Abstract
Description
Technical Field
[0001] This invention relates to the field of coating equipment and chemical conveying systems, and more specifically to a pressure stabilizing system. Background Technology
[0002] In existing technologies, hydraulic systems typically include pressure regulators to stabilize the fluid flow. These regulators are usually diaphragm-type structures, with the inner diaphragm fixed between two carbon steel halves of a diaphragm-type pressure tank via hot rolling. The hydraulic and pneumatic components are separated by the diaphragm, resulting in a 1:1 pressure transmission ratio; that is, when the hydraulic operating pressure is 30 MPa, the pneumatic pressure will also reach 30 MPa. However, in this type of regulator, because the diaphragm is in direct contact with the fluid, existing diaphragms are unsuitable for corrosive media. Using corrosion-resistant diaphragms might compromise the pressure transmission efficiency and increase operating costs.
[0003] Therefore, it is necessary to improve the pressure regulators in existing hydraulic systems so that they can meet the requirements of long service life, simple structure, and wide application while maintaining normal operating performance. Summary of the Invention
[0004] In view of this, the present invention provides a pressure stabilizing system that uses a pressure regulator installed in the system to stabilize the fluid medium in the fluid channel. The pressure regulator separates the pressure stabilizing chamber and the cylinder and connects them using a plunger assembly, which completely solves the problem of the diaphragm of the previous hydraulic pressure regulator being incompatible with corrosive media. At the same time, it has the characteristics of simple structure, wide application, convenient disassembly and assembly, and significant pressure stabilization.
[0005] The present invention provides a voltage stabilization system, including a fluid channel for fluid medium flow and a voltage regulator for stabilizing the pressure of the fluid medium. The voltage regulator is provided with an inlet for fluid medium to flow in and an outlet for fluid medium to flow out. The fluid medium in the fluid channel flows into the voltage regulator from the inlet and flows out from the outlet of the voltage regulator.
[0006] Furthermore, the pressure regulator includes a cylinder filled with a gas medium and a pressure regulating chamber for stabilizing the fluid medium. The fluid medium inlet and outlet of the pressure regulator are located on the pressure regulating chamber. The cylinder is provided with an air inlet for the gas medium to enter and an air outlet for the gas medium to exit. The pressure regulating chamber is located at the bottom of the cylinder. A plunger assembly is provided inside the cylinder, and the bottom of the plunger assembly extends into the pressure regulating chamber. The gas medium inside the cylinder acts on the plunger assembly and stabilizes the fluid medium in the pressure regulating chamber through the plunger assembly.
[0007] Furthermore, the plunger assembly includes a piston and a plunger rod. The piston is disposed in the cavity of the cylinder and divides the cavity into an upper cavity and a lower cavity. The gas medium in the cylinder fills the upper cavity, and the lower cavity is connected to the atmospheric pressure.
[0008] Furthermore, the plunger rod is disposed in the lower cavity of the cylinder and its upper end is fixedly connected to the piston. The lower end of the plunger rod extends into the pressure stabilizing cavity and acts on the fluid medium in the pressure stabilizing cavity.
[0009] Furthermore, the cylinder is equipped with a gas medium input valve connected to the air inlet and a gas medium output valve connected to the air outlet. The gas medium is input into the upper cavity of the cylinder through the gas medium input valve and output through the gas medium output valve.
[0010] Furthermore, it also includes a pressure regulating valve installed at the cylinder inlet, which is used to regulate the pressure of the gas medium in the upper cavity.
[0011] Furthermore, the pressure stabilizing chamber is provided with a fluid input valve connected to the fluid medium input end. The fluid input valve is located at the inlet of the pressure stabilizing chamber, and the fluid medium in the pressure stabilizing chamber flows into the cavity in the pressure stabilizing chamber through the fluid input valve.
[0012] Furthermore, the outlet of the pressure stabilizing chamber is also provided with an external interface for connecting to an external pipeline.
[0013] Furthermore, a sealing element is provided between the pressure stabilizing chamber and the plunger rod, which is used to prevent the fluid medium in the pressure stabilizing chamber from flowing out of the pressure stabilizing chamber.
[0014] Furthermore, the viscosity of the fluid medium in the pressure stabilizing chamber is in the range of 6,000-500,000 centipoise; the pressure ratio between the gas medium and the fluid medium is in the range of 15:1-50:1.
[0015] The beneficial effects of the present invention are: the pressure stabilizing system provided by the present invention can be widely used in automatic glue application systems, automatic coating systems and other chemical fluid pressure stabilizing and conveying systems; the pressure stabilizer in the pressure stabilizing system has a simple structure, is easy to disassemble and assemble, has low cost and wide applicability, and only needs to be connected to the gas medium and fluid medium output end to stabilize different fluid pressures as needed.

[0019] As shown in the figure, the present invention provides a voltage stabilization system, including a fluid channel for fluid medium flow and a voltage regulator for stabilizing the pressure of the fluid medium. The voltage regulator is provided with an inlet for fluid medium to flow in and an outlet for fluid medium to flow out. The fluid medium in the fluid channel flows into the voltage regulator from the inlet and flows out from the outlet of the voltage regulator.
[0020] In this embodiment, the pressure regulator includes a cylinder 1 filled with a gaseous medium and a pressure regulating chamber 2 for regulating the pressure of a fluid medium. The cylinder 1 has an inlet for the gaseous medium to enter and an outlet for the gaseous medium to exit. The pressure regulating chamber 2 has an inlet for the fluid medium to flow into and an outlet for the fluid medium to flow out. The pressure regulating chamber 2 is located at the bottom of the cylinder 1. A plunger assembly is disposed inside the cylinder 1, with the bottom of the plunger assembly extending into the pressure regulating chamber 2. The gaseous medium inside the cylinder 1 acts on the plunger assembly, and the plunger assembly regulates the pressure of the fluid medium in the pressure regulating chamber 2. The pressure regulator in the technical solution uses a gas medium with a pressure higher than atmospheric pressure as a power source. By adjusting the piston assembly, it stabilizes the outlet pressure of the fluid medium, reducing fluid pressure pulsations caused by the reversal of the adhesive or coating system. The fluid medium is mainly a high-viscosity corrosive fluid medium, such as paint, sealant, and chemical products. When pressure pulsations occur in the pressure stabilizing chamber, the pressure of the gas medium in the cylinder is changed, which in turn affects the movement of the piston assembly, thereby compensating for the fluid medium in the pressure stabilizing chamber. This reduces the pressure pulsations in the adhesive or coating hydraulic system and achieves the goal of stabilizing the hydraulic system.
[0021] In this embodiment, the plunger assembly includes a piston 3 and a plunger rod 4. The piston 3 is disposed within the cavity of the cylinder 1 and divides the cavity into an upper cavity and a lower cavity. The gas medium in the cylinder 1 fills the upper cavity, and the lower cavity is connected to atmospheric pressure. The plunger rod 4 is disposed within the lower cavity of the cylinder 1, and its upper end is fixedly connected to the piston 3. The lower end of the plunger rod 4 extends into the pressure stabilizing chamber 2 and acts on the fluid medium within the pressure stabilizing chamber 2. The gas medium is delivered into the upper cavity of the cylinder through an external air pump connected to the cylinder inlet and acts on the piston 3, while the fluid medium... The pressure regulator enters the pressure stabilizing chamber through the glue application or coating hydraulic system and acts on the plunger rod 4. This pressure regulator is suitable for pneumatic pumps with a ratio of 20:1 to 68:1 or electric pumps with a pressure of 10MPa to 40MPa. The maximum inlet pressure should be less than 0.6MPa, and pressure pulsation can be reduced by 60%. When pressure pulsation occurs in the hydraulic system, the piston 3 pushes the plunger rod 4 to move and compensate for the liquid, thereby reducing the pressure pulsation of the glue application or coating hydraulic system and achieving the purpose of stabilizing the hydraulic system. At the same time, since the piston assembly in contact with the fluid medium has a certain degree of corrosion resistance, this pressure regulator has a longer service life.
[0022] In this embodiment, the cylinder 1 is equipped with a gas medium input valve 5 connected to the air inlet and a gas medium output valve 9 connected to the air outlet. The gas medium is input into the upper cavity of the cylinder 1 through the gas medium input valve 5 and output through the gas medium output valve 9. The upper cavity of the cylinder 1 is respectively provided with a gas medium inlet and a gas medium outlet. The gas medium input valve 5 is provided at the gas medium inlet and the gas medium output valve 9 is provided at the gas medium outlet to control the gas medium pressure.
[0023] In this embodiment, a pressure regulating valve 6 is also provided at the cylinder inlet. The pressure regulating valve 6 is used to regulate the pressure of the gas medium in the upper cavity. By providing a pressure regulating valve 6 for pressure control at the cylinder inlet, the pressure of the gas medium in the cylinder can be controlled, and the pressure of the gas medium in the cylinder can be adjusted according to specific usage requirements.
[0024] In this embodiment, the pressure stabilizing chamber 2 is provided with a fluid input valve 7 connected to the external fluid medium input end, and the fluid medium in the pressure stabilizing chamber 2 flows into the pressure stabilizing chamber 2 through the fluid input valve 7.
[0025] In this embodiment, the pressure stabilizing chamber is also provided with an external interface 10 for connecting to an external pipeline; the external interface 10 is connected to an external pipeline or equipment as the output end of the fluid medium in the pressure stabilizing chamber, thereby continuously outputting a stable and constant pressure fluid medium to the outside. At the same time, the external interface 10 and the fluid input valve 7 can be interchanged according to the usage, depending on the direction of fluid medium delivery.
[0026] In this embodiment, a sealing element 8 is also provided between the pressure stabilizing chamber 2 and the plunger rod 4. The sealing element 8 is used to prevent the fluid medium in the pressure stabilizing chamber 2 from flowing out of the pressure stabilizing chamber 2. By providing the sealing element 8, the fluid medium in the pressure stabilizing chamber can be effectively prevented from flowing into the cylinder.
[0027] In this embodiment, the viscosity range of the fluid medium in the pressure stabilizing chamber 2 is 6000-500000 centipoise. Using a fluid medium with a viscosity range of 6000-500000 centipoise in this pressure regulator can effectively reduce the possibility of pressure pulsation in the pressure stabilizing chamber, and at the same time better suit the pressure regulator for pressure regulation. The pressure ratio formed between the gas medium and the fluid medium is 15:1-50:1. Since the contact area between the piston 3 and the gas medium is larger than the contact area between the plunger rod 4 and the fluid medium, a pressure ratio of 15:1-50:1 is formed. Therefore, by adjusting the pressure of the gas medium in the cylinder, the pressure of the gas part and the hydraulic part can be balanced by using the piston assembly.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
