Abstract
The utility model discloses a polymeric kettle material discharge valve, which comprises a valve body, wherein a valve cavity is arranged in the valve body, a valve core and a valve seat which are mutually matched are arranged in the valve cavity, the outer wall of the valve body is provided with a material inlet opening and a material outlet opening communicated with the valve cavity, connecting flanges are respectively arranged on the material inlet opening and the material outlet opening, a heat insulation sandwich sleeve is arranged in the valve body on the periphery of the valve cavity between the two connecting flanges, a hot medium inlet opening and a hot medium outlet opening communicated with the heat insulation sandwich sleeve are also respectively arranged on the outer wall of the valve body, and the heat insulation sandwich sleeve mainly consists of spiral flow passages arranged in the valve body on the periphery of the valve cavity in a coil mode. The utility model adopts the technical scheme, when a hot medium flows in the spiral flow passage arranged on the periphery of the valve cavity, and the flowing path of the hot medium is limited by the spiral flow passage, so the phenomena of heat transmission dead corner and hot medium short circuit can be avoided, in addition, the contact time of the hot medium and the valve body can be prolonged, so the sufficient heat transfer between the hot medium and the valve body can be realized, the heat transfer efficiency of the hot medium can be improved, and the quality of materials flowing through the valve cavity can be ensured.
Description
Technical field
The utility model relates to a kind of valve, definite saying so relate to a kind of can be to the polymeric kettle discharge valve of the liquid material preservation and controlling that flows through in the valve body.
Background technique
In the production process of existing chemical material, in the course of conveying of high-temperature material,, can use the polymeric kettle discharge valve that can be incubated the material that flows through by steam or heat conduction wet goods heating agent usually for preventing that material from condensing in valve place cooling.As the patent No. is that the Chinese utility model patent specification of ZL92220051.3 discloses a kind of insulation feed end, this insulation feed end comprises the valve core case that matches with spool, be respectively equipped with the import and export of material on the axial both sides valve body of valve core case, be respectively equipped with adpting flange in the import and export, on spool, be connected with the valve rod that drives its action, be provided with insulation jacket between two adpting flanges on the periphery of valve body.But should be incubated the as a whole cavity of insulation jacket on the feed end, form heating agent " dead angle " or heating agent " short circuit " phenomenon in cavity, occurs at the two ends up and down of cavity easily when heating agent flows through in cavity, cause the heat transfer of heating agent inhomogeneous, the efficient of conducting heat is lower, thereby has influenced from the quality of the material of this insulation feed end process.
The model utility content
The purpose of this utility model is at above-mentioned defective, provides a kind of polymeric kettle discharge valve conduct heat " dead angle " or heating agent " short circuit " phenomenon to occur to avoid heating agent in insulation jacket.
The technical solution of the utility model is: a kind of polymeric kettle discharge valve, comprise valve body, be provided with valve pocket in the valve body, spool that cooperatively interacts in the valve pocket and valve seat, valve outer wall is provided with the material import and export that is communicated with valve pocket, on material import and export, be respectively equipped with adpting flange, be provided with insulation jacket in the valve body of the valve pocket periphery between two adpting flanges, also be respectively equipped with the heating agent that is communicated with insulation jacket and import and export on the outer wall of valve body, described insulation jacket mainly is made of the helical flow path that coiling is arranged in the peripheral valve body of valve pocket.
Described helical flow path is formed every establishing by the dividing plate that coiling is arranged between the insulation jacket inside and outside wall.
The utility model adopts technique scheme, when heating agent flows through in the peripheral helical flow path that is provided with of valve pocket, the route that heating agent is flowed through is limited by helical flow path, thereby can avoid occurring the phenomenon of heat transfer " dead angle " and heating agent " short circuit ", and can prolong the time of contact of heating agent and valve body, make between heating agent and the valve body and to realize fully conducting heat, improve the heating agent heat transfer efficiency, the quality of the material of the valve pocket of guaranteeing to flow through.
Description of drawings
Fig. 1 is the structural representation of the utility model insulation valve body.
Embodiment
As shown in Figure 1, the polymeric kettle discharge valve comprises valve body 1, and the inside of valve body 1 is provided with valve pocket, is provided with the spool 2 and the valve seat 4 that complement one another in the valve pocket, is connected with handwheel by valve rod on the spool 2.Radially be provided with respectively in the both sides of valve body 1 and valve pocket is communicated with, direction is opposite material inlet 101 and material outlet 102.On material inlet 101, be provided with adpting flange 5, material outlet 102 is provided with adpting flange 6, be provided with insulation jacket in the peripheral valve body of valve pocket between two adpting flanges 5,6, this insulation jacket is made of every establishing the helical flow path 7 that forms the dividing plate 3 that coiling is arranged between the chuck inside and outside wall.In the present embodiment, inside at two adpting flanges 5,6 is equipped with the heat insulation cavity 8 that is communicated with the insulation jacket layer around material import and export respectively, radially is provided with the heating agent that is communicated with toroidal cavity 8 respectively and imports and exports 201,202 on the outer wall of two adpting flanges 5,6.
The utility model in use, heating agent flows out from the heating agent outlet on another flange through helical flow path by the heating agent import on one of them adpting flange, thereby the road of flowing through of heating agent is limited enforceable peripheral mobile around valve pocket by helical flow path, thereby avoided heating agent to conduct heat at " dead angle " and heating agent " short circuit " phenomenon through out-of-date appearance at valve body, and because heating agent is forced to advance around the valve pocket spiral by helical flow path, thereby can prolong the time of contact of heating agent and valve body, make and realize between the heat that carries in the heating agent and the valve body conducting heat fully, strengthen the heat transfer efficiency of heating agent.
The utility model is not limited to the foregoing description; those skilled in the art need not pay the thermal insulation valve with spirality heating agent insulation runner that creative work can be expected other structure or shape according to the foregoing description; for example; spiral insulation heating agent runner can also be made of the heat conduction coil pipe that is coiled in the valve pocket periphery; no matter but how its structure and shape change; so long as the valve pocket periphery of its valve body is provided with spiral heating agent runner, all within protection domain of the present utility model.
Claims (2)
1. polymeric kettle discharge valve, comprise valve body, be provided with valve pocket in the valve body, spool that cooperatively interacts in the valve pocket and valve seat, valve outer wall is provided with the material import and export that is communicated with valve pocket, on material import and export, be respectively equipped with adpting flange, be provided with insulation jacket in the valve body of the valve pocket periphery between two adpting flanges, also being respectively equipped with the heating agent that is communicated with insulation jacket on the outer wall of valve body imports and exports, it is characterized in that described insulation jacket mainly is made of the helical flow path that coiling is arranged in the peripheral valve body of valve pocket.
