Obviously, the structure of above water meter movement has many unreasonable parts, still needs to do further improvement.
Summary of the invention
Technical problem to be solved in the utility model is the half liquid-sealing water meter movement that the band signal transmitter that a kind of sight line is effective and measuring accuracy is high is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of half liquid-sealing water meter movement with signal transmitter, comprise the sampling circle that is installed on the gearcase, the inner peripheral surface of sampling circle is provided with left tongue tube and right tongue tube, the sidepiece of sampling circle is provided with the output line that links to each other with right tongue tube with left tongue tube, counter assembly is installed in the gearcase, counter assembly comprises character wheel, four or eight gear wheels, magnet steel pointer and index dial, it is characterized in that: the inner peripheral surface of described sampling circle is provided with in order to left seal box that left tongue tube and right tongue tube are installed and right seal box, described left seal box and right seal box guarantee simultaneously that along the center symmetric arrangement of magnet steel pointer rotation left seal box and right seal box are positioned at the index dial both sides and index dial is exposed within view fully.
As improvement: with described character wheel and the present situation that four or eight gear wheels contact with water fully, change character wheel in the above-mentioned counter assembly and four or eight gear wheels into and be installed in a filling and have in the seal chamber of clean liquid, the sealing cavity is positioned at gearcase.Completely cut off fully and made contacting of water, can prevent to influence because of water quality is muddy in actual use the character wheel reading, thereby the display part that makes character wheel can keep forever clear, and can also prevent from use to block character wheel and the rotation of four or eight gear wheels because of the tiny foreign material in the water, do not caused and measured, the generation of above problem has been avoided in this technological improvement of process, has guaranteed the reliability of metering.
The upper surface of said gear box is provided with concave part, described magnet steel pointer and index dial are positioned at this concave part, the bottom of described sampling circle is provided with two locating shafts, and after the sampling circle was installed on the gearcase, the madial wall retaining of each locating shaft and concave part was equipped with the sampling circle circumferentially spacing on gearcase.This structure is convenient to the sampling circle is positioned on the gearcase.
For improving the liquid sealing effect between sampling circle and the gearcase, be provided with packing washer between above-mentioned sampling circle and the gearcase.
Compared with prior art, advantage of the present utility model is: the angle that changes two seal boxes of sampling circle dress tongue tube, the pointer of gearcase and index dial are exposed fully show that within view sight line is clearer, prevented the generation of error in dipping, guarantee the accuracy of measuring.
