Description
Technical field
The present invention relates to a kind of parts of valve, especially relate to a kind of hidden rod sluice valve switch indicator.
Background technique
The Stem Mut of inside screw non-rising stem type gate valve is located on flashboard, and hand wheel rotating band ovable valve stem rotates, and comes the lifting flashboard, thus the opening and closing valve.Due to the lift-bolt of inside screw non-rising stem type gate valve in the gate valve cavity, so can't directly observe the on off state of valve outside cavity.When operation, usually by calculating the rotation number of turns of handwheel, the opening state of judgement valve.The aperture value that seals when flashboard is K, and when valve rod pitch value was P, the number of total coils of valve opening was the N=K/P circle, and the general normal number of turns is 10 ~ 26 circles.In practical operation, usually because the people is misoperation, causes the valve opening deficiency or do not close fully, affected normal use.Therefore, an indicator that can accurately show the valve switch state need to be set on inside screw non-rising stem type gate valve.
Chinese patent CN10344186B discloses a kind of hidden rod sluice valve switch indicator, it comprises that the outside has the step-like hollow chassis of level Four, graduated ring, driving pin, eccentric driver plate, cycloid wheel and pinwheel, drive eccentric driver plate by hand wheel rotating and rotate, eccentric driver plate band plane gear is round cycloid crop rotation revolution and rotation.Driving pin rotates with pinwheel, and the rotation of pinwheel is passed to graduated ring, obtains groove and handwheel rotating in same direction on dial, thereby shows the valve switch state.Although the disclosed a kind of hidden rod sluice valve switch indicator of this patent can show the on off state of inside screw non-rising stem type gate valve, the drive mechanism of the multi-stage stairs shape that its adopts is too complicated, easily damages, and fabricating cost is higher, and loading and unloading and maintenance all very inconvenient.
Summary of the invention
In order to overcome the defective of prior art, the purpose of this invention is to provide a kind of simple in structure, use more reliable, fabricating cost is lower, load and unload and keep in repair convenient hidden rod sluice valve switch indicator.
in order to achieve the above object, the invention provides a kind of hidden rod sluice valve switch indicator, it is characterized in that: it comprises hollow base, internal gear, planetary pinion, fixing pin, turning wheel and cover plate, wherein said internal gear is located in described hollow base rotationally, described planetary pinion is fixed on described hollow base by described fixing pin and can be along self axial rotation, described internal gear and the engagement of described planetary pinion, described turning wheel is located in described hollow base rotationally, described turning wheel and the engagement of described planetary pinion, described cover plate covers on described hollow base, on described cover plate, the upper-end surface of corresponding described internal gear is provided with viewing window.
Preferably, described viewing window is provided with graduation line.
Preferably, also be provided with spring and steel ball in described planetary pinion, described steel ball is being pushed against on described hollow base under the pressure-acting of spring.Adopt such structure, make the planetary pinion more stable work, avoid planetary pinion to produce easily rotation when the cingulum that is not subject to turning wheel is moving.
Preferably, the axle center of the axle center of described internal gear, described planetary axle center and described turning wheel is located along the same line.More preferably, described internal gear and described turning wheel arrange with one heart.
Preferably, the described planetary number of teeth is 7 teeth, and the number of teeth of described turning wheel is 1 ~ 3 tooth.
Working principle of the present invention is: drive described turning wheel rotation when hand wheel rotating, turning wheel drives described planetary pinion rotation, planetary pinion drives again the internal gear rotation, realized larger velocity ratio, the stroke of internal gear rotation can show the on off state of inside screw non-rising stem type gate valve, and operator just can check on off state easily from the viewing window of cover plate.
Compared to prior art, hidden rod sluice valve switch indicator provided by the invention, structure is simpler, and reliability is higher, and fabricating cost is lower, and loading and unloading and maintenance are all convenient.
