The utility model whose valve body is of vibration prevention and is of impact prevention has the advantages of theft prevention and safety.

Description

Anti-overflow valve

The utility model relates to a kind of antitheft valve.

Valve has good adjustable conduction owing to it, and is widely used on the various pipelines such as various water pipes, gas pipe, fuel tube and car, ship fuel channel; And this valve causes tap water loss in vain, coal gas, the fuel gas pipeline leakage of public water pipe because can not control and management; Car, ship can not stop and promptly cut off motor fuel because valve can't locking, cause car, ship very easily by thief's short circuit ignition circuit turning circuit, engine on and car and boat are stolen.For safety, insurance, antitheft for the purpose of, a kind of lock cock valve is disclosed in Chinese patent CN2041380U, be characterized in the cock of general plug valve, a common spring lock core being set, and link together with cock, keying by key control cock valve, be mainly used in the community water supply tap, the piped gas switch and poisonous, easily reveal on the medium valve.In addition disclosing a kind of locking-able valve in Chinese patent CN2041756U, is the special valve with the key locking, is mainly used in oil, gas, water or other fluid and carries out the personal management, also can be used for motor vehicle, the control vehicle oil way.The shortcoming of above-mentioned two kinds of valves is when being subjected to mechanical external cause such as vibration, impact when valve body, but that the locking-valve core is hit is rotatable, and makes pipeline be in improper unobstructed or closed state, when being used for car, ship time, then easily causes valve closes to make engine misses owing to jolt.

The purpose of this utility model is for but a kind of antitheft valve that is combined locking, antitheft, safety, valve body vibration proof, impact by lock with valve is provided.

The purpose of this utility model can realize by following measure:

A kind of antitheft valve contains connection mouth, shell, valve body, spool, lock body, lock core etc.; Valve body is equipped with in the bottom of wall in the enclosure, is connected with connection mouth in the both sides of valve body, and spool is housed in valve body; Cover is inserted with lock core in the spool upper end, is enclosed within the outer lock body of lock core is fixed on shell by fixing frame inwall; Lock core sleeve in the end of lock body has positioning means; Both sides in the radial symmetric position of two mutual vertical center lines of positioning means inwall are equipped with positioning hole; On the outer wall of lock core bottom with positioning means be that an opposite position place, hole also is provided with pellet shot from a slingshot hole, location, location pellet shot from a slingshot and spring are housed therein.

The utility model has following advantage compared to existing technology:

1, the utility model adopts lock and valve to organically combine, but the locking pipeline is applicable to various pipelines and car, ship fuel channel.

2, the utility model adopts positioning means that lock core is located under key insertion state, when lock core rotated 90 °, positioning means was fixed lock core, and unlikely because mechanical factors such as vibration, impact rotate lock core, drive valve core rotation, and make passage be in improper locking or opening state; Avoided leakage, the loss of pipeline fluid, or when being used for car, ship oil circuit, made car, ship oil circuit unimpeded and stolen, or accident such as the motor that is in operation is flame-out suddenly.Concrete structure of the present utility model is provided by the following drawings:

The utility model also will 1,2 be implemented to be described in further detail in conjunction with the accompanying drawings:

With reference to Fig. 1,2, a kind of antitheft valve contains connection mouth (1), shell (2), valve body (3), spool (4), lock body (5), lock core (6) etc.; Valve body (3) is equipped with in bottom at shell (2) inwall, is connected with connection mouth (1) in the both sides of valve body (3), and spool (4) is housed in valve body (3); Cover is inserted with lock core (6) in spool (4) upper end, is enclosed within the outer lock body (5) of lock core (6) is fixed on shell (2) by fixing frame (8) inwall; Outside the lock core (6) of the end of lock body (8), be with positioning means (9); Both sides in the radial symmetric position of two mutual vertical center lines of positioning means (9) inwall are equipped with positioning hole (13); On the outer wall of lock core (6) bottom with positioning means (9) be that opposite position place, a hole (13) also is provided with pellet shot from a slingshot hole (10), location, location pellet shot from a slingshot (12) and spring (11) are housed therein.

The utility model also can be used for solenoid valve, also anti-theft technique can be used for pump.

Claims

1, a kind of antitheft valve contains connection mouth (1), shell (2), valve body (3), spool (4), lock body (5), lock core (6) etc.; It is characterized in that valve body (3) being housed, be connected with connection mouth (1), spool (4) is housed in valve body (3) in the both sides of valve body (3) in the bottom of shell (2) inwall; Cover is inserted with lock core (6) in spool (4) upper end, is enclosed within the outer lock body (5) of lock core (6) is fixed on shell (2) by fixing frame (8) inwall; Outside the lock core (6) of the end of lock body (8), be with positioning means (9).
