Description

Technical Field

[0001] The utility model relates to the technical field of thermal steam traps, in particular to a composite thermal steam trap. Background Art

[0002] A thermal steam trap is a device that automatically removes condensate from steam systems such as steam pipes and heating equipment. It operates primarily by relying on the temperature difference between steam and condensate. When condensate enters the trap, its lower temperature causes the temperature-sensing element inside the valve to contract or deform, thereby opening the valve and allowing the condensate to drain. When steam enters, its higher temperature causes the temperature-sensing element to expand or return to its original shape, closing the valve and preventing steam leakage.

[0003] After searching, the applicant discovered a Chinese patent application titled "CN2073527U," with the publication (announcement) number "Thermal Steam Trap." This patent primarily describes a thermal steam trap comprising a valve body, valve core, bonnet, and plug. The improved design features a disc-shaped valve core, a valve core rod, and a valve core tail with guide wings. The upper end of the valve core rod is riveted to the center hole of the valve core disc, while the lower end is statically fitted with the valve core tail, giving the entire valve core a standing mushroom shape. This utility model overcomes the shortcomings of conventional steam traps, such as high leakage rates and short lifespans, making it suitable for steam-blocking and draining water from various steam heating equipment. However, this patent does not filter the incoming fluid. Therefore, we propose a composite thermal steam trap. Utility Model Content

[0011] The technical effects and advantages of this utility model are:

[0012] 1. Through the provided filtering mechanism, the filter disc is placed in the filter tube through the filter screen placement strip provided on the circumferential surface of the filter tube. The filter screen on the filter tube and the filter disc cooperate with each other, and the filter screen can intercept the debris in the fluid to be transported and uniformly pile it into the debris placement port.

[0023] Specifically, the filter disc 51 is placed in the filter tube 57 through the filter screen placement strip 56 provided on the circumferential surface of the filter tube 57. The filter screen 58 cooperates with the filter tube 57 to intercept debris in the fluid to be transported.

Example 2

[0024] Please see the attached Figure 1 - Attachment Figure 5 , and on the basis of Example 1, it is further obtained that a water stop mechanism 6 is fixedly connected to the right side of the valve pipe 2, the water stop mechanism 6 includes a water stop pipe 63, a water stop valve 62 is provided in the middle position of the water stop pipe 63, a water stop switch 61 is provided on the top of the water stop valve 62, a rotating rod 65 is fixedly connected below the water stop switch 61, and a water stop block 64 is fixedly connected to the lower surface of the rotating rod 65.
