  • Patent number: 11930619
    Abstract: A plug-in pump installation structure of a cooling distribution unit is disclosed. A pump seat is disposed in a machine case and has a fixed joint. A plug-in pump has a pump main body and a moveable joint. The plug-in pump is plugged or removed relative to the pump seat through the moveable joint and the fixed joint being connected or released. One distal end of each rotary arm of a handgrip has a latching hook. The rotary arms are pivotally connected at opposite sides of the pump main body. When the handgrip is folded on the machine case, the latching hook abuts against a protrusion disposed on a block piece of the machine case, when the handgrip is rotated to be away from the machine case, the latching hooks of the rotary arm is released from the abutted protrusion.

  • Patent number: 11913562
    Abstract: In an implementation, a hydraulic valve includes a valve body, a cylindrical chamber within the valve body, and a cylindrical spool within the chamber. The spool is rotatable between at least a first position and a second position about a longitudinal axis parallel to a longitudinal axis of the chamber. The spool includes a landing and an eccentric channel that extends around a portion of an outer circumferential surface of the landing. In the first position, an inlet and an outlet of the hydraulic valve are fluidly coupled by the eccentric channel to allow a flow of a hydraulic fluid circumferentially around the landing from the inlet to the outlet. In the second position, the inlet and/or the outlet are obstructed by another portion of the outer circumferential surface of the landing to prevent the flow of the hydraulic fluid from the inlet to the outlet.

  • Patent number: 11892115
    Abstract: A method of cutting and removing a section of prestressed concrete cylinder pipe and then installing a replacement valve while the pipeline is fully pressurized uses a replacement valve body with two cylinders that match the openings of the cut pipe. Inside each of the two cylinders is a cut-covering assembly which includes a cylindrical elastomeric seal and a mechanical linkage to move the seal in and out of the cut pipe. The replacement valve body further includes a rotatable valve in a central portion of the valve, and when the cylinder ends of the replacement valve body are positioned adjacent the bores of cut pipe ends, the valve can be rotated to move linkage assemblies that control the elastomeric seals in and out of each of the cut-covering assemblies into the bores of the cut pipe ends, thereby covering gaps created when the pipe was cut and placing the pipe ends in fluid-tight engagement with the replacement valve body.

  • Patent number: 11839903
    Abstract: A vacuum pumping system which comprises a plurality of vacuum pumping arrangements for evacuating a flammable gas stream and exhausting the gas stream through an exhaust outlet. A housing houses the vacuum pumping arrangements and forms an air flow duct for an air flow for mixing with the exhaust gas stream output from the exhaust outlet in a mixing region in the housing. An airflow generator generates an air flow through the air flow duct to cause mixing of air with the flammable gas stream to a percentage of the flammable gas in the air flow lower than the lower flammability limit of the flammable gas. An airflow sensor senses the flow of air for determining if the air flow is sufficient to dilute the flammable gas to lower than said percentage.
