Abstract

This invention relates to a valve industry, in particular to domestic water systems. The aim of the invention is to improve the reliability of closing the mixer under the conditions of vibration of the volume on which it is installed. The device consists of a cylindrical body 1 with radially arranged inlet nozzles 2 and 3 for cold and hot water and an outflow 5. The mixer valve is made in the form of a piston 6 with a rod 7, on which a spring-loaded sleeve 9 is installed, which interacts with the eccentric 11 of the drive shaft 12 When the drive shaft 12 rotates, the sleeve 9, through the spring 16, transmits the force to the piston 6, which overlaps the outlet nozzle 4. The eccentric 11 thus passes the bottom dead center and stably fixes the piston 10 in the closed position. 4 il.

Description

„

The invention relates to fittings, in particular to domestic water systems.

The aim of the invention is to improve the reliability of closing the mixer under vibration conditions.

FIG. 1 shows a mixer, a general view; in fig. 2 is a section A-A (in Fig. 1; in Fig. 3 is a section B-B in Fig. 1; in Fig. K is a section B-B in Fig. 1 (the position of the eccentric with the transition of the bottom dead center).

The mixer contains a cylindrical body 1 with radially arranged inlet pipes 2 and 3 for cold and hot water and a discharge pipe 4 5 connected to the spout 5. In the case 1 there is a shut-off valve in the form of a piston 6 with JUITOKOM 7. Axial {flow passages 8 are made in piston 6. A sleeve 9 with two annular projections 10 is movably mounted on the rod 7. Between the projections 10 there is an eccentric 11 of the drive shaft 12, on which the limiters 13 and 1 of the extreme positions of the eccentric 11 are placed, and the housing 1 has a stop 15, the interaction with limit stops 13 and And at the extreme positions of the piston 6. The sleeve 9 is tucked in the direction of the washer 16 by the spring 17.

The mixer works as follows.

When the drive shaft 12 rotates, the eccentric 11 transfers the force to one of the projections 10 of the sleeve 9, depending on the direction of rotation. When the eccentric 11 is exposed to the upper slope of the sleeve 9, it rises and through the washer 16 together with the rod 7 raises the piston 6.

blunt into the spout 5. The hot water inlet nozzle 3 thus remains blocked by the side surface of the piston 6.

Upon further rotation of the shaft 12, the hot water pipe 3 opens and mixed water flows into the spout 5. When the shaft rotates up to the stop 15, the eccentric 11 moves to the dead center, completely blocking the cold water inlet 2. When the hall rotates in the opposite direction against the stop, the eccentric 11 passes the dead point, and the spring 17 is compressed by the necessary force through the lower ledge 0, the eccentric 11 presses the rotation stop 13 to the stop 15, simultaneously blocking the piston b with the spout 5.
