Embodiment 1

[0016] Choose a single-coil solenoid valve. Before the solenoid valve is filled with glue, stick a glue filling hopper made of tin foil to the single glue outlet hole at the single coil. The glue opening is larger than the glue outlet hole, and the lower end of the glue filling hopper is pasted on the surface of the valve product. If the solenoid valve has an outlet hole, the outlet hole is stuck with plasticine to prevent the glue from flowing out during the glue injection and curing process. Put the solenoid valve to be glued into an electric blast drying oven, and dry it at a temperature of 75~85°C for 45~60min. Then inject the prepared glue from the glue outlet until the glue is 5-10mm higher than the glue outlet. The glue filling hopper can prevent the glue from flowing out during the curing process. It only needs to be filled once for curing. Finally, place the product with the glue outlet upward in an environment of 24-28°C, cure for about 12 hours, remove the residual ...

Embodiment 2

[0018] Choose a double-coil solenoid valve. Before the solenoid valve is filled with glue, glue two glue filling hoppers made of tin foil on the two glue outlet holes at the double coil. In contrast, the glue filling port is larger than the glue outlet hole, and the lower end of the glue filling hopper is pasted on the surface of valve products. If the solenoid valve has an outlet hole, the outlet hole should be stuck with plasticine to prevent the glue from flowing out during the glue injection and curing process. . Put the solenoid valve to be glued into an electric blast drying oven, and dry it at a temperature of 75~85°C for 45~60min. Then inject the prepared glue from the glue outlet until the glue is 5-10mm higher than the glue outlet. The glue filling hopper can prevent the glue from flowing out during the curing process. It only needs to be filled once for curing. Finally, place the product with the glue outlet upward in an environment of 24-28°C, cure for about 12 ho...

Embodiment 3

[0020] Choose a single-coil self-locking valve. Before the self-locking valve is filled with glue, stick a glue filling hopper made of tin foil on the single glue outlet hole at the single coil. The glue filling port at the bottom of the glue hopper is opposite to the glue outlet. And the glue filling port is larger than the glue outlet hole. The lower end of the glue filling bucket is pasted on the surface of valve products. If the self-locking valve has an outlet hole, the outlet hole is stuck with plasticine to prevent the glue from flowing out during the glue injection and curing process. Put the self-locking valve to be glued into the electric blast drying oven, and dry it at a temperature of 75~85°C for 45~60min. Then inject the prepared glue from the glue outlet until the glue is 5-10mm higher than the glue outlet. The glue filling hopper can prevent the glue from flowing out during the curing process. It only needs to be filled once for curing. Finally, place the produ...

Abstract

The invention provides a glue pouring method for a valve product. The glue pouring method comprises the following steps: a, arranging a glue pouring bucket at a glue outlet hole of the valve product,wherein the glue pouring port in the lower part of the glue pouring bucket is opposite to the glue outlet hole, and the glue pouring bucket is attached to the surface of the valve product; b, injecting a glue solution from the glue outlet hole to the glue pouring part of the valve product till the glue solution is higher than the glue outlet hole; and c, after the glue solution is cured, removingresidual glue solution on the surfaces of the glue pouring bucket and the glue outlet hole. The glue pouring method provided by the invention has the advantages that in a pouring process of the valveproduct, by adhering the bucket with a tinfoil at the glue outlet hole, primary glue pouring is achieved, so that the labor intensity of an operator is reduced and the production efficiency is improved. The method provided by the invention is concise and feasible. The glue-poured valve product by means of the method is excellent in insulating property.

Description

technical field [0001] The invention relates to the manufacture and production of valve products, in particular to a glue filling method for valve products. Background technique [0002] Valve products are widely used in industry. For example, in the aerospace field, a few valve products are used at least, and dozens of valve products are used at most. The aerospace field has relatively high insulation performance requirements for valve products. Glue filling is a key process to ensure the insulation performance of valve products. [0003] The current glue filling method for valve products is to inject glue into the glue hole. When the glue is level with the glue hole, stop the glue injection. During the curing process, the glue gradually hardens and the glue level drops. Therefore, during the curing process of the glue, it is necessary to replenish the glue in the glue hole many times to ensure that the glue can be level with the glue hole after the glue is completely cure...
