【0042】
Next just stream transfers device 40 to describe.Fig. 7 is that profile, the Fig. 8 after stream accent device amplifies among Fig. 2 is that stream transfers profile, Fig. 9 after device decomposes to illustrate the oblique view that concerns and amplify between flow adjustment valve and the empty cave.And also the relation of empty cave and body is illustrated out with cylindrical body among this figure.Figure 10 is the key diagram that stream is transferred device.
Flow adjustment valve 41 constitutes by having the size that can be inserted into 18 li in empty cave and the rounded cylindrical body 42 of length, and is made by synthetic resin.
【0043】
This cylindrical body 42 is shown in Fig. 8 (c): an end is made as adjusts valve 43, and the other end is made as installs the installation portion 45 that stream is transferred nut 55 and stream tuning knob 57; In cylindrical body 42 inside, a part is cavity 42 0Because the part of cylindrical body 42 is made as the cavity, is under the made situation of resin in cylindrical body, just can further improve the dimensional accuracy of cylindrical body 42, the compactness between assurance and the empty cave 18.And axial about central portion of cylindrical body 42 has concavity groove 42 1, dress O shape circle 46 in this concavity groove.
Installation portion 45 is reduced after place, cylindrical body 42 ends is through 2 section differences, in the thick part 45 of diameter 1On adorning the stream that is used for fixing flow adjustment valve 41 and transferring nut 55; The part 45 that diameter is thin 2On adorning stream tuning knob 57.For make stream tuning knob 57 more easily pack into diameter thin 45 2In, generally adopt embedded assembling gimmick.
【0044】
Stream transfers the central portion of nut 55 diameter to be arranged than installation portion 45 1The opening 56 of slightly larger in diameter, its internal perisporium 55 1On be carved with female screw thread, with the annular projection 11 of body 11 2Male screw thread be screwed.
The central portion of stream tuning knob 57 is provided with the opening 58 that is used to insert flow adjustment valve 41, and its inwall combines the card jail with leading section.
【0045】
Adjust valve 43 as shown in behind the end of amplifying cylindrical body 42 among Fig. 9, near cylindrical body 42 ends, from the end 42 3Beginning is D, downcuts the outer wall of cylindrical body 42 vertically in the position of orthogonal mutually with long axis direction in distance length vertically.Like this, be that the external perisporium of rounded cylindrical place residual after excision forms owing to adjust valve 43, thereby the little flow adjustment of the pressure loss just become possibility.Periphery wall area size should be able to cover through hole 13 at least 3Opening 13 30Such as, excision is tubular end of body 24 down 3Aperture area 1/2nd so that 3/4ths part.And length D is set at 1.5 times of opening diameter and even longer.
【0046】
What Figure 10 showed is the folding situation of adjusting valve.
Flow adjustment valve 41 is inserted in the empty cave 18, like this, adjusts valve 43 and just clogs through hole 13 3Opening 13 30, carry out Flow-rate adjustment by rotating flow adjustment valve 41 again.What Figure 10 (a) represented is exactly to adjust valve 43 to clog through hole 13 30Situation.Under this kind state, adjust valve 43 closures and do not form stream.From this state, counter clockwise direction half-twist, opening 13 30Open approximately 1/4, the space of leaving forms stream [referring to Figure 10 (b)].By half-twist more counterclockwise, then opening 13 30Open approximately 1/2, aperture area becomes greatly then that fluid flows more.By the way, as shown in Figure 9, be D if establish the length of adjusting valve 43, opening 13 30Diameter W, adjust in the valve 43, adjust and lead to opening 13 30The part of flow be X, then general more options are used the such scope of D 〉=W 〉=X.
【0047】
As mentioned above, even when opening 13 30When being in full-gear, stream transfers the adjustment valve 43 of device 40 also can make opening 13 30Only reach 1/2 (X=1/2W).Like this, when forming stream, from through hole 13 when operation closing device 20 2Bore or the void area between valve body 30 and the ring spacer 24 in come out to flow to again opening 13 30Flow will reduce.That is to say, because do not supply with whole opening 13 30The fluid of aperture area degree, even opening is enlarged more than certain area, flow can not change yet; So opening 13 30Maximum can only reach 1/2, just can make the fine setting of flow become simple thus.But, to transfer the installation site of nut 55, move up and down flow adjustment valve 41 by changing stream, the aperture area that adjustment valve 43 can be adjusted just can appropriateness change; According to the opening 13 of flowing through 30Fluid flow, also can regulate stream and transfer the installation site of nut to use.
