The height of the frangible grill 72 is greater than the vertical height between the level of the top end of the limit sleeve 7 and the level of the bottom end of the locking piston 4.
The implementation working process of the invention is as follows:
As shown in fig. 8, when the mechanical quantitative pre-selling water meter is used for adjusting the pre-selling water quantity according to the specific embodiment of the invention, the key hole at the lower part of the cylindrical center shaft of the key body 1 is aligned with the quantitative mechanism adjusting rod in the pre-selling water quantity adjusting hole on the upper surface of the water meter shell, meanwhile, two anti-reversion limiting blocks 13 are symmetrically arranged in the middle of the outer wall of the cylindrical center shaft of the key body 1 and aligned with two limiting notches at the edge of the pre-selling water quantity adjusting hole, and then the key body 1 is pressed downwards to be forcibly inserted.
When the upper end of the adjusting rod of the metering mechanism enters the vertical hollow through hole 14 of the key body 1 and contacts with the head 62 of the stop piston 6, the stop piston 6 is jacked up, and the tail piston rod 61 of the stop piston 6 passes through the fragile grille 72 at the tail guide hole 72 of the limiting sleeve 7 contacted with the tail piston rod 61. In addition, the side surface of the top of the limit sleeve 7 is in contact connection with the end surface of the locking piston 4 in the initial condition, the locking piston 4 does not block the upper end surface of the limit sleeve 7, the limit sleeve 7 can be pushed upwards by the locking piston 6, the main spring 8 is compressed, and finally the upper end surface of the limit sleeve 7 is pushed upwards to be in contact with the lower end surface of the main plug 9.
Then, further pressing force is applied to the key body 1, the continuously increased force continuously acts until the fragile grating 72 at the tail end of the tail guide hole 72 of the limit sleeve 7 is jacked by the tail piston rod 61 at the top end of the stop piston 6, so that the stop piston 6 breaks through the obstruction that the water meter can continue to ascend, the quantitative mechanism adjusting rod in the pre-selling water quantity adjusting hole in the water meter enters more vertical hollow through holes 14 of the key body 1, the key body also continues to descend until the middle anti-reversion limiting block 13 at the middle part of the middle shaft outer wall of the cylinder of the key body 1 is contacted with the bottom of the limit notch of the pre-selling water quantity adjusting hole in the water meter shell, and the spline at the end part of the quantitative mechanism adjusting rod is completely meshed with the inner tooth 51 of the quantitative adjusting gear ring 5, so that the key entering operation is completed.
Then, the key body 1 is rotated clockwise, the middle anti-reversion limiting block 13 at the outer wall of the middle shaft of the cylindrical middle shaft of the key body 1 is turned into an arc-shaped inner groove beside a limiting notch of a pre-selling water quantity adjusting hole on the water meter shell, and the key body 1 cannot be pulled out again in the axial direction, so that water selling failure is prevented.
In the process of rotating the key body 1 clockwise, the quantitative adjusting gear ring 5 drives the quantitative mechanism adjusting rod to rotate, and the pre-selling water quantity adjusting operation is implemented on the water meter. The rotation of the quantitative mechanism adjusting rod in the water selling meter is equivalent to the tightening of a spring, the quantitative mechanism adjusting rod can reversely generate torque to the quantitative adjusting gear ring 5, and the torque is transmitted to the four quantitative teeth 15 through the matching relation of the quantitative teeth 15 and the positioning grooves 52.
Because the water meter quantifying mechanism is tightened when the water meter quantifying mechanism regulates and increases the pre-selling amount of water, the torque required to be applied is also increased continuously, the torque is transmitted to the given amount regulating gear ring 5 through the spline of the regulating rod end of the quantifying mechanism, and the torque is further transmitted to four quantifying teeth 15 symmetrically arranged on the bottom side wall surface inside the cylindrical center shaft of the key body 1.
When the torque transmitted to the quantifying tooth 15 reaches the preset torsional strength limit value of the quantifying tooth 15, the quantity of water to be regulated and increased of the water meter quantifying mechanism also reaches the preset water quantity value, at this time, the quantifying tooth 15 is broken off from the root of the hole wall of the stepped hole of the vertical hollow through hole 14, the quantifying adjusting gear ring 5 and the key body 1 slide mutually due to the loss of the limit of the quantifying tooth 15, the rotating force acting on the key body 1 can not be transmitted to the quantifying mechanism adjusting rod through the quantifying adjusting gear ring 5 any more, and the preset water quantity of the water meter quantifying mechanism will not change any more.
Finally, the key body 1 continues to rotate clockwise under the force application until the anti-reversion limiting block 13 of the cylindrical center shaft of the key body 1 enters from the limiting notch at one side and then rotates 180 degrees, and then the anti-reversion limiting block passes through the arc-shaped inner groove of the pre-water selling quantity adjusting hole wall on the water meter shell and then rotates to the limiting notch at the opposite side of the 180-degree reverse direction of the pre-water selling quantity adjusting hole, and at the moment, the key body 1 is pulled out to finish the water selling process.
After the key body 1 is pulled out, the head 62 of the stop piston 6 is not pushed by the adjusting rod of the quantitative mechanism, and the stop piston 6 does not have upward pushing force on the limit sleeve 7, so that the stop piston 6 and the main spring 8 are simultaneously pushed to move downwards until the stop piston 6 contacts with the quantitative adjusting gear ring 5 and then stops. At this time, the stop sleeve 7 descends, and the fragile grille 72 is twisted, and the tail piston rod 61 of the stop piston 6 penetrates into the stop sleeve 7 more than in the initial situation, the downward stop position of the stop sleeve 7 is lower than the initial position when leaving the factory, and the locking piston 4 originally propped against the side wall of the stop sleeve 7 slides into the clearance between the stop sleeve 7 and the main plug 9 under the pushing of the auxiliary spring 3, so that the ascending position of the stop sleeve 7 is locked and limited. After that, if the key body 1 is inserted into the water meter pre-selling water quantity adjusting hole again, even if the stop piston 6 is pushed by the quantitative mechanism adjusting rod, the up-going position of the limit sleeve 7 is blocked by the locking piston 4 and locked and cannot move upwards, and the spline of the quantitative mechanism adjusting rod cannot normally enter the key body to be meshed with the quantitative adjusting gear ring 5, so that the quantitative mechanism adjusting rod cannot be driven to rotate, and the disposable function is realized.
