Description

Technical Field

[0001] This invention relates to the field of photovoltaic adhesive application technology, and in particular to an ultra-high pressure manually adjustable pressure regulator valve for applying adhesive to photovoltaic frames. Background Technology

[0002] A pressure regulating valve is a valve that adjusts the pressure of the inlet fluid to regulate the pressure of the outlet fluid, thereby automatically and stably maintaining the outlet fluid pressure at a certain value. It is widely used not only in high-rise buildings, areas with excessively high water pressure in urban water supply networks, mines, and other applications, but also in industries such as petroleum, chemicals, coatings, and greases for transporting high-viscosity fluids.

[0003] As the country places increasingly higher demands on environmental protection, clean energy is playing an increasingly important role, with fields such as wind power and solar power experiencing rapid development. Among these, solar power, due to its inexhaustible energy source, has received significant attention from the power generation industry. Besides solar energy itself, the most crucial element in the solar power industry is the photovoltaic module.

[0004] Photovoltaic modules typically consist of a laminate, a junction box, and a frame. In practical applications, the frame is installed around the laminate, and a sealant is used between the frame and the laminate to enhance sealing. During photovoltaic module production, frame and junction box sealant application machines are used to apply sealant to the frame and junction box respectively. When applying sealant to large components like photovoltaic modules, a large amount of sealant is required, and the flow rate of sealant output from the self-supplying unit is high, which can easily lead to unstable final sealant pressure and output. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an ultra-high pressure manual adjustment valve for applying adhesive to photovoltaic frames. This manual adjustment valve can realize adaptive adjustment of the concentricity between the adjustment block and the top rod, ensuring the uniformity and stability of the force at each point, thereby improving the balance and stability of the fluid pressure at the outlet.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: an ultra-high pressure manually adjustable pressure regulating valve for applying adhesive to photovoltaic frames, comprising: a base respectively provided with an inlet and an outlet, a guide seat sealed to the upper end of the base and forming an upper cavity therebetween with the guide seat, a support seat sealed to the lower end of the base and forming a lower cavity therebetween with the support seat, a first mounting seat provided in the upper cavity, and a second mounting seat provided in the lower cavity, wherein the first mounting seat and the second mounting seat, both of which can move in the vertical direction, are connected by a connecting rod passing through the base;

[0007] The upper end of the guide seat is threadedly connected to an adjusting seat, forming an adjusting chamber between the guide seat and the adjusting seat. The lower end of a vertically extending push rod is connected to a first mounting seat. The upper end of the push rod, which slides with the guide seat, extends into the adjusting chamber and is connected to an adjusting block. An elastic element in a compressed state is provided between the adjusting block and the adjusting seat.

When the liquid inlet is not in the liquid inlet state, the plug is sealed with the outlet at the lower end of the liquid inlet channel. An outlet channel is provided on the base, on the side of the liquid inlet channel opposite to the liquid inlet port, connecting the lower cavity and the outlet.

[0011] 2. In the above scheme, a connecting nozzle is installed at the lower part of the liquid inlet channel. The tube part of the connecting nozzle is embedded in the liquid inlet channel. The outer surface of the annular part of the connecting nozzle, which is located below the tube part and has an inner diameter larger than the tube part, is provided with a plurality of liquid outlet holes. The plug includes: a main body that can be slidably embedded in the annular part, a ball head formed in the center of the upper surface of the main body and embedded in the tube part, and a cylindrical part extending downward from the center of the lower surface of the main body. The upper surface of the main body has an annular groove around the ball head. The cylindrical part is embedded in a mounting hole opened in the upper surface of the second mounting base and is clearance-fitted with the inner wall of the mounting hole. The main body has a radially outward flange located below the connecting nozzle. The lower surface of the flange is in contact with the upper surface of the second mounting base.

[0018] 9. In the above scheme, the upper end of the liquid outlet channel, which is connected to the lower cavity, is connected to the upper cavity.

[0019] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0020] 1. This invention relates to an ultra-high pressure manually adjustable pressure regulating valve for applying adhesive to photovoltaic frames. The upper end of a guide seat is threadedly connected to an adjusting seat, forming an adjusting chamber between the guide seat and the adjusting valve. The lower end of a vertically extending push rod is connected to a first mounting base. The upper end of the push rod, which slides with the guide seat, extends into the adjusting chamber and engages with an adjusting block. An elastic element in a compressed state is provided between the adjusting block and the adjusting seat. The upper end of the adjusting block is embedded in the central through hole of the elastic element. The lower end of the adjusting block has a radially outward flange. The upper surface of the flange is in contact with the lower end face of the elastic element. A downward-facing conical groove is formed in the center of the lower surface of the adjusting block. The upper end of the push rod has a conical part matching the inner wall of the conical groove, which is correspondingly embedded in the conical groove on the adjusting block. A clearance groove communicating with the conical groove is formed on the adjusting block, located directly above the conical groove. A liquid inlet channel is provided in the base, and the upper end of the push rod is connected to the liquid inlet. The lower end of the inlet channel is connected to the lower cavity. A plug is installed on the second mounting seat inside the lower cavity, near the inlet channel. A compressed spring is vertically installed between the other side of the second mounting seat and the support seat. This allows the fluid entering from the inlet at a certain pressure to flow through the inlet channel and the lower cavity in sequence, and then be output from the outlet at a lower pressure. This improves the balance and stability of the output fluid pressure. At the same time, the length of the regulating chamber can be adjusted by rotating the guide seat, thereby adjusting the compression state of the elastic element and ultimately adjusting the spring tension. This allows for the regulation of the fluid pressure at the outlet after pressure reduction and stabilization, further meeting the needs for fluid pressure regulation and ensuring the consistency and stability of the fluid pressure at the outlet. Furthermore, during the adjustment process, the concentricity between the adjusting block and the push rod can be adaptively adjusted to ensure the uniformity and stability of the force applied at each point, thereby improving the balance and stability of the fluid pressure at the outlet.

[0021] 2. The ultra-high pressure manually adjustable pressure regulating valve for applying adhesive to photovoltaic frames of the present invention further comprises a connecting nozzle installed at the lower part of the liquid inlet channel. The tube body of the connecting nozzle is embedded in the liquid inlet channel. The annular portion of the connecting nozzle, located below the tube body and with an inner diameter larger than the tube body, has several liquid outlet holes on its outer surface. The plug comprises: a main body that can be slidably embedded in the annular portion, a ball head formed in the center of the upper surface of the main body and embedded in the tube body, and a cylindrical portion extending downward from the center of the lower surface of the main body. The upper surface of the main body has an annular groove around the ball head. The cylindrical portion is embedded in a mounting hole on the upper surface of the second mounting base and has a clearance fit with the inner wall of the mounting hole. The main body has a radially outward flange located below the connecting nozzle. The lower surface of the flange is in contact with the upper surface of the second mounting base. When not in the liquid-inlet state, the ball head of the plug and the tube body of the connecting nozzle, through the opening and closing of the ball head on the plug and the tube body of the connecting nozzle, allow the fluid entering from the liquid inlet at a certain pressure to flow sequentially through the liquid inlet channel and the lower cavity, and then be output from the liquid outlet at a lower pressure. This can improve the balance and stability of the output fluid pressure. Furthermore, by setting the plug to float, adaptive coaxial adjustment between the reciprocating extension and retraction of the plug and the liquid inlet channel can be achieved, avoiding force disturbance caused by plug eccentricity. This can not only improve the service life of the component, but also further ensure the balance and stability of fluid pressure regulation. The ball head on the plug and the annular groove opened around the ball head can further equalize and depressurize the flowing fluid, thereby improving the balance and stability of the fluid pressure at the liquid outlet.

[0062] Each of the above-mentioned sealing rings 171 has a retaining ring 172 on its upper and lower sides.

[0063] The working principle of this invention is as follows:

[0064] The force exerted on the spring by the second mounting seat is adjusted by adjusting the push rod, thereby adjusting the reverse tension of the spring.

[0065] When the inlet pressure is less than the spring tension, the plug and the outlet at the lower end of the inlet channel remain sealed. When the adjusted spring tension is less than the inlet pressure, the fluid entering from the inlet drives the plug to move towards the spring, forming a fluid channel between the plug and the inlet channel, allowing the fluid to enter the lower cavity. During this process, the fluid pressure is reduced and equalized and stabilized in the lower cavity, and finally output from the outlet.

[0066] Furthermore, by connecting the upper and lower chambers through the liquid outlet channel, the buffer space of the fluid after depressurization is increased, thereby further improving the balance and stability of the fluid pressure output from the liquid outlet while depressurizing.

[0067] The aforementioned manually adjustable pressure regulating valve allows fluid entering at a certain pressure through the inlet to flow sequentially through the inlet channel and lower chamber before being output from the outlet at a lower pressure. This improves the balance and stability of the output fluid pressure. Furthermore, by rotating the guide seat, the length of the regulating chamber can be adjusted, thereby regulating the compression state of the elastic element and ultimately the elastic tension of the spring. This allows for the regulation of the fluid pressure at the outlet after pressure reduction and stabilization, further meeting the needs for fluid pressure regulation and ensuring the consistency and stability of the fluid pressure at the outlet. During the adjustment process, the concentricity between the adjusting block and the push rod can be adaptively adjusted to ensure uniform and stable forces at all points, further improving the balance and stability of the fluid pressure at the outlet.

[0068] Furthermore, by opening and closing the ball head on the plug and the tube body of the connecting nozzle, the fluid entering from the inlet at a certain pressure flows sequentially through the inlet channel and the lower cavity before being output from the outlet at a lower pressure. This improves the balance and stability of the output fluid pressure. The floating design of the plug allows for adaptive coaxial adjustment between the reciprocating plug and the inlet channel, preventing force disturbances caused by plug eccentricity. This not only extends the component's lifespan but also further ensures the balance and stability of fluid pressure regulation. The ball head on the plug and the annular groove around it further equalize and depressurize the flowing fluid, thereby improving the balance and stability of the fluid pressure at the outlet.
