Description
Technical Field
The utility model relates to a pipeline pipe fitting seals the field, concretely relates to small-size pipeline pipe fitting high-speed joint seal structure.
Background
The pipe fitting threaded joint is a part for realizing the quick installation of functional leading-in and leading-out of a conveying pipeline. The connecting device is commonly used for connecting pipelines in daily home decoration, or other devices such as a hydraulic system and an air supply system for connecting hydraulic equipment.
The conventional small-sized pipeline pipe fitting introduction and derivation connection usually adopts threaded connection, but a gap exists at the connection part of the threaded connection, so that the phenomenon of leakage is easy to occur. In order to avoid water leakage and air leakage of the pipe fitting threaded joint, a raw material belt is usually wound on the threaded connection part of the pipe fitting for sealing, the winding amount of the raw material belt is difficult to control, and if the winding amount of the raw material belt is too small, the compactness of the raw material belt is low, and the leakage phenomenon is still easy to occur; if the winding amount of raw material area is too high, the closely knit degree of raw material area is great, thickness is thicker, and the screw thread is comparatively arduous when screwing in, and pipe fitting screwed joint installation is difficult and waste time and energy.
In view of the above, the applicant has conducted an intensive study on the above problems, and has developed a rapid connection sealing structure according to the present invention.
Disclosure of Invention
The utility model discloses a main aim at provides a small-size pipeline pipe fitting high-speed joint seal structure, can install the quick sealing connection of pipe fitting screwed joint to simple structure, sealing performance is strong.
In order to achieve the above purpose, the solution of the present invention is:
the utility model provides a small-size pipeline pipe fitting high-speed joint seal structure, includes the connecting piece, wherein, the front end of connecting piece has screw thread portion direction, the nearly front end of screw thread portion is equipped with the arc caulking groove, the embedded sealing washer that is equipped with of arc caulking groove.
Furthermore, the length of the thread part at the rear end of the arc caulking groove is greater than that of the thread part at the front end of the arc caulking groove.
Furthermore, the bottom of the caulking groove is an arc-shaped bottom, and the cross section of the sealing ring is a circular section.
Further, the cross section width of the sealing ring is larger than or equal to the thread pitch of the thread part.
Furthermore, the sealing ring is made of nitrile rubber.
After adopting above-mentioned structure, during the use, can overlap the sealing washer in the arc caulking groove of screw thread portion earlier and then connect this pipe fitting screw in helicitic texture. Compared with the prior art, beneficial effect lies in, one of which, this novel nitrile rubber sealing washer that adopts replaces the raw material area to seal threaded connection department, can reach quick sealing connection's effect, need master the quantity that the raw material area used if using raw material area seal installation, just can guarantee the leakproofness. The sealing connection structure can be directly installed only by matching the rubber ring on the inner sleeve of the arc caulking groove. The sealing connection is more convenient, rapid and easy to operate. Secondly, this is novel sets up the sealing washer near the front end for screw thread portion reaches sealed purpose more easily when screw in working element. Thirdly, this novel simple structure, repeated dismouting is used many times, reduces use cost. Convenient processing and is suitable for mass production. Fourthly, this neotype sealing washer that uses adopts nitrile rubber to make, and nitrile rubber is software elastic rubber, takes place extrusion deformation inflation easily when receiving the screw thread extrusion, fully fills the screw thread to improve sealed effect.

Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
As shown in fig. 1-2, a quick connection sealing structure for small-sized pipeline fittings comprises a connecting piece 1, wherein the connecting piece 1 is in a circular tube shape and is used for being connected with a pipeline. The front end of the connecting piece 1 has a thread 2, which protrudes outwards, and the outer circumference of the thread 2 has an external thread 3, which external thread 3 is intended for a mating threaded connection with a working element. The near front end of screw thread portion 2 is equipped with arc caulking groove 4, and arc caulking groove 4 sets up around the outer periphery of screw thread portion 2, and the screw thread of the near front end of arc caulking groove 4 can assist the guide and facilitate the installation to be used for the fixed mounting of sealing washer 5. When the sealing ring is used, the sealing ring 5 is firstly sleeved in the arc-shaped caulking groove of the thread part 2, and then the thread part 2 is screwed into the working element for connection. This novel adoption nitrile rubber sealing washer 5 replaces the thread connection department to seal, can reach quick sealing connection's effect, uses convenient and fast more. And this novel connection seal structure's simple structure only needs one arc caulking groove 4 of front end processing at screw portion 2 can cooperate with sealing washer 5, and convenient manufacturing is fit for mass production.
Preferably, the length of the threaded portion 2 at the rear end of the arc caulking groove 4 is greater than the length of the threaded portion 2 at the front end of the arc caulking groove 4, and in this embodiment, the arc caulking groove 4 may be disposed at the rear end of the second turn of the thread at the front end of the threaded portion 2. After adopting above-mentioned structure, when screw thread portion 2 just started the screw in, sealing washer 5 can realize sealed with thread fit, makes this novel seal structure can reach sealed effect more easily.
Preferably, the bottom of the arc caulking groove 4 is arc, and the cross section of the sealing ring 5 is a circular section matched with the bottom of the arc caulking groove. After adopting above-mentioned structure for installation in sealing washer 5 imbeds arc caulking groove 4 more easily, and adopt the arc tank bottom to make the presetting of caulking groove 4 darker, sealing washer 5 installation is more firm, is difficult for droing.
Preferably, the cross-sectional width of the sealing ring 5 is greater than or equal to the pitch of the thread portion 2, and after the structure is adopted, as shown in fig. 2, when the thread portion 2 is in sealing connection with the working element, two sides of the sealing ring 5 are extruded and expanded by the thread teeth, so that the middle portion of the sealing ring 5 is arched outwards to be tightly attached to the thread, and the sealing ring 5 is completely filled in a pitch gap of the thread after being deformed, thereby achieving a better sealing effect.
Preferably, the seal ring 5 is made of nitrile rubber. By adopting the structure, the nitrile rubber is soft elastic rubber, and is easy to deform and expand when being extruded by the screw teeth, so that the screw teeth are fully filled, and the sealing effect is improved. And is more suitable for a small-sized water and gas transmission pipeline structure.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
