Problems solved by technology

Although this device realizes the quantitative control of liquid flow, this technology also has disadvantages. For example, when it is applied to the water meter in daily life, because the closing plate of the device can only seal the water inlet of the water meter longitudinally, if When there is bad user behavior, the closing plate can be artificially pried off from the liquid inlet, resulting in quantitative control distortion and troubles to management

Embodiment Construction

[0016] refer to figure 1 , figure 2 and image 3 , the passive self-controlled liquid flow meter includes a meter body 7, in which a quantitative mechanism and a positioning control mechanism are arranged, and the quantitative mechanism includes a limit shaft 1, a quantitative spring 2, a shaft gear 3, a combined ratchet 4 and a transition gear 5 composition, where, refer to Figure 4 and Figure 5 The combination ratchet 4 is composed of a one-way internal and external gear 17 and a three-claw ratchet 18. The three-claw ratchet 18 is installed and fixed on the internal teeth of the one-way internal and external gear 17 to form a combined ratchet 4, and the limit rotating shaft 1 is fixed on the rotating shaft The gear 3 is connected with the quantitative spring 2, the rotating shaft gear 3 is connected with the combination ratchet 4, and the transition gear 5 is driven by the one-way internal and external gear 17 in the combination ratchet 4; the positioning control mecha...

Abstract

The invention relates to a passive self-control liquid flow meter, the limiting rotating shaft of the quantitative mechanism is fixed on the rotating shaft gear and connected with the quantitative spring, the rotating shaft gear is connected with the combined ratchet, and the combined ratchet is connected to drive the transition gear; the positioning control mechanism The positioning wheel is fixed on the limit shaft, the positioning wheel has a positioning groove, and the closing plate is provided with a positioning block, and the positioning block cooperates with the positioning groove to control the opening and closing of the closing plate; Valve cavity, the opening of the inner valve cavity is in the longitudinal direction, the closing plate is closed with the opening of the inner valve cavity, the closing plate is fixed in the watch body and can rotate, the return spring is arranged outside the cavity of the inner valve cavity, and the return spring is connected with the closing plate. Since there is an inner valve cavity in the meter body, the closing plate is arranged horizontally at the inner valve cavity opening inside the meter body, and the closing plate cannot be seen from the liquid inlet of the flow meter at all, which prevents the artificial flow from the side of the liquid inlet. To pry open the closing plate, and strengthen the sealing effect better, so it has a good effect of preventing water leakage.

Description

[0001] Technical field [0002] The invention relates to a passive self-control liquid flowmeter. Background technique [0003] In the invention patent of "a liquid flow quantitative control device" with the patent number ZL200420087258.1 and the invention patent of "a liquid flow quantitative control device" with the patent number ZL200810109516.4, a mechanical liquid flow quantitative The control device mainly includes a quantitative mechanism and an early warning positioning control mechanism. The quantitative mechanism is mainly composed of a limit shaft, a quantitative spring, a shaft gear, a combined ratchet and several gears. The combined ratchet system is composed of a unidirectional internal and external gear and a ratchet. The ratchet is fixed on the gear; the early warning positioning control mechanism is mainly composed of a pressure rod, a return spring, a closing plate and a positioning wheel; in the quantitative mechanism, the limit rotating shaft is fixed on th...
