This application discloses a valve stem sealing structure, relating to the field of valve stem sealing technology, including a valve body and a gland. The gland is fastened to the valve body by bolts, and a sealing groove is formed on the upper part of its inner wall, housing an O-ring that fits onto the valve stem. A sealing cavity is formed on the inner wall of the valve body, and multiple sealing modules are provided, including, from top to bottom, a dynamic seal, an elastic sealing assembly, a pair of wedge-shaped sealing packings, and a flexible graphite braided packing. The elastic sealing assembly includes an upper support, a lower support, and a spring disposed between them. Tightening the bolts generates an axial preload, driving the inner and outer protruding lips of the dynamic seal to press tightly against the valve stem and the inner wall of the sealing cavity, respectively, and compressing the sealing packings and packing. This structure, through multiple sealing combinations, significantly improves the reliability, stability, and leakage resistance of the valve stem seal.

A method for the assembly of a stairlift guide rail (100), the method involving the use of a kit comprising a plurality of segments of guide rail, each segment of the plurality of segments comprising a first face (211) and a second face (212), wherein each tapered segment comprises a protruding lip (220) extending from a first one of said first face and said second face, and a second one of said first face and said second face comprising a recess (351) for receiving a lip 220 of an adjacent tapered segment (210), wherein each segment (210) comprises a through-hole (221) extending across said recess (351) and each lip (220) protruding of each segment (210) comprises a through-hole (221), such that when a lip (220) of an adjacent segment (210) is inserted in said recess (351) said through- holes (221) of said lip (220) and said segment (210) are aligned, and the two adjacent segments are joint by inserting a bolt (231) through said aligned through-holes and fixing said bolt with a nut (232), wherein the radial outer surface (472) of the nut (232) comprises a tapered surface (473), such that when the nut (232) is pulled into the through-hole (221) by rotating the bolt (231) the nut (232) acts as a wedge on the lip (220), thereby pulling the lip (220) and the segment (210) attached thereto tightly towards and against the adjacent segment (210).

A pillbox whose body takes the form of a thin cylinder with a shallow body in the middle separated into separate “pockets” by walls erected through the diameter of the body to form two or more equal segments of the body (ambiguous to pizza slices). A circular top and bottom then cover the body in order to have the cylinder sealed off at the top and bottom whilst still being hollow on the inside. The cylinder's ring side lack walls, thus making the segments of the body into cavities of equal sizes whose openings encompass the ring side of the cylinder. A sleeve does, however, wrap snugly around the ring side of the cylinder, possessing a square opening roughly the same size as one of the cavities of the cylinder. The sleeve is then held in place by two protruding lips (one at the top and one at the bottom) of the cylinder due to the top and bottom sides of the cylinder overhanging the ring side itself. Due to this, the ring sleeve cannot move up or down the depth of the cylinder and is thus stuck in place, however, can still rotate around the ring side of the cylinder.

A panel, which, at two opposite edges, includes coupling parts that allow joining by a downward movement, the coupling parts including a male part that fits in a female part, wherein the male part comprises a laterally protruding lip with at a lower side a downward facing support surface.

To provide a gasket that can suppress corrosion of the contact surface to which it is applied. [Solution] The sealing device 1 comprises an elastic body portion 2 formed from an elastic material. The elastic body portion 2 has a fitting portion 10 which is an annular part, a lip 20 which is an annular part that protrudes inward from the fitting portion 10, and an annular first projection 30. The lip 20 protrudes inward from the inner end portion 10a of the fitting portion 10, inclined inward. The length l of the protruding lip 20 is set based on the minimum crushing allowance c when the pipe is maximally eccentric with respect to the through hole. The first projection 30 protrudes inward from the inner end portion 10a of the fitting portion 10.

The invention provides a fitting for a window, comprising a fitting assembly (1) attachable in a fitting groove (7) provided in a window profile (8), a rotatable arm (2) having a shaft channel (15), and a shaft (3) having a widened head (24) at one end and a radially projecting lip (25) at the other end. The fitting assembly is provided with a body (5) and a passage opening (14). In the assembled state of the fitting, the arm is rotatably connected to the main body of the fitting assembly with the lip of the shaft hooked on the main body using the shaft disposed in the channel opening and the shaft channel, with the main body and the arm being enclosed between the lip and the widened head of the shaft.

A panel, which, at two opposite edges, includes coupling parts that allow joining by a downward movement, the coupling parts including a male part that fits in a female part, wherein the male part comprises a laterally protruding lip with at a lower side a downward facing support surface.

The utility model discloses an air direct pressure pinch valve neck bush lip type closing device which comprises a neck bush body, at least two sections of protruding lip bands are arranged in the middle of the neck bush body, the lip bands are elastic and attached to the inner wall of the neck bush body, the broken portions of the lip bands form lip corner structures, and the lip corner structures are connected with the neck bush body. When the outer side of the neck bush main body is compressed by air to close an inner channel of the neck bush, the inner walls of the lip bands are attached to each other or attached to the inner wall of the neck bush main body to seal the channel; according to the design, a plurality of lip bands are additionally arranged in the channel of the neck bush, and the lip bands of the neck bush have good elasticity, so that the neck bush does not need to be pushed by large air pressure to tightly close the pinch valve through the lip bands, the stress burden of the whole neck bush can be relieved, and the lip angle structure further facilitates the closing effect of the neck bush; the operation condition is improved, the service life is prolonged, the safety of the pinch valve is improved, and driving energy is saved.
