Description

Technical Field

[0001] This application relates to the field of pipeline negative pressure suppressors, and particularly to a new type of horizontal pipeline negative pressure suppressor. Background Technique

[0002] A horizontal pipeline negative pressure suppressor is a water supply auxiliary device, especially designed to suppress the negative pressure phenomenon in pipelines. It mainly consists of a negative pressure suppressor housing, pipeline flanges, convex cavities, and main components such as a floating ball sealing device, exhaust channels, sliding rod supports, and floating balls inside the convex cavities. The advantage of this suppressor is that it uses the buoyancy of the floating ball itself as the main functional component, is sensitive to pressure changes in the pipe network, has a fast response speed, a simple structure, and good working stability. It uses the floating ball as the core component to directly respond to pressure changes in the pipe network, and achieves the effect of suppressing sound by changing the overflow mode of the propulsion gas or reducing the firing speed of the warhead, thereby effectively controlling and managing the negative pressure situation in the pipeline.

[0003] Regarding the above related technologies, the inventor believes that when installing conventional negative pressure suppressors, it is often necessary to install negative pressure suppressors with different pressures according to different negative pressure levels. When the pressure change in the pipeline is too large, it is easy to cause the situation that the negative pressure suppressor is difficult to adapt, thus affecting the scope of use of the negative pressure suppressor.

[0004] The above information disclosed in this background technique is only used to increase the understanding of the background technique of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

[0006] A new type of horizontal pipeline negative pressure suppressor provided by this application adopts the following technical solutions:

[0007] A new type of horizontal pipeline negative pressure suppressor includes a connecting pipe and a spring. The top of the connecting pipe is communicated with a decompression pipe. A shielding disk is slidably connected to the inner wall of the decompression pipe. The center of the shielding disk is on the same straight line as the center of the decompression pipe. The bottom end of the spring is fixedly installed with a connecting disk. The inner wall of the connecting disk is threadedly connected with a threaded rod. The bottom end of the threaded rod is fixedly installed with a bearing. The bottom end of the bearing is rotatably connected to a bottom frame. The surface of the bottom frame is fixedly installed with the inner wall of the decompression pipe. The center of the bottom frame is on the same straight line as the center of the threaded rod. A plurality of connecting holes are opened on the surface of the shielding disk, and the plurality of connecting holes are arranged in a circumferential array with the center of the shielding disk as the axis.

[0008] Preferably, two sliding rails are slidably connected to the inner wall of the connecting plate. The bottom ends of the sliding rails are fixedly installed on the top of the chassis, and the two sliding rails are symmetrically distributed with the connecting plate as the axis.

[0009] Preferably, a shielding ring is fixedly connected to the surface of the shielding plate. The shielding ring is a rubber ring, and the size specifications of the surface of the shielding ring are in interference fit with the inner wall size specifications of the decompression pipe.

[0010] Preferably, an observation plate is fixedly installed on the surface of the decompression pipe. The observation plate is a transparent glass plate, and a number of scale marks are provided on the surface of the observation plate. The number of scale marks are evenly distributed on the surface of the observation plate.

Detailed implementation manners

[0020] The following further elaborates on this application in conjunction with Figure 1 —4.

The top of the connecting pipe 1 is communicated with a decompression pipe 2. A shielding disk 3 is slidably installed on the inner wall of the decompression pipe 2. The top of the decompression pipe 2 is shielded by means of the shielding disk 3. A number of connection holes 8 are opened on the inner wall of the shielding disk 3. Through the connection holes 8, the pressure in the decompression pipe 2 is discharged conveniently to ensure the pressure balance in the connecting pipe 1. A spring 4 is installed at the bottom end of the shielding disk 3. A connecting disk 5 is installed at the bottom end of the spring 4.

The surface of the chassis 7 is fixedly connected to the inner wall of the decompression pipe 2. Rotating the threaded rod 6 drives the connecting disk 5 to move up and down, thereby adjusting the pulling force of the spring 4 on the shielding disk 3, facilitating the adaptation to pipelines with different pressures, and effectively expanding the application range of the negative pressure suppressor.

A shielding ring 11 made of rubber is fixedly installed on the surface of the shielding disk 3. The surface of the shielding ring 11 is slidably connected to the inner wall of the decompression pipe 2. The waterproof property of the rubber material of the shielding ring 11 is used to prevent gaps between the shielding disk 3 and the decompression pipe 2, preventing rainwater and impurities in the external environment from entering the decompression pipe 2.

[0023] Referring to Figure 3 - Figure 4, an observation plate 13 made of transparent glass is installed on the surface of the decompression pipe 2.

One end of the connection plate 5 is installed with a slider 12, and one end of the slider 12 is slidably connected to one end of the observation plate 13. By means of the slider 12, it is aligned with the height of the connection plate 5 and slidably connected to one end of the observation plate 13, avoiding the influence of the water flow in the decompression pipe 2 on the observation of the connection plate 5.

The inner wall of the connection plate 5 is threadedly connected with a threaded rod 6. The bottom end of the threaded rod 6 is installed with a chassis 7 by means of a bearing 10, and the surface of the chassis 7 is fixedly connected to the inner wall of the decompression pipe 2, so as to rotate the threaded rod 6 to drive the connection plate 5 to move up and down, thereby adjusting the pulling force of the spring 4 on the shielding plate 3 and facilitating the adaptation to pipelines with different pressures. Two slide rails 9 are slidably connected to the inner wall of the connection plate 5, and the bottom ends of the slide rails 9 are fixedly installed on the top of the chassis 7, so as to limit the angle of the connection plate 5 by means of the slide rails 9 and avoid the rotation of the connection plate 5 during movement. A shielding ring 11 made of rubber is fixedly installed on the surface of the shielding plate 3, and the surface of the shielding ring 11 is slidably connected to the inner wall of the decompression pipe 2, so as to prevent the existence of gaps between the shielding plate 3 and the decompression pipe 2 by means of the waterproof property of the rubber material of the shielding ring 11, and prevent rainwater and impurities in the external environment from entering the decompression pipe 2.

[0025] An observation plate 13 made of transparent glass can also be installed on the surface of the decompression pipe 2. A number of scale marks 14 are provided on the surface of the observation plate 13, so as to facilitate the staff to observe the height of the connection plate 5 by means of the transparent glass material of the observation plate 13, and facilitate the observation of the pressure data of the shielding plate 3 by means of the scale marks 14, which is more convenient in use. One end of the connection plate 5 is installed with a slider 12, and one end of the slider 12 is slidably connected to one end of the observation plate 13, so as to be aligned with the height of the connection plate 5 by means of the slider 12 and slidably connected to one end of the observation plate 13, avoiding the influence of the water flow in the decompression pipe 2 on the observation of the connection plate 5.
