Description

Technical Field

[0001] The utility model relates to the technical field of liquid level transmitters, in particular to a liquid level transmitter with a flow diversion effect. Background Art

[0002] The liquid level transmitter is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses an isolated diffused silicon sensitive element or a ceramic capacitor pressure sensitive sensor to convert the static pressure into an electrical signal, which is then converted into a standard electrical signal after temperature compensation and linear correction. The liquid level transmitter is also used to detect liquids in pipelines. Generally, the sensor is placed in the pipeline for detection.

[0003] The existing Chinese patent publication number is CN204388957U, which discloses a liquid level transmitter, which includes a gas collecting pipe with a cavity inside and a transmitter head connected to the gas collecting pipe, a pressure sensor diaphragm is installed at the upper end of the gas collecting pipe, and the pressure sensor diaphragm is located between the cavity and the transmitter head, the top of the base is threadedly connected to the bottom of the gas collecting pipe, an elliptical pre-storage cavity is opened in the middle of the base, and two longitudinal liquid inlet holes parallel to the gas collecting pipe are opened at the upper end of the base, the bottom of the pre-storage cavity is connected to the outside through the longitudinal liquid inlet holes, and transverse liquid inlet holes connected to the pre-storage cavity are obliquely arranged on both sides of the base, one end of the transverse liquid inlet hole points to the center of the pre-storage cavity, and the other end of the transverse liquid inlet hole points to the bottom of the liquid storage container. The utility model greatly increases the stability of the gas collecting pipe in the liquid storage container by lowering the center of gravity of the liquid in the pre-storage cavity. When the above-mentioned liquid level transmitter is actually used, since the space inside the pipeline is usually relatively narrow when the sensor of the liquid level transmitter is detecting in the pipeline, when the valve at one end of the pipeline is opened, the pipeline will be instantly filled with liquid, and the flow rate is too fast, and a concentrated impact force will directly impact the sensor, which may easily cause the sensor to be damaged due to the large impact force of the water flow, resulting in large fluctuations in the measured data, causing errors in the detection results and affecting the final use effect.

[0004] For this purpose, we propose a liquid level transmitter with diversion effect. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a liquid level transmitter with a flow diversion effect, which overcomes the above technical problems or at least partially solves the above problems.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a liquid level transmitter with a diversion effect, comprising a main pipeline and a liquid level transmitter body connected to the top thereof, a connecting ring is embedded in the inner wall of the end of the main pipeline away from the liquid level transmitter body, the inner wall of the connecting ring is connected to a slow flow tube, the slow flow tube is arranged inside the main pipeline, a baffle is connected to one side of the inner wall of the slow flow tube, a plurality of diversion holes are opened at the end of the slow flow tube away from the main pipeline, each of the diversion holes is connected to a spiral diversion tube, and a plurality of water outlet holes are spaced apart at the end of the slow flow tube away from the main pipeline.

[0007] As a preferred technical solution of a liquid level transmitter with a flow diversion effect of the utility model, one end of the main pipeline away from the liquid level transmitter body is connected to a connecting pipeline, and a valve is connected to the top of the connecting pipeline.

[0008] As a preferred technical solution of a liquid level transmitter with a flow diversion effect of the utility model, a groove is provided on the inner wall of one end of the main pipeline away from the liquid level transmitter body, and the connecting ring is clamped in the interior of the groove.

[0009] As a preferred technical solution of a liquid level transmitter with a flow diversion effect of the utility model, a sealing ring is connected to one end of the connecting ring, and an annular groove matching the sealing ring is provided in the groove.

[0010] As a preferred technical solution for a liquid level transmitter with a diversion effect of the utility model, a plurality of locking screws are provided in a ring at the other end of the connecting ring, and a plurality of threaded holes are equidistantly provided in a ring inside the annular groove. One end of each locking screw passes through the connecting ring and the sealing ring and is threadedly connected to the corresponding threaded hole.

[0013] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0014] 1. The liquid is initially blocked and intercepted by the slow-flow tube and the baffle plate to prevent the liquid from concentrated and rapid impact on the liquid level transmitter body. The liquid is intercepted again by one end of the slow-flow tube. At the same time, the concentrated liquid is dispersed into multiple streams of liquid by using multiple diversion holes, and flows synchronously into multiple spiral diversion tubes. The setting of multiple spiral diversion tubes further reduces the flow rate of the liquid and prevents the liquid from directly rushing into the liquid level transmitter body. The liquid flows slowly in the main pipeline through multiple spiral diversion tubes, which facilitates the normal operation of the liquid level transmitter body, thereby achieving the effect of diverting the concentrated liquid and slowing down the flow rate, and avoiding the concentrated impact of the liquid causing damage to the liquid level transmitter body;

[0015] 2. By using the connecting ring, sealing ring, annular groove and groove together, when the connecting ring is clamped in the groove of the main pipe, the sealing ring increases the sealing of the connection between the connecting ring and the main pipe, preventing liquid from flowing out from the gap between the two, effectively avoiding liquid leakage.

[0026] In other embodiments, one end of the main pipeline 1 away from the liquid level transmitter body 2 is connected to a connecting pipeline 3, and a valve 4 is connected to the top of the connecting pipeline 3. When the valve 4 is opened, the liquid will instantly fill the connecting pipeline 3 and rush into the inside of the main pipeline 1.

[0027] In other embodiments, a groove 13 is provided on the inner wall of the main pipe 1 away from the liquid level transmitter body 2 , and the connecting ring 5 is snapped into the groove 13 . The groove 13 is used to install the connecting ring 5 on the inner wall of the main pipe 1 .

[0028] In other embodiments, a sealing ring 6 is connected to one end of the connecting ring 5, and an annular groove 14 matching the sealing ring 6 is opened in the groove 13. The sealing ring 6 increases the sealing performance of the connection between the connecting ring 5 and the main pipeline 1 to prevent liquid from flowing out from the gap between the two.

[0029] In other embodiments, a plurality of locking screws 7 are provided in a ring shape at the other end of the connecting ring 5, and a plurality of threaded holes 15 are equidistantly provided in a ring shape inside the annular groove 14. One end of each locking screw 7 passes through the connecting ring 5 and the sealing ring 6 and is threadedly connected to the corresponding threaded hole 15.

[0030] In other embodiments, a first connecting flange 16 and a second connecting flange 17 are respectively connected on the outer walls of one end of the main pipeline 1 and the connecting pipeline 3.
