Embodiment

[0020] Such as figure 1 , 2 As shown, the present invention is aimed at the manufacture method of respirator protective cover, comprises the following steps:

[0021] A: Prepare the waterproof cloth 3 and the double-head zipper 2, cut the waterproof cloth 3 into two rectangles of equal size, and then spread polyethylene foam cotton 4 between the two waterproof cloth 3, and use the sealant to seal the polyethylene foam. The foam 4 is fixed to the two waterproof cloths 3, and then the edges of the waterproof cloths 3 are sequentially sewed with silk threads to complete the production of the protective cover body;

[0022] B: Open a liquid level observation port 5 on the protective cover body, and suture the surroundings of the liquid level observation port 5 with silk thread;

[0023] C: Then fix the side cloths on both sides of the double-ended zipper 2 and the two ends of the sewed protective cover body respectively. When the double-ended zipper 2 is sealed and locked, the p...

Abstract

The invention discloses a method for making a respirator protective cover, which includes the following steps: A: Prepare a waterproof cloth and a double-headed zipper, cut the waterproof cloth into two equal-sized rectangles, and then spread a waterproof cloth between the two waterproof cloths. Polyethylene foamed cotton, use sealant to fix polyethylene foamed cotton and two waterproof cloths, and then use silk thread to sew the edges of the waterproof cloths in turn to complete the production of the protective cover body; B: open a liquid level on the protective cover body Observation port, and suture the surroundings of the liquid level observation port with silk thread; C: Then fix the two side cloths of the double-ended zipper and the two ends of the sewn protective cover body respectively, when the double-ended zipper is sealed and locked, the The protective cover body forms a sleeve. The invention solves the problem that external water vapor easily enters the respirator through the cracks when the glass is shaken and cracks are generated.

Description

technical field [0001] The invention relates to the technical field of transformer maintenance, in particular to a manufacturing method for a respirator protective cover. Background technique [0002] Transformer respirator is also called transformer moisture absorber, or transformer silica gel tank, transformer desiccant, and is generally installed at the end of the pipeline where the oil conservator communicates with the air. A common transformer respirator is mainly composed of an iron pipe, a glass container and an oil cup, with a desiccant inside, and a certain amount of insulating oil in the oil cup. Its function is to absorb the moisture in the air entering the oil pillow plastic bag and diaphragm, remove and dry the sundries and moisture in the air entering the transformer or oil conservator due to the change of transformer oil temperature, so as to prevent the transformer from being damp and ensure the transformer oil dielectric strength. [0003] In order to faci...
