Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinkler pumps, in particular to a fire sprinkler pump. Background Art

[0002] Fire sprinkler pump refers to the water supply device used in the sprinkler fire extinguishing system. It is an important equipment in fire protection engineering. It mainly provides the required pressure and flow for the sprinkler fire extinguishing system. When a fire occurs, it delivers fire fighting media such as clean water or foam liquid to the sprinkler head to remove the heat from the fire scene and prevent the spread of the fire. Fire sprinkler pumps are mainly divided into vertical fire pumps and horizontal fire pumps. The flow rate of the delivered liquid is one of the important performance data for the selection of fire pumps.

[0003] At present, in building fire protection systems, fire sprinkler pumps are used very rarely due to their specific usage scenarios and are basically in a static state. When left static for a long time, the pump body is easily stuck or rusted, resulting in the fire sprinkler pumps failing to play their due role in a fire. There are certain hidden dangers, and for this reason, improvements are proposed. Utility Model Content

[0011] Furthermore, the two manual components both include a handwheel, and the handwheel is arranged on the top of the shell, and the bottom of the handwheel is fixedly connected with a connecting shaft, and the connecting shaft passes through the shell and is fixedly connected to the adjacent third limit block, and the connecting shaft is rotatably connected to the shell to facilitate manual driving of the third limit block to rotate.

[0012] Furthermore, connecting pipes are fixedly connected to both sides of the outer surface of the shell, and the connecting pipes penetrate the shell and are fixedly connected with adjacent valve seats, and the connecting pipes can be connected to external pipelines.

[0013] Furthermore, two guide rails are fixedly connected between the inner walls on both sides of the shell, and the guide rails are slidably connected to the two pump bodies. The guide rails have a limiting effect on the pump bodies, which can ensure the stability of the movement of the pump bodies.

[0014] Furthermore, the two limiting grooves are matched with the first limiting block, the second limiting block and the third limiting block, and the second limiting block has a guiding limiting function, which enables the limiting groove to move smoothly to the first limiting block or the third limiting block.

[0015] Furthermore, the two second limit blocks are fixedly connected to the shell, and the shell has a fixed supporting function for the second limit blocks, which is beneficial to the installation of the second limit blocks.
