The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-7, an outer cage type throttling valve core comprises a valve rod 1, wherein a valve core 2 is installed on the valve rod 1, an installation seat 3 is fixedly arranged at the bottom of the valve core 2, an installation piece 4 is installed on the installation seat 3 in an adapting mode, and the installation piece 4 is located at the bottom of the valve core 2 and sleeved on the outer side of the installation seat 3. The mounting 4 is provided with mounting 5 below, and the top of mounting 5 is provided with screw thread post 51, and the one side of mounting 4 below mounting 5 is provided with fixing base 6 to install soft fixed column 61 on the fixing base 6. It should be noted that, the valve rod 1 and the valve core 2 are both installed in the valve seat in an adaptive manner, and the specific working principle and working mode of the valve rod 1 and the valve core 2 in the valve seat are all the existing technologies disclosed in the market at present, and neither belong to the main technical features to be solved in the technical scheme, so that redundant description is omitted in the utility model.

Wherein, the middle part of installed part 4 has seted up mounting hole 41, and the bottom of mount pad 3 is fixed perpendicularly downwards and is provided with screw thread cover 31 to screw thread cover 31 passes in the mounting hole. The parts of the outer side of the threaded sleeve 31, which are in contact with the mounting holes 41, are paved with sealing bodies, and the threaded holes on the threaded sleeve 31 are matched with the threaded columns 51. By providing a sealing body outside the threaded sleeve 31, the sealability of the device can be improved, thereby preventing external fluid from entering the mounting seat 3.

Wherein, the bottom of mounting 4 is provided with a plurality of sealing washer 8 in the outside of mounting hole 41 to the top of mounting 5 corresponds sealing washer 8 and all adapts to and has seted up seal groove 81. Through the adaptation setting between sealing washer 8 and the seal groove 81, can further improve the leakproofness of this device to further prevent outside fluid from getting into in the mount pad 3.
