Description

A valve block structure for a hydraulic valve Technical Field

[0001] This utility model relates to the field of hydraulic valve technology, and in particular to a valve block structure for a hydraulic valve. Background Technology

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressurized oil of a distribution valve and is usually used in combination with a solenoid distribution valve. It can be used for remote control of the on / off of oil, gas and water pipeline systems in hydropower stations. It is commonly used in clamping, control and lubrication oil circuits. There are direct-acting and pilot-operated types, with pilot-operated types being more common.

[0003] Hydraulic valves are currently used in many conveying processes. Existing hydraulic valves require a valve block structure to limit the flow. Currently, the valve block is basically welded directly to the rotating rod of the hydraulic valve. This welding method is troublesome for later maintenance and increases costs. Therefore, we propose a valve block structure for hydraulic valves to solve the above problems. Summary of the Invention

A fixing bracket 305 is provided on the outside of the mounting bracket 301. The outer surface of the 305 has an insertion hole 306, and the outer surface of the fixing bracket 305 is connected to the valve block 4. Through the power component 2, the valve block assembly 3 can be easily driven to limit and cut off the flow inside the hydraulic valve housing 1. It is also slidably connected to the T-shaped slide rod 303 and the slide hole 302. The return force of the telescopic spring 304, the T-shaped slide rod 303 and the insertion hole 306 are adapted, and the fixing bracket 305 and the mounting bracket 301 are adapted. It can easily and quickly disassemble and replace the valve block 4 and reduce the maintenance cost.

[0023] The power assembly 2 includes a sealed bearing 201. A rotating rod 203 is connected to the inner ring of the sealed bearing 201. A geared motor 202 is connected to one end of the rotating rod 203. One end of the rotating rod 203 is connected to one side of the mounting bracket 301. The rotation of the geared motor 202 can easily drive the rotating rod 203 to rotate within the inner ring of the sealed bearing 201. In conjunction with the rotation of the rotating rod 203, the valve block 4 can simultaneously limit and cut off the flow inside the hydraulic valve housing 1. A connecting plate 8 is connected to the outer surface of the geared motor 202. One side of the connecting plate 8 is connected to the outer surface of the hydraulic valve housing 1. The connecting plate 8 can improve the stability of the geared motor 202 and prevent it from swaying. Two support frames 9 are connected to the outer surface of the hydraulic valve housing 1. Two mounting holes are opened on one side of each support frame 9. The support frames 9 and mounting holes can be used to easily fix the equipment to the ground and prevent it from shifting.

[0024] The hydraulic valve housing 1 is provided with a sealing shell 5 on the outside. One side of the sealing shell 5 and one side of the hydraulic valve housing 1 are connected to a flange 6. A set of fixing screws 7 are provided on the outside of the sealing shell 5. By adapting the sealing shell 5 to the hydraulic valve housing 1 and the fixing screws 7 to the flange 6, the hydraulic valve housing 1 can be opened and closed conveniently and quickly. One end of the telescopic spring 304 is connected to one side of the T-shaped slide rod 303 and the other end of the telescopic spring 304 is connected to the outer surface of the mounting bracket 301. The fixing bracket 305 is adapted to the mounting bracket 301 and the T-shaped slide rod 303 is adapted to the insertion hole 306, which can improve the stability of the T-shaped slide rod 303.

[0025] The working principle of this utility model is as follows:

[0026] During initial assembly, pull the T-shaped slide bar 303 forward, which will stretch the telescopic spring 304 and place the valve block 4 into the hydraulic valve housing 1. Simultaneously, align the mounting bracket 301 with the fixing bracket 305, and insert the fixing bracket 305 into the mounting bracket 301. Then, release the T-shaped slide bar 303, and the rebound force of the telescopic spring 304 will allow the T-shaped slide bar 303 to insert into the sliding hole 302 and the insertion hole 306. Simultaneously, align the two flange plates 6 horizontally and seal them using the fixing screws 7. The device is then transported to the location of use. Next, the support frame 9 is fixed to the ground using mounting holes and mounting screws as needed. One end of the sealing shell 5 and one end of the hydraulic valve shell 1 are connected to the pipeline. The reduction motor 202 is started as needed. The rotation of the reduction motor 202 causes the rotating rod 203 to rotate in the inner ring of the sealing bearing 201. The rotation of the rotating rod 203 causes the valve block 4 to limit and cut off the flow inside the hydraulic valve shell 1. The above is the complete usage process of this utility model.
