New Description: [New Technology Field] This new type relates to a multi-functional fluid two-way check valve, especially one that can produce a two-way backstop effect when a high pressure fluid is passed. [Prior Art] • Press, the tire air compressor currently used on the market is _ directly mounted on the nozzle of the tire for inflating the pressure value inside the tire. The conventional tire air compressor mainly includes a gas nozzle, a pressure gauge and an air intake controller, and is connected to an air compressor, so that the user can control the air intake controller to control the high pressure generated by the air compressor. Air is supplied to the inside of the tire via the air nozzle, and the tire is internally measured by the pressure gauge at the same inlet. However, because the pressure value is difficult to set, it often causes the internal pressure of the tire to be too large or insufficient. It is necessary to repeatedly release or pressurize the internal gas pressure of the tire, which may cause inconvenience in charging or danger in driving. • The tire pressure detector disclosed in the Republic of China Patent No. 578706 is a tire pressure detector directly installed inside the tire. Although it can facilitate the detection of internal pressure of the tire pressure, it often causes dismantling. It is inconvenient to install. In order to further facilitate the installation and use of the tire pressure detector, it is gradually changed - the tire pressure detector is directly mounted on the tire nozzle outside the tire, but it is also difficult to inflate the tire. It is difficult to correctly set the pressure inside the tire to provide the correct and appropriate tire pressure. See also Fig. 2 2 for a conventional fluid two-way check valve. The fluid two-way check valve mainly comprises a hollow sleeve i〇, a M30655.4 connection sleeve 20, a gas nozzle 30, a first, a fourth, a second valve body 5〇, a pressure adjustment group #6〇 And - intake joint 7. .

However, the above-mentioned conventional fluid two-way check valve is applied to the tire pressure detector, in addition to providing a high-pressure gas output in a unidirectional manner in a forward or reverse direction, and may be used to provide a set tire pressure, and Excess high pressure gas or fluid is discharged from the outside. However, the conventional fluid two-way check valve must still vent excess excess high pressure gas to the outside through the originally inflated path (i.e., from the intake joint) when excess high pressure gas is exhausted. Because both the intake air and the deflation flow through the same path, it often causes mutual interference during inflation and deflation, resulting in unstable pressure during inflation, and further causes the pressure in the tire to be filled to not accurately reach the desired setting. Pressure, bandits are very good. Furthermore, the conventional fluid two-way check valve can not hold the pressure value inside the tire after the completion of the filling operation, but needs to be filled from time to time, then the V 1 F system is maintained. The pressure value, or must be additionally extracted by the pressure gauge ^, ^, ^ ' caused to make M306554 [new content] The main purpose of this new i is to provide a multi-functional fluid two-way check valve, which will provide a reverse way Excess fluid is discharged to the outside world.

At this time, the fluid two-way check valve The connecting sleeve 750 and the air nozzle 500 are sleeved on the air inlet 610, and the high pressure gas is injected from the air inlet hole 410 of the air inlet joint 400, and the injected high pressure gas is along the air inlet hole 410. The second accommodating chamber 730 is moved downward by the high pressure gas pushing the first valve body 200 against the elastic force of the first compression spring 722, so that the high pressure gas can enter the first through the through hole 310 of the second valve body 300. The 18 M306554 chamber 720 is accommodated, and sequentially passed through the air nozzle 50 0, the connecting sleeve 750 and the air inlet nozzle 61 〇 into the tire 60 俾 '俾 to inflate the tire. Please refer to the figure 6 The schematic diagram of the multi-functional fluid two-way anti-exhaustion gas filling according to the fourth preferred embodiment of the present invention exceeds the pressure setting value. In the present embodiment, when the high-pressure gas inside the tire 6 is filled, the high-pressure gas is exceeded. When the set pressure value is set (the set pressure value can be adjusted by the above description by adjusting the intake air The head 400 is screwed to the screwing stroke at the upper end of the second accommodating chamber 730. The inside of the tire 600 will be overstressed, overcoming the elastic force of the second compression spring 73 2, and the excess high pressure gas is passed through The air inlet 610 is reversely overflowed in such a manner that excess high-pressure gas will sequentially pass through the connecting sleeve 750, the air nozzle 500 and the first accommodating chamber 72, thereby pushing the first valve body 200 upward. The first valve body 200 and the second valve body 300 are in close contact with each other to be in an airtight state, thereby preventing the high pressure gas from continuing to be poured into the tire β 0 0 from the outside of the fluid two-way check valve 1. Further, the excess south pressure The gas can increase the internal pressure of the tire 600, and the second valve body 3〇〇 is moved upward, and the second airtight ring 332 and the oblique shoulder stop portion of the second valve body 3〇〇 are released. The airtight state of 740 causes the excess pressure gas to overflow to the outside through the vent hole 735, thereby maintaining the proper pressure inside the tire 600, and avoiding excessive high pressure gas being poured into the tire via the fluid-two-way check valve 1. 600 in the middle. - Referring to Figure 6c, the multi-function 3b fluid two-way check valve relating to the fourth embodiment of the present invention shows the intention that the internal gas pressure of the tire has reached a set value. In the above-mentioned 6B, it is mentioned that when the internal gas pressure of the tire 6 exceeds the set value, the excessive high-pressure gas overflows to the outside of the 19 M306554 through the vent hole 735. When the gas gradually overflows, the gas pressure inside the tire _ is gradually reduced; when the excessive high pressure gas is overflowed to reach the pressure setting value set by the tire _, the second compression spring m will be according to: the elastic force will be the second "The downward direction is moved to the bottom of the second accommodation chamber 73", j causes the second airtight ring 332 to abut against the oblique shoulder stop portion 74, and maintains the airtight state, thereby stopping the operation of the deflation. Maintain the pressure setting inside the tire 6〇〇.
再者，輪胎600内部之氣體壓力係經由氣嘴5〇〇及穿 孔776而與谷置裱肖850相連通，因此，輪胎内部之壓力 亦直接反應至容置環槽850。當灌入於輪胎6〇〇内部的壓 力值逐漸升高時，容置環槽850内部的壓力亦隨之升高， 並推動浮動環840及承載環83〇上移。當輪胎6〇〇内部所 灌注的高壓氣體的壓力值達到一設定值時，此時承載環 8 3 0將同時可上移至綠色的第一指示色環8 1 2内之位置， 使紅色的第二指示色環8 3 2被綠色的第一指示色環81 2所 迫蔽’俾使使用者由壓力指示裝置8 〇 〇外側觀視時，僅可 看到綠色的第一指示色環812，藉以達到告知使用者所灌 注的高壓空氣已達到設定值。 明參閱弟7圖所示’係有關本新型第四較佳實施例之 多功能流體雙向逆止閥顯示輪胎内部氣體壓力未達設定 值時的示意圖。如圖所示，當輪胎6〇〇使用一段長久時間 後’在在會因為漏氣或其他外在因素使得輪胎6 0 0内部高 壓氣體產生洩漏，並使輪胎6〇〇内部壓力亦逐漸地降低。 此時壓力指示裝置8〇〇的浮動環840下方的容置環槽850 20 M306554 内部^力亦將同時降低，故將使得承載環83G及浮動環 通著輪I β 〇 〇内部壓力的逐漸降低，而同時向下方移 動。當承載環840位置下移至脫離綠色的第一指示色環 81 2之相對應位置時，使用者將可由壓力指示裝置8⑽外 側觀視到紅色的第二指示色環832，藉此達到一警示效 果俾使使用者可以輕易即時得知輪胎6 Μ内部壓力不足 之狀態。Further, the gas pressure inside the tire 600 communicates with the valley 850 via the nozzle 5 and the through hole 776, so that the pressure inside the tire directly reacts to the accommodation ring groove 850. When the pressure value of the inside of the tire 6 is gradually increased, the pressure inside the ring groove 850 is also increased, and the floating ring 840 and the carrier ring 83 are pushed up. When the pressure value of the high-pressure gas injected inside the tire 6〇〇 reaches a set value, the carrier ring 830 will be simultaneously moved up to the position of the green first indicator color ring 8 1 2 to make the red The second indicator color ring 8 3 2 is obscured by the green first indicator color ring 81 2 'when the user views the outside of the pressure indicating device 8 , only the green first indicator color ring 812 is visible. In order to inform the user that the high pressure air that has been perfused has reached the set value. Referring to the drawing of Figure 7, the multi-function fluid two-way check valve relating to the fourth preferred embodiment of the present invention shows a schematic diagram when the internal gas pressure of the tire does not reach a set value. As shown in the figure, when the tire 6 〇〇 is used for a long period of time, the internal high pressure gas of the tire 600 is leaked due to air leakage or other external factors, and the internal pressure of the tire 6 逐渐 is gradually lowered. . At this time, the internal force of the accommodating ring groove 850 20 M306554 under the floating ring 840 of the pressure indicating device 8 亦 will also be lowered at the same time, so that the internal pressure of the bearing ring 83G and the floating ring through the wheel I β 逐渐 will be gradually reduced. While moving down at the same time. When the position of the carrier ring 840 is moved down to the corresponding position of the green indicating color ring 81 2, the user will be able to view the red second indicating color ring 832 from the outside of the pressure indicating device 8 (10), thereby achieving a warning. The effect is that the user can easily know the state of the internal pressure of the tire 6 即时.
