Fig. 1-3 is please referred to, the utility model provides a kind of technical solution:
A kind of cutting ferrule ball valve offers mounting hole 13 in valve body 1 as shown in Figure 1, Figure 2 and Figure 3, including valve body 1, installs
Spool 2 is installed in hole 13, mounting head 11 is equipped at the left and right ends of valve body 1.
Specifically, the side endface of mounting head 11 offers spring eye 111, spring eye 111 is successively socketed from inside to outside
There are spring 112 and withstanding tight block 113.
Further, the outside of mounting head 11 is shape of threads, and the outside screw of mounting head 11 is connected with cutting ferrule nut 12, is blocked
Threaded hole bottom end on set nut 12 offers the aperture 121 for pipe laying, and the threaded hole bottom end on cutting ferrule nut 12 is set
Have a support block 122, the left side of support block 122 is equipped with inner edge 123, when pipeline from.
In addition, withstanding tight block 113, support block 122 and inner edge 123 are annular shape, ring heart part is used to be socketed pipeline, hold out against
113 inner wall of block offers retaining ring close to the side of spring 112, and when pipeline is inserted into from aperture 121, the top of pipeline is held out against
Retaining ring on block 113 resists, while so that support block 122 is resisted 123 inside of inner edge by screwing cutting ferrule nut 12, withstanding tight block 113
The outside of inner edge 123 is resisted under the elastic reaction of spring 112, the side wall of the inner end incision pipeline of inner edge 123 reaches company at this time
The effect in adapter tube road.
Specifically, mounting hole 13 is the counterbore opened up vertically, the aperture of mounting hole 13 is threaded with top cover 14, passes through top
Threaded connection of the lid 14 in mounting hole 13 makes to screw top cover 14 for sealing element 16 and spool 2 is fixed.
Further, the bottom hole installation of mounting hole 13 is there are two symmetrical sealing element 16, the top of sealing element 16 with
It is equipped with gasket 15 between the bottom end of top cover 14, sealing element 16 and gasket 15 use heat-resisting, cold-resistant, oil resistant and ageing-resistant
The silastic material of superior performance is made.
Specifically, spool 2 is socketed between two sealing elements 16, outer surface and the sealing element 16 of spool 2 are fitted closely, valve
The middle part of core 2 offers through-hole 21, and the top of spool 2 is fixed with valve rod 22, and the bottom end of spool 2 is fixed with shaft 23, shaft 23
It is plugged on the bottom hole of mounting hole 13.
The bottom end of valve rod 22 and spool 2 closely weld, and the top of valve rod 22 is shape of threads, and top cover is run through on the top of valve rod 22
14 and it is socketed with handle 221, handle 221 is fixed on the top of valve rod 22, the bottom of shaft 23 and spool 2 by fixture nut 312
The close welding in end, makes rotation handle 221, and handle 221 is rotated with ovable valve stem 22 and 23 sealed around the shaft at two with movable valve plug 2
It is rotated between part 16.
It is worth noting that the through-hole of connection 1 left and right ends of valve body is laterally offered in valve body 1, when the rotation of spool 2 makes valve
When the through-hole on through-hole 21 and valve body 1 on core 2 is in the same direction, the left and right ends of valve body 1 are in connected state, when the rotation of spool 2 makes
When through-hole 21 on spool 2 is vertical with the through-hole on valve body 1, the left and right ends of valve body 1 are in an off state.
The cutting ferrule ball valve of the present embodiment when in use, by the mounting hole 13 being arranged in valve body 1, and in mounting hole 13
