Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating pipeline leakage prevention, in particular to a heating pipeline leakage prevention device. Background Art
[0002] As we all know, the temperature in the north is low and the air is dry in winter. In order for people in the north to live and work in this environment, some necessary warming measures need to be taken. At present, the northern region generally adopts centralized heating for heating. The hot water is mainly delivered to various residential areas and enterprises by thermal power plants through heating pipes. Therefore, the heating pipes also directly affect the safety and convenience of users. Once the heating pipes leak, it will have a greater impact on the daily life of users. The more common heating pipe leaks are at the joints of two heating pipes. Generally, the joints of heating pipes are connected by flanges or welding, and the sealing effect is average, which is not convenient for later maintenance and installation.
[0003] In response to the above problem, a Chinese patent announcement with announcement number CN212298000U discloses a heating pipe leakage prevention device, the technical points of which are: it includes a connecting pipe and a flexible sealing ring. When the heating pipe is assembled, the splicing area of the heating pipe is first placed in the middle external thread area of the connecting pipe, and then a fastening nut is tightened on each locking area. At this time, the tight locking area is squeezed inward by the fastening nut to squeeze the rubber sealing ring arranged in the connecting pipe. The rubber sealing ring is squeezed by the locking area to fit tightly against the heating pipe, so that the splicing of the heating pipe has better waterproof sealing. When the heating pipe leaks, hot water fills the detection cavity to push the baffle to compress the spring, so that the sensor senses the pressure and then sounds an alarm.
[0004] In actual operation, it is found that the above scheme still has at least the following defects: the joints of the heating pipes have low mechanical strength and are prone to deformation and damage, resulting in leakage of the heating pipes. Therefore, we propose a heating pipe leakage prevention device to solve the above problems. Utility Model Content
