[0002] The orifice flowmeter is a differential pressure flowmeter widely used in various industries and fields. It is mainly used to measure the flow of liquid, gas or steam in pipelines. When the fluid flows through the equipment, there is a specific relationship between the pressure difference and the flow rate. The flow rate is measured by measuring this pressure difference. The existing orifice flowmeters can basically meet daily use needs, but there are still some shortcomings that need to be improved.
[0003] The orifice flowmeter widely used on the market can filter and retain most of the impurities or sludge in the fluid through its internal filtering structure, reduce the obstruction of the impurities or sludge to the measurement process, and improve the measurement accuracy of the electromagnetic flowmeter. However, after long-term use, the internal filtering structure is easy to fill up, and when the filtering structure needs to be disassembled, it takes a lot of time and is difficult to install.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] The utility model provides a technical solution: Figures 1 to 5 As shown, in the present embodiment, an anti-clogging orifice flowmeter comprises an orifice flowmeter 1, a control console 2 installed in the middle of the orifice flowmeter 1 and a display panel 3 arranged on the control console 2, a water inlet 4 and a water outlet 5 are respectively arranged on both sides of the orifice flowmeter 1, a sleeve 6 is fixed inside the water inlet 4, a filter cartridge 7 is arranged inside the sleeve 6, positioning plates 8 are fixed to the outer walls on both sides of the filter cartridge 7, positioning slots 9 are opened on both sides of the inner wall of the sleeve 6, two groups of positioning plates 8 can be inserted into the positioning slots 9, and the front ends of the two groups of positioning slots 9 are connected to the limiting plates 12 through movable components.
[0023] By fixing a sleeve 6 inside the water inlet 4 on the orifice flowmeter 1 and installing a detachable filter cartridge 7 in the sleeve 6, the filter cartridge 7 can be quickly fixed in the sleeve 6, so that the filter cartridge 7 can effectively filter the fluid entering from the water inlet 4, and prevent impurities or silt in the fluid from entering the orifice flowmeter 1 and clogging the orifice flowmeter 1. Then, by installing two groups of limit plates 12 that move up and down at the front ends of the two groups of positioning slots 9, the two groups of limit plates 12 can quickly form or release the positioning plug plates 8 in the two groups of positioning slots 9, thereby facilitating the replacement of the filter cartridge 7 and effectively improving the convenience of using the device.
[0024] In other embodiments, the movable assembly includes a guide slot 10, a guide slider 11, a buckle slot 13 and a return spring 14. The two sets of positioning slots 9 are provided with a guide slot 10 at the lower front end, the two sets of guide slots 10 are provided with guide sliders 11, the two sets of limit plates 12 are fixed to the top of the guide slider 11, the two sets of guide sliders 11 are provided with a buckle slot 13 at the front end, and the two sets of guide sliders 11 are provided with a return spring 14 at the bottom end;
[0025] By opening two sets of guide slots 10 at the front end of the sleeve 6 and installing liftable guide slide blocks 11 inside the two sets of guide slots 10, when the filter cartridge 7 needs to be disassembled, the two sets of buckle slots 13 can be buckled downward, so that the two sets of guide slide blocks 11 drive the two sets of limit plates 12 to move downward along the guide slots 10, and the two sets of guide slide blocks 11 squeeze the two sets of return springs 14 during the downward movement. When the two sets of limit plates 12 are completely received in the guide slots 10, the two sets of limit plates 12 can release the two sets of positioning plugs 8, the filter cartridge 7 can be pulled out afterwards, and when the filter cartridge 7 drives the two sets of positioning plug plates 8 to be installed into the two sets of positioning slots 9, the downward force on the two sets of buckle slots 13 can be released, allowing the two sets of return springs 14 to release their elastic force to push the two sets of guide slide blocks 11 to move upward, allowing the two sets of guide slide blocks 11 to drive the two sets of limiting plates 12 to quickly enter the two sets of positioning slots 9, allowing the limiting plates 12 to quickly form an active limiting effect on the two sets of positioning plug plates 8 in the two sets of positioning slots 9, further improving the convenience of the device when used.
[0026] In other embodiments, a sealing rubber ring is glued to the outer wall of the filter cartridge 7;
[0027] Through this design, the gap between the outer wall of the filter cartridge 7 and the inner wall of the sleeve 6 can be reduced, thereby ensuring that the fluid can enter the orifice flowmeter 1 from the filter cartridge 7.

[0030] In other embodiments, the inner walls of the two sets of buckle grooves 13 are both ground;
[0031] Through this design, the friction between the buckle slot 13 and the user's hand can be effectively increased, thereby facilitating the buckle slot 13 to be effectively pushed.
[0032] In other embodiments, the outer wall of the guide slider 11 is fully fitted with the inner wall of the guide slot 10, and the guide slider 11 is slidably connected with the guide slot 10;
[0033] Through this design, when the guide slider 11 drives the limit plate 12 to move up and down along the inner wall of the guide slot 10, it can effectively prevent the guide slider 11 from shaking significantly during the movement, thereby improving the stability of the device during use.
[0034] In other embodiments, the two ends of the return spring 14 are respectively connected to the inner wall of the bottom end of the guide slot 10 and the outer wall of the bottom end of the guide slider 11, and the guide slider 11 is elastically connected to the inner wall of the bottom end of the guide slot 10 through the return spring 14;
[0035] Through this design, the two groups of return springs 14 can continuously apply upward elastic force to the two groups of guide sliders 11, so that the two groups of guide sliders 11 can drive the two groups of limit plates 12 to move upward quickly.
[0036] The electrical components mentioned in this article are all connected to an external main controller and industrial power supply, and the main controller can be a conventional known device for control such as a computer.
