The utility model relates to the technical field of heating, in particular to a pressure tapping pipe and gas water heating equipment, and the pressure tapping pipe comprises a pipe body provided with a containing cavity; a partition part is arranged in the containing cavity of the pipe body, a water outlet is formed in the partition part, and the partition part divides the containing cavity into a first cavity and a second cavity; the pipe body is provided with a drainage end, a first connecting end and a second connecting end, and the first connecting end and the second connecting end are respectively communicated with the first cavity; the switch valve mechanism comprises a reset piece and a sealing piece, and the reset piece is suitable for applying thrust towards the water outlet to the sealing piece so that the sealing piece can abut against the separation part and seal the water outlet. According to the embodiment of the utility model, through the arrangement of the switch valve mechanism, when the condensate water in the pressure tapping pipe is more, the water outlet can be automatically opened, so that the condensate water is discharged, the accurate detection of the wind pressure switch is ensured, and the normal operation of heating equipment is further ensured.

The invention discloses a bridge combined multi-stage energy consumption buffering device which comprises a steel jacket box, a steel partition plate for partitioning space is arranged in the steel jacket box, and a first-stage energy consumption structure for first-stage buffering energy consumption and a second-stage energy consumption structure for second-stage buffering energy consumption are arranged in the partitioned space. The steel jacket box is arranged outside the pier through the rubber fender. The UHPC panel and the stainless steel composite steel plate are adopted, and the service life of the structure is remarkably prolonged under the complex service environment of a water area. In the aspect of collision resistance, the system has a definite deformation mode induction mechanism, the collision force is dispersed through the UHPC panel with the large rigidity, the collision force is buffered through the honeycomb with the small rigidity, the collision force is transmitted to the high-strength steel grating structure through the UHPC and the dense honeycomb, the energy consumption efficiency is greatly improved, the force transmission path is reasonable, coverage of different anti-collision grades can be achieved, and the system is suitable for popularization and application. And meanwhile, the compression stroke of the energy dissipation assembly is increased, the peak impact force is reduced, and designability is good.

The invention relates to the technical field of gaskets, in particular to a conductive sealing gasket structure of enamel equipment, which comprises a polytetrafluoroethylene jacket and a metal corrugated elastic ring gasket, the two end faces of the metal corrugated elastic ring gasket are fixedly connected with the end faces of the two asbestos-free or graphite-free filling layers respectively, the inner side faces of the metal corrugated elastic ring gasket and the asbestos-free or graphite-free filling layers are fixedly connected with the inner side face of the polytetrafluoroethylene clamping sleeve, and wedge-shaped grooves are formed in the inner side face of the polytetrafluoroethylene clamping sleeve. According to the conductive sealing gasket structure for the enamel equipment, the chemical corrosion resistance and hardness of tetrafluoroethylene are not changed, the compression stroke of the gasket is large, the sealing performance is excellent, the conductive and sealing performance is achieved at the same time, the enamel equipment does not need to be adjusted at all, the service life of the enamel equipment is prolonged, and the service life of the enamel equipment is prolonged. Cost is low and efficiency is high.

The utility model discloses a sealed big stroke with wire formula micro switch, belongs to micro switch technical field, including the press handle of axially mobile setting in the shell, and the press handle one end is located the outside of shell as operating end, and the other end is located the inside of shell and is equipped with the first step surface of radial protruding, the press handle inside axially is provided with small spring and lower end and is equipped with the push rod of second step surface, the push rod lower end sets up in the base and passes through the inside step limit hole of base and is contacted with micro switch unit, the press handle outside is equipped with big spring and is pre -compression between the first step surface of press handle and the inner wall step surface of base, small spring is contained in the inner chamber of press handle, and is pre -compression in the upper end surface of push rod. This switch has solved the problem that the existing micro switch is damaged internal structural member because of small stroke and is easy to cause overpressure when installing and using, and has reduced the installation precision of switch to driving mechanism.

The patent relates to the technical field of vehicle seats, in particular to a pneumatic high-lift damping seat, which comprises a seat body, a mounting bottom plate and a height adjusting assembly. The height adjusting assembly comprises an inner cylinder, an outer cylinder, a gas spring, an unlocking handle, a cable, a locking pin, a locking plate, a fixing plate and a support plate. The gas spring is fixed inside the inner cylinder and the outer cylinder. The fixing plate is fixedly connected with the top of the gas spring. The support plate is fixed at the bottom of the inner cylinder. The unlocking handle is rotationally connected with the fixing plate. The locking pin is slidingly connected with the support plate. The locking plate is fixed on the inner wall of the outer cylinder. The locking pin can be inserted into the locking plate through the inner cylinder. The two ends of the cable are respectively connected with the unlocking handle and the locking pin. The unlocking handle is linked with the locking pin through the cable. The height of the seat body can be adjusted by pressing or releasing the pressure, so that the height of the seat body can be adjusted in a large range and quickly. The problem that the height adjusting range of the existing vehicle seat is small and not suitable for special vehicle seats is solved.
