A patch-type drip tape in combination with the examples shown in fig. 1-10, comprising: the delivery tube 100 and the water blocking patch 10 are shown with only one water blocking patch 10, and in practice, a plurality of water blocking patches 10 are uniformly spaced along the length direction of the delivery tube 100, and the water blocking patches 10 are fixed to the inner wall of the delivery tube 100.
As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the water blocking patch 10 includes a substrate 1 and a sealing cover 2 which are mutually attached and fixed, the bottom surface of the substrate 1 is attached to the inner wall of a conveying pipe 100, a water inlet channel 101 is provided at a first end of the substrate 1, a water outlet hole 102 is provided at a second end of the substrate 1, a water blocking flow channel 103 for decompressing water flow is provided between the water inlet channel 101 and the water outlet hole 102, two ends of the water blocking flow channel 103 are respectively communicated with the water inlet channel 101 and the water outlet hole 102, and a water dropping hole (not shown in the figure) corresponding to the water outlet hole 102 is provided on the conveying pipe 100.
Thus, the water in the conveying pipe 100 enters through the water inlet channel 101, is decompressed through the water blocking flow channel 103, and is discharged through the water outlet hole 102 and the water dripping hole in sequence, so that the drip irrigation of crops is performed.
In order to reduce pressure and reduce speed of water, the length of the pressure reducing flow passage in the patch is longer, the cross section of the pressure reducing flow passage is smaller, impurities in water easily block the pressure reducing flow passage in the using process, a water outlet cannot be used for drip irrigation, the section of pipeline is damaged, and the patch type drip irrigation belt is formed by continuous extrusion and is difficult to maintain.
As shown in fig. 2 and 3, the filter screen 3 is fixed at the inlet of the water inlet channel 101, and is used for filtering water entering the base plate 1, so as to prevent impurities in the water from entering, and effectively prevent the water blocking flow channel 103 from being blocked.
Further, a diaphragm 4 is arranged in the water inlet channel 101, a water passing hole 104 corresponding to the diaphragm 4 is formed in the bottom surface of the water inlet channel 101, a pressure relief part 5 for relieving pressure is arranged at the bottom of the water passing hole 104, and the pressure relief part 5 is in a closed state when the water pressure does not meet the pressure relief pressure of the pressure relief part 5.
Thus, when the water pressure in the conveying pipe 100 is normal, the water flow is filtered by the filter screen 3, enters the water inlet channel 101, the membrane 4 is elastically deformed under the action of the water pressure and is bent to the middle position of the water passing hole 104, and the bottom of the water passing hole 104 is sealed and forms a groove because the normal water pressure does not exceed the pressure relief pressure of the pressure relief part 5, the water flow can pass through the membrane 4 through the water passing hole 104, then flows through the water blocking flow channel 103 for pressure reduction, is discharged through the water outlet hole 102 and the corresponding water dripping hole on the conveying pipe 100, and is subjected to drip irrigation;
when no water pressure is transmitted in the conveying pipe 100, the diaphragm 4 resets under the action of self elasticity, so that water in the water inlet channel 101 is pushed to one side of the filter screen 3 by the diaphragm 4, the filter screen 3 is backwashed, impurities attached to the outer side of the filter screen 3 are washed away, and the phenomenon that the impurities on the filter screen 3 are accumulated for a long time to cause blockage is avoided.
Through setting up filter screen 3 at water inlet channel 101, to the water filtration that gets into in base plate 1, avoid blocking up the runner 103 that blocks water, simultaneously, when cutting off water, utilize diaphragm 4 elasticity restoring force, promote the water in the water inlet channel 101 to flow to filter screen 3, back flush to filter screen 3, avoid filter screen 3 to be attached to impurity pile up the jam to keep blocking up the smoothness of paster 10, improve drip irrigation zone's whole life.
Because the drip irrigation belt is paved in a farmland for use, planting devices in the farmland can possibly press the drip irrigation belt, so that the drip irrigation belt is not circulated, the water pressure in a pipeline at the upstream of the pressing part is increased, and the drip irrigation belt is broken due to overlarge pressure.
Referring to fig. 4, when the delivery water pressure in the delivery pipe 100 is too high, the membrane 4 is bent under the action of the water pressure to completely cross the water passing hole 104, at this time, the water in the substrate 1 does not flow to the water blocking flow channel 103, after the water pressure in the water inlet channel 101 reaches the pressure relief pressure of the pressure relief component 5, the pressure relief component 5 is opened, and the delivery pipe 100 is provided with a pressure relief hole (not shown in the figure) corresponding to the water passing hole 104, and when the pressure relief component 5 is opened, the water is discharged and relieved through the water passing hole 104 and the pressure relief hole on the delivery pipe 100, so that the delivery pipe 100 is prevented from bursting due to the too high pressure.

Thus, when the pressure does not reach the pressure of the pressure relief, the four sheets are mutually attached to seal the bottom of the water passing hole 104, and when the pressure reaches the pressure relief pressure, the elastic membrane 51 opens the pressure relief along the notch.
Further, the elastic membrane 51 is formed in a dome shape, and the center of the elastic membrane 51 protrudes toward the inside of the water passing hole 104, and in the case where the thickness is constant, the water pressure that the elastic membrane 51 can withstand can be increased by this shape, and the thickness of the elastic membrane 51 can be reduced.
Optionally, the elastic film 51 is made of polypropylene.
In another alternative embodiment, as shown in fig. 7 and 8, the pressure release component 5 includes a sealing plug 52 and a spring 53, where the sealing plug 52 is located at the bottom of the water hole 104 and is used for sealing the bottom of the water hole 104, the top end of the spring 53 is fixed in the water hole 104, and the bottom end of the spring 53 is fixedly connected with the sealing plug 52.

Thus, when the pressure does not reach the pressure relief pressure, the movable end cover of the elastic sheet 54 is arranged at the bottom of the water passing hole 104 to seal the bottom of the water passing hole 104, and when the pressure reaches the pressure relief pressure, the movable end of the elastic sheet 54 swings downwards and relieves the pressure.
As shown in fig. 2, 3 and 4, the water inlet channel 101 is horn-shaped, the narrowing end of the water inlet channel 101 faces the filter screen 3, the membrane 4 is located at the amplifying end of the water inlet channel 101, when the membrane 4 is elastically restored, water at the amplifying end of the water inlet channel 101 is pushed to the narrowing end, the water pressure for flushing the filter screen 3 is increased, and impurities attached to the filter screen 3 are flushed and fall off better.
