Abstract

The utility model discloses a cage type regulating valve. The cage type regulating valve comprises a valve body, a valve core, a valve rod and an upper valve cover, wherein a sealing device is arranged between the valve rod and the upper valve cover. The sealing device comprises a filler spring, a lower pad, filler, an upper pad, a U-shaped sealing ring and a filler pressing cover. A sealed filler containing groove is arranged in the upper valve cover, wherein the upper end of the sealed filler containing groove is provided with an opening. The valve rod penetrates into the sealed filler containing groove of the upper valve cover. The filler spring is sleeved on the valve rod, and the lower end of the filler spring is connected with the bottom surface of the sealed filler containing groove in an abutted mode. The upper end of the filler spring is connected with the lower pad in an abutted mode, the filler is arranged between the lower pad and the upper pad, and the upper pad is connected with the filler pressing cover in an abutted mode. The filler pressing cover is in screw joint with and is fixed with an opening of the sealed filler containing groove in the upper valve cover, and the U-shaped sealing ring is further arranged between the filler pressing cover and the valve rod. Therefore, compared with the fact that an existing regulating valve is sealed purely by relying on an O-shaped sealing ring, the sealing performance of the cage type regulating valve is greatly improved, and the whole service life of a valve is effectively prolonged.

Description

Cage type regulating valve
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of cage type regulating valve.
Background technique
Cage type regulating valve is a kind of in the valve, its structure mainly comprises valve body, spool, valve rod, bonnet, spool is installed in the valve body, bonnet is installed on the valve body, the spool that described valve rod passes in bonnet and the valve body is connected, but in the existing cage type regulating valve, usually only leans on the O RunddichtringO to seal between its valve rod and the bonnet, sealability is relatively poor, easily causes the valve whole service life to shorten.
Summary of the invention
For the deficiencies in the prior art, the utility model provides preferably cage type regulating valve of a kind of sealability.
For achieving the above object, the utility model provides a kind of cage type regulating valve, comprise valve body, spool, valve rod, bonnet, spool is installed in the valve body, bonnet is installed on the valve body, the spool that described valve rod passes in bonnet and the valve body is connected, be equiped with seal arrangement between described valve rod and the bonnet, described seal arrangement is by packing spring, lower liner, filler, upper liner, U-shaped seal ring, Gland consists of, offer the stuffing box packing containing groove of a upper end open on the bonnet, valve rod is arranged in the stuffing box packing containing groove of bonnet, described packing spring is set on the valve rod, and the lower end of packing spring and stuffing box packing containing groove bottom surface butt, the upper end of packing spring and lower liner butt, described filler are installed between lower liner and the upper liner, upper liner and Gland butt, the opening end of described Gland and bonnet upper gland packing containing groove is spirally connected fixing, and also is equiped with U-shaped seal ring between described Gland and the valve rod.
The beneficial effects of the utility model are: adopt said structure, because cage type regulating valve provided by the utility model, seal arrangement between its valve rod and the bonnet is to be made of packing spring, lower liner, filler, upper liner, U-shaped seal ring, Gland, therefore comparing the existing simple O RunddichtringO that leans on seals, its sealability is greatly enhanced, and has effectively prolonged the whole service life of valve.
The utility model can further be set to also be equiped with the O RunddichtringO between the stuffing box packing containing groove on described Gland and the bonnet, also be equiped with dirt-proof boot between described Gland and the valve rod, and described dirt-proof boot is flush-mounted on the upper-end surface of Gland.
Adopt said structure, the O RunddichtringO of setting up is the sealing effect of poppet further, and the dirt-proof boot of setting up can prevent from sneaking in the valve body dust when valve rod moves up and down.
The utility model also can further be set to be equiped with Support cushion between described packing spring and the lower liner, also is equiped with Support cushion between described Gland and the upper liner.
