Abstract
Claims
1. A reset spool, characterized by: The device includes a housing (1), a base (2), a stationary valve plate (3), a moving valve plate (4), a valve stem (5), and a reset component. The housing (1) is connected to the base (2). The stationary valve plate (3) is circumferentially fixed on the base (2). The moving valve plate (4) is rotatably mounted on the stationary valve plate (3). The valve stem (5) is rotatably mounted inside the housing (1) and can drive the moving valve plate (4) to rotate. The reset component is used to reset the valve stem (5) and drive the moving valve plate (4) to reset.
2. A reset valve core according to claim 1, characterised in that: The reset component includes a torsion spring (6), one end of which is relatively stable or connected to the housing (1), and the other end of which is relatively stable or connected to the valve stem (5).
3. A reset valve core according to claim 2, wherein: A limiting groove 1 (7) is provided on the outer shell (1), and one end of the torsion spring (6) is located in the limiting groove 1 (7). The limiting groove 1 (7) is used to limit one end of the torsion spring (6). A limiting groove 2 (8) is provided on the valve stem (5), and the other end of the torsion spring (6) is located in the limiting groove 2 (8). The limiting groove 2 (8) is used to limit the other end of the torsion spring (6).
4. A valve core according to any one of claims 1 or 2 or 3, characterised in that: The valve core also includes a locking element (9) for locking the valve stem (5).
5. A reset valve core according to claim 4, wherein: The valve stem (5) is provided with a handwheel (10) at its end. The handwheel (10) has a clearance hole (11) on its side wall. The locking member (9) includes a pressing block (91) and a return spring (92). The pressing block (91) slides through the clearance hole (11). The return spring (92) is disposed between the pressing block (91) and the handwheel (10). The pressing block (91) has a limiting part (911). The pressing block (91) can slide to cooperate with the handwheel (10) to squeeze the return spring (92) and cause the limiting part (911) to disengage from the limiting structure that limits its circumference.
6. A reset valve core according to any one of claims 1, 2 or 3, wherein: The base (2) is made of elastic material and is snapped into the outer shell (1).
7. A valve core according to any one of claims 1, 2 or 3, wherein: The inner wall of the outer shell (1) is provided with a positioning protrusion (12), the side wall of the base (2) is provided with a positioning groove (13) that is adapted to the positioning protrusion (12), and the outer wall of the static valve plate (3) is provided with a positioning groove (14) that is adapted to the positioning protrusion (12). The positioning protrusion (12) is located in the positioning groove (13) and the positioning groove (14).
8. A reset valve core according to claim 7, characterised in that: The end of the positioning protrusion (12) extends to the outside of the housing (1) to form a positioning foot (15) eccentric to the housing (1).
9. A reset valve core according to claim 6, wherein: The base (2) has two through holes (16), the stationary valve plate (3) has two flow channel holes (17) corresponding to the two through holes (16), and the moving valve plate (4) has a connecting groove (18) on the surface of the stationary valve plate (3). The connecting groove (18) can connect the two flow channel holes (17), and the moving valve plate (4) can separate the two flow channel holes (17).
10. A reset valve core according to claim 9, characterized in that: The base (2) has at least two annular protrusions (19) on its surface, which surround the two through holes (16) respectively. The base (2) has at least two annular protrusions (20) on its surface opposite to the stationary valve plate (3), which surround the two through holes (16) and the two flow channel holes (17) respectively.
