In the description of the present utility model, unless otherwise specified, "multiple" means more than two.

[0023] In one embodiment of the present invention, Figure 1-3As shown, a drip valve comprises a valve body 1 and a small ball 2, wherein a water inlet chamber 11 and a water outlet chamber 12 are provided inside the valve body 1, a first joint 111 is provided at one end of the water inlet chamber 11, a water inlet 112 is provided at the other end of the water inlet chamber 11, the water inlet chamber 11 is connected to one end of the water outlet chamber 12 through the water inlet 112, and a water outlet 121 is provided at the other end of the water outlet chamber 12; the small ball 2 is provided inside the water inlet chamber 11, and the small ball 2 can be blocked at the water inlet 112. In this embodiment, the water inlet chamber 11 is provided on the right side of the valve body 1, the first joint 111 is provided on the right side of the water inlet chamber 11, the water inlet 112 is provided on the left side of the water inlet chamber 11, the water outlet chamber 12 is located on the left side of the water inlet chamber 11, and the water outlet 121 is provided at the bottom of the water outlet chamber 12. The drip valve is specifically installed on the sprinkler valve, and the first joint 111 is connected to the sprinkler valve through a water pipe. If the sprinkler valve leaks when it is not working, the leaked water enters the water inlet chamber 11 from the first joint 111 through the water pipe. Because the water flow rate generated by the leakage is small, the leaked water cannot push the small ball to block the water inlet 112, and then the leaked water enters the water outlet chamber 12 from the water inlet 112 of the water inlet chamber 11, and then flows out from the water outlet chamber 12. The water is discharged from the water outlet 121. If water continues to drip for a long time, the drip valve will serve as a warning, proving that the sprinkler valve is leaking. If the sprinkler valve is working normally, the water in the sprinkler valve will still enter the water inlet chamber 11 from the first joint 111 through the water pipe, and the water flow rate is large at this time, so the water will push the ball 2 to the water inlet 112, so that the ball 2 blocks the water inlet 112. At this time, the ball 2 plays a sealing role to ensure the normal operation of the sprinkler valve. The present application uses the valve body 1, the water inlet chamber 11, the first joint 111, the water inlet 112, the water outlet chamber 12, the water outlet 121 and the ball 2 to determine whether the sprinkler valve is leaking while ensuring the normal operation of the sprinkler valve, so that maintenance and repair can be carried out in time, thereby achieving the effect of improving the working stability and reliability of the sprinkler valve.

[0024] like Figure 1 As shown, it also includes a push-out assembly 3, which is installed on the valve body 1, and the end of the push-out assembly 3 can be against the ball 2. In this embodiment, when the ball 2 is blocked in the water inlet 112, in order to facilitate its escape from the water outlet 112, the push-out assembly 3 can be used to push the ball 2 out of the water inlet 112, which not only facilitates the escape and reset of the ball 2, but also prevents the ball 2 from being stuck and unable to be reset.

[0025] like Figure 1-2As shown, the push assembly 3 includes a pressing member 31, a push rod 32 and a spring 33; the push rod 32 can be installed on the valve body 1 so as to be movable left and right, the pressing member 31 is installed on the left end of the push rod 32, the spring 33 is installed on the outer periphery of the push rod 32, one end of the spring 33 abuts against the pressing member 31, and the other end of the spring 33 abuts against the valve body 1. In this embodiment, when it is necessary to push the ball 2, the push rod 32 is moved to the right by pressing the pressing member 31, at which time the spring 33 is in a compressed state, so that the right end of the push rod 32 pushes the ball 2 out of the water inlet 112, and then the pressing member 31 is released. Under the action of the spring 33, the spring 33 pushes the pressing member 31 to the left to reset, so that the push rod 32 is reset to the left, which is convenient and quick.

[0026] like Figure 1-2 As shown, the valve body 1 further includes a second joint 4, which is detachably mounted on the left side of the valve body 1, the push rod 32 is slidably mounted on the second joint 4, one end of the spring 33 abuts against the pressing member 41, and the other end of the spring 33 abuts against the second joint 4. In this embodiment, the second joint 4 is detachably mounted on the left side of the valve body 1 through a threaded connection, and when the pushing assembly 3 is removed to replace parts or for maintenance, it is only necessary to remove the second joint 4 from the valve body 1, which is convenient and quick.

[0027] like Figure 3 As shown, the push rod 32 includes a mounting section 321, a sliding section 322, a limit block 323 and a pushing section 324; the right end of the mounting section 321 is connected to the sliding section 322, the mounting section 321 is installed with the pressing member 31, the right end of the sliding section 322 is connected to the left side of the limit block 323, the sliding section 322 can be slidably installed on the second joint 4, the left end of the pushing section 324 is connected to the right side of the limit block 323, the limit block 323 is located in the water outlet cavity 12, and the left side of the limit block 323 can be against the right end surface of the second joint 4. In this embodiment, the mounting section 321, the sliding section 322, the limit block 323 and the pushing section 324 are connected in sequence, the mounting section 321 is installed with the pressing piece 31, the sliding section 322 is slidably installed on the second joint 4, and the spring 33 is sleeved on the outer periphery of the sliding section 322, one end of the spring 33 abuts against the pressing piece 31, and the other end of the spring 33 abuts against the second joint 4, and the limit block 323 can move left and right in the water outlet chamber 12. When resetting, the left side of the limit block 323 abuts against the right end face of the second joint 4, and the limit block 323 plays a limiting blocking role, thereby preventing the push rod 32 from escaping from the valve body 1, and the pushing section 324 is used to push out the ball 2.

[0028] like Figure 3 As shown, the mounting section 321 is provided with a locking groove 3211, and the pressing member 31 is provided with a locking hole 311, and the locking hole 311 can be directly opposite to the locking groove 3211. In this embodiment, when the pressing member 31 is mounted on the push rod 32, specifically, the mounting section 321 is placed inside the pressing member 31, and the locking groove 3211 is directly opposite to the locking hole 311, and then the locking member is extended from the locking hole 311 and the end of the locking member is placed in the locking groove 3211, so that the push rod 32 cannot be disengaged from the pressing member 31, and the installation is convenient and quick.

[0029] like Figure 1 As shown, the ball 2 is made of rubber. In this embodiment, the ball 2 is a rubber ball because the rubber material has good elasticity and resilience, can be well blocked in the water outlet 112, thereby improving its sealing performance, and has good wear resistance, anti-skid, corrosion resistance and insulation properties.
