Description

Technical Field

[0001] The utility model relates to the field of fluid cleaning equipment, in particular to a polytetrafluoroethylene valve body water gun cleaning system. Background Art

[0002] Polytetrafluoroethylene (PTFE) valve bodies are widely used in chemical, pharmaceutical, food and other places with high requirements for valve cleanliness due to their excellent corrosion resistance, high temperature resistance and lubrication performance. However, during the production and subsequent processing of the valve body, various dust, processing debris and oil stains are easily attached, and high-pressure water or other media flushing is required to obtain a clean surface. The traditional manual water gun flushing method is inefficient and uncertain, and it is difficult to meet the needs of large-scale production and high cleanliness.

[0003] Therefore, a system is needed that can automatically and efficiently perform high-pressure water flushing on the PTFE valve body and cooperate with the necessary valve body rotation or lifting action to ensure that all surfaces of the valve body can be thoroughly cleaned. Utility Model Content

[0004] The utility model aims to provide a polytetrafluoroethylene valve body water gun cleaning system. The polytetrafluoroethylene valve body water gun cleaning system realizes multi-angle high-pressure water washing of the valve body through the coordinated work of a high-pressure water pump, a rotating mechanism and a lifting mechanism.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A polytetrafluoroethylene valve body water gun cleaning system includes: three-phase AC power supplies L1, L2, L3 and a main switch QF; the main switch QF is connected to a power circuit and a control circuit; wherein the power circuit includes contactors KM1 and KM2 arranged in parallel, which are respectively connected to motors M1 and M2; the control circuit includes a switch SB1, and the switch SB1 is connected to a high-pressure water gun circuit, a turntable circuit, a lifting circuit and a total timing circuit.

The coordination of four functional circuits (high-pressure water gun, turntable, lifting and total timing circuit) realizes three-dimensional cleaning. The control circuit ensures the precise connection of the cleaning process through the cascade control of multiple groups of time relays: first, the high-pressure water gun is started to rinse the bottom, and at the same time, the turntable rotates slowly to ensure uniform circumferential cleaning. After completing the cleaning of a height position, the lifting device lifts the turntable to a new height to continue cleaning. The system controls the overall operation time through the total timing circuit. Through the progressive control of three time relays, the automatic coordination of water gun spraying, turntable rotation and height lifting is realized. This design improves cleaning efficiency and quality. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0018] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, a polytetrafluoroethylene valve body water gun cleaning system includes three-phase AC power supplies L1, L2, L3 and a main switch QF. The main switch QF is connected to a power circuit and a control circuit.

[0021] The power circuit includes a motor M1 and a motor M2. The motor M1 and the motor M2 are connected to contactors KM1 and KM2 respectively. The contactors KM1 and KM2 are arranged in parallel. The operation of the motors M1 and M2 is controlled by opening and closing the contactors KM1 and KM2.

[0022] Among them, the motor M1 is a motor for driving the turntable to rotate. The corresponding polytetrafluoroethylene valve body is installed on the turntable, and the turntable can be driven to rotate slowly by the motor M1.

[0023] The motor M2 is the power source of the lifting device in the vertical direction, and the lifting device can be chain-driven, belt-driven, etc. The motor M2 is used to move the turntable as a whole in the longitudinal direction, and the position of the valve body in the longitudinal direction can be adjusted by the motor M2, so as to flush the valve body at different height positions.

[0024] The control circuit includes a switch SB1. The switch SB1 is connected to a high-pressure water gun circuit 1, a turntable circuit 2, a lifting circuit 3, and a total time circuit 4. The operator closes and opens the control circuit by operating the sliding switch SB1.

[0025] The high-pressure water gun circuit 1 includes a normally closed switch KT2, which is connected to a normally closed switch KT3. The normally closed switch KT3 is connected to a normally closed switch KT1. The normally closed switch KT1 is connected to a solenoid valve EV. At the same time, the normally closed switch KT1 is connected to a power-on delay time relay KT1.

[0026] As mentioned above, when the switch SB1 is closed, the current flows through the normally closed switch KT2, the normally closed switch KT3 and the normally closed switch KT1, so that the solenoid valve EV is energized. When the solenoid valve is energized, the water gun is opened, and the water flushes the bottom of the valve body fixed on the turntable. At the same time, the time relay KT1 is energized, thereby starting the timing. At the end of the timing, the normally closed switch KT1 is disconnected, so that the solenoid valve EV loses power and the solenoid valve is closed.

[0027] The turntable circuit 2 includes a normally closed switch KT2. The normally closed switch KT2 is connected to a normally closed switch KT3. The normally closed switch KT3 is connected to a normally closed switch KT1. The normally closed switch KT1 is connected to a relay KM1.

[0028] When the control circuit is powered on, current flows through the normally closed switch KT2, the normally closed switch KT3, and the normally closed switch KT1, so that the relay KM1 is powered on. The relay KM1 is powered on, so that the contactor KM1 is closed, thereby making the motor M1 work, driving the turntable to rotate slowly, and the high-pressure water gun fully cleans the outer shell of each position of the valve body that rotates on the turntable.

[0029] When the timing of the time relay KT1 ends, the normally closed switch KT1 in the turntable circuit is disconnected, so that when the solenoid valve is closed and no water is discharged, the turntable stops rotating.

[0030] The lifting circuit 3 includes a normally open switch KT1. The normally open switch KT1 is connected to a normally closed switch KT3. The normally closed switch KT3 is connected to a normally closed switch KT2. The normally closed switch KT2 is connected to a relay KM2. At the same time, the normally closed switch KT2 is connected in parallel to a power-on delay time relay KT2.

[0031] When the timing of time relay KT1 ends, the normally open switch KT1 closes, so that relay KM2 is energized, contactor KM2 is closed, and motor M2 works, driving the turntable to lift a small position as a whole. At the same time, time relay KT2 starts timing to control the lifting amplitude. When the timing of time relay KT2 ends, the normally closed switch KT2 is disconnected, causing relay KM2 to lose power, motor M2 to stop, and the lifting process ends.

[0032] At the same time, the normally closed switch KT2 in the high-pressure water gun circuit and the turntable circuit is disconnected, causing the time relay KT1 to lose power, and then the normally open switch KT1 in the lifting circuit is disconnected. At this time, the entire circuit is reset, the turntable rotates, and the solenoid valve is re-energized to start flushing and lifting the valve body to a certain position. Repeat the above process so that each outer shell surface of the valve body is flushed by the water gun, achieving a better flushing effect.

[0033] The total timing circuit 4 includes a power-on delay time relay KT3. When the control circuit is powered on, the time relay KT3 always keeps the timing state. After the outer surface of the valve body is flushed, the time relay KT3 ends the timing, so that the normally closed switches KT3 in each circuit are disconnected and the whole system is shut down.

[0034] In order to further improve the cleanliness of flushing, the valve body can be turned upside down and the water gun can be set at an angle for the next round of cleaning.

[0035] Optimally, the timing time of the time relay KT3 is greater than the timing time of the time relay KT1, and the timing time of the time relay KT1 is greater than the timing time of the time relay KT2.

[0036] The present invention drives the valve body to rotate through a turntable, and uses a solenoid valve to flexibly control the spraying time of a high-pressure water gun, and drives the valve body to change its height position through a lifting circuit, thereby performing multi-angle and sufficient high-pressure cleaning on the surface of the valve body, thereby improving the cleaning efficiency and quality.

[0037] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
