Abstract
The utility model discloses an extension gate valve life device, it is formed by connecting valve rod, valve plate, longmen checkpost, and the valve rod is fixed on the valve plate by longmen checkpost, there is a valve rod cross slot in one side of valve plate, has two in longmen checkpost groove at the interior edge of valve rod cross slot, the opposite side of valve plate is the circular arc, longmen checkpost is the U type. It has overcome the shortcoming that other techniques exist, can prolong gate valve life.
Description
Technical field
The utility model relates to can extend gate valve technology in working life, especially a kind of prolongation gate valve device in working life.
Background technique
Melamine crystallizer system is divided into A, B, C tri-, two open one standby.Every platform crystallizer terminal valve two, switches once for six days.Often switch primary crystallization device, four deck valve doors all want switch once, and on-off ratio is comparatively frequent, the serious wear of valve head and valve body, excesssive gap.Often switch primary crystallization device, in switching process, valve head all can come off, and causes crystallizer valve to use.In no matter daytime or evening, maintainer will overhaul valve.
Summary of the invention
The purpose of this utility model is to provide simple, the easy to operate one of a kind of structure and extends gate valve device in working life, which overcome the shortcoming that other technology exists, the purpose of this utility model realizes like this, it is formed by connecting by valve rod, valve plate, gantry clamp, and valve rod is fixed on valve plate by gantry clamp.There is valve rod translot in the side of valve plate, the inner edge of valve rod translot has gantry clamp groove two; The opposite side of valve plate is circular arc; Gantry clamp is U-shaped.
Meaning of the present utility model is: the working life extending valve, greatly reduces the expense changing valve.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation extending gate valve device in working life, in figure 1, valve rod 2, gantry clamp 3, valve plate
Fig. 2 is the structural representation of gantry clamp.
Embodiment
Embodiment 1, the utility model are formed by connecting by valve rod 1, gantry clamp 2, valve plate 3, and valve rod 1 is fixed on valve plate 3 by gantry clamp 2.
Embodiment 2, there is valve rod translot in the side of valve plate 3, the inner edge of valve rod translot has gantry clamp 2 groove two; The opposite side of valve plate 3 is circular arc; Gantry clamp 2 is U-shaped.
For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, make some equivalent to substitute or obvious modification, and performance or purposes identical, all should be considered as belonging to protection domain of the present utility model.
