Description

The invention relates to auxiliary devices for a fluid supply means, for example, a clean liquid tap or mixer with a clean liquid supply line, which are preferably used in liquid purification systems, for example reverse osmosis liquid purification systems.

The prior art adapter for means of fluid supply according to the patent US 4,454,891 [MCP F16K 24/00, publ. 06/19/1984], which consists of the upper and lower parts, the upper part being made in the form of a plug with a depression of a spherical shape, and the lower part is made with a tube for an upward flow of liquid and a tube for a downward flow of liquid. In this case, both tubes have straight and curved sections. The diameter of the tube for upward fluid flow is less than the diameter of the tube for downward fluid flow. A straight section of the tube for upward fluid flow is inserted into a straight section of the tube for downward fluid flow. The junction of the tubes is sealed. The height of the tube for the downward flow of fluid exceeds the height of the tube for the upward flow of fluid. The height of the recess of the upper part exceeds the height of the tube for upward fluid flow. The upper part is inserted into the tube for a downward flow of fluid. Since the height of the tube for the upward fluid flow is less than the height of the recess of a spherical shape, the outlet of the tube for the upward fluid flow leaving the recess remains open for the passage of fluid. Thus, when connecting the upper and lower parts in the upper part of the lower part, a closed cavity is formed around the open outlet of the tube for an upward flow of liquid.

The air gap is made in the upper part and consists of four through holes, separated by thin walls.

The specified adapter provides the following liquid flow: the liquid enters the tube for an upward fluid flow and from an open outlet in communication with the recess flows through a closed cavity formed in the upper part of the lower part around the open outlet of the tube for an upward fluid flow into a tube for a downward fluid flow and through the open end of the tube for the downward flow of fluid flows from the adapter.

The main disadvantage of the above-described adapter for the fluid supply means is that since the tube for upward fluid flows into a closed cavity formed in the upper part of the lower part around the open outlet of the tube for upward fluid, the flow of fluid flowing from the open outlet of the tube for upward flow fluid will be turbulent. In addition, both tubes of the lower part are bent to the point of their connection. Both of the factors described above lead to an uneven flow of liquid, which creates an increased noise level during the operation of the adapter, in addition, due to the uneven flow of fluid at the junction of the two tubes, a region of fluid stagnation arises, which is a source of potential danger to the consumer due to the possibility of development they have a source of microbiological contamination. Also, due to wear and tear of materials, there is the possibility of depressurization of the joints and leaks of contaminated liquids.

These disadvantages are partially eliminated due to the transition to straight tubes in the adapters for the fluid supply means.

The prior art adapter for fluid supply means according to the patent US 3,967,638 [MCP F16K 24/00, publ. 06/06/1976]. The adapter with a single channel for the passage of fluid consists of a housing and two tubes of different diameters. A tube with a smaller diameter is inserted into a tube with a larger diameter. The tube with a smaller diameter is made with a U-shaped bend located close to the junction with the tube with a larger diameter. A single channel for the passage of fluid formed by connecting two tubes has three sections: an ascending section with a smaller cross section, formed by a straight section of a tube with a smaller diameter, an upper section with a bend of a U-shape, formed by a section with a bend of a U-shaped tube of a smaller diameter and a descending section with a large cross section formed by a tube with a large diameter. Moreover, a tube with a smaller diameter simultaneously performs the function of a throttling means.

The specified adapter provides the following liquid flow: the liquid enters the ascending part of the single channel for the passage of liquid, passes the upper part with a bend of a U-shape and passes at a reduced speed the descending part of the single channel for the passage of liquid.

The adapter with a single channel for the passage of fluid according to the patent US 8,733,386 [MKP E03C 1/10, publ. 05.27.2014] consists of three main parts: the upper, lower and hollow tubes with a U-shaped bend, which are inserted into the housing. Two vertical hollow tubes are made in the upper part, in one of which there is an air gap made in the form of an opening. One end of the hollow tube with a U-shaped bend is inserted from above into one of the hollow tubes of the upper part, the second end of the hollow tube with a U-shaped bend is inserted from above into the second hollow tube of the upper part. In the lower part, two hollow tubes are made with a length exceeding the length of the hollow tubes of the upper part, but with a diameter smaller than the diameter of the hollow tubes of the upper part. The diameter of the hollow tube with a U-shaped bend is smaller than the diameter of the hollow tubes of the lower part. A hollow tube with a U-shaped bend is a means of throttling.

A single channel for the passage of fluid is formed by connecting the upper part with the hollow tube inserted into it with a U-shaped bend, and the lower parts. The upper ends of the tubes of the lower part are inserted into the lower ends of the tubes of the upper part. Thus, a single channel for the passage of fluid with a U-shaped bend is formed, consisting of an upward longitudinal section, a section with a U-shaped bend and a downward longitudinal section.

The specified adapter provides the following fluid flow: the fluid enters the upstream portion of the single channel for the passage of fluid, passes at an increased speed the section with a bend of a U-shape, and the downstream portion of the single channel for the passage of fluid leaves the adapter.

The main disadvantage of the above adapters for patents US 3,967,638 [INC F16K 24/00, publ. 06/06/1976] and US 8,733,386 [MKP E03C 1/10, publ. 05.27.2014] is that the ascending and descending longitudinal sections of a single channel for the passage of fluid are made of various materials, and the adapters themselves consist of more than two parts. This leads to the fact that the oscillatory movements of the parts relative to each other that occur when the fluid flows through the adapter are a source of noise and vibration.

The prior art adapter for means of fluid supply according to the patent US 5,865,209 [MCP E03C 1/10, publ. 02.02.1999], selected by us as the closest analogue.

The adapter for fluid supply with a single channel for the passage of fluid, consists of an upper part provided with a connecting element with a portion of a single channel located in it, and a lower part made with ascending and descending through longitudinal sections of a single channel, a throttling means and an air gap, a single channel portion of the upper part is formed when the connecting element of the upper part is connected to the lower part. The connecting element of the upper part is made in the form of two C-shaped protrusions located symmetrically to each other on the lower surface of the upper part adjacent to the upper surface of the lower part. The diameter of the C-shaped protrusions coincides with the diameter of the outlet of the ascending and the entrance of the descending through longitudinal sections located on the outer upper surface of the lower part of the adapter. When connecting the upper and lower parts, one of the C-shaped protrusions symmetrical to each other is connected to the outlet of the ascending longitudinal through section, the second C-shaped protrusion is connected to the inlet of the descending longitudinal through section. Thus, when connecting the upper and lower parts of the adapter, a single channel is formed for the passage of fluid. The formed channel section of the upper part has a rectangular shape.

The throttling means is a separate part and is made in the form of a focusing ring, with a hole located in the center for the passage of fluid, the diameter of which is much smaller than the diameter of the focusing ring. The throttling means is inserted into the descending longitudinal through section of the channel before the upper and lower parts are connected to each other.

The air gap is a through hole located in the downward longitudinal through section of the channel.

The disadvantage of this invention, described in the closest analogue, is that when assembling the device, the formed single channel for the passage of liquid drastically changes the diameter of the cross section along its length, which leads to a change in the flow rate. On the formed section of the single channel of the upper part, the section has a rectangular profile. The fluid entering the adapter hits the top wall of the rectangular portion, and the direction of flow changes dramatically. A change in the fluid flow rate with a sharp change in the direction of fluid flow leads to noise and vibration, and also increases the possibility of a turbulent mode.

The objective of the invention and the technical result achieved by using the invention is the development of an adapter for means of supplying a fluid that simultaneously reduces noise and vibration that occurs when the fluid flows through the adapter.

The task and the required technical result when using the adapter for the fluid supply means are achieved in that the adapter for the fluid supply means with a single fluid passage, consisting of an upper part provided with a connecting element, with a portion of a single channel located therein, and a lower part, made with ascending and descending through longitudinal sections of a single channel, throttling means and an air gap, a section of a single channel located in the upper part is formed when connecting the connecting element of the upper part to the lower part, it is made so that the part of the single channel, consisting of an ascending longitudinal section of the channel and the section of the single channel of the upper part, is configured to allow fluid to flow to the throttling means at a uniform speed, while the ascending longitudinal section the channel and the portion of the channel located in the upper part in liquid communication with it preferably have the same cross section, the connecting element is vertical The part’s henna is made in the form of an arc-shaped recess located inside the upper part, the outer upper surface of the lower part has a protrusion, repeating the shape of the recess, with a groove made along the entire length of the protrusion, repeating the shape of the protrusion and bounded by two side walls, and a single channel section located in the upper part, formed by connecting the upper and lower parts due to the internal free space of the recess of the upper part and the groove of the protrusion of the lower part and has a mostly arched shape, and o when connecting the upper and lower parts, the interconnected recess and the protrusion simultaneously serve as a means of fixing the upper and lower parts to each other, and by the fact that the recess of the upper part, the protrusion with a groove made along the entire length of the protrusion bounded by the side walls, means of throttling and the horizontal air gap of the lower part that communicates with it is formed during the casting of the upper and lower parts, and that the throttling means is made in the form of a through hole, communicating through air gap with a downward section of a single channel for the passage of fluid.

Disclosure of the invention is illustrated by figures 1, 2, 3 and 4.

In FIG. 1 shows an example of an adapter for a fluid supply device made in the form of a tap of a clean fluid.

In FIG. 2 shows an example embodiment of an adapter for a liquid supply means made in the form of a mixer with a supply line of pure liquid.

In FIG. 3 is a cross-sectional view of a portion of a single channel located in the upper part of FIG. 1.

In FIG. 4 shows a three-dimensional image of the upper surface of the lower part with a protrusion.

The adapter (1) for the fluid supply means consists of an upper part (2) and a lower part (3) (Fig. 1, 2).

In the upper part (2) there is a recess (4) of an arcuate shape, which is formed during casting of the upper part (2) (Fig. 1, 2).

In the lower part (3), ascending (7) and descending (8) through longitudinal sections of a single channel for the passage of fluid are made. The outer upper surface of the lower part (3) has a protrusion (5), repeating the shape of the recess (4) (Fig. 1, 2), with a groove (6) (Fig. 3, 4) made along the entire length of the protrusion (5), repeating the shape of the protrusion (5), (Fig. 4), and bounded by two side walls (13) (Fig. 3, 4).

When connecting the upper part (2) and the lower part (3), a section (9) of the single channel of the upper part (2) is formed (figures 1, 2, 3). When connecting the two parts, the side walls (13) of the protrusion (5) (Fig. 4) enter the recess (4) of the upper part (2) (Fig. 1, 2). Since the side walls (13) of the protrusion (5) (Fig. 3, 4) are made smaller than the height of the recess (4), the section (9) of a single channel located in the upper part (2) (Fig. 1, 2, 3 ), is formed due to the internal free space of the recess (4) and the groove (6), and the cross section of the section (9) of the single channel is, for example, an oval (Fig. 3). Since the recess (4) of the upper part (2) is made in an arcuate shape (Fig. 2), and the protrusion (5) with a groove (6) (Fig. 4) repeat the shape of the recess (4), the formed section of a single channel of the upper part ( 2) also acquires an arched shape (Fig. 1, 2). The formed section (9) of the single channel located in the upper part (2) is in fluid communication with the ascending longitudinal section (7) of the single channel of the lower part (3), and the diameter of the cross section of the section (9) of the single channel located in the upper part (2), by several millimeters it can exceed or be less than the diameter of the cross section of the ascending longitudinal section (7) of the single channel of the lower part (2) (Figs. 1 and 2).

Thus, in the adapter, the formed single channel for the passage of fluid has a part consisting of an ascending longitudinal section (7) and a section (9) of the single channel located in the upper part (2), in which the cross section of the single channel practically does not change along the entire length the specified part, and besides this, the formed section (9) of the single channel located in the upper part (2) has an arched shape, and, unlike the closest analogue, the transition from one section of the channel to another occurs smoothly without a sharp change section of the channel, thereby avoiding abrupt fluid hitting the single channel wall fluid passage provides a uniform rate of said portion of a single channel. The design of the adapter described above with a single channel for the passage of fluid formed in it leads to a simultaneous decrease in noise and vibration during the passage of fluid through a single channel, as well as to reduce the possibility of turbulent conditions.

In the lower part (2) there is a throttling device (10), made in the form of a through passage, which communicates with the descending longitudinal section (8) of a single channel for the passage of fluid through the air gap (11) (Figs. 1 and 2).

The air gap (11) is made in the form of a horizontal recess in the downward longitudinal section (8) of the single channel for the passage of liquid (Fig. 1 and 2) and communicates on the one hand with the throttling means (10) and with the descending longitudinal section (8) of the single channel for the passage of fluid on the other hand (Fig. 1 and 2).

In contrast to the closest analogue, where the throttling means is a separate part, the throttling means (10) in the claimed invention is part of the lower part (3).

It should be noted that the recess (4) of the upper part (2), the protrusion (5) with a groove (6) (Fig. 3, 4), made along the entire length of the protrusion (5) and limited by the side walls (13), means of throttling ( 10) and the associated air gap (11) of the lower part (3) are formed during casting of the upper (2) and lower parts (3). Due to this, there is an additional reduction in noise and vibration during the passage of fluid through a single channel, as well as the assembly of the adapter is faster and more convenient.

By connecting the recess (4) of the upper part (2) and the protrusion (5) of the lower part (3), two parts are additionally fixed before soldering or gluing. After joining the upper (2) and lower (3) parts, they are welded or glued together using, for example, cyanoacrylate glue.

Glued parts can be placed in the housing (12) (Fig. 1).

The figure 1 shows the design of the adapter (1) for a fluid supply device made in the form of a tap of a clean liquid (not shown in the figures), where the ascending (7) and descending (8) through longitudinal sections protrude from the lower outer surface of the lower part (3) for the convenience of fixing the fluid tubes, and the upper (2) and lower (3) adapter parts can be made, for the most part, of a cylindrical shape.

The figure 2 shows the design of the adapter (1) for the liquid supply means, made in the form of a mixer with a clean liquid supply line (not shown in the figure), where the adapter is made with a length much greater than the width. In contrast to the adapter shown in FIG. 1, the upper (2) and lower (3) adapter parts are made, for example, in an arcuate or S-shape in cross section.

As part of the distinguishing features, the adapter described above works as follows.

The fluid enters the ascending longitudinal through section (7) of the single channel, passes the section (9) of the single channel located in the upper part (2), the cross section of which preferably coincides with the section of the ascending longitudinal through section and with increased speed through the throttling means (10), made, for example, in the form of a through hole, passes through the air gap (11) into a downward longitudinal through channel (8) and is discharged from the adapter (1).

In the present description of the invention presents a preferred embodiment of the invention. Changes can be made in it, within the scope of the claimed formula, which makes it possible to widely use it.
