Abstract

The present inventive fluid adjusting screw has an improved concentric precision with a screw hole that guides the screw thereby equalizing the ring-shaped gap formed between a tapered needle valve part and a measuring hole for improving and equalizing the precision in controlling fluid. The techniques of the invention is that a large diameter cylinder part 5 and a small diameter guide cylinder part 6 are formed concentrically from a male screw part 3 of the fluid adjusting screw P toward the tapered needle valve part 4. A female screw part 10, a large diameter guide hole 11, a small diameter guide hole 12, and a measuring hole 13 are bored concentrically in a fluid controller 1 inward from the outer side end. The male screw part 3 of the fluid adjusting screw P is attached to the female screw part 10, the large diameter guide cylinder part 5 is supported at the large diameter guide hole 11 with a guided length (A) and the small diameter guide cylinder part 6 is supported at the small diameter guide hole 12 with a guided length (B). Further, the tapered needle valve part 4 is inserted into the measuring hole 13.

536585 __ I 111 1 丨 丨 丨 One _ V. Description of the Invention (1) Technical Field The present invention relates to a fluid adjusting screw for a fluid provided in a fluid controller, wherein the adjusting screw of the fluid controller is adjusted. 2. Don't use fluids for vaporizers. BACKGROUND OF THE INVENTION For the vaporizers in the prior art, they will be described below, and the adjustment C screw is shown in Figure 2. Element number 1 is the vaporizer body, 2e :, Ran, main control Screw. The air passage, II, is omitted to constitute the vaporization: shell = suction element number P inside the vaporizer body is used to adjust the low-speed mixing ° popular other factors. The main control screw, the component number 30 of the fluid control screw provided by the main control screw is provided at the rear part of the π component: the main control screw is provided to rotate the main control screw ρ, and the threaded portion 'on the rear end face of the component number 31 is provided at The meaning is 之间 ° between the circumferential groove 30A, and the conical needle valve 31, as follows :: The conical needle valve part, the two ends of the external thread part are connected to the conical needle valve part 31, that is, the small diameter of f in the external thread part 30 The guide cylinder 32: the small-diameter guide cylinder 32 and ί are set to be smaller than the small-diameter _ X j? Small-port lithium connection part between the conical needle part 3], and the ⑽, the connection part 33, and the circle * the main control screw ,.卩 疋 Concentric-formed by the body. Yugang. The hoisting cymbal is manufactured by a lathe. Its material is

The outer end of the body 1 (upper in Fig. 2) is concentrically inward § and the inner screw part 40 for screwing into the outer thread part 30 (including the hole part at the bottom of the thread), the guide support is small = 3 2 Guide the small-diameter hole 41 and the cutting post 42. The metering hole for inserting the conical needle valve part 31: the upstream 42A of the metering hole 42 is mixed with the low speed, and the downstream 42B of the metering hole 42 is communicated with the low 7 inlet passage 43 and the above-mentioned low speed communicating with the suction passage 2; :: Path 44 is connected. To the mixed air flow inlet passage 43, a low-speed speed is provided. The chaos of the hunger passage is to use a low-speed material that is not shown in the figure, and to violate the control of the low-speed mixing low-speed air nozzle. The low-speed fuel is used and the above-mentioned main control screw 1 is used. The / L method 5 is placed in the carburetor. The main control screw P is inserted into the carburetor threaded portion 40 and inserted into the carburetor body 1 plate. The side end is screwed into the internal thread portion 40 through the opening, and this is g. The threaded portion 300 is supported by the small-diameter guide ^ = caliber guide cylinder 32 so as to move axially from the metering hole 42. A 'cone needle valve part 31 is also inserted into the element series 5 Tiger S! Is a spiral spring, ^ (as shown in the upper part of Figure 2), so that the main control screw P to push the dust to the _ side to eliminate the gap. . The threaded portion 30 and the internal thread portion 40. When the screwdriver is inserted into the groove 30A as above, for example, when the adjustment recess of the main control screw p formed in a clockwise direction is turned -__ ^, the main control screw P is inward 90127141.ptd Page 5 Fifth, the description of the invention (3) ί = :: the shape is between the conical needle valve part 31 and the measuring hole 42, Shang Shang ,, f, Dou Danxi, and so on, let the low-speed mixed gas enter the passage 4 3, 5 10 ns gap and low-speed mixed air flow exit path 44 enters the suction, and the passage of s I == the air volume is adjusted in the decreasing direction. When the main control path 2 is rounded: = turn, the main control screw exits outward. At this time, it is possible to know in the W cone needle valve part 3, so that the measurement gap between the low-speed mixed gas is increased. Large, the amount of mixed gas increases toward the low speed of the passage 44 into the suction passage 2. However, in actual use of the screw, it is necessary to ensure that the main screw 4 is used to communicate with the main body of the prior art. There are precise La and Ye Xia holes 42 (collectively referred to as screw adjustments even if it is difficult to adjust the above screw adjustments. 4 ″, metering holes 42) and the main “screw ^ screw ^ part 40 'small diameter guide When the main control screw ρ is assembled with the trowel, the holes have the correct concentricity, and the concentricity between them is exactly maintained; 4 screw: when the rod is adjusted in the hole, the positive rod cannot only guide the circle through the small diameter. The result is that the fluid adjusting screw is supported by the inability to maintain the correct upper-diameter guide hole 41. The valve section 31 and the measuring hole "are in particular, and in particular, the conical needle cannot supply the low-speed concrete normally and evenly?" The uniform annular gap 'is caused by this. In order to raise the above concentric SEIDO: 1 problem. It is considered that the cylinder 32 and the small-diameter guide hole 4m are increased to increase the small-diameter guide = 1 screw M length, ^ degrees, but this will increase the size of the fly / flyer. 536585

The fluid adjustment screw of the present invention is produced by the problem of θ. Its life is eliminated. In order to eliminate the above-mentioned problems in the prior art, the adjustment screw does not need to be increased to make a + AA ▲ tired # of the total length of the existing technology. With the concentric sound of its pilot holes, L can increase the fluid adjustment screw and ~ U. Degrees, U can control this. In order to achieve the above-mentioned purpose of the invention, the T / 夂 limb limb is equipped with a carburetor, which can adjust the fluid supply screw of ^, which is equipped with a circle at the end ;; == low-speed mixed gas volume, its characteristics Pattern part, from the thread part to the circle :, at the rear end, an external screw guide cylindrical part, a small-diameter guide cylindrical part 1 $ points are connected to set a large D-diameter lead, a large-diameter guide cylindrical part, small:; lead = make the above The externally threaded part 2 is formed concentrically and is controlled by the fluid; the internally threaded part that is concentrically arranged with the conical needle passes through, and penetrates and measures the hole from the outer end to adjust the above-mentioned fluid ζ diameter guide hole, In the small-diameter guide hole, the large-diameter guide round branch part = the internal thread part = the column part is supported by the small-diameter guide hole #, the cone needle valve part is equipped with two: = using the fluid adjustment screw of the present invention, 1 4 two Caliber guide hole support "], the caliber guide cylindrical part :: the main part of the guide SU is held, so that the fluid adjustment screw can be accurate, the caliber guide hole support part, the large-diameter guide hole, and the small-diameter guide; also, Placed in the internally threaded hole 'especially to make the cone Two exact valve portion;: screw within the coffin to be arranged in the metering orifice adjustment makes it possible to achieve adjustment of the bow uniformly mixed at low speed fluid such as radon, control.
