Problems solved by technology

[0003] In order to overcome the technical problems that users of existing mechanical time-delay self-closing products cannot adjust the time and volume according to different water pressures and different water-saving requirements or the long-running water is blocked by scale, the present invention provides an adjustable self-closing device for anti-blocking and descaling. Closed water-saving device, which can not only prevent blockage and descaling, but also meet the user's own adjustment of delay time and water volume according to different water pressure or different water saving requirements

Embodiment Construction

[0009] In the accompanying drawings, the cylinder (4) in the valve body is a cylindrical cylinder in the shape of "Shang", and the outer circle is provided with two steps with different outer diameters and a groove for installing an O-shaped sealing ring. The cylinder gland (11) is compressed in the valve body, a valve stem (15) is arranged in the inner hole of the cylinder top, and a piston assembly (18) is arranged in the lower inner wall. The valve stem (15) is a cylindrical hollow valve stem. The upper outer circle of the valve stem is provided with a water seal (3) on the upper part of the valve stem to seal with the inner hole of the upper part of the cylinder (4). Button (10), the inner hole of the button (10) is provided with a top cover (1), the inner hole of the valve stem is provided with a timing needle (2) for adjusting the delay time, and the middle part is provided with a pressure-retaining sealing ring (14) and Pressure relief hole (13), the bottom and the endo...

Abstract

The invention relates to an anti-blockage descaling timing self-closed water saving device, which is a universal mechanical core device for manufacturing various domestic water saving faucets, toilet device flashing valves, a shower valve or other fluid self-closed water-saving products, and consists of a button, a timing pointer, a valve rod, a pressurizing hole spring cleansing pin, a cylinder, a piston assembly, a piston cup ring and a piston guide holder which are connected together. The device not only can prevent blockage and descale automatically, but also can satisfy construction installers and users to adjust the time delay self-closed time or water amount according to requirements on different water pressures and different water-saving amounts; and besides, the device is convenient and practical with zero fault, saves water and has long service life.

Description

Technical field [0001] The invention relates to a universal core device for manufacturing various domestic water-saving faucets, urinal flush valves, shower valves and other fluid self-closing water-saving products, especially the self-closing valve with adjustable anti-blocking and descaling. water fixtures. Background technique [0002] At present, the delay time and water consumption of the known mechanical time-delayed self-closing water-saving taps and flushing valves are all rated by the manufacturer when they leave the factory. The requirement of water saving can be adjusted by itself, which has great limitations. At the same delay time, the one-time water consumption in places with high water pressure will be large, which will cause greater waste, and the one-time water consumption in places with low water pressure will be small. The application effect cannot be achieved, and the aperture of the delay booster hole is easily blocked by scale in places with hard water...
