Abstract
The invention provides a flow control check valve. Existing check valves have the same characteristics that flow of liquid cannot be accurately controlled and only the operating direction of the liquid can be controlled. The flow control check valve comprises a valve body (1); both ends of the valve body are connected with connecting pipes (2) along the axial direction; a rotating shaft box (3) is arranged above the valve body along the radial direction; one end of a rotating shaft (5) in the rotating shaft box is positioned outside the valve body and is provided with a boss (4); the boss extends out of a positioning locking hole (6) positioned on the rotating shaft box; the other end of the rotating shaft is positioned inside the valve body and is hinged with a valve plate (7); the valve plate droops to be buckled on connecting pipe orifices when unidirectionally working; and the boss is connected with the positioning locking hole by screw threads. The flow control check valve is used as a valve.
Description
Technical field
The present invention relates to a kind of valve body, be specifically related to a kind of flow control one-way valve.
Background technique
One-way valve claims again safety check or check valve, is used for hydraulic system and prevents oil stream reverse flow, perhaps is used for pneumatic system and prevents the pressurized air reverse flow.Existing one-way valve mainly contains spring: liquid from bottom to top relies on the spring controlled flap of pressure jack-up, and after pressure disappeared, spring force was depressed flap, and sealing liquid flows backwards.Be usually used in the less safety check of latus rectum.2, gravity type: similar with spring, rely on the self gravitation sealing of flap, prevent from flowing backwards.3, rotary-open type: liquid is straight-through in valve body, relies on pressure to back down the rotation flap of a side, and after pressure lost, flap relied on the deadweight return, reverse fluid pressure sealing flap.4. plastic partition membrane type: shell and barrier film are plastics. and general shell is ABS, PE, PP, NYLON, the PC. barrier film has silicone, fluororesin etc.It is accurately to control the flow of liquid that existing one-way valve has common characteristics, can only control the direction of liquid operation.
Summary of the invention
The objective of the invention is provides a kind of flow control one-way valve for the problem of above-mentioned existence, can accurately control the flow of liquid, and using scope light is easy to use.
Above-mentioned purpose is achieved through the following technical solutions:
The flow control one-way valve, comprise valve body, described valve body two ends are connecting tubes vertically, the rotating shaft case is installed in described valve body top radially, it is outside and with boss that rotating shaft one end in the described rotating shaft case is positioned at valve body, described boss stretches out the position and lock hole that is positioned on the described rotating shaft case, the other end of described rotating shaft is positioned at valve inner and valve plate is hinged, hang down during described valve plate one-way only operation to be buckled in and take on the mouth, be threaded connection between described boss and the described location lockhole.
Described flow control one-way valve, described boss is 0-90 ° with respect to the angle of swing of described location lockhole.
Described flow control one-way valve, the diameter of described valve plate is greater than the external diameter of described adapter.
Beneficial effect:
1. the folding angle that can regulate valve plate by the rotation boss of the present invention, thereby the flow of control liquid, boss are threaded with locating to adopt between the lockhole, and be easy to adjust.
2. boss of the present invention is 0-90 ° with respect to the angle of swing of described location lockhole, and namely for being 0-90 °, flow adjustment range is large, and is applied widely with respect to the angle that radially can regulate of valve body for valve plate.
3. the diameter of valve plate of the present invention is greater than the external diameter of taking over, liquid reverse flow when effectively having avoided valve closing.。
Description of drawings
Fig. 1, structural representation of the present invention.
Among the figure:
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.
Embodiment 1:
As shown in Figure 1: flow control one-way valve of the present invention, comprise valve body 1, described valve body two ends are connecting tubes 2 vertically, rotating shaft case 3 is installed in described valve body top radially, it is outside and with boss 4 that rotating shaft 5 one ends in the described rotating shaft case are positioned at valve body, described boss stretches out the position and lock hole 6 that is positioned on the described rotating shaft case, the other end of described rotating shaft is positioned at valve inner and valve plate 7 is hinged, hang down during described valve plate one-way only operation to be buckled in and take on the mouth, be threaded connection between described boss and the described location lockhole.
Embodiment 2:
Described flow control one-way valve, described boss is 0-90 ° with respect to the angle of swing of described location lockhole.
Embodiment 3:
Described flow control one-way valve, the diameter of described valve plate is greater than the external diameter of described adapter.
By above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.Unaccomplished matter of the present invention belongs to those skilled in the art's common practise.
