Description

Technical Field

[0001] This utility model relates to the field of exhaust valve technology, and in particular to a fully automatic exhaust valve that can be equipped with a 360-degree rotating air guide pipe. Background Technology

[0002] An air release valve, also known as a vent valve, is a valve installed in a piping system to release excess gas from inside the pipes. Its working principle is that when the internal pressure of the pipe exceeds a set value, the air release valve automatically opens, releasing the internal gas and restoring the system pressure to balance.

[0003] In the existing technology, the angle of the air guide pipe of the fully automatic exhaust valve cannot be adjusted after it is connected. Therefore, it can only be used by adjusting the fully automatic exhaust valve, which is inconvenient during installation. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing fully automatic exhaust valve, the angle of the air guide tube cannot be adjusted after connection, making installation and use inconvenient as it can only be done by adjusting the fully automatic exhaust valve. The invention proposes a fully automatic exhaust valve with a 360-degree rotating air guide tube.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic exhaust valve capable of mounting a 360-degree rotating air guide pipe, comprising a valve body mechanism, wherein the valve body mechanism includes a fully automatic exhaust valve body, an exhaust nozzle is fixedly connected to the upper end of the fully automatic exhaust valve body, an air guide pipe assembly mechanism is provided above the exhaust nozzle, the air guide pipe assembly mechanism includes a hexagonal nut, the hexagonal nut is threadedly connected to the exhaust nozzle, an inner sliding cavity is provided in the upper middle part of the hexagonal nut, a bottom sliding sleeve is slidably connected inside the inner sliding cavity, a bent tube is fixedly connected to the upper end of the bottom sliding sleeve, the bent tube is slidably connected to the hexagonal nut, an inner limiting sleeve is threadedly connected inside the hexagonal nut, and a spring is provided between the inner limiting sleeve and the bottom sliding sleeve.

[0006] Preferably, a second sealing gasket is provided at the upper end of the bottom sliding sleeve, and an air guide pipe is installed at one end of the bent tube.

[0007] Preferably, a No. 1 connection port is fixedly connected to the lower end of the fully automatic exhaust valve body, and a No. 1 sealing gasket is provided at the upper end of the fully automatic exhaust valve body and on the outside of the exhaust nozzle.

[0008] Preferably, the exhaust nozzle has an internal threaded groove extending through its center.

[0009] Preferably, the internal thread of the internal threaded groove is connected to an adjusting valve cap, and threaded holes are provided on both sides of the middle part of the upper end of the adjusting valve cap.

[0010] Preferably, both of the threaded holes are internally threaded with threaded rods.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the bottom sliding sleeve and spring allow the bent tube to rotate within the hexagonal nut. This fixes the position of the fully automatic exhaust valve body, and then the bent tube can be rotated to adjust the pipe connection position, making it convenient to use. This design allows for 360° rotation without dead angles, making it convenient and quick to use. By rotating the inner limiting sleeve and spring, the position of the inner limiting sleeve can be adjusted to adjust the force of the spring pressing the bottom sliding sleeve, thereby adjusting the sealing effect. At the same time, the force required for the bent tube to rotate can be adjusted, increasing the stability during use.

[0013] 2. In this utility model, by setting the threaded hole and the inner limiting sleeve, after rotating the adjusting valve cap to adjust the exhaust volume, the bottom of the threaded rod can be rotated to contact the upper end of the exhaust nozzle for support, which can ensure the airflow and avoid obstructing the airflow. Compared with the rubber pad support adjustment, it is more convenient to use and can be adjusted steplessly. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a fully automatic exhaust valve that can be fitted with a 360-degree rotating air guide tube. It includes a valve body mechanism 1, which comprises a fully automatic exhaust valve body 11. An exhaust nozzle 13 is fixedly connected to the upper end of the fully automatic exhaust valve body 11. An air guide tube assembly mechanism 2 is provided above the exhaust nozzle 13. The air guide tube assembly mechanism 2 includes a hexagonal nut 21, which is threadedly connected to the exhaust nozzle 13. An inner sliding cavity 26 is formed in the upper center of the hexagonal nut 21. A bottom sliding sleeve 24 is slidably connected inside the inner sliding cavity 26. The upper end of the bottom sliding sleeve 24 is fixed... A bent tube 23 is connected, and the bent tube 23 is slidably connected to a hexagonal nut 21. The internal thread of the hexagonal nut 21 is connected to an inner limiting sleeve 211. A spring 25 is provided between the inner limiting sleeve 211 and the bottom sliding sleeve 24. The diameter of the lower end thread of the hexagonal nut 21 is larger than the diameter of the bent tube 23, and the bending radius of the bent tube is larger than the height of the hexagonal nut 21. The interior of the fully automatic exhaust valve body 11 includes a float structure, a sealing component, an exhaust / intake channel, a drive mechanism, and a buffer mechanism. The exhaust channel is connected to the exhaust nozzle 13, and the intake channel is connected to the first connection port 12.

[0024] The specific settings and functions of this embodiment are described in detail below. The bottom sliding sleeve 24 and spring 25 allow the bent tube 23 to rotate within the hexagonal nut 21. This fixes the position of the fully automatic exhaust valve body 11, allowing the bent tube 23 to be rotated to adjust the pipe connection position, making it convenient to use. This design allows for 360° rotation without dead angles, making it quick and easy to use. The inner limiting sleeve 211 and spring 25 allow the inner limiting sleeve 211 to rise or fall within the hexagonal nut by rotation. Due to the inconvenient position of the bottom sliding sleeve 24, the degree of compression of the spring 25 changes, adjusting the force of the spring 25 compressing the bottom sliding sleeve 24 and regulating the sealing effect. Simultaneously, the force required to rotate the bent tube 23 can be adjusted, increasing stability during use. The bottom of the inner limiting sleeve 211 has a groove for connecting with a flathead screwdriver for adjustment.

[0025] Example 2: Figures 1-4 As shown, a second sealing gasket 27 is provided at the upper end of the bottom sliding sleeve 24, a vent pipe 22 is installed at one end of the bent pipe 23, a first connection port 12 is fixedly connected to the lower end of the fully automatic exhaust valve body 11, a first sealing gasket 15 is provided at the upper end of the fully automatic exhaust valve body 11 and outside the exhaust nozzle 13, an internal thread groove 14 is provided through the middle of the exhaust nozzle 13, an adjusting valve cap 28 is connected to the internal thread of the internal thread groove 14, threaded holes 29 are provided on both sides of the middle of the upper end of the adjusting valve cap 28, and threaded rods 210 are threadedly connected to the inside of the two threaded holes 29, and a slot is provided at the top of the threaded rod 210 for rotation adjustment using a flathead screwdriver.

[0026] The overall effect of this embodiment is that, through the setting of the threaded hole 29 and the inner limiting sleeve 211, after rotating the adjusting valve cap 28 to adjust the exhaust volume, the bottom of the threaded rod 210 can be rotated to contact the upper end of the exhaust nozzle 13 for support, which can ensure the flow of air and avoid obstructing the flow of air. Compared with the adjustment of rubber pad support, it is more convenient to use and can be adjusted steplessly.

[0027] The usage and working principle of this device are as follows: When in use, adjust the connection distance between the regulating valve cap 28 and the internal thread groove 14 according to the requirements to adjust the gas outflow, which is the exhaust speed. Rotate the threaded rod 210 until the bottom of the threaded rod 210 contacts the upper end of the exhaust nozzle 13. Rotate the inner limiting sleeve 211 to adjust the squeezing force of the spring 25 on the bottom sliding sleeve 24. Then connect the hexagonal nut 21 to the exhaust nozzle 13. Install the fully automatic exhaust valve body 11 in a suitable position. Process the air guide pipe 22 and install it with the required pipeline. During this process, the bending pipe 23 can be rotated to adjust the rotation angle.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
