Description

Technical Field

[0001] The utility model relates to the technical field of heating pipe leakage prevention equipment, in particular to a heating pipe leakage prevention device. Background Art

[0002] The heating network, also known as the thermal network, is the heating pipeline that starts from the boiler room, direct-fired machine room, heating center, etc., and leads from the heat source to the thermal entrance of the building.

[0003] The structure of the existing heating network is mainly composed of heat source, heat transmission pipeline and heat dissipation equipment. The heat source is usually the boiler room of the heating company or large factory, which is responsible for generating heat energy and transferring it to the heat transmission pipeline. The heat transmission pipeline is the pipeline connecting the heat source and the heat dissipation equipment, which is responsible for transporting heat energy from the heat source to the heat dissipation equipment of each user. The heat dissipation equipment is the equipment that converts heat energy into indoor temperature, such as radiators and floor heating.

[0004] During the heating process, leakage of the heating pipe will cause insufficient heating. The existing equipment on the heating pipe cannot detect whether the pipe is leaking. When the pipe leaks, it is not easy to find it in time, resulting in waste of resources and affecting the heating effect. Therefore, a heating pipe leakage prevention device is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised by the above-mentioned background technology, the utility model proposes a heating pipe leakage prevention device.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: a heating pipe leakage prevention device described in the utility model comprises a mounting assembly and a detection mechanism; the detection mechanism comprises a box body, a rod hole is provided on the top of the box body, a lifting rod is inserted in the rod hole, and a rotating cap is fixedly connected to the top of the lifting rod, a vent hole is provided at the bottom end of the lifting rod, a threaded portion is provided on the lifting rod, and the threaded portion is rotatably installed in a threaded sleeve, a mounting hole is provided at the bottom of the box body, a threaded sleeve is fixed in the mounting hole, a flow guide port is provided on the threaded portion, a pipe hole is opened on one side of the top of the box body, a sleeve is fixedly connected to the port of the pipe hole, a movable block is provided in the sleeve, a circular hole is provided on the sleeve, a movable rod is inserted in the circular hole, the bottom end of the movable rod is fixedly connected to the movable block, and an anti-drop cap is fixedly connected to the top end of the movable rod, a spring is fixedly connected between the anti-drop cap and the sleeve, and the spring is sleeved on the movable rod, and a movable electrode plate is fixedly connected to the anti-drop cap.

When installing the anti-leakage detection mechanism, it is necessary to perform a self-inspection on the anti-leakage detection mechanism. When performing the self-inspection, first open the first one-way valve, and pull the pull plate to move the piston block outward, so that the gas can be drawn into the gas box, then push the pull plate inward, and open the second one-way valve, so that the piston block pushes the gas in the gas box into the box body, as the air pressure in the box body increases, the movable block will push the movable rod to move upward, and then the anti-drop cap drives the movable electrode plate to move up to contact with the fixed electrode plate, so that the indicator light is energized to sound an alarm, which can indicate that the anti-leakage detection mechanism itself has good air tightness, so as to better ensure the accuracy of subsequent detection of the heating pipe;

[0007] After the anti-leakage detection mechanism is installed, rotate the lifting rod so that the threaded part drives the air hole at the bottom of the lifting rod to move vertically downward into the heating pipe. When the heating pipe is airtight, the gas in the heating pipe will flow into the air hole and then be discharged through the guide port. The air pressure in the box will increase, causing the movable block to push the movable rod to move upward, and then the anti-drop cap drives the movable electrode plate to move up and contact with the fixed electrode plate, so that the indicator light is energized and an alarm is sounded, thereby indicating that the heating pipe is airtight. When the heating pipe leaks, the indicator light will not sound an alarm, so that whether the pipeline is leaking can be detected. When the pipeline leaks, it can be discovered in time to avoid waste of resources while ensuring the heating effect.

[0008] Preferably, a rubber strip is fixed to the bottom end of the box body, and by providing the rubber strip, the anti-leakage detection mechanism can be in close contact with the outer surface of the heating pipe.

[0010] Preferably, ropes are fixedly connected on both sides of the box body, threaded connecting tubes are fixedly connected to the bottom ends of the two ropes, and the threaded connecting tubes are rotatably installed on the threaded rods. The installation assembly includes an arc-shaped mounting seat, two fixed blocks are fixedly connected to the two arc-shaped mounting seats, screw holes are opened on the two fixed blocks, threaded rods are rotatably installed in the two screw holes, and nuts are fixedly connected to one end of the two threaded rods. When installing the anti-leakage detection device, the arc-shaped mounting seat is first contacted with the bottom end of the heating pipe, and then the two threaded connecting tubes are respectively sleeved on the threaded rods, and the threaded rods are rotated. With the cooperation of the ropes, the anti-leakage detection device can be quickly installed on the heating pipe, which is convenient for subsequent detection of whether the heating pipe is leaking.

[0011] The utility model is beneficial in that:

[0012] 1. When installing the leak detection mechanism of the utility model, the leak detection mechanism needs to be self-checked. When performing the self-check, first open the first one-way valve, and pull the pull plate to move the piston block outward, so that the gas can be drawn into the gas box, then push the pull plate inward, and open the second one-way valve, so that the piston block pushes the gas in the gas box into the box body. As the air pressure in the box body increases, the movable block will push the movable rod to move upward, and then the anti-drop cap will drive the movable electrode plate to move up to contact with the fixed electrode plate, so that the indicator light is powered on and an alarm is sounded, which can indicate that the leak detection mechanism itself has good air tightness, so as to better ensure the accuracy of subsequent detection of the heating pipe;

[0013] 2. After the anti-leakage detection mechanism of the utility model is installed, the lifting rod is rotated so that the threaded portion drives the air hole at the bottom of the lifting rod to move vertically downward into the heating pipe. When the air tightness of the heating pipe is good, the gas in the heating pipe will flow into the air hole and then be discharged through the guide port. The air pressure in the box will increase, so that the movable block will push the movable rod to move upward, and then the anti-drop cap will drive the movable electrode plate to move up and contact with the fixed electrode plate, so that the indicator light is powered on and an alarm is sounded, thereby indicating that the air tightness of the heating pipe is good. When the heating pipe leaks, the indicator light will not sound an alarm, thereby making it possible to detect whether the pipeline is leaking.
