Abstract
The utility model relates to a rotor dry type water meter with a directly-counting print wheel, which aims to solve the problems that the scale and characters on an indication mechanism of a current same kind product are inconvenient to print and seal; an upper clamping plate is easy to break; and a letter disk has a complex structure. The key points of the rotor dry type water meter reside in that the upper clamping plate of the water meter is buckled with a cover cap where relevant parameters and trademarks are printed. The cover cap can also be applied as a protective cover of the upper clamping plate. The letter disk of the rotor dry type water meter and a worm are fixed into one body. The letter disk is provided with ten circular numbers from 0 to 9. A scale disk of the indication mechanism is not printed on the upper clamping plate but on the letter disk which is meanwhile fixed with the worm. The worm drives the letter disk to rotate. Thus the counting aim is achieved. The rotor dry type water meter which is made of high-quality materials has the characteristics of stable and reliable performances, installing convenience, convenient recovery and better environmental protection. The indication mechanism which is sealed by welding and separated from water can prevent condensation and atomization. The rotor dry type water meter which is magnetically driven and has a strong antimagnetic function is an ideal civil metering device.
Description
Technical field
The utility model relates to multi jet dry type vane wheel water meter, is a kind of multi jet dry type vane wheel water meter of direct character wheel counting.
Background technology
At present, the indicating mechanism of most of multi jet dry type vane wheel water meters is vacuum-packed, and when making the wheel rotation of metering mechanism by magnetic principles, the pointer that drives indicating mechanism rotates simultaneously.As the patent No. ZL200420109472.2 that discloses in the Chinese patent literature, February 8 2006 Granted publication day, Granted publication CN2757098Y, utility model title " a kind of anti-clogging water meter ", this water meter adopts the dry type dial plate, magnetic transmission structure, counting assembly vacuum seal and not contacting with tested water, it is clear, reliable that reading keeps forever.But the inner structure of above-mentioned water meter is comparatively complicated, and all is traditional printing scale dish on train wheel bridge, makes troubles at process aspect.
For this reason, the patent No. ZL200520051705.2 that discloses in the Chinese patent literature for another example, June 27 2007 Granted publication day, Granted publication CN2916588Y, utility model title " water gage glass is literal ", this water meter is because to be that special-purpose corrosion resistant waterproof glass printing ink directly is printed on glass, and die front portion and glass are firmly printed the sealing one, isolate the chance that does not have precipitation and pollute with water or fluid to be measured fully.But above-mentioned housing, indicating mechanism, metering mechanism reclaim comparatively inconvenience, and environment protecting is relatively poor.
Summary of the invention
For overcoming above-mentioned deficiency, the utility model provides a kind of letter disk to be fixed in worm screw to this area, indicating mechanism adopts the multi jet dry type vane wheel water meter of the direct character wheel counting of welded seal, make its scale that solves indicating mechanism in the existing like product and text printout, sealing inconvenience, and train wheel bridge breaks easily and the baroque technical matters of letter disk.Its objective is and be achieved through the following technical solutions.
A kind of multi jet dry type vane wheel water meter of direct character wheel counting, this water meter comprises indicating mechanism and metering mechanism, indicating mechanism and metering mechanism are by the direct magnetic transmission of magnet steel; The mode of above-mentioned direct magnetic transmission has overcome the magnetic phenomenon of taking off of counting mechanism in the existing dry-type meter, has advanced application technology, and resistance to frost is fine, reading, checks meter conveniently, can keep clear reading for a long time, the characteristics of longer service life.Indicating mechanism comprises central gear, train wheel bridge, lower plate, worm screw, letter disk, character wheel; Described upper and lower clamping plate adopt transparent material to make, and upper and lower clamping plate adopt welded seal, are provided with central gear, worm screw, letter disk, character wheel in the seal chamber body that upper and lower clamping plate constitute, and described indicating mechanism is by the direct reading of character wheel.Its design main points are that described train wheel bridge and cover cap fasten, and cover cap prints correlation parameter and trade mark, also can be used as the protective cover of train wheel bridge.Letter disk and worm screw fixedly are connected as a single entity, and letter disk is provided with ten numerals of annular " 0～9 ".The dial of this indicating mechanism is not printed on the train wheel bridge, but is printed on the letter disk, and letter disk is fixed with worm screw simultaneously, drives letter disk by worm screw and rotates together, reaches the purpose of counting.Like this, this water meter is compared with existing water meter, has omitted dial and pointer, has directly adopted the character wheel reading, has reduced parts and production cost, has improved the fastness of indicating mechanism by cover cap.
The water inlet of described watchcase front end is provided with screen pack, is used for the filtration of water body; Be provided with anti-magnet ring between indicating mechanism and the metering mechanism, prevent that the mutual the action of a magnetic field area of magnet steel in indicating mechanism and the metering mechanism is excessive.
The utility model adopts quality matetrial to make, stable performance, reliable, easy for installation, and be convenient to reclaim comparatively environmental protection; Indicating mechanism adopts welded seal, and isolates with water, can prevent the condensation atomizing; Be installed on indoor or outdoors and all can satisfy the supply of the water yield, be used to measure the total amount of water supply pipe Chilled Drinking Water of flowing through, belong to rotary wind type, dry type, magnetic transmission, desirable civilian measuring instrument that antimagnetic function is strong.
