Description
Technical Field
The utility model relates to a liquid level control field, in particular to dual fail-safe fire pond control system that intakes.
Background
The conventional fire pool is provided with two sets of independent perfect automatic hydraulic liquid level control valve groups, when an automatic hydraulic liquid level control valve has a problem, the manual work is used for turning off a maintenance valve in front of the automatic hydraulic liquid level control valve with the problem in the fire pool to maintain the problematic automatic hydraulic liquid level control valve, but if the automatic hydraulic liquid level control valve has no problem, water which is continuous can enter the fire pool and then overflow to the ground, and if the fire pool is arranged in a basement, the basement can be submerged by water.
Disclosure of Invention
The utility model aims at providing a fire pool control system that intakes that occupation space is little, compact structure, has dual fail-safe effect.
In order to achieve the purpose, the utility model adopts the following scheme:
a dual fail-safe fire pool intake control system comprising: the automatic fire-fighting water tank comprises a main water inlet pipe, a valve pipe I, a valve pipe II, a butterfly valve, an expansion joint, a Y-shaped filter, an automatic liquid level control valve I, an automatic liquid level control valve II, an external tank control water tank, a ball float valve, a fire-fighting water tank, a communicating pipe and a communicating valve.
Further, the nominal diameter of the main inlet pipe is 100 mm.
The automatic liquid level control valve is widely applied to automatic water supply systems of various high-low water tanks, water pools and water towers of working condition enterprises, urban and rural buildings and the like, the liquid level is monitored in real time by utilizing the lever type ball float valve, when the liquid level is higher than a threshold value, the valve can be automatically closed to stop water supply, the automatic liquid level control valve is small in size, simple in structure and reliable in performance, but the phenomenon of failure in closing caused by blockage of a valve body due to dirt is particularly noticed.
The Y-shaped filter is a small device for removing a small amount of solid particles in liquid, so that the normal operation of the device can be protected, when fluid enters a filter cylinder with a filter screen with a certain specification, impurities are blocked, clean filtrate is discharged from a filter outlet, and when the filter cylinder needs to be cleaned, the detachable filter cylinder is taken out and is installed again after treatment, so that the Y-shaped filter is very convenient to use and maintain.
The float valve is a valve composed of crank arm and float ball, and can be used to automatically control the liquid level of water tower or pool. The device has the characteristics of simple maintenance, flexibility, durability, high liquid level control accuracy, no water pressure interference on the water level, close opening and closing, no water leakage and the like.
The utility model discloses a show beneficial effect is:
(1) the utility model discloses a two sets of automatic liquid level control valve designs of establishing ties, when an automatic liquid level control valve goes wrong and can't close the valve, another automatic liquid level control valve can also control the pond function of intaking, under the prerequisite that satisfies fire-fighting pond intake and liquid level control requirement, reduces because the probability that the emergence problem of automatic hydraulic power liquid level control valve can lead to the pond overflow.
(2) The utility model discloses to connect pond outer control water tank and fire-fighting water pond through communicating pipe, adopt and utilize U type pipe principle, consequently the liquid level in the pond outer control water tank can truly reflect fire-fighting water pond, guarantees the degree of accuracy of liquid level monitoring.
(3) Traditional ball-cock assembly all sets up in the fire-fighting water pond, and the water that needs unloading fire-fighting water pond when overhauing like this carries out investigation maintenance work volume big, and the consumption time is long, the utility model discloses set up the ball-cock assembly in the pond external control water tank, only need close the intercommunication valve during the maintenance, the water of unloading pond external control water tank just can carry out investigation maintenance work.
(4) The utility model discloses adopt Y type filter at automatic liquid level control valve front end, furthest reduces the possibility that the filth blockked up automatic liquid level control valve.
