Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of pressure controller.
Background technique
The electric water pump that uses at present in order to realize automatic control, is provided with electronic pressure controller in pipeline.When pressure reaches the maximum pressure value of water pump, and continue 10 seconds left and right sides time, pressure controller is just controlled water pump and is quit work, the waste electric energy; When pressure drops to the starting mode of pump of pressure controller control in limited time under the setting value.
This pressure controller can not arrange the upper limits pressure of pressure controller, and continues for some time (about 10 seconds) and just can close, and it is to utilize the maximum pressure value of water pump as the upper limits pressure of pressure controller.
That is to say when pressure has reached the maximum pressure value of water pump, and continue 10 seconds left and right sides time, pressure controller just can be controlled water pump and quit work.The time that can cause like this it to arrive water pump maximum pressure value is longer, the waste electric energy, and also the maximum pressure value that can bear of the joint of pipeline opening causes the pipeline joint damaged much smaller than the maximum pressure value of water pump easily, causes the generation of leaking.After leaking generation, the pressure in the pipeline just can not reach the maximum pressure value of water pump, and pressure controller can not be controlled water pump and quit work, and causes waste, and pressure controller lost efficacy.In addition, electronic pressure controller in working order in, when flow hour, electronic pressure controller is just worked always, controller can not closed, and can cause like this water pump to burn easily in the high pressure situation.
For this reason, people have adopted the mechanical pressure controller, and most of mechanical pressure controller does not dispose the excessive low water level protection structure.When the water source is drained, just no longer include current in the pipeline and enter, the pressure in the pipeline is lower than the maximum pressure value of water pump, and pressure controller is being controlled water pump always and is being made the water pump continuous firing.This moment, electric water pump was in the dry running state, wasted to a certain extent electric energy, and the water pump under the dry running state can produce amount of heat, caused water pump component softening transform, made the wearing and tearing aggravation between the component, had greatly shortened the working life of water pump.For avoiding the generation of water pump no load running, need workers with long time on duty, increase labour cost.
Mechanical switch on the market has a fatal weakness: when the pressure of water pump reaches between switch upper pressure limit and the lower limit, switch can not cut out, and can cause the long idle work of water pump, even can cause water pump to burn.And the mechanical switch on the market all needs to dispose a water storage tank in addition, and it is large to cause taking up room, and cost is high.
Summary of the invention
The objective of the invention is to have the problems referred to above for existing technology, proposed a kind of when reaching controller upper pressure limit value moment disconnect, have the excessive low water level protection function, at the pressure controller of can the autoshutdown water pump in without the situation of flow below the controller setting pressure CLV ceiling limit value, below controller setting pressure CLV ceiling limit value, working when more than the lower limit flow being arranged.
Purpose of the present invention can realize by following technical proposal:
A kind of pressure controller; comprise that upper side has the base of dunnage; be located at the protective cover of base top and be located at the valve seat with valve pocket that is communicated with water pump of being used for of base downside; described dunnage is provided with fixed contact; the upper side of described base is hinged with mobile plate; has the movable contact that is oppositely arranged with above-mentioned fixed contact on the described mobile plate; it is characterized in that; the downside of described base is provided with for the Inductance valve cavity pressure and with this force value and is delivered to induction structure on the above-mentioned mobile plate; described valve pocket is communicated with this induction structure, also is provided with the regulator for limits pressure and threshold pression on this pressure controller of adjusting on the described base.
In above-mentioned pressure controller, described mobile plate comprises upper movable part and the lower movable part that is hinged on the base, described movable contact is arranged on the movable end of movable part on this, and described upper movable part is connected by an elastic component with this time movable part, can drive the movable contact of described upper movable part to the direction motion away from fixed contact when the movable end of described lower movable part moves upward.
Behind starting mode of pump, the water pump normal operation, current enter in the valve seat, and the pressure rise in the valve seat transfers the pressure on the lower movable part by inductor.When upper limits pressure that this pressure rise is set to pressure controller, the movable end of lower movable part moves upward, thereby the movable end that drives upper movable part moves to the direction away from fixed contact, and movable contact separates with fixed contact, the loop of control pump working disconnects, and water pump quits work; When threshold pression that this pressure drop is set to pressure controller, the movable end of lower movable part moves downward, thereby the mobile plate that drives upper movable part moves to the direction near fixed contact, and movable contact contacts with fixed contact, the circuit closed of control pump working, water pump is started working.The upper pressure limit value of this regulator adjustable pressure controller and low pressure limit value, simple to operate, easy to adjust.
This protective cover is protected the component of being located on the base, prevents that electric shock accidents from occuring, the protection personal safety.
In above-mentioned pressure controller, the movable end of described lower movable part is provided with through hole, above-mentioned regulator comprises the screw rod of vertically being located in this through hole, the bar head of described screw rod is fixed on the above-mentioned base, be arranged with successively spring element and nut on the described screw rod, one end of described spring element acts on the above-mentioned lower movable part, and the other end of described spring element acts on the nut.
