Cylinder 13, the switch outer barrel 13 are fixedly installed in the upper surface of gland 8, are fixedly mounted in the middle part of the madial wall of the switch outer barrel 13
There are light sensor 14, the upper surface right end of the handwheel 10 to be installed with electronic counter 15, the switch outer barrel 13
Lateral wall left end bottom is installed with display shell 16, and link block is installed in the middle part of the front side wall of the movement nut 12
The other end of 17 one end, the link block 17 is installed with rack 18, and the front side wall of the rack 18 is engaged with gear 19,
The left side wall of the gear 19 is plugged with leading screw 20, and the left end of leading screw 20 is plugged in the inner cavity of display shell 16, the leading screw
20 lateral wall is bolted with mobile item 21, and the rear and front end of the mobile item 21 is connected with card slot 26, and two card slots 26 divide
It is not opened in the front-rear side walls of display shell 16, the upper surface of the display shell 16 offers transparent panel 22, the transparent panel
22 upper surface left and right ends offer limit graduation mark 23, the electronic counter 15 be electrically connected external power supply, first when
Rotation hand wheel 10 when inside screw nonrising stem type gate valve is opened, handwheel 10 are rotated with ovable valve stem 5 in turn, and valve rod 5 rotates and then flashboard 3 is driven to be carried
It rises, recirculation hole 2 is opened, while movement nut 12 moves upwards, and at this moment nut 12 can block light sensor 14, and light passes
Sensor 14 will receive signal and signal is passed to electronic counter 15, and electronic counter 15 will record movement nut
The number of 12 movements, since the initial position of movement nut 12 is in bottom, so when the quantity of electronic counter 15 is odd number
It is that flashboard 3 moves upwards, the state that inside screw nonrising stem type gate valve is opened is that flashboard 3 closes when the display number of electronic counter 15 is even number
The state closed, while what electronic counter 15 can be clear knows valve rod 5 has worked how many, and can periodically be added for it
Lubricating oil, along with the display shell 16 of switch 13 left end of outer barrel can allow people to be directly viewable switch in the case of vertical view
State will not be moved upwards when movement nut 12 moves upwards and then because excessive operation is to damage gate valve with carry-over bar 18,
Rack 18 is rotated forward with moving gear 19 in turn, and gear 19 rotates forward and then drive the rotation of leading screw 20, leading screw 20 to rotate and then drive movement
Item 21 rotates, at this moment mobile item 21 moves item 21 and just moved downward due to being connected in card slot 23 and then cannot rotate, if
When mobile item 21 moves to limit graduation mark 23, at this moment just prompt people cannot have rotated, and may only rotate backward, dark when closing
Lever brake threshold switch principle is identical, and movement nut 12 moves downward, and then mobile item 21 is driven to return to initial position, and then prompter
Cannot be rotated further, can only be rotated to negative direction, such operating personnel are readily seen the working condition of gate valve, be open also
It is to close, the degree of the opening for finding out gate valve or closing that can be simple and clear by mobile item 23, while ensuring gate valve
The functionality of long-time service.
Specifically, in order to facilitate rotation hand wheel 10, the madial wall of the handwheel 10 is equidistant to be evenly distributed with branch
Bar 24, and the range of tilt angles of strut 24 and handwheel 10 is at 0 degree to 10 degree.
Specifically, to improve the sealing effect of valve body 1, the upper surface left and right ends of the valve body 1 are installed with close
Seal 25.
Specifically, preventing one of light sensor 14 from breaking down influences to judge, the light sensor 14 shares two
It is a.
Operation principle：The rotation hand wheel 10 when inside screw nonrising stem type gate valve is opened first, handwheel 10 are rotated with ovable valve stem 5 in turn, valve rod 5
It rotates and then flashboard 3 is driven to be raised, recirculation hole 2 is opened, while movement nut 12 moves upwards, and at this moment nut 12 can be by light
Line sensor 14 blocks, and light sensor 14 will receive signal and signal is passed to electronic counter 15, electrometer
Number device 15 will record the number of the movement of movement nut 12, since the initial position of movement nut 12 is in bottom, so working as electronics
The quantity of counter 15 is that flashboard 3 moves upwards when being odd number, the state that inside screw nonrising stem type gate valve is opened, when showing for electronic counter 15
Registration is the state that flashboard 3 is closed when being even number, while electronic counter 15 can be clear that know that valve rod 5 has worked more
It is few, and can be periodically that it adds lubricating oil, along with the display shell 16 of switch 13 left end of outer barrel can allow people to overlook
In the case of be directly viewable the state of switch, will not be because excessive operation be to damage gate valve, when movement nut 12 moves upwards
And then moved upwards with carry-over bar 18, rack 18 is rotated forward with moving gear 19 in turn, and gear 19 rotates forward and then drive the rotation of leading screw 20,
Leading screw 20 rotates and then mobile item 21 is driven to rotate, at this moment mobile item 21 is moved due to being connected in card slot 23 and then cannot rotate
Item 21 is just moved downward, if mobile item 21 moves to limit graduation mark 23, at this moment just prompt people cannot have rotated, only
Rotation is can be reversed, when closing hidden rod sluice valve switch principle is identical, movement nut 12 moves downward, and then mobile item 21 is driven to return
It to initial position, and then prompts people that cannot be rotated further, can only be rotated to negative direction, such operating personnel are readily seen lock
The working condition of valve is to open or close, by mobile item 23 can be simple and clear the opening for finding out gate valve or closing
Degree, while ensuring the functionality of the long-time service of gate valve.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
