[0002] The pressure-stabilizing and reducing valve (also known as the pressure reducing valve) controls the opening of the opening and closing parts in the valve body to adjust the flow of the medium, reduce the pressure of the medium, and at the same time adjust the opening of the opening and closing parts with the help of the pressure behind the valve to keep the pressure behind the valve within a certain range. When the inlet pressure keeps changing, the outlet pressure is kept within the set range to protect the subsequent life and production equipment.

[0003] During the use of the pressure-stabilizing and reducing valve, after the user adjusts the docking pressure of the valve, it is often difficult to keep it stable under the corresponding pressure, resulting in unstable flow of the fluid medium through the valve body per unit time, thus affecting the normal use of the pressure reducing valve.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0022] Reference Figure 1 and Figure 5In the embodiment of the present invention, the adjustable high-sensitivity pressure-stabilizing pressure reducing valve comprises a pressure reducing valve body 1, an inlet pipe 3 is fixedly installed at one end of the pressure reducing valve body 1, and a discharge pipe 4 is fixedly installed at the other end of the pressure reducing valve body 1 opposite to the inlet pipe 3, and a flow control component 5 is arranged inside the discharge pipe 4 and the inlet pipe 3, and the flow control component 5 comprises an inflatable rubber ring 51 arranged inside the inlet pipe 3, a fixed outer plate 52 fixedly installed on the outer periphery of the inflatable rubber ring 51, and a fixed outer plate 52 is provided on the outer periphery of the fixed outer plate 52 for the inflatable rubber ring 51 to be filled with air. An inflatable port 53 for inflating the ring 51, a through hole 54 adapted to the inflatable port 53 is opened on the periphery of the inlet tube 3, a micro air pump 58 for inflating the inflatable rubber ring 51 is fixedly installed on the periphery of the inlet tube 3, an air supply pipe 510 is fixedly installed on the top of the micro air pump 58, an air inlet pipe 59 is fixedly installed on one end of the air supply pipe 510, an air delivery pipe 57 is fixedly installed on one end of the air supply pipe 510, and a connecting air pipe 56 is fixedly installed on one end of the air delivery pipe 57, and the connecting air pipe 56 passes through the through hole 54 and is connected to the inflatable port 53;

[0023] Through the implementation of this method: the micro air pump 58 is a micro piston pump, which is equipped with a portable power supply inside. It has a relatively compact structure and can provide a higher pressure and a relatively large flow rate. The gas is sucked in and discharged by the reciprocating motion of the piston in the cylinder. The inflatable rubber ring 51 is inflated by the micro air pump 58 to increase the volume of the inflatable rubber ring 51 inside the inlet pipe 3 and reduce the flow rate of the medium. The inflatable rubber ring 51 is deflated by the micro air pump 58 to increase the flow rate of the medium flowing into the inlet pipe 3. The flow control component 5 can be used to change the flow rate inside the inlet pipe 3 and the outlet pipe 4 in a portable manner, thereby increasing the stability of the use of the pressure reducing valve body 1.

[0024] Reference Figure 1 and Figure 5 A clamping groove 511 is provided inside the entry tube 3 and is slidably engaged with the fixed outer plate 52. The clamping groove 511 is evenly arranged around the entry tube 3. A first clamping slide bar 55 is fixedly installed on the outer periphery of the fixed outer plate 52 and is slidably engaged with the clamping groove 511.

[0025] Through the implementation of this method: through the snap-fitting slide groove 511 and the first snap-fitting slide rod 55, when the inflatable rubber ring 51 is aged and damaged in the later stage, it is convenient for the staff to carry out portable replacement and installation.

[0026] Reference Figure 1 and Figure 5 A protective mesh plate 512 is provided near the inlet of the pipe 3 to reduce the wear of the inflatable rubber ring 51 by solid particles in the medium;

[0027] Through the implementation of this method, the solid particles in the circulating medium can be blocked by the protective mesh plate 512, thereby reducing the damage caused by friction between the solid particles and the inflatable rubber ring 51.

[0028] Reference Figure 1 and Figure 5 A second clamping slide bar 513 adapted to the clamping slide groove 511 is fixedly installed on the outer periphery of the protective mesh plate 512, and the second clamping slide bar 513 is evenly fixedly installed around the outer periphery of the protective mesh plate 512, and the cross-sections of the clamping slide groove 511, the first clamping slide bar 55 and the second clamping slide bar 513 are all T-shaped;

[0029] Through the implementation of this method: the T-shaped structure enables the slider to better resist lateral force in the slide groove. Compared with other shapes, the vertical part of the T-shaped slider can be embedded in the corresponding part of the slide groove, effectively preventing the slider from deflecting or falling out when subjected to lateral force.

[0030] Reference Figure 1 and Figure 5 A valve seat 2 is fixedly installed on the top of the pressure reducing valve body 1 to facilitate the user to adjust the pressure.

[0031] The working principle of the present invention is: when the pressure reducing valve body 1 is used, if it is necessary to change the flow diameter inside the inlet pipe 3 or the outlet pipe 4, the staff only needs to start the micro air pump 58. The start of the micro air pump 58 will intake air from the air inlet pipe 59, exhaust air from the air supply pipe 510, and inflate the inflatable rubber ring 51 inside the inlet pipe 3 or the outlet pipe 4 through the air delivery pipe 57 and the connecting air pipe 56. Through inflation, the volume of the inflatable rubber ring 51 expands inside the inlet pipe 3 or the outlet pipe 4, reducing the flow diameter inside the inlet pipe 3 or the outlet pipe 4, reducing the unstable flow of the pressure reducing valve body 1 during use, and increasing the stability of use. At the same time, the protective mesh plate 512 set at the entrance of the inlet pipe 3 can block the solid particles in the circulating medium, reduce the damage caused by friction between the solid particles and the inflatable rubber ring 51, and increase the service life of the inflatable rubber ring 51.

[0032] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
