Air conditioning piping switch valve positioning structure improvement

The positioning structure of the air conditioning pipe switch valve of the present invention is improved, and the pivoting shaft for fixing the valve piece inside the switch valve body which is connected to the control pipe of the middle section of the air conditioning pipe is connected, and the fixing bolt which is directly fixed to the inner edge of the body is fixed at one end. , interlocking and assembling, so that when the valve piece is opened, it is completely locked and assembled, and when the pipeline is closed, it is reversely and slightly relaxed, and is assisted by the card edge of the inner edge cushion surface to achieve pivot opening and closing assembly use. Smooth and safe operation.

Conventional air conditioning piping, in order to meet the needs of actual use, in the middle or branch position of the pipeline, usually has a valve group for switching, for the flow opening and closing control, early pipe switch valve seat design, the interior usually has a seal The cushion surface of the ring column can be completely closed and leakproof, and the assembled pivot protrudes to the outside of one side to form a polygonal shaft end for remote control operation with a long arm-shaped dial. In order to prevent the slippage of the locking or opening position, a bolt for locking is provided on the other side of the gripping pivoting for the locking group to achieve the positioning operation of opening and closing the venting opening in the tube, the arm The design of the dial control, the inconvenience of its control, has always been inconvenient for the user, so the creator has set the improvement into a swingable control that can be easily controlled, such as the patent design of the announcement No. M391074, which effectively improves The dial-control operation in various environments can achieve the convenience of the force-applying operation. In the past, similar swing-type adjustment design, when the air-tube cross-sectional area is large, the airflow flowing through it is large and fast. , often subject to irregularities Then, the wind speed will cause unstable sloshing and vibration, which will cause the whole valve plate group structure to vibrate, so as to form a bad disturbance situation during the actual air supply flow, which not only affects the transmission rate, but also makes the user and the operator feel troubled. Then, because of the entire duct structure, usually the torus is It is made of thin metal sheet for bending and rolling. The actual joint rigidity is affected by the strong wind flapping vibration of the opposite valve. If it is not securely assembled, it is likely to be generated by pivoting. The looseness, breakage, deformation, etc. of the point position may cause a flow that is not smooth and is more likely to form a leak after a long-term or fixed deformation. The leakage caused by this deformation will affect the whole after the closure. The authenticity of the valve closure is serious. If it is new, it will not be easily overcome. Because of the lack of structural use caused by this actual use, the design and development of this creation will be improved.

In view of the above-mentioned air-conditioning piping opening and closing valve group under the actual use operation, the creators have doubts and omissions in the use of leak-proof use and actual use, and have been assembled and operated according to actual experience in actual design and assembly. It is easy to use and needs to be improved. Finally, the air-conditioning pipe switch valve positioning structure of this creation is improved. According to the side of the switch valve seat body, a fixing frame is provided for the penetrating group to extend into the bottom of the seat body, from the opposite side. After a fixing bolt is used to lock the pivot insertion end, the welding fixing position is applied, and the locking pivot plate is locked to the valve plate, and the adjustment is opened, and when the reverse rotation is loosely locked, the natural forming is closed. In the shape, when the valve plate is opened, the whole pivot shaft can fix the valve plate to be stable and fixed, effectively overcoming the practical defect of improving the instability of the conventional pivot opening.

The purpose of this creation is to assemble the pivot of the valve piece, except for the insertion side to be positioned by the fixed frame, and the inserted inner end is locked by a fixing bolt fixed to the inner surface of the valve seat body ring to make the pivot When the valve is opened, the shaft is indeed locked and assembled. When it is closed, it is assisted by the peripheral surface of the valve plate and the cushion surface of the inner edge of the valve plate, so that the pivot is closed after the slight release lock, and the pivot can still support the complete pivot. Closed engagement, to achieve the practical and safe purpose of air conditioning transport.
