Abstract
The utility model relates to an automatic safety guarding gas delivery hose, which comprises a hose body part and a safety guarding part which are connected mutually, wherein, the hose body part and the safety guarding part are provided with connectors on one end. The safety guarding part comprises a hose body, a sealing member, and a positioning seat, wherein, the positioning seat is fixed inside the hose body. One end of the sealing member is connected with the positioning seat by a spring, and the other end of the sealing member is mated with a sealing face of the hose body. A sliding block matched with the sealing member is arranged in the hose body on the other side of the sealing face. A sliding magnetic ring is arranged outside the hose body opposite to the sliding block. The automatic safety guarding gas delivery hose overcomes the drawbacks of complex structure, inconvenient resetting operation and lower reliability of the common safety guarding fuel gas hose in the prior art. The utility model can greatly reduce the safety accidents caused by shedding, ageing crack and fracture of gas delivery leather hose by the specific design. The utility model has the advantages of simple structure, convenient assembly, long service, energy saving, environment protection and strong reliability.
Description
Affiliated technical field
The utility model relates to a kind of automatic protecting air hose.
Background technique
At present, the use popularity rate of China resident family combustion gas is more and more higher, combustion gas brings numerous simultaneously also dangerous constantly easily securities of the lives and property of people to people, now because various security incidents such as the gas leakage that the use combustion gas causes, poisoning, fire, blast are also increasing.Although on market, also occurred some security personnel's products of developing out at flexible pipe safety at present, but these products all exist the defective that can not be ignored: what have has introduced solenoid valve in structure, its structure is complexity but also impracticable not only, in case do not had electricity will lose all protection functions; What have only can report to the police when the gas leakage accident takes place and can not cut off source of the gas automatically.00234322.3 number Chinese patent provides a kind of " automatic protecting gas hose ", in use also there is following defective in it: the one, introduced thin security personnel's spring as hair, so thin spring, behind the expanding-contracting action that certain number of times takes place, be easy to take place deformation, spring force and also bigger change can take place, thereby influence security personnel's performance of product greatly, even lose whole protection functions.The 2nd, the reset operation inconvenience needs very big jacking force could realize resetting.
Summary of the invention
In order to overcome common security personnel's gas hose complex structure in the prior art, reset operation inconvenience, problem that reliability is lower, the utility model provides a kind of automatic protecting air hose, this automatic protecting air hose simple in structure, reset operation convenient, safe and reliable, the effect that has energy-saving and environmental protection concurrently.
The technological scheme that its technical problem that solves the utility model adopts is: comprise interconnective tube body and security department, one end of tube body and security department is provided with connecting head, security department comprises body, Sealing and positioning seat, positioning seat is fixed in the body, one end of Sealing links to each other with positioning seat by spring, the other end matches with the sealing surface of body, is provided with the slide block that matches with Sealing in the body of sealing surface opposite side, the outer setting of the body slip magnet ring relative with slide block.
Slide block is " T " font, and Sealing is a ball sealer.
One side of slip magnet ring is provided with Returnning spring.
The pneumatic tube two ends of tube body are withheld by the bag sheet and are connected on the body, connecting head is made of rubber interface cover, intermediate plate and locking nut, rubber interface cover sticks on the body, and intermediate plate and locking nut are arranged on the rubber interface and overlap an end, and locking nut clamps rubber interface cover by intermediate plate.
The utility model is by above-mentioned specific design, can significantly reduce that the gas transmission leather hose comes off because of taking place when using combustion gas, aging cracking, the security incident of breaking etc. and to cause, and do not need any external force and power supply supply, also can cut off source of the gas immediately automatically even trickle gas leakage takes place, have the advantage of simple in structure, easy to assembly, long service life, energy-saving and environmental protection, good reliability in gas transmission leather hose (pipeline) section.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises interconnective tube body 1 and security department 2, pneumatic tube 12 two ends of tube body 1 are withheld by bag sheet 13 and are connected on the body 4, one end of tube body 1 and security department 2 is provided with connecting head 3, connecting head 3 is made of rubber interface cover 14, intermediate plate 15 and locking nut 16, rubber interface cover 14 sticks on the body 4, and intermediate plate 15 and locking nut 16 are arranged on the rubber interface and overlap 14 1 ends, and locking nut 16 clamps rubber interface cover 14 by intermediate plate 15.Security department comprises body 4, Sealing 5 and positioning seat 7, and positioning seat 7 is fixed in the body 4, and an end of Sealing 5 links to each other with positioning seat 7 by spring 6, and the other end matches with the sealing surface 8 of body 4, and Sealing 5 can be ball sealer.Be provided with the slide block 9 that matches with Sealing 5 in the body 4 of sealing surface 8 opposite sides, slide block 9 is for " T " font and can adopt the magnetic material manufacturing, and body 4 is outer to be provided with the slip magnet ring 10 relative with slide block 9, and a side of slip magnet ring 10 is provided with Returnning spring 11.Under user mode, connecting head 3 connects source of the gas and burner respectively, and when locking nut 16 precessions, each intermediate plate 15 can tighten up to the hose connection direction of axis line simultaneously, with the bore of rubber interface cover 14 press from both sides littler and littler, folder is tight more more, reaches the gastight purpose of firm connection easily.Under normal circumstances, combustion gas can be freely through the body 4 of security department 2, the pneumatic tube 12 last burners that arrive of tube body 1.Combustion gas can be by magnetic field magnetisation through magnetic slider 9 and slip magnet ring 10 positions the time, the combustion gas micel can be become more even by refinement atomizing, molecules align, thereby raising combustion efficiency, make fuel gas buring more abundant, reduced discharge of harmful gases effectively, both played energy saving, effect that again can the clean environment.If because of aging cracking takes place in gas transmission leather hose (pipeline), break, the gas leakage that comes off etc. and cause, then pneumatic tube 12 1 sides can because of enough gas make-up that can't obtain coming from body 4 in moment (owing to the restriction of Sealing 5, the peak rate of flow that flows into pneumatic tubes 12 from body 4 just also has only or is slightly larger than the required peak rate of flow of gas range normal combustion), the air pressure that is directed at pneumatic tube 12 1 sides is die-offed, and the air pressure in the body 4 does not almost have change in a flash at this, the pulling force that makes Sealing 5 overcome spring 6 moves rapidly and tightly is attached on the sealing surface 8 of body 4, thereby be implemented in the automatic source of the gas that cuts off of moment, reach the automatic protecting purpose.After finding and getting rid of the gas leakage accident, only with hand promotes slip magnet ring 10, slip magnet ring 10 drives magnetic slider 9 pushing tow Sealings 5, Sealing 5 and sealing surface 8 are broken away from, gas in the body 4 can enter pneumatic tube 12 rapidly, make the pneumatic tube 12 and the gas pressure of body 4 reach balance again, recover normal air feed again.
