Description
Technical field
The utility model relates to valve technology field, relates to or rather a kind of Anti-theft ball valve.
Background technique
At oil field shaft mouth, oil tank, gathering station and oil and gas pipes system, petroleum chemical industry extensive use ball valve, people are conventionally so that flowing of the such valve control liquids and gases of ball valve to be set, and these ball valve majorities can freely openable.In the needs to management, the ball valve of some position is forbidden random opening and closing, as the total lock of pipeline etc., need to be on ball valve with locking device with prevent other people without authorization Open valve steal draining gas.In order to reach antitheft effect, on market, there are various Anti-theft ball valves, some Anti-theft ball valve structure is more complicated, uses inconvenient; And some Anti-theft ball valve structure is simpler, anti-theft effect is not good.
License notification number is that the utility model patent of CN202469200U discloses a kind of locking Anti-theft ball valve, this Anti-theft ball valve comprises lock tube, lock tube is located between stem bearing and valve rod and is fixed on by fixing pin on the inside circumference wall of stem bearing, is also provided with the locking closure by key control between lock tube and valve rod.Locking closure structure is also more complicated, comprises displacement pin, stop pin and coil tension spring.When use, administrative staff control the locking of ball valve by key, and while use, key is accepted, and reaches antitheft effect by this kind of mode.This kind of Anti-theft ball valve complex structure, in the process using, key loss is just not easy to open ball valve again, makes troubles to user.
Model utility content
The technical problems to be solved in the utility model is, a kind of Anti-theft ball valve of simple in structure, easy to use and good anti-theft effect is provided.
Technical solution of the present utility model is, a kind of Anti-theft ball valve with following structure is provided, and comprises valve body, joint, valve rod, spool and handle; Described spool is located in described valve body; Described joint is connected on described valve body; The upper end of described valve body is provided with the protruding neck of hollow, and described valve rod is located in described protruding neck; Described handle is connected on the upper end of described valve rod and this taper knob is combined in outside the upper end of described protruding neck; The lower end of described valve rod connects described spool, on the up and down upper end that is connected to described valve rod of described handle; Between described protruding neck upper end and handle, be provided with press down handle under ball valve closed condition time when handle is carried out upper and lower spacing longitudinal magnetic lock device and press down handle under ball valve closed condition handle is carried out to circumferentially spacing peripheral locking device.
Adopt after above structure, Anti-theft ball valve of the present utility model, compared with prior art, has the following advantages:
Because Anti-theft ball valve of the present utility model comprises longitudinal magnetic lock device and peripheral locking device, press down handle under ball valve closed condition time, longitudinally locking handle of described longitudinal magnetic lock device, peripheral locking device is locking handle circumferentially, simple in structure, easy to use, and anti-theft effect is better.While not needing to lock, as long as use specialized opener (instrument of actual carry magnet can be also a magnet) to carry out release to longitudinal magnetic lock device, handle will get on by bullet, can rotate freely to control again ball valve after handle bullet gets on, and release is also very convenient.
As a kind of improvement of the present utility model, the middle part of described handle is provided with mounting hole; Described handle is linked in by mounting hole outside the upper end of described valve rod; In described mounting hole, be provided with anti-dismantle screw, the lower end of described anti-dismantle screw is connected on the upper end of described valve rod; The inner side of described mounting hole is provided with along the bulge loop of mounting hole radial projection; It is outer and spacing between the nut of described anti-dismantle screw and the upper end of valve rod that described bulge loop is linked in the screw rod of anti-dismantle screw; Between described handle and protruding neck upper end, be also provided with return spring.Adopt after this kind of structure, described handle capable of being is up and down, and the up and down space of handle just, the space reserving between nut and the upper end of valve rod, return spring can make handle return, simple in structure, reliable.
As another kind of improvement of the present utility model, described longitudinal magnetic lock device comprises strong magnetic pin, spring, be laterally located at the pin-and-hole on the periphery wall of protruding neck upper end and be laterally located at the spacing counterbore on handle madial wall; Described strong magnetic pin is located in described pin-and-hole, between described spring is located at the bottom of described the inner of strong magnetic pin and the hole of pin-and-hole; The outer end of the strong magnetic pin described in press down handle under ball valve closed condition time can be held in described spacing counterbore.Adopt after this kind of structure, when make pin-and-hole align with spacing counterbore by lower handle, be subject to the effect of spring force, the outer end of described strong magnetic pin will be held in spacing counterbore, and so just longitudinal locking handle also can make handle can not rotate simultaneously; While needing release, as long as use the specialized opener of carry magnet, the principle of utilizing two like magnetic poles attract each other, the opposite sex to repel each other, exits strong magnetic pin from spacing counterbore and just can make the handle initial position that upwards rebounds, simple in structure, very easy to use.
Also have a kind of improvement as of the present utility model, described peripheral locking device comprises the projection on the upper end of being located at described protruding neck and is located at the groove on the inner side of described handle, and the position of described groove is corresponding with the position of described projection; Described projection can be contained in described groove.Adopt after this kind of structure, in the time pressing lower handle, described projection just can be held in groove, so just can further limit handle in circumferential activity, makes the structure of Anti-theft ball valve more reliable.
Also have one to improve as of the present utility model, the both sides of the upper end of described protruding neck are respectively equipped with lug; Described pin-and-hole and projection are located at respectively on two described lugs.Adopt after this kind of structure, described lug plays the effect of gaining in strength to protruding neck, makes the structure of ball valve more reliable.
