Abstract
A planar sealing joint comprises a joint body and an annular caulking groove formed in an end surface of a connecting end of the joint body. The planar sealing joint is characterized in that an opening of the caulking groove is provided with a flange which is protruded towards the inner side of the opening. Compared with the prior art, the planar sealing joint has the advantages that the flange which is protruded towards the inner side of the opening is formed at the opening of the caulking groove, and when the planar sealing joint is actually used, a flat washer can be embedded in the caulking groove after being slightly deformed, and is naturally limited in the caulking groove by the flange at the opening, so that the flat washer is difficult to drop during transportation and use, and the planar sealing joint is quite suitable to be used actually.
Description
Technical field
The utility model relates to a kind of joint, relates in particular to a kind of plane sealing joint.
Background technique
The application of pipe joint in oil, liquid delivery line connect is very extensive, and be common like two pass joints, tee union, multiple-pass joint or the like.The sealing configuration of pipe joint, because in various pipeline connection procedures, can play seal action, such as, prevent phenomenons such as the pipeline connecting end leaks, leakage of oil, gas leakage, so, seem extremely important.The plane sealing joint is at the joint end surface caulking groove to be set, and in caulking groove, is provided with faced washer (being generally rubber system), and to form plane sealing with the pipeline end that is connected.Because the faced washer cross section is flat, surfacing and upper surface expose, and faced washer is easy to from caulking groove slippage and comes out, and all brings certain trouble for packed and transported and actual the use.Therefore, need further to improve.
The model utility content
The utility model technical problem to be solved is that its caulking groove is reasonable in design, makes the faced washer difficult drop-off to existing technology present situation and a kind of plane sealing joint is provided, and the integrity and actual use of packed and transported all had help.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this plane sealing joint; Comprise joint body and be opened in the annular caulking groove on the joint body connecting end end face, it is characterized in that: said caulking groove is provided with the flange of protrusion to the inside at opening.
Preferably, both sides all have described flange in the cross section of said caulking groove.
Compared with prior art, the advantage of the utility model is: through caulking groove is carried out structural design, make caulking groove form the circle flange of protrusion to the inside at opening; When reality is used; Faced washer can be out of shape a little and be embedded in this caulking groove, and the flange of opening is limited to faced washer within the caulking groove naturally, so; Faced washer difficult drop-off in transit and in the using process is very suitable for actual use.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the enlarged view of I portion among Fig. 1.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2, this plane sealing joint comprises joint body 1, and in the present embodiment, this joint body 1 has two connecting ends, is one or two pass joints;
On the end face of joint body 1 connecting end, offer an annular caulking groove 2, in the cross section of this caulking groove 2, the both sides that are positioned at its opening are provided with the convexity of protrusion to the inside, and form the flange 21 that a circle has effect that the faced washer card is established.
After faced washer was embedded in this caulking groove 2, the flange 21 of caulking groove 2 openings can play certain position-limiting action to faced washer, prevented that it from coming off.
Claims (2)
1. a plane sealing joint comprises joint body and is opened in the annular caulking groove on the joint body connecting end end face, it is characterized in that: said caulking groove is provided with the flange of protrusion to the inside at opening.
2. plane sealing joint as claimed in claim 1 is characterized in that: both sides all have described flange in the cross section of said caulking groove.
