Description

In MANY pressure hydraulic systems, fluid pressure is created by using compressed gas or air. For this, a gas cushion is created in the pressurized vial, squeezing the liquid through the intake manifold of the fed system. As the liquid flows, gas begins to fill the pipelines of the system, which in most cases is unacceptable. In such cases, gas cut-offs are used for the displacement vessel, the known constructions of which usually contain a closed chamber in which there is a float suspended on a swing arm pivotally connected to the air vent valve.

The proposed gas cut-off for the displacement vessel differs from the known ones in that it, in order to exclude the possibility of gas breakthrough into the fed system, uses an electrical switch that interacts with the valve and turns off the latch electromagnet of the spring-loaded valve that turns off the gas supply to the displacement vessel as the liquid is consumed .

FIG. 1 shows cxe.ia of the proposed gas cutter; in fig. 2 is a longitudinal section of the closed chamber of the gas cutter; in fig. 3 is a longitudinal section of a gas cutoff valve.

The gas cut-off valve (Fig. 1) for the displacement vessel is made using a closed chamber / and electric switch 2. In the closed chamber / there is a float 3 suspended on the swinging lever 4, connected to the air vent valve 5.

The switch 2 interacts with the valve 5 and turns off the electromagnet 6 of the latch 7 of the spring-loaded valve 8, which turns off the gas supply to the pressure vessel 9 after the liquid is exhausted from it.

Works gas cut-off as follows.

The liquid under the action of gas in the pressure vessel 9 fills the chamber / and the fed system 10. In this case, the float 3 takes the upper position, the latch 7 of the spring-loaded valve 8 also takes

the upper position (held by the electromagnet 6), ensuring the passage of gas to the mirror of the fluid in the displacer vessel 9. In the event of an excessive wake1 | The fasa in the chamber / it displaces the liquid and the float 3 is lowered, allowing the excess air to escape through the valve 5 and the pipe // to the atmosphere.

When a liquid is exhausted, gas in a large amount fills chamber /, which causes not only lowering of the float 3 and opening of valve 5 to release gas to the atmosphere, but also triggering of electrical switch 2. The latter turns off electromagnet 6, latch 7 reverses valve 8 under the action of its spring J2 gas access to the pressure vessel I and, consequently, its breakthrough through the chamber / into the fed system 10. When filling the system with liquid, use the lever J3 to pull the latch 7 to the upper position to allow the gas to pass into the vessel 9.

The proposed gas cut-off for the pressure vessel was found acceptable for use in food processing.

Subject invention

A gas cutter for a pressure vessel with the use of a closed chamber, of which there is a float, located on the rocker arm, pivotally connected to the air vent valve, in order to prevent the possibility of gas breakthrough into the feed the system, an electrical switch is used, which interacts with the valve and turns off the electromagnet of the latch of a spring-loaded valve, which turns off the gas supply to the displacing vessel, when the liquid is consumed from it.
