Description

Technical Field

[0001] The invention relates to the technical field of 120-type truck air control valves, and in particular to a cleaning machine for a main valve body of an air control valve. Background Art

[0002] 120 truck air control valve, its main valve body (see Fig.10 , Fig.11 ) has 10 inner cavities, and the top surface 31 and the bottom surface 33 of the main valve body 30 have a total of 10 holes 32 connected to the inner cavities respectively. The inner cavity must be kept clean before assembly, and no iron filings, dust and oil stains are allowed. For this reason, the main valve body needs to be cleaned for a long time before assembly. The existing cleaning method uses an external spray cleaning device to clean the main valve body. However, since the spray point is set outside the main valve body, the water flow through the inner cavity of the main valve body is very limited, which is far from meeting the cleaning requirements of the inner cavity of the main valve body, and the cleaning effect is poor. At the same time, the cleaning time is long and the cleaning cost is high. Connecting each inner cavity separately to achieve the cleaning function does not meet the requirements of mass production, which seriously reduces production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0031] The present invention will be described in detail below with reference to the accompanying drawings and the accompanying reference numerals.

[0032] like Figure 1-Figure 9 As shown, the main valve body cleaning machine of the air control valve comprises a box body 1 and a cleaning device arranged in the box body 1. The cleaning device comprises a horizontal tray plate 20 fixed in the box body 1, a plurality of cleaning valve seats 26 fixed on the upper surface of the horizontal tray plate 20, a positioning plate 2 fixed above the cleaning valve seat 26, a water distribution pipeline 7 connected to the cleaning valve seat 26, and a water inlet main pipe 6 connected to each water distribution pipeline 7. The cleaning valve seat 26 is provided with a cavity 27 connected to the water distribution pipeline 7, and the positioning plate 2 is provided with a water outlet hole 22 connected to the cavity of the cleaning valve seat 26. The number of the water outlet holes 22 on each positioning plate 2 is multiple and they are connected to the holes 32 on the top surface 31 or the bottom surface 33 of the main valve body 30 in a one-to-one correspondence. The positioning plate 2 is also provided with a positioning pin shaft 21 matched with the top surface 31 or the bottom surface 33 of the main valve body 30. The lower part of the box body 1 is a liquid storage cavity, the upper side wall of the box body 1 is provided with a water injection assembly 10, and the side wall of the box body 1 near the bottom is provided with a drainage assembly 14. A centrifugal pump 12 is provided outside the box body 1, and the inlet pipe 13 of the centrifugal pump 12 is connected to the liquid storage cavity, and the end of the outlet pipe 9 of the centrifugal pump 12 is connected to one end of the water inlet pipe 6, and the other end of the water inlet pipe 6 is blocked. A protective cover 5 is provided above the box body 1 to cover the cleaning device.

[0033] In this embodiment, the bottom surface of the cavity 27 of the cleaning valve seat 26 is an inclined surface 29 , and a through hole 28 connected to the water distribution pipeline 7 is opened on the side wall of the cleaning valve seat 26 near the lower end of the inclined surface 29 .

[0034] The water inlet main pipe 6 is located on one side of the horizontal pallet plate 20 close to the rear side wall 8 of the box body 1. Two left and right support seats 4 are respectively provided at the positions corresponding to the two ends of the water inlet main pipe 6 above the horizontal pallet plate 20. Horizontal pins 25 are respectively fixed on the two support seats 4 by screws 24. The two horizontal pins 25 are arranged opposite to each other and their axis centers coincide. The left and right sides of the protective cover 5 are hinged to the two horizontal pins 25. The axis center lines of the two horizontal pins 25 are the flipping axes of the protective cover 5. Two handles 15 are spaced apart on the side of the protective cover 5 away from the flipping axis. The handles 15 are overlapped on the upper edge of the front side wall 3 of the box body 1. The front edge of the horizontal tray plate 20 is connected to the front side wall 3 of the box body 1, the left edge of the horizontal tray plate 20 is connected to the left side wall of the box body 1, and a vertical baffle 18 is provided on the right side edge of the horizontal tray plate 20. The two ends of the vertical baffle 18 are respectively connected to the front and rear side walls 3 and 8 of the box body 1. A water drop channel is formed between the rear edge of the horizontal tray plate 20 and the rear side wall of the box body 1. A filter screen assembly 16 is provided between the liquid storage chamber of the box body 1 and the water drop channel. The end of the inlet pipe 13 of the centrifugal pump 12 is connected and fixed to the right side wall of the box body 1. A vertical partition 19 is provided in the liquid storage chamber of the box body 1. The vertical partition 19 divides the liquid storage chamber into a left chamber 23 and a right chamber 17. The area of ​​the left chamber 23 is larger than that of the right chamber 17. The right chamber 17 is connected to the inlet pipe 13 of the centrifugal pump 12. There are two drainage assemblies 14, one for the left chamber 23 and one for the right chamber 17. The water injection assembly 10 is located above the right chamber 17.

[0035] The right side wall of the box body 1 is provided with a flange connection port 11, and a heating device (omitted in the figure) is fixed at the flange connection port 11. The heating pipe of the heating device is inserted into the right cavity 17 of the liquid storage cavity for heating the cleaning liquid. The filter assembly 16 includes a filter support frame and a filter screen laid on the filter support frame to filter out impurities and oil in the cleaning liquid, which is conducive to reflux and repeated recycling. The protective cover 5 is composed of an arched cover body and side panels arranged at both ends of the arched cover body.

[0036] The number of the cleaning valve seats 26 is 6, among which the positioning plates 2 on three of the cleaning valve seats 26 have water outlet holes 22 corresponding one-to-one to the holes 32 on the top surface 31 of the main valve body 30; the positioning plates 2 on the remaining three cleaning valve seats 26 have water outlet holes 22 corresponding one-to-one to the holes 32 on the bottom surface 33 of the main valve body 30.

[0037] When in use, the six main valve bodies 30 are fixed on the positioning plates 2 of the six cleaning valve seats 26. The main valve bodies 30 are positioned by using the positioning pin shaft 21 and the mounting holes thereon. The six main valve bodies 30 are divided into two groups, one group with the top surface 31 facing downward and the other group with the top surface 31 facing upward, and are respectively connected to the corresponding cleaning valve seats 26 to ensure that the holes 32 on the top surface 31 or the bottom surface 33 correspond to and are connected to the water outlet holes 22 on the positioning plate 2. The cleaning liquid is injected into the box 1 through the water injection assembly 10, and the heating device is started for heating. After the set time, the centrifugal pump 12 is started. The centrifugal pump 12 lifts the cleaning liquid in the right cavity 17 of the box liquid storage cavity to the water inlet pipe 6, and then the water inlet pipe 6 is injected into each water distribution pipeline 7. The cleaning liquid passes through the cleaning valve seat 26 and the positioning plate 2 and enters each corresponding inner cavity of the main valve body 1. The cleaning liquid flowing out of the inner cavity outlet falls into the liquid storage cavity of the box 1 through the water drop channel and the filter assembly 16. After multiple uninterrupted flushing of the cleaning liquid pumped by the centrifugal pump 12, the inner cavity corresponding to the main valve body 30 is quickly flushed. After the set time, the two groups of main valve bodies 30 are disassembled and exchanged, and the above is repeated to complete the flushing of the remaining cavities.

[0038] During this process, the cleaning liquid can be filtered through the filter assembly 16 and then recycled by the centrifugal pump 12. Since the cleaning liquid falling into the left chamber 23 of the liquid storage chamber corresponds to multiple cleaning valve seats 26, the liquid concentration after cleaning is relatively high, and impurities that are not filtered can be precipitated in the left chamber 23, and the upper layer of liquid in the left chamber 23 overflows to the right chamber 17 for recycling. Finally, after all the main valve bodies 30 are cleaned, the cleaning liquid is discharged using the drainage assemblies 14 of the left and right chambers.

[0039] The above embodiments of the present invention are described in detail, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the invention should still fall within the scope of this patent.
