Description
Technical field
The utility model relates to a kind of fire-protection equipment, more specifically to a kind of fire-fighting that is used for fire-protection equipment gas release valve.
Background technique
The gas release valve that existing fire-protection equipment adopted, press the switch of gas release valve usually after, need come Open valve by driving mechanism, pressurized gas is discharged from valve.
Because the driving mechanism of above-mentioned this gas release valve need adopt many component, so the structure more complicated of gas release valve, manufacture cost is higher.And the power by Push switch is come Open valve, needs the user to apply enough power, can open, and relatively requires great effort, and the more weak people (as child, the old,weak,sick and disabled's people) of strength is difficult to use.In addition, too much part causes fire-protection equipment more fault to occur easily in depositing process, if break down during breaking out of fire, then can cause serious consequence.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of fire-fighting gas release valve is provided, and can utilize the pressurized gas in the fire-protection equipment to come Open valve, and the technological scheme of employing is as follows:
Fire-fighting of the present utility model gas release valve, comprise valve base, last valve cover, lower valve lid, last valve cover is fixed on the valve base upper end, the lower valve lid is fixed on the valve base lower end, it is characterized in that: also be provided with braking device and braking device opening mechanism, the left surface of described valve base has air-inlet cavity, right flank has outlet chamber, separate with dividing plate between air-inlet cavity and the outlet chamber, have attachment hole on the dividing plate, described braking device is blocked attachment hole, and the braking device opening mechanism is located on the valve cover, and the braking device opening mechanism is connected with braking device.When needing to discharge gas, the braking device opening mechanism forces braking device to leave attachment hole, makes that the pressurized gas in the fire-protection equipment can enter outlet chamber by attachment hole from air-inlet cavity, discharges, puts out a fire from outlet chamber then.
A kind of more excellent scheme, described braking device opening mechanism comprises push rod and gas driving mechanism, described gas-powered mechanism comprises valve switch, breather line, booster cavity, described going up between valve cover and the valve base forms slidably chamber, described push rod lower end connects braking device, push rod upper end is passed valve base and is stretched into slidably in the chamber, and the push rod upper end is provided with piston, the slidably side in chamber is close in the side of piston, the upper surface of piston has the supercharging groove, and the upper surface of piston props up the slidably end face in chamber, the supercharging groove is communicated with the breather line outlet, the breather line inlet is communicated with air-inlet cavity, and valve switch is located at breather line middle part, piston, the slidably end face in chamber and slidably the side formation booster cavity in chamber.At ordinary times, valve switch is closed; When valve switch is opened, pressurized gas in the fire-protection equipment enter booster cavity from breather line, form a very large pressure, force piston to descend, the piston band push rod and braking device descends, opens attachment hole, pressurized gas in the fire-protection equipment just can enter outlet chamber by attachment hole from air-inlet cavity then, discharge, put out a fire from outlet chamber then.
More excellent scheme, described valve switch is positioned at the valve cover top, and the valve switch upper end is provided with control piece, and the control piece lower end connects valve switch, and valve cover is stretched out in the control piece upper end.
For the ease of opening valve switch, described control piece is a thimble.Press the top of thimble as the user, valve switch is just opened in the thimble bottom, pressurized gas in the fire-protection equipment enter booster cavity by breather line, piston upper surface is applied enough big power, force piston to drive push rod, braking device decline, open attachment hole, the pressurized gas in the fire-protection equipment just can enter outlet chamber by attachment hole from air-inlet cavity then, discharge, put out a fire from outlet chamber then.
For the ease of Push switch, play the dust-tight effect simultaneously, described thimble top is provided with valve cap.In breaking out of fire not, valve cap plays the dust-tight effect; Work as breaking out of fire, when needing to use, the user presses valve cap, drives thimble decline, thereby opens valve switch.
In order to allow braking device before fire-fighting is opened with the gas release valve, can not block attachment hole automatically, and discharged and to have got back to original position automatically behind the gas, block attachment hole, the bottom of described braking device also is provided with return spring, described return spring one end connects braking device, and the return spring the other end connects the madial wall of air-inlet cavity.In not breaking out of fire, daily depositing, return spring forces braking device to rise, block attachment hole; Work as breaking out of fire, when needing to use, the power that the braking device opening mechanism forces braking device to overcome return spring descends, and attachment hole is opened; After finishing using, return spring drives braking device and rises, blocks attachment hole.
For when braking device is blocked attachment hole, avoid the problem that leaks air between braking device and the attachment hole, the end face of described braking device is provided with sealing gasket.When braking device was blocked attachment hole, sealing gasket was blocked the slit between braking device and attachment hole, thereby effectively avoided gas leakage.
The utility model beneficial effect against existing technologies is, because the braking device opening mechanism utilizes the pressurized gas in the fire-protection equipment to come Open valve, therefore effectively reduce the required power of Push switch, no matter adult, child still are that the less people of other strength can open; And the braking device opening mechanism significantly reduces the number of parts, simplifies the structure, and has reduced cost of production, has effectively reduced the probability that mechanical failure takes place, and has prolonged the working life of fire-fighting usefulness gas release valve.
