Abstract
The utility model provides an adjustable quick coupling, which ensures the sealing degree and no rupture or escaping in the using process. The adjustable quick coupling comprises a handwheel connected to a valve rod. The utility model is characterized in that the valve rod is disposed in the valve body; at least one embedding groove is arranged on the inner wall of the valve body; a sealing ring is disposed in the embedding groove and sleeves the surface of the valve rod. By adopting the embedding groove structure, the utility model is advantageous in that the sealing ring will not escape and is not easy to break; the sealing ring is fixed, safe and reliable; the service life of the sealing ring is prolonged.
Description
Technical field
The utility model relates to a kind of pipeline connection device equipment, relates in particular to a kind of adjustable rapid pipe joint.
Background technique
The structure of air-conditioning becomes increasingly complex in the prior art, and especially air-conditioning duct is intricate.Pipeline is connected with pipeline for convenience, and dismounting fast, adopts adjustable rapid pipe joint in the prior art usually.Pipe ends is coupled together, without mantle fiber, convenient and swift.Rapid pipe joint of the prior art has straight-through type/structures such as list sealing/double-enclosure.Be suitable for various situations.But adjustable rapid pipe joint of the prior art as shown in Figure 1, adopts embedded seal ring 6 structures, comprises the handwheel 1 of being with valve rod 5, and handwheel 1 is connected to valve body 2, has been provided with the interior cover 3 of piston seal effect in the valve body 2, and valve body 2 outsides are provided with the overcoat 4 that connects usefulness.In order to seal; have embedding groove 7 on the valve rod 5; with embedding groove 7 on be with seal ring 6; though such structure is easy to process; but in use because valve rod 5 moves, therefore through regular meeting the situation that seal ring 6 slides up and down takes place, even the phenomenon that seal ring 6 is overflowed can take place; cause freezing medium leakage, the entail dangers to operator are healthy.
The model utility content
The purpose of this utility model provides a kind of adjustable rapid pipe joint, and the user can guarantee seal degree in use, and seal ring can not break or overflow.
In order to reach described effect, a kind of adjustable rapid pipe joint of the utility model comprises the handwheel that is connected on the valve rod, described valve rod is arranged in the valve body, have at least one embedding groove on the described valve interior wall, in the described embedding groove seal ring is installed, seal ring is locked in stem surface.
Preferably, described embedding groove quantity is 2.Even have the situation of the seal ring generation fracture in the embedding groove also can not cause the leakage of whole valve body like this, guaranteed the seal in the valve body.
Preferably, described two embedding grooves be arranged in parallel, and width is identical, and distance is greater than the embedding groove width between two embedding grooves.Such structure makes the utilization efficiency of seal ring be improved under the prerequisite that guarantees sealing effect.
Preferably, valve rod and handwheel pass through bolt.Such means of fixation is simple and reliable.
Preferably, be stamped the bolt cover plate outside the described bolt.Make the total outward appearance more attractive in appearance.
Owing to adopted described technological scheme, the utility model adopts the embedding groove structure, so seal ring can not overflow, and has also reduced the possibility that seal ring breaks simultaneously.And the fixed-site of seal ring is motionless, and is safe and reliable, prolonged the working life of seal ring.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the schematic representation of rapid pipe joint in the prior art.
Fig. 2 is the schematic representation of a kind of adjustable rapid pipe joint of the utility model.
Embodiment
As shown in Figure 2, a kind of adjustable rapid pipe joint of the utility model, comprise the handwheel 1 that is connected on the valve rod 5, described valve rod 5 is arranged in the valve body 2, it is characterized in that: have at least one embedding groove 7 on described valve body 2 inwalls, in the described embedding groove 7 seal ring 6 is installed, seal ring 6 is locked on valve rod 5 surfaces.Described embedding groove 7 quantity are 2.Described two embedding grooves 7 be arranged in parallel, and width is identical, and distance is greater than embedding groove 7 width between two embedding grooves 7.Such structure makes the utilization efficiency of seal ring 6 be improved under the prerequisite that guarantees sealing.Valve rod 5 and handwheel 1 are fixing by bolt 8.Bolt cover plate 9 is stamped in described bolt 8 outsides.Make the total outward appearance more attractive in appearance.
Embedding groove 7 just gives moulding when valve body 2 die sinkings, the seal ring 6 of packing into when assembling.By such structure, adjusting handle 1 makes sealing between the seal ring 6 and valve rod 5 when valve rod 5 motion.And seal ring 6 can not move along with the motion of valve rod 5, reduced the possibility that seal ring 6 is overflowed.Safe and reliable, improved sealability, prolonged the working life of seal ring.
The above only is a specific embodiment of the present utility model, but technical characteristics of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the scope of the present utility model.
