Abstract
Description
本發明係關於一種壓力閥,尤指一種調壓閥。The present invention relates to a pressure valve, and more particularly to a pressure regulating valve.
壓力閥通常用來將一進氣壓力降低至一所需的排氣壓力,且廣泛地用於各式各樣的裝置中;一種現有技術的調壓閥包含有一活動地設置在進氣口及出氣口之間的活塞,以選擇性地阻擋自高壓氣源至下游裝置的氣流,一彈簧設置在該活塞周圍,以推動該活塞朝向排氣口移動。當排氣壓力被設定在一預設壓力時,該彈簧的彈力會受到該排氣壓力而抵銷,則該活塞被推動以密封該進氣口,阻止氣體流過該壓力閥;當排氣壓力開始減低,該排氣壓力已不足以抵銷該彈簧的彈力,使得該活塞被推動而自該進氣口移開,允許該氣體流經該現有技術的壓力調節器。Pressure valves are commonly used to reduce an intake pressure to a desired exhaust pressure and are widely used in a wide variety of devices; a prior art pressure regulating valve includes an actively disposed inlet port and A piston between the air outlets to selectively block airflow from the high pressure air source to the downstream device, a spring disposed about the piston to urge the piston to move toward the exhaust port. When the exhaust pressure is set to a preset pressure, the spring force of the spring is offset by the exhaust pressure, and the piston is pushed to seal the air inlet to prevent gas from flowing through the pressure valve; The pressure begins to decrease, which is insufficient to offset the spring force of the spring, causing the piston to be pushed away from the air inlet, allowing the gas to flow through the prior art pressure regulator.
該現有技術的壓力閥利用不同的彈簧來預設所需要的排氣壓力,該複數彈簧具有公差,而使得該預設排氣壓力與所需要的排氣壓力不一致。為了減少此一差值,製造商必須改變彈簧,然因該預設排氣壓力只能在現有技術的閥力閥組裝後才能量測,故當該預設排氣壓力不匹配所需要的排氣口側壓力時,則製造商必須重組該壓力閥。因此,現有技術的壓力閥的製程將更為繁複。The prior art pressure valve utilizes different springs to preset the required exhaust pressure, the plurality of springs having tolerances such that the predetermined exhaust pressure is inconsistent with the required exhaust pressure. In order to reduce this difference, the manufacturer must change the spring, but since the preset exhaust pressure can only be measured after the prior art valve valve is assembled, when the preset exhaust pressure does not match the required row When the port side pressure is applied, the manufacturer must reassemble the pressure valve. Therefore, the process of the prior art pressure valve will be more complicated.
為克服該些缺陷,本發明提供一壓力閥來減輕或消除前揭問題。To overcome these deficiencies, the present invention provides a pressure valve to alleviate or eliminate the aforementioned problems.
本發明主要目的係提供一種調壓閥,其具有一不必經過重新組裝方可調整的預設排氣壓力。該調壓閥係包含有一閥體、一被動蓋以及一主動蓋;該被動蓋設置於該閥體的排氣口中,並抵止於該閥體內的活塞,且具有一傾斜邊。該主動蓋係可旋轉地抵靠在該被動蓋上,並具有一抵靠於該被動蓋的傾斜邊的另一傾斜邊;當該主動蓋相對於被動蓋旋轉時,該主動蓋的傾斜邊會推動該被動蓋,並使其向內或向外滑動;然後,該主動蓋的滑動可較多或較少地壓縮該閥體內的彈性件,來調整預設排氣壓力,而不必重新組裝該調壓閥。SUMMARY OF THE INVENTION A primary object of the present invention is to provide a pressure regulating valve having a preset exhaust pressure that is adjustable without having to be reassembled. The pressure regulating valve comprises a valve body, a passive cover and an active cover; the passive cover is disposed in the exhaust port of the valve body and abuts against the piston in the valve body and has a slanted edge. The active cover is rotatably abutted against the passive cover and has another inclined edge that abuts against the inclined edge of the passive cover; when the active cover is rotated relative to the passive cover, the inclined edge of the active cover The passive cover is pushed and slid inward or outward; then, the sliding of the active cover can compress the elastic member of the valve body more or less to adjust the preset exhaust pressure without reassembling The pressure regulating valve.

The active cover 30 includes a side wall, an inner end, an inclined side 31 and a notch 32. The inner end of the active cover 30 faces the outer end of the passive cover 20; the inclined edge of the active cover 30 is formed therein. The inner end of the active cover 30 abuts against the inclined side 21 of the passive cover 20; the recess 32 passes through the side wall and is formed in the inner end of the active cover 30. In an embodiment shown in FIG. 4, a plurality of teeth 311 are formed on the inclined side 31 of the active cover 30 and mesh with the tooth portion 211 of the passive cover 20 to be between the active cover 30 and the passive cover 20.

Adjustment.
請參閱圖2及圖3所示,該指示器40可旋轉地設置在該主動蓋30上,且避免與該主動蓋30分離。該指示器40具有一分割有複數段401、402、403的側壁;該指示器40之側壁的複數段401、402、403可選擇性地對應凹口32,並分別具有不同的標記來區別彼此;因此,當複數段401、402、403的其之一對應該凹口32時,只要留意不同的標示即可輕易地識別出那一段401、402、403對應凹口32;其中不同的標示可為不同顏色;在另一實施例,不同的標示可為不同的文字或符號。Referring to FIGS. 2 and 3, the indicator 40 is rotatably disposed on the active cover 30 and is prevented from being separated from the active cover 30. The indicator 40 has a side wall divided by a plurality of sections 401, 402, 403; the plurality of sections 401, 402, 403 of the side wall of the indicator 40 can selectively correspond to the recess 32 and have different indicia to distinguish each other Therefore, when one of the plurality of segments 401, 402, 403 corresponds to the notch 32, the corresponding notches 32 of 401, 402, and 403 can be easily recognized by paying attention to different indications; wherein different indications can be Different colors; in another embodiment, different labels may be different characters or symbols.
請參閱圖1、圖3、圖8及圖9所示,當一預設排氣壓力與一想要的排氣壓力不匹配時,可旋轉該主動蓋30來調整預設排氣壓力。當該主動蓋30相對於被動蓋20旋轉時,由於該被動蓋20係避免相對於該閥體10旋轉,故該主動蓋30的傾斜邊31會沿著該被動蓋20的傾斜邊21移動;當該主動蓋30的傾斜邊31會沿著該被動蓋20的傾斜邊21移動時,該主動蓋30會推動該被動蓋20向內或向外滑動至該閥體10的排氣口11。Referring to FIG. 1, FIG. 3, FIG. 8 and FIG. 9, when a predetermined exhaust pressure does not match a desired exhaust pressure, the active cover 30 can be rotated to adjust the preset exhaust pressure. When the active cover 30 is rotated relative to the passive cover 20, since the passive cover 20 is prevented from rotating relative to the valve body 10, the inclined edge 31 of the active cover 30 moves along the inclined side 21 of the passive cover 20; When the inclined edge 31 of the active cover 30 moves along the inclined side 21 of the passive cover 20, the active cover 30 will push the passive cover 20 to slide inward or outward to the exhaust port 11 of the valve body 10.
當被動蓋20向內滑動至該閥體10的排氣口11時,該被動蓋20推動該活塞12,使該彈性件31被壓縮更多。依據虎克定律,該彈性件13被壓縮愈多,則該彈性件13的力會愈大。因該彈性件13的力愈大,故需要更大的排氣壓力來適當地抵銷該彈性件13的力;因此,可提高該預設排氣壓力來匹配該所需要的排氣壓力。When the passive cover 20 is slid inwardly to the exhaust port 11 of the valve body 10, the passive cover 20 pushes the piston 12, causing the elastic member 31 to be compressed more. According to Hooke's law, the more the elastic member 13 is compressed, the greater the force of the elastic member 13. Since the force of the elastic member 13 is larger, a larger exhaust pressure is required to appropriately offset the force of the elastic member 13; therefore, the preset exhaust pressure can be increased to match the required exhaust pressure.
當該被動蓋20向外滑動到該閥體10的排氣口11時,該彈性件13會推動該活塞12;此時,該彈性件13被壓縮較少。依據虎克定律,該彈性件13被壓縮愈少,則該彈性件13的力會愈小。因該彈性件13的力愈小,故需要更小的排氣壓力來適當地抵銷該彈性件13的力;因此,可減低該預設排氣壓力來匹配該所需要的排氣壓力。When the passive cover 20 is slid outward to the exhaust port 11 of the valve body 10, the elastic member 13 pushes the piston 12; at this time, the elastic member 13 is compressed less. According to Hooke's law, the less the elastic member 13 is compressed, the smaller the force of the elastic member 13. Since the force of the elastic member 13 is smaller, a smaller exhaust pressure is required to appropriately offset the force of the elastic member 13; therefore, the preset exhaust pressure can be reduced to match the required exhaust pressure.
此外,該主動蓋30的凹口32與該被動蓋20的外端之間的空間,會隨著該被動蓋20向內或向外滑動至該閥體10的排氣口11而改變;然後,無論複數段401、402、403的那一段對應該凹口32,都會透過該空間而外露,並會隨之改變來指示壓力調整結果。In addition, the space between the recess 32 of the active cover 30 and the outer end of the passive cover 20 may change as the passive cover 20 slides inward or outward to the exhaust port 11 of the valve body 10; The segment corresponding to the plurality of segments 401, 402, 403, corresponding to the notch 32, will be exposed through the space and will change to indicate the pressure adjustment result.
前揭壓力閥具有如後所述多項優點,隨著該被動蓋20的傾斜邊21抵靠在該主動蓋30的傾斜邊31,當主動蓋30旋轉時會推動該被動蓋20向內或向外滑動到該閥體10;該被動蓋20的滑動造成該彈性件的壓縮差異,以調整該閥體10的預設排氣壓力。因此,該壓力閥的預設排氣壓力可依其所需加以調整,且無需重新將組裝前揭壓力閥。再者,該被動蓋20及主動蓋30之間調整結果,可容易地由該指示器40上複數段401、402、403的標示加以識別。The front pressure valve has a plurality of advantages as described later. As the inclined edge 21 of the passive cover 20 abuts against the inclined side 31 of the active cover 30, the passive cover 20 is pushed inward or toward the direction when the active cover 30 rotates. Sliding to the valve body 10; the sliding of the passive cover 20 causes a compression difference of the elastic member to adjust the preset exhaust pressure of the valve body 10. Therefore, the preset exhaust pressure of the pressure valve can be adjusted as needed, and there is no need to re-assemble the pressure valve before assembly. Moreover, the adjustment result between the passive cover 20 and the active cover 30 can be easily identified by the indication of the plurality of segments 401, 402, 403 on the indicator 40.
