Embodiment Construction

[0012] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Depend on Figure 1 to Figure 2 Given, an intelligent reversing valve includes a valve body 1 with a cylindrical cavity and a valve stem 2. The valve stem 2 runs through the valve body 1 up and down and is connected with the valve body 1 to seal and slide up and down. The left side of the valve body 1 is provided with There is an inlet 3 in the middle, and the right side of the valve body 1 is provided with a first outlet 4 and a second outlet 5 at intervals, and the inlet 3 is located between the first outlet 4 and the second outlet 5. It is characterized in that the valve stem 2 A first spool 6 and a second spool 7 are fixed on the top, the first spool 6 is set at one end close to the first outlet 4, the second spool 7 is set at one end close to the second outlet 5, and the valve stem 2 is set at the end close t...

Abstract

The invention discloses an intelligent reversing valve. A first valve core is arranged at the end close to a first outlet, a second valve core is arranged at the end close to a second outlet, and theupper end of a valve rod extends into a control shell; a threaded section is arranged at the end, extending into the shell, of the valve rod, and is spirally connected with a screw sleeve, the screw sleeve is connected with a driven gear in an up-down sliding mode, and a driving gear meshing with the driven gear is mounted on an output shaft of a stepping motor; the driven gear is rotationally fixed to the shell, a mounting rod is arranged at the lower part of the shell and provided with a rotating pin, and the length from the rotating pin to a valve body is adjustable; and the rotating pin isrotationally connected with a detachable control rod, the middle of the control rod is rotationally connected with the rotating pin, a driving pin is arranged at the end, extending out of the valve body downwards, of the valve rod, a driving groove is formed in the end, facing the valve cores, of the control rod, and the driving pin extends into the driving groove to be slidably connected with the driving groove. Operation is simple, stability is high, a manual mode is mainly operated under emergencies or accidents such as power outage, and the reliability of the reversing valve is improved.

Description

technical field [0001] The invention relates to the technical field of valve equipment, in particular to an intelligent reversing valve. Background technique [0002] The valve is a control component in the fluid delivery system, which has the functions of cut-off, adjustment, flow diversion to prevent reverse flow, pressure stabilization or overflow and pressure relief. There are many control methods for valves, such as manual, electric, hydraulic, pneumatic, electromagnetic, etc., which can act according to predetermined requirements under the action of pressure, temperature or other forms of sensing signals, or do not rely on sensing The valve is simply opened or closed by the signal, and the valve relies on the driving or automatic mechanism to make the opening and closing parts lift, slide, swing or rotate, thereby changing the size of its flow channel to realize its control function. In the treatment of sewage sludge, or in the production and transmission of granular ...
