Abstract

The invention discloses a floating ball type drain valve rod and a double-valve-element assembly. The floating ball type drain valve rod comprises a valve rod body, a lower valve element, an upper valve element, a fastening assembly and a screw. The valve rod body comprises a middle section, an upper valve element mounting part, a lower valve element mounting part and a fastening assembly mountingpart. The outer wall of the lower valve element mounting part is provided with a first threaded section and a first smooth section in a wrapped manner, and the lower valve element is provided with alower valve element inner hole. The lower valve element inner hole comprises a third smooth section, a third threaded section and a fourth threaded section, the third threaded section and the fourth threaded section are located at the two ends and are large in inner diameter, the third threaded section is in threaded connection with the first threaded section, and the third smooth section corresponds to the first smooth section. A lower valve element conical face is arranged on the periphery of the lower valve element. The upper valve element comprises an upper valve element inner hole, the upper valve element mounting part penetrates into the upper valve element inner hole, and an upper valve element conical face is arranged on the periphery of the upper valve element. The fastening assembly limits the upper valve element between the fastening assembly and the middle section from the upper portion, the screw is fastened to the fourth threaded section, and the screw tightly jacks the lower end of the lower valve element mounting part. By means of the assembly, high assembling quality can be achieved conveniently.

Description

technical field [0001] The invention relates to the field of steam traps, in particular to a ball float type trap valve rod and a double valve core assembly. Background technique [0002] Float type double-spool steam trap consists of a float ball, a valve seat, a valve stem and two valve cores. The valve core is coaxially sleeved on the valve stem. Seats are open or sealed. The two valve cores are connected to the same valve stem, which requires extremely high precision of the valve core and the quality of assembly with the valve stem. If the degree cannot meet the requirements, the airtightness of the trap will be reduced. Contents of the invention [0003] Aiming at the defects of the prior art, the invention provides a ball float type steam trap valve rod and a double valve core assembly. [0004] Ball float trap stem and dual spool assembly, including: [0005] The valve stem, the valve stem includes a middle section, an upper spool installation part connected to ...
