Description

Technical Field

[0001] The utility model relates to the technical field of fire detection, in particular to a water testing joint for fire detection. Background Art

[0002] The water test joint for fire detection is a device specially used to test the fire safety performance of buildings and facilities. It usually consists of one or more rotatable ball valves and a measurable pipe. In fire detection, the water test joint is used to simulate real fire conditions and measure and record key parameters such as water flow and water pressure to ensure the effectiveness and feasibility of the fire protection system and evacuation plan.

[0003] However, in the current existing technology, when conducting a water test on a fire water pipe, the water test joint is connected to the water pipe. Since the internal pressure of the fire water pipe suddenly leaks out when the water is turned on, the water pressure will increase, which will cause the connection to loosen due to impact. As a result, some water splashes out from the connection between the water pipe and the water test joint, causing water splashing and waste. In addition, water leakage will cause the internal pressure to leak out, which will affect the test results. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention.

[0020] Example

The air bin 4 is also provided with a hole slot 5 and a locking block 6. A positioning rod 501 and a spring 502 are provided inside the hole slot 5. The positioning rod 501 is used to position the angle of the locking block 6 and the slider 601 when they move. The spring 502 is used to support the locking block 6 so that it is located in the air bin 4. The outer wall of the locking block 6 is provided with a slider 60 1, the inner wall of the cavity 2 is provided with a mounting frame 7, and the inner wall of the mounting frame 7 is provided with a plurality of baffles 8, which can block the water flow when it is sprayed out to reduce the impact of the water flow, and cooperate with the through groove 801 in the baffle 8 to cut the water flow, thereby further reducing the impact of the water flow, and the plurality of baffles 8 are provided with through grooves 801 inside, and the outer wall of the plug connector of the connecting pipe 9 is provided with an embedded groove 901, when the water flow contacts the baffle 8, the baffle 8 can be pushed to rotate in the mounting frame 7 and shrink to the cavity 2, and at the same time, the support plate 3 is pressed to be embedded when shrinking. The air in the air bin 4 is squeezed to increase the air pressure. As the air pressure increases, the locking block 6 at the other end of the air bin 4 can be pushed out and extended into the embedded groove 901 on the outer wall of the connecting pipe 9 plug connector, so as to clamp and fix the connecting pipe 9. After the connecting pipe 9 and the connector 1 are installed, the embedded groove 901 on the outer wall corresponds to the opening at the end of the air bin 4 inside the connector 1 away from the cavity 2. The locking block 6 is an arc-shaped structure away from the end of the air bin 4, and multiple locking blocks 6 can be combined into a circular structure, so that after extending, the gap between the water pipe and the water test connector can be filled to increase the sealing effect.

[0022] In this embodiment, all electrical components are controlled by conventional controllers.

[0023] For example, please refer to Figure 1-4 , one end of the plurality of support plates 3 is located in the cavity 2, and the other end extends into the gas chamber 4 and is connected to the piston 301 by bolts, the piston 301 is slidably connected to the inside of the gas chamber 4, the inner wall of the gas chamber 4 is loaded with high-pressure gas, the locking block 6 is located at the end of the gas chamber 4 away from the cavity 2, and is slidably connected to the inner wall of the gas chamber 4 through a slide rail, the locking block 6 is a conical structure at the end away from the gas chamber 4, and can extend from the gas chamber 4 to the joint 1, the slider 601 is connected to the outer wall of the locking block 6 by welding, the other end of the slider 601 extends into the hole groove 5, and is slidably connected to the inner wall of the hole groove 5, the positioning rod 501 passes through the slider 601 Both ends of the spring 502 are connected to the inner wall of the hole groove 5 and the slider 601 by welding, the mounting frame 7 is connected to the inner wall of the cavity 2 by bolts, the inner wall of the mounting frame 7 is a hollow structure, and the multiple baffles 8 are all conical structures and are rotatably connected to the inner wall of the mounting frame 7 through the spring shaft. The mounting frame 7 is located at the front end of the installation position of the connecting pipe 9 in the joint 1, and the plug connector at one end of the connecting pipe 9 is embedded and connected to the inner wall of the joint 1 and fixed by bolts. When the valve of the connecting pipe 9 is opened, the water flow can impact the baffle 8 to rotate and shrink it, and squeeze the support plate 3, so that the locking block 6 extends into and embeds into the embedded groove 901 of the outer wall of the plug connector. When in use, first insert the plug connector of the fire water pipe into the connector 1 and fix it with bolts. When the water pipe valve is opened and water flows out, it will abut against the baffle 8, and the baffle 8 will block and divide the water flow, thereby buffering the impact force of the water flow. At the same time, the baffle 8 will be impacted to rotate and shrink into the cavity 2, and the support plate 3 in the cavity 2 will be pressed to drive the support plate 3 to shrink into the air chamber 4.

[0024] The working process of the utility model is as follows: when in use, the plug connector of the fire hose is first inserted into the connector 1 and fixed by bolts. When the water pipe valve is opened and the water flow is sprayed out, it will abut against the baffle 8, be blocked and cut by the baffle 8, buffer the impact force of the water flow, and at the same time, the baffle 8 is impacted to rotate and shrink to the cavity 2, and the support plate 3 in the cavity 2 is pressed to drive the support plate 3 to shrink into the air chamber 4, and at the same time, the gas in the air chamber 4 is squeezed by the piston 301, and the air pressure in the air chamber 4 is increased. As the air pressure increases, the locking block 6 at the other end of the air chamber 4 can be pushed out and extended into the embedded groove 901 of the outer wall of the plug connector of the connecting pipe 9, so as to clamp and fix the connecting pipe 9, and fill the gap where the water pipe and the water test connector are connected.
