Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a prevent outer hourglass self sealss valve, solenoid valve 2 is provided with two altogether, and two 2 symmetries of solenoid valve set up on the outer wall of valve body 1, can realize the sealed at 1 both ends of valve body, and then cut off the liquid source, avoid liquid to last the problem of leaking outward.

The valve body 1 and the connecting pipe 3 are both communicated with the electromagnetic valve 2, so that the flowing circulation of liquid is ensured.

And a bolt mounting hole is formed in the outer wall of one side of the flange plate 4, so that the flange plate 4 and an external water pipe can be conveniently connected and communicated.

The cross section of the supporting rod 6 is of an L-shaped structure, so that the detection block 8 can be arranged below the flange plate 4 conveniently.

One end of the drain plug 12 penetrates through the rubber pad 9, one end of the drain plug 12 is located inside the detection cavity 10, and the deformation capacity of the rubber pad 9 can wrap the flange plate 4 through the rubber pad 9, so that liquid seeped between the flange plate 4 can be collected and detected, and the effect of leakage outside the detection is achieved.

The flange plate 4 is fixedly connected with the water pipe 5 through bolts, so that the flange plate 4 is tightly and firmly connected with the water pipe 5.

The electromagnetic valve 2, the liquid level sensor 11 and the storage battery 15 are all electrically connected with the controller 14, and the controller 14 can control the electromagnetic valve 2 to be opened and closed, so that the liquid flowing source is blocked, and the effect of preventing leakage is achieved.

The working principle is as follows: when the liquid leakage detection device is used, the flange plates 4 on the connecting pipes 3 are fixedly installed together with the water pipes 5 through bolts, the two flange plates 4 are installed together in a butt joint mode, the screw rod 7 is rotated, one end of the screw rod 7 drives the detection block 8 to ascend and descend in the vertical direction, the detection block 8 is held, the detection cavity 10 in the rubber pad 9 is aligned to a gap between the two flange plates 4, the screw rod 7 is continuously rotated, the screw rod 7 pushes and extrudes the detection block 8 and the rubber pad 9, the rubber pad 9 is wrapped outside the two flange plates 4 after being deformed, when leakage occurs at the joint of the two flange plates 4, liquid flows out along the gap between the two flange plates 4 and flows into the detection cavity 10, when liquid in the detection cavity 10 reaches a certain depth, the liquid level sensor 11 transmits information to the controller 14 after detecting the liquid information, the controller 14 controls the electromagnetic valve 2 to be closed, the valve body 1 is closed through the electromagnetic valve 2, the flowing circulation of the liquid can be avoided, the problem that the liquid continuously leaks from the joint of the flange plates 4 is avoided, and the valve body 1 is closed when leakage occurs.

In summary, the following steps: this prevent outer hourglass self sealss valve warp the parcel on ring flange 4 through rubber pad 9, not only reduces the influence of outside rainwater, can also collect and detect the liquid that oozes between ring flange 4 under the collection effect that detects chamber 10, reaches the effect that detects outer hourglass, closes valve body 1 through solenoid valve 2, can avoid the liquid flow circulation, from avoiding the ring flange 4 junction to last the problem of outer hourglass sepage, from sealing when realizing that valve body 1 leaks outward.
