Description

Technical Field

[0001] This utility model relates to the field of fire valve technology, specifically to a fire valve with flow regulation function. Background Technology

[0002] Fire valves are an important control accessory in industrial and building pipelines. Their main structure includes a valve body, an opening and closing mechanism, a valve cover, and sealing elements. Fire valves have many advantages, such as low fluid resistance, strong corrosion resistance, strong sealing performance, and easy opening and closing, and play a crucial role in fire prevention and control.

[0003] However, most existing valves cannot regulate the flow rate of the water, which means that the water output is limited by the height of the valve plate itself and the height it can be moved upward, making it impossible to control and regulate the flow rate to improve water utilization. Utility Model Content

[0004] The purpose of this invention is to provide a fire valve with flow regulation function to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A fire valve with flow regulation function includes a fire valve, wherein an adjustment component is provided on the top of the fire valve, a telescopic valve is provided on the surface of the adjustment component, and a support component is provided on the surface of the telescopic valve.

[0007] The telescopic valve includes a gate body unit and a lifting unit. The lifting unit is disposed on the surface of the gate body unit. The gate body unit includes a valve main plate and a valve sub plate. The lifting unit includes a limit rod and a second screw handle.

[0008] A further improvement of the present invention is that the fire valve includes a fire valve body, an inner circular groove plate is fixedly installed on the bottom surface of the inner cavity of the fire valve body, and a top partition plate is fixedly installed on the inner wall of the fire valve body. The inner circular groove plate can be used in conjunction with a telescopic valve to seal the interior of the fire valve body.

[0009] A further improvement of the present invention is that the adjusting component includes a sealing disc bolted to the top of the fire valve body, a first screw handle threaded through the surface of the sealing disc, and a fixing block slidably mounted at the bottom end of the first screw handle.

[0010] A further improvement of this utility model is that: the top end of the main valve plate and the bottom end of the fixing block are fixedly connected, the auxiliary valve plate is slidably installed at the bottom of the main valve plate, and the surface of the auxiliary valve plate and the inner wall of the main valve plate are sealed and slidably connected. By setting a telescopic valve, the fire valve can be opened and closed in conjunction with the adjustment component. Because the main and auxiliary plates are set, secondary adjustment can be achieved after the valve body is opened for the first time. Thus, the auxiliary valve plate can be moved up to effectively expand the valve body opening and increase the flow rate of the water outlet.

[0011] A further improvement of this utility model is that: one end of the limiting rod is slidably connected to the top of the valve sub-plate, and one end of the second screw handle is slidably connected to the top of the valve sub-plate and is away from the limiting rod. By setting a lifting unit, after the valve body is opened by using the adjusting component to drive the telescopic valve as a whole to move upward, the second screw handle can be rotated to cooperate with the limiting rod to drive the valve sub-plate to move upward to achieve secondary adjustment, thereby expanding its flow regulation function.

[0012] A further improvement of this utility model is that the support assembly includes a plug rod that is inserted and installed on the top of the valve sub-plate. A fixed support rod is fixedly installed on the top surface of the plug rod, and a movable support rod is slidably installed on the surface of the plug rod. A spring is fixedly installed between the fixed support rod and the movable support rod. By setting the support assembly, the valve body can be supported by the support rod when the valve body is opened to release water, thereby preventing the valve main plate from deforming easily due to the reduced thickness after slotting caused by the pressure of the water flow, which would affect the vertical adjustment of the valve sub-plate.

[0013] A further improvement of this utility model is that: the surface of the limiting rod is slidably connected to the inner wall of the valve main board, the second screw handle is threadedly connected to the valve main board, the surfaces of both the limiting rod and the second screw handle are slidably and sealingly connected to the inner wall of the sealing disc, and both the limiting rod and the second screw handle pass through the fixed support rod and the movable support rod without being connected. The slidable and sealing connection can prevent water leakage and does not affect the adjustment.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a fire valve with flow regulation function. By setting a telescopic valve, it is possible to open and close the fire valve in conjunction with the regulating component. Because of the setting of main and auxiliary plates, secondary adjustment can be achieved after the valve body is opened for the first time. Thus, the valve auxiliary plate can be moved up to effectively expand the valve body opening and increase the water flow.

[0016] 2. This utility model provides a fire valve with flow regulation function. By setting up a lifting unit, after the valve body is opened by using the adjustment component to drive the telescopic valve to move upward, the second screw handle can be rotated in conjunction with the limit rod to drive the valve sub-plate to move upward to achieve secondary adjustment, thereby expanding its flow regulation function.

[0017] 3. This utility model provides a fire valve with flow regulation function. By setting a support component, the valve body can be supported by the support rod when the valve body is opened to discharge water, thereby preventing the main valve plate from deforming due to the reduced thickness after the groove is cut by the water flow, which would affect the vertical adjustment of the valve sub-plate.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides a fire valve with flow regulation function, including a fire valve 1. The fire valve 1 includes a fire valve body 11. An inner circular groove plate 12 is fixedly installed on the bottom surface of the inner cavity of the fire valve body 11. A top partition plate 13 is fixedly installed on the inner wall of the fire valve body 11. An adjustment component 2 is provided on the top of the fire valve 1. A telescopic valve 3 is provided on the surface of the adjustment component 2. A support component 4 is provided on the surface of the telescopic valve 3. The telescopic valve 3 includes a gate unit and a lifting unit. The lifting unit is provided on the surface of the gate unit. The gate unit includes a valve main plate 31 and a valve sub plate 32. The lifting unit includes a limit rod 33 and a second screw handle 34. By setting the telescopic valve 3, the fire valve 1 can be opened and closed in conjunction with the adjustment component 2. Because of the main and sub plates, a secondary adjustment can be achieved after the valve body is opened for the first time. Thus, the valve sub plate 32 can be moved upward to effectively expand the valve body opening and increase the water flow.

[0027] Example 2

[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the adjusting component 2 includes a sealing disc 21 bolted to the top of the fire valve body 11. A first screw handle 22 is threaded through the surface of the sealing disc 21. A fixing block 23 is slidably installed at the bottom end of the first screw handle 22. The top end of the valve main plate 31 is fixedly connected to the bottom end of the fixing block 23. The valve sub-plate 32 is slidably installed at the bottom of the valve main plate 31, and the surface of the valve sub-plate 32 is slidably connected to the inner wall of the valve main plate 31. One end of the limiting rod 33 is slidably connected to the top of the valve sub-plate 32. One end of the second screw handle 34 is slidably connected to the top of the valve sub-plate 32 and is away from the limiting rod 33. By setting a lifting unit, after the adjusting component 2 drives the telescopic valve 3 to move upward to open the valve body, the second screw handle 34 can be rotated to cooperate with the limiting rod 33 to drive the valve sub-plate 32 to move upward to achieve secondary adjustment, thereby expanding its flow regulation function.

[0029] Example 3

[0030] like Figure 1-5As shown, based on embodiments 1-2, this utility model provides a technical solution: Preferably, the support component 4 includes a plug rod 41 inserted and installed on the top of the valve sub-plate 32. A fixed support rod 42 is fixedly installed on the top surface of the plug rod 41, and a movable support rod 44 is slidably installed on the surface of the plug rod 41. A spring 43 is fixedly installed between the fixed support rod 42 and the movable support rod 44. The surface of the limiting rod 33 is slidably connected to the inner wall of the valve main plate 31. The second screw handle 34 is threadedly connected to the valve main plate 31. The surfaces of the limiting rod 33 and the second screw handle 34 are both slidably connected to the inner wall of the sealing disc 21. The limiting rod 33 and the second screw handle 34 both pass through the fixed support rod 42 and the movable support rod 44 but are not connected. By setting the support component 4, the valve body 31 can be supported by the support rod when the valve body is opened to release water, thereby preventing the valve main plate 31 from deforming easily due to the reduced thickness after slotting caused by the pressure of the water flow, which would affect the vertical adjustment of the valve sub-plate 32.

[0031] The working principle of fire valves with flow regulation function will be explained in detail below.

[0032] like Figure 1-5 As shown, when the fire valve is in use, the entire fire valve is sealed and installed on the water supply pipe by bolts. When it is needed, the first screw handle 22 is rotated so that the fixing block 23 moves the telescopic valve 3 upward inside the fire valve 1, thereby creating a groove between the inner circular groove plate 12 and the telescopic valve 3 to facilitate water discharge.

[0033] When a larger water output is required, the second screw handle 34 can be rotated in conjunction with the limit rod 33 to allow the valve sub-plate 32 to continue to move upward within the valve main plate 31, thereby increasing the size of the slot and the water output. Furthermore, the support rod, being connected to the inner wall of the valve main plate 31, can withstand a certain amount of impact force to prevent it from deforming due to high-pressure impact.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
