[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Example 1

[0020] See also Figure 1-4 : A valve well space anti-water storage leakage detection monitoring device includes a sealing cover body 1 installed in the valve well space, and an accommodating space 101 is provided at the upper end of the sealing cover body 1, and the accommodating space 101 is used to install a monitoring sensor.

[0021] The device of this embodiment is simple, direct and efficient to operate. The staff can easily place the device in the predetermined target valve well to achieve easy and advance drainage. It ensures that the valve well with habitual water accumulation will not accumulate water for a long time, which is convenient for maintenance and control operation. In addition, the valve well can be monitored by monitoring sensors to prevent problems before they occur.

[0022] In a specific example, a high-leakage and low-sealing valve 2 is further provided in the accommodating space 101 .

[0023] This embodiment fully considers the possibility of slight leakage in the pipe section in the valve well area and the valve itself. The top of the device is designed with a corresponding "high-leakage and low-sealing valve" to safely relieve pressure and ensure that the pressure in the internal space never exceeds the established pressure setting value.

[0024] In a specific example, the high-leakage and low-sealing valve 2 includes a valve body, on which a pressure-stabilizing and pressure-relief sampling port 201, a conduction rod 202, and two sets of sealing disc hand-pull springs 203 are installed from top to bottom. The two sets of sealing disc hand-pull springs 203 are sealed by a sealing disc 204 and a sealing ring 205. The lower sealing disc hand-pull spring 203 is fixed to the upper end of the sealing cover 1 through a pressure-relief fastening nut 206 and is connected.

[0025] In this embodiment, when the pressure of the sealing cover body increases, the sealing disk of the high-leakage and low-sealing valve and the sealing disk hand-pull spring rise synchronously, and air is released through the gap between the valve body and the valve body to reduce the pressure value, thereby ensuring that the pressure in the internal space never exceeds the established pressure setting value.

[0026] In a specific example, the sealing disc 204 and the sealing ring 205 are supported and placed inside the valve body 201 by a sealing extrusion support 207 .

[0027] The sealing extrusion support of this embodiment can provide supporting force for the sealing disk and the sealing ring. Due to the tension of the spring, when the internal pressure is at a normal value, the sealing disk and the sealing ring form an abutting seal with the sealing extrusion support due to the action of the spring. When the pressure value increases, the sealing disk and the sealing ring are lifted to create a gap, thereby safely relieving the pressure. When the pressure value is normal, the seal falls back due to the action of the spring, thereby achieving low-pressure sealing.

[0028] In a specific example, the monitoring sensors are a pressure sensor 3 and a gas medium identification sensor 4 based on the NB-iot cellular network.

[0029] This embodiment uses pressure and gas medium analysis related sensing and remote transmission devices based on the NB-iot cellular network to grasp the leakage situation of the valve well and surrounding locations.

[0030] In a specific example, an anti-blocking groove 102 is further provided on the outer side wall of the sealing cover 1 .

[0031] This embodiment also takes into account the possibility of individual obstructions on the well wall, and therefore, an anti-obstruction groove is provided on the side of the device.

[0032] In a specific example, a plug-in portion 103 is provided at the lower portion of the sealing cover 1 .

[0033] The plug-in portion of this embodiment can be directly inserted into the sand filling in the valve well, and therefore, to a certain extent, can be applied to valve wells of different depths.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
