Specific embodiment
The utility model is described further with reference to embodiment, but is not limited to the content on specification.
As shown in Figure 1, Figure 2 and Figure 3, the utility model is related to a kind of dual signal feedback device, it is opened including leakage alarm
1 is closed, starts alarm switch 2, rest pad 3, valve body 4, piston 5, spring 6, sealing ring 7, protective cover 8, crosses coil 9, conducting wire 10, connects
Line terminals 11, chamber 12 and centre bore 13；Rest pad 3 and valve body 4 are cylindricality, and 3 bottom of rest pad is threadedly coupled with valve body 4,
Cavity is respectively equipped with inside valve body 4 and rest pad 3, two cavitys connect to form chamber 12, and spring 6 and piston 5 are arranged on chamber
In 12, spring 6 is arranged between piston 5 and rest pad 3, and spring 6 can prevent piston 5 without external forces to moving up
Dynamic, 4 bottom of valve body is equipped with through-hole, is connected with chamber 12, when piston 5 moves upwards, external atmosphere pressure can be made to enter chamber
12, so as to which piston 5 be pushed to move, 5 bottom of piston is equipped with sealing ring 7, and sealing ring 7 is arranged tightly on piston 5, and can be with
Piston 5 moves up and down, and sealing ring 7 can ensure air-tightness between piston 5 and chamber 12, allows gas not from piston 5
Gap between chamber 12 is run out of, and then is influenced piston 5 and normally moved up and down, and 3 top of rest pad is equipped with centre bore 13, in
Heart hole 13 is communicated with chamber 12, the setting of 13 both sides of centre bore there are two the different plane of height, leakage alarm switch 1 be mounted on compared with
High plane starts alarm switch 2 and is mounted on compared with low degree, and ladder is set to set two switches that can control two respectively in this way and is opened
The startup and closing of pass, leakage alarm switch 1 are connect with starting alarm switch 2 by conducting wire 10 with wire connection terminal 11 respectively；It is living
Plug 5 is multidiameter structure, and maximum gauge is more than 13 diameter of centre bore of 3 top open part of rest pad, limit is played to piston 5
Position effect, protection spring 6 will not generate fatigue due to compression is excessive, and the smallest end of piston 5 passes through 3 top center of supporting block for location
Hole 13, in leakage alarm switch 1 with starting among alarm switch 2, effect is to ensure that device separates two under normal pressure state
Switch shrapnel, in order to avoid piston 5 destroys switch shrapnel when acting, the cover of protective cover 8 is insulating materials, protects mounted in 3 top of rest pad
Sealing structure is equipped between cover 8 and rest pad 3, can insulate and protects leakage alarm switch 1 and starts alarm switch 2 not by outer
Boundary destroys, and coil 9 is eccentric excessively is mounted on 8 top of protective cover, prevents piston 5 from supporting coil 9, shadow when moving upwards
The normal operation of equipment is rung, excessive wear between conducting wire 10 and protective cover 8 can be prevented by crossing coil 9, in turn result in the damage of equipment
Bad, conducting wire 10 passed through coil 9 to be connect with wire connection terminal 11.
Dual signal feedback device is mounted on self-extinguishing equipment, is usually acted in the internal storage pressure of fire-extinguishing apparatus
Under, 6 preset spring force of spring prevents piston 5 from being moved up under the influence of no external force, since the diameter of the most big end of piston 5 is big
In 3 intracavity diameter of rest pad, piston 5 be moved at its most outside diameter when top is contacted with 3 bottom of rest pad position it is motionless, this
When 5 axle body of piston by leakage alarm switch 1 and start the pressure of alarm switch 2 shrapnel, two microswitches are in normally open, no
Alarm signal externally is sent out, as shown in Figure 3；When fire-extinguishing apparatus generates leakage, pressure slowly declines in equipment, and piston 5 is in bullet
Start to move down under the action of 6 spring force of spring, when pressure leakage is to setting minimum safe working pressure, 5 axle body of piston
It leaves leakage alarm and switchs 1 shrapnel, leakage alarm signal is fed back to controlling alarm by leakage alarm switch 1 in normally off
System notifies the timely repair apparatus of operator on duty, starts alarm switch 2 at this time and maintains normally open, as shown in Figure 2；Work as fire extinguishing
When equipment starts sprinkling, pressure rapid decrease in fire-extinguishing apparatus, piston 5 is rapidly moving downward under the action of 6 spring force of spring,
5 axle body of piston leaves leakage alarm switch 1 and starts the shrapnel of alarm switch 2 in succession, and two microswitches are in normally closed at this time
State, while leakage alarm and startup alarm signal are fed back into alarm control system, notify operator on duty's extinguishing device
Start sprinkling and as early as possible repair recovery, as shown in Figure 1.
Obviously, the above embodiment of the utility model is only intended to clearly illustrate the utility model example,
And it is not the restriction to the embodiment of the utility model.For those of ordinary skill in the art, it is stated upper
