[0013] By adopting the above technical solution, controlling the opening of the butterfly valve can control the flow of the drain water into the drain water confluence well, ensuring that the drain water can eventually enter the rainwater system for discharge at an appropriate flow rate.

[0014] Furthermore, the water inlet of the drain water confluence well is lower than the drain water confluence well's outlet.

[0015] By adopting the above technical solution, the drained water confluence well can release the pressure of the discharged pressurized water to form a free water surface.

[0020] Furthermore, the corresponding open flow connecting pipe extends into the drainage inspection well and the rainwater inspection well through the well wall casing.

[0021] By adopting the above technical solution, the water flowing through the drainage inspection well can be conveniently discharged into the existing rainwater system under the action of the corresponding open flow connecting pipe.

[0022] Furthermore, the drainage inspection well and the completed rainwater inspection well belong to the same type of inspection wells, the open flow connecting pipe has the same diameter as the completed factory area rainwater pipe, and the open flow connecting pipe matches the flow capacity of the rainwater inspection well.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] like Figure 1-Figure 2As shown, the pool safety discharge device under the control of the flow control valve well in this embodiment includes a safety discharge system 2 and an established rainwater system 1. The safety discharge system 2 includes a pressure relief pipe 201 connected to the drainage outlet of the plant pool. The drainage outlet of the pressure relief pipe 201 is connected to the flow control valve well 203 through a connecting steel pipe 202. A butterfly valve 204 is installed on the connecting steel pipe 202 in the flow control valve well 203. A drain water confluence well 205 is arranged on the drainage side of the flow control valve well 203. The opening of the butterfly valve 204 can be controlled to control the drain water entering the drain water confluence well. The flow rate in the drainage well 205 ensures that the final drain water can be discharged at an appropriate flow rate. The drain water confluence well 205 can release the pressure of the pressurized water discharged to form a free water surface lower than the top elevation of the open flow connecting pipe 206. When the drain water is emptied, the remaining water in the drain water confluence well 205 can be discharged with the help of a submersible pump. A drainage inspection well 207 is arranged on the drainage side of the drain water confluence well 205. The open flow connecting pipe 206 is installed at the water inlet and outlet of the drain water inspection well 207. The open flow connecting pipe 206 is mainly used to guide the water in the drain water inspection well 207.

[0032] like Figure 1-Figure 2 As shown, in this embodiment, the completed rainwater system 1 includes a factory rainwater pipe 101 and a rainwater inspection well 102 installed at the confluence of the factory rainwater pipe 101.

The drainage outlet of the pressure relief pipe 201 and the water inlet of the connecting steel pipe 202 are a reduced diameter structure. This design can reduce the diameter of the butterfly valve, facilitate the adjustment of the opening to control the outflow, and reduce the investment in valve components.

[0034] like Figure 1-Figure 2As shown, in this embodiment, the corresponding open flow connecting pipe 206 is extended into the drain water confluence well 205 and the drain water inspection well 207 through the well wall penetration casing. With the help of the open flow connecting pipe 206, the discharged water can be conveniently guided between the drain water confluence well 205 and the drain water inspection well 207. The corresponding open flow connecting pipe 206 is extended into the drain water inspection well 207 and the rainwater inspection well 102 through the well wall penetration casing. Under the action of the corresponding open flow connecting pipe 206, the water flowing through the drain water inspection well 207 can be conveniently discharged into the existing rainwater system 1.

[0035] The specific implementation process of this embodiment is as follows: when it is necessary to discharge the water in the factory pool to facilitate the inspection and maintenance of the inside of the factory pool, first connect the safety discharge system 2 to the factory pool drain outlet and the rainwater system 1, and then the water in the factory pool can be discharged. When the empty water is discharged, the opening of the butterfly valve 204 in the flow state conversion control valve well is adjusted to control the empty water to enter the empty water confluence well 205. At the same time, the open flow connecting pipe 206 installed behind the empty water confluence well 205 is cooperated to form a free water surface in the well that is lower than the top elevation of the open flow connecting pipe 206 to ensure that the water output of the confluence well matches the flow capacity of the open flow rainwater pipe of the established rainwater system 1 at the access point. Under such an emptying and drainage method, the conditions of the different frequencies of the emptying of the pool and the rainwater system are utilized to effectively ensure the safe discharge of the emptying water of the factory pool, realize the coordinated management of the safety discharge system 2 and the rainwater system 1, and embody the concept of water saving.
