Self-control type water outlet valve for water outlet pile

Abstract

The invention relates to a self-control type water outlet valve for a water outlet pile, belongs to the technical field of agricultural irrigation, and discloses a water outlet valve for controlling the water outlet amount of the water outlet pile in the process from the underground to the ground in a self-control mode. The invention mainly solves the problems of water outlet and water closing inthe process that the telescopic water outlet pile goes from the underground to the ground. The self-control type water outlet valve for the water outlet pile is composed of a water outlet pile cover,a water outlet valve element, a valve element gland and a water seal, and after the water outlet valve element is sleeved with the water seal, an external thread of the water outlet valve element penetrates through a valve element guide hole in the water outlet pile cover from the interior of the water outlet pile cover and is fixedly connected with the valve element gland. The self-control wateroutlet valve for the water outlet pile meets the functional requirements of the telescopic water outlet pile for the water outlet valve, saves a lot of manpower and material resources for agriculturalproduction, and is reliable in performance, advanced in process and convenient to manufacture.

Description

technical field

[0001] The invention relates to the technical field of agricultural irrigation, and relates to a self-control water outlet valve. Background technique

[0002] Today, in the modern agricultural production in perennially dry and water-scarce areas, the farmland irrigation system that solves the problem of water use for crops is very important. Water outlet piles are widely used in farmland irrigation systems, but there are two problems with the currently used water outlet piles:

[0003] 1. When using large-scale agricultural machinery for farming operations, it is necessary to remove the water outlet pile, which consumes a lot of manpower and material resources. It is also necessary to block the water outlets of the pipe network with plugs, and the removed water outlet piles must be kept;

[0004] 2. When the irrigation system needs to be used, it is necessary to spend time to find the distribution points of the water outlet piles. After finding them, it is n...
