Abstract
The utility model provides a kind of pressure limiting gas-liquid control valve on fire water gun carriage, comprise the water tank of fire water gun carriage, be provided with water inlet bottom water tank, the top of water tank is provided with outlet pipe, outlet pipe is provided with control valve, and described control valve is connected with energy storage tank by high-pressure air pipe; Energy storage tank is nitrogen energy storage tank, and energy storage tank inside is divided into two parts, and centre barrier film separates, and the part be connected with high-pressure air pipe is that nitrogen stores space, and another part is full of air; The pressure of the inner nitrogen of energy storage tank is 3-6Mpa; Energy storage tank top is provided with inflation inlet and Pressure gauge.The pressure of gas or liquid in energy storage tank is utilized to be supplied to control valve in the utility model, the pressure limit value of control valve so just can be made larger, and controlled, rational control is carried out to the inside water pressure of high pressure fire fighting deluge camion, has ensured the use of high hydraulic pressure and wide range.
Description
Technical field
The utility model relates to the parts on fire water gun carriage, specifically a kind of pressure limiting gas-liquid control valve on fire water gun carriage.
Background technology
Publication number is CN 201505384 U super-pressure height spray fire water gun carriage supercharging waterworks, comprise power set, hydraulic oil pump, reversal valve, double piston-rod double acting liquid oil cylinder, Bidirectional supercharging water delivery cylinder and piston, Inlet and outlet water check valve, water turbine pumps, hydraulic oil pump is connected with reversal valve by high-pressure oil pipe, hydraulic oil is alternately injected double piston-rod two-way cylinder by reversal valve, double piston-rod two-way cylinder piston driving two ends supercharging water delivery cylinder reciprocating motion of the pistons, water under high pressure connects the press-in pressure piping that continues and is sent to by water turbine pumps the fire demand water demand that special high scooter meets the fire extinguishing of super-high buildings exterior wall, also implement external high pressure by high-rise building combined outside device and lead directly to high-rise water supply, solve the anhydrous difficult problem supplied of high-rise building high level fire fighting.
Its difficulty is: it is higher that double piston-rod two-way cylinder and independent oil circuit realize cost, and need to reach certain volume could realize described in power.
Need certain pressure that it just can be made to ensure certain water yield for its delivery port, common pressure switch cannot realize the pressure of 3-6Mpa.
Summary of the invention
The utility model is in order to ensure that fire water monitor delivery port has stable pressure, and ensure water yield, spy provides a kind of pressure limiting gas-liquid control valve on fire water gun carriage.
The technical solution of the utility model is for this reason, a kind of pressure limiting gas-liquid control valve on fire water gun carriage,
Comprise the water tank of fire water gun carriage, be provided with water inlet bottom water tank, the top of water tank is provided with outlet pipe, it is characterized in that: on outlet pipe, be provided with control valve, and described control valve is connected with energy storage tank by high-pressure air pipe.
Further improvement is: energy storage tank is nitrogen energy storage tank, and energy storage tank inside is divided into two parts, and centre barrier film separates, and the part be connected with high-pressure air pipe is that nitrogen stores space, and another part is full of air.
Further improvement is: the pressure of the inner nitrogen of energy storage tank is 3-6Mpa.
Further improvement is: energy storage tank top is provided with inflation inlet and Pressure gauge.
Beneficial effect:
Utilize the pressure of gas or liquid in energy storage tank to be supplied to control valve in the utility model, the pressure limit value of control valve so just can be made comparatively large, and controlled.
Nitrogen accumulation of energy uses more for convenience, the use of medial septum is in order to when the pressure of control valve is when being greater than setting value, barrier film facilitates protruding accumulation of energy to air, the outlet pipe of fire water gun carriage is opened, and can carry out operation, when the pressure of control valve is when being less than setting value, barrier film releases energy to nitrogen direction and to be closed by control valve, to be that the hydraulic pressure of energy storage tank rises, to facilitate fire water gun carriage to have a stable hydraulic pressure release always, thus reach the fire demand water of high hydraulic pressure wide range.
The nitrogen pressure of 3-6Mpa is a rational safe air pressure for fire water sport car.
Energy storage tank top is provided with inflation inlet and Pressure gauge conveniently inflates and observes, and plays the effect of safety inflated.
The utility model has carried out rational control to the inside water pressure of high pressure fire fighting deluge camion, ensures the use of high hydraulic pressure and wide range.
Accompanying drawing explanation
Fig. 1 is syndeton schematic diagram of the present utility model.
In figure, 1 is water tank, and 2 is water inlets, and 3 is outlet pipes, and 4 is air, and 5 is barrier films, and 6 is nitrogen, and 7 is high-pressure air pipes, and 8 is control valves, and 9 is inflation inlets, and 10 is Pressure gauges, and 11 is energy storage tanks.
Detailed description of the invention
The utility model as shown in Figure 1.
A kind of pressure limiting gas-liquid control valve on fire water gun carriage, comprise the water tank 1 of fire water gun carriage, be provided with water inlet 2 bottom water tank, the top of water tank 1 is provided with outlet pipe 3, outlet pipe 3 is provided with control valve 8, and described control valve 8 is connected with energy storage tank 11 by high-pressure air pipe 7.
Energy storage tank 11 is nitrogen energy storage tank, and energy storage tank 11 inside is divided into two parts, and centre barrier film 5 separates, and the part be connected with high-pressure air pipe 7 is that nitrogen 6 stores space, and another part is full of air 4.
The pressure of the inner nitrogen 6 of energy storage tank 11 is 3-6Mpa, and pressure adjustable joint, so that the building being used in differing heights uses.
Energy storage tank 11 top is provided with inflation inlet 9 and Pressure gauge 10.
