Preferably, the upper opening of the ball seat 202a is matched with the bottom ball part of the operation rod 203a, when the bottom ball part of the operation rod 203a is positioned at the upper part of the clamping part 202f in the ball seat 202a, the operation rod 203a and the ball seat 202a are in a soft connection and separation state, at this time, the upper opening space of the ball seat 202a can meet the rotation requirement of the bottom ball part of the operation rod 203a in the ball seat (as shown in fig. 8), namely, the operation rod 203a can not collide with the ball seat 202a or drive the ball seat 202a to move when stirring, and when the clamping groove 203b at the bottom of the operation rod 203a is clamped with the clamping part 202f, at this time, the operation rod 203a and the ball seat 202a are in a hard connection and clamping state, namely, the fluctuation of the operation rod 203a drives the ball seat 202a to move, namely, two connection states exist between the operation rod 203a and the ball seat 202a, so that a user can conveniently operate the multi-way control valve.
Further, the clamping piece 202f comprises a third spring 202f-1 arranged in a reserved cavity at the inner side of the lifting ring 202e, meanwhile, a clamping block 202f-2 is connected to the outer side of the third spring 202f-1, the clamping block 202f-2 is in a wedge-shaped arrangement, connection between the operating rod 203a and the ball seat 202a can be limited through clamping between the clamping block 202f-2 and the clamping groove 203b, meanwhile, the third spring 202f-1 can elastically support the clamping block 202f-2, and the clamping block 202f-2 can elastically stretch and retract relative to the lifting ring 202e, so that clamping and separation between the clamping block 202f-2 and the clamping groove 203b can be realized.
Furthermore, a wedge-shaped gap is still reserved on the bottom surface of the clamping block 202f-2, and the top end of the top piece 202d positioned at the bottom of the ball seat 202a is in wedge-shaped arrangement, so that the top piece 202d can be matched with the wedge-shaped gap on the bottom surface of the clamping block 202f-2, when the lifting ring 202e extrudes the second spring 202g to move downwards, the top end of the top piece 202d gradually contacts with the wedge-shaped gap on the bottom surface of the clamping block 202f-2 along with synchronous downward movement of the clamping block 202f-2, and further under the interaction of the top inclined surface of the top piece 202d and the bottom inclined surface of the clamping block 202f-2, the clamping block 202f-2 can shrink inwards and separate from the clamping groove 203b, and the purpose of controlling connection and locking between the clamping piece 202f and the operating rod 203a can be achieved through the arrangement of the top piece 202d, so that a control valve is convenient for a user to use.
When the slide valve 104 is specifically used, under the initial condition, the bottom ball head piece of the operating rod 203a is positioned at the upper part of the ball seat 202a, the operating rod 203a is connected with the connecting seat 202 through the first spring 204, at this moment, the operating rod 203a and the ball seat 202a are in a relatively movable state, namely, the stirring of the operating rod 203a can not influence the position of the ball seat 202a, when a user operates the slide valve 104, the operating rod 203a is firstly pressed down, at this moment, the bottom ball head piece of the operating rod 203a moves downwards, and the outer inclined surface of the clamping block 202f-2 is extruded through the bottom of the operating rod, so that the clamping block 202f-2 presses the third spring 202f-1, the clamping block 202b moves to the position of the same plane as the clamping block 202f-2 along with the continuous downward movement of the operating rod 203a, at this moment, the clamping block 202f-2 can be stretched into the clamping groove 203b under the action of the elasticity of the third spring 202f-1, at this moment, the ball seat 202a is clamped with the clamping groove 203b, at this moment, the ball seat 202a is integrally moved synchronously, further, through the hinging arrangement between the supporting piece 201 and the connecting seat 202 and the slide valve 104, the sliding seat 202 can be moved downwards, the position of the sliding block 202a is pushed down along the upper surface of the sliding block 202b, the upper surface of the sliding block 202b is pushed down along the upper surface of the sliding block 202b, and the sliding surface 202b is contacted with the upper surface 202b, and the top surface of the sliding block 202b, and the sliding plate 202b is gradually pushed down by the sliding surface 202b, and the sliding plate 202b, and the top surface is contacted with the sliding plate 202b, and the sliding surface 202b is gradually, and the top surface 202b is contacted with the sliding surface 202b is gradually, and the sliding surface 202b is gradually by the sliding surface and the sliding surface 202 and the sliding surface 202. Meanwhile, due to the difference of elastic coefficient and length parameter between the first spring 204 and the second spring 202g, the restoring speed of the first spring 204 is higher than that of the second spring 202g, so that the operating rod 203a can be restored in advance compared with the clamping piece 202f under the action of the elastic force of the first spring 204, the clamping piece 202f is difficult to be clamped with the clamping groove 203b again when the operating rod 203a pops up, namely, the ball head at the bottom of the operating rod 203a can be positioned at the upper part of the ball seat 202a again for free stirring, at the moment, stirring of the operating rod 203a does not drive the ball seat 202a to synchronously move, namely, the operating rod 203a and the ball seat 202a are in a complementary non-interference state, (refer to fig. 8), meanwhile, the operating rod 203a can be guided by the first spring 204 while the operating rod 203a can be elastically supported, so that the operating rod 203a and the ball seat 202a can be always positioned on the same axis, and the normal operation of the slide valve is prevented from being caused by the locking arrangement between the ball seat 202a and the operating rod 203a, and the slide valve 104 can be ensured, at the same time, the normal operation of the slide valve is prevented from being caused by the fact that the adjacent slide valve 203a is in normal operation and the normal operation.
Example 3

Further, the outer walls of the two sides of the ball seat 202a are provided with movable ports 202a-1 matched with the limiting rod 203d, the two ends of the limiting rod 203d extend to the outside of the movable ports 202a-1, meanwhile, the movable ports 202a-1 are semicircular straight slots at the two ends, space can be provided for horizontal deflection of the limiting rod 203d, and the movable ports 202a-1 can limit vertical movement of the limiting rod 203d so as to ensure stable swinging of the limiting rod 203 d.
Meanwhile, the guide cavity 203c is spirally twisted, and is formed by communicating an upper spiral cavity with a bottom vertical cavity, meanwhile, the width of the guide cavity 203c is matched with the diameter of the limit rod 203d, and then the guide cavity 203c moves up and down along with the operation rod 203a, so that the limit rod 203d can swing in the movable port 202a-1 under the pushing and guiding of the inner wall of the guide cavity 203c, the purpose of adjusting the relative position between the limit rod 203d and the limit ring 201c is achieved, and the purpose of limiting the rotation of the ball seat 202a through the connection of two ends of the limit rod 203d and the limit ring 201c is achieved.
Furthermore, the stop lever 203d and the stop collar 201c are cooperatively disposed, when the stop lever 203d is disposed in the vertical cavity of the guide cavity 203c, the operation rod 203a and the ball seat 202a are in an unclamped state, and meanwhile, the stop lever 203d is in a horizontal state, i.e. two ends of the stop lever can be respectively abutted against the inner spiral surfaces of the two stop collars 201c, and at this time, the inner side surfaces of the two stop collars 201c can be abutted against the stop lever 203d, so that under the combined action of opposite inclination trends of the inner side surfaces of the two stop collars 201c, the rotation of the stop lever 203d along with the ball seat 202a is limited, and the angle of the ball seat 202a after the operation is locked, so that the influence on the working position of the slide valve 104 caused by the re-rotation of the ball seat 202a is avoided;
