Vacuum system high-efficiency liquid discharging device

Abstract

The invention relates to the technical field of vacuum equipment, in particular to a vacuum system high-efficiency liquid discharging device. The vacuum system high-efficiency liquid discharging device comprises a vacuum tank. The bottom of the vacuum tank is provided with a liquid outlet. The vacuum system high-efficiency liquid discharging device further comprises a liquid storage tank, a liquiddischarging pipe, a one-way electromagnetic valve, a stopper, a sliding rod, a limiting block, a first spring, a piston, a sliding plug, a driving rod, a floating plug, a limiting ring and a second spring. The vacuum system high-efficiency liquid discharging device has the beneficial effects that automatic and high-efficiency liquid discharge is achieved, in addition, external air cannot participate in the liquid discharging process, thus, the vacuum tank is in a vacuum state in the liquid discharging process, and the vacuum state of the vacuum system is maintained when the liquid dischargingoperation is conducted.

Description

Technical field [0001] The invention relates to the technical field of vacuum equipment, in particular to a high-efficiency draining device for a vacuum system. Background technique [0002] When the existing vacuum system is draining, a part of the external air will enter the vacuum system through the draining device, causing damage to the internal vacuum environment. At this time, it can only be shut down and the vacuum system is pumped again. Vacuum, the number of draining times is small, and will not cause much interference to the normal production. However, when the number of draining times is large, frequent shutdowns will cause the production cost to rise, and the labor intensity of the operators will also increase. Summary of the invention [0003] The purpose of the present invention is to overcome the problems in the prior art and provide a high-efficiency draining device for a vacuum system, which can realize that when the vacuum tank is draining, external air will not ...

Problems solved by technology

[0002] When the existing vacuum system is draining, a part of the external air often enters the vacuum system from the draining device, causing damage to the internal vacuum environment. Vacuum, the number of liquid discharges is small, and it will not cause too much interference to the normal production. However, when the number of liquid discharges is large, frequent shutdowns will cause an increase in production costs, and at the same time, the labor intensity of operators will also increase.
