Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0016] refer to figure 2 with image 3 , a liquefied gas cylinder valve sealing sleeve with hygienic function, the sealing sleeve includes a sealing sleeve upper part 201 that can wrap the valve handwheel and a sealing sleeve lower part 203 that can wrap the valve body, and the sealing sleeve upper part and the sealing sleeve Between the lower parts of the sleeve and along the circumferential direction of the sealing sleeve, a tear line 202 consisting of several holes for easy tearing is provided. When the lower portion 203 of the sealing sleeve wrapped on the valve body is torn apart, the lower 203 can only be separated from the closure sleeve upper part 201 wrapped on the valve handwheel along the tearing line 202, thereby retaining the film wrapped on the valve handwheel.

[0017] The optimal size of the hole on the tearing line of the s...

Abstract

The invention belongs to the technical field of prevention of a liquefied gas cylinder valve from being opened abnormally, and particularly relates to a liquefied gas cylinder valve sealing sleeve with a sanitation function. According to the liquefied gas cylinder valve sealing sleeve, the problem that a valve hand wheel is polluted by other people during the inflation of a liquefied gas cylinder is solved, a tearing line which is convenient to tear and consists of a plurality of holes is arranged between the upper part of the sealing sleeve and the lower part of the sealing sleeve along the circumferential direction of the sealing sleeve, and a thin film wrapping the valve hand wheel can be retained when the sealing sleeve is torn off, so that the polluted valve hand wheel is isolated by the thin film. Original functions of the sealing sleeve are maintained, and meanwhile, a pollution isolating function is easily obtained; moreover, the sealing sleeve is more easily torn off compared with the prior art, and has the advantages that the functions are added while the original functions are not reduced, the using steps are not increased, and the product cost is not increased.

Description

technical field [0001] The invention belongs to the technical field of preventing the valve of a liquefied gas cylinder from being opened abnormally, and in particular relates to a sealing sleeve for a valve of a liquefied gas cylinder with a hygienic function. Background technique [0002] The sealing sleeve of the civil liquefied gas cylinder valve is made of heat-shrinkable plastic film. After the liquefied gas cylinder is inflated, the sealing sleeve is placed on the valve, and then the sealing sleeve is heated. The sealing sleeve is heated and shrinks to wrap the valve handwheel and the valve body. The entire valve inside, in order to be able to protect the valve and prevent others from opening the valve during transportation and sales. When using liquefied petroleum gas, tear off all the sealing sleeves wrapped on the valve, and then the valve can be operated. So the sealing sleeve of the liquefied gas cylinder valve has no other functions except the above-mentioned f...
