Abstract
The utility model provides a nitrogen valve is annotated in transformer oil extraction and nitrogen injection explosion -proof and fire extinguishing device's automation, which comprises the following components: a valve body, the last lower extreme of valve body has last cavity and lower cavity respectively, goes up the cavity and down through the annular channel intercommunication between the cavity, is provided with the valve rod among the annular channel, and the bottom of valve rod has shutoff portion, and shutoff inferior officer annular channel's lower extreme opening is closed, the part outside that the valve rod stretched into in the cavity is fixed with the piston, is provided with the spring between the bottom of piston and the bottom of last cavity, set up the screw of ventilating on the lateral wall of valve body, the screw of ventilating communicates with each other with annular channel, and you twist and go into to give vent to anger the nut in the screw of ventilating, and the nut that admits air is twisted to the bottom of lower cavity, and the nut that admits air will descend the opening of cavity to seal. The device keeps closed when the transformer runs well, isolated with transformer oil with nitrogen gas, when the transformer catches fire, pours into nitrogen gas into transformer automatically.
Description
Technical field
This utility model relates to a kind of valve, particularly relates to a kind of note for transformator oil draining nitrogen filling explosion-proof fire-extinguishing device
Nitrogen valve.
Background technology
Transformator is in running, it is possible to because the faults such as short circuit, high oil temperature cause phenomenon of catching fire, set for ensureing
Standby safety, applicant have developed and installs a kind of oil draining nitrogen filling fire extinguishing device on the transformer.This device can occur at transformator
During short trouble, discharge the oil in transformator, be then injected into nitrogen, need during nitrogen injection to be injected by special valve.
Utility model content
In order to solve problem present in background technology, this utility model provides that a kind of transformator oil draining nitrogen filling is explosion-proof goes out
The automatic nitrogen injecting valua of fire device, nitrogen, when transformator catches fire, is automatically injected in transformator by this valve.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
The automatic nitrogen injecting valua of a kind of transformator oil draining nitrogen filling explosion-proof fire-extinguishing device, including valve body, it is characterised in that described valve
The upper and lower side of body is respectively provided with cavity and lower cavity, is connected by circular passage, circular passage between upper cavity and lower cavity
In be provided with valve rod, the bottom of valve rod has closure part, and the lower ending opening of circular passage is closed by closure part；
Valve rod stretches into the portion outboard in cavity and is fixed with piston, arranges between bottom and the bottom of upper cavity of piston
Having spring, the upper end of valve body is provided with end cap, and piston and spring are enclosed in upper cavity by end cap；
Arranging ventilation screw on the sidewall of valve body, ventilation screw communicates with circular passage, is screwed with and gives vent to anger in ventilation screw
Nut, the bottom of lower cavity is screwed with air inlet nut, and air inlet nut is by the closure of openings of lower cavity.
Air inlet nut and nut of giving vent to anger are both provided with air flue.
Closure part is from the outwardly frustum of stem bottom.
The sealing ring of annular it is provided with on the side of described frustum.
The beneficial effects of the utility model are: this device keeps when transformator runs well closing, by nitrogen and transformation
Device oil phase is isolated, and when transformator catches fire, is automatically injected in transformator by nitrogen.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further illustrated
Fig. 1 is the schematic appearance of automatic nitrogen injecting valua described in the utility model；
Fig. 2 is the cross-sectional view of automatic nitrogen injecting valua described in the utility model.
Detailed description of the invention
This utility model is further described by explanation and detailed description of the invention below in conjunction with the accompanying drawings:
Embodiment 1
As shown in Figure 1-2, the automatic nitrogen injecting valua of a kind of transformator oil draining nitrogen filling explosion-proof fire-extinguishing device, including valve body 1, valve body
The upper and lower side of 1 is respectively provided with cavity 7 and lower cavity 3, is connected by circular passage between upper cavity 7 and lower cavity 3, and annular is logical
Being provided with valve rod 2 in road, the bottom of valve rod 2 has closure part 4, and closure part 4 is from the outwardly frustum of stem bottom, closure
The lower ending opening of circular passage is closed by portion 4.The sealing ring of annular it is provided with on the side of frustum.
Valve rod 2 stretches into the portion outboard in cavity 7 and is fixed with piston 9, the bottom of piston 9 and the bottom of upper cavity 7 it
Between be provided with spring 10, the upper end of valve body 1 is provided with end cap 8, and piston 9 and spring 10 are enclosed in upper cavity 7 by end cap 8.
Arranging ventilation screw on the sidewall of valve body 1, ventilation screw communicates with circular passage, is screwed with and gives vent to anger in ventilation screw
Nut 5, the bottom of lower cavity 3 is screwed with air inlet nut 6, and air inlet nut 6 is by the closure of openings of lower cavity 3.Air inlet nut and giving vent to anger
Nut is both provided with air flue.
Under normal circumstances, nitrogen enters in lower cavity 3 by the air flue of air inlet nut 6, upwarding pressure at nitrogen
Under effect, the closure part 4 of push rod 2 holds out against the bottom in circular passage, thus stops running out of of nitrogen.When needs irrigate nitrogen
Time, automaton drives valve rod 2 to move downward, and at this time the opening of bottom, circular passage 2 is opened by closure part, at this time nitrogen
Just inject from the air flue of nut of giving vent to anger.
It will be recognized by those skilled in the art, on the premise of without departing from protection scope of the present invention, can be to above-mentioned
Embodiment carries out various amendment, changes and combine, and think this amendment, to change and combine be the model in originality thought
Within enclosing.
