Description

TECHNICAL FIELD

[0001] The utility model belongs to water supply equipment technical field, concretely relates to a water delivery silencer and water supply equipment. BACKGROUND

[0002] Secondary water supply refers to the form that units or individuals store, pressurize city public water supply or self-built water supply facilities, and supply users or self-use through pipelines. Secondary water supply is mainly established to compensate for the lack of municipal water supply pipeline pressure and guarantee water use of high-rise population. The secondary water supply equipment is usually arranged on the ground or in the basement. The equipment is used for scheduling peak water consumption and increasing water pressure, so that it can meet large-area water consumption and high-floor water consumption during peak water consumption. The secondary water supply equipment usually uses a water tank to store water, and a water pump is used to extract water for user use.

[0003] When the water tank is at a low liquid level, the water tank needs to be replenished. During the water tank water inlet process, since tap water has a certain pressure and pressure fluctuation occurs, and there is a certain height difference between the water inlet pipe orifice and the water tank liquid level, the water flow is suddenly released at the water tank water outlet, which will impact the water tank bottom and side wall. Long-term impact will reduce the service life of the water tank, and also generate vibration and noise, affecting the normal life of nearby residents.

[0004] Therefore, it is urgent to provide a water delivery silencer and water supply equipment to solve the above problems. UTILITY MODEL CONTENTS

[0005] The utility model aims at least to solve the problem of how to reduce the noise and vibration when the water tank is filled with water. The purpose is achieved by the following technical solutions:

[0006] The utility model discloses a kind of water delivery silencers for the water tank water inlet, and the water delivery silencer includes:

[0007] Water delivery pipe;

[0008] Silencing cylinder, the silencing cylinder includes cylinder main body and cylinder bottom plate, the cylinder main body is connected to the water outlet end of the water delivery pipe, the cylinder bottom plate is connected to the end of the cylinder main body away from the water delivery pipe, a plurality of first silencing water outlet holes are arranged on the cylinder main body, and the first silencing water outlet hole is used for water outlet.

[0009] The water delivery silencer provided by the technical scheme utilizes the principle of orifice plate pressure reduction in fluid mechanics. According to Bernoulli's principle, under ideal conditions, the sum of kinetic energy, potential energy and pressure potential energy of unit volume fluid at any cross section of the same flow pipe is a constant. The most famous inference is that when the flow is at the same height, the greater the flow rate, the smaller the pressure (the pressure in fluid mechanics actually refers to the pressure per unit area, that is, the pressure in ordinary physics). Therefore, a plurality of first sound-absorbing water outlets are arranged on the cylinder body, when water flows into the sound-absorbing cylinder through the water delivery pipe, the first sound-absorbing water outlets accelerate the flow rate of the water flow and reduce the pressure, which can effectively reduce the impact of the water flow on the bottom and the surrounding sidewall of the water tank. At the same time, due to the arrangement of the cylinder bottom plate and the first sound-absorbing water outlets, the direction of the water flow is changed from the original unified downward to the surrounding dispersion, thereby reducing the noise and vibration caused by the water flow impacting the water tank. In addition, due to the light weight of air, the air mixed in the water flow can be discharged through the first sound-absorbing water outlets above, thereby helping to eliminate the humming or whistling inside the water delivery silencer.

[0033] Figure 1 Fig. 1 schematically shows a structure schematic view of a water delivery silencer according to an embodiment of the present application in a certain perspective. Figure 2 Fig. 2 schematically shows a structure schematic view of a silencer cylinder 200 according to an embodiment of the present application. As shown in Fig. 2, Figure 1 and Figure 2 The present application provides a water delivery silencer, which comprises a water delivery pipe 100 and a silencer cylinder 200. The water delivery pipe 100 is used for water inlet. The silencer cylinder 200 comprises a cylinder main body 210 and a cylinder bottom plate 220. The cylinder main body 210 is connected to a water outlet end of the water delivery pipe 100. The cylinder bottom plate 220 is connected to an end of the cylinder main body 210 which is away from the water delivery pipe 100. A plurality of first silencing water outlet holes 211 are arranged on the cylinder main body 210, and the first silencing water outlet holes 211 are used for water outlet.

[0034] The water delivery silencer provided by the present application utilizes the principle of orifice plate pressure reduction in fluid mechanics. According to Bernoulli's principle, under ideal conditions, the sum of kinetic energy, potential energy and pressure potential energy of unit volume of fluid at any cross section of the same flow pipe is a constant. The most famous inference is that when the flow is at the same height, the greater the flow rate, the smaller the pressure (the pressure in fluid mechanics actually refers to the pressure per unit area, that is, the pressure in ordinary physics). Therefore, a plurality of first silencing water outlet holes 211 are arranged on the cylinder main body 210. When the water flow flows into the silencer cylinder 200 through the water delivery pipe 100, the first silencing water outlet holes 211 accelerate the water flow and reduce the pressure, which can effectively reduce the impact of the water flow on the bottom and the peripheral sidewall of the water tank 500. At the same time, due to the arrangement of the cylinder bottom plate 220 and the first silencing water outlet holes 211, the water flow direction changes from the original unified downward to the peripheral dispersion, thereby reducing the noise and vibration caused by the water flow impact on the water tank 500. In addition, since the air is lighter in weight, the air mixed in the water flow can be discharged through the first silencing water outlet holes 211 above, thereby helping to eliminate the humming or whistling inside the water delivery silencer.

[0035] Further, with reference to the drawings Figure 1 and Figure 2 The water delivery silencer further comprises a clamp 400, and the barrel body 210 and the water delivery pipe 100 are connected through the clamp 400. Optionally, the end, where the water delivery pipe 100 and the barrel body 210 are connected, is provided with a first clamping groove 212, and the end, where the barrel body 210 and the water delivery pipe 100 are connected, is provided with a second clamping groove, the clamp 400 comprises two half-ring bodies, each half-ring body is provided with a connecting part at two ends, and the inner wall of each half-ring body is provided with a first clamping protrusion and a second clamping protrusion. During assembly, the first clamping protrusion and the second clamping protrusion are clamped into the first clamping groove 212 and the second clamping groove respectively, and then the adjacent connecting parts are locked by bolts. Optionally, in other embodiments, the water delivery pipe 100 and the barrel body 210 can also be connected through threads or through flanges. Optionally, the water inlet end of the water delivery pipe 100 is provided with a connecting flange 110, which is used for connecting with a water flow delivery pipeline.

[0036] Further, a plurality of rows of first silencing water outlet holes 211 are arranged along the axial direction of the barrel body 210, and each row comprises a plurality of first silencing water outlet holes 211 arranged along the circumferential direction of the barrel body 210. The flow areas of the plurality of first silencing water outlet holes 211 on the barrel body 210 are the same in size. Exemplarily, the number of rows of the first silencing water outlet holes 211 can be one row, two rows, three rows, five rows or seven rows, etc., and each row can comprise one or more silencing water outlet holes. Optionally, the first silencing water outlet hole 211 can be a circular hole, the diameter of which is less than 1 mm, and the spacing between adjacent second silencing water outlet holes 221 is less than 0.5 mm.

[0037] Figure 3 The structure schematic diagram of the silencing barrel 200 according to another embodiment of the present application is schematically shown. With reference to Figure 3 In the present embodiment, the flow area of the first silencing water outlet hole 211 gradually decreases in the direction from the water inlet end of the barrel body 210 to the barrel bottom plate 220. Specifically, a plurality of rows of first silencing water outlet holes 211 are arranged along the axial direction of the barrel body 210, each row comprises a plurality of first silencing water outlet holes 211 arranged along the circumferential direction of the barrel body 210, the diameters of the first silencing water outlet holes 211 in each row are the same, and the flow areas of the first silencing water outlet holes 211 gradually decrease in the direction from the water inlet end of the barrel body 210 to the barrel bottom plate 220. The reason for adopting this arrangement is that the pressure in the upper part of the cavity is large, and the first silencing water outlet hole 211 with a larger diameter is more conducive to pressure reduction, while the pressure in the lower part of the cavity is small, and reducing the diameter of the first silencing water outlet hole 211 can improve the flow rate, so that the pressure reduction effect is better.

[0038] Further, the cylinder body 210 comprises a first section 210a and a second section 210b connected with each other, the inner diameter of the first section 210a is smaller than that of the second section 210b, the first section 210a is connected with the water delivery pipe 100, the cylinder bottom plate 220 is connected to an end of the second section 210b away from the first section 210a, and the first sound-attenuating water outlet hole 211 is arranged on the second section 210b. It can be understood that, in the flow direction of the water flow, the increase of the inner diameter of the cylinder body 210 can reduce the flow rate of the water flow, and the slow-down of the water flow can effectively reduce the flow resistance and pressure loss, thereby reducing the noise and vibration inside the cavity.

[0039] Optionally, the cylinder body 210 further comprises a transition section 210c, a first end of the transition section 210c is connected to the first section 210a, and a second end of the transition section 210c is connected to the second section 210b, and the inner diameter of the transition section 210c gradually increases in the direction from the first end to the second end. Of course, in another embodiment, the first section 210a and the second section 210b can also be connected through an annular connecting plate. In other embodiments, the entire cylinder body 210 can also be arranged in a structure with the inner diameter gradually decreasing from the water inlet direction to the water outlet direction. Optionally, the cylinder body 210 is in an integral forming structure, and the material thereof can be stainless steel.

Referring to FIG. 4, the cylinder body 210 is arranged in the water tank 500, and the water inlet hole 201 is arranged on the water tank 500. The water inlet hole 201 is connected with the water inlet pipe 200, and the water outlet pipe 100 is connected with the water outlet hole 202.

The water inlet pipe 200 is connected with the water inlet hole 201, and the water outlet pipe 100 is connected with the water outlet hole 202. Figure 4 Further, a plurality of second sound-attenuating water outlet holes 221 are arranged on the cylinder bottom plate 220, and the second sound-attenuating water outlet holes 221 are used for water outlet. It can be understood that the water flow inside the sound-attenuating cylinder 200 can be discharged into the water tank 500 through the second sound-attenuating water outlet holes 221, and the arrangement of the second sound-attenuating water outlet holes 221 increases the water outlet amount of the water flow, thereby increasing the water inlet efficiency. Similarly, the second sound-attenuating water outlet holes 221 also have the effects of increasing the flow rate of the water flow and reducing the pressure, thereby reducing the impact of the water flow on the bottom of the water tank 500, and thereby reducing the vibration and noise of the water tank 500. Optionally, the flow areas of the plurality of second sound-attenuating water outlet holes 221 are the same, and the second sound-attenuating water outlet holes 221 are arranged on the cylinder bottom plate 220 according to the shape of the cylinder bottom plate 220. Exemplarily, the second sound-attenuating water outlet holes 221 can be circular holes, the diameter of each of the second sound-attenuating water outlet holes 221 is less than 1 mm, and the spacing between adjacent second sound-attenuating water outlet holes 221 is less than 0.5 mm.

Optionally, the cleaning brush 310 comprises a connecting rod and bristles, the connecting rod is arranged along the radial direction of the cylinder bottom plate 220, and the bristles are connected to the connecting rod. Optionally, the connecting rod can be in the shape of a Chinese character or a cross, so as to avoid the bristles from blocking the second muffling water outlet hole 221.

[0043] Further, one end of the rotating shaft 320 penetrates out of the cylinder bottom plate 220, and a snap ring 330 is sleeved on the end of the rotating shaft 320 penetrating out of the cylinder bottom plate 220.
