Abstract

A liquid level remote control method comprises an infusion tube with a valve and a liquid level exploring tube with an opening down-facing arranged in a container, wherein, the liquid level exploring tube is connected to one infusion tube that is connected to one end of a U-shaped tube of a communicating vessel with quantitative liquid, and the other end of U-shaped tube is provided with a liquid level switch. The valve infusing to the container achieves control by using remote atmospheric pressure resulted from the rising level of one end of U-shaped tube to lead to the other end to change and generate signals, thus while filling flammable liquid, electrical components that are easy to trigger fire are not used or shifted to the distant security zone, and the float valve of high-level water towers and solar heaters, etc. which is to be installed in the height originally moves to such areas where people are easier to control and repair.

Description

Liquid level remote-control method

Technical field

A kind of remote-control method, especially liquid level remote-control method.

Background technology

The Long-distance Control of level switch, normal at present the employing placed electrode in controlled liquid, electrode produces through liquid and conducts when liquid level rises, and conducting signal electric current is wired to relay coil at a distance, make relay work, control the method for transfuse switch by relay contact.And the shortcoming of this kind method is a liquid must be electric conductor, if paint, flammable liquids such as solvent, generally can only control the transfusion valve by the liquid level in the linker of range estimation liquid storage tube outside or from jar bung range estimation liquid level, as: after tank train arrives at a station, in order to unload as early as possible, enterprise carries out packing with petroleum can at the station of will sending someone, divide all petroleum cans of the general loading amount of barrelling at 200Kg, when the tank car that deoils with this oil drum connects jar gasoline equal solvent, generally can not divide filling place all to use volume pump at each, also can not all move every barrel of oil to fixing platform scale position gets on to weigh, because it is so very time-consuming, the station has little time turnover, decides closing of oil drain cock to open so mainly observe level condition by human eye from the drain line residue slit of jar hydraulic fluid port, but takes eyesight very much, in case error, oil is let out full ground, causes fire easily, and the accident that causes big fire to be stretched AT STATION because of the excessive ground of gasoline also once took place in the past in Jiaxing unit.And for example: the producer that produces paint, the lacquer of producing from reactor, generally should filter as early as possible with canned, because volume pump is very easy to be clung by lacquer, decide closing of valve to open so also all lean on human eye to observe the interior liquid level of bucket usually from the jar bung, this does not only see, and also makes toxic gas invade human body, damages.In addition, if liquid is the water of conduction, as with solenoid control sometimes because of act frequently, power consumption etc. is former improper for some reason, but come control water level with existing ball-cock assembly, its shortcoming is that ball-cock assembly must drop in the water tank, as roof solar water heater or high-rise water tower, generally all inconvenience is used, because in case malfunctioning must climbing.

Summary of the invention

The objective of the invention is: release a kind of especially flammable body fluid of signal position rising signal transmission of liquid level being risen and reach at a distance, and control the liquid filling valve door with this signal and close the method that opens.

The object of the present invention is achieved like this: it comprises that a valvular woven hose of installation and an opening are placed on the dip tube in the container down, sound-pipe connects a gas piping, gas piping is connected on the termination of the linker U type pipe that is placed with quantitative liquid, the other end of U type pipe is equipped with level switch, it is characterized in that: to the valve of container transfusion is to utilize U type Guan Zhongyi end to be subjected to that tank fill level rises and the teletransmission air pressure that produces, and the signal that other end liquid level change is produced is realized controlling.

Like this when container is irritated liquid, liquid level rises in the container, air in the liquid level compression sound-pipe, this pressurized air arrives U type Guan Yiduan through the gas piping teletransmission, the liquid level of the other end changes in the U type pipe, the liquid level that rises is by the liquid level change in sound-pipe, gas piping and the U type pipe, can directly drive ball-cock assembly or utilize common liquid level such as contact, photo-electric, magneto-electric to pass element, the liquid level signal is passed to the people or the motor drive mechanism of control transfusion valve, transfusion is promptly stopped, therefore do not need to gaze at liquid level, bring great convenience to the staff.And because gas piping can be done not only longly but also thin, so U type pipe and operation valve can put to such an extent that irritate the far safety zone of flammable liquid from dress, even operation valve adopts electronic control like this, electric spark can not cause fire yet.Measure-alike or when indicating fixed volume for being irritated container shapes, can also fix the degree of depth of sound-pipe and bung, when utilizing liquid level to rise to valve to close automatically, liquid level rests on the characteristics of same position at every turn in the bucket, carries out the general quantitative filling liquid of fluent material.Resemble the water inlet of solar water heater or high-rise water tower in addition, utilize the control method of U type pipe, just ball float can be moved on to the place of handled easily and repairing, also do not need electricity consumption to go control.
