When turning clockwise, switching knob 2 fully opens ball valve, and pawl bar 14 now is adjusted into the middle part of through hole 13, passed through
The limitation of arc groove 6 and limited block 7 on limiting plate 5 so that switching knob 2 can make 90 degree of rotation, band ovable valve stem 4 is in the same direction
Rotation, bidirectional ratchet 1201 is driven by the setting of valve rod 4 and bidirectional ratchet 1201 and the connection of valve rod 4 and spherical valve core 9
And spherical valve core 9 makees concentric clockwise rotation, now the entrance point 1001 of the internal channel 10 of spherical valve core 9 slowly with valve
The docking of charging aperture 101 of body 1 is communicated, and behind the position for being fully rotated into unlatching, pawl bar 14 is adjusted into the side of through hole 13, makes first
Pawl first 2301 is stuck in the tooth of bidirectional ratchet 1201, and bidirectional ratchet 1201 can not can make rotate counterclockwise, while valve rod 4, spherical
Valve element 9 and switching knob 2 reach self-locking effect all without convolution.Now fluid enters valve body 1 from the charging aperture 101 of valve body 1
It is interior, the runner charging aperture 301 of discharge pipe 3 is exited into from the discharging opening 102 of valve body 1, by the mistake at runner charging aperture 301
Filter screen 16, is filtered to the impurity in fluid, and the fluid after final filtration exits into pipeline from runner discharging opening 302.
During rotate counterclockwise switching knob 2, pawl bar 14 need to be first adjusted to the middle part of through hole 13, when switching knob 2 rotates
After being closed to ball valve, then pawl bar 14 is adjusted to make in the tooth of the first 2302 insertion bidirectional ratchet 1201 of the second pawl of double ended pawl 1202,
Reverse self-locking can be completed.
Embodiment two：As shown in Figure 5 and Figure 6, the embodiment of second of self-locking mechanism 12 is proposed, self-locking mechanism 12 includes
Ratchet and pawl, but ratchet is single direction ratchet 1203, and ratchet is single head ratchet 1204.
There is the roof of groove 20 and groove 20 elastic component 21, elastic component 21 is fixedly installed for the inside of switching knob 2
It may be selected to use spring, the other end of elastic component 21 is connected with the top of valve rod 4.The groove 20 of switching knob 2 is in cube and top
The gap of square valve rod 4 for being in coordinates, and limiting switching knob 2 can in the axial direction perform relative motion and circumferential upper unbiased with valve rod 4
Move.
Shown in reference picture 6 and Fig. 7, single direction ratchet 1203 is fixedly connected with the bottom of switching knob 2 by glue, is covered simultaneously
It is located on valve rod 4, switching knob 2 drives single direction ratchet 1203 to be rotated with valve rod 4 simultaneously, valve rod 4 drives spherical valve core 9
Rotate.In valve body 1 single head ratchet 1204, single head ratchet 1204 are integrally formed with relative to the sustained height of single direction ratchet 1203
With a monodactyle first 24, one end monodactyle first 24 of single head ratchet 1204 is inserted in the tooth of single direction ratchet 1203, the other end and valve
Body 1 is fixedly connected by screw.
Under normality during 21 non-stress of elastic component, single direction ratchet 1203 cooperates with single head ratchet 1204.When needs are opened
When opening ball valve, press switching knob 2 and make clockwise rotation, then drive single direction ratchet 1203 to move downward and single head ratchet
1204 separate, and now single direction ratchet 1203 can make 0 degree to 90 degree clockwise of rotary motion with valve rod 4, while valve rod 4 drives
Spherical valve core 9 makees clockwise rotation so that the charging of the entrance point 1001 of the internal channel 10 of spherical valve core 9 slowly with valve body 1
Mouthfuls 101 docking are communicated, and are rotated to appropriate location so that Fluid Volume regulation is correct, are removed in the downward active force of switching knob 2,
Switching knob 2 rises with single direction ratchet 1203 in the presence of elastic component 21 resets so that the monodactyle first 24 of single head ratchet 1204 blocks
In the tooth of single direction ratchet 1203, single direction ratchet 1203 can not can make the rotation on any direction, Simultaneous Switching knob 2 and valve rod
4th, spherical valve core 9 reaches self-locking effect all without rotation.
When needing rotate counterclockwise switching knob 2 to adjust flow, switching knob 2 need to be first pressed down on, makes single direction ratchet
1203 separate with the monodactyle of single head ratchet 1204 first 24.Another mistake hour hands rotary switch button 2, makes valve rod 4 and the inverse time of spherical valve core 9
Pin rotates, and is adjusted to behind correct position, removes the active force for pressing down on switching knob 2, makes switch by the reset of elastic component 21
Knob 2 resets upwards with single direction ratchet 1203, and single direction ratchet 1203 coordinates with the pawl first 24 of single head ratchet 1204 again.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
