Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, and particularly relates to a temperature and pressure gauge connector. Background Art

[0002] The temperature and pressure gauge used in the heating pipeline of a household boiler and the water heater equipment is a device for monitoring the temperature and pressure of a working medium (such as water or other fluids), which can help users monitor and maintain the operation status of the equipment, and ensure the safe and efficient operation of the heating or hot water system.

[0003] After the temperature and pressure gauge is installed and used for a period of time, it needs to be overhauled again or a new temperature and pressure gauge needs to be replaced. However, when the measured pipeline and equipment are in a working state, they cannot be directly shut down or closed. Therefore, when replacing the temperature and pressure gauge, it needs to be replaced or overhauled while on standby. At this time, the working medium in the equipment is likely to spray out, affecting the working environment or scalding the staff. Content of the Utility Model

Detailed Embodiments

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0026] As Figures 1 - 3 shown, in one embodiment, a temperature and pressure gauge connector includes: a connector 1, which is installed on one side of a heating pipeline 2, and the connector 1 is used to connect the heating pipeline 2 and the temperature and pressure gauge 3;

[0027] Please continue to refer to Figures 1 - 3 , in this embodiment, the connector 1 includes an outer housing 11 and an inner housing 12, and the inner housing 12 is arranged inside the outer housing 11. Among them, multiple groups of sealing rings 13 are arranged inside the connector 1. The sealing rings 13 include a first sealing ring 131, a second sealing ring 132, and a third sealing ring 133, which are used to control the medium flow passage.

[0028] Exemplarily, the second sealing ring 132 is arranged between the first sealing ring 131 and the third sealing ring 133, and the inner diameter of the second sealing ring 132 is larger than that of the first sealing ring 131 and the third sealing ring 133, and the wire diameter of the third sealing ring 133 is larger than that of the first sealing ring 131 and the second sealing ring 132. It should be noted in detail that a spring 14 is arranged between the first sealing ring 131 and the second sealing ring 132, which can adjust the relative height of the inner housing 12 and the outer housing 11 before and after the installation of the temperature and pressure gauge 3, and then squeeze and loosen the first sealing ring 131.

[0029] Please continue to refer to Figures 1 - 3 , in this embodiment, a slope portion 111 is arranged at the bottom of the outer housing 11, and the slope portion 111 is used to squeeze the first sealing ring 131; a first accommodation portion 112 is arranged in the middle of the outer housing 11, and the accommodation portion is used to accommodate the spring 14.

[0030] Furthermore, a first groove portion 121 is arranged at the bottom of the inner housing 12, and the first sealing ring 131 is clamped in the first groove portion 121; a second groove portion 122 is arranged in the middle of the inner housing 12, and the second sealing ring 132 is clamped in the second groove portion 122; a second accommodation portion 123 is arranged at the top of the inner housing 12, and the third sealing ring 133 is arranged in the second accommodation portion 123.

[0031] Working principle: Before installing the temperature and pressure gauge 3, first install the connector 1 on the heating pipeline 2. Under the action of the spring 14, the slope portion 111 of the outer housing 11 squeezes the first sealing ring 131 on the first groove portion 121 of the inner housing 12, and seals through the first sealing ring 131 at the bottom to prevent the medium of the heating pipeline 2 from flowing out; subsequently, install the temperature and pressure gauge 3. After the spring 14 is compressed, the channel of the slope portion 111 of the outer housing 11 is opened, and seals through the second sealing ring 132 in the middle and the third sealing ring 133 at the top to prevent the medium from flowing out.

[0032] Through the above technical solution, the present application enables the heating equipment to be in a working state, and the temperature and pressure gauge 3 can also be replaced and repaired without the need to stop the machine for operation, nor will there be any outflow of the heating medium, effectively improving the work efficiency and operation safety.
