Detailed Description

The following describes specific embodiments of the present invention with reference to the drawings.

Referring to fig. 1 to 3, a watering system for a vegetable greenhouse capable of regulating and distributing water according to water pressure comprises a greenhouse 1 and a water tower 2. Roof-rack is equipped with a flow pipe 23 in big-arch shelter 1, and flow pipe 23 is connected with the delivery port of water tower 2, and interval arrangement has a plurality of groups pressure shower nozzle 3 on the flow pipe 23, and every group pressure shower nozzle 3 is a set of three, and three pressure shower nozzle 3 spray the direction diverse, spray for the left side respectively, the right side sprays and spray in the middle of. The pressure nozzle 3 comprises a nozzle body 31, a water inlet 32 and a water outlet panel 33 are respectively arranged on the nozzle body 31, a spring top plate 34 is further arranged in the nozzle body 31, the spring end of the spring top plate 34 is fixedly connected to the water outlet panel 33, and the top plate end of the spring top plate 34 is supported on the water inlet 32 in a seamless mode.

Referring to fig. 2, 4 and 5, the water seepage pipe 4 is buried in the soil in the greenhouse 1, and a plurality of water seepage holes are arranged on the water seepage pipe 4. The water supply pipe 23 is connected to the water seepage pipe 4 through a pressure shunt valve 5 which can shunt water according to the water pressure. The pressure water distribution valve 5 comprises a valve body 51, a first water inlet 52 and a first water outlet 53, the first water inlet 52 is communicated with the water supply pipe 23, the first water outlet 53 is communicated with the water seepage pipe 4, the first water inlet 52 is connected with an annular baffle plate 54 through threads, a notch 57 for conveniently rotating the annular baffle plate 54 is formed in the inner side wall of the annular baffle plate 54, a pressure spring 56 is arranged at the bottom of the valve body 51, the pressure spring penetrates through the annular baffle plate 56 to be connected with a movable top plate 55, and the movable top plate 55 can be seamlessly supported and covered on the annular baffle plate 54. In the initial state, the movable top plate 55 is kept at a certain distance from the annular baffle 54 under the propping of the pressure spring 56.
