Description
Technical field
This utility model relates to valve field, particularly to a kind of spring hydraulic butterfly valve.
Background technology
Existing hydraulic butterfly valve, include valve body, valve rod, valve body is provided with medium runner, flap it is provided with in medium runner, valve rod lower end is linked with flap, it is additionally provided with the hydraulic cylinder opened by valve for controlling valve rod to rotate forward on valve body and is used for controlling valve rod and rotates backward the gravity drop hammer of valve closing, when dead electricity, the effect of gravity drop hammer can be relied on to be automatically switched off by valve.But, the hydraulic butterfly valve of this structure, its volume is big, takes up room big, and the closing velocity of valve is slow.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, this utility model provides a kind of spring hydraulic butterfly valve, and its volume is little, takes up room little, and the closing velocity of valve is faster.
The technical solution of the utility model: a kind of spring hydraulic butterfly valve, include valve body, valve rod, valve body is provided with medium runner, flap it is provided with in medium runner, valve rod lower end is linked with flap, valve body is provided with the hydraulic cylinder opened by valve for controlling valve rod to rotate, it is characterised in that: it is additionally provided with the spring of valve closing on described valve body for the valve rod that automatically resets.
Using technique scheme, being automatically reset by valve rod by spring realizes the closedown of valve, and the volume so making hydraulic butterfly valve is little, takes up room little, and the closing velocity of valve is faster.
Further setting of the present utility model: described valve rod upper end is arranged with gear, valve rod coordinates with gear-linked, valve body is provided with casing, tooth bar it is provided with in casing, wheel and rack engages, one end of described tooth bar is linked with hydraulic cylinder, and spring is arranged between the other end of tooth bar and cabinet wall.
Using above-mentioned further setting, Hydraulic Cylinder tooth bar moves, owing to rack and pinion engages, and gear concomitant rotation, thus band ovable valve stem rotates, and drives flap to rotate the most again and realizes opening of valve, now, spring-compressed；When closed, spring produces restoring force, promotes tooth bar to reset, and then band ovable valve stem, flap reset valve closing, and this kind of drive, simple in construction, transmission performance is reliable.
Further setting of the present utility model: described cabinet wall is provided with locating dowel, and tooth bar is arranged with banking stop, described spring one end is set in locating dowel and cabinet wall is conflicted, and the other end is set on tooth bar and banking stop is conflicted.
Use and above-mentioned further arrange, this spring set-up mode so that spring will not produce axially, radial position offset, good stability, and then ensure that the closedown of valve is relatively reliable.
The most further setting of the present utility model: described tooth bar is provided with annular spacing groove, and banking stop is fastened in stopper slot.
Use and above-mentioned the most further arrange, this banking stop set-up mode, simple in construction, install, dismantle convenient.
The most further setting of the present utility model: described casing includes the case lid of split setting, the first housing, the second housing, the 3rd housing, first shell one end is connected with case lid, the other end and the second housing connect, 3rd shell one end and the second housing connect, the other end is connected with hydraulic cylinder, hydraulic cylinder output shaft extends in the 3rd housing, spring is arranged in the first housing, tooth bar, gear are arranged in the second housing, tooth bar two ends extend respectively in the first housing, the 3rd housing, and described locating dowel is arranged on case lid.
Use and above-mentioned the most further arrange, this casing set-up mode, can facilitate and internal spring, tooth bar, gear are installed, dismantled；Furthermore, it is possible to the convenient processing to locating dowel.
