Description

The utility model relates to the field of production of sanitary equipment, and can also be widely used in the operation of housing and communal services.

The device is an integral part of a set of measures to save water resources and reduce water consumption, as well as electricity and gas, which are directly used to heat water for sanitary purposes.

Currently, due to the high cost of tap water, there is a problem of its economical use by reducing losses during operations such as washing, washing dishes, brushing teeth, shaving, quickly filling the bath, etc. The design of the currently used water taps and mixers does not provide for economical water consumption. Known nozzles for water taps allow for economical water consumption, but have several disadvantages.

Known nozzle for a faucet containing a housing with inlet and outlet openings, a positive buoyancy valve connected to the stem, and a valve seat located across the housing. The nozzle is equipped with a perforated partition installed in the outlet made in the bottom of the housing, and the free end of the rod is passed through the hole of the perforated partition and placed under it (RF patent 1813853 from 06.25.90).

The design of this nozzle provides a portioned supply of water, but with its help it is impossible to carry out smooth control of the flow depending on the required operating mode. In addition, to open the tap with this nozzle, a large effort is required to press the rod, about 6-8 kilograms, due to the pressure drop of the water acting on the valve.

Known nozzle for a faucet containing a housing with an outlet, means for attaching to a faucet, a rod passed through an outlet having a lower conical part and an upper cylindrical part, on the lower conical part of which cuts are made on the sides, in the upper cylindrical part of the rod holes are made connecting the upper and lower cavity of the housing. The upper cylindrical part of the stem rests on a saddle made in the lower part of the housing, while in the housing below the saddle there is an edge for fixing the stem in the upper position (RF patent for PM 102735 from 07/06/2010).

The disadvantages of this device are the complexity of the internal shape of the housing, requiring the use of expensive machine-tool equipment for production, as well as the relatively large effort to bring the nozzle into position, resulting in distortions of the stem movement and travel jam. Precise adjustment of the upper part of the rod in the lower position is required, in which the water is shut off without the use of rubber seals. In case of dirt, rust, the nozzle will constantly leak.

The proposed utility model is based on the task of reducing water losses by smoothly regulating its flow in a wide range of water use modes, reducing the opening force and increasing reliability while simplifying the design.

The problem is solved in that in the nozzle on the tap or mixer for the washbasin, comprising a housing with inlet and outlet openings through which the rod is passed, and means for attaching to a water tap, the stem head is extended above the housing inlet and further installed a gasket that forms with the head a valve held in a closed position by a conical spring interacting along the axis of the stem with a water flow control lever connected by a thread to the lower end of the stem and withdrawn perpendicular to the body wall behind the nozzle body, while the water flow control lever is made L-shaped, and radial grooves are made on the lower surface of the stem head.

In this case, the means for attaching to a water tap can be made in the form of a quick-detachable threaded connection or in the form of a bayonet connection.

The fundamental difference between the utility model and the prototype and analogues is a change in the principle of regulating the valve bore, which changes in proportion to the angle of inclination of the upper cylindrical part of the stem when the valve control lever is pressed.

By changing the angle of the rod, the flow rate of the required portion of water is changed, which saves water consumption, for example, when washing your face, and ease of use with different modes of water consumption. The stepwise regulation of the throughput of the nozzle on the crane is carried out by choosing the ratio of the diameters of the rod and the inlet of the nozzle body. At the same time, the radial grooves available on the lower surface of the cylindrical part of the stem provide an indicative stream of water (minimum flow rate), which shows the operability of the tap and can be used for domestic operations with extremely low water consumption (soaping of hands).

The reliability of the nozzle increases, since the ingress of small specks, dirt, and pieces of rust does not violate the regime of low water flow, the tight shutoff of the water flow at the junction of the nozzle and the tap is ensured by a gasket that simultaneously seals the control valve.

The implementation of the means for attaching the nozzle to the water tap in the form of a quick-detachable threaded connection (for example, with multiple threads) or a bayonet connection provides, when removing the nozzle, the maximum water flow rate (for example, when filling the bath) allows you to quickly remove it without using wrenches, thus ensuring the most convenient to use with large water consumption.

Thus, the claimed utility model provides a reduction in water losses by providing stepwise and continuous regulation of water flow, regulating its flow in a wide range of water use modes, reducing the opening force, improving reliability and ease of use while simplifying the design.

The design of the device is illustrated in FIG. 1 of FIG. 2. In FIG. 1 shows a longitudinal section of a nozzle for a water tap in the minimum constant flow rate of water. In FIG. 2 - a longitudinal section of the nozzle on the tap in the water supply mode.

The nozzle on the tap or mixer for the washbasin consists of a housing 1 with an inlet 2 and an outlet 3 through which a rod 4 is passed. The upper part of the housing 1 contains means for fastening to a water tap, for example, a thread 5. The head 6 of the rod 4 is cylindrical and extended over the inlet 2 of the housing 1 and under it on the housing 1 an additional gasket 7 is installed, which forms with the head 6 a valve held in a closed position by a conical spring 8 interacting along the axis of the rod 4 with the sweat control lever 9 a water eye connected by a thread to the lower end of the rod 4. The water flow control lever 9 is discharged perpendicular to the housing wall behind the housing 1, while the water flow control lever 9 is L-shaped, and radial grooves are made on the lower surface of the head 6 of the stem 4. The decorative tip 10 is attached to the housing 1 by means of a thread and provides an aesthetic appearance of the nozzle on the tap or washbasin faucet. To fix the maximum volume of water flowing out in the tip 10, a window 11 is made in which a lever 9 for controlling the flow of water is brought out.

The means for attaching to a water tap can also be made in the form of a quick-detachable threaded connection or in the form of a bayonet connection, or in the form of a split ring (not shown).

The nozzle on the tap or mixer washbasin is used and works as follows (Fig. 2). The nozzle on the faucet or mixer is screwed with an inlet 2 with a thread 5 on the upper part of the housing 1 into the faucet (mixer) 12, after removing the aerator nets from it. The gasket 7 provides sealing of the created connection. In the initial state, the head 6 of the rod 4 is pressed with the conical spring 8 onto the gasket 7 with its lower surface and an indicative stream of water flows into the outlet 3 (for the model with radial slots on the lower surface of the head 6). In the absence of these slots, the entire flow of water remains blocked. After pressing the lever 9 in the direction of arrow A, the rod 4 deviates from the vertical, the spring 8 is compressed from the side of the lever 9, the head 6 of the rod 4 is lifted by one of its edges, the water begins to move as shown by arrow B and flows from the outlet 3 of the nozzle to the tap. If necessary, aerator grids (not shown) can be installed in the cavity of the tip 10. In the case when it is required that the water flow through the nozzle does not stop, the lever 9 for controlling the water flow after deviation in the direction of arrow A rotates clockwise 10 ° in the window 11 and is fixed from returning to the initial position by the wall of the tip 10. The reverse movement of the lever 9 leads to a complete cessation of the flow of water from the nozzle to the tap.

The fundamental difference between the utility model and the prototype and its analogues is a change in the principle of regulating the nozzle through passage, which changes in proportion to the angle of inclination of the head 6 of the rod 4 when the lever 9 for controlling the flow of water is pressed.

By changing the angle of inclination of the head 6 of the rod 4, the rate of expiration of the required portion of water is changed, which saves water consumption, for example, when washing the face, and ease of use in various modes of water consumption. Stepwise regulation of the throughput of the nozzle on the crane is carried out by choosing the ratio of the diameters of the rod 4 and the inlet 2 of the body 1 of the nozzle. At the same time, radial grooves (not shown) available on the lower surface of the head 6 of the rod 4 provide an indicative stream of water (minimum flow rate), which indicates the operability of the tap and can be used for household operations with extremely low water consumption (hand soaping).

The reliability of the nozzle increases, since the ingress of small specks, dirt, pieces of rust does not violate the mode of low water consumption, the tight shutoff of the water flow at the junction of the nozzle and the tap is provided by a gasket 7, which at the same time provides a seal for the water flow control unit.

The implementation of the means for attaching the nozzle to the water tap in the form of a quick-detachable threaded connection (for example, with multiple threads) or a bayonet connection provides, when removing the nozzle, the maximum water flow rate (for example, when filling the bath) allows you to quickly remove it without using wrenches, thus ensuring the most convenient to use with large water consumption.

If it is necessary to fill large volumes (for example, baths), the nozzle is removed from the nozzle of the water tap and the maximum water consumption mode is set. Removing the nozzle is carried out by disconnecting the threaded connection between the valve 12 and the housing 1 of the nozzle. At the same time, for quick disconnection, the thread 5 can be multi-start.

Thus, the inventive nozzle on a water tap provides economical water consumption in various modes of water consumption, ease of use with reliable operation of the nozzle and does not require reconstruction of a water tap.

The nozzle is manufactured from industrially used materials traditionally used in the production of sanitary products: brass, bronze, aluminum alloys. Decorative coatings are used for the conical spring and the water flow control lever to increase corrosion resistance and give an appearance.
