Abstract

The utility model discloses a pipe fitting for pipe connection and particularly relates to a ring-squeezing-type high-pressure water mist pipe fitting, which comprises a pipe body (1) and a connecting part (2) which is arranged on the pipe body (1). A sealing groove (3) and ring squeezing grooves (4) which are in parallel with each other are arranged on the outer wall of the connecting part (2). The ring-squeezing-type high-pressure water mist pipe fitting has the effects that since the sealing groove and the ring squeezing grooves are arranged on the outer wall of the pipe fitting, after the pipe fitting is sheathed into the mouth of a pipe, the pipe can be fully deformed with the ring squeezing grooves when a ring squeezing tool is used for ring squeezing and the joint can be ensured to capably bear delivery pressure; and since the sealing groove and a sealing ring are added between the ring squeezing grooves, the sealing effect of the joint is further improved.

Description

Ring pressure type heavy pressure fine spray pipe fitting

Technical field

The utility model relates to a kind of pipeline connection and uses pipe fitting, is specifically related to a kind of ring pressure type heavy pressure fine spray pipe fitting.

Background technique

At present, a large amount of stainless steel pipeline that use in the feedwater fire protection pipeline, because this class stainless steel pipeline tube wall is thinner, usually adopting ring to press connects, promptly by ring-pressing tool with the inwall of stainless steel pipeline be connected together with the outer wall mutual extrusion of pipe fitting, form certain sealing and fastening, but when the pressure medium of carrying in the pipeline is very high, need the wall thickness of pipe fitting and steel pipe to reach certain degree ability pressure-resistant, in the prior art, the ring that does not also have ring-pressing tool can finish blocked up pipe fitting of tube wall and steel pipe is pressed, and causes also not having very to encircle effectively the pressure mode in the high pressure pipe line field and satisfies its requirement to the joint sealing.

The model utility content

The utility model has overcome the deficiencies in the prior art, and a kind of ring pressure type heavy pressure fine spray pipe fitting is provided, and solves present ring-pressing tool and can't adopt the problem that the pressure mode is connected of encircling with pipeline to the blocked up pipe fitting of tube wall.

For solving above-mentioned technical problem, the utility model by the following technical solutions:

A kind of ring pressure type heavy pressure fine spray pipe fitting comprises the body and thereon the connection part of position of pipe fitting the seal groove and the ring indent that are parallel to each other being arranged on the outer wall of connection part.

Further technological scheme is:

Stud with seal ring in the above-mentioned seal groove.

Above-mentioned ring indent has two at least, is evenly distributed on the seal groove both sides.

Above-mentioned body can be any in the straight-through pipe fitting of straight-through tube, bend pipe tools, tee pipe fitting, four-way pipe fitting, reducing, reducing bend pipe fitting, reducing tee pipe fitting, the reducing cross pipe fitting.

Compared with prior art, the beneficial effects of the utility model are: because prefabricated seal groove and ring indent on the connection part outer wall of pipe fitting, when being connected with pipeline, when its ring being pressed pipeline fully is out of shape with the ring indent with ring-pressing tool, can bear the pressure of very high fed sheet of a media to guarantee this joint, between the ring indent, set up seal groove and seal ring in addition, further improve the sealing effect of joint.

Among the figure: 1 is body, and 2 is connection part, and 3 is seal groove, and 4 are the ring indent, and 5 is seal ring.

Embodiment

Below in conjunction with accompanying drawing the utility model is further elaborated.

As shown in Figure 4, a kind of ring pressure type heavy pressure fine spray pipe fitting is provided, the body 1 of pipe fitting is a tee pipe fitting, connection part 2 on it is three places, the seal groove 3 and the ring indent 4 that are parallel to each other are arranged on the outer wall of every place connection part 2, stud with seal ring 5 in the seal groove 3, seal groove 3 is one, ring indent 4 is two, and ring indent 4 is evenly distributed on seal groove 3 both sides.

As shown in Figure 5 and Figure 6, pipeline is enclosed within on the utility model outer wall when mounted, with ring-pressing tool pipeline and ring indent 4 connection part relevant positions are compressed again, pipeline fully is out of shape with the ring indent, when the pipeline into ring indent 4 that caves in, can play fastening effect, and when compressing, encircle indent 4 meeting crush seal grooves 3 inner seal rings 5, play extraordinary sealing effect.

When the connection pipe fitting body was other structure, Placement was consistent with such scheme, was described so enumerate embodiment no longer separately.Its connection pipe fitting main body structure is as follows:

The connection pipe fitting body is that as shown in Figure 1, its connection part 2 is two places when leading directly to pipe fitting, is provided with seal groove 3 and ring indent 4 on the outer tube wall at every place.

When the connection pipe fitting body was bend pipe tools, as shown in Figure 2, its connection part 2 was two places, and the outer tube wall at every place is provided with seal groove 3 and ring indent 4.

When the connection pipe fitting body is four-way pipe fitting, structure as shown in Figure 3, its connection part 2 is for everywhere, the outer tube wall at every place is provided with seal groove 3 and ring indent 4.

When the connection pipe fitting body of the technical program is the similar pipe fitting of the straight-through pipe fitting of reducing, reducing bend pipe fitting, reducing tee pipe fitting, reducing cross pipe fitting or other, still in the protection domain of present specification.
