The matched binding groove 201 of firmware 302.
Further, the fastener 302 is connected through a screw thread with the binding groove 201, and on the fastener 302
Reach is greater than the reach in binding groove 201.
Specific embodiment：The present apparatus is high pressure sealing joint, mainly plays the role of connection and sealing, present apparatus master
It to include the first connector 100 and the second connector 200, wherein the first connector 100 can be steel pipe, the second connector 200
Can be threeway, two is logical or plug etc., by the way that the first connector 100 and the second connector 200 are docked, realize in connection,
Connect again with the first connector 100 and the second connector 200 respectively by joint assembly 300, to realize outer fixation, by the
A connection piece 100 is docked with the second connector 200, is kept its first connector 100 good with the second connection sealing, is passed through connector group
It is more stable that part 300 connect its first connector 100 with the second connector 200, and present apparatus installation operation is simple, sealing performance
It is good.
During connecting inside, the second end 210 of first end and the second connection to the first connector 100 is done
Further improvement, specific improved place are first conical surface 111 and second conical surface 112 to be arranged in first end, such as Fig. 1
Shown in 2, the formation of first conical surface 111 and second conical surface 112 can be to be realized by simple tool, for example, screw die or
Manual inner chamfer machine.
The generally spherical structure of the second end 210 of second connector 200, as indicated in figs. 1 and 3, therefore can be by
Two ends 210 screw in the seal chamber formed to first conical surface 111 and second conical surface 112, and then 100 He of the first connector made
Second connector, 200 better tightness.
In the connection procedure of existing first connector 100 and the second connector 200, the connection type of use would generally be selected
The mode of welding or non-solder, welding manner is complicated, and requires to operator and equipment very high, and cannot reproduce
The difficulty of construction of field operation, scene effect is especially big；And the mode of non-solder is usually cutting ferrule connection or outer bevel sealing surface
With the linear sealing mode of connector, the linear sealing mode of especially outer bevel sealing surface and connector again requires extremely installation accuracy
Height does not allow especially the first connector 100 occur to there is a situation where skew, and then makes to connect work difficulty increase, working efficiency
It is lower, by the discovery that studies for a long period of time of researcher, by using the connection type of this structure, by the of the second connector 200
Two ends 210 are screwed in seal chamber, are in certain arc outside the second end 210, therefore during installation, even if the first connection
There are slight skews for part 100, can still guarantee the leakproofness of the first connector 100 and the second connector 200.
Existing first connector 100 and the connection type of the second connector 200 there is also the mode that thread seal connects,
There is also certain problems to be for the connection type, and the first connector 100 or the second connector 200 exist cannot be random around axis
The problem of rotating and some specified position can only be rested on, and the connection type of use this structure, 100 He of the first connector
Second connector 200 can rotate about the axis, and can rest on arbitrarily position, to reduce the difficulty of operation.
In the present embodiment, the second end 210 can be screwed in seal chamber, main function be first conical surface 111 with
Angle between second conical surface 112, the optional range of the angle are 60~120 °, the second end 210 can be made to revolve less than this range
Enter difficulty increase, the leakproofness between the second end 210 and seal chamber can be made bad again greater than this range, therefore passes through research people
Member's is continually striving to the study found that range is selected as 60~120 ° most preferably, and can be connected according to specific first connector 100 and second
Fitting 200 does the adjustment of adaptability.
In the present embodiment, the angle between first conical surface 111 and second conical surface 112 is more preferably 90 °, and the angle is not
It only can satisfy easy for installation, moreover it is possible to meet good airproof performance, more can be realized first conical surface 111 of processing and second conical surface 112
It is convenient, so that working efficiency greatly improves.
The outer of high pressure sealing joint is connected and fixed, and is mainly connected by joint assembly 300 and the first connector 100 and second
Fitting 200 connects and connect by snap ring 400 with the first connector 100 realization, and joint assembly 300 mainly includes connector master
Body 301 and fastener 302, adapter body 301 is cylindrical, as shown in figs. 1 and 4, wherein one end of adapter body 301 and the
A connection piece 100 connects, and fastener 302 is arranged in the inner wall of the other end of adapter body 301, by fastener 302 come with second
Connector 200 connects.Fastener 302 and adapter body 301 are integrally formed, and are conducive to make the first connector 100 and second in this way
Connector 200 consolidates, and in the present embodiment, and the connection type of optional fastener 302 and the second connector 200 is screw thread
Connection, and the screw thread of embedded division 402 and the annular groove 101 is left hand thread, and the benefit being arranged in this way is 402 He of embedded division
Connection between annular groove 101 is not easy to loosen.
Snap ring 400 is connect with the first connector 100, and snap ring 400 mainly includes integrally formed ring body 401 and insertion
Portion 402 as described in figures 1 and 5, and is arranged the annular groove 101 to match with embedded division 402 on the first connector 100, will be embedded in
Portion 402 is placed in annular groove 101, by setting taper for the longitudinal section of embedded division 402, and processes spiral shell on embedded division 402
Line is threadedly coupled by screw thread with annular groove 101, so that snap ring 400 and the connection of annular groove 101 are stronger, ring sheet
The main function of body 401 is support joint main body 301, makes the first connector 100 during the installation process and fixation procedure
In, the first connector 100 will not be fallen easily, so that the firm performance of whole device is stronger.
In the present embodiment, the reach in optional annular groove 101 is greater than the reach of embedded division 402, passes through research
Personnel's the study found that when the rotation of the second end 210 of the second connector 200 such as in seal chamber when, 100 possibility of the first connector
Flexible deformation can occur, and then make its first connector 100 that slight skew occur, by setting the reach in annular groove 101
The reach greater than embedded division 402 is set, when slight skew occurs, by adjusting the first connector 100, so as to guarantee
Leakproofness between first connector 100 and the second connector 200, so that sealing effect is unaffected.
Outside during fixed connection type, the reach in optional fastener 302 is greater than outside the second connector 200
The reach of wall, during the installation process, the second connector 200 and joint assembly 300 can play key tune to firm
The effect of section.
The installation process of the present embodiment：
The first step：It will be first socketed on the first connector 100 outside joint assembly 300：
Second step：Snap ring 400 is screwed in the first connector 100 again；
Third step：The first connector 100 is docked with the second connector 200 again；
4th step：By rotary joint assembly 300, make joint assembly 300 and the first connector 100 and the second connector
200 are threadedly coupled.
Present apparatus structure is simple, and installation and processing are simple, while can not only meet the first connector 100 and the after installing
The sealing element of two connectors 200 also can guarantee the stability of the first connector 100 and the second connector 200.
Although an embodiment of the present invention has been shown and described, it will be understood by those skilled in the art that being：?
