Description
Technical Field
The utility model belongs to the technical field of the water gauge counter manufacturing technology and specifically relates to indicate an adjustable flow piston counter.
Background
The piston type meter generally comprises a piston box, a filter screen arranged at the bottom of the piston box, a piston arranged in the piston box, a central shaft and a shifting tooth, wherein water flows through the filter screen to filter impurities such as sand, stone, leaves and the like in water, the impurities enter the metering chamber from a water inlet of the piston box, an emptying water inlet cavity and a water outlet cavity are filled in sequence to push the rotary piston to do rotary motion around the central shaft of the metering chamber, meanwhile, water flows to an upper water outlet from a hollow part in the piston and a hollow part formed by the piston and the wall surface of the metering chamber, and the central shaft and the shifting tooth are connected with a counter when the piston rotates, so that the volume of the water meter can be calculated through the counter as long as the number of times. At present, piston type water meter meters are subjected to finish machining after injection molding, and are subjected to verification after assembly is completed, so that the machining precision of products is greatly improved, if the verification is unqualified, secondary machining needs to be performed on all parts of the meters, and part of the parts can become reported waste products, so that the manufacturing cost is high.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
An object of the utility model is to provide an adjustable flow piston counter is through addding the regulation hole in piston box bottom, through the size of adjusting the regulation hole to make water gauge metering error meet the standard, and then promote check-up qualification rate, not only reduced the machining precision requirement, avoided secondary operation and scrapped simultaneously, greatly reduced manufacturing cost. In order to achieve the above purpose, the utility model adopts the following technical scheme:
(II) technical scheme
The utility model provides an adjustable flow piston counter, includes piston box, sets up the piston in the piston box and with the apron of the mutual block of piston box, piston box bottom is equipped with the water inlet, be equipped with the delivery port on the apron, be equipped with adjusting part in the piston box bottom, adjusting part includes regulation hole and regulating plate, the regulation hole sets up water inlet one side, the regulating plate passes through adjusting screw to be fixed on the piston box, just the regulating plate can cover completely around adjusting screw is rotatory adjusting hole.
Further, the adjusting plate is in a fan-shaped design.
(III) advantageous effects
Compared with the prior art, the utility model have obvious advantage and beneficial effect, particularly, the utility model discloses an add the regulation hole in piston box bottom, through the size of adjusting the regulation hole to make water gauge metering error meet the standard, and then promote the check-up qualification rate, not only reduced the machining precision requirement, avoided secondary operation simultaneously and scrapped, greatly reduced manufacturing cost.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
Referring to fig. 1 and 2, an adjustable flow piston type meter includes a piston box 1, a piston 2 disposed in the piston box 1, and a cover plate 3 engaged with the piston box 1, the piston 2 is connected to a central shaft 4, the central shaft 4 is connected to a gear shifter 5, the gear shifter 5 is convenient for connecting to a counter, the cover plate 3 is provided with a water outlet 31, the bottom of the piston box 1 is connected to a filter screen 6, the bottom of the piston box 1 is provided with a water inlet 11, the bottom of the piston box 1 is provided with an adjusting assembly 12, the adjusting assembly 12 includes an adjusting hole 121 and an adjusting plate 122, the adjusting hole 121 is disposed at one side of the water inlet 11 and penetrates through the bottom of the piston box 1 to communicate with a metering chamber, the adjusting plate 122 is fixed on the piston box 1 by an adjusting screw 123, and the adjusting plate 122 can rotate around the adjusting screw 123 and completely cover, to facilitate the rotational covering, the adjustment plate 122 is fan-shaped.
The utility model discloses flow control principle: most of the water flow enters the metering chamber through the water inlet 11 to drive the piston 2 to run, a small part of the water flow directly enters the metering chamber through the adjusting hole 121 to adjust the metering error of the water meter, and then the whole water flow flows out of the water outlet 31, wherein the size of the small part of the water flow is determined by adjusting the size of the adjusting hole 121 through the adjusting plate 122.
The utility model discloses an add the regulation hole in piston box bottom, through the size of adjusting the regulation hole to make water gauge metering error meet the standard, and then promote the check-up qualification rate once, not only reduced the machining precision requirement, avoided secondary operation and scrapped simultaneously, greatly reduced manufacturing cost.
