Abstract
The utility model discloses a thermal-insulation plug valve, which includes a valve body, a valve seat and a plug cock arranged in the valve body, a valve rod fixedly connected with the plug cock, a handle fixedly connected with the valve rod, and a sealing device arranged between the valve rod and the valve body, wherein the valve seat is arranged between the plug cock and the valve body, a valve sleeve is arranged outside the valve body, and the valve sleeve and the valve body are fixedly connected to form a valve cavity. The thermal-insulation structure of the thermal-insulation plug valve can realize the thermal-insulation of the medium passing through the valve, and the thermal-insulation plug valve has better sealing performance and better practicability.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of stopcock with heat insulation function.
Background technique
The working principle of stopcock is, by the rotation cock, passway in the cock is communicated with passway on the valve body or separate, and then a kind of valve of realize opening or closing, the shape of its cock can be cylindrical or conical, the passage of cylindrical cock is generally rectangular, and the passage of conical cock generally in echelon.The special construction of stopcock makes it have characteristics such as simple in structure, that keying is rapid, fluid resistance is little, is applicable to cut-out, connection and the shunting of medium, also can be used for throttling sometimes.
When medium need be incubated, though the design about pipe insulation is a lot, the design of closing valve insulation is seldom arranged, the stopcock with heat insulation function of Chinese patent 200820030205.4 designs is that cock is divided into two-stage, and being filled with resistant to elevated temperatures stuffing box packing, material uses heat-resisting steels, and heating resistance collar is set outside valve body, structure is complicated, and cost is higher.Therefore how can realize the difference insulation requirement of different medium easily, become the problem that needs solution.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of insulation stopcock, the insulation of medium of valve that can realize flowing through of the insulating structure of this stopcock setting, and have the better seal performance.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of insulation stopcock, comprise valve body, be arranged on valve seat in the described valve body and cock, the valve rod of fixedlying connected, the handle of fixedlying connected with described valve rod with described cock, and the seal arrangement between described valve rod and described valve body, described valve seat is between described cock and described valve body, the outer installment of described valve body has valve pocket, and described valve pocket and described valve body are fixed together and form valve pocket.
Preferably, described valve pocket is provided with the connection mouth that is in communication with the outside.
Preferably, described connection mouth comprises import and outlet.
Preferably, the inboard of described valve pocket is provided with heat insulation layer.
Preferably, described valve body top also is provided with valve gap, described valve gap by bolton on described valve body.
Pass through technique scheme, the stopcock that the utility model provides, outer installment at valve body has the valve pocket that connects as one with it, and form valve pocket between valve body and the valve pocket, valve pocket is provided with two connection mouths of import and outlet of thermal insulation medium, when thermal insulation medium circulates, can play insulation effect to the medium of the valve of flowing through, and the heat insulation layer of valve sleeving inner wall has played the insulation effect to thermal insulation medium again in valve pocket.The insulation of this model utility is provided with simple in structure, and dual heat insulation effect is better, and has further improved the overall sealing performance of valve with the valve gap that valve body tightens together, and has good practicability.
Description of drawings
In order to be illustrated more clearly in the technological scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below.
Fig. 1 is the disclosed a kind of structural representation that is incubated stopcock of the utility model embodiment;
Fig. 2 is the disclosed a kind of flow schematic diagram that is incubated thermal insulation medium in the stopcock of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described.
The utility model provides a kind of insulation stopcock, the insulation of the medium of the valve of can realizing flowing through, and have better seal, practicability is better.
According to Fig. 1, the disclosed stopcock of the utility model, comprise valve body 11, be arranged on valve seat 12 in the valve body 11 and cock 13, the valve rod 14 of fixedlying connected, the handle 15 of fixedlying connected with valve rod 14 with cock 13, and the seal arrangement 16 between valve rod 14 and valve body 11, valve seat 12 is between cock 13 and valve body 11.The outer installment of valve body 11 has valve pocket 17, and links together with valve body 11 and form valve pocket 19, and valve pocket 19 is provided with 22 two connection mouths of import 21 and outlet that are in communication with the outside, and the inwall of valve pocket 17 is provided with one deck heat insulation layer; Valve body 11 tops also are provided with valve gap 18, and valve gap 18 and valve body 11 are fixedlyed connected by bolt and nut.
In the time need being incubated to the medium of the valve of flowing through, with reference to figure 2, only need thermal insulation medium 23 circulation loops are connected respectively the import 21 and outlet 22 of valve pocket 19, start recycle pump, thermal insulation medium 23 enters from import 21, flow out and the storage tank of circulation turnover thermal insulation medium 23 from exporting 22 then, thereby form thermal insulation medium 23 circulating between valve pocket 19 and storage tank, and play the effect that the medium to the valve of flowing through is incubated.In addition, be provided with one deck heat insulation layer at valve pocket 19 inwalls, this heat insulation layer has guaranteed that 23 media with the valve of flowing through of thermal insulation medium carry out exchange heat, and does not have exchange heat with the external world, has reduced energy loss.This valve also is provided with valve gap 18, and valve gap 18 closely is fixed together by bolt and nut and valve body 11, and is provided with seal arrangement 16 in the cavity that forms of valve gap 18, valve body 11 and valve rod 14, therefore, has further guaranteed the sealability of this valve.
The disclosed valve of this model utility, the thermal insulation mediums 23 that can circulate in the valve pocket 19 that the valve pocket 17 of its valve body 11 outer installment and valve body 11 form, the heat insulation function of the medium of the valve of can realizing flowing through adds the heat insulation layer that valve sleeving inner wall is provided with, dual insulation, effect is splendid; The valve gap 18 of its setting, and the seal arrangement 16 that is provided with between valve gap 18 and valve body 11, the valve rod 14 makes the sealability of valve improve widely, the life-span of valve is longer.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
