Embodiment Construction

[0016] The present invention will be described in further detail below by means of specific embodiments:

[0017] The reference numerals in the drawings of the specification include: end cap 1 , rubber ball 2 , baffle plate 3 , housing 4 , sealing ring 5 , upstream shell 6 , downstream shell 7 , cavity 41 , and barb 61 .

[0018] The embodiment is basically as figure 1 Shown: a capillary pressure regulator, including an upstream casing 6, a downstream casing 7, and a pressure regulating assembly. The upstream casing 6 is in the shape of a hollow barrel, and the outer wall of the upper end of the upstream casing 6 is provided with a circle of barbs 61, which are used to fix the water pipe To prevent the water pipe from falling off from the upstream shell 6, the outer wall of the lower end of the upstream shell 6 is provided with external threads. Downstream casing 7 is hollow barrel shape, and the right end of downstream casing 7 is provided with a circle of barb 61, and barb ...

Abstract

This patent specifically discloses a capillary pressure regulator, including an upstream casing, a downstream casing and a pressure regulating assembly. The upstream casing is in the shape of a hollow barrel, and the outer wall of the lower end of the upstream casing is provided with external threads. The downstream casing is in the shape of a hollow barrel. External threads are provided on the outer wall of the left end of the downstream housing. The pressure regulating assembly includes a housing, a baffle and a rubber ball. The housing is formed with a hollow cavity. The upper part of the housing is provided with a thread that is threadedly connected with the upstream housing. The side of the shell is provided with a threaded hole threaded with the downstream shell, the upstream shell, the downstream shell and the cavity of the shell are connected, the baffle is placed in the cavity and hinged on the shell, the rubber ball is placed Inside the cavity and below the baffle. The pressure regulator has a low starting pressure due to its sensitive response, which not only satisfies agricultural irrigation, but also uses rubber balls as elastic recovery parts to be more reliable.

Description

technical field [0001] The invention relates to the field of agricultural irrigation equipment, in particular to a capillary pressure regulator. Background technique [0002] Irrigation uniformity is an important indicator for evaluating the performance of drip irrigation systems. However, due to the different distances between the pipes and the head of the system and the undulations of the terrain, the inlet pressures of different branch pipe inlets and different capillary pipe inlets vary greatly, which leads to water discharge from field drippers. Uneven flow affects the uniformity of irrigation in the drip irrigation system. In order to effectively control the irrigation uniformity of the drip irrigation system, the existing technical solutions are pressure regulation and flow regulation. [0003] CN 201310017540.6 discloses a capillary pressure regulator with stable pressure regulating performance, which is characterized in that it includes an upstream housing, a downs...
