Description

Technical Field

[0001] The invention relates to the field of water flow regulating and pressure regulating devices, and in particular to an automatic control flow regulating and pressure stabilizing device. Background Art

[0002] With the development of water conservancy and electric power industries, the normal operation of various pipeline systems needs to be guaranteed, and the demand for water flow regulating and pressure regulating devices is also increasing. In different situations, the flow and pressure of water flow need to be adjusted according to different needs, and the water flow will increase or decrease with the changes in the surrounding environment, and the pressure in the pipeline will also increase or decrease accordingly, which brings inconvenience to people. Some of the flow regulating and pressure regulating devices currently used have complex structures, require manual adjustment, and are expensive and not suitable for large-scale applications. Therefore, we need an automatic control flow regulating and pressure stabilizing device with simple structure, cost saving, and the ability to achieve automatic flow regulating and pressure stabilization. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic control flow regulating and pressure stabilizing device which can regulate water flow according to water pressure changes.

[0004] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0005] The present invention proposes an automatic control flow regulating, pressure regulating and stabilizing device, comprising a guide tube, a piston assembly and an outer sleeve, wherein a plurality of water outlet waist holes are opened on the lower end side wall of the guide tube, the piston assembly comprises a piston sleeve, the piston sleeve is sleeved on the guide tube, the outer sleeve is sleeved on the guide tube, the inner side of the outer sleeve is provided with a groove, which forms a guide cavity with the guide tube and the side walls of the piston assembly, and the water outlet waist hole of the guide tube is connected with the guide cavity.

[0006] Furthermore, a return spring is arranged in the piston sleeve, one end of the return spring is fixedly connected to the end of the guide tube, and the other end of the return spring is arranged with a valve cover.

[0007] Furthermore, the water outlet waist hole is strip-shaped and elliptical.

[0008] Furthermore, the front and rear ends of the outer sleeve both have convex extensions.

[0009] Furthermore, the air outlet of the piston assembly is connected to the outside of the outer sleeve.

[0010] Furthermore, a first sealing ring is provided at the connection between the valve cover and the piston sleeve, and a second sealing ring is provided at the connection between the piston sleeve and the flow guide pipe.

[0011] The present invention also relates to an automatic control current regulation, voltage regulation and voltage stabilization method, using the automatic control current regulation, voltage regulation and voltage stabilization device as described above, and the specific steps are as follows:

[0012] The water inlet and the water outlet of the flow guide pipe of the pressure stabilizing device are both connected to the pipeline;

[0013] After the water flows into the guide pipe, it flows from the inner cavity of the guide pipe through the water outlet waist hole into the guide cavity and then flows to the water outlet. As the water flow pressure increases, the inner cavity of the guide pipe and the inner cavity area of ​​the piston assembly are both in a water pressure state. The piston assembly moves to the right under the water flow pressure, and the outer wall of the piston assembly approaches the water outlet, making the water outlet area smaller. When the water flow pressure is less than a certain range, the water flow pressure is too small to offset the spring force and friction force, so the piston assembly moves to the left, increasing the area of ​​the water outlet, and the water will flow directly out of the water outlet waist hole, flow through the guide cavity to the water outlet, thereby regulating the flow and pressure of the water.

[0014] The beneficial effects of the present invention are as follows: when the water pressure is greater than a certain range, as the pressure increases, the air in the cavity is discharged from the exhaust hole, and the piston moves to the right to reduce the area of ​​the water outlet. When the water pressure is less than a certain range, the spring force and friction of the device cannot be offset, the cavity inhales air from the air inlet, and the piston moves to the left to increase the area of ​​the water outlet. At the same time, the corresponding parameters can be designed according to the relationship between the size of the spring force, the water pressure, and the size of the water outlet, so that after the water inlet reaches a certain pressure, the water outlet pressure is stabilized within a certain range, and the effect of regulating flow, regulating pressure, and stabilizing pressure can be better achieved.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] See also Figures 1 to 4 , the present invention provides an embodiment:

[0022] See also Figure 1 and Figure 3 An automatic control flow regulating and voltage stabilizing device includes a guide tube 1, a piston assembly and an outer sleeve 2. A plurality of water outlet waist holes 6 are opened on the lower end side wall of the guide tube 1. The piston assembly includes a piston sleeve 3. The piston sleeve 3 is sleeved on the guide tube 1. The outer sleeve 2 is sleeved on the guide tube 1. The inner side of the outer sleeve 2 has a groove that forms a guide cavity 7 with the guide tube 1 and the side wall of the piston assembly. The water outlet waist hole 6 of the guide tube 1 is connected with the guide cavity 7.

[0023] See also Figure 1 and Figure 3 A return spring 4 is arranged in the piston sleeve 3, one end of the return spring 4 is fixedly connected to the end of the guide tube 1, and the other end of the return spring 4 is provided with a valve cover 5. The valve cover 5 is fixed to the piston sleeve 3 by bolts 11.

[0024] See also Figure 1 and Figure 3 , the water outlet waist hole 6 is a strip elliptical shape.

[0025] See also Figure 1 and Figure 3 The front and rear ends of the outer sleeve 2 both have convex extensions.

[0026] See also Figure 1 The air outlet 8 of the piston assembly is connected to the outside of the outer sleeve 2.

[0027] See also Figure 1 and Figure 2 A first sealing ring 10 is provided at the connection between the valve cover 5 and the piston sleeve 3, and a second sealing ring 12 is provided at the connection between the piston sleeve 3 and the flow guide tube 1. The sealing ring is used to achieve sealing, thereby cutting off the water flow and preventing water leakage.

[0028] Working principle: Area A is in a water pressure state, and area B is in an atmospheric pressure state. Water flows into the guide tube 1. When the water pressure reaches a certain value, as the pressure increases, the cavity 9 in area B discharges air from the air outlet 8 to ensure that area B is always in an atmospheric pressure state. The piston assembly moves to the right to reduce the area of ​​the water outlet. When the water pressure is less than a certain range, the water pressure is too small to offset the spring force and friction force. The cavity 9 in the piston assembly inhales air from the air outlet 8, and the piston assembly moves to the left to increase the area of ​​the water outlet. The water will flow directly out of the water outlet waist hole 6 and flow to the water outlet through the guide cavity 7, thereby regulating the water flow and stabilizing the pressure.
