Description
【Technical field】
The utility model patent is related to valve field, and more particularly to a kind of valve is come off and stem wear with preventing guide sleeve
Bonnet guide frame.
【Background technology】
At present, existing guide sleeve is fixed on below bonnet mostly, is fixed by tolerance interference fit close-fitting, this structure
It is relatively simple, and after high-temperature medium hot-cool environment and long-term use, guide sleeve easily comes off, and filler and follower
Intermediate seal poor performance, failsafe valve can be caused, influence user's production safety.
【The content of the invention】
In view of the above-mentioned problems, led the utility model proposes, valve with the bonnet of stem wear with preventing that guide sleeve from coming off
To structure, including valve body and bonnet；Described bonnet is arranged on valve body, and described bonnet is provided with guide frame, described
Guide frame is that dual-guiding structure includes upper guide sleeve and lower guide sleeve；Described bonnet is provided with stuffing-box, the stuffing-box
In be provided with filler；Described lower guiding is set on the bottom of stuffing-box, and long gasket ring is provided with above the bottom of described stuffing-box,
Described upper guiding is set on above long gasket ring, and gland is provided with described bonnet, is gone back on described gland
Provided with O-ring seals.
The utility model, it is directed to set and is divided into two pieces up and down, lower guiding is placed on bonnet stuffing-box bottom, and above plus one grows
Gasket ring, long gasket ring top put guide sleeve, then put filler again, and an O-ring seals are added on gland.
The beneficial effect of the utility model structure：When regulating valve high-temperature medium hot-cool environment substitute, when long-term use of, no
Can be due to expanding with heat and contract with cold or external force causes guide sleeve to come off, dual-guiding structure and can makes valve rod remain good concentricity,
The filler not uneven wear caused by valve rod is offset is protected, so as to effectively improve the life that the service life of valve ensures user
Production safety.
【Brief description of the drawings】
Fig. 1 is structural representation of the present utility model；
Indicated in Fig. 1：Guide sleeve, 5- fillers, the long gasket rings of 6-, 7- fillers under 1- valve bodies, 2- bonnets, the upper guide sleeves of 3-, 4-
