind of end cap that is applicable to the road junction shutoff of all kinds of liquid delivery tubes.

Background technique

Liquid conducting pipes is widely used in industrial and agricultural production and the daily life.Cassette pipeline Placement is replacing the pipeline that connects with flange plate more and more widely with plurality of advantages such as simple installation, saving manufacturing expense, the flexible adjustment in permission pipeline axial gap.In pipe-line construction construction, running repairs through regular meeting the needs for working condition, require the pipeline port is carried out shutoff temporarily or permanently.(small-bore pipeline is to adopt screw plug to be tightened on the pipeline opening in the old-fashioned pipeline, and large diameter pipeline adopts solid flange plate usually or a shutoff valve shutoff directly is installed).Connect in the mode at existing cassette pipeline, be with the band screens garden cylindricality solid construction as block head, its block head end face is the plane, whole block head thickness is big, consumptive material is more.When liquid unit pressure in the pipeline is big, stressed distortion, (be out of shape for resisting, it is very thick that the top, plane will be designed) of producing greatly of flat end face.The end face on plane moves to the center of cassette pipe jointer to stress surface, causes bigger stress on pipe jointer, thereby causes pipe jointer damage or distortion easily and loss of seal, so that leak of liquid in the pipeline.

Summary of the invention

The utility model is in order to solve the technical problem of described existing block head, propose a kind of light, consumptive material is few and the cassette cambered surface pipeline end cap of resistance to deformation.

The cassette cambered surface pipeline end cap that the utility model proposes, comprise hollow cylindrical end cover body, be located at this end cover body cylindrical step, be located at the arc surface of the sealing of this end cover body one end, described end cover body is a hollow, its inside is globoidal structure.

Wherein, the globoidal structure of described end cover body inside can be for sphere, director sphere, also can be ellipsoidal surface.

The inside of described end cover body can also reinforcement gusset arranged in a crossed manner.

Compared with prior art, advantage of the present utility model is as follows:

1, light than existing product, consumptive material is few;

2, when liquid unit pressure in the pipeline is big, stress surface is moved out to outside the cassette pipe jointer, and adopts cambered surface (to follow according to different pressure, can adopt sphere, director sphere, ellipsoidal surface) end cover designs resistance to deformation can reduce the requirements such as intensity to pipe jointer, and is safe and reliable.The utility model is applicable to all metals and the nonmetal pipeline that adopts cassette pipeline Placement.

Embodiment

As shown in Figure 1 and Figure 2, be first embodiment's of the present utility model basic structure, the lonely facial canal of described cassette road end cap, it comprises columniform end cover body 1, be located at the step 2 of this end cover body cylindrical, be located at the arc surface 3 of the sealing of this end cover body left end.And end cover body 1 is a hollow, and its inside is globoidal structure 4.As required, the globoidal structure 4 of end cover body 1 inside can be set to sphere, director sphere or ellipsoidal surface.As shown in Figure 3, Figure 4, be second embodiment's of the present utility model basic structure, this embodiment's the structure and first embodiment's structure is basic identical, and difference is that the axial dimension of this end cap is longer than first embodiment's axial dimension.

As Fig. 5, Fig. 6 and shown in Figure 7, basic structure for the 3rd embodiment of the present utility model, this embodiment's the structure and first embodiment's structure is basic identical, and difference is that the inside of this end cover body 1 also intersects to be arranged with and strengthens gusset 5, to strengthen the compressive strength of product.

Sectional structure when Fig. 8 shows the utility model use promptly adopts end cap shutoff of the present utility model to have pipeline 6 ports of ring shaped slot 9.Earlier ring-shaped rubber seal ring 7 is enclosed within on the cylindrical of end cap and pipeline 6, again two Semicircular cassette pipe jointers 8 is merged clip in rubber seal 7 cylindricals, and respectively that the upper and lower end of two part-annular cassette pipe jointers 8 is fixedly connected with bolt.At this moment, the inner ring of seal ring 7 is by tightly the cylindrical that is pressed on end cap and pipeline 6, in case liquid along sealed mouth radially or axial leakage.In addition, the left and right edges of pipe jointer 8 is blocked the step 2 of end cap and the ring shaped slot 9 of pipeline 6 respectively tightly, and under the effect that prevents fluid pressure in pipeline, end cap and pipeline 6 axial separation move.

The utility model is light than existing product, and consumptive material is few; When hydraulic coupling in the pipeline is big, adopt cambered surface (can follow according to different pressure and pipe diameter, adopt sphere, director sphere, ellipsoidal surface and band reinforcement) end cover designs resistance to deformation, can reduce the requirements such as intensity to pipe jointer, safe and reliable.

Claims (3)
