Description

Technical Field

[0001] The utility model belongs to the field of detection devices, and in particular relates to a real-time detection device for a gas extraction pipeline. Background Art

[0002] Gas extraction pipeline is a pipe system used to discharge gas. Gas, also known as natural gas, is a common energy source widely used in households, industries and commercial areas. However, gas will produce some harmful byproducts during use, such as carbon dioxide and carbon monoxide. In order to safely discharge these harmful gases, gas extraction pipelines are designed and installed.

[0003] Gas extraction pipelines are usually connected to gas supply pipelines. Harmful gases are extracted from equipment or buildings through the pipeline system and then discharged to a safe place, such as outdoor air or a specific treatment system. This can effectively reduce the concentration of harmful gases in the room and protect the health and safety of personnel.

[0004] However, the staff can only detect the flow rate and other data of the gas and other gas contents in the gas extraction pipeline at the discharge port of the gas extraction pipeline, which has poor timeliness. Therefore, it needs to be improved. Summary of the invention

[0005] The utility model aims to provide a real-time detection device for a gas extraction pipeline, which solves the problem that the staff can only detect the flow rate and other data of the content of gas and other gases in the gas extraction pipeline at the discharge port of the gas extraction pipeline, and the timeliness is poor.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a real-time detection device for a gas extraction pipeline, comprising a gas extraction pipe and a gas detector, wherein a mounting nozzle is fixedly connected to the middle section of the pipe body of the gas extraction pipe, a sealing gasket is embedded in the top of the mounting nozzle, a probe is arranged at the bottom of the gas detector, a pressure ring is fixedly connected to the middle section of the needle body of the probe, and the pressure ring is in contact with the sealing gasket, an internal threaded sleeve is slidably sleeved on the outer side of the needle body of the probe, the internal threaded sleeve is threadedly connected to the mounting nozzle, the internal threaded sleeve is in contact with the pressure ring, a hollow shell is fixedly connected to the upper end of the gas extraction pipe and located on the right side of the mounting nozzle, a slide is slidably connected to the interior of the hollow shell, a locking pin is fixedly connected to the left side of the upper end of the slide, and the locking pin is plugged into the internal threaded sleeve.

[0007] The principle of the utility model is that when in use, first press the push rod through the button, and the push rod pushes the slide plate downward, so that the locking pin on the slide plate moves downward synchronously, and then the probe of the gas detector is inserted into the gas extraction pipe through the installation nozzle. At this time, the pressure ring on the probe contacts the sealing gasket on the installation nozzle, and then the internal threaded sleeve is screwed on the installation nozzle. When the internal threaded sleeve is screwed into place, release the button, and the locking pin on the slide plate will be inserted into the internal threaded sleeve from the bottom under the action of the spring, so that the internal threaded sleeve can be locked and fixed, thereby ensuring the stability and sealing of the gas detector after installation, and then the gas detector can be used to perform real-time detection of the gas content and flow in the gas extraction pipe.

[0008] The beneficial effect of the utility model is that a threaded installation nozzle is arranged on the pipe body of the gas extraction pipe, and then a sealing gasket is embedded in the top of the installation nozzle. In addition, a fixed pressure ring and a movable internal thread sleeve are arranged on the probe of the gas detector. In this way, a gas detector can be installed on the gas extraction pipe by utilizing the threaded connection between the internal thread sleeve and the installation nozzle, so that the gas content and flow rate in the gas extraction pipe can be detected in real time.

[0009] By arranging a hollow shell, a slide plate, a locking pin, a push rod, a spring and other components on the gas extraction pipe and below the internal threaded sleeve, after the internal threaded sleeve is screwed into place, the locking pin on the slide plate will be inserted into the internal threaded sleeve from the bottom under the action of the spring, so that the internal threaded sleeve can be locked and fixed, thereby ensuring the stability and sealing of the gas detector after installation.

[0010] Furthermore, the sealing pad is annular and made of chloroprene rubber. The sealing pad has a sealing effect after the gas detector is installed.

[0011] Furthermore, a guide sleeve is fixedly connected to the inner side of the installation nozzle, a ball is arranged on the inner side of the guide sleeve, and the ball contacts the probe. The guide sleeve has a guiding effect on the probe of the gas detector being inserted into the installation nozzle.

[0012] Furthermore, a push rod is slidably connected inside the hollow shell, one end of the push rod abuts against the slide plate, and the other end of the push rod is fixedly connected to a button. The push rod can be pressed by the button to apply thrust to the slide plate.

[0013] Furthermore, a protective sleeve is fixedly connected to the bottom edge of the button, and the protective sleeve is fixedly connected to the hollow shell. The provision of the protective sleeve can prevent the button and the push rod from being lost.

[0014] Furthermore, a guide column is fixedly connected to the inner side of the hollow shell, the guide column passes through the slide plate and is slidably connected to the slide plate, and a spring is sleeved on the outer side of the column body of the guide column. The setting of the guide column has a guiding effect on the lifting and lowering of the slide plate.

[0015] Further, one end of the spring is fixedly connected to the slide plate, and the other end of the spring is fixedly connected to the inner surface of the hollow shell. Through the arrangement of the spring, the elastic force can be applied to the slide plate. BRIEF DESCRIPTION OF THE DRAWINGS
