Description

Technical Field

[0001] The invention relates to a slurry valve, in particular to a ceramic throttling Y-type slurry valve. Background Art

[0002] In modern industrial production, the fields involving slurry transportation and control are extensive, such as chemical, mining, environmental protection, food processing and other industries. With the continuous development of these industries, the requirements for precise control and efficient operation in the slurry treatment process are increasing. Slurry is usually corrosive, abrasive and sticky. Its special physical and chemical properties make traditional valves face many challenges when applied to slurry transportation systems. This has prompted valves designed specifically for slurry conditions. The sealing structure of ordinary valves is mostly plane or conical seals. Under slurry conditions, solid particles are easily embedded in the sealing surface, resulting in poor sealing. Sealing materials commonly used in traditional valves, such as rubber and polytetrafluoroethylene, are prone to aging, deformation, and loss of sealing when facing highly corrosive substances in slurry (such as acid and alkali solutions in the chemical industry) or high temperature environments (such as hot slurry transportation in the mining industry). For example, rubber seals will undergo chemical corrosion after long-term contact with acidic slurry, resulting in seal failure, increasing maintenance costs and safety risks. The Y-shaped design makes the flow path of the valve smoother, reduces the resistance and turbulence of the slurry flow, and reduces the scouring and wear of the internal parts of the valve. However, the materials used in the Y-shaped slurry valve in the prior art have poor corrosion resistance, and the friction between the valve core and the valve body when the valve core moves in the valve body cannot be avoided, causing wear. When adjusting the flow rate, it is necessary to manually adjust the flow rate, and the error in determining the flow rate leads to inaccurate adjustment. The existing control device structure is too complicated, which often makes the actual operation unstable when used. Summary of the invention

[0031] The present invention provides a new technical solution: a ceramic throttling Y-type slurry valve, comprising a support frame 1, a limit rod 2, a valve stem 3, a valve core 4, a connecting piece 5, a driving device, a flow sensor 6, and a controller 7. A valve body is fixedly installed below the support frame 1, and the driving device is fixedly installed above the support frame 1. One end of the limit rod 2 is movably connected to the support frame 1, and the other end of the limit rod 2 is movably connected to the valve stem 3. One end of the valve stem 3 is connected to the output end of the driving device, and the other end of the valve stem 3 is provided with a valve core 4, which is arranged in the valve body. The flow sensor 6 is fixedly installed on the liquid inlet of the valve body through the connecting piece 5, and the controller 7 is connected to the driving device.

[0032] The flow sensor 6 is used to monitor the flow rate of liquid when it enters the valve body, and the controller 7 is used to control the driving device, and the driving device is used to control the movement of the valve stem 3 in the valve body.

[0033] In this embodiment, the valve body includes a left valve body 8, a right valve body 9, a sealing cover 10, a packing 11, a sealing ring 12, and a sealing gasket 16. The left valve body 8 is flange-connected to the right valve body 9. The sealing cover 10 is fixedly connected to the top of the right valve body 9. The sealing gasket 16 is arranged at the connection between the left valve body 8 and the right valve body 9. The packing 11 is arranged between the sealing cover 10 and the valve stem 3. The sealing ring 12 is arranged on the valve stem 3 and is fixed by the packing 11. The support frame 1 is arranged above the sealing cover 10.

[0034] In this embodiment, the driving device includes an electric actuator 13, a transmission screw 14, and a driving handle 15. The driving handle 15 is installed at the upper end of the electric actuator 13 and connected to the transmission screw 14. The lower end of the transmission screw 14 is threadedly connected to the valve stem 3. The electric actuator 13 is used to control the rotation of the transmission screw 14.

[0035] In this embodiment, the sealing gasket 16 is made of rubber, and the opening in the middle can fit with the valve core 4 .

[0036] In this embodiment, the limiting rod 2 is a telescopic T-shaped connecting rod.

[0037] In this embodiment, the controller 7 is configured as a PLC controller, using Mitsubishi FX3U, and the output end of the controller is connected to the input end of the electric actuator 13 .

[0038] In this embodiment, the flow sensor 6 is an Ausun AFD4 liquid flow meter.

[0039] In this embodiment, the cross section of the valve core 4 is trapezoidal.

[0040] In this embodiment, the inner walls of the left valve body 8 and the right valve body 9 are both made of ceramic.

[0041] In this embodiment, the ceramic throttling Y-type slurry valve is used as follows:

[0042] The flow sensor 6 collects liquid flow information and sends the collected information to the controller 7;

[0043] If the liquid flow rate exceeds or falls below a set value, the controller 7 will control the driving device to adjust the opening of the valve core 4 .

[0044] Working principle: When the present invention is in use, the flow sensor 6 is connected to the liquid inlet of the left valve body 8 through the connecting piece 5, the left valve body 8 is flange-connected to the right valve body 9, and the liquid outlet is set at the right valve body 9. When the liquid enters the valve body, the flow sensor 6 will monitor the flow in the valve body in real time and transmit it to the controller 7. The controller 7 controls the driving device according to the set value. The controller 7 drives the electric actuator 13 to control the driving handle 15 to drive the transmission screw 14 to rotate. The valve stem 3 will move up and down as the transmission screw 14 rotates. This is because the connection relationship between the valve stem 3 and the transmission screw 14 is a threaded connection and is limited by the limit rod 2, so there will be no rotation. The limit rod 2 will expand and contract as the valve stem 3 moves up and down. A valve core 4 is set at one end of the valve stem 3. The position of the valve core 4 in the valve body is controlled to achieve the effect of controlling the flow. The output port of the controller 7 is directly connected to the control input end of the electric actuator 13 through a wire. If it is digital signal control, generally only three pins, namely, forward, reverse and common end, need to be connected; if it is analog signal control, the analog signal input pin also needs to be connected.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
