Abstract
The invention relates to a valve controller, in particular to a theft-proof valve controller capable of running stably. The valve controller comprises a box body and a box cover, wherein a worm gear is axially arranged in the box body and rotationally matched with a worm arranged at the upper part inside the box body, and a worm gear shaft hole is formed in the center of the worm gear. The valve controller is characterized in that a locking disk is fixedly connected onto the worm, locking disk holes are formed in the circumference of the locking disk, a locking lug is arranged at the upper part of the box body, a locking lug hole corresponding to the position of the locking disk holes is formed in the locking lug, the worm gear shaft hole is round, a stepped platform is arranged in the center of the worm gear shaft hole, and a cylindrical worm gear shaft matched with a worm gear shaft hole key groove is inserted in the stepped platform. The valve controller has excellent properties, is convenient to apply and is protected, damage caused by excessively large torsion to the worm gear and the worm is prevented, and the valve controller has a theft-proof function.
Description
Technical field
The present invention relates to a kind of valve positioner, particularly relate 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.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, provides a kind of function admirable, and 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 present invention 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 invention has the beneficial effects as follows:
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 invention.
Fig. 2 is perspective view of the present invention.
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 technological scheme of the present invention better, below in conjunction with accompanying drawing and most preferred embodiment, the present invention is described in further detail.
As shown in Figure 1, the present invention includes 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 the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
