The vacuum furnace argon gas collecting device comprises a pressure gauge, a first valve, a four-way connection, a second valve, a third valve and a fourth valve, wherein one end of the first valve is connected with a left argon gas bomb through a gas-supply pipe, the other end of the first valve is sequentially connected with the pressure gauge and the four-way connection through gas-supply pipes, the four-way connection is respectively connected with one end of the second valve, one end of the third valve and one end of the fourth valve through gas-supply pipes, the other end of the third valve is connected with a right argon gas bomb through a gas-supply pipe, and the other end of the fourth valve is connected with a vacuum furnace body through a gas-supply pipe. The invention has the beneficial effect that when the argon gas bombs are changed, air admission can be effectively prevented.
Description
Technical field
The present invention relates to a kind of vacuum drying oven argon gas collector-shoe gear for the preparation of magnetic material, belong to the collector-shoe gear technical field.
Background technology
Sintering furnace and smelting furnace all are the main vacuum equipments of preparation magnetic material; when being prepared; for preventing material oxidation; generally argon gas is passed in the vacuum furnace body as protective gas; because the character of argon gas is torpescence very; can not burn; not combustion-supporting yet; so can well prevent the material oxidation for preparing; present most of vacuum furnace body all is directly to carry out the supply of argon gas by argon bottle, when one bottle of gas uses when changing, the part air is entered in the air delivering pipeline; so just may cause the oxidation of material, reduce the qualification rate of product.
Summary of the invention
Problem for above-mentioned prior art exists the invention provides a kind of vacuum drying oven argon gas collector-shoe gear for the preparation of magnetic material, when carrying out the argon bottle replacing, can effectively stop air to enter.
To achieve these goals, the technical solution used in the present invention is: a kind of vacuum drying oven argon gas collector-shoe gear for the preparation of magnetic material, comprise Pressure gauge, the first valve, four-way connection, the second valve, the 3rd valve and the 4th valve, one end of the first valve is connected by air delivering pipeline with left argon bottle, the other end of the first valve is connected with four-way connection with Pressure gauge successively by air delivering pipeline, four-way connection by air delivering pipeline respectively with an end of the second valve, one end of the 3rd valve connects with an end of the 4th valve, the other end of the 3rd valve is connected by air delivering pipeline with right argon bottle, and the other end of the 4th valve is connected by air delivering pipeline with vacuum furnace body.
Further, vacuum furnace body is sintering furnace or smelting furnace.
The invention has the beneficial effects as follows: simple to operate, easy to use, when carrying out the argon bottle replacing, can effectively stop air to enter, thereby the material that effectively guarantees preparation can be not oxidized, improve the qualification rate of product.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, left argon bottle, 2, Pressure gauge, the 3, first valve, the 4, second valve, 5, four-way connection, the 6, the 4th valve, 7, right argon bottle, the 8, the 3rd valve, 9, vacuum furnace body.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of vacuum drying oven argon gas collector-shoe gear for the preparation of magnetic material, comprise Pressure gauge 2, the first valve 3, four-way connection 5, the second valve 4, the 3rd valve 8 and the 4th valve 6, one end of the first valve 3 and left argon bottle 1 are connected by air delivering pipeline, the other end of the first valve 3 is connected with four-way connection with Pressure gauge 2 successively by air delivering pipeline and is connected, four-way connection 5 by air delivering pipeline respectively with an end of the second valve 4, one end of one end of the 3rd valve 8 and the 4th valve 6 connects, the other end of the 3rd valve 8 and right argon bottle 7 are connected by air delivering pipeline, and the other end of the 4th valve 6 and vacuum furnace body 9 are connected by air delivering pipeline.
Vacuum furnace body 9 is sintering furnace or smelting furnace, and in the process of preparation magnetic material, two kinds of vacuum furnace body all need to be filled with argon gas and prevent material oxidation, and this device can be contained on sintering furnace or the smelting furnace.
