Description
Technical field
The utility model relates to a kind of valving that automaticallyes switch, and the water resource heat pump free piston type well that is specially adapted to use in the water resource heat pump type traditional central air-conditioning system in the field of Refrigeration and Air-conditioning draws water, recharges automatic switchover.
Background technique
The water resource heat pump traditional central air-conditioning system is the green air conditioner system of a kind of energy-saving and environmental protection of wideling popularize of China recent years.And well recharges that to stop up be the key problem that water source heat pump air conditioning system will solve, and solution to this problem is Hui Yang (being that recharge well becomes pumped well).The method that realizes now well Hui Yang be at the well head place drinking-water pipe, recharge a switch butterfly valve respectively be set on the pipe.If realize Hui Yang, need under the operation worker in inspection-pit, back-water valve (BWV) to cut out, the valve that draws water is opened, return raise 15～20 minutes after, in inspection-pit, back-water valve (BWV) is opened down again, the valve that draws water cuts out, and recovers the function that well recharges.Well generally leaves more than the machine room 50m, and the inspection-pit well depth is about 2m, and action need is removed heavy well lid at every turn, in inspection-pit, just can finish down.And each recharging well returns and raises action need and will carry out once weekly, if recharge well is a lot, manually-operable work is very heavy.The method that the prior art head it off is commonly used is to replace Hand-operated butterfly valve with electric butterfly valve, though this method has solved heavy manual labor, also can exist increases a lot of engineering work load and engineering cost, and operation still needs defectives such as strange land manually-operable.
Summary of the invention
Goal of the invention of the present utility model provides a kind of simple in structure, and is easy to use, and cost is with low cost, and the water resource heat pump free piston type well that solves the automatic switchover problem of recharging, drawing water of well draws water, recharges the automatic switchover control valve unit.
The technological scheme that realizes goal of the invention is to solve like this: water resource heat pump free piston type well draws water, recharges the automatic switchover control valve unit, comprise a valve body, the upper end of valve body is provided with and recharges the recharge water mouth of pipe C that water pipe is connected, the lower end is provided with the water pump mouth of pipe B that is connected with water pump pipe, and the middle part is provided with the hose nozzle A that is connected with the system water pipe.Its improvements of the present utility model are also to be provided with a up and down free-piston at the inner chamber of valve body, and the two ends of described free-piston also are equipped with the O rubber seal.
The utility model compared with prior art, simple in structure, easy to use, cost is with low cost, thoroughly solved the automatic switchover problem of recharging, drawing water of well, and need not use additional power source, have at any time again simultaneously draw water reliably, recharge that function is switched arbitrarily, the stuck function of fine sand in the anti-sealing, the water resource heat pump free piston type well of having simplified the matched tube structure of well mouth greatly and having improved operating characteristics draws water, recharges the automatic switchover control valve unit.This device had both solved the complicated or baroque drawback of a job of the artificial or electronic switching of well, also solved switching valve because of containing the stuck problem of sand in the water, therefore the utility model is after using on the well, and pipe arrangement is succinct, has reliable operation, characteristics such as simple to operate.Good social and economic benefit are arranged.

Embodiment
Accompanying drawing is embodiment of the present utility model
Below in conjunction with accompanying drawing content of the present utility model is described further:
With reference to Fig. 1, shown in Figure 2, comprise a valve body 1, the upper end of valve body 1 is provided with and recharges the recharge water mouth of pipe C that water pipe is connected, the lower end is provided with the water pump mouth of pipe B that is connected with water pump pipe, the middle part is provided with another recharges the recharge water mouth of pipe A that water pipe is connected, it is characterized in that also being provided with a up and down free-piston 2 at the inner chamber of valve body 1, the two ends of described free-piston 2 also are equipped with O type rubber seal 3.Seal water pump mouth of pipe B when free-piston 2, valve body 1 inner chamber is promptly formed the recharge water system; Seal water pump mouth of pipe B when free-piston 2, valve body 1 inner chamber is promptly formed pumping system.
In sum, the intracavity diameter of valve body 1 is than the big 2～4mm of free-piston 2 diameters., under the effect of current, free-piston 2 can float by easy on and off in valve pocket.On the free-piston 2 two ends conical surfaces O type rubber seal 3 is installed.
When well recharges, free-piston 2 is under the effect of gravity, automatically fall on the valve seat of the diving pump line conical surface, the air pump inoperative owing at this moment dive under water, the bottom pressure of free-piston 2 is about atmospheric pressure, the down pressure that the recharge water that comes from system flow produces on free-piston 2 tops, and it and piston gravity produce the downward sealing load of valve together, the recharge water of system is just flow to by the A mouth and recharges a mouthful C, finishes with making system stability and recharges workflow.
If submersible pump is in operation, valve is to finish the automatic switchover of drawing water like this: free-piston 2 bottoms are in the throttling action in the gap of 1～2mm under the pump discharge pressure effect and between by free-piston 2 and valve body 1 inner chamber, in free-piston 2 bottoms, pressure reduction is formed at top, obtain pressure reduction upwards and make a concerted effort, the gravity that overcomes free-piston 2 moves upward.Because it is atmospheric pressure that mouthful pressure at C place is recharged in connection, the length of free-piston 2 approximates the diameter of valve body 1 interface A, piston is when moving upward to the A mouth and moving upward, forming stable upwards pressure reduction up and down at free-piston 2 makes a concerted effort, be pressed onto firmly on the conical surface valve seat that recharges pipe C up to free-piston 2, drawing water stably flows to the A mouth from the B mouth, finishes that well draws water or the workflow of Hui Yang.Because the gap of 1～2mm is arranged between free-piston 2 and the pump housing intracavity diameter, and free-piston 2 can be not stuck because of containing fine sand in drawing water, so automatic transfer valve has the stuck function of anti-fine sand.Be taper as lower valve base on the free-piston 2 of spool and the valve body 1, thus valve on move to or below on the valve seat time, the automatic guide effect is arranged, the not tight phenomenon of valve closing can not take place.The intracavity diameter of valve body 1 is than the big 2～4mm of free-piston 2 diameters or 2～3mm or 1～1.5mm.The height of valve body 1 inner chamber is 3.0～3.5 times of diameter of valve body interface A.In the operation of air conditioner process, its administrative staff only need operate pump switch or system's backwater switch, this device can be closed automatically and be recharged mouth of pipe C or water pump mouth of pipe B, fundamentally solved the automatic switchover problem of recharging, drawing water of well, and need not use additional power source, any switching of drawing water, recharging function is reliably arranged at any time simultaneously.
