Abstract
The utility model relates to a heat preservation ball valve, including a valve body, a valve stem, a valve spool, and a heat preservation jacket outside the valve body. A heat insulating layer is formed between the heat preservation jacket and the valve body. The valve body is directly provided with four connecting through holes which are symmetrically arranged around the valve spool. The utility model overcomes the problems of the prior art that prior heat preservation ball valves have large volume, few flux, weak heat preservation effect, and poor sealing property. Via the foregoing design, pre-requisite flange used to connect valve are reduce; the whole structure of the heat preservation ball valve is greatly simplified; the volume is shrunk, the real diameter arrives to 95%. The utility model has the advantages of large flux, strong sealing property, and well heat preservation effect.
Description
Affiliated technical field
The utility model relates to a kind of Thermal insulating ball valve.
Background technique
Traditional Thermal insulating ball valve all is the insulation Flange Ball Valves, and a kind of be split-type structural, and its valve body and valve gap are incubated respectively, exist volume greatly, complex structure, leak outside easily, the problem of heat insulation effect difference; Another kind of imbed structure for undergauge integral type valve gap, its insulation jacket adopts the split welding, and actual inside nominal diameter has only 80%, so has also that volume is big, flow is little, the defective of poor sealing performance.
Summary of the invention
The volume of Thermal insulating ball valve is big in the prior art, flow is little in order to overcome, the problem of heat insulation effect and poor sealing performance, and the utility model provides a kind of Thermal insulating ball valve, this Thermal insulating ball valve simple in structure, volume is little, flow is big, high insulating effect.
The technological scheme that its technical problem that solves the utility model adopts is: comprise valve body, valve rod and spool, valve body is provided with insulation jacket outward, forms thermal insulation layer between insulation jacket and valve body, and connecting through hole directly is set on valve body.
Connecting through hole is symmetrical arranged four around spool.
The utility model has reduced valve and has connected necessary flange by above-mentioned design, has simplified the overall structure of Thermal insulating ball valve greatly, has dwindled volume, its actual latus rectum reaches 95%, has that flow is big, sealability strong, the advantage of high insulating effect.
Description of drawings
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1.
Embodiment
As shown in the figure, the utility model comprises valve body 1, valve rod 2 and spool 3, the valve body 1 outer insulation jacket 4 that is provided with, and 1 of insulation jacket 4 and valve body form thermal insulation layer 5, and connecting through hole 6 directly is set on valve body 1, and connecting through hole 6 is symmetrical arranged four around spool 3.Under assembling condition, valve body 1 directly links to each other with pipeline by connecting through hole 6, connects necessary flange thereby reduced valve, reaches overall structure, reduced volume, the augmented flow of simplifying Thermal insulating ball valve, the purpose of improving thermal insulation property.
Claims (2)
1, a kind of Thermal insulating ball valve comprises valve body, valve rod and spool, and valve body is provided with insulation jacket outward, forms thermal insulation layer between insulation jacket and valve body, it is characterized in that directly being provided with on valve body (1) connecting through hole (6).
2, Thermal insulating ball valve according to claim 1 is characterized in that connecting through hole (6) is symmetrical arranged four on every side at spool (3).
