Description

The invention relates to the field of sanitary fittings controlled by a float, and can be used for drain tanks with a lower water supply.

In the prior art, filling fittings of a drain tank with a lateral water supply are provided, comprising a drain pipe with a guide along which the float moves, and an inlet valve body mounted on the drain pipe with a pressure channel connected to the water supply pipe and a drain channel connected to the drain cavity pipes, between which a membrane is installed, interacting through the membrane body with the beam, which is connected via a rod to the float (see patent ES 2190351, class E03D 1/00, publ. July 16, 2003). A disadvantage of the known device is the impossibility of its use in drain tanks with a lower water supply.

The objective of the utility model is to eliminate this drawback. The technical result consists in providing the possibility of using filling fittings in drain tanks with a lower water supply. The problem is solved, and the technical result is achieved by the fact that in the filling fixture with a bottom water supply containing a drain pipe with a guide along which the float moves, and an intake valve body mounted on the drain pipe with a pressure channel connected to the water supply pipe and a drain a channel connected to the cavity of the drain pipe, between which a membrane is installed, interacting through the membrane housing with the beam, which is connected through a rod to the float, the inlet valve body, and also romyslo, the membrane body and the membrane itself secured to the valve body by means of clamping screws and located under the drain pipe. Preferably, a filter with a labyrinth-type hydraulic throttle is installed in the water supply pipe. The pressure channel is preferably conical and the drain channel is divided by a divider into two rectangular sections perpendicular to its axis. The inlet valve housing is preferably provided with a protection ring, which makes it possible to quench the kinetic energy of the incoming water. The inlet valve body, diaphragm body, rocker arm, rod and nut are preferably made of polyacetal, the membrane is made of rubber, and the float, drain pipe and filter are made of polypropylene.

In FIG. 1 shows the element-wise proposed fittings; in FIG. 2 - sectional inlet valve.

Filling fittings - a device that, after emptying the drain tank, automatically fills it with a certain amount of water and hermetically closes. The proposed fittings are designed for installation in a drain tank with a bottom water supply and is equipped with an inlet valve with a float type control device.

The inlet valve of the filling valve consists of a valve body 1 with a pressure channel 1a and drain 16 channels, a membrane 2, its fixing rod 3, a membrane body 4 with a nozzle 4a and a protective ring 5, which are fixed to the valve body 1 of the clamping nut 6. Control elements for the inlet valves are a float 7, for which the guide during vertical movement is a drain pipe 8 fixed to the valve body 1, a rod 9 and a rocker 10 with a pusher 11, connected by a rod 9 with a float 7. The intake valve body 1, as well as the rocker 10, the membrane body 4 and the membrane 2 itself are located under the drain pipe 8.

The membrane 2 is made in a plate shape and has a large hole that serves to fix on the stem 3, and a small hole for water passage. Two flats are made on the conical part of the stem 3, and a groove is made on the end connecting them to the inlet fitting of a c-shaped section. To fix the membrane 2, a rod with hooks is provided on the rod 3. The membrane housing 4 is made in the form of a cover with a cone in which the nozzle 4a is located. To center the rod 3, an annular protrusion is made inside the membrane housing 4. On the side surface of the membrane body 4 there is also a protrusion for proper installation in the valve body 1. On the outer surface of the membrane body 4, there is a fork bracket, in the holes in which the cylindrical bosses of the rocker arm are mounted 10. A fork is inserted into the rocker arm 10, into which the rod 9 is latched. The protective ring 5 extinguishes the jet of water flowing from the valve body 1, directing it to the bottom of the drain tank through a narrow slot, thereby eliminating splashing and reducing noise. Round clamping nut 5 is provided with protruding ribs to facilitate tightening.

The position of the float 7 is regulated by rotation of the rod 9 in the nut made on it in the form of one incomplete turn. The rod 9 is a screw with a flange and a head, between which the fork of the rocker arm is mounted 10. On the outer surface of the drain pipe 8 a longitudinal guide is made to center the float 6.

The inlet valve through the pressure channel 1A communicates with the water supply pipe in which the filter 12 is installed. The filter 12 purifies the water from suspended particles by passing it through openings of 0.5 × 0.5 mm. To reduce the flow rate, it is equipped with a labyrinth-type hydraulic throttle, which makes the filling reinforcement low noise. By means of the indicated water supply pipe, the filling fittings are fastened in the tank with a hex nut 13 with a flange that abuts when tightening against the tank wall, through a gasket 14 made in the form of a conical sleeve with a number of elastic ring ribs.

To quench water energy and reduce noise, the pressure channel 1a is narrow and conical, and the drain channel 16 is divided by a divider into two narrow rectangular channels perpendicular to its axis, causing the water stream to change direction and lose kinetic energy.

As the material of the valve body 1, the membrane body 4, rod 3, rocker arm 10, rod 9 and nuts 6, 13, polyacetal is used that can withstand high tensile and bending loads. The membrane 2 is made of rubber, and the gasket 14 of the plasma. The float 7, the protective ring 5, the drain pipe 8 and the filter 12 are made of polypropylene.

Filling reinforcement works as follows.

If the drain tank is empty, under pressure of water from the line, the membrane 2 is squeezed, freeing the passage of passage from the pressure channel 1a to drain 16, from where it, partially stopped by the protective ring 5, enters the drain tank. As the tank is filling, the float 7 rises along the drain pipe 8 up to the upper point at which it acts through the nozzle 9 and rocker 10 on the nozzle 4a of the membrane body 4, moving the membrane 2 to the closed position. After emptying the drain tank, the float 7 again lowers down, releasing the membrane 2.

The proposed utility model allows the device to be used in drain tanks with a lower water supply.
