止回閥這種類型的閥門的作用是只允許介質向一個方向流動，而且阻止反方向流動。通常這種閥門是自動工作的，在一個方向流動的流體壓力作用下，閥瓣打開；流體反方向流動時，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動。

The purpose of this type of valve is to allow the medium to flow in only one direction and prevent flow in the opposite direction. Usually this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-coincident valve flap of the valve flap act on the valve seat, thereby cutting off the flow.

其中止回閥就屬于這種類型的閥門，它包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機構，還有一個像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達閥座面的合適位置，閥瓣設計在鉸鏈機構，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、的與閥座接觸。閥瓣可以全部用金屬制成，也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面，這取決于使用性能的要求。旋啟式止回閥在*打開的狀況下，流體壓力幾乎不受阻礙，因此通過閥門的壓力降相對較小。升降式止回閥的閥瓣坐落位于閥體上閥座密封面上。此閥門除了閥瓣可以自由地升降之外，其余部分如同截止閥一樣，流體壓力使閥瓣從閥座密封面上抬起，介質回流導致閥瓣回落到閥座上，并切斷流動。根據使用條件，閥瓣可以是全金屬結構，也可以是在閥瓣架上鑲嵌橡膠墊或橡膠環的形式。像截止閥一樣，流體通過升降式止回閥的通道也是狹窄的，因此通過升降式止回閥的壓力降比旋啟式止回閥大些，而且旋啟式止回閥的流量受到的限制很少

Among them, the check valve belongs to this type of valve, which includes swing check valve and lift check valve. Swing check valves have a hinge mechanism and a door-like disc that rests freely on the sloping seat surface. In order to ensure that the valve disc can reach the proper position of the valve seat surface every time, the valve disc is designed in the hinge mechanism, so that the valve disc has enough swing space and makes the valve disc really contact the valve seat. The disc can be made entirely of metal, or inlaid with leather, rubber, or synthetic overlays, depending on the performance requirements. In the fully open condition of the swing check valve, the fluid pressure is almost unimpeded, so the pressure drop across the valve is relatively small. The disc of the lift check valve is located on the sealing surface of the valve seat on the valve body. Except that the valve disc can rise and fall freely, the rest of the valve is like a globe valve. The fluid pressure lifts the valve disc from the sealing surface of the valve seat, and the backflow of the medium causes the valve disc to fall back to the valve seat and cut off the flow. According to the conditions of use, the disc can be of all-metal structure, or it can be in the form of a rubber pad or rubber ring embedded on the disc holder. Like the globe valve, the passage of fluid through the lift check valve is also narrow, so the pressure drop through the lift check valve is larger than that of the swing check valve, and the flow of the swing check valve is limited rare

啟閉件靠介質流動的力量自行開啟或關閉，以防止介質倒流的閥門叫止回閥。止回閥屬于自動閥類，主要用于介質單向流動的管道上，只允許介質向一個方向流動，以防止發生事故。

The valve that opens or closes by the force of the medium flow to prevent the backflow of the medium is called a check valve. The check valve belongs to the automatic valve category, which is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents.
