The beneficial effects of the utility model are:

Water-hammer arrester of the present utility model is when fire_fighting pipe network pressure is lower than design pressure, and immediately to pipe network water filling voltage stabilizing, when ductwork pressure is higher than design pressure, draining pressure release immediately, ensures that pipe network fluctuates in the pressure range of setting, ensure system safety operation.

The utility model is connected with high-order fire water tank, decreases the retention volume of conventional water hammer cancellation element, and utilize the pressure of high-order fire water tank to carry out voltage stabilizing setting, reduce the volume of pressure stabilizing cavity, floor space is little simultaneously.

It is all the mode adopting spring or diaphragm voltage stabilizing that the utility model changes conventional water hammer cancellation element simultaneously, only carries out the adjustment of system pressure with spring, makes system more stable.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model water-hammer arrester;

In figure, 1-valve, 2-safety check, 3-PRESSURE PIPE, 4-valve plate, 5-pressure-releasing chamber, 6-sealing plate, the spring sealed piston of 7-, 8-pressure stabilizing cavity, 9-pressure adjusting knob, 10-first pipeline, 11-second pipeline, 12-the 3rd pipeline.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figure 1, the water-hammer arrester that temporary high-pressure fire-fighting system is special, comprise the first pipeline 10 (DN50) be communicated with elevated tank voltage-stabiliser tube, first pipeline 10 is communicated with pressure stabilizing cavity 8 by PRESSURE PIPE 3, pressure stabilizing cavity 8 bottom connects pressure-releasing chamber 5, the top of pressure stabilizing cavity 8 and pressure-releasing chamber 5 joint is provided with sealing plate 6, sealing plate 6 bottom linking springs packed-piston 7, spring sealed piston 7 bottom is connected with valve plate 4, Bonding pressure adjusting knob 9 above sealing plate 6, pressure adjusting knob 9 stretches out outside pressure stabilizing cavity 8, is convenient to regulate; Pressure-releasing chamber 5 is by the second pipeline 11 (DN100) communicated drainage passage; Valve plate 4 bottom is the 3rd pipeline 12 (DN50), is connected with fire_fighting pipe network; First pipeline 10 is connected with the 3rd pipeline 12, and is provided with safety check 2 on the first pipeline 10.On 3rd pipeline 12 and be provided with valve 1 between fire_fighting pipe network.

Drainage pipe is fire-water pond or gutter.

Second pipeline 11 is equipped with seal element with pressure-releasing chamber 5 joint, valve 1 and the 3rd pipeline 12 joint, safety check 2 and the second pipeline 11 joint.Be provided with seal element in pressure stabilizing cavity 8 to match with pressure adjusting knob 9, seal element center is provided with through hole, passes for pressure adjusting knob 9, the size of through hole and the cross-sectional dimension of pressure adjusting knob 9 suitable.

After water-hammer arrester of the present utility model installs, valve 1 is often opened, and closes during maintenance, by PRESSURE PIPE 3, the pressure of elevated tank is imported pressure stabilizing cavity 8, now, pressure stabilizing cavity 8 internal pressure is identical with the 3rd pipeline 12 pressure, rotary pressure adjusting knob 9, compression seal plate 6 and spring sealed piston 7, pass through spring-compressed, increase the pressure to valve plate 4, until pressure increase is to the breakout pressure of the valve plate 4 needed, now breakout pressure is set as the numerical value needed.

This device is located on the fire main of exit of pump, if there is no this device, the moment of water pump termination of pumping, the current of pump outlet continue upwards to flow according to inertia, but water pump now no longer water outlet, therefore produce negative pressure, (simple negative pressure is on pipeline no impact herein, but negative pressure generated value is higher, the malleation that the later stage rebounds back is higher, therefore needs water filling to cut down negative pressure.) after current lose inertia, will flow backwards, flow backward to pump outlet, blocked by safety check, will malleation be produced.(pressure that this positive pressure pressure can reach 300 ~ 400 meter water columns in fire-fighting system is even higher, exceed pipeline ability to bear, therefore pressure release is needed) from water pump termination of pumping to the generation malleation only 1s time, general pressure relief device has time delay, is not suitable for fire-fighting system.

When water pump termination of pumping or the unexpected pressure release of fire_fighting pipe network, pipe network water hammer produces suction wave, and fire_fighting pipe network pressure is lower than the force value of elevated tank, safety check 2 is opened, to pipe network water filling voltage stabilizing, because valve plate 4 place pressure is closed higher than the pressure of elevated tank, current inject pipe network.

When water pump termination of pumping or pipe network generation Hydraulic Transient, pipe network water hammer produces barotropic wave, and when the force value of pressure higher than elevated tank, safety check 2 cuts out, and when now ductwork pressure is still lower than setting value, valve plate 4 is closed, and is failure to actuate; When barotropic wave pressure is higher than setting value, valve plate 4 moves upward unlatching, and pipe network water flows to into pressure-releasing chamber 5, then drains.

The utility model adds the connecting tube with fire-fighting system elevated tank on water-hammer arrester, and the system that ensure that, can to water filling in system when there is negative pressure, stable system pressure, when system pressure exceedes valve setting values, and valve open, sluicing voltage stabilizing.The utility model needs roof elevated tank voltage stabilizing, is applicable to tall building temporary high pressure fire control water supply system.

By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
