Description
Technical field
The present invention relates to valve matched device field, more particularly to a kind of many turning valves of visual stem position are manual Drive device.
Background technology
With the continuous expansion of valve applications scope, in some requirement controls more accurately operating mode, such as choke valve, its It need not often be adjusted, be such as controlled using YE, cost is high.In this case, it is general only to need It is operated manually using manual driving device, but existing manual driving device accurately can not be intuitively recognized residing for valve Station, therefore can cause control it is not accurate.
The content of the invention
, can the present invention solves the technical problem of a kind of many turning valve manual driving devices of visual stem position are provided Solving existing drive device intuitively can not accurately observe the defect of station residing for valve.
In order to solve the above technical problems, one aspect of the present invention is：A kind of visual stem position is provided Many turning valve manual driving devices, including：Drive device housing and installed in the transparent anti-of the drive device housing upper end Bevel pinion, bevel gear wheel, valve stem nut and valve rod, the auger tooth are installed in dust hood, the drive device housing Wheel intermeshes with the bevel pinion, and the valve stem nut is arranged in the bevel gear wheel and passed through with the bevel gear wheel Bushing connection, the valve rod is screwed in the valve stem nut, and one end connecting valve of the valve rod, the other end can Stretch out the drive device housing and stretch in the transparent dust cover.
In a preferred embodiment of the present invention, the transparent dust cover is cylindrical, including lower end connection end, upper end are prevented Protecting cover and the transparent vitreous body between the lower end connection end and upper end protective cover.
In a preferred embodiment of the present invention, valve location scale sign is provided with the transparent vitreous body.
In a preferred embodiment of the present invention, the bottom of the lower end connection end is provided with external thread structure, described outer Helicitic texture is screwed in drive device housing.
In a preferred embodiment of the present invention, the junction of the external thread structure and drive device housing is provided with O Shape rubber seal.
In a preferred embodiment of the present invention, the lower end connection end and upper end protective cover are made of using PVC plastic 's.
The beneficial effects of the invention are as follows：The present invention is simple and reasonable, by installing transparent in drive device housing upper end Dust cover, can intuitively observe the position of valve rod, and then be easy to accurately understand station residing for valve；Simultaneously in valve rod Dust cover is installed in upper end, can improve the dustproof and waterproof performance of drive device, improve its service life.

Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Fig. 1 and Fig. 2 are referred to, the embodiment of the present invention includes：
A kind of many turning valve manual driving devices of visual stem position, including：Drive device housing 1 and installed in it is described drive Bevel pinion 3, bevel gear wheel 4, valve are installed in the transparent dust cover 2 of the dynamic upper end of device case 1, the drive device housing 1 Stem nut 5 and valve rod 6, the bevel gear wheel 4 intermesh with the bevel pinion 3, and the valve stem nut 5 is arranged on institute State in bevel gear wheel 4 and be connected with the bevel gear wheel 4 by bushing 7, the valve rod 6 is screwed in the valve stem nut 5 Interior, the extended drive device housing 1 of one end connecting valve of the valve rod 6, the other end is simultaneously stretched to described transparent In dust cover 2, valve location scale sign 231 is marked with the middle part transparent vitreous body 23 of the transparent dust cover 2, passes through institute The position of valve rod 6 can intuitively be observed by stating transparent vitreous body 23, and station residing for valve is understood so as to accurate.
Wherein, the transparent dust cover 2 is cylindrical, including lower end connection end 21, upper end protective cover 22 and positioned at described Transparent vitreous body 23 between lower end connection end 21 and upper end protective cover 22, it is preferable that the lower end connection end 21 and upper end are prevented Protecting cover 22 is made of PVC plastic.
Also, the bottom of the lower end connection end 21 has been integrally machined external thread structure, the external thread structure screw in In drive device housing 1；The junction of the external thread structure and drive device housing 1 is provided with O shapes rubber seal 8, can The sealing of the transparent dust cover 2 and the junction of drive device housing 1 is improved, and then improves the protective of the drive device Energy.
It is simple and reasonable present invention is disclosed a kind of many turning valve manual driving devices of visual stem position, lead to Cross and transparent dust cover is installed in drive device housing upper end, can intuitively observe the position of valve rod, and then be easy to accurate understanding Station residing for valve；Dust cover is installed in the upper end of valve rod simultaneously, the dustproof and waterproof performance of drive device can be improved, is improved Its service life.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills Art field, is included within the scope of the present invention.
