Description

Technical Field

[0001] The invention relates to the technical field of pressure reducing valves, in particular to an adjustable pressure reducing valve with a filtering function. Background Art

[0002] The pressure reducing valve is an intelligent valve that uses the energy of the medium itself to adjust and control the pipeline pressure. It is used in domestic water supply, fire water supply and other industrial water supply systems. By adjusting the pressure reducing pilot valve of the regulating valve, the outlet pressure of the main valve can be adjusted. By changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction. However, most traditional pressure reducing valves do not have a special filter design. Even if they do, the filter screen is usually fixed inside the valve body. When cleaning or replacing, the entire valve body needs to be disassembled, which is complicated and time-consuming, which increases maintenance costs and reduces work efficiency.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-6 As shown, the present invention is an adjustable pressure reducing valve with a filtering function, comprising an upper valve body 1 and a filter tank 2, the bottom of the upper valve body 1 is connected with a sealing layer 3, the bottom of the sealing layer 3 is connected with a lower valve body 4, and a quick-release filtering mechanism 5 is arranged between the lower valve body 4 and the filter tank 2; the quick-release filtering mechanism 5 comprises a connecting plate 51 fixedly connected to the inner wall of the lower valve body 4, a filtering layer 52 fixedly connected to the top of the filter tank 2 and two connecting blocks 53 fixedly connected to the surface of the filter tank 2, the bottom of the connecting plate 51 is fixedly connected with two connecting strips 54, and the two connecting strips 54 are fixedly connected to the bottom of the connecting plate 51. The opposite side of the connecting strip 54 is fixedly connected with a connecting sleeve 55, the inner walls of the two connecting sleeves 55 are fixedly connected with a first spring rod 56, the opposite ends of the two first spring rods 56 are fixedly connected with a buckle ball 57, the top of the filter layer 52 is fixedly connected with a T-shaped buckle strip 58, and the inner walls of the two connecting blocks 53 are threadedly connected with a screw rod 59. Traditional equipment uses multiple screw rods 59 for connection, which is troublesome to disassemble and assemble. This design uses two screw rods 59 to cooperate with buckle connection, which can ensure the stability of the connection while ensuring fast disassembly and assembly. The bottom of the two screw rods 59 is fixedly connected with a twisting cover 510. By setting a quick-release filter mechanism 5, the filter screen can be easily disassembled and cleaned without disassembling the entire valve body, thereby reducing maintenance costs and improving work efficiency. The filter screen can be easily cleaned regularly to prevent blockage, maintain the flow capacity of the pressure reducing valve, and ensure the normal operation of the system.

[0027] A sealing hole 6 is opened at the top of the sealing layer 3, and a pressure-regulating sealing mechanism 7 is provided on the upper valve body 1. By providing the pressure-regulating sealing mechanism 7, the adaptation design of the sealing insert ring 77 and the inner wall of the sealing hole 6 can achieve a tighter docking when the pressure is adjusted to close, effectively preventing leakage and improving the sealing performance.

[0028] The pressure regulating sealing mechanism 7 includes a pressure regulating ring 71 rotatably connected to the inner wall of the upper valve body 1, the inner wall of the pressure regulating ring 71 is fixedly connected with a connecting rod 72, the top of the connecting rod 72 is fixedly connected with an adjusting disk 73, the surface of the connecting rod 72 is fixedly connected with a connecting disk 74, the connecting disk 74 is fixedly connected with a valve plate 76 through a second spring rod 75, and the bottom of the valve plate 76 is fixedly connected with a sealing insert ring 77.

[0029] The surface of the upper valve body 1 is provided with a pressure gauge 8, which displays the outlet pressure of the pressure reducing valve, so as to facilitate the user to adjust and monitor the pressure, and it is a prior art, and will not be described in detail in this article. The surface of the upper valve body 1 is connected with an inlet 9, which is connected to the external inlet pipe.

[0030] The surface of the lower valve body 4 is connected with an outlet 10, and the outlet 10 is connected with an external outlet pipe. The lower valve body 4 and the two screw rods 59 are threadedly connected.

[0031] The two buckle balls 57 are matched with the T-shaped buckle strip 58 , and a plurality of filter holes are formed on the filter layer 52 .

[0032] The sealing insert 77 is adapted to the sealing hole 6 and is made of rubber material, which has good elasticity and sealing properties and can effectively fill the tiny gap between the sealing insert 77 and the sealing hole 6, thereby achieving a good sealing effect. At the same time, the wear resistance and oil resistance of rubber also enable it to maintain stable performance in harsh working environments.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] The working principle of the present invention is as follows: first, push the filter tank 2 upward so that the T-shaped buckle strip 58 on the top filter layer 52 squeezes the two buckle balls 57 upward, and the two buckle balls 57 are retracted into the two connecting sleeves 55. When the T-shaped buckle strip 58 moves to abut against the connecting plate 51, the two buckle balls 57 are rebounded back to their original positions by the elastic characteristics of the two first spring rods 56, so that the two buckle balls 57 are embedded in the two matching notches on the T-shaped buckle strip 58, and the T-shaped buckle strip 58 is locked, so as to quickly achieve the preliminary locking of the filter layer 52 and the filter tank 2. Then, screw the two screw rods 59 and screw the cover 510, so that the two screw rods 59 lock the filter tank 2 and the lower valve body 4 more tightly together to increase stability (the reverse operation can achieve rapid disassembly). Then, turn the adjusting disk 73 by hand, so that the adjusting disk 73 drives the pressure regulating ring 71 to rotate in the inner wall of the upper valve body 1 through the connecting rod 72 to adjust the pressure. At the same time, the connecting disk 74 at the bottom squeezes the valve plate 76 to make the valve plate 76 move downward linearly, so that the sealing insert 77 is aligned and inserted into the sealing hole 6 to achieve sealing contact and close the valve port (conversely, turning the adjustment disk 73 can open it and increase the pressure). When the pressure is adjusted to a suitable level, the fluid enters from the inlet 9 and is discharged from the outlet 10, and is filtered to a certain extent by the filter layer 52.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
