Abstract
It is composed of casing body, check valve, pressure switch and front valve on the outlet pipe. Elastic check valve is fitted in the inlet pipe within the casing body, and the structure of the check valve features that the linking stem of valve lid is inserted in the valve body and is sleeved with a pressure spring externally, of which the front part is pinned with a fixing ring. The pressure valve inter linked with pump motor is fitted on the upper side of inlet pipe outside the casing body, and is fixed on the casing body with a fixing screw and is connected to the pressure in casing body, and there is a valve in front part of outlet pipe. Two half-cases can be welded to form the casing body at folded edges, inlet and outlet pipes are screw-jointed, and the elastic check valve is fitted in the joint of inlet pipe.
Description
The invention belongs to Yi Jing, river, river, lake water is the water source.Give in the electronic water supply system, the design and the manufacturing technology field of the control device of cutting off the water.
In no tap water area, what have draws drinkable water with electric pump from well at present.Need to place the storage tank that volume is very big in indoor eminence, concentrated water storage uses by stages.This is promptly inconvenient, and expense is high again.When carrying out field irrigation with drawing water in the electric pump Congjiang, river, lake, the pool, the water inlet pipe of water pump places water (submersible pump places water if draw water then with submersible pump), outlet pipe reaches the irrigated area away from electric pump, the pump of opening, have a power failure is very inconvenient, the wet pin of the often wet hand of operating personnel, the touching electric switch is dangerous.
The objective of the invention is, the defective at existing electronic feed water control system provides a kind of simple in structure, electronic feedwater controller easy to use.
The present invention is achieved through the following technical solutions:
In the pressure controller housing, in the water inlet pipe elastic force non retern valve is housed, the outer water inlet pipe upside of housing is equipped with a pressure control switch with the pump motor interlocked control, and this pressure control switch communicates with the housing internal pressure.Elastic force non retern valve and pressure control switch are controlled by current and the interior hydraulic pressure of housing, carry out action separately.There is a valve outlet pipe front portion, this valve controlled water flow and hydraulic pressure.Be the switch control elastic force non retern valve of valve and the action of pressure control switch, reach to, the purpose of cutting off the water.
Structure of the present invention as shown in drawings.Valve by housing, elastic force non retern valve, pressure control switch and outlet pipe front portion is formed.
Housing (1) is made up of half shell of two punching stretch formings.Two and half shell flange places are connected by bolt (11), and a sealing ring (10) is arranged between two flange.Adorn an elastic force non retern valve in the admitting pipe joint in the housing (1).The elastic force non retern valve is made up of valve body (2), connecting rod valve gap (3), pin (4), back-up ring (5) and compression spring (6).Structural relation between each parts is:
The connecting rod of connecting rod valve gap (3) inserts in the valve body (2), a compression spring of valve gap connecting rod sleeve (6), and a back-up ring (5) is fixed by pin (4) in valve gap connecting rod front portion, in order to the retaining compression spring.Housing (1) outside, water inlet pipe upside are adorned one by lead and the pump motor pressure control switch of interlocked control (7) mutually, and this switch passes sealing mat (8) by hold-down screw (9) and is fixed on the housing (1).In pressure control switch (7) and the housing (1) the pressure communication hole is arranged, there is a valve outlet pipe front portion.Two and half shells also can be in flange place welding, and inlet tube and outlet tube and housing (1) are used screwed connection, and wherein admitting pipe joint is packed into and is connected with housing (1) behind the non retern valve.
Operating principle of the present invention is:
The hydraulic pressure that has pressure from the water pump spring that contracts makes connecting rod valve gap breakdown, and water flows in the housing, delivers to the water place by outlet pipe again.When with outlet pipe front portion valve closing, water pump continues to feed water in housing, causes the interior hydraulic pressure of housing to increase, and the connecting rod valve gap is closed.Pressure control switch begins action because of superpressure, and motor switches off the pump.During water, with the anterior valve breakdown of outlet pipe, water begins to flow out in the housing, makes the housing internal pressure be brought down below authorized pressure (as 0.2MPa), and this moment, pressure control switch began action, made the electronic rotation of water pump, to the housing inner water-supply.Operation is so repeatedly controlled to, the operation of cutting off the water.
The material of housing is the cold roiled steel plate, and its manufacture method has two kinds: the one, and punching stretch forming connects with bolt at the two and half shell places of rebuilding or renovate.The 2nd, by the cableties border, the two halves shell welds at the flange place between punch forming two and half shells and the water-in and water-out union, itself and housing.The material of non retern valve is good (the some of them parts can adopt monomer cast nylon or engineering plastics) with brass, needs to press the processing and manufacturing of accompanying drawing structure.Pressure control switch can adopt the commercially available prod.Processing is purchased above-mentioned parts, is assembled and be pressure control type motor driven water supply.
Using method of the present invention is:
To draw well water is that drinkable water is an example.The water inlet pipe of submersible pump or ground pump is placed well water, and the outlet pipe of pump and the admitting pipe joint of electronic feedwater controller join, and using first needs to start earlier pump motor, via controller is to indoor water-supply, flowed out by the anterior valve of outlet pipe, as with this valve closing, water pump promptly stops feedwater.Opening a lower valve during water again gets final product.The diversion irrigation using method therewith roughly the same in the Congjiang, river, lake, the pool.The pipeline that joins with controller water-in and water-out union, with flange, screwed connection all can, but if use rubber tube or plastic pipe socket.
Advantage of the present invention is, simple in structure, volume is very little, makes easily and keeps in repair, and is easy to use, and sensitive reliable, applicability is wide, and cost is low.
Accompanying drawing is a structural representation of the present invention
1-housing, 2-valve body, 3-connecting rod valve gap, 4-pin, 5-back-up ring, 6-compression spring, 7-pressure control switch, 8-sealing mat, 9-hold-down screw, 10-sealing ring, 11-bolt
