Description

Technical Field

[0001] This utility model relates to the field of pipeline exhaust valve technology, and more specifically, to an exhaust valve with pressure regulation function. Background Technology

[0002] Existing air release valves are divided into three types: full-pressure high-speed air release valve, single-port air release valve, high-speed air release valve, and a combination of the two types, called a double-port air release valve. Air release valves are generally installed on pressurized water supply pipelines buried underground. Their function is to release gas in the pipeline to prevent pipeline gas explosion. Generally speaking, water contains about some dissolved air. As the water flows, this air will be released from the water. For example, in a water conveyance system composed of pumps and pipelines, water flows in the pipeline under the action of the pump, so the air in the water is continuously released and accumulates at a high position, forming an air pocket, making water conveyance difficult, and the water conveyance capacity of the water conveyance system may be reduced as a result.

[0003] However, traditional air vents release gas by causing water pressure in the pipe to rise and enter the air vent, which then lifts the float to open the air vent. Because the existing technology does not have a structure to control the pressure of the float rising, even a slight increase in water pressure in the pipe will cause the water flow to lift the float, resulting in insufficient water pressure to be retained in the pipe. Consequently, the water pressure delivered in the pipe is too low, affecting the water delivery efficiency.

[0004] To address the aforementioned technical shortcomings, a solution is provided. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides an exhaust valve with pressure regulation function. By setting a top pressure mechanism, a structure for controlling the pressure of the float ball is set on the top of the exhaust valve. The float ball is compressed and pressurized, meaning that the float ball will only float when the water pressure in the pipeline reaches a certain level. This can both alleviate the retention of gas in the pipeline and maintain a certain water pressure in the pipeline, avoiding affecting the water delivery effect of the pipeline, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an exhaust valve with pressure regulation function, including a connecting pipe, the top of which is connected to an exhaust valve groove, a float ball is provided inside the exhaust valve groove, a lifting rod is fixedly installed on one side of the float ball, the lifting rod is hinged to the inner wall of the exhaust valve groove, an exhaust valve port is provided at the top of the exhaust valve groove, and a pressing mechanism is provided at the top of the lifting rod.

[0007] The top-pressing mechanism includes a slider that is slidably mounted on the outer wall of the lifting rod. A top-pressing rod is hinged to the top of the slider. The top-pressing rod is set in a vertical position. A base plate is fixedly mounted on the top of the top-pressing rod. A sleeve is sleeved on the outer wall of the base plate. The sleeve is fixedly mounted on the inner wall of the exhaust valve groove.

[0008] In a preferred embodiment, a limit spring is fixedly installed on the top of the base plate, and a pressing plate is fixedly installed on the top of the limit spring. The pressing plate is slidably installed on the inner wall of the sleeve, and the pressing plate is arranged in a horizontal state. The outer wall of the pressing plate is in contact with the inner wall of the sleeve.

[0009] In a preferred embodiment, a threaded rod is rotatably mounted on the top of the extrusion plate. The threaded rod is threadedly connected to the outer wall of the exhaust valve groove. A turntable is fixedly mounted on the top of the threaded rod, and the turntable is set in a horizontal position.

[0010] In a preferred embodiment, the top of the turntable is provided with a release mechanism, which includes a slot formed in the inner wall of the turntable and the threaded rod. A pull rope is provided inside the slot. The pull rope is fixedly installed on the top of the base plate. The pull rope extends through the slot and out of the top of the turntable. A horizontal tie rod is fixedly installed on the top of the pull rope. The horizontal tie rod is set in a horizontal position.

[0011] In a preferred embodiment, a pull ring is rotatably mounted on one side of the horizontal tie rod. The pull ring is horizontally positioned. A clamp block is provided on one side of the pull ring. The clamp block is fixedly mounted on the outer wall of the turntable and is vertically positioned. The clamp block and the pull ring are arranged correspondingly to each other.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by setting up a top-pressing mechanism, drives the threaded rod to rotate synchronously by rotating the turntable, thereby moving the pressing plate. The pressing plate moves down and presses down the limiting spring. The limiting spring is compressed and deformed, generating elastic force to squeeze the bottom plate. The bottom plate is subjected to force and presses down the top-pressing rod under the sleeve. In turn, the top-pressing rod presses down on the slider, which in turn presses down on the lifting rod. That is, the lifting rod counteracts the pressure when the float moves upward under force. Thus, the float will only move upward when the water pressure reaches a certain level. This can both alleviate the problem of gas retention in the pipeline and maintain a certain water pressure in the pipeline, avoiding affecting the water delivery effect of the pipeline.

[0014] 2. This utility model, by setting up a release mechanism, allows for the direct pulling of the pull ring to move backward and lock onto the clamp block when there is no need for pressure and gas to remain in the pipeline. This pulls the horizontal pull rod to lift the pull rope, which in turn pulls the bottom plate upward. The bottom plate then drives the top pressure rod and the slider, which in turn drives the lifting rod to move upward. The lifting rod can then directly open the exhaust valve port for direct exhaust. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Refer to the instruction manual appendix Figure 1 - Figure 5 An exhaust valve with pressure regulating function, such as Figure 1 and Figure 3 As shown, it includes a connecting pipe 1, the top of the connecting pipe 1 is connected to an exhaust valve groove 2, a float 3 is provided inside the exhaust valve groove 2, a lifting rod 4 is fixedly installed on one side of the float 3, the lifting rod 4 is hinged to the inner wall of the exhaust valve groove 2, an exhaust valve port 5 is provided at the top of the exhaust valve groove 2, and a pressing mechanism 6 is provided at the top of the lifting rod 4.

[0023] like Figure 3 and Figure 4As shown, the top-pressing mechanism 6 includes a slider 61 slidably mounted on the outer wall of the lifting rod 4. A top-pressing rod 62 is hinged to the top of the slider 61. The top-pressing rod 62 is set in a vertical position. A base plate 63 is fixedly mounted on the top of the top-pressing rod 62. A sleeve 64 is sleeved on the outer wall of the base plate 63. The sleeve 64 is fixedly mounted on the inner wall of the exhaust valve groove 2. The top-pressing rod 62 is pressed down by the sleeve 64 under the force of the base plate 63, and then the top-pressing rod 62 presses down on the slider 61. Thus, the slider 61 presses down on the lifting rod 4. That is, the lifting rod 4 counteracts the pressure when the float 3 moves upward under force. Therefore, the float 3 will only move upward when the water pressure reaches a certain level.

[0024] like Figure 3 and Figure 4 As shown, a limit spring 65 is fixedly installed on the top of the base plate 63, and a compression plate 66 is fixedly installed on the top of the limit spring 65. The compression plate 66 is slidably installed on the inner wall of the sleeve 64. The compression plate 66 is set in a horizontal state, and the outer wall of the compression plate 66 is in contact with the inner wall of the sleeve 64. By moving the compression plate 66 downward, the limit spring 65 is compressed and deformed, and an elastic force is generated to squeeze the base plate 63.

[0025] like Figure 3 and Figure 4 As shown, a threaded rod 67 is rotatably mounted on the top of the extrusion plate 66. The threaded rod 67 is threadedly connected to the outer wall of the exhaust valve groove 2. A turntable 68 is fixedly mounted on the top of the threaded rod 67. The turntable 68 is set in a horizontal state. By rotating the turntable 68, the threaded rod 67 is driven to rotate synchronously, thereby driving the extrusion plate 66 to move.

[0026] like Figure 3 and Figure 5 As shown, a release mechanism 7 is provided on the top of the turntable 68. The release mechanism 7 includes slots formed in the inner walls of the turntable 68 and the threaded rod 67. A pull rope 71 is provided inside the slots. The pull rope 71 is fixedly installed on the top of the base plate 63. The pull rope 71 passes through the slots and extends out of the top of the turntable 68. A horizontal pull rod 72 is fixedly installed on the top of the pull rope 71. The horizontal pull rod 72 is set in a horizontal state. The pull of the horizontal pull rod 72 pulls up the pull rope 71, that is, the pull rope 71 pulls the base plate 63 upward. As a result, the base plate 63 drives the top pressure rod 62 and the slider 61 and drives the lifting rod 4 upward. The lifting rod 4 can then directly open the exhaust valve port 5 for direct exhaust.

[0027] like Figure 3 and Figure 5As shown, a pull ring 73 is rotatably installed on one side of the horizontal tie rod 72. The pull ring 73 is set in a horizontal state. A clamp block 74 is provided on one side of the pull ring 73. The clamp block 74 is fixedly installed on the outer wall of the turntable 68 and is set in a vertical state. The clamp block 74 and the pull ring 73 are set in a corresponding position. By pulling the pull ring 73 backward and locking it on the clamp block 74, the horizontal tie rod 72 continuously pulls the pull rope 71 to retract the base plate 63 and drive the lifting rod 4, that is, the exhaust valve port 5 continuously maintains the exhaust state, which is convenient for continuously reducing pressure and gas when the pressure in the pipeline is not needed.

[0028] The working process and principle of this utility model are as follows:

[0029] Rotating the turntable 68 drives the threaded rod 67 to rotate synchronously, which in turn drives the pressing plate 66 to move. The pressing plate 66 moves down and presses down the limiting spring 65. The limiting spring 65 is compressed and deformed, generating elastic force to press the bottom plate 63. The bottom plate 63 is subjected to force and presses down the top rod 62 under the sleeve 64. In turn, the top rod 62 presses down the slider 61, and the slider 61 presses down the lifting rod 4. That is, the lifting rod 4 counteracts the pressure when the float 3 moves up under force. Therefore, the float 3 will only move up when the water pressure reaches a certain level. This can alleviate the problem of gas retention in the pipeline and maintain a certain water pressure in the pipeline, thus avoiding affecting the water delivery effect of the pipeline.

[0030] Meanwhile, when there is no need to retain pressure and gas in the pipeline, by directly pulling the pull ring 73 backward and locking it on the clamp block 74, the horizontal pull rod 72 is pulled up to lift the pull rope 71. That is, the pull rope 71 pulls the bottom plate 63 upward, so the bottom plate 63 drives the top pressure rod 62 and the slider 61 and drives the lifting rod 4 upward. The lifting rod 4 can then directly open the exhaust valve port 5 for direct exhaust.
