Description of the invention (1) The present invention is a kind of one-way pressurized supply The amount of lubricating oil is correctly distributed to the parts of the machine that need to be lubricated according to the predetermined proportion. The flow valve (fesistanceva 1 ve), also known as the throttle valve (thr 〇111 eva 1 ve). The conventional choke valve belonging to the present invention is mainly shown in, for example, FIGS. 9 and 10: a) a parallel pin-shaped choke stem 2a is inserted into a cylindrical hole formed in a passage member 1 such as a body; A cylindrical throttle valve; and b) a spiral throttle valve formed by forming an internal thread 3 in the hole of the same passage member 1 described above and fitting a shaft-shaped or cylindrical group-shaped throttle rod 2b into the hole . Printed by a Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs a) A straight shaft-shaped baffle stem 2a is inserted into a hole having a diameter of approximately 2 to 3 am that forms a cylindrical fluid passage in the body passage member 1, and the hole and the spacer (Spacer) An annular gap (0. 02οπή ~ 0.1mm) is formed between the outer peripheral surfaces to act as a throttle passage, so it is also called an annular throttle valve. According to such a choke valve, since the choke stalk 2 a is in a free state and is accommodated in the cylindrical hole i of the passage member 1, the above-mentioned annular throttle passage is formed around the choke stalk 2 a. Its characteristics. However, according to the characteristics of its structure, the upper stalk 2a is supposed to be held at the center portion where it is received, but it actually tends to be eccentric to one side of the inner surface of the hole. In this eccentric state, the flow rate of the fluid flowing through the non-annular gap around the choke rod 2a will be about 2.5 times larger than that of the completely non-eccentric annular gap. Therefore, its function and theory Contrary to this, it leads to the reliability of the distribution accuracy. In addition, the above 逑 b) is due to the embedment of the passage member 1 such as the body and the baffle rod 2b. The paper scale is applicable to the Chinese National Standard (CNS) A4 specification (2 丨 0X297). 401498 Λ7 'B7 V. Description of the invention (2) As a result, K does not cause the axis deviation of the above a), so there is no major error caused by the eccentric state. However, the positioning of the longitudinal position of the sleeve requires an additional means, and when compared with the ultra-micro flow setting and adjustment purposes, its composition tends to be longer or larger than the above a), so this kind of As for the convenience of the choke valve in practical application, there are still problems. According to the above, if the conventional choke valve belongs to the above-mentioned typical form, there is still room for improvement due to its constitution M and its function of adjusting the flow rate. The present invention relates to an economically cheapest choke valve distribution system, which can eliminate the disadvantages and shortcomings of the conventional technology, and provides a constant pressure as long as the pressure conditions of the fluid supply are not changed. The choke valve characterized by the ratio set by M to correctly distribute and supply the fluid to the mechanical part to be lubricated. The choke valve of the present invention can arbitrarily adjust the flow rate, and its adjustment range is large. Therefore, the present invention also provides an adjustable throttle valve. Conventional high-impedance choke valve is a choke valve with large resistance in the pipe. It is easy to change the flow rate and pressure loss due to the viscosity change caused by the temperature change of fluids such as oil. However, the present invention has a better restricting effect, so it can provide a novel choke valve that is less affected by pressure loss or viscosity changes. In order to achieve the above object, the present invention provides a throttle valve provided with a choke rod 2 for restricting the effective area of the hip passage, which is shown in the schematic diagrams of FIGS. 2 and 3 in the passage member 1 of the body and the like. The female thread 11 is formed on the inner peripheral surface and the male thread 12 is formed on the outer peripheral surface of the main part of the spoiler 2 so as to be screwable with the internal thread, and either one of the female thread 11 or the male thread 12 is -5- Paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm). 4U498 Λ7 'B7 printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs 5. The thread peak of the invention description (3) is cut off by a certain size plus M, so that It is characterized by the cut-out portion of the thread peak acting as the passage 3 of the fluid. The characteristics of this structure can be understood from the difference between the basic form of the triangular thread shown in Fig. 1 and the principle diagram of the present invention shown in Figs. Also, the conventional threaded throttle valve shown in Fig. 10 is an M thread groove as a flow blocking passage. In this regard, the present invention uses a space formed by partially cutting off a K thread peak as a flow blocking passage. As described above, when a part of the thread peak is cut off to form a flow blocking path, it can be seen from the differences between FIGS. 2, 3 and 10 that the present invention can set the effective cross-sectional area of the throttling path 3 more than the conventional spiral throttling structure. small. That is, for example, when the thread peak of a triangular thread is cut along the effective diameter of the thread (refer to the line in FIG. 1A), it has a favorable point that can set the flow rate to about 1/4 compared with the conventional structure (Figure 1G). . Therefore, according to the present invention, a large-impedance impedance function can be obtained, thereby providing a throttle valve with very little flow. The type of the thread of the upper structure of the present invention using K is not particularly limited, that is, for example, a triangular thread or a mesa thread may be provided as long as the female thread 11 and the male thread 12 can provide a fitting state between the inclined surfaces of the thread peaks. Therefore, with the exception of the angle-shaped thread K, which does not have a bevel, the thread peak is easy to process in the production process, and the manufactured threads can be used. Also, as shown in (a) and (b) of FIG. 3, if the spoiler 2 used is engraved with a contour of a male thread 12 whose thread peak is cut off, or a female thread 11 is engraved The contour of the inner periphery of the hole is formed as a push-out shape. When the two threads are screwed with each other and shifted in the length direction, the effective cross-sectional area of passage 3 is changed due to the effect of different parts of the height of the thread peak. As a result, the cross-sectional area changes. Change the opening of the throttling path. -6- This paper size is in accordance with Chinese National Standard (CNS) A4 (210X297 mm) (Please read the notes on the back to write this page-Binding and ordering printed by the Central Consumers Bureau of the Ministry of Economic Affairs, Consumer Cooperatives 401498 A7 'B7 ____ _V. Description of the Invention (4) That is, as shown in FIG. 3 (b), when the passage member 1 formed with the above-mentioned female thread 11 and the spoiler 2 with the male thread 12 and the push-out formed with each other, When the axis (length) is shifted, the effective part of the passage 3, that is, the cross-sectional area of the passage side, can be changed. With this structure, the male thread 12 and the female thread 11 are different from each other in the area of the passage 3. By screwing each other, the throttle opening can be set to a minimum, and at the same time, if the thread is moved to the zero (0) state, the flow rate adjustment can be set to the maximum amount. The above function is as shown in Figure 3 (b ) Is implemented in the form shown, that is, when the fluid flows from the higher side of the thread peak formed to the lower side of the thread peak formed by cutting, the minimum of the above-mentioned path 3 formed by the fitting of the female thread 11 and the male thread 12 Cross-sectional area (the mouth of the thread on the inflow side) The throttle opening degree can be obtained as the set flow rate. In addition, this function can realize a wider range of flow adjustment. In addition, when implemented according to the principle of Figure 3 (b), as the fluid enters the flow direction, On the downstream side, the resistance in the tube decreases, so the flow of the fluid can have a more restrictive effect. The throttling effect of the upper part is compared with the general high-impedance throttling of the blocked flow, because it is due to the flow of the fluid to the passage. It is obtained by the large cross-section side flow of 3. Therefore, compared with the conventional spiral throttle valve, a choke valve with less pressure loss can be provided at the same set flow rate. In addition, in the present invention, if the When the cross-section of the passage 3 is used to adjust the opening of the throttle passage, the length of the thread portion on the uncut side of the thread peak in the female thread 11 or the male thread 12 can be configured to be extremely short.
