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, in described valve body, be provided with the valve seat corresponding with flap, valve seat and valve body are integrally manufactured, and flap falls into after valve seat, between import and outlet, be cut off, flap departs from after valve seat, between import and outlet, is switched on, and fluid is passed through; Between valve gap and valve rod, be provided with stuffing box packing, be set with the gland for press seal filler on valve rod, 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 directly discharging unnecessary high-temperature hot-air to atmosphere, 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 being opened a temperature greatly about 1000 DEG C of left and right, and high temperature gas medium passes through very soon valve 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 tend to cause the high temperature deformation of valve rod and cause valve to work, the normal morphology that how to keep high temperature lower valve rod is in order to the normal work Cheng Liao valve manufacturing enterprise of the valve difficult problem solving of being eager.
Model utility content
The object of this part is to summarize some aspects of embodiment of the present utility model and briefly introduces some preferred embodiments.In this part and the application's specification digest and model utility title, may do a little simplification or omit to avoid the making object of this part, specification digest and model utility title fuzzy, and this simplification or omit and can not be used for limiting scope of the present utility model.
In view of the problem existing in above-mentioned and/or existing high temperature modification pressure balance type modulating valve and method for cleaning, the utility model is proposed.
Therefore, an object of the present utility model is to provide a kind of high temperature modification pressure balance type modulating valve, and it can make valve stem keep normal working morphology under the condition of high temperature.
For solving the problems of the technologies described above, the utility model 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 is arranged in sleeve and can does relative slippage, 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 form.
The utility model efficiently solves the yielding problem of pressure regulator valve family of power and influence bar of high-temperature pipe in the situation that increasing little cost.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment's technological scheme, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.Wherein:
Fig. 1 is the structural representation of a kind of high temperature modification pressure balance type modulating valve described in the utility model.
Fig. 2 is the structural representation of a kind of high temperature modification pressure balance type modulating valve described in the utility model
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with specific embodiment, embodiment of the present utility model is described in detail.
A lot of details are set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization without prejudice to the utility model intension in the situation that, and therefore the utility model is not subject to the restriction of following public specific embodiment.
Secondly, alleged " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the utility model herein.Different local in this manual " in one embodiment " that occur not all refer to same embodiment, neither be independent or the embodiment mutually exclusive with other embodiments optionally.
In figure, 1, valve body; 2, sleeve; 3, valve plug; 4, valve gap; 5, valve stem; 6, filler; 7, radiating structure.
As shown in Figure 1, a kind of high temperature modification pressure balance type modulating valve, it is by the valve body 1 that carries valve seat, be installed on the sleeve 2 on valve body 1, gap is installed on the valve plug 3 in sleeve 2, and valve gap 4 with radiating structure is connected with valve plug with bottom and the valve stem 5, valve stem 5 of passing valve gap center and valve gap 5 in combined by stuffing box packing 6.In the time that high temperature media passes through valve body 1, due to conduction of heat, can make valve plug 3 same with valve stem 5 in the condition of high temperature, because the deformation space of valve plug 3 more very much not can affect use, valve stem 5 is badly in need of heat radiation because deformation space is little, to keep its normal working, at this moment can bring valve gap 4 with contacting of valve gap 4 by heat by it, and valve gap 4 utilizes the splintery radiating structure 7 of himself heat to be shed to keep the normal working temperature of valve stem 5.In this embodiment, radiating structure 7 is vertical arrangement.
