[0002] A cock valve is a rotary valve with a closing member or a plunger shape. By rotating 90 degrees, the channel opening on the valve plug communicates or separates from the channel opening on the valve body to achieve opening or closing. It is a kind of valve. The shape of its valve plug can be cylindrical or conical. In a cylindrical valve plug, the channel is generally rectangular; while in a conical valve plug, the channel is trapezoidal. These shapes make the structure of the cock valve light. It is most suitable for cutting off and connecting media and for shunting applications. However, depending on the nature of the application and the erosion resistance of the sealing surface, it can sometimes also be used for throttling.

The cock axially extends to set a rotating shaft. The valve cover and the valve seat are connected by positioning screws and form a cock cavity for accommodating the cock. The cock is rotatably arranged in the cock cavity. The adjusting screw is arranged on the valve cover, and the cock can be slightly moved downward by pushing the adjusting screw. The handle is connected to the rotating shaft of the cock to drive the cock to rotate; the valve body includes: an installation cavity, which is formed by inward depression from the top of the valve body; the valve cover bolt fixes the valve body and the valve cover through a valve cover nut to realize the installation of the upper assembly and the valve body.

[0031] Example 1, please refer to Figures 1 - 4 , the present utility model provides a technical solution: a quick-opening valve with replaceable core and cock for heating ventilation, including a quick-opening valve body 1. A sealing cover 104 is movably connected to the top of the quick-opening valve body 1. A plurality of bolts 103 are threadedly connected inside the sealing cover 104, and the plurality of bolts 103 are threadedly connected to the top of the quick-opening valve body 1. A sealing bearing 108 is fixedly connected inside the sealing cover 104. The inner wall of the sealing bearing 108 is fixedly connected with a main rod 105. The bottom end of the main rod 105 is fixedly connected with a clamping block 109. Limiting columns 111 are fixedly connected to both sides of the inner wall of the sealing cover 104. A valve core 110 is arranged inside the quick-opening valve body 1. A motor 113 is fixedly installed on one side of the inner wall of the valve core 110. The output end of the motor 113 is fixedly connected with a bidirectional threaded lead screw 112. Two slide blocks 114 are threadedly connected to the outer surface of the bidirectional threaded lead screw 112. One side of the two slide blocks 114 is fixedly connected with an arc-shaped plate 115. Two connecting pipes 101 are fixedly embedded inside the quick-opening valve body 1. A rotating handle 106 is fixedly connected to the outer surface of the main rod 105.

[0032] In this embodiment, first, the flange 102 on one side of the connecting pipe 101 is installed on the pipe for HVAC heating. When the valve core 110 needs to be replaced, the staff removes the sealing cover 104 with a plurality of bolts 103, then places the new valve core 110 in the quick-opening valve body 1. Subsequently, the external power supply of the motor 113 is turned on, and the motor 113 is started by using the controller. The output end of the motor 113 starts to drive the bidirectional threaded rod 112 to rotate forward. Through the continuous forward rotation of the bidirectional threaded rod 112, the two sliders 114 on the outer surface of the bidirectional threaded rod 112 start to move towards the clamping block 109 at the bottom of the main rod 105, and the raised blocks on the inner walls of the two arc-shaped plates 115 are buckled into the grooves in the inner wall of the clamping block 109, and the clamping block 109 is firmly clamped. When the valve core 110 to be replaced needs to be disassembled, the staff uses the controller to reverse the motor 113 to release the clamping block 109 by the two arc-shaped plates 115, thereby completing the disassembly of the entire valve core 110, so as to achieve convenient replacement of the valve core, rapid disassembly and assembly of the valve core, ensure the overall maintenance effect, and improve the replacement efficiency of the valve core.

[0033] Embodiment 2, as Figures 1 - 4 shown, a circular gear 2 is fixedly sleeved on the outer surface of the main rod 105. A heightening block 201 is fixedly connected to the top of the sealing cover 104 near the edge. An electric telescopic rod 202 is fixedly installed on the top of the heightening block 201. The output end of the electric telescopic rod 202 is fixedly connected to a long rack 203. Flanges 102 are fixedly connected to the outer surfaces of the two connecting pipes 101. One side of the long rack 203 meshes with the outer surface of the circular gear 2.

[0034] In this embodiment, after the valve core 110 is installed, in order to facilitate the rotation of the entire main rod 105, the staff first turns on the external power supply of the electric telescopic rod 202 on the top of the heightening block 201, starts the electric telescopic rod 202 by using the controller. The output end of the electric telescopic rod 202 gradually pushes the long rack 203 to move horizontally, and drives the entire circular gear 2 to rotate. As the circular gear 2 rotates, the entire main rod 105 also rotates accordingly, and drives the clamping block 109 at the bottom of the main rod 105 to rotate, thereby completing the use of the valve core 110, so as to achieve convenient opening and closing of the cock, which is very simple, time-saving and labor-saving, and improves the practicability of the quick-opening valve.

[0035] Working principle: When in use, first install the flange 102 on one side of the connecting pipe 101 on the pipe for HVAC heating that is required. When the valve core 110 needs to be replaced, the staff removes the sealing cover 104 with a plurality of bolts 103, then places the new valve core 110 in the quick-opening valve body 1. Subsequently, turn on the external power supply of the motor 113 and start the motor 113 using the controller. The output end of the motor 113 starts to drive the bidirectional threaded screw rod 112 to rotate forward. Through the continuous forward rotation of the bidirectional threaded screw rod 112, the two sliders 114 on the outer surface of the bidirectional threaded screw rod 112 start to move towards the clamping block 109 at the bottom of the main rod 105, and the raised blocks on the inner walls of the two arc-shaped plates 115 are buckled into the grooves in the inner wall of the clamping block 109, firmly clamping the clamping block 109. When the valve core 110 to be replaced needs to be disassembled, the staff uses the controller to reverse the motor 113, so that the two arc-shaped plates 115 release the clamping block 109, thereby completing the disassembly of the entire valve core 110, so as to achieve the convenience of replacing the valve core, the quick disassembly and assembly of the valve core, ensuring the overall maintenance effect, improving the replacement efficiency of the valve core. And when the valve core 110 is installed, in order to facilitate the rotation of the entire main rod 105, the staff first turns on the external power supply of the electric telescopic rod 202 at the top of the heightening block 201, starts the electric telescopic rod 202 using the controller. The output end of the electric telescopic rod 202 gradually pushes the long rack 203 to move horizontally, driving the entire circular gear 2 to rotate. As the circular gear 2 rotates, the entire main rod 105 also rotates accordingly, driving the clamping block 109 at the bottom of the main rod 105 to rotate, thereby completing the use of the valve core 110, so as to achieve the convenience of better opening and closing the cock, which is very simple, time-saving and labor-saving, and improves the practicability of the quick-opening valve.
