Meanwhile, as no head space is required in this case, the arrangement distance of the head joint can be compressed as much as possible, which is beneficial to the design of the color changing valve to be more compact.
The cleaning module 19 of the present invention is used to clean the paint residues of a color in the common flow path 14 before color changing, and the paint residues can be cleaned by first using a solvent and then dried by air, or cleaned by mixing the solvent and air into a mist and then dried by air, and in short, the cleaning step requires the supply of the solvent and air. Thus, cleaning module 19 has two supply connections 29 for supplying cleaning solvent or cleaning air, both connections requiring the installation of a non-return valve 36 in order to avoid contamination by paint flowing backwards. The cleaning paint and the cleaning air are controlled by the paint valve 10, and the opening and the closing of the paint valve 10 are realized by the corresponding control air.
The cleaning air and the cleaning solvent flow to the front color changing module 20 through the common flow channel 14, but different from the condition that the common flow channel 14 of the color changing module 20 penetrates through a valve block, the length of the common flow channel 14 of the cleaning module 19 is only half of the thickness of the cleaning valve body 27 and is only connected to the outlet 41 of the paint valve, because the tail support 35 is arranged at the rear of the cleaning module 19 and does not have the outlet of the common flow channel 14, if the common flow channel 14 of the cleaning module 19 is penetrated, a blind end which does not lead to the outside is formed at the rear half part of the channel of the paint valve 10, the paint is accumulated in the blind end of the channel and cannot be cleaned, and in order to avoid the formation of the blind end, the channel of the cleaning module is only communicated with the channel of.
After paint is supplied into the valve body 6, the paint can enter the common flow channel 14 through the control of the paint valve 10, when the paint valve 10 is closed, the paint flows back circularly from the return joint 30, and a section of the channel from the paint supply to the return is a channel with a closed inner part, namely the second flow part 22, and cannot be directly processed, so that the channel needs to be opened from the outer side of the valve body 6, and then the outer side is blocked by the plug 38 to form a closed inner channel.
The control gas of the present invention enters the paint valve 10 to control the opening and closing of the paint valve 10. Similarly to the above, there are internal closed channels that cannot be directly processed, that is, the fourth flow part 24 and the fifth flow part 25, which are also opened from the outside, and then the outside part is closed to form the internal channel.
According to the invention, when paint leaks due to failure of the internal seal of the paint valve 10, the leaked paint can flow out through the leakage checking hole 37, so that the paint valve 10 with problems can be observed and found in time, and greater risks can be avoided.
The top of each module 2 is provided with a first inclined surface 3 and a second inclined surface 4, the top of each module 2 is provided with at least two joints 5, the joints 5 are arranged on the second inclined surface 4, the joints 5 are obliquely arranged, one oblique side of each joint corresponds to the sending direction of an oil-gas pipe, the oil-gas pipes are bent less by the oblique joint installation mode, the pipes are more flexible and have small stress, the oblique arrangement saves the installation space of the joints 5, the joints 5 are convenient to disassemble and assemble, and the oblique joint is matched with the arrangement of an internal flow passage of the valve body 6, so that the structure is more compact.
The end part of the valve body 6 is provided with two inserting ports 7 communicated with the joint mounting port, the joint 5 is provided with an annular clamping groove 33, two fixing pins 8 respectively extend into the two inserting ports 7, penetrate through the annular clamping groove 33 and are respectively and fixedly connected with the two inserting ports 7, the two fixing pins 8 are respectively in limit fit with the axial direction of the joint 5, and the disassembly and assembly are carried out from the end part of each module 2, so that the joint 5 is simple, convenient and reliable to install, the workload of disassembling and assembling the joint 5 is greatly reduced, and the efficiency is improved.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
