Description
Technical field
The utility model is related to safety valve technical field, specifically related to a kind of air pressure relief valve.
Background technology
Safety valve, that is, be installed in fluid system, to outside when the pressure inside equipment or pipeline is more than warning value
Exhaust fluid reduces a kind of automatic valve of equipment or internal pipe pressure.Safety valve be widely used in each type III pressure vessel,
On gas pipeline or fluid pipeline, to ensure the safe operation of equipment.
The safety valve for being applied to gas apparatus or pipeline at present is typically only capable to realize open valve when internally pressure is excessive
Outside discharge gas, have lacked prompting warning function.When internal pressure kept is excessive, safety valve can continue outwards to discharge gas
Body, and staff possibly cannot be timely detected, continuing excessive pressure may cause the damage of equipment, harm production peace
Entirely.
Utility model content
In order to solve the above problems, the utility model provide one kind can when pressure is excessive outside discharge gas, and
The air pressure relief valve of alarm can be sent.
The utility model is realized using following scheme：
A kind of air pressure relief valve, including valve body, the connector for being connected with equipment, exhaust outlet, located at valve inner
Piston and the flexible member for providing pressure to piston, also including the sliding block located at flexible member and piston space and with row
The alarm of gas port connection；The valve inner is divided into epicoele and cavity of resorption；The epicoele and cavity of resorption are by outside valve body
Connecting tube realizes connection；The flexible member and sliding block are located at epicoele, and the piston is located at cavity of resorption；The sliding block size and valve
Chamber size matches on body, and multiple communicating pipes are provided with inside the sliding block, and the bore of communicating pipe increases successively from top to bottom；The company
Interface is located at cavity of resorption, and exhaust outlet is located at epicoele, and the exhaust outlet is on same axis with the mouth of pipe of the connecting tube, and via cunning
Communicating pipe connection inside block.
Further, the first communicating pipe, the second communicating pipe, that set gradually from top to bottom are included the multiple communicating pipe
Tee joint pipe and the 4th communicating pipe.
Further, described alarm is loudspeaker.
Further, the flexible member is spring.
Compared to prior art, the utility model has the advantages that：
1. the utility model outside discharge gas can reduce internal automatically when pneumatic compression devices internal pressure is excessive
Pressure, the alarm set by exhaust ports can also send alarm while discharge gas.
2. multiple bores set by sliding block of the present utility model inside different communicating pipe, connected when pressure is bigger
Communicating pipe, bore was bigger, so that alarm is differed in the alarm song for being sent at various pressures, facilitated staff
The running status of confirmation equipment.
Brief description of the drawings
Fig. 1 is the structural representation of the present embodiment.
Specific embodiment
For ease of skilled artisan understands that the utility model, below in conjunction with specific embodiments and the drawings to this practicality
It is new to be described in further detail.
Reference picture 1, the utility model embodiment include valve body 1, for be connected with equipment connector 2, for discharging gas
The exhaust outlet 3 of body, the piston 4 located at valve inner and the flexible member 5 for providing pressure to piston.In the present embodiment
Flexible member 5 is spring.A sliding block 6 is additionally provided between flexible member 5 and piston 4.An alarm 7 is also associated with exhaust outlet 3,
Alarm 7 is loudspeaker in the present embodiment.
The inside of valve body 1 is divided into epicoele 11 and cavity of resorption 12, and epicoele 11 is realized connecting with cavity of resorption 12 via a connecting tube 8.Its
Elastic element 5, sliding block 6 are located at epicoele 11 with exhaust outlet 3, and piston is located at cavity of resorption 12.The size of sliding block 6 and epicoele 11
Size matches, and the sliding block 6 is internally provided with multiple communicating pipes 9, and bore increases successively from top to bottom, including the first communicating pipe
91st, the second communicating pipe 92, the communicating pipe 94 of third connecting pipe 93 and the 4th.
Air inlet 81 and exhaust outlet 3 of the connecting tube 8 at epicoele 11 are on same axis, when the communicating pipe 9 in sliding block 6
When between air inlet 81 and exhaust outlet 3, internal gas can be discharged via communicating pipe 9 from exhaust outlet 3.The gas of discharge leads to
Crossing the loudspeaker being connected with exhaust outlet can send sound, so that staff learns that safety valve is in working condition.
The air pressure relief valve that the present embodiment is provided is connected in equipment via connector 2（Do not represented in figure）, when in equipment
When portion's air pressure is normal, flexible member 5 is original state, the access failure air inlet 81 and exhaust outlet 3 of communicating pipe 9 of sliding block 6.Work as equipment
When internal pressure is excessive, internal gas promote piston 4 to move upwards, are moved on sliding block 6, and flexible member 5 is compressed.When sliding block 6
On when moving on to connection air inlet 81 and the exhaust outlet 3 of the first communicating pipe 91, device interior gas is discharged, and sends out siren 7
Go out sound.If the gas flow of the now discharge of the first communicating pipe 91 still cannot reduce internal pressure, sliding block 6 may proceed to shifting,
Second communicating pipe 92 of larger caliber is set to connect air inlet 81 and exhaust outlet 3.Similarly, the sliding block 6 when internal pressure cannot be reduced
Shifting is may proceed to, more bigbore third connecting pipe 93 is connected air inlet 81 and exhaust outlet 3 with the 4th communicating pipe 94.And with
Communicating pipe bore increase, the sound of alarm 7 namely loudspeaker also can be with change.So that staff can be according to sound
The working condition of confirmation equipment, so as to be adjusted to equipment.And when internal pressure is returned to below critical value, compressed
Flexible member 5 promotes piston 4 to return to initial position with sliding block 6, stops to outside discharge gas.
Although being carried out with reference to embodiments above to description of the present utility model, it is familiar with the art
Personnel many replacements, modifications and variations can be carried out according to above-mentioned content, be obvious.Therefore, it is all such
Substitute, improvement and change are included in scope of the appended claims.
