Description

Interior conduit gas leakage and earthquake automatic controller

One, technical field

Disclosed interior conduit gas leakage of the utility model and earthquake automatic controller belong to technical field of valve control.What be specifically related to is the building gas pipe, service pipe, indoor pipe device that automatic controlling plumbing fixtures valve turn-offs when leakage and earthquake.

Two, background technique

About the safety device of building gas pipe, service pipe, indoor pipe anti-leak, protection against and mitigation of earthquake disasters, it more shows important, and is known together by people aspect protection against and mitigation of earthquake disasters and guarantee people living safety.The all autocontrol valves that occur have his own strong points, and its deficiency is also arranged.China Patent No.: 99250951.3 " the automatic pass gas wrench of building gas pipe, service pipe, indoor pipe earthquake, leakage " by name, its deficiency is: the wrench that closes gas automatically only depends on the potential energy effect of sense shake ball whereabouts to close pipeline, in addition, resetting of sense shake ball, wrench and valve handle supporting, be connected, aspect such as use need do some improvement.Technological scheme described in the utility model has all been done improvement, and its structure is more reasonable, and performance increases, and its reliability, practicability obviously strengthen.

Three, summary of the invention

Goal of the invention of the present utility model is to provide this improved interior conduit gas leakage and earthquake automatic controller to society, for the protection against and mitigation of earthquake disasters of society and people's life is done some contribution.

The technical solution of the utility model is such: this interior conduit gas leakage and earthquake automatic controller, it is by the gas leakage automatic control mechanism of valve of gas pipeline, the earthquake automatic control mechanism, the housing of resetting-mechanism and this automatic controller, mounting plate, supporting installation component package assembly forms, wherein: the earthquake automatic control mechanism comprises: the horizontal ball bearing of installing on sense shake ball and the mounting plate, the lever of falling sphere control, it is installed on the mounting plate by fulcrum, lever one end is the bucket-shaped falling sphere of being convenient to connect, the protruding tooth that the other end is the rotating disc on crozier and the valve handle becomes supporting lock-bit structure, and crozier-protruding dental structure is being controlled the lock-bit and the rotation of rotating disc.The gas leakage automatic control mechanism comprises: the pillar that puts in jack-up sense shake ball in the tumbler bearing central hole, pillar is packed in an end of heading lever, this lever is also installed onboard by its fulcrum, the other end of lever is connected with electromagnetic core, and electromagnet has pilot to be connected with the household gas leakage alarm and to control.Resetting-mechanism comprises: the stay cord that resets that sense shake ball binds, the other end of this stay cord is bound in outside the housing, also has the hand reset wrench on the valve of gas pipeline.The characteristics of this technology are: the rotating disc that is sleeved on the pipeline valve door handle is established the energy storage torsion spring that Shuttoff Valve is housed, when the rotating disc control valve is in the enable possition, the crozier locking of the controlled lever front end of the protruding tooth of the lock-bit on the rotating disc, when rotating disc rotates to valve when being in scram position under the energy storage torsion spring resets pulling, the limiting stopper that the protruding tooth of rotating disc is mounted on the plate limits.When earthquake arriving and earthquake reach fortification intensity, seismic signal will make sense shake ball tumble falling sphere control lever one end, the crozier of this lever the other end is freed from the protruding tooth of rotating disc, under the effect of energy storage torsion spring, rotating disc drives pipeline valve by valve handle and turn-offs, and makes protruding tooth touch the limiting stopper position.If the alarm of external household gas leakage is when predicting gas leakage and reaching alarm condition, alarm signal will be controlled the electromagnet action, by iron core and heading lever action, pillar jack-up sense shake ball is fallen on the falling sphere control lever, the crozier of the lever the other end is freed from the protruding tooth of rotating disc, discharge rotating disc, it is under the torque spring energy store effect, and its protruding tooth rotates to limiting stopper place shelves, just also drive the gas valve door handle, make valve be in the position of turn-offing pipeline.After through disasters such as earthquake or gas leakages, when needing this automatic controller to reset, at first by the household gas leakage alarm work, when alarm free, make the electromagnetic core adhesive through lead, and then the heading lever is restored balance, make the heading pillar fall back to tumbler bearing central reset position.Secondly by stopple, pulling ball rope beyond the Great Wall resets on the horizontal ball bearing sense shake ball, and the falling sphere lever is restored balance.Pass through valve wrench rotating valve at last from closing closed state to opening attitude, valve opening drives valve handle rotates rotating disc, make the protruding tooth of rotating disc rotate back into falling sphere lever crozier place from limiting stopper, crozier and protruding tooth interlock reset falling sphere lever and rotating disc simultaneously and lock.

Aforesaid interior conduit gas leakage and earthquake automatic controller, detailed technology characteristics also have: a, be provided with the limiting stopper of falling sphere control lever on mounting plate, be pressed down to the position of contact limiting stopper by falling sphere gravity when sense shake ball is fallen on the lever.B, rotating disc become movable installation with mounting plate, ball or bearing member are housed therebetween.The stay cord that resets on c, the sense shake ball is connected on the outer stopple of housing through the hole on the housing, pulls up stopper pulling rope ball is resetted, and then cover stopple, and the not only convenient sense shake of such structure ball resets but also guaranteed cleaning in this automatic controller.

Interior conduit gas leakage of the present utility model and earthquake automatic controller, can leak when reaching setting value and earthquake and reaching fortification intensity automatic control action mechanism at pipeline gas and turn-off pipeline valve, can prevent and avoid since the combustion gas of interior conduit (as coal gas, liquid gas) disasters such as leakage or earthquake initiation fire, it is the safety device that the resident family prevents and reduces natural disasters very to be needed, through improving, this automatic controller has installed the torque spring energy store mechanism of valve closing additional, reliability and fail-safe that autocontrol valve turn-offs have been improved, make its quality of product that raising arranged, this product is also in the structure of integral body in addition, install and done improvement, make it easy for installation, simple to operate, use reliably, so this device is the good product of preventing and reducing natural disasters that is worthy to be popularized.
