Detailed Description
The invention is further illustrated with reference to the following figures and examples.
Referring to fig. 1-2, a welding protection tool for a valve body provided for an embodiment includes a protection tube 1 and water-absorbing cloth 2, the water-absorbing cloth is wrapped on the inner wall and the outer wall of the protection tube 1, the thickness of the water-absorbing cloth can be set according to actual conditions, the wrapped protection tube is the water-absorbing cloth on the inner wall and needs to be attached to a valve body 5 needing to be welded, and the water-absorbing cloth inside the protection tube is soft, so that the inner diameter of the protection tube after wrapping the water-absorbing cloth is smaller than the outer diameter of the valve body, and the protection tube can be tightly sleeved outside the valve body 5, has a certain fixing effect, and can absorb heat on the valve body 5. The effect of cooling can be played in the welding, the effect of protection valve body has also been played, as to what the cloth winding that absorbs water can be according to actual conditions, need not the extravagant cloth that absorbs water of transition. When the tool is used, a method of winding wet cloth does not need to be used like the conventional scheme, time and labor are consumed, and the wound wet cloth needs to be slowly taken down for one circle after welding; the tool for soaking water is directly sleeved on the valve body to be welded, and after welding is finished, the tool is directly pulled out, so that a large amount of labor force is saved, time is saved, and labor cost for manufacturing products is reduced.
In this embodiment, a positioning opening 11 is further provided at one end of the protection tube, the positioning opening plays a role of positioning, a branch tube 4 perpendicular to the valve body is provided at the side of some valve bodies 5 (as shown in fig. 3-4), the size of the positioning opening is designed to match the diameter of the branch tube 4, thus the opening can be directly aligned with the branch tube 4 during installation, which brings convenience to welding work, ensures the installation consistency of the tool, and can block the valve body to protect the valve body. The end of the protective pipe is provided with a piece of marking cloth with other colors, which can increase the positioning effect of the opening, make the clamping force at the position slightly larger, and increase the water absorption capacity at the position and the heat insulation capacity.
In this embodiment, the length of protection tube will be greater than or equal to the length of the valve body that needs the welding, and it all wraps up including it needs the valve body is whole, ensures the guard action of this frock to the valve body. The water-absorbing cloth is made of gauze, has good water absorption, and is firmly adhered with medical adhesive plaster outside the water-absorbing cloth, so that the water-absorbing cloth cannot be scattered. The protection tube is a plastic rubber tube, the plastic rubber tube is preferably made of PVC materials, the materials are selected, the heat insulation performance is good, and the protection force on the valve body is stronger during welding.
In other embodiments, the thicker water-absorbing cloth is directly adhered to the inner wall of the protection pipe and has water absorption, and the water-absorbing cloth on the inner wall is matched with the outer wall of the valve body to achieve the functions of protection and heat insulation.
The invention also discloses a manufacturing process of the welding protection tool for the valve body, which comprises the following specific steps:
preparing water-absorbing cloth, a protection tube, a high-temperature-resistant adhesive tape and medical adhesive plaster, wherein the width of the water-absorbing cloth is matched with the length of the inner circumference of the protection tube;
step two, the water absorption cloth penetrates into one end of the protection tube and extends out of the other end of the protection tube, a section of length is extended out, two long edges of the water absorption cloth are connected and rolled (namely, the water absorption cloth is attached to the inner wall of the protection tube), and the water absorption cloth can be attached to the inner wall of the whole protection tube because the width of the water absorption cloth is consistent with the perimeter of the inner circle of the protection tube;
aligning two long edges of the water absorption cloth with the positioning opening, preferably aligning the two long edges of the water absorption cloth with the positioning opening, so that the positioning bayonet is easily clamped on the branch pipe 4, then flanging one end of the water absorption cloth close to the positioning opening outwards, and wrapping the end part of the protection pipe with the positioning opening so as to attach the end part to the outer wall of the protection pipe;
