Abstract

The invention discloses a steam trap valve for a tire vulcanizing machine. An auxiliary valve body is welded to the lower portion of a valve lid and composed of an auxiliary valve piece, an auxiliary valve lid and an auxiliary valve passage; and the auxiliary valve piece is arranged in a cavity formed by connecting the auxiliary valve body and the valve lid, an insulation cover is fixedly mounted below the auxiliary valve body, and a floating ball is arranged below the insulation cover and supported through a plurality of guiding columns. According to the steam trap valve for the tire vulcanizing machine, the structure is simple, and using is convenient; by adopting a novel multi-guiding-column structure, multi-point positioning is formed in the floating ball sealing process, and under the effect of multi-point positioning, alignment of the floating ball in the sealing process is accurate, so that the problems that the valve is not completely opened or closed, thus the air leakage quantity is large, and the sealing performance is instable are solved; and by arranging the structure of the auxiliary valve body, the effects that body cavity air is rapidly and effectively exhausted, starting and stopping of the floating ball are rapid and accurate, and the water discharge quantity is large are achieved, and the problems that the requirements for all working conditions cannot be met, and as sealing of the valve is not tight, steam leakage is caused and thus air resistance and water discharge cannot be achieved are avoided.

Description

technical field

[0001] The invention relates to the field of tire manufacturing, in particular to a steam trap for a tire vulcanizer. Background technique

[0002] The normal operation of the steam trap greatly affects the performance and efficiency of the vulcanizing machine in the tire manufacturing process. At the same time, it also affects the service life of the equipment, and sometimes brings unexpected vicious accidents, causing huge losses to the enterprise. Therefore, it is very important to choose a good trap.

[0003] In the existing free float trap, under actual working conditions, the medium in the valve cavity is a two-phase mixture of high-temperature steam and high-temperature condensed water, and its dynamic changes make the float unstable, and the trap will be in a state of being open. In the seemingly closed state, the opening and closing action of the trap is not obvious, and the steam (gas) leakage of the trap is relatively large, which has the problem...
