Description

針閥裝置 Needle valve device

本創作係有關一種針閥裝置，尤指一種可精確控制流量，及可提高針閥移動之準確性之準確性等之針閥裝置。 This creation relates to a needle valve device, especially a needle valve device that can precisely control the flow and improve the accuracy of the movement of the needle valve.

參閱第7圖，公知之針閥裝置，其結構可簡化為：一流道組件81，係具有一進水通道811及一排水通道812。 Referring to FIG. 7 , the structure of the conventional needle valve device can be simplified as follows: a flow channel assembly 81 has a water inlet channel 811 and a drain channel 812 .

一環形座82，係設於該流道組件81上。 An annular seat 82 is mounted on the flow channel assembly 81 .

一控制部83，係設一圓錐狀伸縮桿831，並可控制該圓錐狀伸縮桿831對應該環形座82前伸或是後縮。當該圓錐狀伸縮桿831前伸時係可完全堵住該環形座82(如第8A及第9A圖所示)。並當該圓錐狀伸縮桿831後縮時係可完全退離該環形座82(如第8C及第9C圖所示)。 A control part 83 is provided with a conical telescopic rod 831 , and can control the conical telescopic rod 831 to extend or retract correspondingly to the annular seat 82 . When the conical telescopic rod 831 extends forward, it can completely block the annular seat 82 (as shown in Figs. 8A and 9A). And when the conical telescopic rod 831 is retracted, it can completely withdraw from the annular seat 82 (as shown in Figs. 8C and 9C).

配合參閱第10圖之第二曲線L2，假設該環形座82之孔徑為10mm；而因該圓錐狀伸縮桿831之橫斷截面積為圓錐形而非直桿形，故，對應於該環形座82之不同位置時，其間產生之流通截面積也不同(所以第二曲線L2呈弧線，而非直線)，舉例說明如下： Referring to the second curve L2 in Fig. 10, it is assumed that the diameter of the annular seat 82 is 10 mm; and since the cross-sectional area of the conical telescopic rod 831 is conical rather than straight rod, it corresponds to the annular seat 831. At different positions of 82, the flow cross-sectional area generated between them is also different (so the second curve L2 is an arc rather than a straight line). An example is as follows:

[a]全閉時：如第8A及第9A圖所示，當該圓錐狀伸縮桿831前伸至完全堵住該環形座82時，則其間之流通截面積=0。 [a] When fully closed: As shown in Figures 8A and 9A, when the conical telescopic rod 831 extends forward to completely block the annular seat 82, the flow cross-sectional area between them = 0.

[b]半開半閉時：如第8B及第9B圖所示，當該圓錐狀伸縮桿831對應該環形座82而後縮(此為全開的一半)一第一長度H1時，則其間之流通截面積=π(102-52)/4=58.9mm2。 [b] Half-open and half-closed: As shown in Figures 8B and 9B, when the conical telescopic rod 831 corresponds to the annular seat 82 and is retracted (this is half of the full opening) by a first length H1, the circulation therebetween Cross-sectional area=π(10 2 -5 2 )/4=58.9mm 2 .

[c]全開時：參閱第8C圖，當該圓錐狀伸縮桿831對應該環形座82再後縮至一第二長度H2(大於該第一長度H1)時，其間之流通截面積大約為=π(102)/4=78.5mm2(如第9C圖所示)。 [c] When fully opened: Referring to Figure 8C, when the conical telescopic rod 831 is retracted to a second length H2 (greater than the first length H1) corresponding to the annular seat 82, the flow cross-sectional area therebetween is approximately = π(10 2 )/4=78.5mm 2 (as shown in Figure 9C).

進一步，由第10圖之該第二曲線L2可發現，當該圓錐狀伸縮桿831在半開半閉時，雖然該第一長度H1等於該第二長度H2之一半，但是，該圓錐狀伸縮桿831對應該環形座82之間的流通截面積並非全開時之一半(應為39.25，實際上是58.9，大幅多於39.25)。也就是說，即使該控制部83可控制該圓錐狀伸縮桿831穩定的對應該環形座82相對移動，但其流通截面積並非呈現線性遞增(如第10圖之第二曲線L2所示，呈弧線遞增)，因此，若要精確的控制公知針閥裝置之流量，並無法以該圓錐狀伸縮桿831之移動量來進行等比例的推估。 Further, it can be found from the second curve L2 in FIG. 10 that when the conical telescopic rod 831 is half-open and half-closed, although the first length H1 is equal to half of the second length H2, the conical telescopic rod 831 corresponds to a half of the flow cross-sectional area between the annular seats 82 when it is not fully open (it should be 39.25, but it is actually 58.9, which is much more than 39.25). That is to say, even though the control part 83 can control the conical telescopic rod 831 to move relatively relative to the annular seat 82 stably, its flow cross-sectional area does not show a linear increase (as shown by the second curve L2 in FIG. The arc increases), therefore, in order to accurately control the flow rate of the conventional needle valve device, it is impossible to estimate proportionally with the movement amount of the conical telescopic rod 831 .

而許多欲以針閥裝置達到控制流量的設計，即因傳統針閥裝置係設置圓錐狀伸縮桿，進而無法以該圓錐狀伸縮桿之移動量來等比例的精確控制流量，造成業者很大的困擾。 However, in many designs that want to use needle valve devices to control the flow, that is, because the traditional needle valve device is equipped with a conical telescopic rod, it is impossible to accurately control the flow in proportion to the movement of the conical telescopic rod, resulting in a large number of operators. troubled.

有鑑於此，必須研發出可解決上述習用缺點之技術。 In view of this, it is necessary to develop a technology that can solve the above-mentioned conventional shortcomings.

本創作之目的，在於提供一種針閥裝置，其具有可精確控制流量，及可提高針閥移動之準確性等等優點。特別是，本創作所欲解決之問題係在於公知針閥裝置無法以圓錐狀伸縮桿之移動量，精確控制流量等問題。 The purpose of the present invention is to provide a needle valve device, which has the advantages of accurately controlling the flow and improving the accuracy of the needle valve movement.

本創作係為一種針閥裝置，參閱第1、第2、第3及第4A圖，其係包括：一流道組件10，係具有一進水通道11及一排水通道12。 The present invention is a needle valve device, please refer to Figures 1, 2, 3 and 4A, which includes: a flow channel assembly 10 having a water inlet channel 11 and a drain channel 12 .

一環形座20，係設於該流道組件10內，並介於該進水通道11與該排水通道12之間。 An annular seat 20 is disposed in the flow channel assembly 10 and is interposed between the water inlet channel 11 and the drainage channel 12 .

一針閥組件30，係設於該流道組件10上。該針閥組件30係具有一導引座31、一活動座32及一針閥33；該導引座31係插設於該流道組件10，並水密壓制於該環形座20上(如第4A圖所示)，該導引座31係具有一內螺紋部311及一內容室312，該內容室312係連通該進水通道11及該排水通道12。該活動座32係設於該內容室312；且該活動座32係具有一外螺紋部321、一第一端322及一第二端323；該外螺紋部321係介於該第一端322與該第二端323之間，並供該活動座32囓合於該內螺紋部311；該針閥33係設於該第一端322，且該針閥33係具有一圓柱狀殼體331、一導引空間332及至少一縱向剖溝333；該導引空間332係位於該圓柱狀殼體331內；該縱向剖溝333係用以連通該內容室312與該導引空間332，且該縱向剖溝333係具有一等寬之剖溝寬度d(如第6B圖所示)。 A needle valve assembly 30 is arranged on the flow channel assembly 10 . The needle valve assembly 30 has a guide seat 31 , a movable seat 32 and a needle valve 33 ; the guide seat 31 is inserted into the flow channel assembly 10 and is watertightly pressed on the annular seat 20 (as shown in the 4A ), the guide base 31 has an inner thread portion 311 and an inner chamber 312 , and the inner chamber 312 communicates with the water inlet channel 11 and the drain channel 12 . The movable seat 32 is disposed in the content chamber 312 ; and the movable seat 32 has an external thread portion 321 , a first end 322 and a second end 323 ; the external thread portion 321 is located between the first end 322 and the second end 323, and the movable seat 32 is engaged with the inner threaded portion 311; the needle valve 33 is arranged on the first end 322, and the needle valve 33 has a cylindrical shell 331, A guide space 332 and at least one longitudinal groove 333; the guide space 332 is located in the cylindrical shell 331; the longitudinal groove 333 is used to communicate the content chamber 312 and the guide space 332, and the The longitudinal grooves 333 have a groove width d of equal width (as shown in FIG. 6B ).

一控制部40，係設於該流道組件10上，該控制部40具有一驅動件41，該驅動件41係連結該第二端323，用以控制該活動座32以該外螺紋部321沿該內螺紋部311旋轉，進而連動該針閥33與該環形座20相對移動；並至少可移動至一全閉位置P1(如第4A、第5A及第6A圖所示)、一半開半閉位置P2(如第4B及第5B圖所示)及一全開位置P3(如第4C及第5C圖所示)。 A control portion 40 is disposed on the flow channel assembly 10 , the control portion 40 has a driving member 41 , and the driving member 41 is connected to the second end 323 for controlling the movable seat 32 to use the external thread portion 321 Rotate along the internal thread portion 311, and then move the needle valve 33 and the annular seat 20 relative to each other; and at least move to a fully closed position P1 (as shown in Figures 4A, 5A and 6A), half open and half open A closed position P2 (as shown in Figures 4B and 5B) and a fully open position P3 (as shown in Figures 4C and 5C).

藉此，當該針閥33位於該全閉位置P1(如第4A及第5A圖所示)時，該縱向剖溝333係未露出該環形座20(如第6A圖所示)，該針閥33阻斷該進水通道11與該排水通道12。 Therefore, when the needle valve 33 is at the fully closed position P1 (as shown in Fig. 4A and Fig. 5A ), the longitudinal groove 333 does not expose the annular seat 20 (as shown in Fig. 6A ), the needle The valve 33 blocks the water inlet channel 11 and the drain channel 12 .

又，當該針閥33位於該半開半閉位置P2(如第4B及第5B圖所示)時，該縱向剖溝333(如第6B圖所示)係露出該環形座20一第一長度H1，進而連通該進水 通道11與該排水通道12，此時該縱向剖溝333之露出面積係被定義為一半開半閉面積。 Also, when the needle valve 33 is in the half-open and half-closed position P2 (as shown in Figs. 4B and 5B), the longitudinal groove 333 (as shown in Fig. 6B) exposes a first length of the annular seat 20 H1, and then connect the influent For the channel 11 and the drainage channel 12, the exposed area of the longitudinal groove 333 is defined as a half-open and half-closed area.

並當該針閥33位於該全開位置P3(如第4C及第5C圖所示)時，該縱向剖溝333係露出該環形座20一第二長度H2，並連通該進水通道11與該排水通道12，該第二長度H2係為該第一長度H1之兩倍，此時該縱向剖溝333之露出面積係被定義為一全開面積，其係為該半開半閉面積的兩倍。 And when the needle valve 33 is at the fully open position P3 (as shown in Figs. 4C and 5C), the longitudinal groove 333 exposes a second length H2 of the annular seat 20 and communicates with the water inlet channel 11 and the water inlet channel 11. In the drainage channel 12, the second length H2 is twice the first length H1, and the exposed area of the longitudinal groove 333 is defined as a fully open area, which is twice the half-open and half-closed area.

當然，關於該縱向剖溝333的數量，雖於相關圖式中只繪出一個(例如第6B圖所示)，但此為示意用。實務上可修改數量為2個或更多個縱向剖溝333(圖中未示)，仍可達到相同之功效。 Of course, regarding the number of the longitudinal grooves 333 , although only one is drawn in the related drawings (eg, as shown in FIG. 6B ), this is only for illustration. In practice, the number can be modified to 2 or more longitudinal slits 333 (not shown in the figure), and the same effect can still be achieved.

實務上，該針閥裝置可再包括：一微動開關50，係電性連結該控制部。 In practice, the needle valve device may further include: a micro switch 50 which is electrically connected to the control unit.

該活動座32係對應該微動開關50，而又具有一觸動部324，其係鄰近該第二端323。 The movable seat 32 corresponds to the micro switch 50 and has a touch portion 324 adjacent to the second end 323 .

該觸動部324可為斜面段加凸出段之結構(如第4A、第4B及第4C圖所示)，並一體成型於該活動座32上。 The actuating portion 324 can be a structure of a slope section and a protruding section (as shown in FIGS. 4A , 4B and 4C ), and is integrally formed on the movable seat 32 .

藉此，當該針閥33從該全閉位置P1經該半開半閉位置P2，移動至該全開位置P3的過程，該第二端323係逐漸朝該微動開關50移動，並當該針閥33到達該全開位置P3，該觸動部324係啟動該微動開關50，該微動開關50係透過該控制部40停止該針閥33，使該針閥33準確停止於該全開位置P3。 Thereby, when the needle valve 33 moves from the fully closed position P1 to the fully open position P3 through the half-open and half-closed position P2, the second end 323 gradually moves toward the micro switch 50, and when the needle valve 33 reaches the fully open position P3, the trigger part 324 activates the micro switch 50, and the micro switch 50 stops the needle valve 33 through the control part 40, so that the needle valve 33 accurately stops at the fully open position P3.

在此要特別說明的部分是，關於第4A、第4B及第4C圖中，該縱向剖溝333因剖面角度不同而未予顯示，合先陳明。 The part to be particularly explained here is that, with respect to Figures 4A, 4B and 4C, the longitudinal sectional grooves 333 are not shown due to different sectional angles, and will be described first.

本案之設計重點在於： The design of this case focuses on:

第一：該針閥33設置該圓柱狀殼體331，其以等徑(該導引空間332亦為等徑設計)之柱體與該環形座20相對移動。 First: the needle valve 33 is provided with the cylindrical casing 331 , which moves relative to the annular seat 20 by a cylinder of equal diameter (the guiding space 332 is also designed with equal diameter).

第二：該圓柱狀殼體331設置該縱向剖溝333，該縱向剖溝333具有等寬之剖溝寬度d。 Second: the cylindrical casing 331 is provided with the longitudinal groove 333, and the longitudinal groove 333 has a groove width d of the same width.

藉由前述二個重點，使得該活動座32之移動量，與該縱向剖溝333露出該環形座20之長度成正比例，且為線性關係(如第10圖之第一線段L1所示)。 With the aforementioned two important points, the moving amount of the movable seat 32 is proportional to the length of the longitudinal groove 333 exposed to the annular seat 20, and has a linear relationship (as shown by the first line segment L1 in FIG. 10) .

進一步，該活動座32之移動量亦可與其旋轉圈數(亦即該外螺紋部321與該內螺紋部311之旋轉圈數)設計成正比(這部分的設計，可經由計算後製造成型該活動座32)，因此，只要控制旋轉圈數，即可等比例確定該縱向剖溝333露出該環形座20之長度，亦即等比例確定該進水通道11經該針閥組件30朝該排水通道20流動(流動過程如第3圖之箭頭所示)之流量。 Further, the moving amount of the movable seat 32 can also be designed to be proportional to the number of rotations (that is, the number of rotations of the external thread portion 321 and the internal thread portion 311 ) (this part of the design can be manufactured after calculation. The movable seat 32), therefore, as long as the number of rotations is controlled, the length of the longitudinal groove 333 exposed to the annular seat 20 can be determined proportionally, that is, the water inlet channel 11 can be determined proportionally to the drain through the needle valve assembly 30. The flow of the channel 20 (the flow process is shown by the arrow in Figure 3).

Through the ingenious design of this creation, the moving amount of the movable seat (including the guiding space) is linearly proportional to the length of the annular seat exposed from the longitudinal groove, and at the same time, the moving amount of the movable seat is also related to its rotation The number of rotations (that is, the number of rotations of the external thread portion and the internal thread portion) is proportional to the number of rotations. As long as the number of rotations is controlled, the length of the annular seat exposed by the longitudinal groove can be determined in equal proportions, that is, the length of the annular seat can be determined in equal proportions. The flow rate of the water channel flowing toward the drainage channel through the needle valve assembly. Therefore, the flow rate can be precisely controlled.

[2]可提高針閥移動之準確性。本創作設有微動開關，活動座則配合微動開關而具有觸動部，當活動座之針閥移動到全開位置，觸動部即啟動微動開關，微動開關透過控制部停止針閥，使針閥準確停止於該全開位置。故，可提高針閥移動之準確性。 [2] It can improve the accuracy of needle valve movement. This creation is equipped with a micro switch, and the movable seat is matched with the micro switch to have a trigger part. When the needle valve of the movable seat moves to the fully open position, the trigger part starts the micro switch, and the micro switch stops the needle valve through the control part, so that the needle valve stops accurately. in this fully open position. Therefore, the accuracy of needle valve movement can be improved.
