The utility model relates to the technical field of valves, in particular to a high-sealing-performance stop valve which comprises a valve body provided with a flow channel, a valve cover installed on the valve body, a valve rod penetrating through the valve cover and extending into the valve body and a valve clack connected with the valve rod and located in the valve body. A valve seat located below the valve clack is arranged in the valve body. A connecting structure is arranged between the valve clack and the valve rod and comprises a fixing block arranged on the valve rod, a fixing groove formed in the valve clack and a limiting ring. The fixing block is arranged in the fixing groove in a sliding mode, one side of the valve clack abuts against one end of the valve rod, and the peripheral face of the joint of the valve clack and the valve rod is sleeved with the limiting ring. Through the arrangement of the connecting structure, when the valve rod extrudes the valve clack and the valve clack extrudes the valve seat, force can be uniformly applied, so that the problem of side leakage caused by a gap between the valve clack and the valve seat due to non-uniform stress of the valve clack is reduced.

This invention relates to the field of pipeline temperature control switch technology, and more particularly to a temperature control valve, comprising a valve body, a valve core, a temperature control unit, and a drive device. The valve body has an inlet channel and an outlet channel separated by a partition, and the partition has a connecting port. The valve core includes a push block positioned above the connecting port, with multiple arc teeth on its lower part. The output end of the drive device is connected to the push block. A sleeve is provided on the push block, with one end of a rotating rod connected to the output end of a drive motor, and the other end threadedly connected to the sleeve. The drive device causes the push block to gradually move towards the connecting port, and the lower part of the arc teeth gradually enters the connecting port. Water flowing through the connecting port exits through the channel between two arc teeth. Multiple channels between adjacent arc teeth form a multi-channel structure, reducing pressure loss and side leakage, greatly improving the performance of this temperature control valve. The threaded connection allows for more precise control of the channel opening size and flow rate ratio, resulting in more accurate temperature control.

The application provides a preparation system for hardware production, which comprises a container, a fixed rod is fixedly connected to the inner surface bottom end of the container, a telescopic rod is slidably connected to the inside of the fixed rod, a fixed disc is fixedly connected to the upper end outer surface of the telescopic rod, a protective plate is fixedly connected to the upper end outer surface of the fixed disc, an overflow hole is formed in the outer surface of the protective plate, a fixed plate is fixedly connected to the inner surface of the container close to the top end, and a liquid outlet is arranged in the container. The device can reduce the degree of spattering of molten metal liquid when it is added into the container, and can prevent the molten metal liquid from shaking and leaking to the side during transportation by arranging the fixed plate, further reducing the contact area of the molten metal liquid with air, reducing the heat loss in the container, thereby improving the safety of the device during use, and further improving the use efficiency of the device.

The utility model belongs to can production equipment, and discloses an edible mushroom can bottling device which comprises a cuboid hopper, a plurality of inverted-circular-truncated-cone-shaped discharging barrels are evenly arranged in the center of the lower end of the cuboid hopper in the length direction of the cuboid hopper, and discharging openings of the discharging barrels are slightly smaller than can bottle openings. Turntables in one-to-one correspondence with the multiple discharging barrels are arranged at the position, located on one side of the multiple discharging barrels, of the lower end of the cuboid funnel, the outer edges of the turntables exceed the corresponding discharging openings, annular grooves sunken downwards are coaxially formed in the turntables, and the bottoms of the annular grooves are tightly attached to and matched with the outer diameters of the discharging openings; a feeding opening slightly larger than the inner diameter of the discharging openings is formed in the groove bottom of the annular groove, conveying belts which are in one-to-one correspondence with the discharging openings are arranged below the discharging openings, the conveying direction of the conveying belts is perpendicular to the length direction of the cuboid hopper, and a plurality of can bottle limiting grooves matched with the bottoms of can bottles are evenly formed in the conveying belts in the conveying direction of the conveying belts; the device has the advantages that the product quality can be effectively guaranteed, and continuous automatic production is facilitated.

This utility model discloses an incontinence-eliminating and odor-removing sanitary pad, comprising: absorbent particles, first absorbent particles, a soft cotton surface layer, a flow-guiding layer, and a leak-proof layer. The soft cotton surface layer is disposed above the flow-guiding layer, and the leak-proof layer is disposed below the flow-guiding layer. A first filling groove is recessed in the top surface of the flow-guiding layer, and the first absorbent particles are disposed in the first filling groove. A second filling groove is recessed in the top surface of the flow-guiding layer, located outside the first filling groove, and the absorbent particles are disposed in the second filling groove. This incontinence-eliminating and odor-removing sanitary pad increases absorbency, meeting the needs of women with urinary incontinence, reducing side leakage of urine and odor from the sides, and effectively locking in odor during use.
