Abstract
The utility model discloses a large valve device of a vacuum welding chamber. The large valve device comprises a vacuum chamber body, a steam cylinder and a large valve, wherein the vacuum chamber body is connected with the large valve, a valve plate is arranged inside the large valve at the connection position, the steam cylinder is installed at one end of the large valve, which is opposite to the vacuum chamber body, and a pipeline which is communicated with the atmosphere is arranged on one side of the large valve. According to the large valve device, the valve plate is arranged at the connection position between the large valve and the vacuum chamber body, the steam cylinder is installed opposite to the valve plate, and the pipeline which is communicated with the atmosphere is arranged on one side of the large valve, so that the air enters the large valve and applies pressure to the valve plate, the valve plate is pressed tightly, the tightness is good, no additional pressure application is required, and the device is not easy to damage.
Description
Technical field
The utility model belongs to welding technology field, the big valve gear of especially a kind of vacuum welding equipment.
Background technology
At present; The big valve gear of existing vacuum welding equipment generally all is that the side of big valve links to each other the two ends that are arranged on big valve that cylinder and pipeline are relative with vacuum chamber; Valve plate is positioned at the position that pipeline links to each other with big valve like this, and air just can back down valve plate through pipeline and get into vacuum chamber like this.If need to guarantee that the vacuum state in the vacuum chamber just needs extra exerting pressure, waste energy very much, and damage easily.
The utility model content
To the deficiency that exists in the prior art, the purpose of the utility model is to provide a kind of can play sealing function to vacuum chamber by external atmospheric pressure, saves the energy, the big valve gear of non-damageable vacuum welding equipment.
The utility model adopts following technical scheme to realize its purpose: the big valve gear of a kind of vacuum welding equipment; Mainly comprise vacuum chamber, cylinder and big valve; It is characterized in that: vacuum chamber links to each other with big valve; And be provided with valve plate in the big valve in junction, cylinder is installed in the other end of the big valve relative with vacuum chamber, and big valve one side is provided with the pipeline with atmosphere.
The beneficial effect that the technical scheme that adopts the utility model to provide can reach is: big valve of the utility model and vacuum chamber junction are provided with valve plate; The cylinder that is equipped with on the other side is provided with the pipeline with atmosphere in big valve one side, and air gets into big valve valve plate is exerted pressure like this; Make valve plate push up more tight and more tight; Sealing is good more, does not need extra exerting pressure, and not fragile.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1; Be the utility model structural representation, the big valve gear of a kind of vacuum welding equipment mainly comprises vacuum chamber 4, cylinder 1 and big valve 2; Vacuum chamber 4 links to each other with big valve 2; And be provided with valve plate 3 in the big valve 2 in junction, cylinder 1 is installed in the other end of the big valve 2 relative with vacuum chamber 4, and big valve 2 one sides are provided with the pipeline 5 with atmosphere.Big valve of the utility model and vacuum chamber junction are provided with valve plate; The cylinder that is equipped with on the other side is provided with the pipeline with atmosphere in big valve one side, and air gets into big valve valve plate is exerted pressure like this; Make valve plate push up more tight and more tight; Sealing is good more, does not need extra exerting pressure, and not fragile.
