Abstract
The invention discloses a limit switch for a valve actuator.The limit switch comprises a switch body, and a mechanical control part is arranged on the switch body in an inserted mode and can be manually separated from the switch body; the mechanical control part is provided with a control arm which is elastically connected with the mechanical control part, the tail end of the control arm is provided with a rolling wheel, the side face of the switch body is provided with a flaky magnet, and the surface of the magnet is of a shallow concave structure.According to the limit switch for the valve actuator, the switch body and the mechanical control part are designed to be two parts which are mutually independent, and the two parts can be conveniently connected with each other in an inserted mode; when the mechanical control part is damaged, only the mechanical part is replaced without disassembling the switch body and replacing the switch body with a new one, and time and labor are better saved while the sources are saved; meanwhile, the switch can be adsorbed at the needed place through the flaky magnet arranged on the switch body, screw connection is reduced, and disassembling and replacing are convenient.
Description
Technical field
The present invention relates to a kind of limit switch, more precisely, be a kind of limit switch for valve actuator.
Background technology
Limit switch is also known as travel switch, it is possible to be arranged on the object (such as fixed mount, doorframe etc., abbreviation still life) of geo-stationary or on the object (such as driving, door etc., abbreviation animal) of motion.When animal is close to still life, the connecting rod of switch drives the contact of switch to cause the contact disjunction of Guan Bi or the junction closure of disconnection.Control circuit and motor is removed by the change of make and break contact opening and closing state.For the prolonged and repeated activity of limit switch mechanical part of valve actuator, wear damage is more common, and the miscellaneous part switched then seldom damages, if directly change whole limit switch every time, easily causes the waste of resource.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus providing a kind of mechanical activity portion can separate the limit switch for valve actuator of replacing with Switch main body.
The above-mentioned technical problem of the present invention is addressed mainly by following technical proposals:
A kind of limit switch for valve actuator, comprise a Switch main body, it is provided with a Mechanical course portion with plugging with described Switch main body, described Mechanical course portion can from manual separation Switch main body, described Mechanical course portion is provided with a control arm, is elastic connection between described control arm and Mechanical course portion, and the end of described control arm is provided with a roller, being additionally provided with flap Magnet in the side of Switch main body, the surface of this Magnet is scrobicula structure.
As preferred embodiment of the present invention, connect for spring between described control arm and Mechanical course portion.
As preferred embodiment of the present invention, described roller is rubber roll.
Switch main body and Mechanical course portion are designed to separate two part by the limit switch for valve actuator of the present invention, can be mutually inserted easily between the two part, when Mechanical course portion only changes this mechanical part after damaging, Switch main body need not be changed, more time saving and energy saving while saving resource.Meanwhile, switch can be adsorbed on the place of needs by the flaky magnet that Switch main body is arranged, and decreases screw and connects, changes conveniently.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the limit switch for valve actuator of the present invention；
Fig. 2 is the perspective view of the limit switch for valve actuator in Fig. 1, is now another visual angle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining.
As shown in Figure 1 and Figure 2, a kind of limit switch 1 for valve actuator, comprise a Switch main body 2, a Mechanical course portion 3 it is provided with plugging with described Switch main body 2, described Mechanical course portion 3 can from manual separation Switch main body 2, described Mechanical course portion 3 is provided with a control arm 41, it is elastic connection between described control arm 41 and Mechanical course portion 3, the end of described control arm 41 is provided with a roller 42, being additionally provided with flap Magnet 5 in the side of Switch main body 2, the surface of this Magnet 5 is scrobicula structure.
As to further improvement of the present invention, connecting for spring between described control arm 41 and Mechanical course portion 3.
As to further improvement of the present invention, described roller 42 is rubber roll.
Switch main body and Mechanical course portion are designed to separate two part by the limit switch for valve actuator of this invention, can be mutually inserted easily between the two part, when Mechanical course portion only changes this mechanical part after damaging, Switch main body need not be changed, more time saving and energy saving while saving resource.Meanwhile, switch can be adsorbed on the place of needs by the flaky magnet that Switch main body is arranged, and decreases screw and connects, changes conveniently.
The mentality of designing of the present invention is below only described in one embodiment, and when system allows, the present invention can expand to external more functional module simultaneously, thus extending its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention be not limited thereto, any change expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with claims protection defined.
