    • A liquid flow generation apparatus (100) comprising a working chamber (105) and a corresponding drive region (106) for holding liquid from a liquid source (800); a conduit (120) and a check valve (110) fluidly coupled to the drive region (106); an intermediate tank (125) located at an elevated position, configured to receive and store the held liquid from the working chamber and to discharge the stored liquid in response to the stored liquid exceeding a first threshold volume; a drive member (115) operable to reciprocate through a push stroke, in which the drive member (115) moves from a first position to a second position to drive the held liquid from the drive region (106) through the check valve (110), and a pull stroke, in which the drive member (115) moves from the second position to the first position to allow flow of further liquid from the liquid source (800) into the drive region (106); and a reciprocation tank (140) having a tank weight smaller than the weight of the drive member (115), the reciprocation tank (140) cooperatively connected to the drive member (115), configured to collect the discharged liquid from the intermediate tank (125) to increase the tank weight to cause the drive member (115) to perform one of the push and pull strokes, and to release the collected liquid in response to the collected liquid exceeding a second threshold volume to generate a liquid flow and to cause the drive member (115) to perform the other of the push and pull strokes.

    • A valve assembly is provided.It includes:a valve body (1);a valve seat (11,12) disposed in an inner chamber of the valve body (1); and a valve plug (2) capable of moving relative to the valve seat (11,12). The valve seat (11,12) includes a first valve seat (11) and a second valve seat (12) disposed longitudinally; the valve plug (2) includes a first contact portion (21) and a second contact portion (22), the first contact portion (21) is capable of contacting the first valve seat (11) to form a seal, the second contact portion (22) includes an annular protrusion (20) being deformable after being extruded with the second valve seat (12), the second contact portion (22) is capable of forming a seal by contacting the second valve seat (12) through the deformed protrusion (20'),and the valve body (1) has a blocking part (19) which is capable of blocking rotation of the valve plug (2). With the annular protrusion (20) disposed on the valve plug (2), the protrusion (20) can be deformed in an extrusion manner, so as to achieve a sealing effect of the valve plug (2) and the valve seat (11,12),which omits precise maching on the valve plug (2) and the valve seat (11,12).
    • 提供了一种阀组件,包括:一阀体(1);一阀座(11,12),设置在阀体(1)的内腔中; 以及能够相对于所述阀座(11,12)移动的阀塞(2)。 阀座(11,12)包括纵向设置的第一阀座(11)和第二阀座(12) 阀塞(2)包括第一接触部分(21)和第二接触部分(22),第一接触部分(21)能够接触第一阀座(11)以形成密封件,第二接触部分 (22)包括在与第二阀座(12)挤压之后可变形的环形突起(20),第二接触部分(22)能够通过使第二阀座(12)穿过变形突起 (20'),并且阀体(1)具有能够阻止阀塞(2)的旋转的阻挡部(19)。 通过设置在阀塞(2)上的环状突起(20),突起(20)能够以挤出方式变形,从而实现阀芯(2)和阀座(11)的密封效果, 12),其省略了在阀塞(2)和阀座(11,12)上的精确加工。
