Abstract
The utility model discloses a flow regulating mechanism of a water meter. The water meter comprises a shell and a core, wherein a cavity limited by the shell is divided into a water meter upper cavity and a water meter lower cavity by a horizontal annular plate; the core is arranged in the water mete upper cavity; the annular plate is provided with a through hole which runs through vertically; a horizontally run-through threaded hole is formed on the upper part of the through hole or on a shell body of the shell of the upper part; a regulating bolt which is matched with the threaded hole penetrates through the shell body of the shell from the exterior and the inner end part of the regulating bolt is positioned on a flow passage of the through hole. According to the flow regulating mechanism, the through hole is formed on the partition annular plate of the water meter upper cavity and the water meter lower cavity, regulation of accuracy of the water meter is realized by utilizing water flow which does not pass through the core, the regulation can be realized by only turning a regulating screw, and the meter body is not required to be disassembled; because of hidden design of the regulating screw, the regulation can be performed by poking with a tool; and thus, error operation during use of a user can be avoided, and the metering accuracy is improved.
Description
Technical field
The utility model relates to a kind of water meter, relates in particular to a kind of valve integrated plastic water meter flow control device of showing.
Background technology
At present, known plastic water meter is made up of watchcase, movement, middle cover, glass and packing washer, in production or maintenance process, need adjust the precision of water meter sometimes.Chinese patent 201020258618.5 discloses a kind of movement that is used to regulate watermeter flowing rate; Comprise that the bottom has water outlet flange impeller box; Also comprise a filtering screen that covers on the impeller box; Have some apopores on the said water outlet flange, said filtering screen bottom has some inlet openings that can be connected with apopore, is used to regulate watermeter flowing rate.
But regulate the water meter precision through movement, need cover in the water meter be unclamped and regulate, relatively lose time; There is the people also to adopt external adjusting bolt to regulate the water meter precision in the prior art,, regulates, in use turned on, cause metering to be forbidden by the user than being easier to than being easier to though need not unclamp middle cover during through external adjusting bolt.
Summary of the invention
The technical matters that the utility model will solve provides a kind of simple in structure and can fast adjust the flow regulator of water meter precision.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of watermeter flowing rate governor motion; Described water meter comprises shell and movement; The inner chamber of described shell limitation is divided into water meter epicoele and water meter cavity of resorption by the annular slab of level; Described movement is arranged in the water meter epicoele; On said annular slab, offer the through hole of up/down perforation, and the case body on described through hole top or top is provided with the threaded hole that level connects, passes case body from the outside and its inner end is positioned on the runner of through hole with the adjusting bolt of described threaded hole coupling.
Preferably, described water meter is the valve integrated formula water meter of table, and it comprises the table body and the valve body of adjacent setting and connection.
Preferably, described annular slab through hole placement is provided with the semi-circular recesses corresponding with described threaded hole.
Preferably, be formed with and can described adjusting bolt outer end be held the cavity in it in described housing exterior.
The utility model is through being provided with through hole on the ring flat-plate in cutting apart of water meter upper and lower cavity; Utilize and do not realize adjustment, only need rotate the adjustment screw during adjustment and can realize, need not the table body is taken apart the water meter precision through the current of movement; And the concealed design of adjustment screw; Adjustment needs instrument can stir adjustment, and maloperation when this is just avoided the user to use improves metering precision.
Description of drawings
Fig. 1 is the valve integrated formula water meter structure of the table of a utility model synoptic diagram;
Shown in Figure 2 is the local enlarged diagram of A portion shown in Figure 1.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and embodiment.
Like Fig. 1, shown in 2; The valve integrated formula water meter of the table of the utility model comprises the table body 1 and valve body 2 of adjacent setting and connection; Described table body and valve body are formed by the injection moulding of plastics one; Described table body comprises shell 11, movement (not shown), middle cover 13 and with described middle cover upper shed sealed glass 14; The inner chamber of described shell limitation is divided into water meter epicoele 12 and water meter cavity of resorption 16 by the annular slab 6 of level, and described movement 12 is arranged in the water meter epicoele, and it comprises impeller box, impeller sum counter assembly etc.; Pass in the laggard process of going into the water meter epicoele of the center pit of annular slab 6 from the water that water inlet gets into the water meter cavity of resorption, the current that pour in can be stirred the purpose that wheel rotation realizes counting then.
For realizing adjusting to the water meter precision; The through hole 7 that offers up/down perforation on the annular slab 6 in cutting apart of described water meter upper and lower cavity; And the case body on described through hole 7 tops or top is provided with the threaded hole 9 that level connects, and regulates bolt 8 coupling ground and passes case body from the outside its inner end is positioned on the runner of through hole 7.
Because the position of through hole 7 is opened in the movement outside; Current from through hole 7 flows in the water meter epicoele can be to impeller generation effect; The precession of through hole regulating and controlling bolt 8 or the length that screws out, effective flowing water that can change through hole 7 is realized the adjustment to watermeter flowing rate through area.
Only be to have illustrated a water meter precision to regulate bolt in the drawings,, two or more above-mentioned precision adjusting device can be set for improving its adjustable extent.
Further; Regulate the degree of regulation of bolt for improving to through hole 7 flows; Described annular slab through hole 7 placements are provided with the semi-circular recesses corresponding with described threaded hole; It keeps closely contacting with the semi-circular recesses of annular slab in the precession process promptly to regulate bolt, and the threaded engagement of the groove of annular slab and adjusting bolt can realize whole sealings of through hole improving its regulating effect.
Further, for preventing user's false touch, be formed with and can described adjusting bolt outer end be held the cavity in it in described housing exterior, this cavity will be regulated the outer end Hide All of bolt, can effectively avoid maloperation.
The utility model is through being provided with through hole on the ring flat-plate in cutting apart of water meter upper and lower cavity; Utilize and do not realize adjustment, only need rotate the adjustment screw during adjustment and can realize, need not the table body is taken apart the water meter precision through the current of movement; And the concealed design of adjustment screw; Adjustment needs instrument can stir adjustment, and maloperation when this is just avoided the user to use improves metering precision.
By the above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
