Abstract
The utility model discloses a fusing safety valve of oil pipelines and gas pipelines, and belongs to the technical field of oil and gas equipment. The fusing safety valve of the oil pipelines and the gas pipelines are characterized in that a disc-shaped valve core body control base is fixed on the middle portion inside a valve cavity, a through hole is formed in the central line of the valve core body control base, a valve core body pull rod penetrates through the through hole of the valve core body control base and is fixed with the a valve core body, a valve core body pull rod spring is sleeved on the other end of the valve core body pull rod, one end of a fuse wire is fixed with the valve core body, and the other end of the fuse wire is fixed with an outer hanging point of a high temperature resistance valve shell body. The fusing safety valve of the oil pipelines and the gas pipelines has the advantages that when a fire occurs to the fusing safety valve on a pipeline, the valve can be closed at the first time, and the media inside the pipeline is guaranteed not to leak to cause secondary disasters and property loss in a fire. The fusing safety valve solves the problem that the valves cannot be closed on site by man power or motor power or pneumatic power when fires occur to the valves of the pipelines of the petrochemical industry facilities and equipment.
Description
Technical field
The invention belongs to oil and gas-fired equipment technical field, relate to the improvement of delivering pipe safety valve.
Background technique
At present, along with China's expanding economy, various petrochemical industry facilities and equipments are more and more, and on the pipeline of these facilities and equipment the valve safety control exist under some special fire condition can't the throttle down shortcoming, caused very great fire accident and leakage accident.As Dalian PetroChina Company Limited. port depot pipeline emptying in 2010 catches fire and can not be caused the significance that the oil depot explosive accident all illustrates that pipeline valve is controlled automatically by very first time throttle down.When the common pipe valve runs into fire, need the people to arrive valve place throttle down or electronic or closed pneumatic valve, some fire cause the people to not valve place throttle down or power supply or source of the gas burnt and can't throttle down, thereby valve can not close the very first time, so cause larger disaster and property loss.
Summary of the invention
The objective of the invention is: a kind of oil and gas pipeline fusing safety valve are provided, its throttle down that can just can automatically fuse when running into during Initial Stage of Fire 100 ℃ of left and right Celsius, ensure very first time automatic-closing valve when on pipeline, this fusing Safety valve runs into fire.
Technological scheme of the present invention is: in valve pocket, middle part is fixed with the disc valve core and controls pedestal, have perforation on the center line of valve core control pedestal, the valve core pull bar is controlled the perforation of pedestal and fixes with valve core through valve core, the another end cover of valve core pull bar has the valve core pull-rod spring, fusible link one end and valve core are fixed, and the other end and hot-resistant valve housing store mounting point are fixed.
The invention has the beneficial effects as follows: when on pipeline, the fusing safety valve runs into fire, valve itself can be closed within the very first time, ensures that pipeline internal medium can not occur to leak and initiation secondary disaster and property loss under fire condition.This fusing safety valve has solved on the pipeline of petrochemical industry facilities and equipment when valve runs into fire, by the electronic or pneumatic shortcoming problem that can't realize on-the-spot throttle down of manpower.
The accompanying drawing explanation
Fig. 1 is structural drawing of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in the figure, the 1st, valve pocket, the 2nd, valve core pull-rod spring, the 3rd, valve core is controlled pedestal, the 4th, hot-resistant valve housing, the 5th, valve core, the 6th, fusible link, the 7th, hot-resistant valve housing store mounting point, the 8th, fusing valve body of safety valve flange, the 9th, bolt, the 10th, fusing safety valve and pipeline coupling flange, the 11st, valve core pull bar.
Valve pocket 1 is pipeline medium mobile cavity in safety valve.The effect of valve core pull-rod spring 2 is to retract the valve core throttle down when valve core 5 after fusible link 6 fusing, valve core is controlled pedestal 3 and is played on the one hand the effect of standing valve core body pull-rod spring 2 and valve core pull bar 11, with valve core 5, coordinate on the other hand, realize the interior unlatching of valve pocket 1 and sealing process, get back to valve core control pedestal 3 late gates when valve core 5 and just close, the interior medium of safety valve valve pocket 1 is closed.Valve core 5 is fixing in open mode by fusible link 6 tractions.When valve core 5 during in open mode the interior medium of valve pocket 1 can unobstructedly flow; After fusible link 6 fusing, valve core 5 is returned to valve core and controls throttle down on pedestal 3 under valve core pull-rod spring 2 active forces.When valve core 5, during in closed condition, the interior medium of valve pocket 1 is truncated and stops flowing.Special fusible link 6 is made by low-temperature alloy, this fusible link 6 fusible during in ambient temperature 100 left and right degree centigrade.Under normal circumstances, this fusible link 6 plays 5 effects of traction standing valve core body; In fire uniform temperature situation, this fusible link fusing, valve core 5 is got back to valve core and is controlled throttle down on pedestal 2 under the 2 power effects of valve core pull-rod spring.Hot-resistant valve housing store mounting point 7 plays fixedly fusible link 6 effects under normal circumstances, ensures that valve core 5 is in normally open; When fire temperature reaches 100 left and right degree centigrade, striking point melts away, and fusible link 6 is de-disconnectedly causes valve core 5 returns and in closed condition.
The fusing safety valve: when on pipeline, fusing safety valve valve runs into fire, valve itself can be closed within the very first time, ensures that pipeline internal medium can not occur to leak and initiation secondary disaster and property loss under fire condition.This fusing safety valve has solved on the pipeline of petrochemical industry facilities and equipment when valve runs into fire, by the electronic or pneumatic shortcoming problem that can't realize on-the-spot throttle down of manpower.This fusing safety valve is to have manufactured in factory, can produce flange-type or screw thread type according to user's request, and the user buy and use.On the pipelines such as the most applicable petrochemical industry storehouse, petrochemical equipment, install and use.
