Description
Technical field
It the utility model is related to fire-fighting equipment technical field, more particularly to a kind of fire pump of carry potential overflow pipeline.
Background technology
Fire pump has the situation that all ball valves are all closed often in the course of the work, and now fire-fighting pump pressure can steeply rise
And exceed the maximum pressure upper limit, and pressure is excessive not only can be to pump body structure intensity, bolt strength and the seal of fire pump
Performance have an impact, it is excessive to will also result in engine loading, causes to stall, and then gearbox and running part are made
Into impacting and influence its service life.
Utility model content
The purpose of this utility model is to provide a kind of fire pump of carry potential overflow pipeline, for solving in background technology because disappearing
Anti- all ball valves of pump, which are closed, causes outlet pressure to reach maximum and bear caused problem during upper pressure limit.
To achieve the above object, the technical scheme that the utility model is taken is：A kind of fire pump of carry potential overflow pipeline, including
Fire pump, the first overflow pipe, the second overflow pipe and overflow pipe adapter, the water outlet of the fire pump is provided with first and overflow
Head piece, the water inlet of the fire pump is provided with the second overfall, the 3rd is provided with the overflow pipe adapter and is overflow
Head piece and the 4th overfall, it is provided with the overflow pipe adapter and connects overflowing for the 3rd overfall and the 4th overfall
Flow tube chamber, first overfall are connected with the 3rd overfall by the first overflow pipe, second overfall and the 4th overflow
Mouth passes through the second overflow pipe and connected.
In such scheme, the overflow pipe intracavitary is provided with plug and spring, and the plug is located at one end of overflow tube chamber
And contacted with the first overflow pipe, the spring is located at the other end of overflow tube chamber and neck contacts with plug, afterbody and overflow pipe
Adapter inwall contacts.
Operation principle of the present utility model is：When the water outlet pressure of fire pump rises, current are from fire pump
First overfall is entered in the first overflow pipe, then is entered by the first overflow pipe in overflow pipe adapter and promoted plug compression bullet
Spring, plug is crossed the 4th overfall on overflow pipe adapter, then exited into from the 4th overfall to the second overflow pipe
In, finally exit into the second overfall of fire pump from the second overflow pipe, finally flow back into fire pump, so as to realize
To the purpose of fire pump pressure release.
Compared with prior art, the utility model has the advantages that：
(1) High-Pressure Water at fire pump discharge mouth returns to fire pump water inlet by overflow passage, effective to realize
Circulated in current, ensure that current are not excessive, reduce water resource waste；
(2, which avoid fire pump water flow pressure, rises destruction to fire-fighting pump configuration part and because load rise is to engine
Operating, the damage of speed change punch-out equipment power transmission shaft, reduce engine energy consumption, extend the service life of fire pump and fire fighting truck.

Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to the drawings and specific embodiments, it is expanded on further how the utility model is implemented.
As shown in figure 1, a kind of fire pump of carry potential overflow pipeline provided by the utility model, including fire pump 1, the first overflow
Pipe 2, the second overflow pipe 3 and overflow pipe adapter 4, the water outlet of fire pump 1 is provided with the first overfall 5, in fire pump 1
Water inlet be provided with the second overfall 6, the 3rd overfall 7 and the 4th overfall 8 are provided with overflow pipe adapter 4,
Be provided with the overflow tube chamber 9 of connection the 3rd overfall 7 and the 4th overfall 8 in overflow pipe adapter 4, the first overfall 5 and
3rd overfall 7 is connected by the first overflow pipe 2, realize between overflow pipe adapter 4 and the delivery port of fire pump 1 current by,
Second overfall 6 is connected with the 4th overfall 8 by the second overflow pipe 3, realizes overflow pipe adapter 4 and the water inlet of fire pump 1
Between current pass through.
Be provided with plug 10 and spring 11 in overflow tube chamber 9, plug 6 be located at one end of overflow tube chamber 9 and with the first overflow
Pipe 2 contacts, and spring 10 is located at the other end of overflow tube chamber 9 and neck contacts with plug 9, afterbody and the inwall of overflow pipe adapter 4
Contact.
Operation principle of the present utility model is：
As shown in Fig. 2 (one) when the water outlet pressure of fire pump 1 rises, current are from the at fire pump discharge mouth
One overfall 5 is entered in the first overflow pipe 2, then is entered by the first overflow pipe 2 in overflow pipe adapter 4 and promoted plug 10
Downward compression spring 11, plug 10 is crossed the 4th overfall 8 on overflow pipe adapter 4, and from the 4th overfall 8 flow out into
Enter into the second overflow pipe 3, then exited into from the second overflow pipe 3 into the second overfall 6 of fire pump water inlet, finally
It flow back into fire pump 1, so as to be embodied as fire pump pressure release；
(2) after fire pump pressure release terminates, the pressure of the water outlet of fire pump 1 declines, the hydraulic pressure drop in overflow passage
Low, bounce-back promotes plug to return to original state to spring 11 upwards, as shown in figure 1, the second overfall 6 is plugged, overflow passage
It is closed；
When the water outlet pressure of fire pump 1 rises again, repeat the above steps (one), and overflow passage is opened again；
When the water outlet pressure of fire pump 1 declines, repeat the above steps (two)；
So circulation, can realize by pressure release purpose of the overflow passage to fire pump, continue to rise so as to avoid pressure
Height is damaged to fire-fighting pump configuration part and because of damage of the load rise to engine operating, gearbox and power transmission shaft, reduced
Engine energy consumption, extend the service life of fire pump and fire fighting truck.
Finally illustrate, the foregoing is only preferred embodiment of the present utility model, not thereby limit of the present utility model
The scope of the claims, every equivalent structure made using the utility model specification and accompanying drawing content or equivalent flow conversion, or directly
Connect or be used in other related technical areas indirectly, be similarly included in scope of patent protection of the present utility model.
