Technical Field

[0001] This utility model belongs to the field of valve technology and relates to a high-efficiency exhaust valve. Background Technology

[0002] The exhaust valve is usually equipped with a filter screen, which is mainly used to capture air bubbles and impurities mixed in the medium.

[0003] The existing exhaust valve has an unstable internal filter structure that is difficult to disassemble, making it unable to efficiently capture air bubbles and impurities mixed in the medium, resulting in low permeability and affecting its use. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a high-efficiency exhaust valve. This valve assembles a filter screen through a multi-layer radial winding method, resulting in a tightly packed, irregularly arranged structure at the filter screen openings, thereby improving permeability.

[0005] The objective of this utility model can be achieved through the following technical solution: A high-efficiency exhaust valve, comprising an exhaust cap assembly and a threaded cup body and a cup lid, characterized in that the cup body is movably connected with a three-way connector having an inlet end, an outlet end, and a connecting end; a cup cylinder is provided within the cup body, and a filter assembly is provided within the cup cylinder, consisting of a filter mesh winding skeleton and a filter mesh radially wound on the filter mesh winding skeleton, and the filter mesh is used to collect and remove air bubbles trapped in the medium and discharge them through the exhaust cap assembly; the cup lid, located above the cup cylinder, is provided with a filter mesh skeleton and filters distributed on the filter mesh skeleton. The filter assembly consists of several filter screens, which are used to collect and remove air bubbles trapped in the medium and discharge them through the exhaust cap assembly. The top of the filter screen winding skeleton has several exhaust holes, the bottom of the cup has several water outlet holes, and the cup has a water inlet on its peripheral wall. The three-way connector has a hollow water inlet sleeve, and the end of the hollow water inlet sleeve extends to the water inlet and divides the inside of the three-way connector into an inner cavity and an outer cavity. The inner cavity connects the water inlet end and the water inlet to form a water inlet channel, and the outer cavity connects the water outlet hole and the water outlet end to form a water outlet channel.

[0006] In the aforementioned high-efficiency exhaust valve, the filter screen winding skeleton has multiple skeleton support ribs.

[0007] In the aforementioned high-efficiency exhaust valve, the filter mesh frame is snapped into the cup lid.

[0008] In the aforementioned high-efficiency exhaust valve, the filter screen winding skeleton is limited and installed inside the cup.

[0009] In the aforementioned high-efficiency exhaust valve, the connecting end of the three-way connector has a union cap that is in contact with the cup body.

[0010] Compared with existing technologies, this high-efficiency exhaust valve has a dual bubble impurity collection filter screen. The filter screen is assembled by multi-layer radial winding, which makes the filter screen opening form a tight irregular arrangement structure, improving permeability. In addition, the internal filter screens can be disassembled for maintenance and cleaning, improving working efficiency. Attached Figure Description

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1-4As shown, this high-efficiency exhaust valve includes an exhaust cap assembly 3 and a threaded cup body 1 and a cup lid 2. The cup body 1 is fitted with a tee connector 7 with an inlet end 4, an outlet end 5, and a connecting end 6. A cup cylinder 8 is provided inside the cup body 1 for positioning. A stepped groove is formed inside the cup body 1, and the top of the cup cylinder 8 protrudes outward along its edge and is hung in the stepped groove. The tightened cup lid 2 presses and limits the cup cylinder 8 along its edge, facilitating disassembly of the cup cylinder 8. Inside the cup cylinder 8 is a filter assembly consisting of a filter screen winding frame 9 and filter screens 10 radially wound around the filter screen winding frame 9. Filter screens 10 collect and remove air bubbles trapped in the medium, which are then discharged through the exhaust cap assembly 3. Inside the cup lid 2, above the cup cylinder 8, is a filter assembly consisting of a filter screen frame 17 and several filter screens 18 distributed on the filter screen frame 17. Filter screens 18 collect and remove air bubbles trapped in the medium a second time, which are then discharged through the exhaust cap assembly 3. The top of the filter screen winding frame 9 has several vent holes 11, the bottom of the cup 8 has several water outlet holes 12, and the cup 8 has a water inlet 13 on its peripheral wall. The three-way connector 7 has a hollow water inlet sleeve 14. The end of the hollow water inlet sleeve 14 is sealed and extends to the water inlet 13, dividing the inside of the three-way connector 7 into an inner cavity and an outer cavity. The inner cavity connects the water inlet end 4 and the water inlet 13 to form a water inlet channel 15, and the outer cavity connects the water outlet hole 12 and the water outlet end 5 to form a water outlet channel 16. The medium enters from the water inlet end 4 and passes through the water inlet channel 15 and the water inlet 13 in sequence. Under the action of the filter screen 10, the medium air bubbles and impurities are collected once. Then, it passes through the filter screen 2 18 to form a secondary action and is released from the vent hole 11. Finally, the vent cap assembly 3 is used to vent the air (the vent cap assembly 3 is opened). At the same time, another part of the medium flows out from the water outlet hole 12 and is discharged through the water outlet channel 16 and the water outlet end 5.

[0018] To elaborate further, the filter screen winding frame 9 has multiple frame support ribs 19, and the filter screen is radially wound around the frame support ribs 19 to achieve a positioning effect.

[0019] To elaborate further, the filter frame 17 is snapped into the cup lid 2. The inner wall of the cup lid 2 has a stepped portion, and the filter frame 17 has multiple snap-fit ​​portions, which limit and snap onto the stepped portion.

[0020] To elaborate further, the filter mesh winding frame 9 is installed within the cup cylinder 8. The upper and lower ends of the filter mesh winding frame 9 are detachably installed within the cup cylinder 8. There are mounting positions at both the top and bottom of the cup cylinder 8, and the filter mesh winding frame 9 has mounting parts at both the top and bottom of these positions. As the cup cylinder 8 is disassembled, the filter mesh winding frame 9 can be removed, achieving the effect of disassembly, cleaning, and maintenance.

[0021] Preferably, the connecting end 6 of the tee connector 7 has a union cap 20 that is connected to the cup body 1.

[0022] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0023] Although this document frequently uses terms such as cup body 1, cup lid 2, vent cap assembly 3, water inlet end 4, water outlet end 5, connecting end 6, tee connector 7, cup cylinder 8, filter screen winding skeleton 9, filter screen one 10, vent hole 11, water outlet hole 12, water inlet 13, hollow water inlet sleeve 14, water inlet channel 15, water outlet channel 16, filter screen skeleton 17, filter screen two 18, skeleton support rib 19, and union cap 20, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
