Description

Technical Field

[0001] This utility model belongs to the field of pipeline waterproofing technology, specifically a water-blocking device for flushing pipe fittings. Background Technology

[0002] Water-blocking devices for pipe flushing are essential for the maintenance and cleaning of piping systems. In industrial, building, and municipal engineering projects, piping systems are critical components for transporting liquids such as water, oil, and chemicals. These pipes can accumulate dirt, rust, or other deposits over time, affecting their efficiency and safety. Therefore, regular flushing and cleaning are particularly important.

[0003] In industrial production, the flushing pressure of flushing systems may fluctuate during operation. If the water-blocking device cannot adapt well to these pressure changes, it may experience seal failure when the pressure rises, or fail to fit the pipes tightly when the pressure drops, leading to problems such as leakage or incomplete flushing.

[0004] However, existing water-blocking devices for pipe flushing may not seal properly during the flushing process, leading to water leakage. This leakage affects the flushing effect and the working environment.

[0005] Therefore, this utility model provides a water-blocking device for flushing pipe fittings. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown, this utility model discloses a water-blocking device for flushing pipe fittings, comprising a first support frame 11 fixedly fitted onto one end of a pipe 1, an L-shaped second support frame 12 fixedly installed on the top of the first support frame 11, and a first electric actuator 13 fixedly installed at the bottom of the other end of the second support frame 12; a connecting block 16 fixedly installed at the lower end of the first electric actuator 13, a second electric actuator 14 fixedly installed on the side of the connecting block 16 near the end of the pipe 1, a first fixing block 15 fixedly connected to the end of the second electric actuator 14, and a plug 2 fixedly installed on the side of the first fixing block 15 near the end of the pipe 1; in use, the first support frame 11 is first fixed to the side of the pipe 1 near the end, and then the second support frame 12 is fixed. At the top of the first support frame 11, the first electric actuator 13 is activated, causing it to begin working. Under the internal thrust of the first electric actuator 13, the connecting block 16 moves slowly until it and the pipe 1 are at the same horizontal level. At this time, the second electric actuator 14 is activated, and the first fixing block 15 and the plug 2 will slowly approach the port of the pipe 1 until they are tightly fitted. Through the coordinated operation of the first electric actuator 13 and the second electric actuator 14, the position of the plug 2 can be adjusted at any time, facilitating the loading and unloading of materials during production. At the same time, the setting of the first fixing block 15 allows the plug 2 to more stably block the port of the pipe 1, reducing the occurrence of leakage.

[0025] like Figure 2As shown, a sliding cylinder 22 is concentrically fixed on the side of the plug 2 near the end of the pipe 1. A sliding rod 23 is axially slidably fitted inside the sliding cylinder 22. A second fixing block 24 is fixedly installed at the other end of the sliding rod 23. A spring 25 is sleeved on the outside of the sliding rod 23. The two ends of the spring 25 are fixedly connected to the plug 2 and the second fixing block 24, respectively. An annular elastic cloth 21 is fixedly fitted on the outside of the second fixing block 24. The outer edge of the annular elastic cloth 21 is fixedly connected to the plug 2. In use, as the position of the first fixing block 15 is adjusted and moved, the plug 2 slowly approaches the end of the pipe 1. Finally, under the action of the first fixing block 15, the plug... The side wall of the plug 2 and the end of the pipe 1 are tightly fitted and sealed. The water flow inside the pipe 1 will squeeze the surface of the elastic cloth 21. The elastic cloth 21 will drive the second fixing block 24 to retract towards the plug 2. At this time, the second fixing block 24 will compress the slide rod 23 and the spring 25, causing the slide rod 23 and the spring 25 to retract along the slide cylinder 22 towards the plug 2. By setting the slide cylinder 22 and the slide rod 23, with the cooperation of the spring 25, the movement of the elastic cloth 21 along the slide cylinder 22 towards the plug 2 can be better controlled. At the same time, the pressure of the water flow on the elastic cloth 21 is evenly distributed, reducing the chance of leakage of the plug 2.

[0026] like Figure 3 As shown, multiple rubber rings 3 are fixedly fitted on the outer surface of the elastic cloth 21, and the multiple rubber rings 3 are arranged on the elastic cloth 21 in a uniformly outward expansion manner. When in use, when the plug 2 blocks the port of the pipe 1, the water flow inside the pipe 1 will first squeeze the elastic cloth 21, causing the elastic cloth 21 to undergo elastic change. At this time, the rubber rings 3 set on the surface of the elastic cloth 21 will also undergo elastic change along with the elastic cloth 21. By setting multiple rubber rings 3, the overall tightness of the plug 2 is increased, the possibility of leakage is reduced, and the pressure on the elastic cloth 21 is also shared, reducing its damage under the action of water flow pressure.

[0027] Working principle: In use, first fix the first support frame 11 to the side of the pipe 1 near the end, then fix the second support frame 12 to the top of the first support frame 11. At this time, start the first electric actuator 13 to push the connecting block 16 to move until the connecting block 16 and the pipe 1 are at the same horizontal height, then pause. Start the second electric actuator 14 to slowly move the plug 2 towards the end of the pipe 1. Finally, under the action of the first fixing block 15, the side wall of the plug 2 and the end of the pipe 1 are tightly fitted and contacted, sealing the pipe. At the port of pipe 1, the water flow inside pipe 1 will squeeze the surface of elastic cloth 21. The elastic cloth 21 will drive the second fixing block 24 to retract towards the plug 2. At this time, the second fixing block 24 will compress the sliding rod 23 and the spring 25, causing the sliding rod 23 and the spring 25 to retract along the sliding cylinder 22 towards the plug 2. When the plug 2 blocks the port of pipe 1, the water flow inside pipe 1 will first squeeze the elastic cloth 21, causing the elastic cloth 21 to undergo elastic change. At this time, the rubber ring 3 set on the surface of the elastic cloth 21 will also undergo elastic change along with the elastic cloth 21.

[0028] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 4-5 As shown, a connecting rod 17 is fixedly installed at the bottom of the first fixing block 15, and a collection box 4 is fixedly installed at the lower end of the connecting rod 17, with the collection box 4 located directly below the plug 2. The collection box 4 is equipped with multiple first sponges 5 and second sponges 51, which are arranged in a crisscross pattern. When the plug 2 is pulled out of the pipe 1, the collection box 4 can collect the water droplets remaining inside the pipe 1. When the collection box 4 collects the water flow remaining inside the pipe 1, the water flow will first come into contact with the first sponges 5 and second sponges 51, and then slowly drip down along the first sponges 5 and second sponges 51 to the bottom of the collection box 4. By setting the first sponges 5 and second sponges 51, the situation of water splashing out to the surroundings is alleviated, and the water flow is also easy to collect and pour.

[0029] The bottom of the collection box 4 has a slot 61, into which a hemispherical elastic bag 6 is inserted. In use, the elastic bag 6 is first attached to the slot 61, and then the elastic bag 6 is firmly fixed to the bottom of the collection box 4 through the slot 61 to collect the liquid dripping from the top of the collection box 4. By setting the elastic bag 6, the liquid collected inside the collection box 4 can be poured out more effectively, avoiding excessive liquid and excessive gravity, which would disrupt the overall working coordination.
