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

[0015] refer to figure 1 , figure 2 with 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 with 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 mec...

Abstract

The invention relates to a passive automatic-control liquid flowmeter. A limiting rotary shaft of a quantification mechanism is fixed on a rotary gear and connected with a quantification spring. A rotary shaft gear is linked with a combination ratchet which is linked with and drives transition gears. A positioning wheel of a positioning control mechanism is fixed on a limiting rotary shaft. A positioning groove is formed in the positioning wheel. A positioning block is arranged on a closing board and matched with the positioning groove to control the closing board to open and close. A water inlet of a meter body is provided with an inner valve cavity with an opening in the longitudinal direction. The closing board and the opening of the inner valve cavity are closed. The closing board is fixed in the meter body and can rotate. A reset spring is arranged outside of a cavity hole of the inner valve cavity and connected with the closing board. The passive automatic-control liquid flowmeter has following beneficial effects: due to the fact that the inner valve cavity is arranged in the meter body and the closing board is transversely arranged in a cavity port of the inner valve cavity in the meter body, the closing board cannot be seen from a liquid inlet of the flowmeter; the closing board cannot be prided laterally from the liquid inlet; a sealing effect is improved; and water is prevented from being stolen and leaked.

Description

Technical field [0001] The invention relates to a passive self-control liquid flowmeter. Background technique [0002] 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 the rotat...
