Description
Technical field
The utility model belongs to valve technology field, and in particular to a kind of heat-preserving cut-off valve.
Background technology
At present, a kind of main application exactly liquefied gas at low temp such as liquid oxygen, liquid argon, liquid nitrogen and liquefied gas of stop valve
On warehousing and transportation facilities, such as in the storage equipment such as tank car, storage tank, opening and closing for control pressure container pipeline.It is existing
Stop valve mainly includes valve body, bonnet, valve top and valve rod, drives valve top to move up and down by valve rod, then realizes in valve body
The switch of flow of media passage and closing.Such stop valve is mainly the switch applied to cryogenic liquid, in order to reduce stop valve
Energy loss, it usually needs the valve body of stop valve or bonnet are designed as long neck structure, cold insulation is then wound on the outside of neck
Material, so as to reduce the energy loss of stop valve.Therefore, what the height of stop valve was typically designed is very high, causes stop valve to take
Space is big, installation inconvenience, while heat insulation effect is nor very well.
Utility model content
The purpose of this utility model is：For problems of the prior art, there is provided a kind of heat-preserving cut-off valve, it is maximum
The height of the reduction stop valve of degree, and good heat preservation performance.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of heat-preserving cut-off valve, including long-neck valve body, bonnet, valve top and long-neck valve rod, it is provided with long-neck valve body and is used for
The rod cavity of long-neck valve rod and the circulation passage for circulation medium are accommodated, described valve top, which is arranged in circulation passage, to be used for
Open or close circulation passage, valve top is connected with long-neck valve rod, and long-neck valve rod is placed in the rod cavity of long-neck valve body, long-neck valve body with
Bonnet is fixedly connected, and long-neck valve rod is threadedly coupled with bonnet；Heat-insulation material packed layer is provided with described rod cavity, is incubated
Extrusion spring is provided between one end of heat-insulating material packed layer and bonnet, the other end is matched somebody with somebody with the stage portion being arranged on the inside of valve body
Close.
Preferably, it is additionally provided with sealing gasket between the stage portion on the inside of described heat-insulation material packed layer and valve body
Sealing ring is also embedded with the inside of circle, with the heat-insulation material packed layer of long-neck valve stem contacts.
Preferably, described long-neck valve rod other end is provided with adjusting handle, is provided with the inside of top one end of bonnet
Filler and filler pressing sleeve, bonnet end set have the stuffing nut for being limited in filler pressing sleeve in bonnet, stuffing nut
It is connected with the outside screw of bonnet, and the clamp ring for locking stuffing nut is provided with the outside of bonnet.
By adopting the above-described technical solution, the beneficial effects of the utility model are：
Heat-preserving cut-off valve of the present utility model, filling is with guarantor made of heat-insulation material in the rod cavity of installation valve rod
Warm heat-insulating material packed layer, the energy for flowing through circulation passage medium is completely cut off by heat-insulation material packed layer, so as to
Effective control heat transfer, due to heat i.e. is initially formed into isolation from the bottom of heat-insulation material packed layer, so entirely
The height of heat-insulation material packed layer does not just have to design height that is too high, and then will farthest reducing stop valve.
