Description
本新型係與幫浦有關，特別是關於一種活塞式加壓幫浦。This new type is related to the pump, especially regarding a piston type pressurized pump.
習用之活塞式加壓幫浦係於一管體內設置一活塞，該管體具有分別用以接收及排放液體之一入口及一出口，該活塞與該管體的入口之間形成一第一容室，該活塞與該管體的出口之間形成一第二容室，且該活塞具有一使該第一、第二容室連通之通孔。當該活塞朝該出口的方向滑移時，該第二容室內的液體係以高壓自該出口排出；當該活塞朝該入口的方向滑移時，該第一容室內的液體會經由該活塞之通孔補充至該第二容室。藉此，該活塞式加壓幫浦能接收一般供水設備(例如水龍頭)提供的水，再以高壓將水排出，以供灑水設備或噴霧設備使用。The conventional piston type pressurized pump is provided with a piston in a tube body, and the tube body has an inlet for receiving and discharging liquid and an outlet, and a first volume is formed between the piston and the inlet of the tube body. a second chamber is formed between the piston and the outlet of the tube body, and the piston has a through hole for communicating the first and second chambers. When the piston slides in the direction of the outlet, the liquid system in the second chamber is discharged from the outlet at a high pressure; when the piston slides in the direction of the inlet, the liquid in the first chamber passes through the piston The through hole is added to the second chamber. Thereby, the piston type pressurized pump can receive water supplied from a general water supply device (for example, a faucet), and then discharge the water at a high pressure for use in a sprinkling device or a spray device.
然而，前述活塞式加壓幫浦在排出液體時，該第二容室內的液體有部份會自該活塞之通孔回流至該第一容室，使得該幫浦提供之液體壓力不如預期。而且，該活塞朝該入口之方向滑移產生之壓力會阻礙液體自該入口進入該第一容室，甚至使該第一容室內的水從該入口逆流而出，使得流入該第二容室的水量不足，進而降低該活塞下一行程排出液體的壓力。However, when the piston type pressurized pump discharges the liquid, a part of the liquid in the second chamber is returned from the through hole of the piston to the first chamber, so that the liquid pressure provided by the pump is not as expected. Moreover, the pressure generated by the piston sliding in the direction of the inlet prevents the liquid from entering the first chamber from the inlet, and even causes the water in the first chamber to flow backward from the inlet, so that the second chamber flows into the second chamber. The amount of water is insufficient, which in turn reduces the pressure of the liquid discharged from the next stroke of the piston.
換言之，習用之活塞式加壓幫浦無法穩定地提供高壓液體，因而仍有待改進。In other words, the conventional piston type pressurized pump cannot stably supply a high pressure liquid, and thus there is still room for improvement.
有鑑於上述缺失，本新型之主要目的在於提供一種活塞式加壓幫浦，能穩定地提供高壓液體。In view of the above-mentioned deficiencies, the main object of the present invention is to provide a piston type pressurized pump capable of stably supplying a high pressure liquid.
為達成上述目的，本新型所提供之活塞式加壓幫浦包含有一加壓缸及一滑移裝置。該加壓缸具有相對之一第一側及一第二側、一用以讓液體進入該加壓缸內之入口，以及一用以讓液體從該加壓缸排出之出口。該滑移裝置係能滑移地設於該加壓缸，該滑移裝置包含有一活塞及一第一逆止閥，該活塞能於該加壓缸之第一側與第二側之間往復滑移，該活塞與該加壓缸第一側之間形成一第一容室，該活塞與該加壓缸第二側之間形成一第二容室，該入口及該出口分別與該第一容室及該第二容室連通，且該活塞具有一與該第一容室及該第二容室連通之通道，該第一逆止閥係設於該通道，用以阻止該第二容室內的液體經由該通道進入該第一容室。藉此，該幫浦在排放液體時，該第一逆止閥可防止該第二容室內的液體回流至該第一容室，進而使該幫浦能穩定地提供高壓液體。In order to achieve the above object, the piston type pressurized pump provided by the present invention comprises a pressurizing cylinder and a slipping device. The pressurizing cylinder has a first side and a second side opposite to each other, an inlet for allowing liquid to enter the pressurizing cylinder, and an outlet for discharging liquid from the pressurizing cylinder. The slip device is slidably disposed on the pressurizing cylinder, the slip device includes a piston and a first check valve, and the piston can reciprocate between the first side and the second side of the pressurizing cylinder Sliding, a first chamber is formed between the piston and the first side of the pressurizing cylinder, and a second chamber is formed between the piston and the second side of the pressurizing cylinder, and the inlet and the outlet respectively respectively a chamber and the second chamber are in communication, and the piston has a passage communicating with the first chamber and the second chamber, the first check valve is disposed in the passage to block the second Liquid in the chamber enters the first chamber via the passage. Thereby, the first check valve prevents the liquid in the second chamber from flowing back to the first chamber when the liquid is discharged, thereby enabling the pump to stably supply the high pressure liquid.
另外，該加壓缸之入口可朝向一與該滑移裝置的滑移方向垂直之方向，以避免該活塞朝該加壓缸第一側之方向滑移產生之壓力阻礙液體自該入口進入該第一容室。而且，該加壓缸之入口可更設有一第二逆止閥，用以阻止該第一容室內的液體從該入口流出，則更可確保液體不會從該入口逆流而出。如此一來，該幫浦能更穩定地提供高壓液體。In addition, the inlet of the pressurizing cylinder may be oriented in a direction perpendicular to the slip direction of the slip device to prevent the pressure of the piston from sliding toward the first side of the pressurizing cylinder to hinder the liquid from entering the inlet. The first chamber. Moreover, the inlet of the pressurizing cylinder may further be provided with a second check valve for preventing the liquid in the first chamber from flowing out of the inlet, thereby ensuring that the liquid does not flow out from the inlet. In this way, the pump can supply high pressure liquid more stably.
