Generally, the height of the horizontal plate 18 cannot be too high or too low, which is not favorable for releasing water in the water storage tank 2, and too low water has insufficient impact force, which results in insufficient supporting force and cannot release water flow in the water storage tank 2.
The bottom of the water outlet groove 23 is provided with an emptying valve 17. Because the horizontal plate 18 is arranged, water in the water storage tank 2 cannot be completely released, and the water in the equipment can be drained by using the drain valve 17 after irrigation is completed.
The water storage tank 2 is provided with water depth scale marks. The depth of water is directly proportional with the pressure that pressure plate 8 received, can be through setting up the depth of water scale mark, according to the relation of depth of water and pressure, the convenient regulation supporting spring 10's radical, and then the adjustment irrigation parameter, and is simple and convenient.
The operation process of the intermittent large-flow farmland irrigation valve comprises the following steps:
the number of the supporting springs 10 is determined according to required irrigation parameters, then equipment is connected, in the water storage stage, the locking columns 14 penetrate through the locking holes 25 under the action of the supporting springs 10 to be in close contact with the sealing plates 13, the sealing plates 13 are fixed to be in a sealing state, the supporting rods 16 push against the locking columns 14, and fixing stability is improved. Water enters the water storage tank 2 through the water inlet 1, the pressure plate 8 moves downwards under the pressure of the water, the supporting plate 22 is further driven to move downwards, and the supporting plate 22 drives the locking column 14 to move downwards. Along with the increase of the water depth, the locking column 14 is separated from the locking hole 25, the sealing plate 13 moves upwards under the action of the pressure of water, meanwhile, the support rod 16 moves downwards under the action of the impact force of the water and the gravity of the counterweight ball 19 to stand the support rod 16 to support the sealing plate 13, the water in the water storage tank 2 flows out quickly from the water outlet groove 23, the impact force of the water flow is reduced along with the reduction of the water flow, when the height of the water flow is consistent with that of the horizontal plate 18, the support force of the support rod 16 is reduced, and under the action of the gravity of the sealing plate 13, the sealing plate 13 moves downwards to drive the support rod 16 to move upwards, so that the locking column 14 passes through the locking hole 25, the sealing plate 13 is fixed, and the support rod 16 tightly supports the locking column 14 to complete one-time irrigation operation. The above process is repeated to finish irrigation, and then the emptying valve 17 is opened to empty the water in the water storage tank 2.
