Sealing gasket and joint composition, described joint is arranged on the lower end of connecting tube, and it is circle that the outside of described joint is fixed with cross section
The ring block of shape, the downside of described ring block is equipped with valve seal pad, and described valve seal pad is assembled together with valve body, institute
Stating the internally installed of joint and have valve rod, the axis of described valve rod and the axis of joint are on same straight line, described valve rod
Lower end be equipped with spool, be fixed by pin between described valve rod and spool.
Further, the upper part of described spool is that the centre position of cylindrical structural and spool upper part offers
Groove, the end portion of described spool is that upper surface is big, the truncated cone-shaped structure that lower surface is little.
Further, described spool uses elastomeric material to be made.
Further, described valve seal pad is the circulus that cross section is rectangle.
Further, it is attached by screw thread between described valve rod and spool.
The beneficial effects of the utility model: a kind of hard sealing structure angle pedestal valve of the present utility model, close by adding valve body
Packing achieves a butt joint the sealing between head and valve body, and this design effectively raises the sealing that this utility model is overall, solves
Traditional valve body of having determined is owing to sealing the problem of fluid leakage of the tightliest causing, and is fixed by pin between valve rod and spool, this
Design effectively raises the tightness between valve rod and valve body, additionally is easy to be replaced it after spool damages, and this sets
Meter is effectively reduced the cost changed needed for this utility model, and the design of spool then realizes fixing valve body, this design
Effectively raising the sealing that this utility model is overall, this utility model is easy to use, it is simple to operation, good stability, reliably

Accompanying drawing explanation
The detailed description with reference to the following drawings, non-limiting example made by reading, other spy of the present utility model
Levy, purpose and advantage will become more apparent upon:
Fig. 1 is the structural representation of this utility model a kind of hard sealing structure angle pedestal valve；
Fig. 2 is close-up schematic view at A in this utility model one hard sealing structure angle pedestal valve；
In figure: 1-valve body, 2-spool, 3-pin, 4-valve rod, 5-valve seal pad, 6-joint, 7-gas lid one, 8-gas lid
Two, 9-connecting tube.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below
In conjunction with detailed description of the invention, this utility model is expanded on further.
Referring to Fig. 1 and Fig. 2, a kind of technical scheme of this utility model offer: a kind of hard sealing structure angle pedestal valve, including main
Body structure and sealing structure, described agent structure is made up of gas lid 1, gas lid 28 and connecting tube 9, outside described gas lid 1
Shape is cylindrical barrel structure, and the lower end of described gas lid 1 is assembled together with gas lid 28, and described connecting tube 9 is cylindrical tube
Shape structure and connecting tube 9 run through gas lid 28 and are arranged.
Described sealing structure is made up of valve body 1, spool 2, pin 3, valve rod 4, valve seal pad 5 and joint 6, and joint 6 is pacified
Being contained in the lower end of connecting tube 9, the outside of joint 6 is fixed with the ring block of circular in cross-section, and the downside of ring block is equipped with valve
Body sealing gasket 5, achieves a butt joint the sealing between 6 and valve body 1 by adding valve seal pad 5, and this design effectively improves
