Abstract
The utility model discloses a joint connecting device, which comprises a first joint, a second joint and a sealing ring, wherein the outer wall of the second joint is provided with a groove; a limiting part is arranged between the first joint and the second joint; the second joint is inserted into the first joint; and the sealing ring is arranged in the groove, and is in interference fit with the inner wall of the first joint. The joint connecting device has a simple structure and high airtightness, and is convenient to detach.
Description
Technical field
The utility model relates to a kind of connection set, particularly a kind of joint connection.
Background technique
Joint connection is very common in the middle of the connection of pipeline, is threaded as common employing of the movable joint of existing valve body or water pipe, and reaches the purpose of sealing by screw thread.
Owing to valve body adopts screw connection structure, thread joint face winding raw meal belt or the filling thread locking adhesive at valve body and joint is connected with promotion usually, reaches the purpose of sealing simultaneously.Because valve body and joint employing thread connecting mode, the position screw thread that is difficult to guarantee to reach designing requirement during urgent screw thread is just urgent; This process is prone to screw thread and breaks, beats situations such as not tight, thereby causes refrigerant leakage, is difficult to reach the better seal effect, and operating difficulties; In case thread damage, even maintenance, replacing have been carried out in the regular screw threads loose joint, but the screw thread that has worn and torn still affects the sealing effect of valve body.
In the production assembly process of valve body, need on flank of thread, twine raw meal belt, this operation is more loaded down with trivial details, influences manufacturing efficiency; If use the mode of filling thread locking adhesive, yet this kind connection is non-dismountable, and joint can not use repeatedly, is unfavorable for after-sales service and replacing.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, good airproof performance, the joint connection of convenient disassembly.
Its technological scheme is as follows: a kind of joint connection, comprise first joint, second joint, also include seal ring, outer wall at second joint is provided with groove, has limited part between first joint and second joint, second joint inserts in first joint, seal ring place in the groove and with the inwall interference fit of first joint.
The technological scheme of the further refinement of aforementioned techniques scheme can be.
Described groove is square groove, circular groove or vee gutter.
Described limited part is the first spacing end face and the second spacing end face that is arranged on second joint that is arranged on first joint, and the first spacing end face contacts with the second spacing end face, and the first spacing end face and the second spacing end face all outwards protrude and form boss.
Connect by link between the described first spacing end face, the second spacing end face.
Described link is cutting ferrule or attachment screw.
Described joint is pipe joint or valve body interface.
Replacement scheme as aforementioned schemes, groove can be located at the inwall of first joint, this scheme is: a kind of joint connection, comprise first joint, second joint, also include seal ring, be provided with groove, have limited part between first joint and second joint at the inwall of first joint, second joint inserts in first joint, seal ring place in the groove and with the outer wall interference fit of second joint.
In sum, the utility model has the advantages that:
1, adding man-hour, need not to process connecting thread, manufacturing process is simple.
2, when dismounting or installation, more convenient operation, when connection was arranged, joint can use continuously.
3, avoided in the conventional construction, connected the damage produced, and need not beat glue, good airproof performance when connecting by connecting thread.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Extremely shown in Figure 2 as Fig. 1, a kind of joint connection, comprise first joint 1, second joint 2, also include seal ring 5, outer wall at second joint 2 is provided with groove 3, (limited part is the first spacing end face 6a and the second spacing end face 6b that is arranged on second joint that is arranged on first joint to have limited part between first joint 1 and second joint 2, the first spacing end face 6a contacts with the second spacing end face 6b, the first spacing end face 6a and the second spacing end face 6b all outwards protrude and form boss), second joint 2 inserts in first joint 1, seal ring 5 place in the groove 3 and with the inwall interference fit of first joint 1.
Wherein, connect by link (as cutting ferrule or attachment screw) between the described first spacing end face 6a, the second spacing end face 6b, to strengthen the connective stability of first joint 1 and second joint 2.The joint of present embodiment is pipe joint or valve body interface.
The assembly method of present embodiment is: at first seal ring 5 is assemblied on the outer groove 3 of second joint 2, second joint 2 and first joint 1 that will block seal ring 5 then assemble, progressively screw two joints, fit until the first spacing end face 6a of first joint 1, the second spacing end face 6b of second joint 2, by link the first spacing end face 6a, the second spacing end face 6b are connected again.
Present embodiment has following advantage, and 1, adding man-hour, need not to process connecting thread, manufacturing process is simple; 2, when dismounting or installation, more convenient operation, when connection was arranged, joint can use continuously; 3, avoided in the conventional construction, connected the damage produced by connecting thread, and need not play glue when connecting, seal ring 5 is interference fit, good airproof performance with groove 3 and inner nosepiece wall.
Another kind of embodiment of the present utility model is, groove 3 is located at the inwall of first joint 1, as shown in Figure 3, a kind of joint connection, comprise first joint 1, second joint 2, also include seal ring 5, inwall at first joint 1 is provided with groove 3, first joint 1 and second joint, 2 opposing end faces are the first spacing end face 6a, the second spacing end face 6b, second joint 2 inserts in first joint 1, seal ring 5 place in the groove 3 and with the outer wall interference fit of second joint 2, the first spacing end face 6a contacts with the second spacing end face 6b.
Only be specific embodiment of the utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection domain of the present utility model.
