Description
Technical field
The utility model relates to a kind of valve positioner, particularly relates to a kind of stable anti-theft valve positioner.
Background technique
At present, valve positioner is applied widely in industrial production and engineering construction, plays very important effect.But adopt existing valve positioner to control the output of gas, wet goods resource, the worm screw arbitrarily can opening valve positioner exports, and often there is the hidden danger of the easy stolen mistake of resource, thus can cause great economic loss and security incident; In order to avoid above-mentioned situation occurs, usually need configuration lock or combination lock to protect aborning, production and user cost can be strengthened so again, operational inconvenience can be brought simultaneously, and existing a kind of stable valve positioner, this valve positioner comprises casing, case lid; Worm gear is axially arranged with in described casing, the worm screw be provided with casing internal upper part is rotatably assorted, described worm gear center is provided with worm gear axis hole, wherein worm gear axis hole is square hole, and worm-wheel shaft front end is also set to coordinate with square hole square, and when controlling torsion and being excessive, worm-wheel shaft drives the Power output of worm gear and worm screw, worm gear and worm screw are damaged, and valve positioner runs and is destroyed.
Model utility content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art; a kind of function admirable is provided; application is convenient, and Protective valve door controller, prevents worm gear and worm screw from the stable anti-theft valve positioner destroyed occurring because torsion is excessive.
The utility model is achieved by the following technical programs:
A stable anti-theft valve positioner, this valve positioner comprises casing, case lid; Worm gear is axially arranged with in described casing, the worm screw be provided with casing internal upper part is rotatably assorted, described worm gear center is provided with worm gear axis hole, described worm screw is connected with lock collar, and described lock collar ring week is provided with lock collar hole, and the top of described casing is provided with lock ear, described lock ear is provided with the lock earhole corresponding with lock collar hole site, described worm gear axis hole is circular, and is provided with ladder platform in worm gear axis hole central position, described ladder platform is inserted with the cylinder worm-wheel shaft coordinated with worm gear axis hole keyway.
The beneficial effects of the utility model are:
Due to described worm screw being connected with lock collar, described lock collar ring week is provided with lock collar hole, the top of described casing is provided with lock ear, described lock ear is provided with the lock earhole corresponding with lock collar hole site, is locked in lock collar hole and lock both earholes, effectively prevent worm screw relative to the rotary motion of casing with lock, play antitheft effect, function admirable, application is convenient, safe and reliable.Because described worm gear axis hole is circular; and be provided with ladder platform in worm gear axis hole central position; described ladder platform is inserted with the cylinder worm-wheel shaft coordinated with worm gear axis hole keyway; when torsion exports excessive; the key be located in worm gear axis hole and worm-wheel shaft keyway is first destroyed; thus protect valve positioner, prevent worm gear and worm screw from destroying because torsion is excessive, make it stable.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model.
Fig. 2 is perspective view of the present utility model.
In figure: 1. casing, 2. worm gear, 3. worm screw, 4. keyway, 5. worm gear axis hole, 6. lock collar, 7. locks ear, 8. lock collar hole, 9. locks earhole, 10. worm-wheel shaft, 11. case lids, 12. ladder platforms.
Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises casing 1, case lid 11; Worm gear 2 is axially arranged with in described casing, the worm screw 3 be provided with casing internal upper part is rotatably assorted, described worm gear center is provided with worm gear axis hole 5, described worm screw is connected with lock collar 6, described lock collar ring week is provided with lock collar hole 8, and the top of described casing is provided with lock ear 7, described lock ear is provided with the lock earhole 9 corresponding with lock collar hole site, described worm gear axis hole is circular, and is provided with ladder platform 12 in worm gear axis hole central position, described ladder platform is inserted with the cylinder worm-wheel shaft 10 coordinated with worm gear axis hole keyway.This spacing worm-wheel shaft position of routine scala media halfpace, makes it move more steady.
Because described worm gear axis hole is circular; and be provided with ladder platform in worm gear axis hole central position; described ladder platform is inserted with the cylinder worm-wheel shaft coordinated with worm gear axis hole keyway; when torsion exports excessive; the key be located in worm gear axis hole keyway 4 and in worm-wheel shaft keyway is first destroyed; thus protect valve positioner, prevent worm gear and worm screw from destroying because torsion is excessive, make it stable.
Due to described worm screw being connected with lock collar, described lock collar ring week is provided with lock collar hole, the top of described casing is provided with lock ear, described lock ear is provided with the lock earhole corresponding with lock collar hole site, is locked in lock collar hole and lock both earholes, effectively prevent worm screw relative to the rotary motion of casing with lock, play antitheft effect, function admirable, application is convenient, safe and reliable.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
