Description
Technical field
The present invention relates to a kind of valve, particularly a kind of pressure balance type regulating valve of the high-temperature pipe be applicable in the fields such as chemical industry, oil, electric power.
Background technique
In prior art, there is a kind of high-temperature valve, its structure comprises the valve body of hollow, valve body lower end is provided with import, valve body side is provided with outlet, valve body upper end is sealedly connected with valve gap, and between valve gap and valve body, in warp, flange is connected with gasket seal, and valve rod extend in valve body through valve gap, valve rod lower end is provided with flap, be provided with the valve seat corresponding with flap in described valve body, valve seat and valve body manufacture, after flap falls into valve seat, be cut off between import (individual) and outlet, after flap departs from valve seat, be switched between import and outlet, fluid is passed through; Be provided with stuffing box packing between valve gap and valve rod, valve rod be set with the gland for press seal filler, described gland is connected through adjusting screw with valve gap, and valve rod upper end is provided with operating-controlling mechanism.This valve is one of visual plant of coal chemical engineering equipment system, is arranged on the emptying pipeline of high temperature hot-blast furnace, and as a kind of special special valve of discharging unnecessary high-temperature hot-air directly to air, and the position of installing is also very high.The temperature of hot blast is between 1000 DEG C ~ 1200 DEG C, and working pressure is at 2.5MPa.Valve is in unlatching temperature greatly about about 1000 DEG C, and high temperature gas medium passes through valve very soon under the pressure of 2.5MPa.For the normal operation of assurance device, require that this valve is high temperature resistant, sealing is reliable, long service life.
Exist owing to often having high-temperature pipe in the fields such as chemical industry, oil, electric power; regulate the regulating valve of the pressure common form of these high-temperature pipes often cause the high temperature deformation of valve rod and cause valve to work, how to keep the normal morphology of high temperature lower valve rod to work in order to valve normal and to be eager the difficult problem that solves into valve manufacture enterprise.
Summary of the invention
The object of this part is some aspects of general introduction embodiments of the invention and briefly introduces some preferred embodiments.May do in the specification digest and denomination of invention of this part and the application a little simplify or omit with avoid making this part, specification digest and denomination of invention object fuzzy, and this simplification or omit and can not be used for limiting the scope of the invention.
In view of Problems existing in above-mentioned and/or existing high temperature modification pressure balance type modulating valve and method for cleaning, propose the present invention.
Therefore, an object of the present invention is to provide a kind of high temperature modification pressure balance type modulating valve, it can make valve stem keep normal working morphology at high operating temperatures.
For solving the problems of the technologies described above, the invention provides following technological scheme: a kind of high temperature modification pressure balance type modulating valve, comprise valve body, sleeve, valve plug, valve gap, valve stem, filler and actuator, described sleeve is arranged on valve body, described valve plug to be arranged in sleeve and can to make Relative sliding, described valve stem upper end is connected with actuator through the through hole of valve gap central authorities and there is packing seal centre, lower end connects valve plug, described valve gap has radiating structure, described radiating structure and valve gap join together, valve stem and valve gap transmission of heat by contact, valve gap carries splintery radiating structure, its radiating structure is vertical with valve stem and/or parallel fashion.
The present invention efficiently solves the yielding problem of pressure regulator valve family of power and influence bar of high-temperature pipe when increasing little cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme of the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.Wherein:
Fig. 1 is the structural representation of a kind of high temperature modification pressure balance type modulating valve of the present invention.
Fig. 2 is the structural representation of a kind of high temperature modification pressure balance type modulating valve of the present invention
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with specific embodiment.
Set forth a lot of detail in the following description so that fully understand the present invention, but the present invention can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention, therefore the present invention is by the restriction of following public specific embodiment.
Secondly, alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the present invention.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
In figure, 1, valve body; 2, sleeve; 3, valve plug; 4, valve gap; 5, valve stem; 6, filler; 7, radiating structure.
Embodiment 1
As shown in Figure 1, a kind of high temperature modification pressure balance type modulating valve, it is by the valve body 1 carrying valve seat, be installed on the sleeve 2 on valve body 1, gap is installed on the valve plug 3 in sleeve 2, and the band valve gap 4 of radiating structure and bottom are connected with valve plug and pass in the valve stem 5 of bonnet central, valve stem 5 and valve gap 5 and combined by stuffing box packing 6.When high temperature media is by valve body 1, due to conduction of heat, can make that valve plug 3 is same with valve stem 5 is in the condition of high temperature, because the deformation space of valve plug 3 can not affect use more greatly, valve stem 5 is then badly in need of heat radiation because deformation space is little, to keep its normal working, at this moment can by the contact of itself and valve gap 4 by carry heat to valve gap 4, and valve gap 4 utilizes the splintery radiating structure 7 of himself to shed heat to keep the normal working temperature of valve stem 5.In this embodiment, radiating structure 7 is vertical arrangement.
Embodiment 2
