Description

A rubber valve core for the torch solenoid valve of the lower chute in the galvanized line furnace area

technical field

The utility model relates to the field of electric control valves, in particular to a rubber spool used for a torch electromagnetic valve of a lower chute in an galvanized wire furnace area.

Background technique

At present, in the galvanizing equipment in the galvanizing line furnace area, the solenoid valve core controlling the small torch is often scalded by high-temperature zinc ash due to its inability to withstand high temperatures, resulting in poor sealing of the valve core when the solenoid valve is closed. The structure is an integrated rubber diaphragm with a thickness of 1-2mm, which is particularly easy to be damaged at high temperature, resulting in a large amount of reduced hydrogen in the lower chute being burned and lost, and has a certain impact on the furnace pressure control, so that the galvanized products Quality suffers somewhat.

Contents of the invention

The purpose of this utility model is to provide a rubber valve core for the torch electromagnetic valve of the lower chute of the galvanized wire furnace area, which improves the structure, improves the high temperature resistance of the valve core, enhances the airtightness of the valve core, and reduces the hydrogen leakage in the lower chute. row, saving gas consumption, ensuring safe production, so that the pressure in the furnace area can be effectively controlled during galvanized production, avoiding the occurrence of exposed iron, and improving the product success rate.

In order to achieve the above object, the technical solution of the utility model is:

A rubber valve core for torch electromagnetic valve of the lower chute in the galvanized line furnace area, the diameter D of the diaphragm center is in the range of 80-90, the thickness h2 is 8-10 mm, and the thickness h1 of the diaphragm edge is 4-5 mm.

Compared with the prior art, the utility model has the beneficial effects of improving the strength of the diaphragm, effectively prolonging the service life of the solenoid valve, saving the consumption of spare parts, making the equipment run more safely and stably, and improving The control of furnace pressure and steel plate surface quality affected by damage can improve the success rate of products.

Detailed ways

The specific embodiment of the utility model will be further described below in conjunction with accompanying drawing:

See Figure 1, which is a structural schematic diagram of an embodiment of the rubber valve core for the torch solenoid valve in the lower chute of the galvanized wire furnace area of the present invention. The diameter D of the diaphragm core 1 is 80-90 and the thickness h2 is 8-90. 10mm, the core of the diaphragm is connected with the connecting piece of the valve body, and the thickness h1 of the diaphragm edge 2 is 4-5mm. The external size of the diaphragm and the size of the flange hole are designed according to the connection size of the solenoid valve, and the material of the diaphragm is high temperature resistant silicone rubber.

After the implementation, the damage degree of the electromagnetic valve core has been significantly reduced, and at the same time, about 10.5 tons of exposed iron defects can be reduced every month, and the annual savings are considerable.

Claims (1)

1. one kind is used for chute torch solenoid valve rubber spool under the aluminum-zinc alloy line oven district, it is characterized in that, the diameter D of diaphragm heart portion is that the thickness h 2 in 80～90mm scope is 8～10mm, and diaphragm edge thickness h 1 is 4～5mm.
