Detailed Description of the Invention

[0023] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The control system of a quick-release and quick-replacement rubber hose valve of the present invention is as Figure 1 shown, and includes a programmable controller 01, a rubber hose valve 02, a motor driver 03 and a servo motor 04. The programmable controller 01 sends a pulse signal to the motor driver 03, so that the servo motor 04 rotates. The servo motor 04 is the power source of the rubber hose valve 02, and its rotation drives the double-headed screw 2 to rotate. Through the threaded structure of the front pull plate 3 and the rear pull plate 4 with the double-headed screw 2, the rotational motion is converted into a linear motion, so as to drive the front clip 5 and the rear clip 6 to clamp or loosen towards each other, thereby realizing the opening, closing or opening degree adjustment of the rubber hose 2.

[0025] A quick-release and quick-replacement rubber hose valve of the present invention is as Figure 2 , Figure 3As shown in the figure, it is composed of a rubber hose 1, a fixed valve seat 10, a movable valve seat 11, a ring buckle screw 13, a perforated nut 14, a quick-release lever 9, a bearing seat 12, a double-headed screw 2, a front pull plate 3, a rear pull plate 4, a front clip 5, a rear clip 6, a connecting screw 7 and a handwheel 15. Among them, the rubber hose 1 is composed of a straight rubber hose section and circular fixing plates perpendicular to the rubber hose section at both ends. On both sides of the rubber hose section of the rubber hose 1, there is an ear 17 symmetrically, both of which are U-shaped, forming a closed through hole. The bearing seat 12, the double-headed screw 2, the front pull plate 3, the rear pull plate 4, the front clip 5, the rear clip 6, the connecting screw 7 and the quick-release lever 9 form a rubber hose clamping and opening / closing mechanism. The bearing seat 12 is fixedly connected to the fixed valve seat 10 and is movably connected to the double-headed screw 2. The front pull plate 3, the rear pull plate 4, the front clip 5 and the rear clip 6 are arranged in sequence. The front clip 5 and the rear clip 6 are respectively located on the opposite sides of the rubber hose 1. The two ears of the rubber hose 1 are respectively nested on the front clip 5 and the rear clip 6. The rear pull plate 4 and the front clip 5 are fixedly connected. One end of the front pull plate 3 and the rear clip 6 corresponding to each other is fixedly connected by the connecting screw 7 and the nut 8, and the other end corresponding to each other is provided with an opening groove and is connected by the quick-release lever 9. The front pull plate 3 and the rear pull plate 4 are provided with internal threads with opposite helix directions, which are matched with the external threads with opposite helix directions of the double-headed screw rod (2). At the same time, the quick-release lever 9 and the opening grooves at the other ends of the front pull plate 3 and the rear clip 6 corresponding to each other form a movable connection mechanism of the opening / closing mechanism. The rear side end of the fixed valve seat 10 is provided with a first screw mounting seat, which is a double-ear mounting seat with a fixed shaft and a mounting groove. The corresponding end of the ring buckle screw 13 is provided with a shaft hole for cooperating with the fixed shaft. The rear side end of the movable valve seat 11 is provided with a second screw mounting seat, which is a rectangular body mounting seat with a shaft hole or an opening groove. The corresponding end of the ring buckle screw 13 is matched with the shaft hole or the opening groove. The ring buckle screw 13, the perforated nut 14, the first screw mounting seat and the second screw mounting seat form a valve seat movable connection mechanism. The inner sides of the fixed valve seat 10 and the movable valve seat 11 adjacent to each other are both provided with grooves for cooperating with the rubber hose 1 and the rubber hose clamping and opening / closing mechanism, and semi-circular mounting blocks for cooperating with the fixing plates at both ends of the rubber hose 1. The fixed valve seat 10 is buckled and fixedly connected to the movable valve seat 11 through the ring buckle screw 13 and the perforated nut 14. The handwheel 15 and the coupling 16 are a driving connection mechanism, which is installed and fixed on the screw end of the double-headed screw 2 extending out of the outer end of the bearing seat 12 and can be drivingly connected to the servo motor 04, and is a cross-slider structure. The handwheel 15 is an emergency manual rotation wheel.

[0026] The fixed valve seat 10 is movably connected to the ring buckle nut 13 and is buckled and connected to the movable valve seat 11 through the perforated nut 14. When disassembly is required, only the perforated nut 14 needs to be loosened, and the movable valve seat 11 and the fixed valve seat 10 can be separated. The quick-release lever 9 is movably connected to the open slot of the front pull plate 3 and is movably connected to the open slot of the rear clip 6. When the quick-release lever is located in the open slot, the front pull plate 3 and the rear clip 6 can be connected together for opening and closing movements; when it is necessary to take out the rubber hose 1, only the quick-release lever 9 needs to be taken out from the open slots of the front pull plate 3 and the rear clip 6, and the rubber hose 1 can be taken out for replacement.

[0027] After replacing the rubber hose, place the quick-release lever 9 in the open slots of the front pull plate 3 and the rear clip 6. The movable valve seat 11 is buckled to the fixed valve seat 10 through the ring buckle screw 13, and tightening the perforated nut 14 completes the maintenance of the quick-release and quick-replacement rubber hose valve and restores its use.

[0028] The device of the present invention is driven by the double-headed screw 2 to convert the rotational motion of the motor into the linear motion of the front clip 5 and the rear clip 6, realizing the opening, closing or opening degree adjustment of the rubber hose valve. The quick disassembly of the movable valve seat 11 and the quick-release lever 9 enables the rubber hose 1 to be taken out of the valve body very quickly for replacement.

[0029] The drive motor 04 of the device of the present invention is connected to the rubber hose valve through the coupling 16. The coupling 16 is of a cross-slider structure, enabling quick disassembly and assembly of the rubber hose valve without using other tools to disassemble and assemble screws.

[0030] The above embodiments are only exemplary descriptions of this patent and do not limit its protection scope. Those skilled in the art can also make partial changes to it. As long as they do not exceed the spiritual essence of this patent, they are within the protection scope of this patent.
