Abstract

The utility model relates to a valve safe from thieves which comprises a valve body, a valve core, an operating member, etc. The valve safe from thieves is characterized in that the operating member of the valve is composed of a blocking device; through the matching of the lock core of the lock and the valve core, the purpose of theft protection of the fluid in motor vehicles such as a motorcycle, etc. and fluid storage tanks such as an oil depot, etc. can be obtained. The utility model has the advantages of compact structure, reasonable design and favorable effect.

Description

Valve safe from thiefs

The utility model relates to a kind of valve, a kind of Valve safe from thiefs of more specifically saying so.

Valve is the mechanical device of control fluid break-make, is made up of valve body, spool and functional unit etc. usually.Valve body links to each other with the controlled fluid loop, and functional unit is then directly controlled the break-make of fluid through spool.Common functional unit is manual or electronic screw mechanism, does not have thief-proof function.

The purpose of this utility model provides a kind of Valve safe from thiefs that can be applicable on the fluent material holding vessels such as motor vehicle fuel reserve tanks such as motorcycle and oil depot, and this valve can prevent that fluid is stolen from the mouth of pipe.

Functional unit of the present utility model is made up of a blocking device, can open or throttle down by the key rotary locking cylinder, thereby play thief-proof effect.

Fig. 1 is the sectional view of the utility model Valve safe from thiefs.

Fig. 2 is the B-B sectional view of the thief-proof valve of the utility model.

The utility model is described in further detail below in conjunction with Fig. 1.

As can be seen from Figure 1, valve of the present utility model is by spool ［ 1 ］, valve body ［ 2 ］ and functional unit--and lock ［ 3 ］ forms. Lock is a kind ofly to form (this kind lock Suzhou valve plant production is arranged) by lock core ［ 4 ］, lock body ［ 5 ］, billiards plate ［ 6 ］, positioning ejection reed ［ 7 ］. The boss ［ 12 ］ of lock by lock core ［ 4 ］ the bottom (see figure 2) that is connected with the groove on spool ［ 1 ］ top, the boss of lock core ［ 4 ］ bottom can be rectangle, triangle or quincunx, the groove that is complementary with above-mentioned shape is arranged at spool ［ 1 ］ top. When this connected mode just can make lock core ［ 4 ］ rotate, spool ［ 1 ］ also rotated thereupon, thereby played the effect of unlatching or valve-off. Billiards plate (6) is opened fluted rectangle stalloy for the centre, and its thickness is 1 millimeter. Its flute length has 5 kinds of different sizes, with the synthetic different lock core structure of sufficient amount of set of keys. Its groove width is suitable with key thickness. After key inserts lock core (4), namely pass the middle groove of each billiards plate (6) and by on the key different teeth groove each billiards plate (6) is pushed into reposition. If key is corresponding with lock core, none evagination of each billiards plate (6) then, otherwise evagination is namely arranged, and lock core (4) namely can not rotate in lock body (5), and valve namely can not open and close. This lock advantage is: but lockhole has the center of lock core, lock core outer surface not to have riveted holes and Anti-dismantling. The upper end flange of lock core ［ 4 ］ is by the interior step location of lock body ［ 5 ］, and lock core ［ 4 ］ bottom is then located by positioning ejection reed ［ 7 ］. On spool ［ 1 ］ top the arc shoulder is arranged, be embedded with zero type circle ［ 8 ］, zero type circle ［ 8 ］ is provided with non-return pad ［ 9 ］ and ripple spring ［ 10 ］, uses at last clamp nut ［ 11 ］ to compress, and makes valve seal.

The outlet port that above-mentioned valve is received holding vessel,, just can not from jar, draw liquid such as oil plant if do not open lock device.

Embodiment is as follows:

The valve length overall is 68 millimeters, and height is 53 millimeters, and maximum outside diameter is 30 millimeters, and latus rectum is 3 millimeters, and the inlet caliber is 10 millimeters, and the outlet caliber is 7 millimeters, and the lock body external diameter then is 25 millimeters.Used material is except that spool ［ 1 ］, valve body ［ 2 ］ and lock body ［ 5 ］ are that copper casting, zero type circle ［ 8 ］ are that all the other are versatile materials such as low carbon steel the 65Mn for oil resistant rubber, ripple spring ［ 10 ］.Present embodiment is applicable on the motorcycle tank.
