Description

Current stabilizer

Technical Field

The present invention relates to devices for stabilizing the flow of liquids at different pressures.

Background

In a specific water supply system, the water flow is in direct proportion to the square root of the water pressure, the water pressure is high, and the water flow is high, otherwise, the water flow is low. Different areas, different residence levels and different periods have different tap water supply pressures. In many applications, it is desirable to achieve a stable water flow at different water pressures, such as in a toilet bowl, where flushing is not possible if the water flow is insufficient and water is wasted if the water flow is excessive. In order to obtain stable water flow, the diaphragm type current stabilizer in the prior art is shown in fig. 1, and is provided with a film seat a, a rubber sheet b is arranged on the water inlet direction of the film seat a, a boss a2 is arranged on one surface of the film seat a opposite to the rubber sheet b in the center direction, a bulge a1 circumferentially spaced is arranged on the periphery direction, the bulge a2 is blocked by the boss a1, a flow channel c is formed between the rubber sheet b and the film seat a, the flow channel c is communicated with a water outlet channel a3 of the film seat, and water flows out through the flow channel c and the water outlet channel a 3. The water inlet pressure makes the rubber sheet b deform, the water pressure is high, the deformation of the rubber sheet b makes the flow channel c narrow, the water flow is small, and the water flow is kept stable by counteracting the water flow increasing part due to the increase of the water pressure. However, such prior art flow stabilizers, as shown in Table 1 and FIG. 9, showed that the water flow rate remained substantially stable in the relatively medium-high pressure region of the water supply static pressure of 0.24-0.55 MPa, and the water flow rate was not stable in the relatively low pressure region of the static pressure of 0.08-0.24 MPa, and the water flow rate in this region was relatively small, as demonstrated in the water inlet test of the toilet bowl rim. The current water valve generally uses water pressure of 0.03-0.8 Mpa, so the current stabilizer in the prior art has no current stabilizing function in a relatively low water pressure area and has small water flow.

In order to solve the problems, the invention adopts the technical scheme that a retainer ring seat and a plastic retainer ring are arranged, one surface of the retainer ring seat is provided with a convex ring and a convex top with circumferential intervals, the circumferential radius of the convex ring is smaller than the circumferential radius of the convex top, the plastic retainer ring is close to the convex ring and the convex top, so that a water inlet channel B' is formed between the plastic retainer ring and the retainer ring seat and is communicated with a water outlet channel B (1-3) arranged near the periphery of the retainer ring seat; the device is characterized in that a radial outward-expansion water outlet channel A' is arranged at the center of the retainer ring seat; the retainer ring seat is connected with a core sleeve, the core sleeve is provided with a water outlet channel A, the water outlet channel A is communicated with the water outlet channel A', the other end direction of the core sleeve, which is opposite to the one end direction of the water outlet channel A, is provided with a ring table A and a ring table B which are radially outwards expanded, a rubber ring is arranged on the ring table A, an overcurrent core body is sleeved in the corresponding position of the ring table B, the overcurrent core body is provided with a water inlet channel A, the water inlet channel A is communicated with the water outlet channel A of the sleeve core, and the water inlet channel A is communicated with a ring cavity where the rubber ring is positioned; the periphery of the core sleeve is provided with a radial contraction part, the periphery of the radial contraction part is formed into a water inlet channel B, and the water inlet channel B is communicated with the water inlet channel B'.

Suitably, the radial contraction parts of the core sleeve are circumferentially and uniformly distributed, and radial extension convex edges are arranged between the radial contraction parts.

Preferably, the overcurrent core is provided with an inner core with a cross section in a shape of a Chinese character 'mi', so that the inner core is provided with eight radial extension side wings, wherein four radial symmetry side wings are connected with the inner wall of the overcurrent core, and the water inlet channel A is formed among the four side wings connected with the inner wall of the overcurrent core.

Detailed Description

A current stabilizer is provided with a retainer seat 1 and a plastic retainer 2, wherein one surface of the retainer seat 1 is provided with a convex ring 1-2 and four convex tops 1-, which are circumferentially spaced and uniformly distributed, the circumferential radius of the convex ring 1-2 is smaller than the circumferential radius of the convex top 1-1, the plastic retainer 2 is abutted against the convex ring 1-2 and the convex top 1-1, a water inlet channel B '6-1 is formed between the plastic retainer 2 and the retainer seat 1, and the water inlet channel B' is communicated with a water outlet channel B1-3 arranged near the periphery of the retainer seat; the center of the retainer ring seat 1 is provided with a radial outward-expansion water outlet channel A'1-4; the annular inner wall 1-5 corresponding to the convex ring 1-2 of the retainer seat 1 is sleeved with a core sleeve 3, the core sleeve 3 is provided with a water outlet channel A3-1, the water outlet channel A3-1 is communicated with the water outlet channel A'1-4, the plastic retainer 2 is sleeved on the outer wall of the water outlet channel A3-1 of the core sleeve 3, the other end direction of the core sleeve 3, opposite to the direction of one end of the water outlet channel A3-1, is provided with a ring platform A and a ring platform B which are radially outwards expanded, the ring platform A is provided with a rubber ring 4, an overcurrent core body 5 is sleeved in the position corresponding to the ring platform B, the overcurrent core body 5 is provided with a water inlet channel A5-1, the water inlet channel A5-1 is communicated with the water outlet channel A3-1 of the core sleeve, and the water inlet channel A5-1 is communicated with a ring cavity where the rubber ring 2 is positioned; the periphery of the core sleeve 3 is provided with a radial contraction part 3-2, the periphery of the radial contraction part is formed into a water inlet channel B6, namely, the current stabilizer is arranged on a pipeline, a water inlet channel B6 is formed between the radial contraction part 3-2 and the inner wall of the pipeline, as shown in fig. 8, and the water inlet channel B6 is communicated with the water inlet channel B' 6-1. The radial contraction part 3-2 of the core sleeve 3 is provided with four circumferentially uniformly distributed ribs 3-3 which extend radially between the radial contraction parts 3-2. The overcurrent core body 5 is provided with an inner core 5-2 with a cross section in a shape of a Chinese character 'mi', so that the inner core is provided with eight radial extension side wings, wherein four radial symmetry side wings are connected with the inner wall of the overcurrent core body 5, and a water inlet channel A5-1 is formed among the four side wings connected with the inner wall of the overcurrent core body 5.

The current stabilizer can be divided into two parts according to a flow channel, wherein the first part consists of a retainer ring seat 1 and a plastic retainer ring 2, and the second part consists of a core sleeve 3, a rubber ring 4 and an overcurrent core body 5. In use, the first part of the through flow is throttled into a first water flow, the second part of the through flow is throttled into a second water flow, and the two water flows are collected and output in the mounting pipe. The first water flow is input from a water inlet channel B6 and a water inlet channel B'6-1, and is output from a water outlet channel B1-3; the second water flow is input from the water inlet channel A5-1, and the water outlet channel A3-1 and the water outlet channel A'1-4 are output.

The plastic retainer ring 2 is deformed by the water pressure during the first water flow input, and the large deformation of the water pressure is realized. The plastic retainer ring 2 deforms to narrow the water inlet channel B', so that throttling is generated, and the water pressure is large and the narrowing degree is large. The deformation throttling of the plastic retainer ring 2 and the increase of the water pressure increase flow have a mutual offset relation, and the specific offset situation is related to the throttling sensitivity of the plastic retainer ring 2. The plastic retainer ring 2 can be made of rubber, latex and other materials, and the plastic retainer ring is thinner, softer and more sensitive.

The first portion, the first water flow, is similar to the prior art diaphragm type flow stabilizer and the difference in the two throttling characteristics is described below.

The water pressure and flow test data for prior art current stabilizers in a water stream are shown in table 1.

TABLE 1 current stabilizer water pressure and flow

Static pressure Mpa	Flow rate L/min
		0.08	10.36
0.1	12.1
		0.15	13.48
0.24	15.68
		0.35	15.48
0.55	15.72

The water pressure-flow curve of the prior art flow stabilizer is shown in fig. 9.

The limitation or defect of the current stabilizer in the prior art is that the flow rate of the relatively middle water pressure area and the high water pressure area can be stabilized in a required range, and the flow rate of the relatively low water pressure area is unstable and is small.

The water pressure and flow data of the first portion, the first water stream, of the present invention under test conditions similar to prior art current stabilizers are shown in table 2.

TABLE 2 first water pressure and flow of the invention

Static pressure Mpa	Flow rate L/min
		0.083	3.76
0.1	3.12
		0.15	2.36
0.2	2.0
		0.3	1.64
0.4	0.8
		0.5	0.6
0.6	0.36
		0.7	0.2
0.8	0.12

The first water pressure-flow curve of the present invention is shown by curve 1-in fig. 10.

The throttle sensitivity of the plastic collar 2 was described above. The rubber sheet b of the prior art stabilizer shown in fig. 1 corresponds to the plastic retainer ring 2 of the present invention, and it is apparent that the plastic retainer ring 2 of the present invention is much higher in throttle sensitivity than the rubber sheet b of the prior art, but this is not a matter of quality, but both are due to compliance with functional requirements.

When the second water flow is input, the water flow of the water inlet channel A5-1 impacts the rubber ring 4, the rubber ring 4 deforms to extend towards the circle center, the flow passage is narrowed, throttling is generated, and the water pressure and flow data are shown in the table 3.

TABLE 3 Water pressure and flow of the second Water flow of the invention

The second water pressure-flow curve of the present invention is represented by curve 2-of fig. 10.

The first and second portions of the present invention are combined, the first and second water flow rates are summed, and the overall test, the water pressure-flow curve, is represented by curve 3-of fig. 10.

The invention can stabilize the water flow in 12.372-15.6L/min in the range of relatively low, medium and high water pressures of 0.083-0.8 Mpa, and meets the required requirements. The invention has simple structure, easy manufacture and assembly, lower cost and long service life.
