Abstract
The utility model relates to a rack type part rotary valve hydraulic transmission device which comprises a hydraulic piston cylinder device and a valve openness indicating and controlling device, wherein the hydraulic piston cylinder device consists of a cylinder body, a cylinder cover, a piston and a piston rod; mainly, the piston rod is connected with a rack which is meshed with a gear; and the gear is fixed on the end part of a valve shaft. The piston rod directly transmits the rack and the gear opens and closes the valve, so that the hydraulic transmission device has the advantages of compact structure, small product installation space, strong adaptability to installation conditions, and the like, and is applicable to the part rotary valve hydraulic transmission devices such as a butterfly valve, a ball valve, a butterfly type check valve and the like.
Description
Technical field
The utility model relates to a kind of hydraulic transmission, particularly relates to the supporting hydraulic transmissions of part turning valve such as a kind of and butterfly valve, ball valve, butterfly check valve.
Background technique
That the driving mode of part turning valves such as butterfly valve, ball valve, butterfly check valve mainly contains is manual, electronic, pneumatic, surge etc.Common hydraulic transmission mainly adopts the kinds of drive such as oscillating oil cylinder linkage type, fixed oil cylinder fork.Wherein the transmission of oscillating oil cylinder linkage type takes up room greatly, is used for seeming that structure is too fat to move, loose when smaller diameter valve is supporting; The transmission of fixed oil cylinder fork is not because the narrow limitation of its structure is suitable for the supporting of heavy load; And in a single day the valve of these two kinds of matched with devices dispatches from the factory, and the installation position of final controlling element is also promptly fixing, can not adjust bad adaptability according to the fitting operation environment at scene again.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, a kind of compact structure is provided, occupies little space, install adaptable rack-type part turning valve hydraulic transmission.
The technical solution of the utility model comprises hydraulic piston cylinder assembly, valve opening indication and control gear, described hydraulic piston cylinder assembly comprises cylinder body, cylinder cap, piston, piston rod, mainly be that piston rod connects a tooth bar, this tooth bar and a gear are meshing with each other, and gear is fixed on the valve shaft end.
In above technological scheme, tooth bar one side is provided with rack and wheel matching gap controlling device, and this rack and wheel matching gap controlling device is made up of guide pad and regulating block, guide pad and tooth bar one side contacts, be threaded with regulating block, regulating block is installed on the casing by screw.
In above technological scheme, cylinder cap is provided with slow closing device, and described slow closing device is made up of the Slow Close piece, the Slow Close stroke regulating lever that insert the cylinder cap center hole, and described Slow Close stroke regulating lever is fixedly mounted on the piston end surface center by socket head screw.
The beneficial effects of the utility model are the direct driving racks of piston rod, the transmitting gear opening/shutting valve, have compact structure, product installing space little, to advantages such as adaptability for working condition is strong are installed.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Rack-type part turning valve hydraulic transmission as shown in Figure 1 comprises hydraulic piston cylinder assembly, valve opening indication and control gear, rack gearing.Described hydraulic piston cylinder assembly comprises cylinder body 9, cylinder cap 11, piston 10, piston rod 8.Described rack gearing is made up of pitch wheel 2 and tooth bar 7, and tooth bar 7 is threaded with piston rod 8, and gear 2 is fixed on the valve shaft end.The end of piston rod 8 is provided with set screw nut 3, and is by regulating the position of tooth bar 7 on piston rod 8, that the stroke adjustment of piston 10 is extremely corresponding with 90 ° of strokes of gear rotation.
Side at tooth bar 7 is provided with rack and wheel matching gap controlling device, this rack and wheel matching gap controlling device is made up of guide pad 6 and regulating block 4, guide pad 6 is threaded with regulating block 4, and it is fixing by set screw 5, one side contacts of the guide surface of guide pad 6 and tooth bar 7, regulating block 4 is installed on the casing 1 by screw.By regulating the screw-thread fit position of guide pad 6 in regulating block 4, can adjust the matching gap of tooth bar 7 and gear 2, make its symbol transmission requirement.
