Description
Technical Field
The utility model relates to an intelligence water gauge technical field, in particular to intelligence water gauge control box valve rod shaft hole seal structure.
Background
The prepayment water meter actuating device on the market is controlled by a motor speed reducing mechanism of a control box, the control box is communicated with the outside, and therefore the sealing performance of the control box is particularly important.
Most of the existing control boxes and water meter base meters are directly connected through threads, valve rods are inserted into control box holes, valve rod sealing rings and hole walls realize dynamic sealing, the sealing structure has requirements on assembly, eccentricity is easily generated, so that the sealing performance is poor, long-time working abrasion is large, and the service life is short.
Disclosure of Invention
The utility model discloses a remedy prior art not enough, provide an intelligence water gauge control box valve rod shaft hole seal structure.
The utility model discloses a realize through following technical scheme:
the utility model provides an intelligence water gauge control box valve rod shaft hole seal structure, includes the watchcase, the top of watchcase is equipped with integrated into one piece's engaging lug, the top and the connecting plate threaded connection of engaging lug, connecting plate and control box threaded connection, install the sealing washer between connecting plate and the control box.
The connecting plate is step-shaped, and the sealing washer cover is in the step position of connecting plate.
The steel ball is installed in the shell and connected with a motor speed reducing mechanism installed in the control box through a valve rod.
One end of the meter shell is connected with the valve plug through threads.
And ball seals and valve plug sealing rings are sequentially arranged among the steel balls, the meter shell and the valve plug.
The valve rod is connected with the connecting lug in a dynamic sealing manner.
The utility model discloses following beneficial technological effect has:
this novel connection plate structure and control box that adopts exist quiet sealedly, and sealing performance does not receive assembly or screw hole quality influence basically, and the leakproofness is more stable, and the life-span is longer, makes the waterproof performance of control box obtain further optimization.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-meter shell, 2-valve plug, 3-ball seal, 4-valve plug seal ring, 5-steel ball, 6-valve rod, 7-valve rod seal ring, 8-connecting plate, 9-seal ring, 10-motor reducer and 11-control box.
Detailed Description
The following are only embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
In the present invention, the words describing the directional relationship such as "left", "right", "inner", "outer" are only convenient for describing the embodiment, and are not considered to be limitations of the present invention. The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The fixed connection mode comprises but is not limited to a connection mode known in the prior art, such as welding, screwing, clamping, interference fit, integral forming and the like; the number of the plurality is more than one.
Fig. 1 shows an embodiment of the present invention. This embodiment provides an intelligence water gauge control box valve rod shaft hole seal structure, watchcase 1 including one end and valve plug 2 threaded connection, install steel ball 5 in watchcase 1, all install ball 3 between this steel ball 5 and watchcase 1 and between steel ball 5 and valve plug 2, all install valve plug sealing washer 4 between ball 3 and watchcase 1 and between ball 3 and valve plug 2, it is specific to install ball 3 and valve plug sealing washer 4 between steel ball 5 and the watchcase 1 in proper order as shown in figure 1, install ball 3 and valve plug sealing washer 4 between steel ball 5 and the valve plug 2 in proper order, and ball 3 is located between valve plug sealing washer 4 and the steel ball 5. The steel ball 5 is connected with a motor reducing mechanism 10 fixedly arranged in a control box 11 at the top of the watchcase 1 through a valve rod 6, and a valve rod sealing ring 7 is arranged between the valve rod 6 and the watchcase 1. Specifically, the top of the wristwatch case 1 is provided with a lug formed integrally with the wristwatch case 1, and the top of the lug is engaged with the internal thread of the connecting plate 8 by an external thread. The connecting plate 8 is step-shaped, a through hole matched with the connecting lug is arranged in the middle of the connecting plate, the connecting plate 8 is in threaded engagement with the control box 11 through external threads, and the valve rod 6 sequentially penetrates through the connecting lug and the connecting plate 8 to enter the control box 11 to be fixedly connected with the output end of the motor reducing mechanism 10; valve rod sealing rings are arranged between the valve rod 6 and the connecting lugs and between the valve rod and the connecting plate 8 to form dynamic sealing connection. A sealing ring 9 is further installed between the connecting plate 8 and the control box 11, and the sealing ring 9 is sleeved at the step position of the connecting plate 8.
Install connecting plate 8 and sealing washer 9 additional between watchcase 1 and control box 11, valve rod 6 passes and enters into control box 11 behind this connecting plate 8, forms static seal between connecting plate 8 and the control box 11, and sealing performance does not basically receive assembly or screw hole quality influence, and the leakproofness is more stable, and the life-span is longer, makes the waterproof performance of control box obtain further optimization.
