Description

The utility model relates to drinking water supply, in particular to nozzles for saving tap water, and is intended to regulate the flow of tap water during the operation of valves.

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 baffle 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 baffle and placed under it [RF Patent No. 1813853].

The design of this nozzle provides a portioned supply of water, but with its help it is not provided to carry out stepwise, fixed flow control depending on the required operating mode. In addition, to open the tap with this nozzle, a large force is required to press the rod about 6-8 kg, due to the pressure drop of the water acting on the valve.

A device for saving tap water (RF patent No. 2117114) is also known, comprising a housing with inlet and outlet openings and a horizontal partition, a metal rod with a retainer passed through the horizontal partition and the outlet, the horizontal partition is made with openings, the rod retainer is made in the form of a plate with a cylindrical recess, the lower part in contact through a rubber gasket with a cylindrical protrusion of the outlet of the housing. The housing is equipped with a fixture for fixing the rod for a continuous flow of water.

The disadvantages of this device are the spraying of water from the impact of the jet on the installed retainer, the complexity of the design, the lack of step-by-step adjustment of the water flow, as well as the absence of modes, both small and large water flow, and therefore it is impossible to regulate the water flow in a wide range water use regimes.

Closest to the claimed is a faucet nozzle for saving tap water [RF patent 2234630] The faucet nozzle contains a housing with an outlet, a housing cover with screws for attaching to the housing, a rubber ring gasket for sealing between the housing and the cover, a clamp with screws for mounting the clamp to the housing cover, a rubber ring gasket for sealing between the outlet pipe of the mixer and the housing cover, a piston mounted in the housing. Symmetrically located tides are made inside the case. To increase the flow of water in the tides, vertical grooves are made. The lower part of the housing, having an outlet in the form of an inverted truncated cone, is a fitting for the possible installation of a hose. A rod is passed through the outlet of the housing. The lower part of the rod also has a conical shape, and the upper part has the shape of a cylinder with cuts on the sides to move between the tides of the body, which simultaneously serve as guides. Grooves are made in the upper part of the stem to increase the flow of water. The housing cover is fastened to the casing with four screws. The inner part of the housing cover has a cylindrical shape for installation of the outlet pipe of the mixer. A rubber ring gasket is installed between the outlet pipe of the mixer and the housing cover.

The device provides a continuous supply of water through the use of the piston configuration and the tides of the lower part of the housing, with ease of installation of the device in home and industrial conditions without reconstruction of the mixers, ensuring the supply and shutoff of water without the use of rubber seals.

However, this nozzle does not provide step-by-step regulation of water flow in a wide range of water use modes: there are no continuous water supply modes at low and high flows, there is no possibility of quick removal of the nozzle to ensure maximum water consumption. Raising the piston up is difficult due to its developed cross section. In addition, the design is complex, unreliable in operation. Precise adjustment of the piston is required in the lower position, 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 stepwise controlling its flow rate 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 for a faucet containing a housing with an outlet, a rod passed through an outlet having a lower conical part, an upper cylindrical part and means for fastening to a water tap, according to a utility model, are made on the lower conical part of the rod cuts on the sides, the upper cylindrical part of the rod acts as a valve and rests on a saddle made in the lower part of the body, and holes are made in it that connect the upper and lower cavity to Busan, wherein the housing has a lower edge of the seat, for locking the rod in the uppermost position.

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 execution of sections on the sides on the lower conical part of the stem forms a height-variable cross-sectional area and, together with the profile of the outlet opening of the body, forms a variable-height outlet cross-section of the nozzle, which allows you to adjust the water flow depending on the height of the stem during portioned water consumption.

Changing the height of the rod, change the flow rate of the required portion of water, which saves water consumption, for example, when washing the face, and ease of use with different modes of water consumption.

In addition, the presence of a gap between the stem and the housing, determined by the slices on the sides of the conical part of the stem, simplifies the design of the nozzle and does not require special adjustment of the stem. 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 remains with the rubber seals available in the water tap, since the nozzle is used without reconstruction of the water tap.

An edge located in the housing below the saddle fixes the position of the rod in the upper extreme position when it is rotated around the axis, providing water savings and ease of use in the mode of average water supply, for example, when rinsing dishes. In this position, the nozzle outlet is constantly maximally open for the required time.

The implementation of through holes in the upper cylindrical part of the rod connecting the upper and lower cavity of the body balances the effect of water pressure on the cylindrical part, reduces the force required to move the rod up and provides, together with the gap between the rod and the body, the minimum continuous flow of water through the nozzle within 5 -10% of the maximum water consumption required, for example, for soaping hands, etc.)

The implementation of the means for attaching the nozzle to the faucet in the form of a quick-detachable threaded connection (for example, with multiple threads) or 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, ensuring the most convenient to use with large water consumption.

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

The device is illustrated by the following drawings:

Fig.7 - shows the nozzle with a bayonet connection.

The nozzle for a faucet includes a housing 1 with an outlet 2 and a rod 3, passed through the outlet 2 (figure 1). The means for attaching to a faucet includes a union nut 4 with a sealing ring 6 and fixation elements for connecting to a pipe of the faucet, which is shown in dashed line in the drawing. The means for attaching to the water tap is made in the form of a threaded connection, for which a thread 5 is made on the inner surface of the union nut 4 and the upper outer surface of the housing 1, which is an element of rigid fixation.

The rod 3 has a lower conical part 7, the upper part 8 in the form of a cylinder. In the lower conical part 7 of the rod 3, cuts 9 are made on the sides, which together with the outlet 2 form a gap 10. In the upper cylindrical part 8 of the rod 3, pressure-balancing holes 11 and 12 are made, connecting the upper and lower cavities 13 and 14 of the housing 1, respectively. The gap 10 together with the holes 11 and 12 provides a minimum flow rate. The upper cylindrical part 8 of the rod 3 rests on the saddle 15, made in the lower part of the housing 1. In the housing 1 below the saddle 15 there is an edge 16, for fixing the rod 3 in the extreme upper position. At the lower end of the rod 3, a ball 17 can be fixed, which reduces the specific force exerted on the arm.

Means for attaching to a water tap can be made in the form of a bayonet connection (Fig.7). In this case, curly grooves 18 are made on the union nut 4, allowing axial and rotational movement of the pins 19 mounted on the outer surface of the housing 1. The grooves 18 and pins 19 are elements of rigid fixation.

The device operates as follows.

The nozzle is installed on a water tap. For this, the union nut 4 is put on the nozzle of the water tap and, rotating the housing 1 along the thread 5, provide a rigid connection with the sealing ring 6.

When the bayonet connection, the union nut 4 is also put on the nozzle of the water tap, move the housing 1 first up, and then turn it until it engages. In this case, the pins 19, move along the figured grooves 18, provide a rigid connection with the sealing ring 6.

When opening the water tap, water enters its nozzle (shown in dashed line in the drawing) and from it into the upper cavity 13 of the nozzle body 1. Through the holes 11 and 12, water enters the lower cavity 14 of the housing 1, from where it goes out through the gap 10 and the outlet 2, creating a minimum water consumption mode of 5-10% of the maximum, since the area of the holes 11 and 12 is much smaller than the area of the water supply pipe crane.

When the rod 3 moves upward, the cylindrical part 8 rises above the seat 15, the lower conical part 7 also moves upward, increasing the gap between the conical part 7 and the housing 1. At the same time, the area of the outlet 2 increases, the water flow increases depending on the height of the rod 3 ( figure 2). When lowering the rod 3 down, this gap decreases, the cylindrical part 8 sits on the saddle 15, thereby blocking the flow of water. Once again, a water use regime begins with a minimum water consumption. Thus, an economical portioned water supply is provided. The movement of the rod 3 up and down and changing the gap between the housing 1 and the rod 3 helps to remove grains of sand, dirt, rust from the nozzle, ensuring the reliability of its operation.

To obtain a mode of average continuous water consumption, the rod 3 is raised upward, turning around its axis, and fixed on the edge 16 (figure 3).

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 done by disconnecting the threaded connection. At the same time, for quick disconnection, the thread 5 can be multi-start.

Removing the nozzle during bayonet connection is carried out by turning the housing 1 and its subsequent axial movement downward relative to the union nut 4.

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.
