Description

Technical Field

[0001] The utility model relates to the technical field of fluid measurement, in particular to an insertion-type electromagnetic flowmeter. Background Art

[0002] An electromagnetic flowmeter is a device used to measure the flow of conductive liquids.

[0003] A search revealed a Chinese utility model patent publication numbered CN220649622U, which discloses an electromagnetic flowmeter comprising a measuring pipe, a detection assembly, and at least one power supply assembly. The measuring pipe has at least one mounting slot defined therein; the detection assembly is disposed on the measuring pipe and is used to measure the flow rate of the fluid within the pipe; the power supply assembly comprises an impeller structure and a generator, the impeller structure being disposed within the mounting slot, with a portion of the impeller structure extending outside the slot; the generator being connected to the impeller structure, and the generator being electrically connected to the detection assembly. Since only a portion of the impeller structure is exposed outside the slot, the fluid can only impact a portion of the impeller structure, thereby reducing the kinetic energy lost by the fluid impacting the entire impeller structure and thereby improving the measurement accuracy of the electromagnetic flowmeter.

[0004] However, the device often lacks a quick connection function, which makes it inconvenient to quickly connect the flow meter body and the external pipeline during use, resulting in reduced convenience. Moreover, the device also lacks filtering and pressure relief functions, making it difficult to filter impurities inside the fluid during use, and difficult to pressure relief the fluid inside the input pipeline, resulting in damage to the flow meter body. Utility Model Content

[0005] The purpose of the present utility model is to provide an insertion type electromagnetic flowmeter to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An insertion electromagnetic flowmeter comprises a flowmeter body, one end of the flowmeter body is through-connected with an output pipe, the other end of the flowmeter body is through-connected with an input pipe, one end of each of the input pipe and the output pipe is through-connected with an insertion component, the insertion component comprises a fixing ring, one end of each of the fixing rings is through-connected to one end of the input pipe and the output pipe, a pressure relief component is fixedly connected to the middle of the top surface of the input pipe, the pressure relief component comprises a pressure relief pipe, the bottom of the pressure relief pipe is fixedly connected to the middle of the top surface of the input pipe, one end of the top surface of the input pipe is fixedly connected to a filter component, the filter component comprises a filter block, the bottom of the filter block is fixedly connected to one end of the top surface of the input pipe.

[0008] Preferably, the insertion component also includes a spring, one end of which is fixedly connected to the surface of the fixed ring, and sliding grooves are provided at the top and bottom of the fixed ring. The internal sliding connection of the sliding groove is a limiting ball, and one end of the spring is fixedly connected to a pressing ring.

[0009] Preferably, the inner top and the inner bottom of the pressing ring are provided with limiting grooves, the interior of the limiting grooves is fixedly connected to the limiting blocks, the interior of the pressing ring is slidably connected to the external tube, the top and the bottom of the external tube are provided with external holes, and the bottom of the limiting ball is clamped to the inside of the external hole.

[0010] Preferably, the pressure relief assembly further comprises a rubber ring, the surface of the rubber ring is fixedly connected to the inner bottom of the pressure relief pipe, and a plurality of groups of pressure relief holes are opened on the top of the surface of the pressure relief pipe.

[0011] Preferably, a pressure relief ball is slidably connected to the interior of the pressure relief pipe, and the bottom of the pressure relief ball is arranged on the top of the rubber ring.

[0012] Preferably, the filter assembly further comprises a filter tank, the top of the filter tank is opened at the top of the filter block, a filter frame is clamped inside the filter tank, a filter layer is fixedly connected inside the filter frame, and a convenient block is fixedly connected to the top of the filter frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This insertion-type electromagnetic flowmeter is provided with an insertion component. When in use, the staff moves the pressing ring backward according to the needs of the use scenario, and the spring is subjected to force. The surface of the limit block and the surface of the sliding groove are limited. The limit ball can move up and down inside the sliding groove. The external tube is inserted into the pressing ring. One end of the external tube will press against the limit ball and move upward. When the external tube moves to a certain position, the bottom of the sliding groove contacts the top of the external hole, and the bottom of the limit ball is stuck in the inside of the external hole. When the pressing ring is released, the spring drives the pressing ring and the limit block to rebound, so that the surface of the limit block contacts the top of the sliding groove, and the limit ball is limited, so as to achieve the effect of quickly inserting and connecting the external tube and the flowmeter body, thereby improving convenience.

[0015] 2. This insertion-type electromagnetic flowmeter is provided with a pressure relief component and a filter component. When in use, the staff aligns the filter frame with the inside of the filter tank and inserts it, so that the filter layer filters the water flow inside the input pipe, preventing impurities in the water flow from causing errors in the measurement results of the flowmeter body. The flowmeter body can also be pressure-relieved by the action of the pressure relief component. When the water pressure inside the input pipe is too high, the water flow will move upward against the pressure relief ball and discharge the excess water to the outside through several groups of pressure relief holes until the water pressure returns to normal. The pressure relief ball falls downward and contacts the rubber ring, blocking the bottom of the pressure relief pipe and the top of the input pipe, thereby preventing the pressure from being released when the water pressure increases abnormally and damaging the flowmeter body.
