Water grooving is respectively communicated with inlet opening upper end and apopore upper end, and there are two cut respectively with water inlet grooving and water outlet for installation on gland
The pipe fitting that slot is connected.
Casing is equipped in gap between the thinner one end of stepped hole and valve shaft, described sleeve pipe housing is outside valve shaft, in casing
It is externally provided with spiral shape grooving, a spirality channel is enclosed by spiral shape grooving and stepped hole inner wall, inlet opening lower end and is gone out
Water hole lower end is respectively communicated with the upper and lower ends of spirality channel.
Carbon seal ring is equipped in the gland of two sides above and below water inlet grooving and water outlet grooving.
Carbon seal ring is equipped between valve shaft lower end and stepped hole.
The technical effect of the utility model are as follows: in use, after cooling water is entered by gland water inlet grooving, successively by water inlet
After hole, gap and apopore, from gland water outlet grooving discharge, valve shaft and axle sleeve are carried out using the cooling water of circulation effectively quick
Cooling, the generation heat transfer after preventing the high-temperature medium of spool contact is to actuator, and apparatus structure is simple, manufacture and dimension
It repairs conveniently.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing:
Fig. 1 is the schematic diagram of the section structure of the utility model,
Fig. 2 is schematic perspective view of the utility model about casing and valve shaft.
In figure: axle sleeve 1, valve shaft 2, gland 3, actuator 4, pipe fitting 5, filler 6, gasket 7, casing 8, carbon seal ring 9,
Stepped hole 11, inlet opening 21, apopore 22, water inlet grooving 31, water outlet grooving 32, spiral shape grooving 81.
Specific embodiment
As illustrated in fig. 1 and 2, a kind of valve shaft cooling device, including valve shaft 2 and axle sleeve 1 are equipped with stepped hole 11 in axle sleeve 1,
Valve shaft 2 is arranged in stepped hole 11, and gasket 7 and filler 6 are equipped in the thicker one end of stepped hole 11, is installed on axle sleeve 1 useful
There is gap between the gland 3 being pressed on filler 6 on gasket 7, the thinner one end of stepped hole 11 and valve shaft 2, opened in valve shaft 2
Equipped with inlet opening 21 and apopore 22,21 lower end of inlet opening and 22 lower end of apopore are respectively communicated with the upper and lower ends in gap；It is pressing
Be equipped with water inlet grooving 31 and water outlet grooving 32 in lid 3, water inlet grooving 31 and water outlet grooving 32 be respectively communicated with 21 upper end of inlet opening and
22 upper end of apopore is installed on gland 3 there are two the pipe fitting 5 being connected respectively with water inlet grooving 31 and water outlet grooving 32,
2 upper end of valve shaft is connect by female connector with actuator, is rotated in axle sleeve 1 by actuator driven valve shaft 2.
The course of work and working principle of the utility model are as follows: cooling water is passed into water grooving 31 by pipe fitting 5
Afterwards, successively after inlet opening 21, gap and apopore 22, the pipe fitting 5 being connected to water outlet grooving 32 is discharged cooling water, with
Cooling constantly pours into, and forms recirculated cooling water, takes away 2 heat of valve shaft using recirculated cooling water, effectively cold to carry out to valve shaft 2
But, the generation heat transfer after the high-temperature medium for preventing spool from contacting in cooling water carries out valve shaft 2 cold to actuator 4
When but, the normal rotation of valve shaft 2 is not influenced, and cooling water pipeline, which will not be beaten, to be kinked around cooling device structure is simple, maintenance and manufacture
