Description
Technical field
The utility model relates to the air conditioner technical field, specifically, relates to a kind of valve body sealing device that is applied on the air conditioner.
Background technique
As everyone knows, stop valve is one of parts commonly used on the air conditioner, usually uses at outdoor unit, valve body has three ports, two port connecting tubes wherein, another port are realized the sealing of body cavity with O shape rubber seal, nut cap, prevent the leakage of refrigeration agent.At present, along with expanding economy and Global Temperature warm day by day, domestic air conditioning is more and more universal, and still, general air-conditioning fluorine will occur lacking and cause the bad phenomenon of freezing after using one or two years, must could recover refrigeration by the Refilling refrigerant.Cause the reason that air-conditioning leaks fluorine to be mostly that there is slowly leakage in air-conditioning, mainly occurs in the bell-mouthed joint of outdoor unit stop valve and connecting tube.Referring to Fig. 1, a kind of existing stop valve structure schematic diagram.Two ports of stop valve are connecting copper pipe 18, connecting tube 15 respectively, connecting tube horn mouth 151 directly is connected with taper joint 17, be tightened on by hexagon nut 14 on the valve port of valve body 19, if the connecting tube bend pipe occurs, trickle slit, joint then easily appears in the docking situation such as not in place, causes refrigerant to leak slowly.Then only be screwed on the valve port screw thread with nut cap 12 in the another port, because the machining accuracy of screw thread is not high, between the screw thread interlock not rigorous, equally easily cause refrigerant to leak slowly, gently then need irregularly to add refrigeration agent, heavy then need to change stop valve, but stop valve changed, just need first outdoor unit is pulled down, weld again, again vacuumize and inject a series of activities such as refrigeration agent, waste time and energy very much, and floor is higher, the outdoor unit dismounting is abnormally dangerous.Air conditioner coolant is generally R22 at present, coolant leakage can destroy atmospheric layer, destroys earth environment, and maintenance to fill the fluorine expense higher, bring the loss of money and greatly inconvenience to air conditioner user, therefore design and a kind ofly can prevent that valve body sealing device that air-conditioning leaks slowly highly significant.
The model utility content
The utility model provides a kind of sealability better valve body sealing device in order to overcome above-mentioned the deficiencies in the prior art.
The technical solution adopted in the utility model is: valve body sealing device, comprise valve body, valve pocket, the spool that in described valve pocket, slides, a port of described valve body is connected with being with bell-mouthed connecting tube, the port of described valve body is provided with taper joint, the horn mouth of described taper joint and described connecting tube is suitable, outside described horn mouth and described taper joint, be socketed with sealed cap, between described taper joint and described horn mouth, be provided with taper washer.
Described sealed cap is hexagon nut.
Described taper joint is provided with annular boss, and described taper washer is enclosed within on the described annular boss.
Be provided with O shape circle between the inwall of described spool and described valve pocket.
In the described valve body port of nut cap shutoff that is spirally connected near the valve body port of spool side, in described valve body port pad is set, between described pad and described nut cap, spring is set.
Described pad diameter is than the large 1～2mm of described valve body port external diameter.
Compared with prior art, the utlity model has following advantage:
1) seal arrangement of the existing air-conditioning Placement of the utility model improvement and valve body is set up taper washer between connecting tube horn mouth and taper joint, makes sealing between the two more reliable, and long-time use of prevention air-conditioning causes refrigerant to leak slowly.Taper joint design annular boss more is conducive to the installation of taper washer to be fixed.
2) under the sealed cap and the insecure situation of the seal with screwed joint between valve body of existing stop valve, by increasing at the stop valve nut cap spring and circular pad are installed, make pad with sealing valve port, effectively prevent the leakage of refrigerant.
3) high, the convenient maintenance and replacement of the utility model highly versatile, reliability.
Description of drawings
Fig. 1 is existing stop valve structure schematic diagram;
Fig. 2 is valve body sealing device structural representation of the present utility model;
Fig. 3 is that the connecting tube horn mouth of valve body sealing device shown in Figure 2 connects partial enlarged drawing.
Embodiment
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Referring to Fig. 2, Fig. 3, the valve body 29 of stop valve is provided with three ports, and left port is sealed with nut cap 22, right output port connecting copper pipe 28, and upper end-hole is connected with connecting tube 25.Valve pocket is " fall T " shape, in valve pocket, be provided with can horizontal slip spool 31, thereby make " fall T " shape valve pocket realize cut-off and connect two states.Between the inwall of spool and cut-off valve pocket, be provided with O shape circle 30.The end of the upper end-hole of valve body 29 is taper joints 27, and taper joint 27 is suitable with horn mouth 251 shapes of connecting tube 25, tightens sealing by hexagon nut 24.At annular boss 271 of excircle design of the taper joint 27 of stop valve, between the horn mouth 251 of connecting tube 25 and taper joint 27, the taper washer 26 that equates with taper joint 27 taperings is set, thus the sealing of raising stop valve.The effect of annular boss 271 is fixing taper washers 26, prevents that it from coming off.
When connecting tube 25 is installed, taper washer 26 is enclosed within taper joint 27 tops, the root of taper washer 26 overlapped annular boss 271, microcephaly's internal diameter of taper washer 26 is equal to or less than taper joint 27 top external diameters, taper washer 26 is to be formed by corrosion-resistant, resistant to elevated temperatures plastics or rubber manufacturing, and elasticity is better, after taper washer 26 packs into annular boss 271, be subjected to annular boss 271 support large deformation, thereby wrap annular boss 271 and do not come off easily.Then, the horn mouth 251 of connecting tube 25 is placed in outside the taper washer 26, fixes by hexagon nut 24 and the mutual interlock of valve body screw thread, make between connecting tube horn mouth 251 and the taper joint 27 be connected tightr.Taper washer 26 has certain ductility, when connecting tube is installed, even exist connecting tube to be connected the problems such as skew with joint, can not cause the slit occurring between horn mouth 251 and the taper joint 27 yet, simultaneously, also avoided the phenomenon of when hexagon nut 24 is installed, being out of shape because of the excessive horn mouth that causes 251 of exerting oneself.As a kind of improvement, on taper washer 26, also can design an annular tongue, the annular boss 271 of the shape of annular tongue and position and taper joint 27 is adaptive.
The left port of valve body 29 is with nut cap 22 sealings, left port at valve body 29 arranges circular pad 23 shutoff left port, and at nut cap 22 and 23 on pad spring 21 is set, the diameter of pad 23 is slightly than the large 1～2mm of left port external diameter of valve body 29, pad can cover left port fully after guaranteeing to install, and prevents secondary refrigerant leakage.When nut cap after the outside thread of valve body left port is combined, along with tightening of nut cap, spring 21 is tightly pushed down the valve body left port with pad 23, effectively prevents the leakage of refrigerant in the valve body.
