Abstract
The utility model relates to a novel spring impact opening bottle head valve which is used for gas fire-extinguishing systems, composed of a housing (1), a puncturing needle (3) for a spring (2), a stop motion mechanism (4) and a membrane slice (5), wherein, the compression spring is positioned between the housing and the puncturing needle and is limited by the stop motion mechanism, and after the spring is expanded, the puncturing needle can be driven to puncture the membrane slice; the stop motion mechanism can be various position limiting mechanism such as a pin bolt, a semi-circular shaft, a cam, a convex block, etc. which can limit positions for the spring from the side, the upper or the lower surfaces of the puncturing needle; moreover, the position limiting states of the spring can be changed by pneumatic operation, electric operation or mechanically manual operation.
Description
The utility model belongs to the fire prevention field, is a kind of bottle valve in the gas extinguishing system.
Bottle valve is the important component of gas extinguishing system, and its effect is with the sealing metal diaphragm extinguishing chemical to be left in the storage bottle when not putting out a fire; During fire extinguishing diaphragm punctured the release extinguishing chemical.Usually adopt subordinate's method that diaphragm is punctured: gases at high pressure promote the piston drive and puncture acupuncture rupture of membranes sheet.This mode that punctures diaphragm has following shortcoming: 1) produce enough pneumatic motive forces on the piston for guaranteeing; piston is provided with rubber seal; thereby the resistance of motion of piston is strengthened; particularly after product used 2-3, the aging of rubber seal usually can make the piston akinesia.2) under the situation of pneumatic inefficacy, for guaranteeing puncturing of diaphragm, need the manually opened device of design emergency machine on bottle valve, this hand gear will guarantee to produce bigger pierce force on the one hand, guarantee the sealing property of bottle valve on the other hand again, be the structure more complicated of the hand gear that satisfies above-mentioned requirements, processing is difficulty relatively.
The purpose of this utility model is exactly to find a kind of scheme that reliably, simply punctures seal membrane.
The purpose of this utility model is achieved in that the impulsive force of utilizing compressed spring to produce punctures diaphragm when discharging.Spring is placed in the housing, one end of spring withstands on the housing, and the other end withstands on movable puncturing on the pin, and spring is in compressive state in advance, carry out spacingly by the stop mechanism that is installed on the housing to puncturing pin, stop mechanism punctures pin when being in spacing state and can't move.In case the state of stop mechanism is changed, removed puncturing the motion restriction of pin, under the effect of spring force, puncture pin will accelerated motion to contacting and puncture diaphragm with the sealing metal diaphragm.
Stop mechanism can be various position-limit mechanisms such as pin, semicircle axle, cam, projection, can from puncture the pin side, above or below spring is carried out spacing, the change of the spacing state of stop mechanism can be by pneumatic, electronic or mechanically manually realize.Puncture pin and can be designed to an integral body, also can be designed to piston and the sub-assembly that punctures two parts of pin, drive during the piston motion and puncture needle movement.
Compare with traditional bottle valve, this new bottle head valve has following advantage: 1) puncture the rubber seal that need not be provided for sealing between pin and the housing, thereby do not exist the big or tired sealing ring of the resistance of motion aging and cause puncturing the malfunctioning phenomenon of needle movement.2) puncturing of diaphragm is to discharge the energy that is produced by spring to realize, the release of spring is finished by the action of stop mechanism again, and the action of stop mechanism only need overcome less resistance, no matter be pneumatic strength, electronic strength or manually strength all can change the state of stop mechanism, finish the purpose that retracting spring punctures diaphragm, therefore pneumatic to this bottle valve electronicly or manually opened all realized easily.
Accompanying drawing is the detailed structure view of this utility model, and by housing (1), spring (2) punctures pin (3), stop mechanism (4), and metal seal membrane (5) is formed.Extinguishing chemical import (6) and extinguishing chemical outlet (7) is arranged on the housing (1).Its operation principle is as follows: spring (2) is in compressive state usually, and spring force makes piston (3) that the trend of downward motion be arranged, and the state of stop device (4) can not move spring (2); During fire extinguishing, change the state of stop mechanism (4) by manual, electronic or pneumatic mode, removed the motion restriction to piston (3), spring (2) extension drive punctures the downward rapid movement of pin (4) and punctures diaphragm (5), makes extinguishing chemical flow to outlet (7) by import (6).
Claims (5)
1, a kind of gas extinguishing system bottle valve, by housing (1), spring (2), puncture pin (3), stop mechanism (4), diaphragm (5) is formed, be primarily characterized in that compression spring (2) is in housing (1) and punctures between the pin (3) and spacing by stop mechanism (4), spring (2) is upheld the back and is pushed up to puncturing pin (3).
2, the described bottle valve of claim 1 is characterized in that stop mechanism (4) can be various position-limit mechanisms such as pin, semicircle axle, cam, projection.
3, the described bottle valve of claim 1, it is characterized in that stop mechanism (4) can from puncture the pin side, above or below carry out spacing to spring.
4, the described bottle valve of claim 1 is characterized in that stop mechanism (4) can be by pneumatic, electronic or mechanical its spacing state that manually changes.
5, the described bottle valve of claim 1, it is characterized in that puncturing pin (3) can be an integral body, also can be piston and the sub-assembly that punctures the pin formation.
