Description

With the remote control float valve device for protecting and automatically controlling flow of inlet water

Technical field

It is especially a kind of with the remote control floating ball for protecting and automatically controlling flow of inlet water the utility model relates to valve field Valve gear.

Background technique

Remote control float valve is that a kind of control liquid level that is widely used is maintained at the valve of certain altitude, and when work is matched by itself Buoyancy of the floating ball by liquid is covered, and then under associated mechanisms effect, the input or cut-off of liquid are inputted on controlling brancher, When liquid level is low in container, feed liquor spool is opened inside remote control float valve, so that liquid is floating through liquid feeding end, the spool of opening, remote control The outlet end of ball valve flows out, and when liquid level is high in container, feed liquor spool is closed inside remote control float valve, thus liquid do not enter back into it is distant It controls inside ball-cock assembly, liquid in container can thus be kept to be constantly in suitable height；In practical operation, by manually adjusting The regulating valve stem front end regulation handle of the mating needle valve mechanism of remote control float valve can be controlled under the effect of needle valve mechanism internal mechanism The feed liquor flow of remote control float valve liquid feeding end processed, when the regulation handle of needle valve mechanism rotates to the left, remote control float valve liquid feeding end Feed liquor flow reduces, and when the regulation handle of needle valve mechanism rotates to the right, the feed liquor flow of remote control float valve liquid feeding end increases (needle-valve The spool of mechanism is off spool or butterfly valve core).When the spool of needle valve mechanism is off spool (after cut-off valve core rotation multi-turn Contact or separation of the valve seat with spool just can be realized, to realize the closing and opening of spool) under the action of regulating valve stem, After the regulation handle of needle valve mechanism rotates clockwise multi-turn, the valve seat distance for ending spool and needle valve mechanism is close, to be remotely controlled The feed liquor flow of ball-cock assembly liquid feeding end reduces, and after multi-turn rotation that the regulation handle of needle valve mechanism is counterclockwise, ends spool and needle-valve The valve seat distance of mechanism zooms out, so that the feed liquor flow of remote control float valve liquid feeding end increases；The spool of needle valve mechanism is butterfly valve valve (butterfly valve core rotation is no more than 360 degree and contact or separation of the valve seat with spool can be realized, to realize the closing of spool when core Or open) under the action of regulating valve stem, the regulation handle of needle valve mechanism is rotated clockwise no more than 360 degree, butterfly valve core with The valve seat distance of needle valve mechanism is close, so that the feed liquor flow of remote control float valve liquid feeding end reduces, the regulation handle of needle valve mechanism Rotation is no more than 360 degree counterclockwise, and the valve seat distance for ending spool and needle valve mechanism zooms out, thus remote control float valve liquid feeding end Feed liquor flow increases.(the feed liquor outlet end of remote control float valve itself has spool valve seat etc., the needle-valve machine of remote control float valve itself Structure has another set of valve seat, spool etc.).

Skyscraper secondary water supply system, working method are by water tank water, and booster pump supply equipment is by water in water tank Extraction is pressurized, and being then input to high-rise buildings makes the just common water of user.When secondary water supply system works, and municipal administration is originally Pipe network be connected positioned at the remote control float valve of water tank upper end water level is not at peak level in water tank when, inner spool always can It is in the open state to inject water in water tank, cannot reduce when municipal tap water pipe network water pressure is lower than a certain range input from Carrying out water flow, (in actual use, the regulation handle of the remote control float valve that secondary water supply system uses, needle valve mechanism is pre-adjusted In place, in this way, remote control float valve is generally held in big flow water inlet state when intaking, the regulation handle of needle valve mechanism cannot be adjusted Save too small, adjust that the too small water consumption that will lead to is excessive, and remote control float valve water inlet is too small is needed without being able to satisfy user with water), this Sample, if the hydraulic pressure of municipal tap water pipe network is reduced to certain value, since the spool opening of valve is constantly in big flow water intaking State, the hydraulic pressure that but will aggravate in the pipe network of municipal tap water reduce, and cause remaining user that cannot just commonly use water；Actually due to water Moisture storage capacity in case is larger, without moisturizing or small flow moisturizing within city planting ductwork hydraulic pressure too low a period of time, not shadow It rings the user to supply water through booster pump supply equipment and just commonly uses water in for a period of time.

Based on above-mentioned, provide it is a kind of be in the water use peak phase in municipal tap water pipe network, hydraulic pressure value is reduced to certain valve afterwards Core can be automatically closed closes to a certain degree or all, reduces or stop to carry out moisturizing for the water tank of booster pump supply equipment, in city After political affairs tap water pipe network hydraulic pressure restores normal, can carry out the remote control float valve door that big flow is water tank progress moisturizing automatically seems It is particularly necessary.

Utility model content
