Description

Technical Field

[0001] This utility model relates to the field of vortex flow sensor technology, specifically a vortex flow sensor housing. Background Technology

[0002] Vortex flow meters are velocity-type flow meters made based on the von Kármán vortex street theory and utilizing the natural vibration principle of fluids, using piezoelectric crystals or differential capacitors as detection components.

[0003] As disclosed in Chinese Patent CN 217504896 U, this utility model discloses a vortex flow sensor housing, including a cylindrical housing, a numerical display structure disposed on the top of the cylindrical housing, a highly corrosion-resistant layer disposed inside the cylindrical housing, an adhesive layer disposed inside the highly corrosion-resistant layer, an adhesive layer disposed inside the adhesive layer, an intermediate layer disposed inside the adhesive layer, an inner bottom layer disposed inside the intermediate layer, and an alloy element powder layer disposed inside the highly corrosion-resistant layer, which works in conjunction with the highly corrosion-resistant layer. This utility model achieves a highly corrosion-resistant effect. This vortex flow sensor housing solves the problem that existing vortex flow sensor housings are generally made of stainless steel, which has limited corrosion resistance. After prolonged exposure to fluid erosion, the surface quality of the stainless steel is affected, thus affecting the overall performance of the vortex flow sensor.

[0004] The aforementioned patent background technology states that existing devices have limited corrosion resistance, thus affecting the overall performance of vortex flow sensors. However, after a certain number of years of use or due to external interference, such as collisions with objects, vortex flow sensors may be damaged. In such cases, maintenance is required. The aforementioned patent requires the entire vortex flow sensor to be disassembled for maintenance, making it inconvenient to open the internal components of the vortex flow sensor, which may reduce the maintenance efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a housing for a vortex flow sensor, which has the advantages of facilitating personnel maintenance and repair of the vortex flow sensor and improving the maintenance efficiency of the vortex flow sensor, thus solving the problem that the maintenance efficiency of the vortex flow sensor is reduced due to the cumbersome maintenance process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vortex flow sensor housing, comprising a sensor body, a connecting pipe connected to the bottom of the sensor body, connecting flanges fixedly connected to both the left and right sides of the connecting pipe, and openings on both the front and rear sides of the sensor body, with a cover body one and a cover body two respectively disposed inside the openings. Connecting limiting shells are fixedly connected to both the left and right sides of the sensor body, with limiting plates one and two respectively inserted inside the connecting limiting shells. Slots are provided inside both limiting plates one and the connecting limiting shells, and telescopic limiting rods are movably connected inside the slots. A sliding plate is fixedly connected to the bottom of the telescopic limiting rod, and a spring is fixedly connected to the bottom of the sliding plate. The spring is fixedly connected to limiting plate one, and limiting plates one and two are fixedly connected to cover body one and cover body two respectively.

[0007] As a preferred embodiment of this utility model, a magnetic strip is fixedly connected to the top inner side of the connecting limiting shell, and a concave magnetic frame is sleeved on the surface of the magnetic strip.

[0008] As a preferred embodiment of this utility model, a threaded rod is fixedly connected to the bottom of the concave magnetic frame, and the concave magnetic frame is movably connected to the first limiting plate and the second limiting plate respectively through the threaded rod.

[0009] As a preferred embodiment of this utility model, a sealing strip is fixedly connected to the surfaces of the first cover and the second cover. The sealing strip is circular and fits into the interior of the sensor body.

[0010] As a preferred embodiment of this utility model, the second limiting plate has an opening inside, and a connecting door is movably connected inside the opening by screws.

[0011] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the top of the connecting limiting shell, and a positioning rod is threadedly connected to the inside of the connecting plate, with the tail end of the positioning rod penetrating into the interior of the telescopic limiting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a connecting limiting shell, allows for easy maintenance of the sensor body when the telescopic limiting rod is pressed down. Simultaneously, the sliding plate is pushed to slide inside the limiting plate one, compressing the springs and shortening their spacing. This causes the telescopic limiting rod to temporarily retract inside the limiting plate one. Then, the cover one and cover two are pulled forward and backward to remove the limiting plate one and the limiting shell. This facilitates the maintenance of the internal parts of the sensor body without disassembling the sensor body, thus improving the maintenance efficiency of the sensor body.

[0014] 2. By setting up a magnetic strip, this utility model utilizes the principle of opposite poles attracting each other, which allows the magnetic strip to be firmly attached to the inside of the concave magnetic frame, thereby improving the locking effect of the first limiting plate and the second limiting plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6As shown, the present invention provides a vortex flow sensor housing, including a sensor body 1. The bottom of the sensor body 1 is connected to a connecting pipe 2. Connecting flanges 3 are fixedly connected to both the left and right sides of the connecting pipe 2. The front and rear sides of the sensor body 1 are provided with openings 4. Cover body 5 and cover body 20 are respectively provided inside the openings 4. Connecting limiting shells 6 are fixedly connected to both the left and right sides of the sensor body 1. Limiting plate 7 and limiting plate 8 are respectively inserted inside the connecting limiting shells 6. The limiting plate 7 and the connecting limiting shell 6 are both provided with slots 21. Telescopic limiting rods 9 are movably connected inside the slots 21. A sliding plate 10 is fixedly connected to the bottom of the telescopic limiting rod 9. A spring 11 is fixedly connected to the bottom of the sliding plate 10. The spring 11 is fixedly connected to the limiting plate 7. The limiting plate 7 and the limiting plate 8 are fixedly connected to the cover body 5 and the cover body 20, respectively.

[0024] refer to Figure 4 A magnetic strip 12 is fixedly connected to the top inner side of the connecting limiting shell 6, and a concave magnetic frame 13 is sleeved on the surface of the magnetic strip 12.

[0025] As a technical optimization of this utility model, by setting up a magnetic strip 12, the magnetic strip 12 can be firmly attached to the inside of the concave magnetic frame 13 by utilizing the principle of opposite poles attracting each other, which can improve the snapping effect on the limiting plate 7 and the limiting plate 8.

[0026] refer to Figure 4 The bottom of the concave magnetic frame 13 is fixedly connected to a threaded rod 14, and the concave magnetic frame 13 is movably connected to the limiting plate 7 and the limiting plate 8 respectively through the threaded rod 14.

[0027] As a technical optimization of this utility model, by setting the threaded rod 14, the concave magnetic frame 13 can be removed later through the threaded rod 14, so that the concave magnetic frame 13 has the advantage of being separable from the limiting plate 7 and the limiting plate 8, which makes it convenient for personnel to disassemble and assemble it later.

[0028] refer to Figure 6 A sealing strip 15 is fixedly connected to the surface of the first cover 5 and the second cover 20. The sealing strip 15 is circular and fits into the interior of the sensor body 1.

[0029] As a technical optimization of this utility model, by setting a sealing strip 15, the gap between the cover body 5 and the cover body 20 and the sensor body 1 can be filled, thereby improving the sealing effect of the cover body 5 and the cover body 20 on the sensor body 1.

[0030] refer to Figure 5The limiting plate 8 has an inspection port 16 inside, and the inspection port 16 is movably connected to a connecting door 17 by screws.

[0031] As a technical optimization of this utility model, by setting up an inspection port 16, and through the cooperation of the inspection port 16 and the connecting door 17, it is convenient for personnel to open the interior of the limit plate 7, which facilitates the inspection and maintenance of the internal device of the limit plate 7 in the future.

[0033] As a technical optimization of this utility model, by setting a positioning rod 19, after the telescopic limiting rod 9 is inserted into the slot 21, the positioning rod 19 can be rotated one turn through the thread so that the tail end of the positioning rod 19 is inserted into the telescopic limiting rod 9, thereby limiting the telescopic limiting rod 9 and improving the limiting effect of the telescopic limiting rod 9.

[0034] The working principle and usage process of this utility model: In daily use, after connecting the connecting pipe 2 to other pipes through the connecting flange 3, it can be used. When the sensor body 1 needs to be inspected and maintained, press the telescopic limit rod 9 downward, and at the same time push the slide plate 10 to slide inside the limit plate 7, while squeezing the spring 11 to shorten the gap of the spring 11 itself. At the same time, the telescopic limit rod 9 is temporarily retracted into the limit plate 7. Then, pull the cover 5 and the cover 20 forward and backward to pull out the limit plate 7 and the limit plate 28 and connect the limit shell 6. This makes it convenient for personnel to inspect and maintain the parts inside the sensor body 1 without disassembling the sensor body 1, thereby improving the maintenance efficiency of the sensor body 1.
