And lose sealing effectiveness.To this end, be presently required, this joint is improved, with satisfied use needs.
Utility model content
Based on this, for the problems referred to above, it is necessary to propose a kind of high pressure sealing joint, this high pressure sealing joint
Rubber ring in prior art is overcome to be easily damaged, so that joint loses the shortcoming of sealing effectiveness, and structure letter
Single, easy for installation, low price.
The technical solution of the utility model is: a kind of high pressure sealing joint, including female joint, copper packing, pressure head
And locking nut, female joint one end is provided with the cylindrical recesses for installing locking nut, pressure head and copper packing, copper
The center of pad offers the first delivery hole, and pressure head includes that platen and one end are perpendicularly fixed at this platen center
Guide pillar, the center of this platen and the center of guide pillar are provided with the second through delivery hole, in locking nut
Have at the heart and be available for the guide pillar through hole that guide pillar passes, in cylindrical recesses, be provided with the thread head phase with locking nut
The screw thread joined, copper packing is placed in bottom cylindrical recesses, and platen is placed on copper packing, and locking nut knob is recessed in column
In groove, guide pillar is made to pass its guide pillar through hole, being connected with one end of connecting pipe away from one end of platen of guide pillar,
The liquid-conveying ducts of the liquid-conveying ducts of female joint, the first delivery hole, the second delivery hole and connecting pipe is sequentially communicated.
Preferably, guide pillar is fastened by welded seal with the junction of connecting pipe.
The beneficial effects of the utility model are:
(1) overall structure is the simplest so that install, safeguard more convenient, its cost of manufacture and maintenance cost
Cheap；
(2) compared with the prior art, do not use seal with elastometic washer, but use the mode of welding by connecting pipe
Sealing with pressure head, locking nut makes pressure head and copper packing closely cooperate the effect reaching to seal after tightening in female joint
Really so that overall structure sealing effectiveness is more preferable, and anti-pressure ability is higher.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described in detail.
Embodiment:
As shown in Figure 1, Figure 2, shown in Fig. 3 or Fig. 4, a kind of high pressure sealing joint, including female joint 100, copper
Pad 200, pressure head 300 and locking nut 400, female joint 100 one end be provided with for install locking nut 400,
The cylindrical recesses 101 of pressure head 300 and copper packing 200, the center of copper packing 200 offers the first delivery hole 201,
Pressure head 300 includes that platen 301 and one end are perpendicularly fixed at the guide pillar 302 of this platen center, this platen 301
Center and the center of guide pillar 302 be provided with the second through delivery hole 303, the center of locking nut 400
Place has and is available for the guide pillar through hole 401 that guide pillar 302 passes, and is provided with and locking nut 400 in cylindrical recesses 101
The screw thread 102 that matches of thread head, copper packing 200 is placed in bottom cylindrical recesses 101, and platen 301 is placed in copper
On pad 200, locking nut 400 knob, in cylindrical recesses 101, makes guide pillar 302 through its guide pillar through hole
401, being connected with one end of connecting pipe 500 away from one end of platen of guide pillar 302, the drain of female joint 100
