RU2232499C1 - Apparatus for automatic dispensing of liquid in portions - Google Patents

Abstract

FIELD: agricultural production, in particular, automatic watering equipment.

SUBSTANCE: apparatus has vessel with inlet and outlet openings, valve arranged in seat above outlet opening and fitted with stem, and float fixed on stem. Cavity with additional seat is positioned under valve seat, said additional seat being axially aligned with main seat and disposed for overlapping both openings by means of single valve. Said cavity is connected through tubular channel with vessel space above float. Rigid plates are joined to one another and placed inside rubber valve in its upper and lower ends.

EFFECT: simplified construction, reduced metal usage and increased efficiency of automatic watering apparatus.

Description

The invention relates to agricultural production, and more specifically to devices for automation of irrigation.

An analogue of the device is a tank with automatic water discharge. However, the presence of two nodes of the valve seal and the elastic disk in it make the operation of the device less reliable during slow filling of water, and the need for accurate mutual alignment of the tank, cylindrical pipe and other elements determines the stringent requirements for the design of the tank [1].

The closest in technical essence to the proposed is a device for automatic portioned dispensing of liquid, containing a container with inlet and outlet openings, located in the saddle above the outlet, a valve with a stem and a float fixed to the rod.

The disadvantage of this device is cumbersome and, as a result, a large material consumption [2].

The technical result from the use of the claimed invention is to simplify the design and reduce material consumption.

The technical result is achieved in that a device for automatic portioned dispensing of liquid, containing a container with inlet and outlet openings, a valve with a stem located in the seat above the outlet, and a float fixed to the rod, a valve under the valve seat with an additional seat located coaxially with the main and the possibility of blocking both outlet openings with one valve, while the subvalve chamber is connected by a tubular channel to the superfusible space of the tank. In addition, inside the rubber valve at its upper and lower ends there are fixed plates connected to each other by a rod.

The drawing shows the proposed device for automatic portioned delivery of liquid.

The device consists of a tank 1, which is gradually filled with liquid from the supply pipe 2 with an adjustable valve 3. To release the liquid from the tank 1, a rubber valve 4 is used, which sits with its upper end on the seat 5. Under the seat 5 of the valve 4, a valve valve 9 with an additional seat 10 is installed located coaxially with the main one and the possibility of overlapping both outlet openings with one valve 4. The subvalvular chamber 9 is connected by a tubular channel 11 to the superfusible space of the container 1. Inside the rubber valve 4 in its upper and lower it ends mounted rigid plates 12 interconnected by a rod 13. The valve 4 is rigidly connected to a rod 6, which can move vertically under the influence of a float mounted on its guide 7. As for the rod holder 6 is used with the sleeve 8.

The proposed device operates as follows.

During the filling of the container 1 from the supply pipe 2 with an adjustable valve 3, the stem 6 is in the lower position and the rubber valve 4 closes both outlet openings of the seats 5, 10. As the filling level, the liquid level in the container 1 gradually rises to the height of the tubular channel 11, and the liquid begins to flow through the tubular channel 11 into the subvalvular chamber 9. When this chamber is filled under the influence of water pressure in the tubular channel 11, the liquid exerts pressure on the walls of the valve 4 and, together with the lifting force of the float 7, pushes out Apan from the main 5 and an additional 10 saddles, and a float 7 pops up. The height of the float 7 is limited by the height of the stem 6. The stem 6 carries the valve 4. The condition for lifting the valve 4 is to exceed the height of the tubular channel 11 above the stem 6 together with the float 7, providing the required pressure force for lifting the valve 4 from under the valve chamber 9. Begins discharge of liquid.

As the liquid exits the tank 1 to the upper base of the float 7 in a raised state, the float 7, and with it the valve 4 connected to the stem 6, gradually fall down. And when lowering valve 4 to the level of the main seat, the valve is sucked to the main 5 and an additional 10 seats, while a small amount of liquid remains in the tank. For a better fit of the valve to the outlet holes, inside the rubber valve in its upper and lower ends are installed rigid plates 12, interconnected by a rod 13.

In the future, the process is repeated. The repetition period depends on the adjustment of the crane 3.

Thus, the proposed device allows you to simplify the design by eliminating one float and locking mechanism, shortening the rod and reduce material consumption.
