DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the present technical solution clearer and more comprehensible, the present technical solution will be further described in detail below in combination with specific embodiments. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present technical solution.

[0023] In order to solve the problem that the sensor cannot be installed inside the breathing valve in the prior art, especially the opening position of the external protection gas cannot be installed with the sensor, as shown in Figure 1 The present embodiment proposes an integrated breathing valve with an online detection interface device, which comprises a valve body 1, the lower part of the valve body 1 has a connecting section 2, and the end of the connecting section 2 is a flange structure 3. In the present embodiment, the upper part of the valve body 1 can be installed with a valve cover, the inside of the valve body has a valve seat structure, the valve seat is installed with a valve disc correspondingly, and the side of the valve body has an opening communicating with the atmosphere. The internal structure of the above-mentioned valve body 1 is a conventional structure. In other embodiments, the internal structure of the valve body 1 can be changed adaptively according to the actual working condition requirements.

[0024] In the present embodiment, an inner opening 21 extending in the circumferential direction is formed on the connecting section 2, and the extension angle of the inner opening 21 can be between 160°-190°.

[0025] An external protection gas pipeline 4 is arranged outside the connecting section 2 and corresponds to the inner opening 21, the main body of the external protection gas pipeline 4 is a flat tubular structure, and a flange is arranged at the outer side of the pipeline 4. The external protection gas pipeline is connected around the connecting section 2, so that a cavity with a ring shape is formed between the connecting section 2 and the external protection gas pipeline 4, and the external protection gas pipeline 4 correspondingly forms a gas distribution pipeline 44. The cavity, the main body inside the external protection gas pipeline 4, and the inner opening 21 are all in communication.

[0026] As shown in Figures 1-4 In the present embodiment, the mounting positions for installing the sensor include a first mounting position 41 arranged on the first side of the external protection gas pipeline 4. The mounting positions also include a second mounting position 42 arranged on the second side of the external protection gas pipeline 4, and the second mounting position 42 is opposite to the first mounting position 41. The mounting positions also include a third mounting position 43 mounted on the second side of the external protection gas pipeline 4, and the second mounting position 42 and the third mounting position 43 are vertically parallel. Part or all of the mounting positions can be used as an online detection interface device.

[0027] In a feasible embodiment, the concentration sensors for monitoring the concentration of the protective gas are arranged at the first mounting position 41 and the second mounting position 42 respectively, and the state of the gas communication of the external protective gas pipeline 4 can be detected by the concentration sensors. For example, the concentration of the protective gas is detected when the external protective gas is not needed, or the consistency of the gas is detected when the external protective gas is needed. The sensors for detecting the impurity gas or harmful gas can be arranged at the third mounting position 43.

[0028] The sensors arranged at the first mounting position 41, the second mounting position 42 and the third mounting position 43 are only examples, and are not intended to limit the types of sensors. In the embodiment, the mounting positions are cylindrical structures protruding outward, i.e. the cylindrical cavities.

[0030] For example, when the organic gas filtering gel filter box needs to be installed at the external flange of the external protective gas pipeline 4, the gel filter box can be inserted and mounted into the accessory mounting position 45 by the buckle on the gel filter box from the outside of the port of the external protective gas pipeline 4, and the installation and disassembly are very convenient.

[0031] As shown in Figure 5 , in some feasible embodiments, a detachable gas flow guide cover 5 can be arranged on the breathing pipe opened on the side surface of the valve body 1. Since the gas flow guide cover can be detached, the filter device can be arranged on the breathing pipe opened on the side surface of the valve body 1, and the filter device can be conveniently maintained.
