Abstract
The utility model discloses a domestic water supplying device, which is composed of a water pump, a water tap, a switch for controlling the on-off of the water pump and a control circuit of the switch. A contact of the switch is contacted with the surface of a valve rod of the water tap, the valve rod of the water tap is provided with a section of curved surface with a gradually changing radius, and the contact does reciprocating extending or retracting motion following the upward and downward rotation of the valve rod so that the utility model achieves the action of opening or closing the switch to control the on-off of the water pump. The domestic water supplying device is mainly used for supplying water to families and irrigating trees and solves the defect that the prior art has frequent start and easy damage when the prior art supplies water with small flow, and the utility model is a water supplying device with simple structure, convenient use and long service life.
Description
What the utility model related to is a kind of water supply installation that low discharge supplies water that is suitable for.
At present water supply installation has two kinds of fluid pressure type and vapour-pressure types, with the vapour-pressure type is main flow, the vapour-pressure type water supply installation is realized automatic water-supply with a several pressurized tank and pressure switches that rise to several decaliters of volume, open valve, water retention capacity in the pressurized tank reduces, thereby pressure descends, when reducing to certain value, and the pressure switch adhesive, directly start water pump, realize continuously behind the starting mode of pump supplying water, when valve-off, the water yield of water pump all stores in pressurized tank, along with the water yield in the pressurized tank increases, force value raises, and when reaching certain value, pressure switch disconnects, directly switch off the pump, gas in the gas tank generally replenishes by making-up air device and keeps constant basis, otherwise the gas in the pressurized tank is fewer and feweri, causes regulated quantity fewer and feweri; The fluid pressure type water supply installation utilizes the variation of hydraulic cylinder volume and travel switch to realize control automatically, and cylinder body does not have air, and regulated quantity is directly proportional with the cylinder body size.When family etc. needs low discharge to supply water, utilize said apparatus just very uneconomical, the vapour-pressure type device volume is big, the making-up air device complexity is easy care not, and the regulated quantity of fluid pressure type device is directly proportional with manufacturing cost, and the hydraulic cylinder in the practicality can not be done very greatly, therefore these two kinds of water supply installations are when low discharge supplies water, the capital makes the water pump frequent starting, and pressure switch and water pump damage easily, is unfavorable for the safe handling of whole system.
The purpose of this utility model is to provide that a kind of security performance is good, long service life be suitable for the water supply installation that low discharge supplies water.
The utility model is achieved through the following technical solutions, and it is made up of switch and control circuit thereof that water pump, water tap, control of pump open and close, and the contact of switch contacts with the valve rod curved surface of tap, and leading valve rod has the curved surface of one section radius gradual change.This structure makes valve rod as driving link, switch contact is as driven member, when rotary valve rod, because the curved surface of one section section radius gradual change is arranged, so just can make contact along with stretching out or indentation ground back and forth movement about the valve rod rotation, reach the effect of opening or closing switch
The curved surface of several sections radius gradual changes can be set on the tap valve rod, after can reducing gradually, the radius of each section curved surface increases gradually, or reduce gradually after increasing gradually, by at the valve rod curved surface keying that these structures can make tap control of pump under different flows being set in advance.
Switch and make it driven valve rod protective cover is set outward produces the unsafe hidden danger of electrical equipment with percolation-proof.
On the circuit control device pump working indicator lamp can be set; Water sucking mouth at water pump is equipped with bottom valve, between water pump and the water tap flap valve, clarifier etc. can be installed.Switch can adopt the contact microswitch, the work of microswitch control entire circuit, and microswitch is opened, and water pump supplies water.When microswitch cut out, relay electric-loss disconnected, and water pump quits work.
Above technical scheme is compared with prior art has following several advantage, the first, the utility model is opened and is closed by the direct contact-making switch control of pump of leading valve rod, even low discharge downforce and flowed fluctuation are frequent again, can not make the water pump frequent starting yet, thereby prolonged system application life, controlled also as safe as a house reliable.The second, the size adjustment of output is not subjected to the influence of this equipment volume, not only is suitable for low discharge and supplies water, and can realize easily that big flow supplies water yet, and has and the same advantage of low discharge water supply.Three, equipment such as clarifier can be installed easily in the water supply installation, concerning living in the relatively poor place of water quality, be the good equipment of water of making the life better; Four, entire equipment is simple in structure, and is easy for installation, and cost of production is low, is very suitable for uses such as family, peasant's sprinkling irrigation.The 5th, this device adopts opening and closing of an action while control of pump and water tap, reduces operation sequence, the convenient use.
In conjunction with the embodiments the utility model is described in further detail by accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
As seen in Figure 1, this water supply installation is made up of water pump 1, water tap 2, contact microswitch 3 and the circuit control system 4 that is connected with switch 3, switch 3 places on the support 13 on the pallet 5, pallet 5 tops have protective cover 6 with switch 3 and valve rod 7 be isolated from the outside out, the outer connectors 8 that are with servo-actuated of valve rod 7, connector can adopt various fixed to be connected with the water tap axle, as welding, fastening, the steady pin of screw etc.; Pallet 5 is fixedly mounted on the water tap 2 by nut, protective cover 6 inner chamber top center places have axle 10 to be inserted in the connector 8 and with its tight fit, valve rod 7 is a screw mandrel, have the conical surface 9 that one section radius increases from top to bottom gradually on its connector 8, the contact 11 on the microswitch 3 contacts with the surface of connector 8 all the time.
Inverse time rotates protective cover and drives the valve rod rotation by connector, and water tap is opened, and in the tap of fetching boiling water, connector moves up, and contact 11 closures that connector top-surface camber 9 promotes on the microswitches make relay 12 get electric adhesive, and water pump supplies water.During up time rotation protective cover, connector is to bottom offset, and the conical surface forces contact 11 to glide, and makes microswitch 3 disconnect, and the relay 12 on the circuit control system 4 is decontroled outage, and water pump 1 stops to supply water.Bottom valve 16 is installed in water sucking mouth at water pump 1, and flap valve 14, clarifier 15 etc. can be installed between water pump and the water tap.
The work of microswitch 3 control entire circuit systems, microswitch 3 is opened, and relay 12 gets electric adhesive, and water pump supplies water.In relay 12 adhesives, relay indicating light 17 display working conditions, when microswitch 3 cut out, relay 12 dead electricity disconnected, and water pump quits work.In the entire circuit control system, power supply indicator, earth leakage protective device, stable-pressure device etc. can be installed.
