Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-3, a kind of fire-fighting lance with slow pressure decompression effect, including hydraulic giant main body 1 and pressure-equalizing pipe
8, one end of hydraulic giant main body 1 is equipped with nozzle 2, and 1 middle part of hydraulic giant main body is fixed with handle 3, the other side at 1 middle part of hydraulic giant main body
It is fixed with turntable 12, the middle part of turntable 12 is sequentially connected by valve rod and the spool 13 being placed in the middle part of 1 inner wall of hydraulic giant main body, water
The other end of gun main body 1 is equipped with connectivity port 5, and the inside of connectivity port 5, which is connected together, pressure-equalizing pipe fixing piece 4, pressure
The outside of balance pipe fixing piece 4 and connectivity port 5 is tightly connected by sealed connecting component 6, the inside of pressure-equalizing pipe fixing piece 4
Equipped with pressure-equalizing pipe 8, the bottom of 8 side of pressure-equalizing pipe offers tap hole 9, one end of pressure-equalizing pipe fixing piece 4 with
The bottom end of municipal water pipe connection, 1 side of hydraulic giant main body is equipped with partial pressure pipe 7, and partial pressure pipe 7 passes through runner 11 and pressure-equalizing pipe 8
Bottom end be in contact, the bottom opening of runner 11 is in tap hole 9 on same straight line, and interlaced setting.
Wherein, the both ends of pressure-equalizing pipe 8 are equipped with push plate, and the push plate of side passes through compressed spring 10 and hydraulic giant main body 1
Inner wall be fixedly connected, voltage stabilizing is played the role of by compressed spring 10.
Wherein, the surface of handle 3 is equipped with wavy protrusion, and the outer cover of handle 3 is equipped with the soft set of sponge, facilitates fire-fighting
It is uncomfortable to reduce the hand that long period of operation is brought for the crawl and gripping of personnel.
Wherein, the runner at 8 middle part of pressure-equalizing pipe is communicated with the sprue inside hydraulic giant main body 1, and is in same straight line
On, so that flow is normally circulated from the middle part of pressure-equalizing pipe 8 and the middle part of hydraulic giant main body 1.
Wherein, partial pressure pipe 7 is made of PVC hose, and PVC hose soft texture facilitates dragging, reduces fire-fighting and offsets in the process
The operation of anti-personnel impacts.
It should be noted that the utility model is a kind of fire-fighting lance with slow pressure decompression effect, when specific works, by
One end of hydraulic giant main body 1 is connect with municipal water pipe, lifts hydraulic giant by handle 3, rotation turntable 12 makes to be placed in inside hydraulic giant main body 1
Spool 13 generate rotation, so that flow is sprayed from nozzle 2, when the pressure inside hydraulic giant main body 1 is excessive, hydraulic pressure to pressure put down
One end of weighing apparatus pipe 8 generates certain thrust, when the thrust is more than thrust of the compressed spring 10 to 8 other end of pressure-equalizing pipe,
Compressed spring 10 will produce contraction, is placed in the tap hole 9 of 8 bottom of pressure-equalizing pipe at this time and can slowly be overlapped with runner 11, from
And imported into part flow in partial pressure pipe 7 by runner 11, reduce the hydraulic pressure in hydraulic giant main body 1 in time, avoids due to water
It presses through greatly, hydraulic giant main body 1 is difficult to control, and on the other hand, when hydraulic pressure reduction makes, flow is small to the pressure of 8 one end of hydraulic balance pipe
When the elastic force of compressed spring 10, compressed spring 10 can promote pressure-equalizing pipe 8 to side, to make tap hole 9 and shunting
It is staggered between road 11, the flow entered inside runner 11 is gradually reduced, until flow is equal to the thrust of pressure-equalizing pipe 8
Compressed spring 10 no longer moves the thrust of pressure-equalizing pipe 8, pressure-equalizing pipe 8, and the hydraulic pressure inside hydraulic giant main body 1 also tends to surely
The phenomenon that determining, hydraulic pressure can't be caused too small, can not provide jetting occurs.
