Description

Technical Field

[0001] The utility model belongs to the field of air flow pipeline valves, and particularly relates to a negative pressure introduced external air flow pipeline valve. Background Technique

[0002] As a control component in a fluid transportation system, the functions and types of air flow pipeline valves are quite diverse. From the simplest stop valve to various valves used in extremely complex automatic control systems, there is a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as water, steam, oil products, gases, mud, various corrosive media, liquid metals, and radioactive fluids, and can adapt to various extreme working conditions. However, there are deficiencies in the use of air flow pipeline valves: 1. Ordinary air flow pipeline valves need to manually adjust the pipeline to connect or disconnect the pipeline from the outside, which is not convenient to use and time-consuming and laborious; 2. During the actual use of air flow pipeline valves, the temperature inside the pipe cannot be understood in real time, and it is necessary to manually judge the temperature and open or close the connection between the air flow pipeline and the outside according to the temperature. When used, it is more labor-intensive and material-consuming, and it is easy to cause inaccurate temperature data. Content of the Utility Model

[0003] In view of the above, the utility model provides a negative pressure introduced external air flow pipeline valve to solve the problems raised in the above background technique.

Detailed Embodiment

[0014] The following further describes the present utility model in conjunction with the drawings and some embodiments.

[0015] In Figures 1 - 3In this case, a negative pressure-introducing external air flow pipeline 1 valve includes an air flow pipeline 1. The air flow pipeline 1 includes an inner pipe 101 and an outer pipe 103. The inner pipe 101 is placed inside the outer pipe 103. The diameters of the inner pipe 101 and the outer pipe 103 differ by 3 millimeters. The 3-millimeter difference enables the inner pipe 101 to be just placed inside the outer pipe 103, allowing it to move while not preventing the inner pipe 101 and the outer pipe 103 from rotating. A number of inner holes 102 are provided on the inner pipe 101, and a number of outer holes 104 are provided on the outer pipe 103. The positions of the inner holes 102 correspond one by one to the positions of the outer holes 104. When the inner holes 102 coincide with the outer holes 104, external air flow can be introduced to dilute the high temperature inside the pipe. When the inner holes 102 and the outer holes 104 overlap and are staggered, the external air flow is blocked. A detection assembly 2 is provided at the bottom end of the air flow pipeline 1. It includes a temperature sensor 201 for checking the temperature of the inner pipe 101 and a push-pull assembly 202 for rotating the air flow pipeline 1. The output end of the temperature sensor 201 is connected to the input end of the push-pull assembly 202. The temperature sensor 201 is located inside the inner pipe 101. One end of the push-pull assembly 202 is fixedly connected to the outer end face of the inner pipe 101, and the other end is fixedly connected to the inner end face of the outer pipe 103. The push-pull assembly 202 includes a slidable slide rail 203, a motor 206 for driving the slide rail 203 to move, and a microcontroller 207. The temperature sensor 201 is connected to the input end of the microcontroller 207, and the signal control end of the motor 206 is connected to the output end of the microcontroller 207. The threshold value of the temperature sensor 201 can be set through the microcontroller 207 according to actual needs. When the temperature inside the air flow pipeline 1 is too high, the temperature sensor 201 transmits a signal to the microcontroller 207. The microcontroller 207 receives the signal and sends it to the motor 206. Subsequently, the motor 206 drives the slide seat 204 to slide on the guide rail 205, aligning the inner holes 102 with the outer holes 104 to introduce external air flow to dilute the high temperature inside the pipe. Similarly, when the temperature inside the air flow pipeline 1 reaches below the set temperature, the motor 206 drives the slide seat 204 to move so that the inner holes 102 and the outer holes 104 overlap to block the external air flow.

[0016] In this embodiment, the slide rail 203 includes a slide seat 204 and a guide rail 205. The slide seat 204 is fixedly connected to the outer pipe 103, and the guide rail 205 is fixedly connected to the inner pipe 101. The slide seat 204 and the guide rail 205 cooperate with each other to slide, enabling the inner pipe 101 and the outer pipe 103 to rotate through the slide rail 203. The sliding of the slide seat 204 on the guide rail 205 is divided into two parts. One is to slide to align the inner holes 102 with the outer holes 104 to introduce external air flow, and the other is to slide back to overlap the inner holes 102 with the outer holes 104 to isolate the external air flow.

[0017] In this embodiment, the slide rail 203 is integrally in an arc shape that fits the outer pipe 103 and the inner pipe 101, making the sliding smoother and more convenient.

[0018] In this embodiment, a switch 105 is provided on the air flow pipeline 1. The output end of the switch 105 is connected to the input end of the microcontroller 207, and the motor 206 and the temperature sensor 201 are controlled to work or stop working through the switch 105.

[0019] In this embodiment, a power cord 106 connected to an external power supply is provided on the air flow pipeline 1. The output end of the power cord 106 is connected to the input end of the switch 105, and the switch 105 is respectively connected to the motor 206 and the temperature sensor 201 through the microcontroller 207. Electrical energy is provided for the switch 105, the microcontroller 207, and the motor 206 through the power cord 106.

[0020] In this embodiment, the microcontroller 207 is a common electrical component, such as a single-chip microcomputer of the AT89C2051 or TMS320VC5509A model.

[0021] In this embodiment, the temperature sensor 201 is a common temperature sensor device, such as a WS90501-N model sensor, a KNE-WZP model sensor, etc.

[0022] In this embodiment, the motor 206 is a common linear motor device, such as a 25BYZ series linear motor.

[0023] In this embodiment, the control circuit of the present utility model is a common circuit in the circuit field. The device of the present utility model can be connected to an external power supply or an internal battery through a power cord to provide electrical energy for the device, which can be realized by those skilled in the art and will not be elaborated here.

[0024] When the present utility model is specifically implemented: during use, the power is turned on through the power cord 106, and the switch 105 is turned on to make the temperature sensor 201 and the motor 206 in a working state. When the temperature in the air flow pipeline 1 is too high, the temperature sensor 201 transmits a signal to the microcontroller 207. The microcontroller 207 receives the signal and sends it to the motor 206. Subsequently, the motor 206 drives the slide 204 to slide on the guide rail 205, aligning and overlapping the inner hole 102 and the outer hole 104, so that the negative pressure in the pipe introduces external air flow to dilute the high temperature in the pipe; similarly, when the temperature in the air flow pipeline 1 reaches below the set temperature, the motor 206 drives the slide 204 to move so that the inner hole 102 and the outer hole 104 overlap to block the external air flow.
