Abstract
The utility model discloses a high-temperature high-pressure corrugated-pipe adjusting valve. A lower valve deck is connected with a valve body through a screw and fixes a sleeve and a valve seat in a valve cavity in a tightly pressing mode, heat-dissipating fins are arranged outside a high-temperature connecting pipe, the lower end of the high-temperature connecting pipe is connected with the lower valve deck in a welded mode, the upper end of the high-temperature connecting pipe is connected with a connecting pipe flange in a welded mode, and the connecting pipe flange is connected with an upper valve deck through screws. A corrugated pipe disc is arranged between the connecting pipe flange and the upper valve deck and is pressed tightly and fixed through the upper valve deck, a corrugated pipe is arranged in an inner cavity of the high-temperature connecting pipe, the upper end of the corrugated pipe is connected with the corrugated pipe disc in a welded mode, and the lower end of the corrugated pipe is closely attached to the upper end face of a lower valve rod due to the elastic deformation of the corrugated pipe. A valve core is movably arranged in an inner hole of the sleeve and connected with the lower valve rod, the lower valve rod penetrates through the upper end face of the lower valve deck and is fixedly connected with an upper valve rod, the upper valve rod upwardly penetrates through the corrugated pipe, the corrugated pipe disc and the upper valve deck, and a stuffing box is arranged between the upper valve rod and the upper valve deck for sealing. According to the high-temperature high-pressure corrugated-pipe adjusting valve, a dual sealing method through the corrugated pipe and the stuffing box is utilized so that the sealing performance is good, and the high-temperature high-pressure corrugated-pipe adjusting valve can meet requirements of toxic, flammable, high-temperature and high-pressure working occasions.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of High Temperature High Pressure bellows regulating valve.
Background technique
Because valve runs into poisonous inflammable gas when work, depend merely on stuffing box and prevent that medium from leaking outside is inadequate, at this moment just need bellows to stop medium to leak outside, the double seal of bellows and stuffing box has guaranteed sealing, but when running into the High Temperature High Pressure occasion, general bellows regulating valve can not meet the demands.
Summary of the invention
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of employing bellows and stuffing box double seal, and good airproof performance can satisfy the High Temperature High Pressure bellows regulating valve of poisonous inflammable, High Temperature High Pressure workplace.
The utility model is implemented by the following technical programs:
The High Temperature High Pressure bellows regulating valve, it is characterized in that: comprise valve body, valve seat, spool, sleeve, bonnet, bottom flange, upper valve rod, lower valve rod, high temperature is taken over, bellows and bellows dish, bottom flange and valve body are connected by screw, bottom flange is pressed abd fixed on sleeve and valve seat in the valve pocket, high temperature is taken over the peripheral hardware radiating fin, high temperature is taken over the lower end and bottom flange is welded to connect, the upper end is welded to connect with pipe connecting flange, pipe connecting flange and bonnet are connected by screw, the bellows dish is located between pipe connecting flange and the bonnet and is fixed by bonnet, bellows is located at the inner chamber that high temperature is taken over, the bellows upper end is welded to connect with the bellows dish, the bellows lower end fits tightly by the resiliently deformable of bellows and the upper-end surface of lower valve rod, the endoporus that sleeve is located in the spool activity is connected with lower valve rod, the upper-end surface that lower valve rod passes bottom flange is fixedly connected with upper valve rod, and upper valve rod is upward through bellows, bellows dish and bonnet are provided with packing box seal between upper valve rod and the bonnet.Bellows adopts the alloy material.
In technique scheme, when high-temperature high-pressure medium arrives high temperature adapter inside gradually by body cavity, so at this moment owing to fit tightly the possibility that has effectively stoped high-temperature high-pressure medium to flow out from here between bellows lower end and the lower valve rod upper-end surface, when medium arrives the bellows upper end, because closely weld with the bellows dish bellows upper end, so medium also is to flow out from this, the good airproof performance of bellows; Bellows is owing to adopt the specific alloy material to make simultaneously, maximum pressure can reach 42Mpa, and maximum temperature can arrive 700 degrees centigrade, so can well overcome high-temperature high-pressure medium to its destruction, guarantee the safety of producing, can be widely used in the workplace of some poisonous inflammable High Temperature High Pressure.
As preferably, sleeve is comprised of upper bush and lower sleeve, adopts the sealing of metal C type circle between spool and the sleeve, and metal C type circle is located in the annular seal groove, and annular seal groove forms between the upper-end surface of the lower end surface of upper bush and lower sleeve.Metal C type circle expands to realize sealing by pressure medium and self elastic force, and the highest bearing temperature can reach 700 degrees centigrade, can effectively solve the problem of temperature high pressure disaster sealing.
