Description

膨脹閥 Expansion valve

本創作係與膨脹閥有關，更詳而言之係指一種結構簡單並能有效縮減體積之膨脹閥。 This creation is related to expansion valves, and more specifically to an expansion valve that is simple in construction and effective in reducing volume.

按，請參第一圖及第二圖，係習知一種膨脹閥之構造，其主要包含有一閥體1、一設於該閥體1內之磁鐵套筒2及一設於該磁鐵套筒2內之轉軸3，該轉軸3可受磁場作用而旋轉並進行上、下之位移，以調節供流體(如冷媒)流過之流量大小。 Referring to the first and second figures, a structure of an expansion valve is known, which mainly comprises a valve body 1, a magnet sleeve 2 disposed in the valve body 1, and a magnet sleeve disposed thereon. In the inner shaft 3, the rotating shaft 3 can be rotated by the magnetic field and moved up and down to adjust the flow rate of the fluid (such as refrigerant).

惟，由於轉軸3之位移行程必須受到控制，因此會在轉軸3之上方設置一行程控制組件4，該行程控制組件4具有套置在該轉軸3頂端上之彈簧5及一設置在該閥體1內部之支架6，該支架6並與該彈簧5勾接，使該轉軸3在位移之過程中，造成該彈簧5與該支架6之相對位置改變，進而達到控制轉軸3位移行程之目的。 However, since the displacement stroke of the rotating shaft 3 must be controlled, a stroke control assembly 4 is disposed above the rotating shaft 3, and the stroke control assembly 4 has a spring 5 sleeved on the top end of the rotating shaft 3 and a valve body disposed thereon. 1 The inner bracket 6 is hooked to the spring 5, so that the relative position of the spring 5 and the bracket 6 is changed during the displacement of the rotating shaft 3, thereby achieving the purpose of controlling the displacement stroke of the rotating shaft 3.

然而，由於彈簧5具有相當之長度，因此必須採用較長之轉軸3方足以供彈簧5套入，但較長之轉軸3便必須使用較大體積之閥體1加以容置，因此習知之膨脹閥，不僅需要較多之額外零件，更有著體積較大之問題。 However, since the spring 5 has a considerable length, it is necessary to use a longer shaft 3 for the spring 5 to be inserted, but the longer shaft 3 must be accommodated by the larger volume of the valve body 1, so that the conventional expansion Valves not only require more extra parts, but also have larger problems.

有鑑於此，為改善先前技術中，習知膨脹閥有著零件過多及體積過大之問題；本創作乃提供一種膨脹閥，包含有一閥體、一磁鐵套筒、一固定螺套及一轉軸；該閥體具有一流道、一容室及一連通該流道與該容室之開口，該容室內之頂部位置具有一上限位凸耳，該磁鐵套筒係位於該閥體之容室內，該磁鐵套筒之頂面凸出有至少一上限位凸部，該磁鐵套筒之底面凸出有至少一下限位凸部，該固定螺套係位於該閥體之容室內，並與該閥體固接，該固定螺套具有一貫穿之螺孔及一自該固定螺套底端一側凸出之下限位凸耳，該轉軸係穿經該磁鐵套筒，並具有一螺桿，該螺桿與該固定螺套之螺孔螺接，而可受外力作用進行直線之上、下位移，以調節通過該閥體開口之流體流量；藉以達到簡化構件及縮減體積之功效。 In view of this, in order to improve the prior art, the conventional expansion valve has too many parts and The problem is that the volume is too large; the present invention provides an expansion valve including a valve body, a magnet sleeve, a fixing nut sleeve and a rotating shaft; the valve body has a first-class passage, a chamber, and a communication passage and the passage An opening of the chamber, the top position of the chamber has an upper limit lug, the magnet sleeve is located in the chamber of the valve body, and the top surface of the magnet sleeve protrudes with at least one upper limit convex portion, the magnet sleeve The bottom surface of the cylinder protrudes from at least one lower limit convex portion, and the fixing screw sleeve is located in the cavity of the valve body and is fixedly connected to the valve body, the fixing screw sleeve has a through hole and a fixing screw a lower limit lug protruding from one side of the bottom end, the rotating shaft passing through the magnet sleeve and having a screw threadedly screwed with the screw hole of the fixing screw sleeve, and being able to be externally acted upon by a straight line The lower displacement is used to adjust the flow of the fluid through the opening of the valve body; thereby achieving the effect of simplifying the member and reducing the volume.

是以，上述即為本創作一較佳實施例所提供之一種膨脹閥100各部構件及其組裝方式之介紹，接著再將其使用特點說明如下： Therefore, the above description is a description of each component of the expansion valve 100 and its assembly manner provided by a preferred embodiment of the present invention, and then its use characteristics are as follows:

當於本創作之磁鐵套筒20內導入電流而產生磁場時，該轉軸40便會受到磁場所驅動而沿一旋向進行旋轉，由於該轉軸40之螺桿412與該固定螺套30之螺孔31螺接，因此該轉軸40便能進行直線上移、或直線下移(由磁場方向控制)。 When a current is generated in the magnet sleeve 20 of the present invention to generate a magnetic field, the rotating shaft 40 is driven by the magnetic field to rotate in a direction of rotation, because the screw 412 of the rotating shaft 40 and the screw hole of the fixing nut 30 31 is screwed so that the shaft 40 can be moved up linearly or linearly downward (controlled by the direction of the magnetic field).

當該轉軸40直線下移時，該閥針42會封抵於該閥體10之開口112(如第五圖所示)中，使該流道111內之流體(如冷媒)無法流通，且該磁鐵套筒20隨著轉軸40下移之同時，該下限位凸部22會抵觸於該固定螺套30之下限位凸耳32上，以停止再導入電流於該磁鐵套筒20中，以便停止該轉軸40之位移。 When the rotating shaft 40 moves straight down, the valve needle 42 seals against the opening 112 of the valve body 10 (as shown in FIG. 5), so that the fluid (such as refrigerant) in the flow channel 111 cannot flow, and When the rotating shaft 40 moves downward, the lower limit convex portion 22 will abut against the lower limit lug 32 of the fixing nut 30 to stop re-introducing current into the magnet sleeve 20, so that The displacement of the shaft 40 is stopped.

當該轉軸40直線上移時，該閥針42會自該閥體10之開口112(如第六圖所示)脫離，使該流道111內之流體(如冷媒)得以流通，且該磁鐵套筒20隨著轉軸40上移之同時，該上限位凸部21會抵觸於位在該容室121頂部位置之該上限位凸耳51上，以停止再導入電流於該磁鐵套筒20中，以便停止該轉軸40之位移。 When the rotating shaft 40 moves straight up, the valve needle 42 will open from the valve body 10. The port 112 (as shown in the sixth figure) is disengaged, so that the fluid (such as refrigerant) in the flow path 111 can be circulated, and the upper limit convex portion 21 of the magnet sleeve 20 interferes with the rotation axis 40. The upper limit lug 51 is located at the top position of the chamber 121 to stop re-introducing current into the magnet sleeve 20 to stop the displacement of the shaft 40.

是以，由於本創作於該磁鐵套筒20之頂、底面分別凸出上限位凸部21與下限位凸部22及於該閥體10容室121頂部位置之上限位凸耳51與該固定螺套30底端一側所凸出之下限位凸耳32，以作為該轉軸40位移行程極限位置之限位控制。不僅無須再另行增設習知之行程控制組件，而能減少所需之構件，更能無須增設供習知之行程控制組件容置之空間，而能大幅地縮減體積與重量，以達到適用性更佳之功效。 Therefore, since the top and bottom surfaces of the magnet sleeve 20 are respectively protruded from the upper limit convex portion 21 and the lower limit convex portion 22 and the upper limit lug 51 at the top position of the chamber body 121 of the valve body 10 and the fixing The lower limit lug 32 protruding from the bottom end side of the screw sleeve 30 is used as the limit control of the displacement stroke limit position of the rotary shaft 40. Not only does it need to add a conventional stroke control component, but it can reduce the required components, and it can increase the volume and weight of the stroke control component without the need to add space for the applicability. .
