Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] Such as Figure 1~4 As shown, the present invention includes an emitter main body 1 , a pressure compensating membrane 2 , a water outlet ring cavity 3 and a movable coil 4 . One end of the emitter main body 1 is provided with a fixed coil 5, and the other end of the emitter main body 1 is connected with a movable coil 4 by threads. A first labyrinth channel 6 is arranged on the outer wall of the emitter body 1 between the fixed coil 5 and the movable coil 4, and the beginning and end of the first labyrinth channel 6 is a water inlet communicating with the interior of the emitter body 1 7. The water outlet annular cavity 3 is arranged outside the emitter main body 1 between the fixed coil 5 and the movable coil 4 . The pressure-compensating membrane 2 ring is set between the water outlet ring chamber 3 and the emitter main body 1 and both en...

Abstract

The invention relates to a detachable and washable combined pressure compensation emitter between tubes. The emitter comprises an emitter body, a pressure compensation film, a water outlet annular cavity and a flexible screw tube; a fixed screw tube is arranged at one end of the emitter body, and the flexible screw tube is connected to the other end of the emitter body through threads; a first labyrinth channel is formed in the portion, located between the fixed screw tube and the flexible screw tube, of the outer wall of the emitter body, and the head and tail of the first labyrinth channel are water inlets communicated with the interior of the emitter body; the water outlet annular cavity is formed in the outer portion, located between the fixed screw tube and the flexible screw tube, of the emitter body; the pressure compensation film is arranged between the water outlet annular cavity and the emitter body in an annular mode, and both ends of the pressure compensation film are limited by the fixed screw tube and the flexible screw tube; a second labyrinth channel is formed in the inner wall of the water outlet annular cavity, and the tail end of the second labyrinth channel is a water inlet communicated with the outer portion of the water outlet annular cavity; a film flow passing hole which enable the first labyrinth channel to be communicated with the second labyrinth channel is formed in the pressure compensation film.

Description

technical field [0001] The invention relates to a detachable and washable combined pressure compensation sprinkler between pipes, which belongs to the technical field of agricultural irrigation. Background technique [0002] my country is facing a severe water shortage problem. As a large water user, agricultural irrigation has increasingly prominent contradictions between supply and demand, and the effective utilization rate of agricultural irrigation water is low, so water-saving irrigation emerges as the times require. Drip irrigation is the micro-irrigation method with the highest water-saving efficiency at present, and the water utilization rate can be as high as 95%. It is an important technical measure to ensure the sustainable development of agriculture in our country. The emitter is the core and key part of the entire drip irrigation system, and its structure has a great influence on the uniformity of irrigation, the anti-clogging ability and life of the system. Th...
