Technical Field
The utility model belongs to the technical field of the agricultural instrument for driping irrigation, in particular to drip irrigation system ground branch pipe pressure measurement pressure regulating connecting device.
Background
At present, in the drip irrigation process of crops such as fruit trees, cotton and the like, the pressure of a ground branch pipe close to a water pump is high, the pressure of a ground branch pipe far away from the water pump is low, a plot with high pressure is changed from 'watering crops' into 'watering lands', and the value of drip irrigation is lost; the plots with small pressure have insufficient supply of fertilizer and water, which affects the growth of crops. Farmers often adjust the pressure of the ground pipeline by the feeling of human, but the effect is poor and is contrary to the concept of 'precise fertilization and precise irrigation' advocated at present. If pressure measurement and pressure regulation are performed through a direct pressure gauge on a ground pipeline, water leakage at a connecting part and incapability of filtering impurities and damaging the pressure gauge are often caused, so that the pressure measurement is inaccurate, and the pressure regulation of the pipeline cannot be guided.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a connecting device of joinable ground branch pipe, air-vent valve, manometer, but lug connection in buried pipe delivery port also can connect in the ground pipe water diversion mouth. The pressure of the whole drip irrigation system is adjusted by measuring the pressure of the water diversion port and combining with a pressure regulating valve, so that the irrigation and fertilization are uniform and consistent, and the aim of drip irrigation of the root zone of the crops is fulfilled.
The purpose of the utility model is realized through following technical means: a pressure measuring and regulating connecting device for a ground branch pipe of a drip irrigation system comprises a pressure gauge connecting inner screw port, a stop valve connecting inner screw port, a pressure regulating ball valve connecting outer screw port, a ground branch pipe connecting inner screw port and a valve, wherein the connecting device is of a three-way structure; the valve comprises a filter screen, a switch and a stopping lamination, wherein the stopping lamination and the filter screen are perpendicular to each other and are in cross connection at the center, and the switch is connected to one side of the stopping lamination and the filter screen through a baffle.
Preferably, the filter screen is a 200-mesh filter screen.
Has the advantages that:
1. the problem of whole drip irrigation system inconsistent pressure can be effectively solved, and to whole drip irrigation system, the ground branch pipe pressure that is close to the water pump is big, and the ground branch pipe pressure of keeping away from the water pump is little, and the artificial sensation of relying on is adjusted and can only be reached roughly the effect, influences crop root zone irrigation effect. The utility model discloses a connection device as manometer, pressure regulating ball valve, ground branch pipe can realize accurate pressure measurement, pressure regulating, makes the even unanimity of whole drip irrigation system pressure, on the basis of practicing thrift investment cost, reaches the purpose of accurate drip irrigation.
2. Can effectively solve the problem of being connected of manometer and drip irrigation system PE pipe, pressure regulating ball valve, the utility model discloses a dual-purpose switch of PVC intraductal silk, outer silk and connection manometer connects the manometer on drip irrigation system through three-way mode, and the cooperation air-vent valve can guarantee that branch pipe reposition of redundant personnel can not cause the pressure of other pipelines too big or the undersize at every turn.
3. The utility model discloses a through install dual-purpose switch (filter screen and stop lamination) additional at the manometer junction, when needing the pressure measurement, open the valve switch, make stop lamination and rivers direction be in the horizontal direction, make the filter screen perpendicular to rivers direction; when the pressure is not measured, the valve switch is closed, the stop lamination is perpendicular to the water flow direction, the water flow is cut off, and the pressure gauge is taken away. The pressure of the whole drip irrigation system is effectively controlled to be uniform, and meanwhile, a pressure gauge does not need to be installed at each pressure measuring part, so that the purposes of cost saving and efficiency improvement are achieved.

Detailed Description
The technical scheme of the utility model is described in detail with the accompanying drawings.
As shown in fig. 1, the utility model discloses a pressure measuring and pressure regulating connection device for a ground branch pipe of a drip irrigation system, which comprises a pressure gauge connection internal thread opening 1, a stop valve connection internal thread opening 2, a pressure regulating ball valve connection external thread opening 3, a ground branch pipe connection internal thread opening 1 and a valve 6, wherein the connection device is of a three-way structure, the pressure regulating ball valve connection external thread opening 3 and the ground branch pipe connection internal thread opening 4 are respectively connected with the pressure regulating ball valve and the ground branch pipe, the pressure gauge connection internal thread opening 1 is connected with a pressure gauge, the stop valve connection internal thread opening 2 is connected with the valve, and the pressure gauge connection internal thread opening 1 is connected with a branch pipe of the three-way through the valve 6; the valve 6 is composed of a filter screen 7, a switch and a stopping lamination 5, the stopping lamination 5 and the filter screen 7 are perpendicular to each other and are in cross connection at the center, and the switch is connected to one side of the stopping lamination 5 and one side of the filter screen 7 through a baffle.
