Disclosure of utility model

The utility model aims to provide a full-jacket heat-insulating plug valve which completely wraps a valve of a connecting pipeline, and solves the heat insulation problem that a pipeline part is not heat-insulating steam or hot kerosene.

In order to achieve the above purpose, the present utility model provides the following technical solutions.

The embodiment of the application discloses a full jacket heat-insulating plug valve, which comprises a sleeve, enlarged flanges formed at two ends of the sleeve, a plug cock formed in the middle of the sleeve, a knob of the plug cock is sealed and protruded on the side wall of the sleeve, a shell is sleeved outside the sleeve, two ends of the shell are respectively connected with the two enlarged flanges in a sealing way, a sealing cavity is formed between the shell and the sleeve, and heat-insulating liquid is filled in the sealing cavity.

Preferably, in the full jacket thermal insulation plug valve, the rotation of the plug controls the on-off of the inside of the sleeve.

Preferably, in the above all-jacket thermal insulation plug valve, a sealing gasket is disposed between the plug and the sleeve.

Preferably, in the full jacket thermal insulation plug valve, a sealing cover is arranged at the knob.

Preferably, in the full jacket thermal insulation plug valve, two sides of the shell are respectively communicated with an external pipeline and are respectively used for circulating the thermal insulation liquid in and out.

Preferably, in the full jacket thermal insulation plug valve, a connecting flange is formed at an end of the external pipeline.

Compared with the prior art, the device has the advantages that the device is arranged on the chemical pipeline, the phenomenon that the crystallization or insufficient reflection of chemical materials in the pipeline are caused by insufficient heat preservation due to temperature reduction is avoided, the device ensures that the whole chemical pipeline is provided with heat preservation steam or heat preservation kerosene, the heat preservation of the valve connecting part is also very sufficient, and the pipeline exposed outside is avoided.

Drawings

Detailed Description

The following detailed description of the technical solutions according to the embodiments of the present utility model will be given with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, a full jacket thermal insulation plug valve 100 comprises a sleeve 101, enlarged flanges 102 formed at two ends of the sleeve 101, a plug 103 formed in the middle of the sleeve 101, a knob 104 of the plug 103 extending out of the side wall of the sleeve 101 in a sealing manner, a shell 105 sleeved outside the sleeve 101, two ends of the shell 105 respectively connected with the two enlarged flanges 102 in a sealing manner, a sealing cavity 106 formed between the shell 105 and the sleeve 101, and thermal insulation liquid filled in the sealing cavity 106. Rotation of the tap 103 controls the on-off of the interior of the sleeve 101.

In this embodiment, the on-off action of normal valve is realized through the inside break-make of cock control sleeve pipe to establish the shell through the outside cover of sleeve pipe to the intraductal temperature of leading in heat preservation liquid assurance sleeve keeps stable, has effectively solved the condition that pipeline commodity circulation temperature can't guarantee in the chemical industry.

Further, a gasket 107 is provided between the tap 103 and the sleeve 101. A sealing cap 108 is provided at the knob 104.

In this embodiment, it is ensured that the seal does not leak.

Further, both sides of the housing 105 are respectively connected to external pipes 109 for circulating the heat-insulating liquid. The end of the external connection 109 is formed with a connection flange 110.

In the embodiment, the heat preservation liquid is convenient to enter and exit, circulation flow is realized, and the internal temperature is ensured.
