Valve assembly with temperature detection function

Abstract

The utility model relates to the technical field of valve assembly equipment, in particular to a valve assembly with a temperature detection function, which comprises a valve pipe fitting, flange valve pipe fittings are symmetrically fastened by flange bolts at the left end and the right end of the valve pipe fitting, an electromagnetic valve is fixedly mounted at the upper end in the valve pipe fitting, and a temperature detection pipeline assembly is mounted between the upper sides of the front ends of the flange valve pipe fittings. A temperature measuring instrument is installed at the upper end of the temperature detection pipeline assembly.

Description

Technical Field

[0001] The utility model relates to the technical field of valve component equipment, in particular to a valve component with temperature detection. Background Art

[0002] A valve assembly with temperature detection generally refers to a valve device with integrated temperature detection function. This assembly combines the basic functions of the valve, such as fluid control, with the temperature detection function to facilitate real-time monitoring and control of the fluid temperature passing through the valve.

[0003] The temperature detection device commonly found in valve assemblies on the market usually directly inserts the temperature probe of the temperature testing instrument into the interior of the pipeline to directly contact and measure the temperature of the fluid. Since the temperature probe is in direct contact with the fluid for a long time, its durability will be corroded due to different fluid properties, resulting in damage to the temperature probe. Therefore, those skilled in the art provide a valve assembly with temperature detection to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a valve assembly with temperature detection, including a valve pipe fitting, wherein the left and right ends of the valve pipe fitting are symmetrically fastened with flange bolts to fasten the flange valve pipe fitting, an electromagnetic valve is fixedly installed on the upper end of the valve pipe fitting, a temperature detection pipeline assembly is installed between the upper sides of the front end of the flange valve pipe fitting, and a temperature measuring instrument is installed on the upper end of the temperature detection pipeline assembly;

[0005] The temperature inspection pipeline assembly includes a temperature inspection sleeve, a sealing partition, a temperature inspection cavity, an oblique pipeline, a pipeline cavity and a bolt seat. A sealing partition is fixedly installed in the middle of the temperature inspection sleeve, and the sealing partition divides the inner cavity of the temperature inspection sleeve into left-right symmetrical temperature inspection cavities. The lower end of the temperature inspection sleeve is fixedly installed with an oblique pipeline;

[0006] The temperature measuring instrument comprises a temperature measuring instrument body, a sealing pad, a bolt rod seat, a temperature detection head and a sealed temperature sensing kit. The temperature detection head is symmetrically arranged on the middle of the lower end surface of the temperature measuring instrument body.

[0007] Preferably, bolt seats are symmetrically fixed on the left and right ends of the temperature inspection sleeve.

[0008] Preferably, the oblique pipeline is obliquely connected to the flange valve pipe fitting through a bend, and the pipeline cavity in the inner cavity of the oblique pipeline is connected to the temperature detection cavity on the same side.

[0009] Preferably, a sealing gasket is fixedly installed along the edge of the lower end surface of the temperature measuring instrument body. The sealing gasket is made of soft rubber material and can effectively seal the temperature measuring instrument body and the temperature detection pipeline assembly to reduce liquid infiltration.

[0010] Preferably, bolt rod seats are fixedly installed at the left and right ends of the temperature measuring instrument body, and the bolt rod seats and the bolt seats are fastened with bolts, so that the temperature measuring instrument body is firmly installed on the temperature inspection sleeve to ensure the stability of the temperature measuring instrument body during working.

[0011] Preferably, the outer side of the temperature detection head is provided with a sealed temperature sensing kit, and the sealed temperature sensing kit contains mercury liquid.

[0012] Technical effects and advantages of the utility model:

[0013] 1. When the utility model is used, by closing the solenoid valve, the flange valve fittings on the left and right sides transmit the transmitted liquid through the pipe cavity in the oblique pipe into the temperature detection cavity. At this time, the transmitted liquid will conduct heat to the mercury liquid in the sealed temperature sensing kit, and then transfer the heat to the temperature detection head for detection, thereby preventing the temperature detection head from contacting the transmission liquid with different acidity and alkalinity, reducing the exposure of the temperature detection head to the inside of the pipe to be corroded, and increasing the service life.

[0014] 2. When the utility model is used, since the inclined pipeline is installed obliquely, after the actual transportation of the pipeline is completed, the temperature detection liquid in the pipeline cavity will flow back into the pipeline under the influence of gravity, so that the temperature measuring instrument will no longer contact the transmission liquid, preventing the occurrence of residual conditions that cause erosion.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0022] See also Figures 1 to 3 In this embodiment, a valve assembly with temperature detection is provided, including a valve pipe 1, wherein the left and right ends of the valve pipe 1 are symmetrically fastened with flanged valve pipes 2 by flange bolts, an electromagnetic valve 3 is fixedly installed on the upper end of the valve pipe 1, a temperature detection pipeline assembly 4 is installed between the upper sides of the front ends of the flanged valve pipe 2, and a temperature measuring instrument 5 is installed on the upper end of the temperature detection pipeline assembly 4;

[0023] The temperature inspection pipe assembly 4 comprises a temperature inspection sleeve 41, a sealing baffle 42, a temperature inspection cavity 43, an oblique pipeline 44, a pipeline cavity 45 and a bolt seat 46. The bolt seats 46 are symmetrically fixedly installed at the left and right ends of the temperature inspection sleeve 41. A sealing baffle 42 is fixedly installed in the middle of the temperature inspection sleeve 41. The sealing baffle 42 divides the inner cavity of the temperature inspection sleeve 41 into left and right symmetrical temperature inspection cavities 43. An oblique pipeline 44 is fixedly installed at the lower end of the temperature inspection sleeve 41. The oblique pipeline 44 is obliquely connected to the flange valve pipe fitting 2 through bending, and the pipeline cavity 45 of the inner cavity of the oblique pipeline 44 is connected to the temperature inspection cavity 43 on the same side.

[0024] The temperature measuring instrument 5 includes a temperature measuring instrument body 51, a sealing pad 52, a bolt rod seat 53, a temperature detection head 54 and a sealed temperature sensing kit 55. A sealing pad 52 is fixedly installed along the edge of the lower end surface of the temperature measuring instrument body 51. The sealing pad 52 is made of soft rubber material and can effectively seal the temperature measuring instrument body 51 and the temperature detection pipeline assembly 4 to reduce liquid infiltration. Bolt rod seats 53 are fixedly installed on the left and right ends of the temperature measuring instrument body 51. The bolt rod seats 53 and the bolt seats 46 are fastened with bolts to firmly install the temperature measuring instrument body 51 on the temperature detection sleeve 41 to ensure the stability of the working process of the temperature measuring instrument body 51. The temperature detection head 54 is symmetrically arranged on the left and right middle part of the lower end surface of the temperature measuring instrument body 51. The outer side of the temperature detection head 54 is provided with a sealed temperature sensing kit 55, and mercury liquid is stored in the sealed temperature sensing kit 55.

[0025] The working principle of the utility model is:

[0026] When the utility model is used, the solenoid valve 3 is closed, and the flange valve pipe fittings 2 on the left and right sides transmit the transmitted liquid through the pipe cavity 45 in the inclined pipe 44 into the temperature detection cavity 43. At this time, the transmitted liquid will conduct heat to the mercury liquid in the sealed temperature sensing kit 55, and then transfer the heat to the temperature detection head 54 for detection, thereby preventing the temperature detection head 54 from contacting the transmission liquid with different acidity and alkalinity properties, reducing the exposure of the temperature detection head 54 to corrosion inside the pipe, and increasing the service life. After completing the temperature detection, the corresponding liquid transmission is implemented. Since the inclined pipe 44 is installed obliquely, after the actual transportation of the pipeline is completed, the temperature detection liquid in the pipe cavity 45 will flow back into the pipeline under the influence of gravity, so that the temperature measuring instrument 5 will no longer contact the transmission liquid, preventing the occurrence of residual conditions that cause erosion.
