Abstract
The utility model relates to an automatic control valve for water treatment devices. The utility model is mainly composed of an upper cap 1, a lower cover 6 and a control mechanism. The upper cap 1 is provided with a control passage 3. The lower cover 6 is provided with a water inlet passage 5 and a water outlet passage 8. The control mechanism is composed of a valve rod 7, a film piece 4 and a spring 2. The pressure balance principle is applied to the automatic control of the water treatment device. The utility model is safe, and is suitable for matching with various water treatment devices.
Description
The utility model relates to a kind of and the matching used current autocontrol valve of water treatment apparatus.
The existing control valve that is used for water treatment apparatus is solenoid valve, the circulation of the effect controlled water flow by electromagnetic field or pemanent type magnetic material and closing, when practical operation, all electromagnetism need be relied on or manpower is controlled use, be difficult to reach automatic control function, and safety reliability can not be protected.
The purpose of this utility model provides a kind of reliable and practical water treatment autocontrol valve.
The utility model is the autocontrol valve that is used for water treatment apparatus, main by the loam cake 1 that contains control channel 3, contain lower cover 6 into water channel 5 and water outlet way 8, place between loam cake and the lower cover by valve rod 7, diaphragm 4, control mechanism three parts that spring 2 constitutes are formed, autocontrol valve is used for water treatment apparatus, when adding water inlet pressure greater than control saliva source pressure, go into the pressure reduction that produces between water channel and the control channel and overcome spring pressure, the jack-up diaphragm makes into water channel and exhalant canal to be communicated with, and water treatment apparatus carries out working state; When quitting work, water inlet does not have impressed pressure, at this moment, by automatically replying of spring, diaphragm is moved down, and seals into water channel and exhalant canal, enters automatic closed condition.
The utility model reasonable in design, pressure balance principle is applied to the automatic control of water treatment apparatus, overcome the narrow limitation that conventional solenoid valve uses effectively, safe and reliable, easy to use, and can reduce the control switch valve that too much is provided with in the water treatment apparatus, be not subjected to the influence of source pressure height and water source open and-shut mode simultaneously, be suitable for supporting use on all kinds of water treatment apparatus, can also reduce the whole cost of water treatment apparatus.
Accompanying drawing has provided structural representation of the present utility model.
Fig. 1 is the overall structure sectional view of the utility model closed condition.
Fig. 2 is the overall structure sectional view of the utility model circulation status.
Below in conjunction with embodiment the utility model is further described:
The utility model is placed between water source and the water treatment apparatus, and the exhalant canal of lower cover 68 joins with water treatment apparatus, goes into water channel 5 and joins through high-pressure service pump and the water source of impressed pressure, and the then direct and water source of the control channel 3 in the loam cake 1 joins.The water source can be in the unlatching circulation status all the time during use, when high-pressure service pump is opened, current after high-pressure service pump pressurization flow direction control valve go into water channel, go into hydraulic pressure in the water channel 5 this moment greater than the hydraulic pressure in the control channel 3, the pressure reduction that produces overcomes the pressure of spring 2, and jack-up diaphragm 4 drives valve rod 7 and moves on together, make into water channel 5 and exhalant canal 8 to be communicated with, current flow into water treatment apparatus by control valve and handle; When device makes high-pressure service pump close the stopping time by other control units, the current of high-pressure service pump of flowing through do not have impressed pressure, go into hydraulic pressure and control channel 3 interior hydraulic pressure in the water channel 5 this moment and be source pressure under the nature normality, spring 2 is extended automatically replys, drive diaphragm 4 and valve rod 7 and move down, seal, enter automatic closed condition into water channel 5 and exhalant canal 8, this moment, no matter whether the water source opened and closed, and all can not make current enter water treatment apparatus; When Bin gos such as outage took place, high-pressure service pump was closed down, and control valve also can be closed automatically.
