Description

An anti-disturbance high-sensitivity water meter

technical field

The utility model relates to the technical field of instrument equipment, in particular to an anti-disturbance high-sensitivity water meter.

Background technique

With the continuous development of industrial economy and urban scale, water meters are being installed and used more and more widely in industrial and residential life as instruments for measuring water flow. The water meter on the market mainly drives the impeller to rotate through the water flow, which drives the gear on the counter to rotate to measure the water consumption.

The water meters on the market are not equipped with anti-backflow devices, which will cause water meter disturbances during actual use. The so-called water meter disturbance refers to the phenomenon of water meter rotation caused by pressure imbalance on both sides of the water meter. Some users, taking advantage of the fact that the water meter is not equipped with an anti-backflow device, impose measures to reduce the water indication on the water meter; on the other hand, when using this type of water meter, when the water flow is small, the water flow through the filter cover is not enough to drive the impeller to rotate. Cause measurement error, some users take advantage of this defect to steal water, bring losses to the country.

detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Figure 1 is a schematic structural diagram of the anti-disturbance high-sensitivity water meter provided by the utility model, as shown in Figure 1: the utility model provides an anti-disturbance high-sensitivity water meter, including an anti-backflow assembly 1, a blade wheel assembly 2, and a gear assembly 3; The anti-backflow assembly 1 includes a filter cover 101, a first baffle 102 and a second baffle 103, the bottom of the filter cover 101 is provided with a through hole 104 as a water inlet; the first baffle 102 is located in the through hole Above 104, it is used to prevent the disturbance of the water meter; the side wall of the filter cover 101 is provided with an oblique water inlet hole 105, and the inner side of the oblique water inlet hole is provided with a card slot 106, and the second blocking piece 103 is arranged in the card slot , as shown in Figure 2, used to prevent water from flowing backward; the blade wheel assembly 2 includes a blade wheel 201 and a blade wheel box 202, the blade wheel 201 is placed inside the blade wheel box 202, and the blade wheel box 202 is placed in Inside the anti-backflow assembly 1 ; the gear assembly 3 includes a gear set 301 , a gear box 302 and a gear set panel 303 , the gear box 302 is sleeved on the upper part of the vane wheel box 202 through the blade wheel shaft, so The gear set 301 is arranged in the gear box 302, and the gear set panel 303 is arranged on the upper part of the gear assembly 3, and includes a plurality of gear scales thereon.

During specific implementation, when a user uses water, the water flows in from the through hole 104 and the oblique water inlet hole 105 . When water flows in from the through hole 104 , the first blocking plate 102 is no longer attached to the bottom of the filter cover 101 under the action of water pressure, and water can enter through the through hole 104 smoothly. When the user does not use the water, the water will no longer flow. Under the condition of internal and external pressure balance, the first blocking plate 102 will be attached to the bottom of the filter cover 101 again, and the remaining water in the water meter will not flow back. Unbalance will not disturb the water meter. Since the two protrusions 107 on the top of the second blocking piece 103 are locked on the slot 106, the second blocking piece 103 can rotate around the protrusions to the inside of the filter housing 101 at a certain angle. When water entered from the oblique water inlet 105, the second catch 103 was under the hydraulic pressure, and the second catch 103 deflected to the inside of the filter cover 101 around the protrusion 107, and the water flow entered from the oblique water inlet 105 smoothly. When the user does not use the water, the water no longer flows. Under the condition of internal and external pressure balance, the second baffle 103 is tightly attached to the side wall of the filter cover 101 again, the remaining water in the water meter will not flow back, and the water pressure in the water inlet pipe outside the water meter will The imbalance of the water meter will not cause disturbance.

Because there is only one oblique water inlet hole 105 on the side wall of the filter cover, so when the water flow rate is very small, a large water pressure can also be formed at the oblique water inlet hole 105, so that the blade wheel 201 can rotate normally, and the user cannot use the small water flow to steal. water. On the other hand, due to the existence of the first baffle 102 and the second baffle 103, when the user removes the water meter and passes water from the water outlet of the water meter to the water inlet, the first baffle 102 and the second baffle 103 will both Close to the filter cover 101, the water flow cannot flow out, and the user cannot steal water by changing the water indication number.

The anti-disturbance high-sensitivity water meter provided by the utility model does not generate disturbance of the water meter, has high measurement accuracy, and the user cannot steal water and does not cause losses to the country.

Fig. 3 is a schematic diagram of a preferred embodiment of the bottom of the filter cover in Fig. 1. In practice, the through-hole 104 is a mesh-like through-hole, which is used to prevent dirt in the water from entering the water meter core. The mesh through-holes can filter dirt and prevent dirt from entering the water meter core and affecting measurement accuracy.

It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting it; although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technology of the various embodiments of the present invention. scope of the program.
