Upside-down bucket type drain valve with universal joint

Abstract

The invention relates to an upside-down bucket type drain valve with a universal joint. The drain valve comprises a valve body, adjusting units and a hoisting unit. The adjusting units are symmetrically arranged in the middle of the lower end of the valve body in a front and back manner, and the hoisting unit is installed at the upper end of the valve body in a sliding fit manner. The upside-downbucket type drain valve with the universal joint is installed according to the design concept of combining adjusting structures at multiple angles, the arranged adjusting units can enable the valve body and pipelines at multiple angles or in different directions to be in butt joint, and therefore the diversity the overall functions of the drain valve is greatly improved, and the application rangeof the drain valve is greatly broadened; and a structure capable of improving the rotating smoothness of a main rotating structure is additionally arranged in each adjusting unit, so that user experience with the drain valve can be improved, and meanwhile, with the hoisting unit, it can be implemented that the valve body can be quickly hoisted and can be independent disassembled after being hoisted.

Description

technical field [0001] The invention relates to the technical field of steam trap installation, in particular to a universal joint inverted bucket type steam trap. Background technique [0002] Inside the inverted bucket trap is an inverted bucket as a liquid level sensitive part. The opening of the bucket is downward, and the lever connecting the inverted bucket drives the valve core to open and close the valve. The inverted bucket trap can exhaust air, is not afraid of water hammer, and has good anti-pollution performance. The steam trap plays the role of blocking steam and draining water in the steam heating system. Choosing a suitable trap can make the steam heating equipment achieve the highest working efficiency. The inverted bucket trap can resist high pressure and water hammer. After installing the inlet and check valve , can be used in superheated steam systems, and its failure mode is usually normally open. Applications that require this feature are safer, such as ...

AI Technical Summary

Problems solved by technology

[0003] 1. Most of the connection ends between the common steam traps and pipelines are fixed structures, that is, they cannot be rotated or adjusted at multiple angles, and then the adaptability to the connection of multi-form pipelines is relatively low, while the structure of the rotatable connection ends of a few steam traps is relatively poor. Single, and there is no shielding structure on the outside, so that impurities such as dust can easily enter the connection gap, and the overall smoothness of rotation is low;

[0004] 2. The structure of the auxiliary steam trap installation has low variability, so that the adaptability to the installation requirements of the steam trap is low. On this basis, the steam trap is only installed by hoisting or ground installation, and at the same time, the rotatable connection of the connection end is ignored. The damping valve is equipped with a shock-absorbing structure, which causes the rotating structure to be easily deformed due to external factors
