[0009] To achieve the above object, the utility model discloses the centralized arrangement well of gas buried valve, including the well body that is arranged in the underground, and the cross section is rectangular, long circle or oval;

[0010] Two or more gas buried valves are arranged in parallel in the well body along the maximum width direction;

[0011] The inlet and outlet pipes of each gas buried valve are not higher than the cushion layer below the well body;

[0012] The operating cap and the part above each gas buried valve are located above the cushion layer;

[0013] The space between the upper surface of the cushion layer and the operating cap in the well body is filled with fine sand, and the space below the upper surface of the cushion layer is filled with backfill soil.

[0014] Preferably, the pressure monitoring device and the leakage alarm device are arranged in the well body.

[0015] More preferably, the pressure monitoring device and the leakage alarm device upload the collected information to the computer of the monitoring center through wired or wireless mode;

[0016] The computer judges the collected information of the pressure monitoring device and the leakage alarm device according to the preset program, and shows the result, and sends an alarm when any of the buried gas valves leaks.

[0017] Preferably, the well cover arranged at the well mouth of the well body is rectangular, oblong or elliptical matching the cross section of the well body.

[0018] The utility model discloses the beneficial effects:

[0019] The utility model discloses the space layout in the valve well is optimized, reduces the land occupation of valve well, solves the problem of land blockage and pipe position tension encountered in the layout of buried gas valve.

[0020] The utility model discloses the space is more concentrated, and the valve of multiple same pressure level is combined to the same well body, which can reduce the number of valve wells by more than 50%, greatly increasing the land utilization rate.

[0021] The utility model reduces the construction cost of valve well, shortens the construction period, relieves the contradiction of underground pipe position, improves the urban space utilization rate, reduces the ground facility density, optimizes the urban landscape, is applicable to the scene such as city complex, subway upper cover property, and has remarkable economic and social benefits.

[0022] The utility model is more safe and reliable, realizes the remote monitoring of valve state through the setting pressure monitoring device and leakage alarm system and the internet of things platform, and guarantees valve repair operation and daily operation safety.

[0023] The utility model can make the setting area landscape of buried gas valve more friendly, and reduce the adverse effect on the surrounding landscape.

[0024] The concept, specific structure and generated technical effects of the utility model will be further described in combination with the drawings, so that the novel purpose, structural features and operation and maintenance effects of the utility model can be fully understood.
