Description

Technical Field

[0001] This utility model relates to the field of exhaust valve technology, and in particular to a ball basket that is designed to prevent blow-blocking by removing the float. Background Technology

[0002] Air venting valves, used in liquid pipelines, are valves that can promptly discharge gas generated within the pipeline and replenish air when negative pressure occurs. The basic structure and calculation method of air venting valves can be derived from GB / T36523-2018, but the standard's air venting valves have the following shortcomings: In existing air venting valve structures, the movable valve core and float are located inside a basket. When venting occurs, the float and movable valve core fall to the bottom of the basket under gravity, opening the air venting valve. After venting, the float and movable valve core rise due to water buoyancy, pressing against the sealing ring of the air venting valve and closing it. However, the manufacturing of the float is standardized, and its thickness cannot be arbitrarily changed. When the pressure inside the pipeline is too high, the hollow float may be flattened by the water pressure, potentially causing a decrease in buoyancy or even preventing the float from floating, affecting drainage within the basket. Secondly, it may cause the air venting valve to lose its anti-blowing capability. Thirdly, if an integrated composite air venting valve is used, it may lead to micro-venting seal failure. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] Based on this, this utility model proposes an anti-blow-blocking ball basket that removes the float ball, in order to solve the problem that the float ball will be flattened and affect the performance of the air vent valve when the water pressure is too high.

[0005] (II) Technical Solution

[0006] To overcome or at least partially solve the above problems, this utility model provides a ball basket with a float removed for preventing blow-blocking. The ball basket body has a first through hole at its bottom, a wind deflector fixed below the first through hole, a channel between the wind deflector and the ball basket body, multiple ball basket ribs that cooperate with a floating valve core fixed to the inner wall of the ball basket body, a baffle fixed to the lower end of each rib, and multiple second through holes at the upper end of the ball basket body, the diameter of each second through hole being larger than the diameter of the first through hole.

[0007] Preferably, the outer contour of the wind deflector is conical, the smaller end of the wind deflector is the lower end, and the wind deflector is coaxially arranged with the main body of the basketball hoop.

[0008] Preferably, the wind deflector is fixed to the main body of the basketball hoop by a connecting plate.

[0009] Preferably, one side of the connecting plate is fixed to the basketball hoop body by welding, and the other side is fixed to the edge of the wind deflector by welding.

[0010] Preferably, there are three connecting plates, which are evenly distributed on the outer side of the windbreak plate.

[0011] Preferably, the main body of the basketball hoop includes a basketball hoop tube and a basketball hoop bottom, and the basketball hoop reinforcement is fixed to the basketball hoop tube by welding.

[0012] Preferably, the thickness of the basket tube is greater than the thickness of the basket bottom, and the basket bottom is fixed to the basket tube by welding.

[0013] (III) Beneficial Effects

[0014] The anti-blowout basket of this utility model, which removes the float ball, has the following advantages:

[0015] In this invention, when the air pressure inside the pipe is high, the air inside the pipe is blocked by the baffle plate, and a large amount of air passes through the second through hole and then is discharged through the vent. Some air is buffered by the channel before entering the first through hole. The airflow blowing towards the floating valve core through the first through hole is weakened, preventing the floating valve core from being blown up and sealing the vent before the air pressure reaches 0.09MPa. The overall structure is simple, eliminating the float ball and avoiding the adverse effects of the float ball being flattened under high pressure. Secondly, the baffle plate is easier to manufacture and has lower processing costs than the float ball, which helps to reduce manufacturing costs. Attached Figure Description

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] See attached document Figure 1 and attached Figure 3 This embodiment provides a blow-proof ball basket without a float, including a ball basket body 1, which is fixed inside a valve body. The valve body is mounted on a pipe, and the valve body has an air hole above the ball basket body 1. The bottom of the ball basket body 1 has a first through hole 100. A baffle plate 2 is fixed below the first through hole 100, and a channel 200 is provided between the baffle plate 2 and the ball basket body 1. The valve body communicates with the first through hole 100 through the channel 200. Multiple ball basket ribs 3 are fixed on the inner wall of the ball basket body 1 to cooperate with the floating valve core. The floating valve core can move freely up and down along the ball basket ribs 3. The upper end of the ball basket body 1 has multiple second through holes 300, the diameter of which is larger than the diameter of the first through hole 100. Specifically, the area of ​​the second through hole 300 is larger than the nominal diameter area of ​​the ball basket. When the pipeline is filled with water, the air pressure inside the pipeline is high. A large amount of air passes through the second through-hole 300 and is then discharged through the vent. However, a small portion of the air is blocked by the baffle plate 2 and enters the first through-hole 100 through the channel 200 before being discharged through the vent. During this process, due to the baffle plate 2, the air inside the pipeline cannot be directly blown into the first through-hole 100. Instead, it needs to be buffered by the channel 200 before entering the first through-hole 100, which weakens the airflow inside the first through-hole 100 and prevents the floating valve core from being blown up and sealing the vent before the air pressure reaches 0.09MPa. When the air in the pipeline is almost completely discharged, the water level in the valve body rises and enters the ball basket body 1. The floating valve core floats up and seals the vent, thus stopping the discharge. During normal water transport, gases mixed in with and released from the water accumulate on the upper part of the valve body. When the gas volume increases to a certain value, the water level inside the valve drops, and the floating valve core moves away from the vent under gravity, allowing the gas to escape. After the gas is released, the pressure drops, the water level inside the valve rises, and the floating valve core floats up under buoyancy to reseal the vent. When negative pressure occurs in the pipeline, the floating valve core falls under the pressure difference and gravity, opening the vent to promptly replenish a large amount of gas, maintaining the normal pressure of the pipeline and thus protecting it. This invention has a simple overall structure, eliminating the float ball and avoiding the adverse effects of the float ball being flattened under high pressure. Furthermore, the baffle plate 2 is easier to manufacture and has lower processing costs compared to the float ball.

[0024] In another embodiment of this utility model, the outer contour of the wind baffle 2 is conical, with the smaller end of the wind baffle 2 being the lower end. This design facilitates airflow guidance, directing a large amount of air in the duct to the second through hole 300 for discharge, thereby reducing the amount of air entering the channel 200. The wind baffle 2 is coaxially arranged with the basketball basket body 1.

[0025] One embodiment of fixing the wind deflector 2: The wind deflector 2 is fixed to the main body 1 of the basketball basket by a connecting plate 5.

[0026] In another embodiment of this utility model, one side of the connecting plate 5 is fixed to the basketball basket body 1 by welding, and the other side is fixed to the edge of the wind deflector 2 by welding. One end of the connecting plate 5 extends into the channel 200, and the other end extends out of the channel 200. This structural design facilitates welding.

[0027] Specifically, there are three connecting plates 5, which are evenly distributed on the outside of the windbreak plate 2.

[0028] As another embodiment of the present invention: the main body 1 of the basketball basket includes a basketball basket tube 11 and a basketball basket bottom 12, and the basketball basket ribs 3 are fixed to the basketball basket tube 11 by welding.

[0029] As another embodiment of this utility model: refer to the appendix Figure 2 A baffle 4 is fixed at the lower end of the basket reinforcement 3, and the floating valve core falls down along the basket reinforcement 3 onto the baffle 4.

[0030] Specifically, the basket reinforcement 3, while serving as a guide, also ensures that there is a certain gap between the floating valve core and the basket reinforcement 3, so that water can be injected into the basket body 1.

[0031] In another embodiment of this utility model, the thickness of the basket tube 11 is greater than the thickness of the basket bottom 112, and the basket bottom 12 is fixed to the basket tube 11 by welding.

[0032] Finally, the method of this utility model is only a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.

[0033] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
