Embodiment Construction
[0022] The preferred implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] The present invention adopts the following technical solutions: a capillary inlet pressure regulator, such as figure 1 As shown, the present invention includes an upstream deflector 1 , a pressure regulating assembly 2 , a downstream housing 3 and a spring 4 .
[0024] Such as Figure 6 As shown, the upstream diversion body 1 is a tubular structure, and its outer walls have different diameters. The diameter of the central part is larger than the diameters of the two ends. One end is the connection end 13 of the pressure regulating assembly; a barrier 14 is arranged inside the upstream guide body 1 and behind the shell connection end 11, and the barrier 14 divides the interior of the upstream guide body into upper chambers 15 that are not connected to each other and the lower cavity 16; the side wall of the upper cavity...

The invention relates to a hollow billet inlet pressure adjuster in the field of agricultural water-saving irrigation. The hollow billet inlet pressure adjuster is characterized by comprising an upstream flow guide body, a downstream shell, a pressure adjusting component and a spring. A baffle separating the interior of the upstream flow guide body into an upper cavity and a lower cavity is disposed inside the upstream flow guide body. The peripheral outer wall of the upper cavity is provided with water outlets. An air guide pipe communicating the lower cavity and atmosphere is disposed inside the upper cavity. The middle portion of the upstream flow guide body is connected with the downstream shell. The end of the upstream flow guide body is connected with the pressure adjusting component in a sealed manner. The downstream shell comprises a first cylinder and a second cylinder. U-shaped guide grooves are formed in the peripheral inner wall of the first cylinder. The end of the second cylinder is used as a water outlet end. Guide columns are disposed on the peripheral outer wall of the pressure adjusting component and embedded into the U-shaped guide grooves of the downstream shell. The spring is mounted in the space formed by the upstream flow guide body and the pressure adjusting component. The pressure adjuster mounted on the inlet of hollow billet is low in adjusting starting pressure, wide in adjusting range, good in pressure adjusting pressure, simple in structure, suitable for being popularized widely, and capable of greatly increasing irrigation evenness.
Description
technical field [0001] The invention relates to a pressure regulator in the field of agricultural water-saving irrigation, in particular to a capillary inlet pressure regulator with simple structure. Background technique [0002] In the drip irrigation system, due to the distance between the irrigation area and the head water source, as well as the terrain fluctuations, the inlet pressure of the irrigation area is different, which further causes the pressure of the capillary inlet and the dripper to change greatly, resulting in that the uniformity of irrigation does not meet the specification requirements. . In order to effectively control the irrigation uniformity of the entire drip irrigation system, the existing technical solutions mainly include the use of pressure compensation drippers, branch pipes, and capillary pressure flow adjustment devices. The cost of pressure compensation dripper is high, and it is not suitable for large-scale promotion at this stage; the bran...
