Abstract
The utility model relates to a gas flow rate control safety device, which is composed of a shell body, a pressing cover device, and a valve plug device, wherein, the valve plug device is arranged in the shell cavity body; when the valve plug is jacked upwards, the flowing of the gas is blocked in the cavity body; the upper end of the shell body is equipped with the pressing cover device with a push rod. The gas flow rate control safety device of the utility model changes the position of original air inlet channel passing cross, and adopts a plastic valve plug safety structure. The utility model has the advantages of safety and reliable structure, strong air tightness, reasonable design, compact structure, complete functions, convenient operation, and high durability, and furthermore, the utility model reaches the best safety function. The utility model is an optimal safety device.
Description
The utility model relates to a kind of novel gas flow-control safeties.
The gas flow of public use is controlled safeties on the market at present, be to be provided with a push rod device mostly in upper end, place, gas access, this push rod device is with spring outward, and be provided with a ball in the porch, when the gas flow that enters surpasses normal value, ball can be promoted by gas, the gas outlet is blocked, to stop the regular supply of combustion gas.When pressure recovers just often, must manually push rod down be pushed, the ball that is blocked in the place, gas outlet is resetted, thereby make ventilation keep normal again.Though the safeties of this traditional structure can reach the purpose of fixing a breakdown, but this device must rush open ball by means of push rod, can make ball surface produce coarse and wearing and tearing after repeatedly using, when blocking the gas outlet again, just can't reach airtight effect, make safeties lose the effect of security insurance.
The purpose of this utility model be to provide a kind of safe and reliable, air-tightness is strong, novel gas flow-control safeties rational in infrastructure, long-lived.
The purpose of this utility model is achieved through the following technical solutions: it is to be made of housing, pressing device and valve plug device, it in the housing cavity of a hollow, housing is provided with air inlet and the gas outlet that is connected with cavity, be divided into two rooms up and down in the cavity, upper chamber is connected with the gas outlet, and lower chamber is connected with air inlet, and a valve plug device is housed in lower chamber, the top diameter of valve plug can be blocked two rooms when making valve plug make progress jack-up and communicate greater than the bore that two rooms communicate and locate.The pressing device of band push rod is housed in the upper end of housing.
Gas flow control safeties of the present utility model change the position of crossing of original air intake duct, adopted plastic cement valve plug safety structure, have safe and reliable, air-tightness is extremely strong, reasonable in design, compact conformation, multiple functional, easy to use, long-lived advantage, can effectively reach the function of best insurance, be the optimal safeties of user.
Fig. 1 is a kind of preferred construction schematic diagram of the utility model under aeration status.
Fig. 2 is a kind of preferred construction schematic diagram of the utility model under the state of blocking-up ventilation.
In order to make the utility model structure clear more complete, the utility model is described further below in conjunction with accompanying drawing.
As Fig. 1 or shown in Figure 2, the utility model is made of housing 1, pressing device 2 and valve plug device 3, it in the housing 1 cavity of a hollow, housing 1 is provided with air inlet 4 and the gas outlet 5 that is connected with cavity, is divided into two rooms up and down in the cavity, and upper chamber 6 is connected with gas outlet 5, lower chamber 7 is connected with air inlet 4, a valve plug device 3 is housed in lower chamber 7, and the top diameter of valve plug 31 can be blocked two rooms when making valve plug 31 make progress jack-up and communicate greater than the bore that two rooms communicate and locate.In the upper end of housing 1 pressing device 2 is housed.Valve plug device 3 is made of the valve rod 32, spool 33, valve casing 34, driving lever 35 and the spring 36 that fuse with valve plug 31, the upper end of valve casing 34 is fixedly connected on the below of housing 1 by engage thread, spool 33 is positioned at valve casing 34, the lower end of spool 33 is provided with external screw thread, be connected with the internal thread of valve casing 34 lower ends, driving lever 35 is fixedly connected on the below of spool 33; When stirring driving lever 35,32 of spool 33 and valve rods can produce relative rotation, and make spool 33 to rising or to decline; Have a hole in the upper end of spool 33, spring 36 is housed in the hole, sitting above spring 36 has valve rod 33, and valve plug 31 is seated at the top of valve rod 33.Above housing 1, be provided with pressing device 2, pressing device 2 by gland 21, push rod 22, spring 23, and sealing ring 24 constitute, gland 21 fuses with push rod 22, gland 21 is positioned at the top of push rod 22, be with spring 23 outside the epimere of push rod 22, spring 23 and gland 21 all are positioned at outside the housing 1, and the top of housing 1 has the hole that communicates with upper chamber, the hypomere of push rod 22 is positioned at upper chamber 6, is positioned at the push rod 22 outer sealing rings 24 that are with of upper chamber 6.
As shown in Figure 2, when flow-control defective valve on the Gas appliance or pipeline leakage, the gaseous-pressure super large of inflow, the elastic force of the air pressure of super large and volute spring 36 promotes valve plug 31 and blocks the gas port of upper chamber 6 rapidly, stop combustion gas and leaked outside, reached the effect of insurance.After fault is got rid of, if gas normally circulates, only need gland 21 is down pushed, make push rod that valve plug 31 is pushed away the gas port of upper chamber 6, gas is passed through smoothly, decontrol gland, push rod rises under the effect of elastic force and resets, the normal condition of recovery Fig. 1.This device is by stirring driving lever 35, the size that can regulate actual using gases flow.
For the gas that enters safeties is kept clean, be provided with screen pack 8 at the air inlet place.
