Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Refer to accompanying drawing 1, a kind of butterfly valve, including valve body 1, dish plate 2, valve rod 3, valve body 1 has a through hole 11, dish plate
2 are arranged at the through hole 11 of valve body 1, and are connected with valve rod 3, are provided with one handle 4, and one in the upper end of valve rod 3
Drive motor 5, circumferentially rotate for axle center it is thus possible to realize the center that two ways produces with valve rod 3 to make the dish plate 2 of valve rod 3,
Thus realize being turned on or off valve body 1.
Refer to accompanying drawing 2, the outer circumference surface of dish plate 2 is provided with three magnetic parts 21, the centre of three magnetic parts 21
Magnetic part 21 is provided at the circular same level height of dish plate 2, and three magnetic parts 21 less than dish plate 2 excircle
The height on surface, such that it is able to keep the sealing property of dish plate 2.
Refer to accompanying drawing 2, the first magnetic that the inwall of the through hole 11 of valve body 1 is provided with at the closed position of dish plate 2
Switches set 12, the first magnetic switch group 12 is three longitudinally disposed magnetic switch, the central magnetic switch of three magnetic switch
Being also disposed at the middle position of valve body 1, the height of three magnetic switch is less than the height of the inside of through hole 11, it is thus possible to protect
The sealing of card valve body 1.Three magnetic switch are Hall element, after sensing the magnetic field of corresponding magnetic part 21, just
Can send corresponding signal, and three magnetic switch are all welded on the pcb board of one piece of arc, the radian of pcb board and valve body 1
Corresponding radian is suitable.It is provided with pcb board and can aid in the installation and removal of whole Hall element, and it is succinct to arrange,
Simultaneously facilitating maintenance, pcb board is suitable with the arc of valve body 1 it is thus possible to play Hall element and more fit valve body 1, makes and magnetic
Property part 21 contact more tight, detection efficiency is high.
Refer to accompanying drawing 2, be placed with the second magnetic switch group 13 in the both sides of the first magnetic switch group 12, wherein each
Side is all placed with two magnetic switch, and height is identical with the central magnetic switch height and position of the first magnetic switch group 12, thus
If dish plate 2 can be played not to be had in correct closed position, direction and the side-play amount of skew can be detected, thus convenient
Operator goes maintenance, so that butterfly valve closes completely, it is ensured that the safety of production.
And drive motor 5 outer surface be provided with a luminescent device 51, luminescent device 51 can be electric filament lamp or
LED etc., luminescent device 51 is connected with a power supply, and luminescent device 51 saves with three magnetics phase couplings, serves at magnetic
Property element senses is to after the field signal of magnetic part 21, and luminescent device 51 sends light, thus allow make employment learn dish plate 2 is in
Correct make position.
Its operation principle is: when dish plate 2 is shelved on correct through hole 11 inside, the excircle of dish plate 2 has Magnet,
Having magnetic, Magnet is when the first magnetic switch group 12 (Hall element), thus triggers Hall element output sensing
Signal makes the luminescent device 51 of correspondence light, such that it is able to the information that indicating closing position is correct, and it is provided with three magnetic
Property switch and three magnetic parts 21, three signals can be exported, add the accuracy of output, when three signals all export make send out
When optical device 51 is luminous, i.e. can confirm that dish plate 2 in correct make position, when only one of which signal or two signals outputs
When making luminescent device 51 luminous, it is necessary to make employment go to detect whether dish plate 2 has the sideslip on position.And ought the only second magnetic
The corresponding luminescent device 51 of switches set 13 is lighted and is made, by the luminescent device 51 lighted, operator just can determine that dish plate 2 is inclined
The direction moved and substantially side-play amount, embody the margin of error and direction it is thus possible to play, more intuitively for making the maintenance of employment
Provide conveniently.
Embodiment 2:
Refer to accompanying drawing 3, on the basis of embodiment 1, the inwall at valve body 1 through hole 11 is provided with sealing ring 6, and
The first magnetic switch and the second magnetic switch switch size hole identical with quantity it is provided with at the magnetic switch of sealing ring 6,
It is achieved thereby that magnetic switch will not be stopped, it is to avoid affect the magnetic field detection of magnetic switch, and the difference from embodiment 1
Be, the height of the first magnetic switch group 12 and the second magnetic switch group 13 have only to less than sealing ring 6 inwall height i.e.
Can, preferentially select identical with the height of sealing ring 6 inwall in the middle of the present embodiment.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
