Abstract
The utility model discloses a kind of joint, comprise joint body, described joint body comprises the first connecting end, the second connecting end and is arranged on the limited part on the joint body between the first connecting end and the second connecting end; Described first connecting end screws togather with connecting head and is connected, described connecting head offers connection mouth away from one end of the first connecting end, the connecting head of described connection mouth surrounding is provided with supporting walls, the inwall of described connecting head is also provided with the fixing part of annular, described fixing part is provided with seal ring, and described seal ring and supporting walls compress with the first connecting end and are connected.A kind of joint of the present utility model, makes seal ring generation deformation by the pressure of joint inside, the seal ring after deformation and pipe fitting tight clamping fit, being tightly connected of the pipe fitting completed; First fluid passage and the second fluid passage connecting place of inside pipe fitting offer diversion division, make internal diameter smooth change, can not produce resistance and noise.
Description
technical field:
The utility model relates to a kind of joint.
background technique:
Pipe joint is connecting element necessary when being connected between pipe fitting with pipe fitting.Existing joint adopts the mode be threaded mostly, but this Placement must hold screw thread successfully in advance on the connecting end of pipe fitting, just cannot use in the occasion much cannot opening screw thread.And also there is very large deficiency in the existing connection being connected to different inner diameters pipe fitting, the pipe fitting of different inner diameters easily causes great fluid resistance in intersection, affects the laser propagation effect of fluid.
summary of the invention:
The purpose of this utility model is to solve the problems of the prior art, provides one not need screw thread also can connect, and good sealing effect, and the joint of different inner diameters smooth conversion can be carried out in inside.
In order to achieve the above object, the technical solution of the utility model is:
A kind of joint, comprise joint body, described joint body comprises the first connecting end, the second connecting end and is arranged on the limited part on the joint body between the first connecting end and the second connecting end; Described first connecting end screws togather with connecting head and is connected, described connecting head offers connection mouth away from one end of the first connecting end, the connecting head of described connection mouth surrounding is provided with supporting walls, the inwall of described connecting head is also provided with the fixing part of annular, described fixing part is provided with seal ring, and described seal ring and supporting walls compress with the first connecting end and are connected.
Described first connecting end inside offers first fluid passage, and described second connecting end inside offers second fluid passage, and the internal diameter of described first fluid passage is less than the internal diameter of second fluid passage.
Described first fluid passage is connected with second fluid passage, and described first fluid passage and second fluid passage connecting place offer diversion division.
Described fixing part is connected with supporting walls, and described fixing part offers arc groove.
The internal diameter of described connection mouth is identical with the internal diameter of seal ring.
The beneficial effects of the utility model are: a kind of joint of the present utility model, make seal ring generation deformation by the pressure of joint inside, the seal ring after deformation and pipe fitting tight clamping fit, being tightly connected of the pipe fitting completed; First fluid passage and the second fluid passage connecting place of inside pipe fitting offer diversion division, make internal diameter smooth change, can not produce resistance and noise.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
Embodiment 1
A kind of joint as shown in Figure 1, comprises joint body 1, and described joint body 1 comprises the first connecting end 2, second connecting end 3 and is arranged on the limited part 4 on the joint body 1 between the first connecting end 2 and the second connecting end 3.Described first connecting end 2 screws togather with connecting head 5 and is connected, described connecting head 5 offers connection mouth 51 away from one end of the first connecting end 2, the connecting head 5 of described connection mouth 51 surrounding is provided with supporting walls 52, the inwall of described connecting head 5 is also provided with the fixing part 53 of annular, described fixing part 53 is provided with seal ring 6, and described seal ring 6 and supporting walls 52 compress with the first connecting end 2 and are connected.
Described first connecting end 2 inside offers first fluid passage 21, and described second connecting end 3 inside offers second fluid passage 31, and the internal diameter of described first fluid passage 21 is less than the internal diameter of second fluid passage 31.Described first fluid passage 21 is connected with second fluid passage 31, and described first fluid passage 21 and second fluid passage 31 connecting place offer diversion division 7.First fluid passage 21 is different from the internal diameter of second fluid passage 31, is completed the connection of different inner diameters pipe fitting by joint, and diversion division 7 completes the smooth transition between different inner diameters passage, the noise reducing flow resistance and send.
Described fixing part 53 is connected with supporting walls 52, and described fixing part 53 offers arc groove 8.The internal diameter of described connection mouth 51 is identical with the internal diameter of seal ring 6.Pipe fitting being inserted into after in connection mouth 51 and seal ring 6, being rotationally connected 5 and supporting walls 52 and the first connecting end 2 pairs of seal rings 6 is extruded, be that seal ring 6, according to the arc groove 8 on fixing part 53, deformation occurs, carry out clamping to pipe fitting, simple and convenient.
A kind of joint of the present embodiment, makes seal ring generation deformation by the pressure of joint inside, the seal ring after deformation and pipe fitting tight clamping fit, being tightly connected of the pipe fitting completed; First fluid passage and the second fluid passage connecting place of inside pipe fitting offer diversion division, make internal diameter smooth change, can not produce resistance and noise.
