Including the valve member, be equipped with the gear box on the valve body of valve member, in the valve rod in the valve member extended to the gear box, was connected with worm wheel and scale indicating dial in the valve rod upper end, worm wheel and the relative valve rod of scale indicating dial are fixed, and in the gear box was located to the worm wheel, be equipped with on the gear box and extend to the inside worm with worm wheel complex of gear box, but the worm gear box rotation relatively. The utility model discloses simple structure can show the angle of opening and shutting of valve plate in the valve outside to make the control that the valve flow can be accurate, adopt worm gear's drive mode simultaneously, make the angle of opening and shutting of valve plate finely tune, make the valve flow can further carry out accurate control.
Description
Technical Field
The utility model belongs to the valve field especially relates to an accurate valve of flow control.
Background
The angle difference of valve plate and valve body can't be directly observed from the outside to current valve to the valve plate upper end of traditional valve is direct through hand wheel drive valve rod, hardly holds accurate angle like this when adjusting valve plate and valve body angle, thereby unable accurate adjusting valve's flow.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is to the difficult accurate regulating valve flow of current valve and the accurate valve of a flow control that provides.
The utility model discloses a realize through following technical scheme:
the utility model provides an accurate valve of flow control, includes the valve component, is equipped with the gear box on the valve body of valve component, and in the valve rod in the valve component extended to the gear box, be connected with worm wheel and scale indicating dial on the valve rod, worm wheel and the relative valve rod of scale indicating dial are fixed, and in the gear box was located to the worm wheel, be equipped with on the gear box and extend to the inside worm with worm wheel complex of gear box, but the worm gear box relatively rotated.
The connecting part of the worm and the gear box is respectively provided with a first self-lubricating sleeve and a second self-lubricating sleeve.
A step is formed between the worm extending into the gear box and the outer part of the worm exposed out, the diameter of the worm extending into the gear box is smaller than that of the outer part of the worm exposed out, and a third self-lubricating sleeve is arranged at the step.
One end of the worm is connected with a hand wheel.
The hand wheel is fixed on the worm through a large pan head screw, and a plug is arranged on the hand wheel at the end part of the large pan head screw.
The scale indicating dial and the worm wheel are fixed on the valve rod through a large dial head screw, and the scale indicating dial at the end part of the large dial head screw is provided with a plug.
The utility model has the advantages that: the utility model discloses simple structure can show the angle of opening and shutting of valve plate in the valve outside to make the control that the valve flow can be accurate, adopt worm gear's drive mode simultaneously, make the angle of opening and shutting of valve plate finely tune, make the valve flow can further carry out accurate control.

FIG. 2 is a front view of the present invention with a partial cutaway;
fig. 3 is a top view of the present invention in partial section.
Detailed Description
The present invention will be further described with reference to the following examples.
Examples
As shown in fig. 1-3, a valve with accurate flow control comprises a valve component 14, a gear box 6 is arranged on a valve body of the valve component, a valve rod in the valve component extends into the gear box, a worm wheel 5 and a scale indicating disc 1 are connected to the upper end of the valve rod, the worm wheel and the scale indicating disc are fixed relative to the valve rod, the worm wheel is arranged in the gear box, a worm 12 which extends into the gear box and is matched with the worm wheel is arranged on the gear box, and the worm can rotate relative to the gear box. The connecting parts of the worm and the gear box are respectively provided with a first self-lubricating sleeve 9 and a second self-lubricating sleeve 10. A step is formed between the worm extending into the gear box and the outer part of the worm exposed out of the gear box, the diameter of the worm extending into the gear box is smaller than that of the outer part of the worm exposed out of the gear box, and a third self-lubricating sleeve 11 is arranged at the step. One end of the worm is connected with a hand wheel 13, and the other end of the worm extends to the outside of the gear box and is locked by a locking nut 8. The hand wheel is fixed on the worm through a large pan head screw 2, and a plug 3 is arranged on the hand wheel at the end part of the large pan head screw. The scale indicating dial and the worm wheel are fixed on the valve rod through a large dial head screw, and the scale indicating dial at the end part of the large dial head screw is provided with a plug. A first gasket 4 is arranged between the worm wheel and the scale indicating disc, and a second gasket 7 is arranged between the worm wheel and the gear box.
When manual rotation hand wheel, the hand wheel drives the worm and rotates, and the worm drives the worm wheel and rotates, and the worm is not only laborsaving when driving worm wheel pivoted to can make the worm wheel rotate slower, drive the valve rod when the worm wheel pivoted and rotate, because the worm produces the speed reduction when driving the worm wheel, thereby realize that the angle of opening and shutting of the valve plate (the butterfly plate) of valve rod lower extreme can finely tune, realize the accurate control of flow, can play fabulous effect in special trade.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that simple modifications and substitutions by those skilled in the art are within the scope of the present invention without departing from the spirit and scope of the present invention.
