Description

Technical Field

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

[0002] In the textile industry, dryers are an important and indispensable equipment. Dryers are used to dry and shape textiles after dyeing and finishing. Dryers currently on the market generally have multiple drying boxes installed in the dryer body. Textile fabrics are fed into the drying boxes from the dryer's fabric inlet, and then, after drying, are taken out from the dryer's fabric outlet, thus completing the drying and shaping process of the textile fabrics. However, a disadvantage of traditional dryers is that a large amount of water is generated during the drying process of the dyed and finished fabrics. The water will drip into the dryer body due to gravity, and a steam trap is installed on the outer side of the dryer body to discharge the water in the body through a pipe.

[0003] For example, a Chinese patent with announcement number CN205482219U discloses a special drain device for a textile dryer, comprising a machine body, a plurality of drying boxes installed inside the machine body, a cloth inlet and a cloth outlet installed on the machine body, a drain valve connected to the outer surface of the machine body, and the drain valve arranged on the side of the machine body. The invention is characterized in that at least two drying boxes are installed inside the machine body, a drying drum is installed inside the drying box, a water collecting tank is provided at the bottom of the drying box, each of the water collecting tanks is connected to a corresponding drain valve, each of the drain valves is connected to the drain valve on the outer surface of the machine body, the drain valve is installed inside the machine body, and the drain valve is connected to the drain valve on the outer surface of the machine body through a pipe.

[0004] Although the above technical solution solves the corresponding technical problem, it still has the following defects:

[0005] The steam trap of the above technical solution does not have the function of reducing pressure. In actual use, when the pressure inside the steam trap is relatively high, it is easy to cause the steam trap to burst, thereby reducing the service life of the steam trap. Utility Model Content

At the same time, by rotating the adjusting bolt and under the action of the thread of the threaded sleeve, the height of the adjusting pressure plate can be adjusted, thereby facilitating the adjustment of the compression degree of the telescopic spring. Therefore, the stroke of the sealing piston plate being compressed can be adjusted, and thus the pressure at which the sealing piston plate is compressed through the pressure reducing hole can be adjusted. Therefore, the pressure can be adjusted according to actual needs, thereby improving the practicality of the utility model.

[0036] Elastic telescopic components 403 are installed on both sides of the top of the sealing piston plate 402. Specifically, the elastic telescopic component 403 includes a telescopic shell 4031, the inner wall of which is fixedly connected to a telescopic spring 4032. The bottom of the telescopic spring 4032 is fixedly connected to a connecting slider 4033, and the bottom of the connecting slider 4033 is fixedly connected to a telescopic column 4034. The bottom of the telescopic column 4034 is fixedly connected to the top of the sealing piston plate 402.

[0037] An adjustable pressure plate 404 that can be raised and lowered is provided on the top of the elastic telescopic component 403 , and the bottom of the adjustable pressure plate 404 is fixedly connected to the top of the telescopic shell 4031 .

[0038] A threaded sleeve 405 is fixedly connected to the center of the top of the decompression housing 4 , and an adjusting bolt 4051 is threadedly connected to the threaded sleeve 405 .
