Fig. 3 is the structural representation of the hand control valve of the embodiment of the invention.As shown in Figure 3, similar with hand control valve of the prior art, hand control valve of the present invention comprises Joystick 301 and valve body 302, and Joystick 301 is rotationally connected by valve rod 303 1 ends of screw thread and valve body 302.The bottom of valve body 302 has valve pocket 304, and valve pocket 304 can be communicated with the supplying tube 306 and the output tube 307 of hand control valve external communications.And also have a piston 305 in the valve pocket 304, this piston 305 is fixed in valve rod 303 the other end of Joystick 301 dorsad.
When Spin Control handle 301 vertically moves downward to default closed position and by thread belt ovable valve stem 303 and piston 305, until piston 305 being communicated with at valve pocket 304 inner blocking-up supplying tubes 306 and output tube 307 and valve pocket 304, can realize closing of output tube 307, the gas that enters supplying tube 306 this moment can't be through output tube 307 outputs, and hand control valve is in closed condition.
When Spin Control handle 301 to default enable possition and drive valve rod 303 and piston 305 vertically moves upward, the opening that is communicated with supplying tube 306 and output tube 307 away from valve pocket 304 until piston 305, make valve pocket 304 and supplying tube 306 and output tube 307 recover connected state, can realize the unlatching of output tube 307, gas by supplying tube 306 enter valve pocket 304, by output tube 307 output, at this moment, hand control valve is on state.
Different with this hand control valve of the prior art is, has the cavity 311 that extends along valve rod 303 radial direction in the Joystick 301 of hand control valve of the present invention, is equipped with the locking bolt 308 that can move in the radial direction at valve rod 303 in the cavity 311; Wherein, cavity 311 is along valve rod 303 radial direction and towards an end of valve rod 303, have opening in Joystick 301 and tapped hole that valve rod 303 is rotationally connected, promptly be communicated with this tapped hole, locking bolt 308 can stretch out and stretches in the tapped hole from cavity 311 by this opening;
The end that valve rod 303 is connected with Joystick 301 have can or plug blocking-up and when keeping being communicated with of valve pocket 304 and supplying tube 306 and output tube 307, for locking bolt 308 along the insertion of valve rod 303 radial direction and the hole 313 of extracting.
Like this, locking bolt 308 can move along valve rod 303 radial direction in cavity 311 under the effect of external force, for example the operator inwardly promotes to lock bolt 308 or outwards spurs locking bolt 308 along valve rod 303 radial direction along valve rod 303 radial direction, can realize being inserted in the hole 313 or extracts in hole 313.
In the present embodiment, can be inserted in the hole 313 by using gases promotion locking bolt 308, therefore hand control valve of the present invention also comprises gas line 309 and the control valve 310 that is used for 309 conductings of control gaseous pipeline and cuts out, wherein control valve 310 can be manually operated valve, solenoid valve or pneumatic valve etc., gas line 309 is communicated with cavity 311 from controlling handle 301 outsides, the locking bolt 308 that the gas of importing by gas line 309 can promote in the cavity 311 inwardly moves along valve rod 303 radial direction, until locking bolt 308 patchholes 313.
In the present embodiment, can also use for example elastic element 312 pullings of the reset condition recovered of spring, shell fragment to lock bolts 208 and in hole 313, extract.Specifically, one end of the valve rod dorsad 303 of locking bolt 308 connects for example elastic element 312 of the reset condition recovered of spring, shell fragment, one end of elastic element 312 links to each other with locking bolt 308, and the other end is fixed in the side inwall that Joystick 301 is communicated with gas line 309.
Like this, elastic element 312 in locking bolt 308 patchholes 313 time pulling locking bolt 308 in cavity 311, outwards move along valve rod 303 radial direction, extract hole 313 until locking bolt 308.Wherein, in valve rod 303 length in the radial direction, when promptly not feeding gas in cavity 311, locking bolt 308 is contained in the cavity 311 the length sum of the original length of elastic element 312 and locking bolt 308 fully smaller or equal to cavity 311.
In the present embodiment, the set-up mode in hole 313 can have multiple.
For example, if piston blocking-up and when keeping described connection, Joystick 301 is 180 ° with respect to the rotation angle difference of valve rod 303, then the other end of this valve rod 303 is run through in hole 313 in the radial direction at valve rod 303, and an end in this hole 313 is for can be when being communicated with of piston 305 blocking-up valve pockets 304 and supplying tube 306 and output tube 307, insert and extract along valve rod 303 radial direction for locking bolt 308, the other end in this hole 313 can be when piston 305 keeps being communicated with of valve pockets 304 and supplying tube 306 and output tube 307, insert and extract along valve rod 303 radial direction for locking bolt 308.
Certainly, hand control valve of the present invention is not limited in this kind situation, for example, when piston 305 blocking-up with when keeping being communicated with of valve pocket 304 and supplying tube 306 and output tube 307, when Joystick 301 is 90 ° with respect to the rotation angle of valve rod 303,303 of valve rods have two mutually orthogonal holes of axis; Perhaps, when piston 305 blocking-up with when keeping being communicated with of valve pocket 304 and supplying tube 306 and output tube 307, during greater than 360 °, then 303 of valve rods have axis two holes of different surface beeline each other with respect to the rotation angle of valve rod 303 for Joystick 301 during with respect to valve rod 303 needs rotation multi-turn, Joystick 301.
Fig. 4 is the schematic representation that I partly is in first state among Fig. 3.As shown in Figure 4, owing to do not feed gas in the cavity 311, therefore, elastic element 312 is in unstretched state, and locking bolt 308 is contained in the cavity 311 fully.At this moment, non-locking between Joystick 301 and the valve rod 303, Joystick 301 can be rotated with respect to valve rod 303.
For the current state of this hand control valve of preventing to cause owing to misoperation is changed, the current state of lockable hand control valve, as shown in Figure 3, by control valve 310 with gas line 309 conductings, gas in the gas line 309 feeds in the cavity 311 at this moment, makes locking bolt 308 be in second state.Fig. 5 is the schematic representation that I partly is in second state among Fig. 3.As shown in Figure 5, feed gas in the cavity 311, then locking bolt 308 inwardly moves in the promotion lower edge of gas valve rod 303 radial direction, this moment elastic element 312 tensile elongation with the locking bolt 308 the length sum greater than cavity 311 in valve rod 303 length in the radial direction, and in valve rod 303 length in the radial direction, an end that promptly locks the elastic element dorsad 312 of bolt 308 inserts in the through hole 313 tensile elongation of elastic element 312 less than cavity 311.At this moment, the other end is contained in the cavity 311 because an end of locking bolt 308 is contained in the through hole 313, therefore, locked between Joystick 301 and the valve rod 303, Joystick 301 can't be with respect to valve rod 303 rotations, this moment, Joystick 301 can't be rotated, then the reformed situation of the current state of this hand control valve that can not take place to cause owing to misoperation.
When needs change the current state of this hand control valve, then need at first to remove locking, as shown in Figure 3, gas line 309 is closed by control valve 310 to current state, gas in the gas line 309 can not feed in the cavity 311 at this moment, and locking bolt 308 is in the third state.Fig. 6 is the schematic representation that I partly is in the third state among Fig. 3.As shown in Figure 6, because the gas in the gas line 309 can not feed in the cavity 311, then gas disappears to the thrust of locking bolt 308, lock bolt 308 and outwards move in the tensile force effect lower edge of elastic element 312 valve rod 303 radial direction this moment, recover original length until elastic element 312, locking bolt 308 is returned to first state as shown in Figure 4, lock bolt 308 and be contained in fully in the cavity 311 this moment, lock state between Joystick 301 and the valve rod 303 is removed, Joystick 301 can be rotated with respect to valve rod 303, and then the operator can change the state of this hand control valve by Spin Control handle 301.
In the foregoing description, in the Joystick of hand control valve, have the cavity that extends along the valve rod radial direction, being equipped with in this cavity can be at the mobile in the radial direction bolt of valve rod; And the valve rod that an end and piston are fixedly linked, its the other end is connected by threads turn with Joystick, and have can be when piston be blocked valve pocket and is communicated with supplying tube and output tube for described bolt along the valve rod radial direction insert and when the valve pocket that piston keeps is communicated with supplying tube and output tube the described bolt of confession along hole that the valve rod radial direction is extracted.Like this, if described bolt is inserted in the hole of the valve rod the other end, then Joystick can't rotate with respect to valve rod, thereby can't move by thread belt ovable valve stem and piston, and then can lock the current state of hand control valve, and make the control action that changes the hand control valve current state become and unlock and two steps of Spin Control handle, greatly reduce the probability of happening of misoperation, misoperation be can prevent effectively, and the accuracy and the Security of operation improved hand control valve.
