Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a multifunctional water pump control valve. Background Art

[0002] A control valve, also known as a regulating valve, has a main structure similar to that of an ordinary valve. The valve body is opened and closed by an opening and closing piece. Some control valves are also equipped with electronic sensing components, which can automatically control the opening and closing of the valve body and control the flow rate of the fluid flowing through it. It is widely used in various industrial fields and is often used in fire protection facilities. The control valve can receive external fire signals and is in a closed state at ordinary times. It will automatically open when a fire occurs, thereby quickly outputting the fire extinguishing fluid to the high-pressure fine water mist nozzle, thereby achieving a rapid response to the fire and effectively reducing the loss of life and property caused by the fire.

[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the existing control valve is used in cold areas, if it is not opened and closed frequently, it is easy to cause condensation of ice between the valve disc and the valve body. Then, when the valve disc is raised to open the valve, the condensation of ice will freeze the valve disc and the valve body, making it difficult to open. Therefore, it is not suitable for use in cold areas and has poor applicability. Utility Model Content

[0004] The purpose of the utility model is to address the defects and shortcomings of the existing technology and provide a multifunctional water pump control valve that is convenient for clearing condensed ice and has strong applicability.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multifunctional water pump control valve, including a valve body and a lifting screw meshingly connected to the inner wall of the valve body, the bottom of the lifting screw is provided with a valve disc that can close the valve body, and the bottom surface of the valve body is provided with an impact frame penetrating at the corresponding position of the valve disc, the impact frame includes a plurality of impact tubes penetrating the bottom surface of the valve body, the impact tube includes a tube body and an upper punch column that slides and fits on the top of the inner wall of the tube body, the side wall of the upper punch column is provided with a lower pressure block that fits and slides with the inner wall of the tube body, the inner wall of the tube body is provided with a positioning piece, and an impact spring is provided between the positioning piece and the lower pressure block. When ice condenses on the valve disc and the valve body, the upper punch column is pulled down to cause the impact spring to generate elastic force, and then it is released to cause the upper punch column to move upward under the action of the elastic force to hit the condensed ice layer.

[0006] A further improvement is that the top end of the lifting screw is also provided with a control motor which is detachably connected to the top end of the valve body.

[0007] A further improvement is that a connecting flange is provided at the end of the valve body.

[0008] A further improvement is that the impact frame further includes a synchronization plate arranged at the lower end of the impact tube for connecting a plurality of impact tubes.

[0009] A further improvement is that a pull ring is provided on the bottom surface of the synchronization plate.

[0010] A further improvement is that an elastic frame is provided between the synchronization plate and the bottom end of the impact tube.

[0011] A further improvement is that a hemispherical impact head is provided on the top of the upper punch.

[0012] A further improvement is that a plurality of rollers are movably engaged on a surface of the pressing block close to the inner wall of the tube body.

[0013] After adopting the above technical solution, the beneficial effect of the utility model is as follows: when condensation ice is generated between the valve disc and the valve body, the utility model can pull down the upper punch, thereby synchronously driving the lower pressure block to squeeze the impact spring, thereby making the impact spring generate elastic force, and then release it to allow the upper punch to move upward quickly, thereby hitting the valve disc, repeatedly causing the condensation ice generated between the valve disc and the valve body to be broken, and the valve disc can be opened conveniently at this time, without disassembling the valve for de-icing, and it is easy to use, so that the control valve can be used smoothly in cold areas, and has strong applicability.

[0018] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0019] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a multifunctional water pump control valve, comprising a valve body 1 and a lifting screw 3 meshed with the inner wall of the valve body 1, the bottom of the lifting screw 3 is provided with a valve disc 2 that can close the valve body 1, the bottom surface of the valve body 1 is located at a corresponding position of the valve disc 2 and is penetrated by an impact frame 6, the impact frame 6 includes a plurality of impact tubes 61 penetrated and arranged on the bottom surface of the valve body 1, the impact tube 61 includes a tube body 21 and an upper punch 22 whose side wall slides and fits the top of the inner wall of the tube body 21, the side wall of the upper punch 22 is provided with a lower pressure block 23 that fits and slides with the inner wall of the tube body 21, the inner wall of the tube body 21 is provided with a positioning piece 24, and an impact spring 25 is provided between the positioning piece 24 and the lower pressure block 23. When ice condenses on the valve disc 2 and the valve body 1, the upper punch 22 is pulled down to cause the impact spring 25 to generate elastic force, and then released to cause the upper punch 22 to move upward under the action of the elastic force to hit the condensed ice layer. When in use, the end of the valve body 1 is When the valve body 1 is opened and closed, the valve disc 2 is lifted and lowered by rotating the lifting screw 3. When ice is generated between the valve disc 2 and the valve body 1, the upper punch 22 of the impact tube 61 of the impact frame 6 can be pulled down, thereby causing it to move downward along the tube 21, and at the same time, the lower pressure block 23 is driven downward to move downward, thereby squeezing the impact spring 25 arranged between the lower pressure block 23 and the positioning piece 24, thereby causing the impact spring 25 to generate elastic force. Then, the upper punch 22 can be quickly moved upward under the elastic force of the impact spring 25, so that the top of the upper punch 22 hits the valve disc 2, and the ice generated between the valve disc 2 and the valve body 1 is broken by the collision. At this time, the valve disc 2 can be opened conveniently without disassembling the valve for de-icing. It is easy to use and the control valve can be used smoothly in cold areas. It has strong applicability.

[0020] The top of the lifting screw 3 is also provided with a control motor 4 detachably connected to the top of the valve body 1, which is conducive to fully automatically controlling the rotation of the lifting screw 3 through signals, and the degree of automation is higher;

[0021] The end of the valve body 1 is provided with a connecting flange 5, which is conducive to making the connection between the valve body 1 and the pipeline more convenient and quick;

[0022] The impact rack 6 further includes a synchronization plate 62 disposed at the lower end of the impact tube 61 for connecting a plurality of impact tubes 61 , which facilitates pulling down a plurality of impact tubes 61 at once by pulling down the synchronization plate 62 , making it more convenient and quick to use, and a high-intensity upward impact effect can be generated by pulling down once;

[0023] The bottom surface of the synchronization plate 62 is provided with a pull ring 64, which is conducive to pulling down the synchronization plate 62 more quickly and conveniently;

[0024] An elastic frame 63 is provided between the synchronization plate 62 and the bottom end of the impact tube 61. When the synchronization plate 62 is pulled down, the elastic frame 63 generates elastic force. After the impact tube 61 has finished its upward impact, the elastic force of the elastic frame 63 can also cause the impact tube 61 to perform a second upward impact, thereby achieving a better effect of breaking the condensed ice.

[0025] The top of the upper punch 22 is provided with a hemispherical impact head 27, which is conducive to concentrating the impact force, thereby making the unit impact force greater and making it easier to destroy the condensed ice layer;

[0026] The lower pressing block 23 has a plurality of rollers 26 movably engaged on one side close to the inner wall of the tube body 21 . In this embodiment, there are five rollers 26 , which is beneficial to reducing the friction between the lower pressing block 23 and the tube body 21 , thereby making the resistance of pulling down the upper punch 22 smaller and easier to pull.

[0027] Working principle of the present invention: When the present invention is used, the end of the valve body 1 is installed in the water pump pipe to be controlled, and water can enter the valve body 1 and flow out from the other end of the valve body 1. The valve disc 2 is lifted and lowered by rotating the lifting screw 3 to control the opening and closing of the valve body 1. When ice condenses between the valve disc 2 and the valve body 1, the upper punch 22 of the impact tube 61 of the impact frame 6 can be pulled down, thereby causing it to move downward along the tube 21, and at the same time, the lower pressure block 23 is simultaneously driven to move downward, thereby squeezing the impact spring 25 arranged between the lower pressure block 23 and the positioning piece 24, thereby causing the impact spring 25 to generate elastic force. Then, the hand is released, and the upper punch 22 can be quickly moved upward under the elastic force of the impact spring 25, so that the top of the upper punch 22 hits the valve disc 2. This is repeated many times, so that the condensation generated between the valve disc 2 and the valve body 1 is broken. At this time, the valve disc 2 can be opened conveniently without disassembling the valve for de-icing. It is easy to use, so that the control valve can be used smoothly in cold areas and has strong applicability.
