Description

Control device for preventing water tank inlet valve from malfunctioning water leakage

Technical Field

The utility model belongs to the plumbing field, concretely relates to prevent controlling means of water tank water intaking valve malfunctioning running water.

Background

At present, most of users of the civil water supply system use tap water which enters a water tank (a water pool) firstly and then is supplied to the users by a booster pump. The existing water tank liquid level control valves are generally provided with one valve or two valves in parallel, and one valve is used for one device.

The water tank water inlet control mostly adopts a remote control ball float valve, and the water tank water inlet control is easy to cause failure or is damaged by water attack due to structural reasons, and once the water tank water inlet control fails, a water leakage accident can be caused no matter one remote control ball float valve or two remote control ball float valves are adopted. Once a water break occurs, the water supply is interrupted or the equipment is damaged by immersion.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a prevent controlling means of water tank water intaking valve malfunctioning running water to the problem of the malfunctioning easy bubble water accident that causes of remote control ball-cock assembly that solves current water tank existence.

The technical scheme of the utility model is that: a control device for preventing water tank inlet valve from malfunctioning and running out of water comprises a standby liquid level control valve and an overflow water tank, wherein the standby liquid level control valve is arranged on a water inlet pipe of the water tank and is connected with a main liquid level control valve on the water inlet pipe in series, a liquid level detection device of the standby liquid level control valve is positioned in the overflow water tank, a liquid inlet pipe and a liquid discharge pipe are arranged on the overflow water tank, and the liquid inlet pipe is communicated with the overflow pipe of the water tank.

As a further improvement, the standby liquid level control valve adopts a remote control float valve, and a floating ball of the remote control float valve is arranged in the overflow water tank.

The utility model has the advantages that: the utility model discloses establish ties a reserve liquid level control valve on original water tank inlet tube, as reserve water intaking valve, establish a little water tank as the overflow water tank again in addition, the water level signal reaction of overflow water tank is opened and close of reserve liquid level control valve. Under the normal condition, the water tank is intake and is main liquid level control valve control, in case main liquid level control valve is out of order, the water tank can overflow, and the water of overflow can get into the overflow water tank, and the liquid level of overflow water tank rises, can make reserve liquid level control valve action and close the water tank at once and intake to realize that main liquid level control valve is out of order and close the effect that the water tank was intake, stopped the emergence of the accident of running water. The utility model discloses a prevent the technological innovation of water leakage occurence of failure back to water intaking valve is the important measure of guaranteeing water supply system safe operation, its simple structure, and the operation is reliable, and the practicality is strong, effectively ensures water supply system's steady operation, guarantees water supply safety.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1-water tank; 101-a water inlet pipe; 2-main level control valve; 3-a standby liquid level control valve; 4-an overflow pipe; 5-an overflow water tank; 501-liquid inlet pipe; 502-drain.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, a control device for preventing water leakage due to water tank inlet valve failure comprises a standby liquid level control valve 3 and an overflow water tank 5, wherein the standby liquid level control valve 3 is arranged on an inlet pipe 101 of the water tank 1, the standby liquid level control valve 3 is connected with a main liquid level control valve 2 on the inlet pipe 101 in series, a liquid level detection device of the standby liquid level control valve 3 is positioned in the overflow water tank 5, a liquid inlet pipe 501 and a liquid discharge pipe 502 are arranged on the overflow water tank 5, the liquid inlet pipe 501 is communicated with an overflow pipe 4 of the water tank 1, and the liquid discharge pipe 502 is communicated with a drainage pool and used for discharging liquid from the overflow water tank 5.

The standby liquid level control valve 3 adopts a remote control float valve, and a float ball of the remote control float valve is arranged in the overflow water tank 5.

The volume of the overflow tank 5 is about 50 liters.

A structure of a water tank commonly used in the prior art can be seen in fig. 1, and a water inlet pipe 101 and an overflow pipe 4 are provided on the water tank 1. The inlet pipe 101 is provided with a main liquid level control valve 2, which is generally a remote control float valve. The overflow pipe 4 leads to a drainage basin. In case the main level control valve 2 fails, a water run-out accident may occur.

The utility model discloses a set up overflow tank 5 and reserve liquid level control valve 3 and can prevent the water leakage accident that leads to because of main liquid level control valve 2. The main liquid level control valve 2 and the standby liquid level control valve 3 (the same type and the same specification) are connected in series on a water inlet pipe 101 of the water tank 1, the main liquid level control valve 2 controls water inlet of the water tank 1, and the standby liquid level control valve 3 controls the operation of the overflow water tank 5 by a water level signal. The inlet pipe 501 of the overflow tank 5 is communicated with the overflow pipe 4 of the tank 1, and the inlet water of the overflow tank 5 comes from the overflow of the tank 1. Under the normal condition, water tank 1 is intake and is main liquid level control valve 2 control, in case main liquid level control valve 2 is out of order, water tank 1 can overflow and get into overflow pipe 4, the water of overflow can get into overflow water tank 5 through feed liquor pipe 501, the liquid level of overflow water tank 5 rises, can make reserve liquid level control valve 3 action and close water tank 1 and intake at once, thereby realize that main liquid level control valve 2 is out of order and close the effect that water tank 1 was intake, the emergence of the accident of having stopped running water.

The utility model discloses simple structure, simple to operate, operation are reliable, are suitable for the safety control that all water tanks intake, can thoroughly prevent the emergence of the water leakage accident that causes because of the failure of water tank water intaking valve.
