DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0021] like Figures 1 to 4The emergency water shut-off valve for fishery microfiltration equipment shown is characterized in that it includes: a breeding pond 1, a microfiltration equipment 2 is arranged on one side of the breeding pond 1, an outlet pipe 3 is connected to the bottom of the rear side of the breeding pond 1, an input pipe 4 is connected to the rear side of the microfiltration equipment 2, a connecting pipe 5 is connected between the outlet pipe 3 and the input pipe 4, the middle part of the connecting pipe 5 is an inverted U-shape extending upward, the extension pipe 6 is connected and arranged on the left side of the extension of the connecting pipe 5, an extension pipe 6 is connected to the connecting pipe 5, a valve body 7 is arranged in the extension pipe 6, a fixing frame 8 is provided on the front side of the connecting pipe 5, and a driving valve part 9 is fixed above the fixing frame 8.

[0022] The above structure is an emergency water shut-off valve for fishery microfiltration equipment. During daily use, the valve portion 9 is driven to lock the valve body 7, so that the valve body 7 is in the extension pipe 6. The water in the breeding pond 1 is transported to the connecting pipe 5 through the outlet pipe 3. At the same time, the connecting pipe 5 transports the water to the microfiltration equipment 2 through the input pipe 4. The microfiltration equipment 2 filters the water and then returns it to the breeding pond 1. When the power is off, the valve portion 9 is driven to unlock the valve body 4, so that the valve body 4 moves downward along the extension pipe 6. At this time, the water in the connecting pipe 5 impacts the valve body 7 toward the connecting pipe 5, so that the valve body 4 closes the connecting pipe 5, and the water cannot flow from the breeding pond 1 to the microfiltration equipment 2. Compared with the prior art, the water in the breeding pond can be urgently shut off in time to prevent the water in the breeding pond from being drained, thereby reducing losses caused by the fishery.

[0023] like Figure 3 As shown, in some embodiments of the present invention, the valve body 7 includes a column 71 movably inserted in the extension tube 6, a plurality of through grooves 72 are arranged at intervals on the surface of the column 71, a plug rod 73 is fixedly arranged above the column 71, a cover body 74 is sealed and covered above the extension tube 6, a through hole 75 is arranged in the middle of the cover body 74, the plug rod 73 is movably inserted in the through hole 75, and a baffle 76 is fixed at the upper end of the plug rod 73. When the driving valve part 9 is powered off and the plug rod 73 is unlocked, the column 71 drives the plug rod 73 to move downward along the through hole 75, so that the column 71 moves toward the extension of the connecting pipe 5. At this time, the water in the connecting pipe 5 flows into the through groove 72, and at the same time, the column 71 moves downward along the extension of the connecting pipe 5 through the through groove 72. When the plug rod 73 moves to the specified position, its moving distance is limited by the baffle 76. When the power is turned on, the user pulls the baffle 76 upward, so that the plug rod drives the column 71 to move to the position of the raw material.

[0024] like Figure 3As shown, in some embodiments of the utility model, the driving valve portion 9 includes an annular groove 91 arranged on the surface of the plug-in rod 73, a solenoid valve 92 is fixedly provided above the fixing frame 8, a block 93 is fixed at the output end of the solenoid valve 92, and a fixing bolt 931 is fixed at the end of the block 93, the fixing bolt is fixedly connected to the output end of the solenoid valve 92, and an arc groove 94 is provided on the block 93. When the power is off, the output end of the solenoid valve 92 shrinks, so that the block 93 fixed at its output end shrinks. At this time, the arc groove 94 on the block 93 is separated from the annular groove 91 on the surface of the plug-in rod 73, and the block 93 is fixedly installed at the output end of the solenoid valve 92 by the fixing bolt 931.

[0025] like Figure 1 As shown, in some embodiments of the present invention, drain pipes 51 are provided extending and communicating on both the left and right sides of the connecting pipe 5 .

[0026] It should be noted that a first closing valve 52 is provided on the right side of the connecting pipe 5 and one of the drain pipes 51, and a second closing valve 53 is provided on the left side of the connecting pipe 5 and the other drain pipe 51. By closing one of the first closing valves 52, the drain pipe 51 on the right side can discharge the water in the breeding pond 1 to prevent the water in the breeding pond 1 from overflowing. When the other first closing valve 52 is closed, the delivery of the outlet pipe 3 and the connecting pipe 5 can be cut off. When the user closes one of the second closing valves 53, the drain pipe 51 on the left side can drain the water in the connecting pipe 5 to prevent the connecting pipe 5 from being damaged by excessive water pressure in the connecting pipe 5. When the user closes the other second closing valve 53, the input pipe 4 and the connecting pipe 5 can be cut off.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model.
