Water Conservation Act Including Improved Automatic Pressure Regulators

Abstract

It relates to a water-saving method including an improved automatic pressure regulator, because the automatic pressure regulator (58) is sequentially provided with a filter screen (58d), a water-through inner plug (58c), a movable pressure regulator (58) from the water inlet to the water outlet Plug (58a), pressure regulating spring (58f), return water pressure chamber (58g), water reaches the nozzle after the automatic pressure regulator, and the water pressure required by the movable pressure regulating plug (58a) at the water outlet nozzle is greater than and When it is equal to the water pressure provided by the water inlet end, under the action of the pressure regulating spring (58f), it is away from the filter screen (58d) and the water inner plug (58c) to ensure the maximum water flow; when the water outlet nozzle and water When the water pressure required by the device is lower than the water pressure provided by the water inlet end, the excess water will flow into the return water pressure chamber (58g) and push back the movable pressure regulating plug (58a) under the action of back pressure to approach the water return pressure chamber (58g). Said water-through inner plug (58c) is until pressure balance on both sides, promptly protects water outlet nozzle and water device to be beneficial to water saving and pressure overload protection.

Description

technical field [0001] The invention relates to a control method of water flow for environmental protection and landscaping, which is a water-saving method including an automatic pressure regulator, including a 360-degree nozzle, a joint that can fine-tune the size and pitch of a threaded ring, and its connection with the Equipped with an energy-saving sprinkler timer and a water distributor with a multi-purpose interface, it is convenient for efficient garden irrigation, energy saving and water saving. Background technique [0002] The desire to pursue environmental protection and landscaping is endless; there are also many patents on the control method of watering water flow, and the timing switch of garden sprinklers controlled by both sides of the long axis, such as patent US7252113B2, and Patent ZL200820120164.8 all adopts the timing switch of the garden sprinkler controlled by both sides of the long axis. Although the mechanical timer is widely used because of its fir...

Problems solved by technology

Existing products vary, and none of them are perfect; there is a certain nozzle (55ac), such as Figure 31 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ac) through the matching components and then sprayed out through the only small square hole provided on the nozzle cap as the water nozzle (55a3c). Its disadvantage is that the range of sprayed water is narrow, and it cannot have a 360-degree all-round irrigation effect.

Another nozzle (55ad) for existing products, such as Figure 32 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ad) through the matching components, and is sprayed out through the large through hole opened on the half side of the nozzle cap as the water nozzle (55a3d) , its shortcoming is that the range of sprayed water is only half, and cannot have a 360-degree all-round irrigation effect

Sprinkler cap (55ab) of another sprinkler head of the preliminary improved product, such as Figure 29 As shown, the water is connected to the nozzle seat and the movable nozzle ball of the certain nozzle (55ab) through the matched parts, and passes through the multiple through holes around the ring set on the nozzle cap as the water nozzle (55a3). In order to make the water balance and self-regulation, it is desirable to set a movable nozzle ball in the center of the nozzle, but because the center of the inner top of the nozzle cap is provided with a cone pointing downwards, that is, towards the nozzle ball, although the ball can be moved Free and easy to control, but the tip of the cone tends to be biased against the movable nozzle ball. The water spray of another nozzle of the preliminary improved product is still insufficient, and the range of water sprayed is only half. Can not have 360-degree all-round irrigation effect
