Water leakage-proof and oil leakage-proof switch

Abstract

The invention provides a water leakage-proof and oil leakage-proof switch. The water leakage-proof and oil leakage-proof switch comprises a liquid inlet, a first water blocking structure, a buffer tube, a second water blocking structure and a liquid outlet which are connected in series in sequence; the buffer tube further communicates with an air pump connecting tube; the air pump connecting tubeis provided with an air valve; and the air pump connecting tube is used for externally connecting a high-pressure air pump. By using the two stages of water blocking structures, the tightness of the switch is better, and leakage is not easy to generate; meanwhile, the air pump connecting tube is added between the two stages of water blocking structures, the air pump connecting tube is provided with the air valve, and the air pump connecting tube is used for externally connecting the high-pressure air pump, so that excess liquid in a pipeline can be returned or discharged through the high-pressure air pump after oil discharge, and the phenomenon that liquid is accumulated in the pipeline to generate corrosion or other losses; and the liquid inlet, the first water blocking structure, the buffer tube, the second water blocking structure and the liquid outlet are each coated with an anticorrosive coating, so that the service life is further prolonged.

Description

technical field [0001] The invention relates to a water and oil leakage prevention switch. Background technique [0002] Electric constant temperature oil bath is widely used in distillation, drying, concentration and impregnation of chemicals or biological products. It is an ideal and necessary tool for laboratories in colleges and universities, environmental protection, scientific research, health, epidemic prevention, petroleum, metallurgy, chemical industry, medical and other units. [0003] In order to facilitate the discharge of the oil in the pot body, a switch is generally arranged at the bottom of the oil bath pot to communicate with the oil outlet of the high-temperature oil pump. Oil leakage occurs, so it is urgent to design a switch that prevents water leakage and oil leakage, so as to increase the service life of the equipment. Contents of the invention [0004] The object of the present invention is to provide a water and oil leakage prevention switch, whic...
