Description

Pressure-stabilizing remote-control float valve

Technical Field

The utility model relates to a liquid level control valve, especially to the remote control ball-cock assembly of water tank control of intaking.

Background

At present, a secondary booster pump station mostly adopts a water storage tank water storage and supply mode, and a water inlet control valve of a water tank is automatically controlled by using a traditional ball float valve or a remote control ball float valve. The control principle is as follows: the floating ball is used for controlling the valve to be opened and closed, the floating ball changes along with the change of the liquid level of the water tank, and the valve is opened when the liquid level of the water tank slightly drops; when the liquid level of the water tank slightly rises, the liquid level of the floating ball reaches the highest liquid level and the valve is closed, so that the liquid level of the water tank is in a higher position for a long time, water stored in the water tank cannot be utilized and replaced, and the risk that the water stored in the water tank goes bad is increased.

Because the bore of remote control ball-cock assembly is generally great, or install and be less than conventional direct water supply end position in basement etc. and put, the remote control ball-cock assembly of water tank import can all be in full open or large-traffic water supply state when the water peak period, and the remote control ball-cock assembly will occupy a large amount of water sources this moment, has seriously reduced the pressure of municipal pipe network, has influenced municipal direct water supply end and other low reaches water, also is very big investigation to the water delivery capacity of pipe network and the system water ability of water utilities company simultaneously.

At present, the market also has a technical scheme capable of solving the defects. For example, patent application numbers 201810503312.2 and 201810014242.4 disclose a series of electrical devices based on electric valves, sensors, controllers, etc. to solve the problems of the float valve in use. However, the functions of the equipment are mainly realized by utilizing more complex and more electric devices and electric signal transmission control, and the equipment cannot normally work due to factors such as environmental interference, power failure and the like of the electric equipment, so that the equipment is troublesome in production, manufacture, installation and use, and particularly has the fatal defect that a power supply cannot be disconnected in use.

Though the invention of the patent application No. 201910125579.7 of the inventor solves the problems, the pressure-holding liquid level upper and lower limit control valve is not ideal enough in the use of large-flow water supply or large-caliber pipe valves, and has the problems of high manufacturing cost, large volume, inconvenience in mounting on a water tank port, poor universality and the like.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a simple structure, the stable performance need not the pure mechanical type remote control ball-cock assembly of electrical part and power, toward the water tank moisturizing again under the long-time stable pressure's of assurance income water pipe network prerequisite, and furthest has ensured municipal pipe network steady voltage and water tank maximum water source and has updated to and make water supply pipe network realize the off-peak water supply.

The utility model provides an above technical problem adopt be following technical scheme:

the main components of the float valve are a traditional hydraulic control valve, a traditional pressure reducing valve, a self-closing valve and a pressure-holding hydraulic level upper and lower limit control valve of the invention patent application No. 201910125579.7 of the inventor.
