Description

Technical Field

[0001] This utility model relates to the field of ultrasonic water meter technology, and in particular to a pressure-resistant and waterproof ultrasonic water meter. Background Technology

[0002] An ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed of an ultrasonic beam as it propagates upstream and downstream in water, analyzes and processes the data to obtain the water flow rate, and then further calculates the water flow.

[0003] During the use of ultrasonic water meters, water pipe valves may be closed or opened, resulting in a water hammer effect inside the pipe. This causes the ultrasonic water meter's detection part to be subjected to a large water pressure impact. However, existing ultrasonic water meters lack pressure-resistant mechanisms, which can easily lead to the detection part being damaged by the water flow. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing ultrasonic water meters, which lack a pressure-resistant mechanism and are prone to damage to the detection part due to water hammer effect. Therefore, this invention proposes a pressure-resistant and waterproof ultrasonic water meter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pressure-resistant and waterproof ultrasonic water meter includes an installation tube and an ultrasonic water meter body. The ultrasonic water meter body is fixed to the installation tube. A protective shell is fixedly connected to the top outer wall of the installation tube and covers the outside of the ultrasonic water meter body. A first sealing ring is snapped into the top of the protective shell, and a protective cover is rotatably connected to the top of the protective shell. A pressure-resistant tube is fixedly connected to the top of the installation tube. A spring is installed inside the pressure-resistant tube. The top end of the spring is fixedly connected to the top inner wall of the pressure-resistant tube, and a sealing plate is fixedly connected to the bottom end of the spring. A partition is fixedly connected between the two inner walls of the installation tube, and the top of the partition is located inside the pressure-resistant tube.

[0007] Furthermore, a latch is fixedly connected to one side of the outer wall of the protective shell, and the latch is engaged with the protective cover.

[0008] Furthermore, flanges are fixedly connected to both ends of the mounting pipe.

[0009] Furthermore, an observation window is fitted into the top of the protective cover.

[0010] Furthermore, a sealing block is adhered to the inner side of the protective cover, and the sealing block is in contact with the first sealing ring.

[0011] Furthermore, a second sealing ring is bonded to the bottom of the sealing plate.

[0012] Furthermore, a filter screen is snapped into the side of the partition inside the installation tube.

[0013] Furthermore, a drain pipe is inserted into the bottom of the mounting pipe.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The water flow is divided into two streams by a baffle. One stream flows into the pressure-resistant pipe along the top of the baffle, while the other stream flows outward along the bottom of the baffle, thereby dividing the pressure and avoiding water hammer effect, so as not to damage the ultrasonic water meter body.

[0016] 2. The ultrasonic water meter body is protected by placing the protective cover on top of the protective shell and locking the cover with a buckle.

[0017] 3. The protective cover and the protective shell are sealed by the first sealing ring and the sealing block to prevent rainwater from entering the protective shell and causing damage to the ultrasonic water meter body. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-3A pressure-resistant and waterproof ultrasonic water meter includes an installation pipe 1 and an ultrasonic water meter body 2. The ultrasonic water meter body 2 is fixed to the installation pipe 1. A protective shell 3 is bolted to the top outer wall of the installation pipe 1 and covers the outside of the ultrasonic water meter body 2. A first sealing ring 4 is snapped onto the top of the protective shell 3. A protective cover 5 is rotatably connected to the top of the protective shell 3. Covering the top of the protective shell 3 with the protective cover 5 protects the ultrasonic water meter body 2. A pressure-resistant pipe 7 is welded to the top of the installation pipe 1, and the pressure-resistant pipe 7 contains... There is a spring 8, the top of which is fixedly connected to the inner wall of the top of the pressure-resistant pipe 7. A sealing plate 9 is welded to the bottom of the spring 8. The water flow impacts the sealing plate 9, and the impact of the water flow is slowed down by the spring 8, thereby reducing the impact of the water flow on the pressure-resistant pipe 7. A partition 10 is welded between the inner walls of the two sides of the installation pipe 1. The top of the partition 10 is located inside the pressure-resistant pipe 7. The water flow is split into two streams by the partition 10, thereby dividing the pressure and avoiding the water hammer effect, so as not to damage the ultrasonic water meter body 2.

[0024] One side of the outer wall of the protective shell 3 is fixed with a latch 6 by bolts. The latch 6 is fastened to the protective cover 5, thereby locking the protective cover 5. Flanges 11 are welded to both ends of the installation tube 1. An observation window 12 is embedded in the top of the protective cover 5, so as to facilitate the observation of the data on the ultrasonic water meter body 2. A sealing block 13 is bonded to the inside of the protective cover 5. The sealing block 13 contacts the first sealing ring 4. The first sealing ring 4 and the sealing block 13 seal the protective cover 5 and the protective shell 3, thereby preventing rainwater from entering the protective shell 3. A second sealing ring 14 is bonded to the bottom of the sealing plate 9. A filter screen 15 is snapped into the side of the partition 10 inside the installation tube 1. A drain pipe 16 is inserted into the bottom of the installation tube 1. A manual valve is provided on the drain pipe 16. When the manual valve is opened, the impurities filtered by the filter screen 15 are discharged from the drain pipe 16.

[0025] Working principle: When in use, after the valve is opened, water flows into the installation pipe 1, and then the filter screen 15 filters the impurities in the water flow. When the water flow reaches the position of the baffle 10, the water flow is divided into two streams by the baffle 10, thereby dividing the pressure and avoiding the water hammer effect. One stream of water flows into the pressure-resistant pipe 7 along the top of the baffle 10. When the water flows into the pressure-resistant pipe 7, the water flow impacts the sealing plate 9, and the impact of the water flow is slowed down by the spring 8. The other stream of water flows outward along the bottom of the baffle 10. Under the water pressure of this stream, the water in the pressure-resistant pipe 7 is stored in the pressure-resistant pipe 7. After the valve is closed, the water in the pressure-resistant pipe 7 flows downward and is discharged from the installation pipe 1.

[0026] Then, the protective cover 5 is placed on top of the protective shell 3 and locked with the buckle 6 to protect the ultrasonic water meter body 2. Next, the protective cover 5 and the protective shell 3 are sealed by the first sealing ring 4 and the sealing block 13 to prevent rainwater from entering the protective shell 3. Then, the manual valve is opened to discharge the impurities filtered by the filter screen 15 from the drain pipe 16.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
