Description
Technical field
The present invention relates to pure water equipment technical field, specifically a kind of pressure differential switch and pure wetting system.
Background technology
What the water butt of pure wetting system in the market was adopted is Pneumatic pressure water butt, a kind of New Technique of Save on Water in Steam Electric adopts hydraulic type water butt, i.e. water butt is divided into two parts cavity volume, a wherein chamber stores pure water, the condensed water that other chamber storage RO films are emitted is mixed with running water, use for domestic water, now the amount of storage of pure water depends on the pressure of pure water cavity and the pressure differential of running water, if adopting fixation pressure switch control rule mode, when tap water pressure produces fluctuation, the problem of control error is produced easily, when raising more than or equal to pure water operating pressure closing pressure such as tap water pressure, equipment is caused not produce pure water, and then affect the normal use of pure wetting system, cause inconvenience to the user.
The content of the invention
A kind of simple structure of present invention offer, control pressure can be adjusted, stable and reliable in work, cost price is cheap, and can be widely used in various gases, liquid needs to detect pressure differential or controlled the pressure differential switch of occasion and the pure wetting system with the pressure differential switch.
The present invention is achieved through the following technical solutions：
A kind of pressure differential switch，Including upper shell、Lower house、Piston、Upper rubber diaphragm、Lower rubber diaphragm、Rubber diaphragm retaining washer、Spring、Pressure adjusting screw、Lever and microswitch，The upper shell is connected with lower house，The upper shell is provided with water inlet，The lower house is provided with lower water inlet，The spring one end is inconsistent with piston，The other end is inconsistent with pressure adjusting screw by pad，The rubber diaphragm retaining washer is used for connecting rubber diaphragm and lower rubber diaphragm，The piston is located between upper rubber diaphragm and lower rubber diaphragm，The upper shell and the upper pressure chamber of upper rubber diaphragm composition，The lower house and the lower pressure chamber of lower rubber diaphragm composition，The lower house is provided with balance pivot，Described lever one end is connected with piston，The other end is inconsistent with balance pivot，The microswitch is located between upper shell and lower house，And it is inconsistent with lever.
A kind of pure wetting system, including running water inlet, preprocessing filter element, water pump, RO membrane cartridges, pure water takes valve, domestic water valve and water-saving barrel, pipeline between the preprocessing filter element and water pump is provided with entering water electromagnetic valve, the pipeline that the RO membrane cartridges and pure water are taken between valve is provided with rearmounted filter core, the water-saving barrel includes housing, harmomegathus purified water storage bag and concentrated water and running water mixed storage chamber, the shell is provided with concentrated water gateway, tap water inlets and pure water entrance, smart valve is sequentially provided with pipeline between the RO membrane cartridges and concentrated water gateway, choke valve and non-return valve, pipeline between the pure water entrance and tap water inlets is provided with the pressure differential switch.
The preprocessing filter element includes preprocessing filter element A, preprocessing filter element B and preprocessing filter element C, and is connected by pipeline.
The beneficial effect brought of the present invention is：
In the present invention, the pure wetting system with pressure differential switch works in which can ensure that pure wetting system accurate stable, it is to avoid situation out of control.When the harmomegathus purified water storage in water-saving barrel is packed full, pressure in pure water bag is more than the pressure in concentrated water and running water mixed storage chamber, the pressure of pressure chamber is descended now less than the pressure in upper pressure chamber, the piston is moved downward, and then drive one end that lever is connected with piston to move down, lever moves down the switch motion of promotion microswitch and disconnects, and now pure wetting system quits work；When open pure water take valve discharge water use when, the pressure extrusion harmomegathus purified water storage bag of running water in water-saving barrel, pure water is enable to flow out for using, when the pressure in pure water bag reaches design load less than the pressure value in concentrated water and running water mixed storage chamber, the pressure of pressure chamber is descended now more than the pressure in upper pressure chamber, the piston upwards, move on one end that further drive lever is connected with piston, move on lever and promote the switch motion of microswitch and connect, the pure wetting system starts water processed.So ensure that pure water bag stores full pure water all the time and used for user at any time.
