The invention discloses a vertical shaft microorganism induced advanced curtain and water stop plate comprehensive leaking stoppage method. The method comprises the following steps that S1, grouting is conducted on a crack of a bottom seal of a vertical shaft and a soil layer at the bottom of the bottom seal from the interior or exterior of the vertical shaft; s2, removing formation water and sludge in the vertical shaft; s3, a cushion block is arranged on the top face of the sealing bottom, and a water stop plate is hoisted to the cushion block; s4, grouting is conducted between the sealing bottom and the water stop plate through a grouting steel pipe of the grouting opening assembly, and vibration is conducted through a flat plate type vibrator while grouting is conducted till grouting is completed; and S5, secondary bottom sealing concrete is poured and vibrated compactly, so that secondary bottom sealing is formed. The method has the advantages that the microorganism slurry permeates into bottom sealing holes or cracks by utilizing the excellent fluidity, the concrete is induced to generate calcium carbonate deposition to bond a rock-soil material to block a seepage channel, and the strength of the bottom sealing concrete can be further improved; the waterstop plate can enhance the strength of the plain concrete shaft seal bottom and resist buoyancy and shear force of underground water to the shaft seal bottom.

The utility model discloses a pressure reducing valve impeller assembling tool which comprises a mounting frame, a fixing piece arranged on the mounting frame and used for fixing a valve body and a positioning piece used for guiding and positioning an impeller, and the fixing piece and the positioning piece are arranged oppositely. According to the pressure reducing valve impeller assembling tool, the space assembling position size of the valve body and the impeller can be rapidly positioned, the valve body and the impeller are accurately aligned and fastened and assembled, the quality problem that threads are damaged when the impeller is assembled is completely eradicated, assembling is efficient and rapid, and the production efficiency can be greatly improved.

This utility model relates to the field of throttling device technology, specifically a throttling device for a water purifier, including a throttling pipe. The inlet and outlet ends of the throttling pipe are respectively fixedly connected to an inlet pipe and a subsequent pipe via a first semi-circular sleeve and a second semi-circular sleeve, respectively, in cooperation with two sets of fixing components. An installation plate is fixedly connected to both ends of the throttling pipe. This utility model, through the combination of the first and second semi-circular sleeves and the fixing components, achieves rapid installation of the throttling pipe. Compared to the traditional method of connecting via multiple bolts and flanges, this connection structure requires no excessive tools and eliminates the need for repetitive and tedious bolt tightening operations, greatly simplifying the installation process, effectively saving installation time and labor costs, and significantly improving the convenience and efficiency of throttling pipe installation, making the entire water purifier assembly process faster and more efficient.

The present invention provides a material belt type upper cover assembly process, which produces the upper cover by material belt mode and then winds it, then feeds the upper cover through the material belt into the assembly production line of the connection seat, and then aligns and assembles the upper cover and the seat body, which makes the assembly quick and efficient. It includes: a. The upper cover is set on the upper cover feeding assembly line by material belt mode; b. The upper cover is clamped and separated from the material belt by a cutting mechanism on the upper cover feeding automation equipment; c. The seat body is pre-placed in the seat body positioning cavity, and the external linear drive mechanism drives the upper cover toward the seat body so that the upper cover is installed at the corresponding position of the seat body; d. Then the assembled seat body is removed, and the next seat body is positioned in the seat body positioning cavity, and continuous assembly operation is performed.

The invention discloses a vertical shaft microorganism induced advanced curtain and secondary bottom sealing plugging method. The method comprises the following steps that S1, grouting is conducted on cracks of a bottom sealing of a vertical shaft and a soil layer at the bottom of the bottom sealing from the interior or the exterior of the vertical shaft; s2, removing formation water and sludge in the vertical shaft; s3, a U-shaped ring beam is hoisted to the top face of the sealing bottom, and the U-shaped ring beam is fixed to the inner wall of the vertical shaft; hoisting a truss, and fixing the truss on the U-shaped ring beam to form a steel frame; and S4, secondary bottom sealing concrete is poured and vibrated compactly, so that secondary bottom sealing is formed.
