Description
Technical field
The present invention relates to heat-exchange system electromagnetic valve, be specifically related to a kind of three-way magnetic valve switching refrigerant flow path in air-conditioning conditioner.
Background technology
Switch over it is known that cold and heat air adjusting means typically requires the runner to cold-producing medium, on valve seat, slide to open or close corresponding valve port by slide valve and realize.Prior art use mostly three-way magnetic valve meet above-mentioned functions needs, and by controlling its coil control system of switching on or off electricity cold-producing medium switching between two runners.Specifically refer to Fig. 1, Fig. 2, respectively illustrate a kind of three-way magnetic valve overall structure schematic diagram two kinds of duties.
As shown in Figure 1, first adapter 2' is connected with the one side of the valve body 6' of electromagnetic valve, opposite side at valve body 6' embeds and installs and fixes the valve seat 12' being formed with two valve ports 14a', 14b' being made up of circular through hole, and the second adapter 3', the 3rd adapter 4' are connected communicatively with above-mentioned valve port 14a', 14b' respectively, thus, the first adapter 2' is become and state that the second adapter 3', the 3rd adapter 4' connect by means of valve body 6'.
Being configured with slide block 10' on the valve seat 12a' of valve seat 12', the state that this slide block 10' contacts with sealing surface 10a' and valve seat 12a' is arranged on valve seat 12a', makes this smooth sealing surface 10a' and valve seat 12a' sliding contact.Connecting rod 16' extended at direction of principal axis is connected with slide block 10', and, abut, in the face of the opposition side of the sealing surface 10a' of slide block 10', the leaf spring 24' that oriented sealing surface 10a' side is afterburning.
When solenoid is not powered on, plunger 18' is because moving downward under the effect of the elastic force of helical spring 20', as it is shown in figure 1, so that the slide block 10' being connected with plunger 18' by means of connecting rod 16' also declines, its sealing surface 10a' seals the valve port 14a' of lower side.At this moment, strongly being pushed to valve seat 12a' due to slide valve 10' because of the elastic force of above-mentioned leaf spring 24' and the cold-producing medium flowed into from the first adapter 2', therefore valve port 14a' becomes the state being reliably sealed.Therefore, the cold-producing medium flowed in valve body 6' from the first adapter 2' is flowed out to the 3rd adapter 4' by valve port 14b'.
On the other hand, when solenoid is energized, attractor 22' magnetic suck plunger 18', plunger 18' is made to overcome the elastic force of helical spring 20' to rise, as in figure 2 it is shown, the slide block 10' being connected with plunger 18' by means of connecting rod 16' also rises, its sealing surface 10a' seal the valve port 14b' of upper side.At this moment, strongly being pushed to valve seat 12a' due to slide block 10' because of the elastic force of above-mentioned leaf spring 24' and the cold-producing medium flowed into from the first adapter 2', therefore valve port 14b' becomes the state being reliably sealed.Therefore, the cold-producing medium flowed in valve body 6' from the first adapter 2' is flowed out to the second adapter 3' by valve port 14a'.
But, the electromagnetic valve of this structure, it is that two valve ports 14a', the 14b' arranged the same side up and down by connecting rod band movable slider 10' carry out opening and closing operations, therefore two valve ports 14a', 14b' must have a certain distance adding man-hour, and in order to ensure that slide block 10 can block one of them valve port in running completely, then the stroke of slide block 10' have to be larger than the diameter of valve port 14a' or 14b', i.e. L ＞ (L1+L2)/2, wherein L is the stroke of slide block 10', L1 is the diameter of valve port 14a', and L2 is the diameter of valve port 14b'.And owing to slide block 10' is driven by plunger 18', then the stroke of slide block 10' is the operating range between plunger 18' and attractor 22', this operating range is the biggest, it is necessarily required to bigger electromagnetic force drive, so, in order to meet the performance requirement of electromagnetic valve, it is necessary to strengthen the power of coil to improve electromagnetic force.
Therefore, how to design one and need not high-power coil, it is possible to improve electromagnetic force, and reduce the electromagnetic valve of the actuating length of plunger, it is achieved the reliable switching to air-conditioning system pipeline, just become the technical problem that those skilled in the art are urgently to be resolved hurrily.

Detailed description of the invention
For making those skilled in the art be more fully understood that the present invention, below in conjunction with Figure of description, embodiments of the present invention are described in detail.
First embodiment:
Refer to Fig. 3, Fig. 3 is first embodiment of the invention structural representation.
As shown in Figure 3, Figure 4, the three-way magnetic valve that the present invention provides mainly is assembled by valve body 2 and coil 1, valve body 2 includes the valve body 21 in general cylindrical shape structure, it is internally formed valve pocket 22, outer peripheral face at valve body 21 connects the first discharge connection 4 and the second discharge connection 5 and entrance sleeve 3, in the present embodiment, the central axis S1 of the first discharge connection 4 and central axis S2 of the second discharge connection 5 is located along the same line.In order to the first discharge connection 4 and the second discharge connection 5 are connected on valve body 21, first periphery at valve body 21 can process two holes being oppositely arranged, then by the way of welding, the first valve seat 41 and the second valve seat 42 are separately fixed on two holes, and the first discharge connection 4 and the second discharge connection 5 are separately fixed on the first valve seat 41 and the second valve seat 42.The bearing of trend of entrance sleeve 3 is set to vertical with the bearing of trend of the first discharge connection 4.
First valve seat 41 and the second valve seat 42 can take identical structure, are therefore only described as a example by the first valve seat 41 below, and those skilled in the art it will be seen that, the description to the first valve seat 41 is equally applicable to the second valve seat 42 below.
First valve seat 41 is substantially in cylinder, as it is shown in figure 5, offer the first pilot hole 411 and the first-class through hole 412 of path in big footpath inside it successively.Wherein, the first pilot hole 411 is for coordinating with the first discharge connection 4 and sealing fixing；First-class through hole 412 is then for the circulation of fluid, and is blocked by slide block 6 or turned on.
The end face (end of first-class through hole 412) of the first valve seat 41 is set to plane, thus form primary sealing area 413, owing to the second valve seat 42 has the second pilot hole 421 and second through hole 422 equally, and second the end face of valve seat 42 be also configured as plane, i.e. secondary sealing area 423, so, primary sealing area 413 and secondary sealing area 423 just constitute the plane being parallel to each other a pair, and the opening of first-class through hole 412 and second through hole 422 then lays respectively on primary sealing area 413 and secondary sealing area 423.
As shown in Figure 6, valve body 2 also includes that sleeve pipe 23, sleeve pipe 23 are set on valve body 21, are generally fixed by modes such as welding.The other end of sleeve pipe 23 then seals and is fixed with end socket 25, so, valve body 21 and sleeve pipe 23, an airtight cavity volume is just constituted between end socket 25, in this cavity volume, it is provided with core iron 24, core iron 24 is cylindrical, (on the basis of accompanying drawing 6) can be slided up and down in sleeve pipe 23, simultaneously, core iron 24 offers cavity, spring 26 it is provided with in cavity, spring 26 is resisted against between core iron 24 and end socket 25, when solenoid is cold, elastic force effect due to spring 26, gap is there is between core iron 24 and end socket 25, when the solenoid is activated, produce magnetic field, make core iron 24 overcome on the elastic force of spring 26 to move, with end socket 25 adhesive, as shown in Figure 6.
As shown in Figure 8, the bottom of core iron 24 is provided with connection sheet 242, big to plate-shaped, and is provided with installing hole 241, is used for installing slide block 6.
Refer to the slide block schematic appearance that Fig. 7, Fig. 7 are first embodiment of the invention.Slide block 6 is the most cylindrical, there is outer edge surface 65, the shape of outer edge surface 65 adapts with the shape of the installing hole 241 connected on sheet 242 of above-mentioned core iron, so, just slide block 6 can be connected with core iron 24, in the present embodiment, the outer edge surface 65 of slide block 6 is connected for non-close-fitting with installing hole 241, i.e. core iron 24 and slide block 6 along the axis direction of installing hole 241, i.e. core iron 24 in the radial direction can the most slidably.
Two end faces of slide block 6 are respectively arranged with the first sealing 61 and the second sealing 62, wherein, first sealing 61 is for blocking the first-class through hole 412 on primary sealing area 413, and the second sealing 62 is for blocking the second through hole 422 on secondary sealing area 423.In the direction, longitudinal section along slide block 6, in the first sealing 61 and the second sealing 62 be generally aligned in the same plane, and stagger a certain distance along the direction of motion of slide block 6.So, owing to first-class through hole 412 and second through hole 422 are coaxially disposed, therefore, when first-class through hole 412 is blocked by the first sealing 61, stagger a certain distance, i.e. second through hole 422 of second sealing 62 and second through hole 422 is in the conduction state.
Side at the first sealing 61 place of slide block, it is additionally provided with support rim 611, the number of support rim can be set as required, it is 4 in the present embodiment, the height of support rim 611 and the height of the first sealing 61 are roughly equal, so, support rim 611 and the first sealing 61 just constitute the 3rd sealing surface 63 of slide block, the relatively low groove in relative position 612 it is the formation of between support rim 611 with the first sealing 61, when the first sealing 61 fits with primary sealing area 413, and when blocking first-class through hole 412, support rim 611 fits with primary sealing area 413 equally, groove 612 then constitutes the circulation passage of fluid.
Equally, owing to slide block is symmetrical structure, therefore in the side at the second sealing 62 place of slide block, it is again provided with support rim 621 and groove 622, this support rim 621 and the second sealing 62 then constitute the 4th sealing surface 64 (not shown) of slide block, and this is no longer going to repeat them.
3rd sealing surface 63 and the 4th sealing surface 64 are also in parastate, and distance between the two is less than the distance between primary sealing area 413 and secondary sealing area 423, so, slide block 6 just can have certain slide displacement between primary sealing area 413 and secondary sealing area 423, thus alternatively blocks the opening being arranged on primary sealing area 413 or secondary sealing area 423.
When solenoid 1 is energized, core iron 24 is by electromagnetic force, with end socket 25 adhesive, core iron 24 band movable slider 6 moves upward, and the second sealing 62 of slide block 6 is directed at the second through hole 412 of the second valve seat 42, simultaneously because be non-close-fitting structure between the outer edge surface 65 of slide block 6 and the connecting hole 241 of core iron 24, therefore, slide block 6 can be extruded to the right under the effect of fluid pressure, make slide block 6 be fitted in firmly on secondary sealing area 423, thus second through hole 422 is blocked.Now, fluid enters from entrance sleeve 3, and the left groove 612 along slide block 6 flows out from the first discharge connection 4.
In the present embodiment, when slide block 6 rises to extreme position, first-class through hole 412 is blocked by the first sealing 61, when slide block 6 drops to extreme position, second through hole 422 is blocked by the second envelope portion 62, therefore, it is positioned at the first sealing 61 and second sealing 62 distance on longitudinal cross-section of slide block 6 both sides, is the slide block 6 movement travel in whole work process.
In order to ensure the effectiveness that slide block 6 blocks, in the case of first-class through hole 412 and second through hole 422 have same apertures, only the movement travel of slide block 6 need to be equal to or is slightly less than first-class through hole 412 or the diameter of the second circulation 422.When the movement travel of slide block 6 is slightly less than the diameter of first-class through hole 412 or second through hole 422, although when the first sealing 62 blocks second through hole 422, first sealing 61 can block a part of first-class through hole 412 simultaneously, but, existence due to groove 612, fluid still can flow out along groove 612 from the first discharge connection 4.
And in the case of first-class through hole 412 is different with the aperture of second through hole 422, the most only need to ensure the opening diameter that the movement travel of slide block 6 is bigger equal to or slightly less than in two openings.The movement travel of slide block 6 more than the diameter of second through hole 422, is then equal to or is slightly less than the diameter of first-class through hole 412 by the diameter of first-class through hole 412；Otherwise, if the diameter of second through hole 422 is more than the diameter of first-class through hole 412, then the movement travel of slide block 6 is equal to or is slightly less than the diameter of second through hole 422.
It should be noted that, " being slightly less than " of the present invention refers to the movement travel of slide block to be made appropriate reduction, it will be appreciated by those skilled in the art that, error within the allowed band that above-mentioned can be in right amount is caused because of machining, it is also possible to be the setting having a mind to reduce electromagnetic force further make.
In reality is processed, the first sealing 61 and the second sealing 62 distance being staggered in the vertical can be designed, then by mode molding such as injections as required.Obviously, this structure is in terms of existing technologies, the movement travel of slide block 6 can greatly reduce, owing to core iron 24 moves with slide block 6 simultaneously, therefore the stroke of core iron reduces the most accordingly, so, drive the electromagnetic force of core iron 24 motion to reduce, low power coil therefore can be used to can be realized as.
