SU141815A1 - Faucet for flushing toilets of fecal fluids - Google Patents

Description

Known flush taps for flushing in the toilet of fecal fluids, in the body cavity of which a cylinder is mounted. Inside the cylinder there is a piston and a rod, on one side of which a stop valve is fixed, and on the other outer side a handle is fixed. When you press the handle, the mixing rod drives the piston and opens the valve, ensuring water flows from the plumbing to the toilet. After stopping the pressure on the knob, the shut-off valve is closed by the pressure of water, the piston is brought to its original position and the flow of water to the toilet is stopped.

The disadvantages of the known flush valves are some of the complexity of their devices and hydraulic shocks that occur in a water supply network during operation. A crane made according to the invention is free from these disadvantages. The essence of the invention is that the valve is provided with a pressure regulator with a disk valve, and there is a gap between the piston and the walls of the housing cavity with openings for water pasture.

FIG. 1 shows the proposed crane; in fig. 2 is a section along A-A; FIG. one.

A crane moles from the housing 1, the piston 2, the stem 3, the valve 4 with the gasket 5, the handle 6 and the pressure regulator 7 with the disk valve. There is a gap 10 between the piston 2 and the walls of the housing cavity / with the openings 8 for supplying water from the water mains connected to the pipe 9.

The valve 4 start water is pressed to the saddle 11 by the pressure of the water in the water supply network. For pressing valve 4 from the seat 11, when actuating the flush valve, handle 6 is used, when pressed, rod 3 senses the pressing force increased in relation to the gear ratio (ratio of handle length 6 to plate diameter; 141815-- 2 rod 5 ). At the same time, simultaneously with the rod 3 and the valve 4, the noptoeTft2, moving freely, with a small gap, moves | in the cylinder, p jnyca 1. The water entering the washout simultaneously fills the chamber, Gassed by the removed piston 2 and the housing 7, through the hole. S i opnycaG | on pre5; rasch1p1i, „press the handle 6, valve 4 will not close, but the valve until the water accumulated between the piston 2 and the housing // is pressed by the water pressure on the valve 4 through the piston gap 10 and holes 8 in the housing / in the flush pipe 12.

Due to this hydraulic damper, though not very long in time (about a fraction of a second or 1-2 seconds), a slowdown in closing the valve will completely eliminate the hydraulic shock in the network.

The proposed crane is designed for toilet bowls of residential buildings, toilet bowls and floor bowls of public and industrial buildings.

The pressure regulator 7 serves instead of the non-ferrous alloy shut-off valves used, which provides greater compactness and savings of the non-ferrous metal.

The change of the gaskets 5 is carried out quite simply, since turning the housing 1 counterclockwise removes the entire core - this is also an advantage of the proposed design.

Subject invention

A flush valve in the toilet of fecal fluids, in the body cavity of which a piston and valve are opened, opened by means of a handle and a stem and closed with water pressure, characterized in that, in order to simplify the device as a whole and to prevent water hammer in the water supply network, It is equipped with a pressure regulator with a disc valve, and between the piston and the walls of the housing cavity, which has an opening through which the aode enters, creating a gap.
