Abstract

The utility model relates to a liquefied gas switch with a lock, which is provided with a whole lock composed of a lock body (5), a lock core (6) and a rotary handle (7). The lock core (6) is connected with a rotary valve (4), and the whole lock is fixed to a switch body (1) to form a whole switch. The lock core (6) is used for controlling the rotating position of the rotary valve (4) in order to obtain the aim of controlling the switch to be switched on or off.

Description

Liquefied gas swtich with lock

The utility model belongs to a kind of improved Liquefied gas swtich, is widely used in the delivery line or container of various liquid or gas.

The Liquefied gas swtich that uses all is made up of stop valve, housing and handle with sleeve at present, come controlling liquid or gas flow or end by handle with sleeve, but do not have lock function, can not utilize switch directly the use of liquid or gas to be controlled, need install special-purpose locking device in addition additional.

The purpose of this utility model is to provide a kind of Liquefied gas swtich with lock, and this novel Liquefied gas swtich can not arbitrarily be opened or closed switch by the pivotal position of locking device control switch handle with sleeve, can overcome the deficiency of existing such switch.

For ease of explanation, with the motorcycle tank fuel tap is example, technical solutions of the utility model are as follows: it is by Switch main body ［ 1 ］, handle with sleeve ［ 7 ］, lock body ［ 5 ］, lock core ［ 6 ］, rotary valve ［ 4 ］, oil strain cup ［ 14 ］ is installed nut ［ 19 ］, ［ 20 ］ and main oil pipe ［ 9 ］, is equipped with oily chimney filter compositions such as ［ 15 ］.Feature is that its handle with sleeve ［ 7 ］ is fixed together with lock core ［ 6 ］, forms lock integral body with lock body ［ 5 ］, and lock core ［ 6 ］ is directly controlled the rotation of rotary valve ［ 4 ］.

The utility model is simple in structure, and is reasonable in design, and under lock condition, the handle with sleeve of switch ［ 7 ］ can not rotate, thereby rotary valve ［ 4 ］ can not be rotated, and reaches the purpose of control switch.

Now the utility model is described in further detail in conjunction with the accompanying drawings.

Fig. 1 is the utility model structural drawing.

With reference to Fig. 1, the utility model is by lock body ［ 5 ］, lock core ［ 6 ］, it is whole that handle with sleeve ［ 7 ］ is formed lock, connect with rotary valve ［ 4 ］ by lock core ［ 6 ］, behind the insertion key, lock core ［ 6 ］ can rotate with handle with sleeve ［ 7 ］, thereby make rotary valve ［ 4 ］ rotate the purpose that makes switch reach conducting or end.After extracting key out, lock core ［ 6 ］ can not rotate, and rotary valve ［ 4 ］ can not be rotated, and makes switch conduction or the position of ending can not be changed, and reaches the purpose of control switch.

Among Fig. 1, ［ 8 ］ are locking plate, lock core ［ 6 ］ is played the role of positioning, and the main oil pipe of ［ 9 ］, ［ 15 ］ are standby oily chimney filter.After main oil pipe oil has flowed, handle with sleeve ［ 7 ］ is turned to the spare space connect oil duct fully, can continue fuel feeding, ［ 10 ］ are fixed on the Switch main body ［ 1 ］ by steel wire retaining river ［ 17 ］ for nut is installed, and connect with fuel tank.When rotary valve is positioned at Fig. 1 position, oil in the fuel tank is flowed in the oil duct on Switch main body ［ 1 ］ top by main oil pipe, main oil gallery in rotary valve ［ 4 ］ flows into the oil duct of Switch main body ［ 1 ］ bottom, flow into again in the oil strain cup ［ 14 ］, after oil is full of oil strain cup ［ 14 ］, after filter screen ［ 12 ］ filters, flows into oil outlet ［ 21 ］ and flow out.Sealing river ［ 11 ］, ［ 13 ］, ［ 16 ］ seal, and prevent that oil leakage from going out.Handle with sleeve ［ 7 ］ is installed screw ［ 19 ］ handle with sleeve ［ 7 ］ is fixed on the lock core ［ 6 ］, and lock body retaining screw ［ 20 ］ is fixed together lock body ［ 5 ］ and Switch main body ［ 1 ］, forms switch integral body.
