Abstract

The invention relates to reinforcement and can be applied to control the flow of hot and cold water. The aim of the invention is to increase the reliability of adjusting the maximum sealing force of the mixer tap seat. On housing 9 of each valve head, screw 19 is attached to a nozzle ring 20 provided with a stop 21 for engaging one of the radial protrusions located on plate 15. A square hole 24 is made in plate 15 to mate with a faceted tail, and the invention relates to reinforcement and can be used to control the supply of hot and cold water. The aim of the invention is to increase the reliability of adjusting the maximum sealing force of the mixer tap seat. On fLg.1 shows a faucet mixer, front view; figure 2 - tap mixer, a top view of fig.Z - section aa in figure 1; figure 4 - section bb on League .3. com 12. The radial protrusions of the plate are shifted relative to the axis of symmetry of the hole for a faceted shank, tpndel at angles that are multiples of half the increment of adjustment increments. When the flywheels 14 of the valve heads are rotated, the valves 1t rise and allow the flows of the mixed liquids into the body 1, and from there into one of the discharge pipes.

Description

the protrusion 17 and installed in the holes of the flywheel 14 with the possibility of installation rotation to align the protrusion 17 with one of the marks 18 on the body 1 of the mixer valve.

On housing 9 of each valve head 7 or 8 is fixed with a screw 19 a nozzle ring 20 provided with an abutment 21 for engaging one of the radial protrusions 22 and 23 located on the plate 15. A square hole 24 is made in the plate 15 to mate with a faceted square shank 12. The protrusions 22, 23 are offset from the 0-0 axis of symmetry of the hole 24 to the angles С /, and УЈ, multiples of half the increment step of the adjustment, defined by the expression

n step of adjustment; the number of corners of a polygonal plate hole is the number of radial protrusions of the plate.

Each valve 11 is provided with a seal 25 with the possibility of contact with the seat 26 of the housing 1.

For example, for a square hole, by swapping and flipping the plate, the spindle rotation is evenly adjusted with a resolution of 22.5 °. At the same time, the angles (х% and Equal are 11.25 and З3, respectively, 75 °.

Crane-mixer works as follows.

When the flywheels 14 of the valve heads 7 and 8 rotate, the valves 11 rise and allow the flows of the mixed liquids into the body 1, and from there into one of the discharge pipelines 5

or 6. When opening each of the 45-spins, the faceted spindle shank at the corners,

divided by 10 is shifted in axial direction by multiples of half the step increment

together with the plate 15, therefore, the adjustment.

the other (non-working) radial protrusion freely passes over the stop 21, allowing the spindle 10 to rotate several turns.

When closing the mixer, each of the spindles 10 is rotated to the position of the contact of the radial protrusion 22 or 23 with the stop 21, not paying attention to the intensity of the jet flowing out of the mixer tap. In this case, the degree of closure is also visually monitored by combining the angular projections 17 with the marks 18 on the housing 1.

Claims (1)

In the case of wear of the seal 25 of the valve 11 (determined by fluid leakage), remove the flywheel 14, the plate 15 and turn the spindle U until the leakage of the fluid stops. Then, the plate 15 is placed in the position of contacting one of the protrusions 22, 23 with the abutment 21. After that, the flywheel 14 is fixed and the stopper 16 is installed in it. A mixer tap containing valve heads that are hydraulically interconnected, in the case of each of which there is a threaded spindle with a shut-off valve and a restrictor for its movement, made in the form of a plate with a central hole covering the spindle stem, and radial protrusions arranged to cooperate with a stop mounted on the valve head body, characterized in that, in order to increase the reliability of adjusting the maximum sealing force of the saddle, the spindle stem is made faceted and the radial protrusions of the plate are shifted u Phie.1 Fig z Aa 20 21 Hi a U 26 3 22 12
