Embodiment
Relevant embodiment of the present invention, conjunction with figs. describes as follows.
Fig. 1 is the structural representation of the present invention's the 1st mode of execution.This mode of execution is to be useful in the outdoor system of split type air conditioner to be connected with pipeline between indoor heating system and to use Twoway valves.Fig. 1 is the outward appearance oblique drawing of Twoway valves, and Fig. 2 is the longitudinal section of the A-A face of its closed condition.
As Fig. 1 and shown in Figure 2, it is valve body 101 through forging and molding that Twoway valves 10 is to use aluminum alloy.This valve body 101 is cylindric, has the 1st path 10 2 and the 2nd path 10 3, the 1 path 10s 2 and the 3 mutual orthogonal settings of the 2nd path 10.And then the 1st path 10 2 is by constituting with the integrally formed joint 104 of valve body 101, simultaneously, described valve body 101, with for the fixed component 30 of fixing Twoway valves 10 through aluminum alloy forged and integrally formed.On this joint 104, for example can soldering be welded with the outdoor system pipeline with managing (not having diagram).The connection mouth 105 that the 2nd path 10 3 constitutes towards the indoor side system, the point of its outer surface is provided with screw section 106, is connected and fixed on this screw section 106 with the indoor side system pipeline to be connected nut engaged with pipe (not having diagram).And, on the operative end 111 of the outer surface of valve body 101, be provided with screw section 108, during not operation, as shown in Figure 2, screwing togather and covering 40.And, described joint 104 as shown in Figure 2,104 ends are formed with length A from valve body 101 to joint, this length A is ideal between 3mm-50mm.Relative therewith, when A=3mm is following, in the process of welding with pipe, the intensity of valve body there is considerable influence, when A=50mm is above, be difficult for forging processing.
In addition, as Fig. 1 and joint 104 shown in Figure 2, connection is arranged on the base portion 101 ' of valve body 101, on the base portion 101 ' of described valve body 101, is provided with fixed component 30.Its fixed component 30 is the setting of radiation direction from the outer surface of described base portion 101 ', promptly forms described fixed component 30 from the outer surface radially outward of base portion 101 ' is outstanding.
In object lesson as depicted in figs. 1 and 2, described fixed component 30 can be greater than the outstanding length of other parts in the outstanding length of the relative both sides of the outer surface of described base portion radially outward, and this two long radially projection forms the joint 31 of fixed component.Like this, this fixed component 30 is the handguard shape of sword, for omiting rectangular.On this two joint 31, promptly on rectangular two tips of fixed component 30, be formed with attachment hole 32 and 32 '.Insert construction bolt in this attachment hole 32 and 32 ', the mounting plate when making fixed component 30 and being installed in outdoor system (not having diagram) is connected, thereby Twoway valves 10 is fixed on the outdoor system mounting plate.
In addition, the inside of valve body 101 disposes valve rod 20 as shown in Figure 2, and valve rod is the same with Twoway valves before described, by manually-operable, and at the internal motion of valve body 101, thereby described the 1st path 10 2 of switch and the 2nd path 10 3.Promptly, as shown in Figure 2, the inside of valve body 101 is provided with: screw section 107 that is meshed with the screw section 22 of valve rod 20 and the valve seat 109 that is provided with between described the 1st path 10 2 and the 2nd path 10 3, the valve head 21 of described valve rod 20 is seated in this valve seat 109.
And then the inside of described valve body 101 is provided with by hole processing, and its inner described screw section 107 that forms is provided with by screw thread processing.Described valve seat 109 forms by the machining of regulation, and valve seat 109 is formed on the depths of 101 inside, and is arranged between described the 1st path 10 2 and the 2nd path 10 3.
And, between valve rod 20 and valve body 101, dispose sealed member 23, valve rod 20 utilizes the manually-operable of sending from valve body 101 operative end 111, and the operating end head 24 of actuate valve stem 20, make the motion of valve rod 20 by its operation in valve body 101 inside, and switch the 1st path 10 2 and the 2nd path 10 3.In addition, when described valve rod 20 moves to stop ring 110 positions of valve body 101 inside, stop to drive.
As mentioned above, by present embodiment Twoway valves 10 as can be known, because valve body 101 is through aluminum alloy forged formation, so joint and the valve body 101 with fixed component shape can be made easily.
In addition, because the valve body 101 of above-mentioned shape can form easily, so, improved the work efficiency of valve body 101.
It then is the present invention's the 2nd mode of execution explanation.Fig. 3 and shown in Figure 4 be the three-way valve of the valve for jointing pipeline in the embodiment of the present invention 2, Fig. 3 is the outward appearance oblique drawing of its three-way valve, Fig. 4 is the longitudinal section of its closed condition B-B face.So, Fig. 3 and mode of execution shown in Figure 4 are with the mode of execution of Fig. 1 and Twoway valves shown in Figure 2, difference is that the mode of execution of Fig. 1 and Fig. 2 does not possess valve inside, and other are all identical, the same part that constitutes is saved explanation with same symbolic representation.
Three-way valve 50 as shown in Figure 3, use the aluminum alloy as metal to form valve body 501 through forging.This valve body 501 is cylindric, has the 1st path 10 2 and the 2nd path 10 3, the 1 path 10s 2 and the 3 mutual orthogonal settings of the 2nd path 10.And then the 1st path 10 2 is made of the joint 104 that forms one with valve body 501.In addition, this joint 104 is identical with the 1st embodiment, connects to be arranged on the base portion 501 ' of valve body 501, has fixed component 30 on the outer surface of base portion 501 ', and its effect is the three-way valve 50 that is used for fixing through aluminum alloy forged formation one.Further, valve body 501 has the 3rd passage 502 that disposes with described the 2nd path 10 3 subtends, is slightly T word shape on valve body 501.The inside of the 3rd passage 502 is provided with as shown in Figure 4 in order to fill the valve inside 60 (as shown in Figure 4) of medium.And, be formed with screw section 503 on described the 3rd passage 502, work as non-working condition, when not filling medium, be furnished with nut 70 on the end of its passage 502.
Relevant three-way valve 50, the same with the 1st mode of execution, by aluminum alloy forged making, as shown in Figure 4, almost have the internal structure same with Twoway valves.That is, the 1st path 10 2 is arranged on the joint 104 on the base portion 501 ' of valve body 501 and constitutes by connection; The 2nd path 10 3 constitutes connection mouth 105; The 1st path 10 2 and the 2nd path 10 3, switch is carried out in the motion of the valve rod 20 by being configured in valve body 501 inside.And, the valve head 21 of described valve rod 20, and be arranged on valve seat 109 sealings of 3 of the 1st path 10 2 and the 2nd path 10s.
Further, three-way valve 50 has the fixed component 30 that is integrally formed on valve body 501 base portions 501 ', and this fixed component 30 is identical with the formation of Twoway valves, is used for fixing three-way valve 50.
And the filled utensil that the medium utilization is certain is filled in the 3rd passage 502 that is arranged on the described three-way valve of having fixed 50 by valve inside 60.
As described above, the valve body 501 in the three-way valve 50, because through aluminum alloy forged formation, so, even have the 3rd passage shown in Figure 1, and the shape of fixed component, make also very simply, and can reduce manufacture cost.
The above only is the schematic embodiment of the present invention, is not in order to limit scope of the present invention.Any those skilled in the art, equivalent variations and the modification done under the prerequisite that does not break away from design of the present invention and principle all should belong to the scope of protection of the invention.
