Multifunctional self-closing efficient water-saving valve

Abstract

The invention discloses a multifunctional self-closing efficient water-saving valve, and relates to a water-saving valve. The valve comprises a valve body, a valve core and a hand wheel device, wherein the valve body comprises a valve core outer sleeve, a water inlet pipe, a blow-down bolt, a nano filter screen, a water-saving nozzle and a water outlet pipe; the valve core comprises a valve core inner sleeve, a valve core screw plug, a valve core screw, a valve core screw cap, a screw clamping shoulder, a connecting pipe yoke, a multi-purpose water wheel, a water wheel connecting pipe and a water quantity adjusting rod; the hand wheel device comprises a hand wheel, a water quantity knob and the like; the valve core outer sleeve is positioned in the middle of the valve body; the valve core inner sleeve is arranged in the valve core outer sleeve; the valve core screw plug is arranged in the valve core inner sleeve and can move up and down therein; the multi-purpose water wheel is arranged in a convex water tank; one end of the water wheel connecting pipe is connected with the multi-purpose water wheel, while the other end is arranged in a screw through hole; and the hand wheel is rotated to drive the valve core to open the water valve and the multi-purpose water wheel applies work to automatically close the water valve. The valve has the advantages of exquisite design, excellent performance, wide application, constant pressure, steady flow, micro-filtration and dirt disposal, good water quality, self-closing if forgetting closing, leakage avoidance, water saving, high efficiency, plugging and stealing resistance, firmness and durability.

Description

technical field [0001] The invention relates to a water-saving valve, in particular to a multifunctional self-closing high-efficiency water-saving valve. Background technique [0002] Nowadays, considering that the development of various social undertakings should be carried out simultaneously with the protection of environmental resources, comprehensive energy conservation, pollution reduction, emission reduction, consumption reduction and efficiency enhancement are vigorously advocated, and the protection of water resources, which is known as the source of life, has become increasingly important. People In addition to reducing pollution and excessive exploitation of water resources while protecting water resources, it is also particularly important and urgent to scientifically and rationally use water and increase the overall water-saving rate. At present, the amount of tap water used in urban and rural life, work, production and processing in my country is increasing, and...

Problems solved by technology

[0004] According to comprehensive analysis, the main technical problems of the above two valves are as follows: first, the structure is relatively complicated, not exquisite, the cost of production and sales is high, and it is difficult to maintain; Practical proof that it is very easy to directly affect the normal use of the valve body and water sanitation due to reasons such as low temperature freezing, oil body loss and leakage; third, because the water-saving holes in and out are small and there is no micro-filtration device, it is easy to cause blockage and affect water quality and use over time. Effect; Fourth, both valve cores use springs as the main opening and closing parts. After a long time of use, the spring is prone to failure, which will easily affect the use effect and life; Fifth, the former (the above-mentioned automatic water-saving valve) switch has no automatic return function , when you use it again, you need to turn the switch with your hands before you can boil the water again. Sixth, the functions are relatively single, and the scope of use and effect are limited; Seventh, because there is no definite water supply time within the set self-closing time, it is easy to cause poor use and due to different use environments, objects and water consumption The problems caused by the valve, as well as the non-water adjustment switch of the spool, the long-boiled water function and the anti-theft fixing bolt, etc., directly reduce and affect the comprehensive water-saving efficiency, use effect and scope of use.

In short, although the two valves have their own strengths, their comprehensive technical performance is still relatively lacking, which is not conducive to long-term promotion and use.
