[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figures 1-2 As shown;

[0023] An integrated wet automatic sprinkler system control valve assembly, comprising an electric butterfly valve 1, a groove check valve 2 and a groove steel pipe 5 connected in sequence along the water flow direction;

[0024] The groove check valve 2 and the groove steel pipe 5 are connected through a pipe clamp 3, the groove steel pipe 5 is provided with a water flow indicator 4, the outer wall of the end of the groove steel pipe 5 is communicated with a steel pipe 11, and the end of the steel pipe 11 is communicated with a pressure gauge 9 through a pressure gauge valve 10;

[0025] A reducing tee 6 is arranged between the water flow indicator 4 and the pressure gauge 9, the reducing tee 6 is communicated with the groove steel pipe 5, and the lower end of the reducing tee 6 is communicated with a drain valve 8 through a butt joint wire head 7.

[0026] In the embodiment, when the system is normally operated, the system pipe network is full of water with working pressure, the system side pressure is equal to the water supply side pressure, at this time, the groove check valve 2 and the drain valve 8 are both in the closed state, the water flow indicator 4 does not act, and the pressure gauge 9 displays the non-normal working pressure;

[0027] When the system side uses water, the system side pressure decreases, under the action of the pressure difference, the system main valve flap opens, the water on the water supply side flows into the system side, the water flow indicator 4 acts to send an alarm signal, so that the system starts to work and is in the water spraying state;

[0028] When the water supply pressure of the water supply side is weakened and the water supply pressure is less than the system pressure, the groove check valve 2 prevents the water in the system side from flowing back, prevents the water supply side from being damaged to the equipment and polluting the water system due to backflow;

[0029] It should be noted that in the embodiment, the pressure gauge 9 is used to indicate the system side pressure, and the drain valve 8 is used for system testing and emptying residual water.

[0030] In an alternative embodiment, the control valve assembly is installed into the system at the water flow inlet of the spray main pipe and is connected through grooves.

[0031] In the embodiment, the control valve assembly is used to automatically adjust the system, realizes the functions of dynamic management, remote control and anti-backflow, is integratedly designed, achieves the effect of multifunction, and is simple to install.

[0032] In an alternative embodiment, the electric butterfly valve 1 is controlled by the system to cut off the water source after extinguishing the fire or during system maintenance.

[0033] In the embodiment, it is convenient to make corresponding operations according to the needs of the system.

[0034] In an alternative embodiment, the water flow indicator 4 is used to transmit the signal when the system pipe network main valve is opened to the control room to display the fire occurrence area.

[0035] In this embodiment, it is convenient for the personnel of the controller to determine the fire location in time so as to carry out corresponding rescue work according to the fire location.

[0036] The working principle and use process of the utility model are as follows: the control valve assembly is installed into the water inlet of the sprinkler main pipe and connected to the system with a groove;

[0037] When the system is operating normally, the system pipe network is filled with water at working pressure, and the pressure on the system side is equal to the pressure on the water supply side. At this time, the groove check valve 2 and the drain valve 8 are both in the closed state, the water flow indicator 4 on the grooved steel pipe 5 does not operate, and the pressure gauge 9 on the steel pipe 11 shows abnormal working pressure;

[0038] When water is added to the system side, the pressure on the system side drops. Under the action of the pressure difference, the main valve flap of the system opens, and water from the water supply side flows into the system side. The water flow indicator 4 is activated, and an alarm signal is issued, so that the system starts working and is in the water spraying state. The electric butterfly valve 1 is controlled by the system to cut off the water source after fire extinguishing or during system maintenance.

[0039] When the water supply pressure on the water supply side weakens and is lower than the system pressure, the groove check valve 2 prevents water from flowing back from the system side, thereby preventing the water supply side from causing damage to the equipment and pollution to the water system due to backflow;

[0040] The integrated product composed of various standard parts can be seamlessly integrated with existing control systems or automation equipment to form an integrated design, which is convenient and quick to install and maintain, reducing maintenance costs. It can automatically open or close valves according to system needs to achieve the purpose of automatic adjustment, avoiding damage to equipment in the system due to unstable pressure. Combined with wireless or wired communication technology, it can realize remote monitoring and operation, improve management efficiency and system dynamic management, carry out system sewage discharge, reduce system failures, and prevent water from flowing back from the system side to the water supply side to pollute equipment and water system, thereby ensuring the normal operation of the system pipeline network.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
