The purpose of this utility model is: to propose a hydraulic valve inner cavity cleaning device to simplify the operation steps, improve the cleaning quality and cleaning efficiency, and avoid damage to the valve body.

The technical scheme of the utility model is: a cleaning device for the inner cavity of the hydraulic valve, which is characterized in that it is composed of a bottom plate 1, an oil inlet pipe 2, an oil inlet nozzle 3, a cleaning pipe 4 and a screw plug 5; the bottom plate 1 is a rectangular plate, The bottom plate 1 is provided with drain holes arranged in an array with equal intervals. The oil inlet pipe 2 is a closed pipe with a rectangular cross-section. One side of the oil inlet pipe 2 is provided with 2 to 10 threaded holes arranged in a straight line. Equal oil distribution holes 2a, the center distance between two adjacent oil distribution holes 2a is greater than the maximum outer diameter of the hydraulic valve body to be cleaned, and an oil inlet nozzle 3 is installed on at least one end face of the oil inlet pipe 2, and the oil inlet pipe 2 passes through the screw Either welded or glued or the bracket is fixed on the base plate 1 near the edge, the side of the oil inlet pipe 2 with the oil distribution hole 2a is kept vertical, and the oil distribution hole 2a is facing the center of the base plate 1; the cleaning pipe 4 has a threaded joint at one end 1. A round pipe with the other end closed, the outer diameter of the cleaning pipe 4 is smaller than the inner cavity diameter of the hydraulic valve body to be cleaned, cleaning holes are evenly distributed on the outer cylindrical surface of the cleaning pipe 4, and the external thread of the threaded joint of the cleaning pipe 4 is in line with the The internal thread of the oil distribution hole 2a matches, the length of the cleaning pipe 4 is less than the inner cavity length of the hydraulic valve body to be cleaned, and the number of the cleaning pipe 4 is equal to the number of the oil distribution hole 2a; the external thread of the screw plug 5 and the oil distribution hole The internal thread of 2a cooperates, and the quantity of screw plug 5 is equal to the quantity of oil distribution hole 2a.

The utility model has the advantages of simplifying the operation steps, improving the cleaning quality and cleaning efficiency, and avoiding damage to the valve body. An embodiment of the utility model has been proved by experiments that the cleaning efficiency is increased by more than 5 times.

Detailed ways

Below the utility model is described in further detail. The inner cavity cleaning device of the hydraulic valve is characterized in that it consists of a bottom plate 1, an oil inlet pipe 2, an oil inlet nozzle 3, a cleaning pipe 4 and a screw plug 5; The oil drain holes are arranged in an array, and the oil inlet pipe 2 is a closed pipe fitting with a rectangular cross section. On one side of the oil inlet pipe 2, there are 2 to 10 threaded oil distribution holes 2a with equal intervals arranged in a line. The distance between the centers of two adjacent oil distribution holes 2a is greater than the maximum outer diameter of the hydraulic valve body to be cleaned, and an oil inlet nozzle 3 is installed on at least one end face of the oil inlet pipe 2, and the oil inlet pipe 2 is fixed by screws or welding or glued or brackets On the base plate 1 near the edge, the side of the oil inlet pipe 2 with the oil distribution hole 2a is kept vertical, and the oil distribution hole 2a faces the center of the base plate 1; the cleaning pipe 4 is a round pipe with a threaded joint at one end and a closed end at the other end. The outer diameter of the cleaning pipe 4 is smaller than the inner diameter of the hydraulic valve body to be cleaned, and there are cleaning holes evenly distributed on the outer cylindrical surface of the cleaning pipe 4, and the external thread of the threaded joint of the cleaning pipe 4 is consistent with the internal thread of the oil distribution hole 2a. Cooperate, the length of the cleaning pipe 4 is less than the inner cavity length of the hydraulic valve body to be cleaned, and the number of the cleaning pipe 4 is equal to the number of the oil distribution hole 2a; the external thread of the screw plug 5 matches the internal thread of the oil distribution hole 2a, and the screw plug 5 The quantity of plugging 5 is equal to the quantity of oil distribution hole 2a.

The working principle of the utility model is as follows: firstly, the cleaning device is placed on the cleaning workbench, the oil inlet nozzle 3 on the oil inlet pipe 2 is connected with the oil source through the pipeline, and according to the number of hydraulic valve bodies to be cleaned in one cleaning operation, the The threaded joints of the same number of cleaning pipes 4 are screwed into the oil distribution holes 2a, and the redundant oil distribution holes 2a are blocked with screw plugs 5 . The hydraulic valve body to be cleaned is placed outside the cleaning pipe 4, and the height of the hydraulic valve body can be adjusted by setting pads under the hydraulic valve body, so that the cleaning pipe 4 is located in the center of the hydraulic valve body cavity as much as possible. Then start the oil source, and the cleaning oil is sprayed from the cleaning hole of the cleaning pipe 4 to the internal cavity of the hydraulic valve, and then cleaning can be carried out. Due to the addition of automatic cleaning stations, the cleaning efficiency is greatly improved and the cleaning effect is improved.

In one embodiment of the present utility model, one side of the oil inlet pipe 2 is provided with four threaded oil distribution holes 2a at equal intervals, and the number of cleaning pipes 4 and screw plugs 5 is four.
