Description
Technical field
This utility model relates to a kind of valve type technical field, especially leakage-proof stop valve.
Background technology
Stop valve is the safety device of pressure piping, generally according to protection system on closed system equipment or pipeline
System safety, it is to set a nylon cushion between the connecting end surface of valve pocket and valve seat to seal that conventional stop valve seals, valve pocket and valve seat
Threaded fastening, nylon cushion is compressed, but, this sealing means can only make internal whorl even by the mode of axial seal
The liquid of the place's of connecing seepage does not leaks, and when the pressure height of pumped (conveying) medium, because nylon cushion material is the hardest, liquid can be along nylon
Padding slow seepage, the axial gasket between end face can not use rubber gasket to replace, although rubber gasket sealing
Higher, but packing material is the softest, rubber gasket can be squeezed deformation and cause leakage, do not reach close after two ends fastening pressurized
Envelope effect.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of leakage-proof stop valve, including
Handwheel, copper spool, copper valve pocket, groove, O, valve body, valve seat, valve pool, flap, set valve seat, set in described valve seat in described valve body
Valve pool, upper end sets copper valve pocket, sets copper spool in copper valve pocket, divides into external screw thread, and external screw thread is spirally connected with the female thread of described valve seat, on
End sets groove, sets O in groove, sets some O one and coordinate with the sealing of copper valve pocket in the middle of copper spool, and lower end sets flap, and upper end sets
Handwheel, flap is energy oscilaltion in valve pool, and this utility model sets groove in the junction of copper valve pocket Yu valve seat, sets O in groove,
The female thread of external screw thread and valve seat is spirally connected after fastening, and O the most all seals the junction of copper valve pocket with valve seat, greatly
Improve greatly the sealing property in a high voltage state of the liquid medium in stop valve.
For reaching above-mentioned purpose, the technical solution of the utility model is: leakage-proof stop valve, including handwheel, copper spool, copper
Valve pocket, groove, O, valve body, valve seat, valve pool, flap, set valve seat, set valve pool in described valve seat in described valve body, upper end sets copper
Valve pocket, sets copper spool in described copper valve pocket, divides into external screw thread, and described external screw thread is spirally connected with the female thread of described valve seat, and upper end sets
Groove, sets O in described groove, set some O one and coordinate with the sealing of copper valve pocket in the middle of described copper spool, and lower end sets flap, on
End sets handwheel, and described flap can oscilaltion in valve pool.
The beneficial effects of the utility model: this utility model sets groove in the junction of copper valve pocket Yu valve seat, set O type in groove
The female thread of circle, external screw thread and valve seat is spirally connected after fastening, and O is radially, axially two sides, junction of copper valve pocket Yu valve seat
To sealing, and O is quality of rubber materials, and after the pressurized that is screwed, the sealing area of groove adjusts shape seal perimeter automatically again,
Substantially increase the sealing property in a high voltage state of the liquid medium in stop valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the left view of Fig. 1.
In figure: handwheel 1, copper spool 2, O 1, copper valve pocket 3, groove 301, external screw thread 302, O 4, valve body 5, valve

Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Fig. 1～Fig. 2, leakage-proof stop valve, including handwheel 1, copper spool 2, copper valve pocket 3, groove 301, O 4, valve
Body 5, valve seat 6, valve pool 601, flap 7, set valve seat 6, set valve pool 601 in described valve seat 6 in described valve body 5, upper end sets copper valve pocket
3, set copper spool 2 in described copper valve pocket 3, divide into external screw thread 302, described external screw thread 302 is spirally connected with the female thread of described valve seat 6,
Upper end sets groove 301, sets O 4 in described groove 301, and described copper spool 2 centre sets some O 1 and seals with copper valve pocket 3
Coordinating, lower end sets flap 7, and upper end sets handwheel 1, and described flap 7 is energy oscilaltion in valve pool 601, and this utility model is at copper valve
Set 3 sets groove 301 with the junction of valve seat 6, sets O 4 in groove 301, and the female thread of external screw thread 302 and valve seat is spirally connected after fastening, O
4 copper valve pockets of type circle 3 seal with the junction radially, axially both direction of valve seat 6, and O 4 is quality of rubber materials, screw thread
After fixing pressurized, the sealing area of groove 301 adjusts shape seal perimeter automatically again, substantially increases the liquid medium in stop valve
Sealing property in a high voltage state.
Of the present utility model ultimate principle and principal character, and of the present utility model advantage have more than been shown and described.
The technical staff of the industry is also aware that, this utility model is not limited by above-mentioned case study on implementation, above-mentioned case study on implementation and description
