Abstract
The invention discloses a safety valve and particularly relates to a hydraulic safety valve comprising a crossed shell internally provided with a vertical channel and a horizontal channel, wherein the diameter of the vertical channel is larger than that of the horizontal channel; the shell is rotationally connected with a cylinder in the vertical channel in a seal fit way; a through hole is formed in a position, dead against the horizontal channel, of the cylinder; the top end of the cylinder is fixedly connected with the output end of a swing hydraulic cylinder; the swing hydraulic cylinder is fixedly connected to the top end of the shell; the shell is provided with a controller and at least one gas sensitive sensor; and the gas sensitive sensors and the swing hydraulic cylinder are connected with the controller. The opening and closing of the valve are automatically controlled by the gas sensitive sensors and the controller. A spring part used by the traditional safety valve is not needed, so that potential safety hazards caused by fatigue failure of a spring are avoided.
Description
Technical field
The present invention relates to a kind of safety valve, one that concrete the is safety valve that surges.
Background technology
Well mouth release valve is the most important valve of wellhead assembly ground safety. Current safety valve is full of high pressure liquid force feed when in use oil cylinder is interior, piston promotes valve in normally open, now the spring in safety valve easily produces fatigue fracture in compressive state for a long time, and after spring breakage, safety valve cannot realize and cutting out, and has very large potential safety hazard.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides the safety valve that surges simple in structure and that security is good.
The present invention deal with problems adopt technical scheme be:
The one safety valve that surges, comprise that inside has the cross housing of vertical passageway and interconnection formation, the diameter of described vertical passageway is greater than the diameter of interconnection, described housing is sealed and matched rotationally and is connected with cylindrical shell in vertical passage, the just right position of described cylindrical shell and interconnection is provided with through hole, the top of described cylindrical shell is fixedly connected with the output of an oscillating motor, described swing hydraulic stem is fixedly connected on the top of housing, on described housing, be provided with at least one gas sensor of controller, described gas sensor is connected with controller respectively with oscillating motor.
As the further improvement of such scheme, described cylindrical shell is provided with sealing ring at the periphery of the both sides up and down of through hole.
As the further improvement of such scheme, described gas sensor is air-sensitive ceramic ring and the outer wall that is arranged on interconnection.
Beneficial effect of the present invention: the rotating cylindrical shell of employing of the present invention, and utilize oscillating motor to control the back rotation of coming of cylindrical shell, realize the switching of interconnection, gather the concentration of the inflammable gases such as airborne carbon monoxide by gas sensor, judge whether that by controller pipeline exists leakage again, and then automatically control that oscillating motor is opened or valve-off, do not need to use the spring members that conventional security valve uses, thereby avoid the spring fatigue potential safety hazard of bringing that lost efficacy.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is internal structure schematic diagram of the present invention.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design, concrete structure and the generation to innovation and creation carries out clear, complete description, to understand fully object, feature and the effect of the invention. Each technical characterictic in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
With reference to Fig. 1, the one safety valve that surges, comprise that inside has the cross housing 1 of vertical passageway and interconnection formation, the diameter of described vertical passageway is greater than the diameter of interconnection, described housing 1 is sealed and matched rotationally and is connected with cylindrical shell 2 in vertical passage, the just right position of described cylindrical shell 2 and interconnection is provided with through hole 21, the top of described cylindrical shell 2 is fixedly connected with the output of an oscillating motor 3, described swing hydraulic stem 3 is fixedly connected on the top of housing 1, on described housing 1, be provided with controller 4 at least one gas sensor 5, described gas sensor 5 is connected with controller 4 respectively with oscillating motor 3.
To the further improvement of embodiment, described cylindrical shell 2 is provided with sealing ring at the periphery of the both sides up and down of through hole 21, further ensures the effect of sealing. In addition, described gas sensor 5 is air-sensitive ceramic ring and the outer wall that is arranged on interconnection.
The present invention gathers the concentration of the inflammable gases such as CO in Air by gas sensor 5, controller 5 judges that automatically controlling oscillating motor 3 according to concentration height rotates, and realizes the switching of valve. The spring members that does not need conventional security valve to use, avoids the spring fatigue potential safety hazard of bringing that lost efficacy.
The above is preferably embodiment of the present invention, and it does not form limiting the scope of the invention, all should belong to protection scope of the present invention as long as realize object of the present invention with essentially identical means.
