Abstract
The residual pressure alarm device for oxygen respirator is formed from high-pressure connector, valve rod, whistle, shell body, spring, regulating screw rod, screw plug and back cap, the high-pressure connector is connected with high-pressure end of pressure reducer, the valve rod and spring are placed in the middle portion of shell body, the whistle is connected with side end hole of shell body, the regulating screw rod is connected with medium-pressure end of pressure reducer, when the alarm is given, the whistle can be blown by medium-pressure gas to give out alarm sound, and after a certain time, the alarm can be automatically released. The structure has the characteristics of accurate alarm, adjustable alarm duration, simple structure, convenient use and high safety performance.
Description
This utility model is to be used for reminding the oxygen breathing apparatus wearer, and when the gas cylinder internal pressure has only 4-6MPa, the up time is reminded the device of wearer's safe escape working site when being 50-60 minute.
The oxygen breathing apparatus of existing domestic production is not established the overbottom pressure alarm device, is reminded the work of wearer's overbottom pressure can only observe oxygen gauge by the moment service time, and it is very inconvenient that the wearer is used, and forget easily.And the external oxygen breathing apparatus of producing adopts is mechanical overbottom pressure alarm device, and its persistent period of reporting to the police is adjustable scarcely.If time of fire alarming is too short, when working, the wearer can't hear easily; If time of fire alarming is long, oxygen consumption again can be very big, will influence the oxygen breathing apparatus nominal operation time.
It is accurate that the purpose of this utility model provides a kind of warning, the high a kind of oxygen breathing apparatus overbottom pressure alarm device of adjustable, simple in structure, the easy to use, safe performance of persistent period of reporting to the police.
The purpose of this utility model is achieved in that high pressure connection (1) is connected with the decompressor high-pressure side, and valve rod (10) and spring (9) are provided in a side of the middle part of housing (8), and whistle is connected with the case side stomidium, adjusts screw rod (12) and is connected with the decompressor intermediate voltage terminal.
The utlity model has performance height simple in structure, easy to use, safe, accurate, the adjustable advantage of persistent period of reporting to the police of warning.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is an oxygen breathing apparatus overbottom pressure alarm device structure chart.
1, high pressure connection 2, sealing ring 3, sealing ring 4, whistle mouth 5, whistle joint 6, screw 7, nylon cushion 8, housing 9, spring 10, valve rod 11, sealing gasket 12, adjustment screw rod 13, adjusting pad 14, sealing ring 15, plug 16, sealing ring 17, back of the body medicated cap.
High pressure connection 1 is connected with the decompressor high-pressure side, valve rod 10 and spring 9 are contained in the middle part of housing 8, valve rod 10 actions are promoted by gases at high pressure and spring 9, the warning opening pressure is by spring 9 controls, the persistent period length of reporting to the police is by the stroke decision of valve rod 10, adjusting screw rod 12 links with the decompressor intermediate voltage terminal, and the energy move left and right is adjusted the stroke of valve rod 10, the realization time of fire alarming is adjustable, whistle is made up of whistle joint 5, whistle mouth 4, screw 6, be connected with the shell-side end, the whistle that blows the housing side by medium pressure gas during warning sends chimes of doom.
Open the oxygen cylinder switch during work, gases at high pressure promote valve rod 10 and move right, and have in a flash and report to the police, and sealing gasket 11 contacts with adjusting screw rod 12, and middle pressure gas channel is closed.When intrinsic pressure 4-6MPa is arrived in oxygen cylinder work, the pressure of spring 9 and oxygen cylinder pressure are in poised state, valve rod 10 is at the uniform velocity to left movement, middle pressure gas channel is opened, medium pressure gas blows whistle mouth 4 and sends warning, in the sealing ring on the valve rod 10 entered φ 6 holes of housing 8, middle pressure gas channel was plugged again, and warning automatically terminates.
Claims (1)
1, a kind of oxygen breathing apparatus overbottom pressure alarm device, form by high pressure connection, valve rod, whistle, housing, spring, adjustment screw rod, plug, back of the body medicated cap, it is characterized in that being provided with and adjust screw rod (12), adjust screw rod and link to each other with the decompressor intermediate voltage terminal, the energy move left and right is adjusted the stroke of valve rod (10).
