As further improvement of the utility model, the lower end can be installed in the center pit of described impeller to be dome shape and to be butted on the lining of showing the body inwall, be provided with the bearing that supports impeller shaft in this lining, and the upper end of lining is equipped with above-mentioned main transmission magnet steel, and the lining outside the main transmission magnet steel is provided with itself and the fastening all-in-one-piece magnetic steel sleeve of impeller.Such structure has replaced original top back shaft, can make impeller be in the plumbness of self all the time and the sensitivity that improves complete machine.
Do this another kind of improvement of the present utility model, described main transmission, be enclosed within on the respective end of described lining and sun gear shaft respectively loosely by the transmission magnet steel, under different rotating speeds, two magnetic are coupled preferably and transmission stably like this, to improve measuring accuracy.
Described gland nut can be screwed onto the middle part of table body by the O-ring seal that is arranged on table body inwall step place.Simple in structure like this, easy for installation, and sealing is reliable.
Described water-in and water-out Kongzui is in well on the same horizontal line and is bypass structure, to reduce resistance to water-flow.
Place, described inlet opening can be equipped with water strainer.
Compared with prior art, advantage of the present utility model is: adopt antimagnetic coil structures, two magnet steel are overlapped within it fully, thereby prevented the interference of extraneous strong magnetic to magnet steel effectively, guarantee the accuracy of measuring.And adopt lining and magnetic steel sleeve, and can make impeller remain the plumbness of self, when improving machine sensitivity, also prevented the influence that transmission is produced to magnet steel of the dirt in the water; Moreover two magnet steel adopt the connected mode of loosening structure, can improve the stability and the measuring accuracy of two magnet steel coupling.And adopt bypass structure into and out of the water hole, can make water that the place, inlet opening flows into after promoting impeller, directly flow out from apopore, need not again circuitously, thereby resistance to water-flow is little, water outlet is smooth and easy, this bypass structure also is convenient to install and use simultaneously.In addition, water strainer is installed in the place, inlet opening, can stops dirt to enter in the table body, effectively to guarantee to show the cleanliness of body; Thereby of the present utility model practical, be worth on water meter, applying.
