[0023] 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.

[0024] like Figure 1-4 As shown, a mechanical water flow linkage valve for a kitchen fire extinguishing device includes a valve body 1, a valve cover 2 is detachably connected to the top of the valve body 1, and a fixed pipe 3 is fixedly connected to one side of the valve body 1, and one end of the fixed pipe 3 is fixedly connected to a flange 4, a valve plate assembly 5 is provided inside the valve body 1, and a fixing assembly 6 is provided on the top of the valve cover 2; the valve plate assembly 5 includes a slot 501, a sealing valve seat 502 is provided on the inner wall of the valve body 1, and the inner wall of the sealing valve seat 502 is fixedly connected to a fixing seat 503, and the inner wall of the fixing seat 503 is fixedly connected to a spring 504, and one end of the spring 504 is fixedly connected to the inner wall of the fixing seat 503. A fixed block 505 is fixedly connected, a fixed valve plate 506 is slidably connected to the inner wall of the slot 501, and a mounting groove 507 is provided on the inner wall of the fixed valve plate 506; the fixed assembly 6 includes a first fixed plate 601, a second fixed plate 602 is fixedly connected to the top of the valve cover 2, a sliding groove 603 is provided on the inner wall of the first fixed plate 601, and a clamping block 604 is slidably connected to the inner wall of the sliding groove 603, one end of the clamping block 604 is fixedly connected to a fixed handle 605, and the outer wall of the clamping block 604 is fixedly connected to a baffle 606, and a clamping groove 607 is provided on the inner wall of the fixed valve plate 506.

[0025] By means of the above technical solution, in an emergency, the block 604 can be pulled out of the card slot 607 of the fixed valve plate 506 by pulling the fixed handle 605. At this time, the fixed block 505 in the fixed seat 503 quickly pushes up the fixed valve plate 506 with the help of the elastic force of the spring 504, thereby exposing the opening and allowing the water to flow smoothly. The entire operation process is simple and the time required is short. The fire extinguishing water flow can be quickly started at a critical moment, meeting people's needs. By pulling the fixed handle 605, the block 604 can be well driven to move, and the block 604 moves more stably in the slide 603. With the support of the first fixed plate 601 and the second fixed plate 602, the block 604 can be stably placed or moved. The baffle 606 is provided to prevent the block 604 from falling off the slide 603. The operation is simple and easy to use.

[0026] Specifically, the valve cover 2 forms a sliding structure with the fixed valve plate 506 through the slot 501 , and one end of the fixed valve plate 506 extends into the slot 501 .

[0027] Through the above technical solution, a slot 501 is opened on the inner wall of the valve cover 2, and a first fixed plate 601 is fixedly connected to the top of the valve cover 2. A sealing ring is provided in the slot 501 to enhance the sealing performance; the connection effect between the valve cover 2 and the slot 501 and the fixed valve plate 506 is enhanced, which facilitates the movement of the fixed valve plate 506 in the slot 501.

[0028] Specifically, the shape and size of the inner wall of the sealing valve seat 502 match the shape and size of the outer wall of the fixed valve plate 506 , and the inner wall of the sealing valve seat 502 fits the outer wall of the fixed valve plate 506 .

[0029] Through the above technical solution, the connection effect between the sealing valve seat 502 and the fixed valve plate 506 is enhanced, and the sealing performance between the sealing valve seat 502 and the fixed valve plate 506 is enhanced by providing the sealing valve seat 502.

[0030] Specifically, the fixing seat 503 forms an elastic structure with the fixing block 505 through the spring 504 , and one end of the fixing block 505 extends into the fixing seat 503 to be connected with the spring 504 .

[0031] Through the above technical solution, the connection effect between the fixing seat 503, the spring 504 and the fixing block 505 is strengthened. When the fixing block 505 moves downward, the fixing block 505 moves downward to contract the spring 504, so that the spring 504 can better play its own effect.

[0032] Specifically, the shape and size of the inner wall of the installation groove 507 match the shape and size of the outer wall of the fixing seat 503 , and the inner wall of the installation groove 507 fits closely with the outer wall of the fixing seat 503 .

[0033] Through the above technical solution, the connection effect between the installation groove 507 and the fixed seat 503 is enhanced, which facilitates the fixed valve plate 506 to slide on the fixed seat 503 through the installation groove 507.

[0034] Specifically, the first fixing plate 601 forms a sliding structure with the clamping block 604 through the sliding groove 603 , and the outer wall of the clamping block 604 fits with the inner wall of the sliding groove 603 .

[0035] Through the above technical solution, the connection effect between the first fixing plate 601 and the sliding groove 603 and the clamping block 604 is strengthened, and when the clamping block 604 moves, it is convenient for the clamping block 604 to move in the sliding groove 603.

[0036] Specifically, the shape and size of the card block 604 match those of the card slot 607 , and one end of the card block 604 extends into the card slot 607 .

[0037] Through the above technical solution, the connection effect between the clamping block 604 and the clamping groove 607 is enhanced. When one end of the clamping block 604 extends into the clamping groove 607, the fixed valve plate 506 can be limited.

[0038] When in use, first, the valve body 1 can be connected to the pipeline through the flanges 4 at both ends. In an emergency, when a fire-fighting water flow is needed, the spring 504 is in a retracted state. The operator pulls the fixed handle 605, and the fixed handle 605 drives the block 604 to move more stably in the slide groove 603. The block 604 drives the baffle 606 to move, and one end of the block 604 moves out of the slot 607 of the fixed valve plate 506, releasing the limit of the fixed valve plate 506. The spring 504 rebounds from the retracted state, and the fixed block 505 in the fixed seat 503 quickly pushes the fixed valve plate 506 up with the elastic force of the spring 504, and the fixed valve plate 506 moves more stably in the slot 501. The fixed valve plate 506 moves up to expose the opening, allowing water to flow smoothly. The entire operation process is simple and the time required is short. The fire-fighting water flow can be quickly started at a critical moment, meeting people's needs. This completes all work. The content not described in detail in this specification belongs to the existing technology well known to professional and technical personnel in this field.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of this application is defined by the appended claims and their equivalents.
