Abstract

The utility model discloses a vacuum system which comprises a vacuum tank body and a vacuum pump. A three-way valve is arranged between the vacuum tank body and the vacuum pump, and two ends of the three-way valve are respectively connected with the vacuum tank body and the vacuum pump. The other end of the three-way valve is connected with a recovery tank, and control valves are arranged on pipelines connected with the three-way valve, the vacuum tank body and a recovery tank body. The vacuum system solves the problem that just at the moment when the vacuum pump in the vacuum system stops working, vacuum oil in the vacuum pump flows back. The structure is designed to be reasonable, due to the reasonable distribution of the three-way valve and the control valves, the vacuum system is convenient and easy to operate and low in cost.

Description

A kind of vacuum system
Technical field
The utility model relates to the vacuum equipment technical field, specifically belongs to a kind of vacuum system.
Background technique
Existing vacuum measurement equipment is directly communicated with vacuum tank by vacuum pump, and is in a flash out of service at vacuum pump, has negative pressure in the vacuum tank, causes the vacuum oil in the vacuum pump to reflux, and goes down for a long time, just can have impurity in the vacuum tank, affects degree of vacuum.What also have has designed anti-backflow at the pump housing, but cost is very high.
The model utility content
The purpose of this utility model has provided a kind of vacuum system, has solved the vacuum system intermediate pump in a flash out of service, the problem that the vacuum oil in the vacuum pump refluxes, project organization is reasonable, by three-way valve and control valve rational deployment, easy to operate simple, cost is low.
The technical solution adopted in the utility model is as follows:
A kind of vacuum system, comprise vacuum tank and vacuum pump, between described vacuum tank and the vacuum pump three-way valve is set, the three-way valve two ends are connected with vacuum pump with vacuum tank respectively, the three-way valve the other end connects recycling can, is provided with control valve at three-way valve and vacuum tank with recovery tank body connecting tube.
Described three-way valve and pipeline junction are provided with seal ring.
Described three-way valve is the glass three-way valve.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model is by three-way valve and control valve rational deployment, effectively prevent at the vacuum system intermediate pump in a flash out of service, the problem that the vacuum oil in the vacuum pump refluxes, easy to operate simple, cost is low.
