Description

Technical Field

[0001] The utility model relates to a hydraulic valve core induction quenching waste cooling liquid discharge device, belonging to the field of hydraulic valve core processing. Background Art

[0002] The hydraulic valve core is an important part of various valve assemblies. The valve body uses its movement to achieve the basic functions of direction control, pressure control or flow control. During the induction heat treatment process, a large amount of metal slag will be generated and mixed in the quenching liquid in the water tank, which brings great trouble to the cleaning of the quenching liquid. The quenching liquid in the water tank needs to be evacuated, and then new liquid is added and stirred while being evacuated again. It is not easy to clean the metal slag, which increases the amount of quenching liquid used. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hydraulic valve core induction quenching waste coolant discharge device to solve the problems raised in the above background technology. The utility model reduces the amount of quenching liquid and water, reduces the discharge of waste liquid, and reduces production costs.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a hydraulic valve core induction quenching waste coolant discharge device, comprising a water trough, the bottom of the water trough is an inclined surface, the lowest point of the inclined surface is provided with a strip-shaped opening, a bottom box for gathering metal slag is provided directly below the strip-shaped opening, the bottom box is connected and fixed to the water trough, a detachable elbow for connecting a water pump is installed at the bottom of the bottom box, a partition is provided at the upper position inside the bottom box, two support rods are symmetrically installed on the lower surface of the partition, the lower end of the support rod is in contact with the bottom of the bottom box, a V-shaped groove is processed on the upper surface of the partition, a plurality of vertical holes are opened in the V-shaped groove, and a straight pipe is installed at the lower position in the vertical hole.

[0005] Furthermore, the end of the curved pipe away from the bottom box is provided with a first flange connected and fixed to the curved pipe, the end of the curved pipe close to the bottom box is provided with a second flange connected and fixed to the curved pipe, and the first flange is connected to the bottom box by multiple screws.

[0006] Furthermore, a convex ring is provided between the second flange and the bottom box, the convex ring is connected and fixed to the bottom box, the screw passes through the second flange and is threadedly connected to the convex ring, the area of ​​the bottom box covered by the convex ring is provided with a circular opening concentrically arranged with the convex ring, and one end of the bent pipe is inserted into the convex ring.

[0007] Furthermore, a sealing sleeve is provided on one end of the bent pipe close to the second flange, and the sealing sleeve is in contact with the inner wall of the convex ring.

[0008] Furthermore, a bottom frame is provided directly below the sink, and two symmetrically arranged first poles are connected and fixed to one side of the upper surface of the bottom frame, and the upper ends of the first poles are connected and fixed to the sink, and two second poles are symmetrically installed on the side of the upper surface of the bottom frame away from the first poles, and the upper ends of the second poles are connected and fixed to the bottom box.

[0009] Furthermore, two threaded blind holes are symmetrically provided on the lower surface of the partition, an outer surface of the upper end of the support rod is processed with an external thread, and one end of the support rod processed with the external thread is threadedly connected in the threaded blind hole.

[0010] Beneficial effects of the utility model:

[0011] 1. The molten metal slag produced by the induction quenching of the hydraulic valve core moves to the strip-shaped mouth along the inclined surface of the water tank under the action of gravity, and then falls into the bottom box through the straight pipe, realizing the centralized collection of the molten metal slag in the water tank. One end of the bent pipe is connected to the liquid inlet end of the water pump. When the water pump is working, the molten metal slag gathered in the bottom box and the quenching liquid in the water tank are discharged together. Because the molten metal slag gathers in the bottom box, the time spent on discharging the molten metal slag in the bottom box is shortened. At this time, less quenching liquid is discharged from the water tank, thereby reducing the amount of quenching liquid and water, reducing the discharge of waste liquid, and reducing production costs.

[0012] 2. A partition is installed at the upper part of the bottom box to separate the internal space of the bottom box. Under the action of the V-shaped groove, the metal slag can smoothly pass through the straight pipe into the bottom box. When the water pump is working, the channel formed by multiple straight pipes is smaller than the strip-shaped opening. Therefore, the flow rate of the quenching liquid in the water tank increases when passing through the straight pipe. The quenching liquid with increased flow rate will impact the metal slag in the bottom box, so that the metal slag in the bottom box is mixed with the quenching liquid and then discharged, further reducing the amount of quenching liquid required to discharge the metal slag in the bottom box.

[0013] 3. Align the second flange with the convex ring, then pass the screws through the second flange and thread them into the convex ring to complete the assembly of the elbow and the bottom box, thereby partially increasing the thickness of the bottom box mounting screw area.

The area of ​​the bottom box 5 covered by the convex ring 8 is provided with a circular opening concentrically arranged with the convex ring 8, so that one end of the elbow 7 is inserted into the convex ring 8, and the sealing The sleeve 16 fits against the inner wall of the convex ring 8 to improve the sealing between the elbow 7 and the convex ring 8. The metal slag generated by the induction quenching of the hydraulic valve core moves to the strip-shaped mouth 12 along the inclined surface on the water tank 1 under the action of gravity, and then the metal slag falls into the bottom box 5 through the straight pipe 11, thereby concentrating the metal slag in the water tank 1 and connecting one end of the elbow 7 to the liquid inlet end of the water pump. When the water pump is working, the metal slag gathered in the bottom box 5 and the quenching liquid in the water tank 1 are discharged together. Since the metal slag gathers in the bottom box 5, the time spent on discharging the metal slag in the bottom box 5 is shortened.

A straight pipe 11 is installed at the lower position of the vertical hole, and a straight pipe 11 is installed at the bottom A partition 10 is inserted into the upper position of the box 5 to separate the internal space of the bottom box 5. Under the action of the V-shaped groove, the metal slag can smoothly pass through the straight pipe 11 into the bottom box 5. When the water pump is working, the channel formed by the multiple straight pipes 11 is smaller than the strip-shaped opening 12. Therefore, the flow rate of the quenching liquid in the water tank 1 increases when passing through the straight pipe 11. The quenching liquid with increased flow rate will impact the metal slag in the bottom box 5, so that the metal slag in the bottom box 5 is mixed with the quenching liquid and then discharged, further reducing the amount of quenching liquid required to discharge the metal slag in the bottom box 5.
