Abstract
The utility model relates to an anti-dropping device together used for running water and a water meter. A cylinder body is arranged in a cavity body composed of a valve body and a cover, a piston mechanism is arranged in the cylinder body, and a spring is arranged on a piston of the piston mechanism. The utility model is mainly used for matching with the water meter of a user using the water supply of running water.
Description
Affiliated technical field
The utility model belongs to liquid water clock intelligent apparatus technical field.
Background technology
Tap water supply generally adopts by the pattern of big water meter to little water meter at present, little water meter is installed in the resident family, the Total Water of the Total Water of for various reasons little water meter and big water meter, there is difference more, if any the user dripping phenomenon appears, on little water meter, do not show, but many families are when occurring leaking, will form big current, on big water meter, will count.In order to overcome this situation, little water meter also can show counting when dripping.All intelligent drop/leakage prevention devices owing to complex manufacturing, are difficult for forming and produce in batches at present.
Summary of the invention
In order to overcome the prior art complex manufacturing, be difficult for forming the defective of producing in batches, for this reason, the utility model improves from process structure, and the product technology after the improvement is simpler, is easy to form produce in batches.
The technical scheme that the utility model adopted is, describe according to accompanying drawing, the utility model is to be screwed by screw thread by valve body 10 and lid 1 to be connected into a cavity, seal with O-ring seal 5, in cavity, there is cylinder body 2 to be fixed on the valve body, seal by O-ring seal 9, have water delivering orifice 14 on the cylinder body, installed in cylinder body by O-ring seal 7, magnetic element 6 and piston 4 are formed the piston mechanism of one, spring 3 is contained in above the piston, one end and the cylinder body inner top surface of spring contact, and have water inlet 11 on valve body 10,13, water delivering orifice 12, constituted the A chamber by intake tunnel, constituted the B chamber by exhalant canal.When tap water flows to the A chamber from water inlet 11 along intake tunnel, the power F that hydraulic pressure produces acts on the magnetic element, when water pressure has overcome the magnetic field force that the elastic force of spring 3 and magnetic element produce, with piston mechanism jack-up to cylinder body water delivering orifice place 14, Open valve, tap water will flow out along exhalant canal.When water delivering orifice was closed, A chamber and B cavity pressure kept balance, and piston mechanism covers A chamber water inlet under the effect of magnetic element magnetic field force, and O-ring seal 7 plays sealing function, and A chamber and B chamber are in the partition state.When the water delivering orifice unlatching has minor amount of water to flow out, water in the B chamber flows out under self pressure, when the hydraulic pressure in the B chamber low to a certain degree the time, water pressure in the A chamber is during greater than the hydraulic pressure in the B chamber, piston mechanism is backed down, when the hydraulic pressure in A chamber and the B chamber tended to balance, piston mechanism slowly moved down, and covered the water inlet in A chamber.Weep or water clock take care of the pence in the antidrip device and spill out like this, can effectively measure.
The beneficial effects of the utility model are that it can be used with common water meter, can current, the water droplet that be lower than water meter initiating flow effectively be measured.To safeguarding the interests of water supply department, using water wisely plays a positive role.
