Abstract
The utility model discloses a relief valve specifically is a relief valve surges, including the inside cross casing that has vertical passage and interconnection constitution, vertical passage's diameter is greater than the diameter of interconnection, rotationally sealed the cooperation is connected with the barrel to the casing in vertical passageway, the barrel is provided with the through -hole with the just right position of interconnection, the top of barrel and the output fixed connection of a rotary actuator, swing hydraulic stem fixed connection is on the top of casing, be provided with at least one gas sensor of controller on the casing, gas sensor and rotary actuator are connected with the controller respectively. The utility model discloses a switching of automatic control valve door is realized to gas sensor and controller. The potential safety hazard that spring fatigue became invalid and to bring is avoided to the spring part that does not need traditional relief valve to use.
Description
Technical field
This utility model relates to a kind of relief valve, and particularly one is surged relief valve.
Background technology
Well mouth release valve is the most important valve of wellhead assembly flooring-safe.It is full of high pressure liquid force feed time in current relief valve in use oil cylinder, piston promotes valve to be in normally open, now the spring in relief valve is in compressive state for a long time and easily produces fatigue fracture, and after spring breakage, relief valve cannot realize cutting out, and there is the biggest potential safety hazard.
Utility model content
For solving the deficiencies in the prior art, this utility model provides simple in construction and the good relief valve that surges of safety.
This utility model solves problem and the technical scheme is that
One is surged relief valve, including inside, there is vertical passageway and the cross housing of interconnection composition, the diameter of described vertical passageway is more than the diameter of interconnection, described housing seals rotationally in vertical passage and is connected with cylinder, described cylinder and interconnection just to position be provided with through hole, the top of described cylinder is fixing with the outfan of an oscillating motor to be connected, described oscillating motor is fixedly connected on the top of housing, controller and at least one gas sensor it is provided with on described housing, described gas sensor and oscillating motor are connected with controller respectively.
As the further improvement of such scheme, the described cylinder periphery in the both sides up and down of through hole is provided with sealing ring.
As the further improvement of such scheme, described gas sensor is airsensitive porcelain ring and the outer wall being arranged on interconnection.
The beneficial effects of the utility model: the rotating cylinder of employing of the present utility model, and utilize oscillating motor to carry out back rotation to control cylinder, realize the opening and closing of interconnection, the concentration of the inflammable gases such as carbon monoxide in air is gathered by gas sensor, judged whether that pipeline exists leakage by controller again, and then automatically control oscillating motor to be turned on and off valve, need not use the spring members that conventional security valve uses, thus avoid the potential safety hazard that spring fatigue failures brings.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is internal structure schematic diagram of the present utility model.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design, concrete structure and the generation of innovation and creation is carried out clear, complete description, to be completely understood by the purpose of the invention, feature and effect.Each technical characteristic in the invention, can be with combination of interactions on the premise of the most conflicting conflict.
With reference to Fig. 1, one is surged relief valve, including inside, there is vertical passageway and the cross housing 1 of interconnection composition, the diameter of described vertical passageway is more than the diameter of interconnection, described housing 1 seals rotationally in vertical passage and is connected with cylinder 2, described cylinder 2 and interconnection just to position be provided with through hole 21, the top of described cylinder 2 is fixing with the outfan of an oscillating motor 3 to be connected, described oscillating motor 3 is fixedly connected on the top of housing 1, controller 4 and at least one gas sensor 5 it is provided with on described housing 1, described gas sensor 5 and oscillating motor 3 are connected with controller 4 respectively.
Further improvement to embodiment, the described cylinder 2 periphery in the both sides up and down of through hole 21 is provided with sealing ring, is further ensured that the effect of sealing.It addition, described gas sensor 5 is airsensitive porcelain ring and the outer wall being arranged on interconnection.
This utility model gathers the concentration of the inflammable gases such as CO in Air by gas sensor 5, and controller 4 judges that automatically controlling oscillating motor 3 according to concentration level rotates, it is achieved the opening and closing of valve.Need not the spring members that conventional security valve is used, it is to avoid the potential safety hazard that spring fatigue failures brings.
The above is this utility model preferably embodiment, and it is not intended that the restriction to this utility model protection domain, as long as realize the purpose of this utility model with essentially identical means all should belong to protection domain of the present utility model.
