Description of drawings

Fig. 1 is the structural representation of existing vacuum filtration valve;

The cutting fluid vacsorb filter apparatus configuration sketch map that Fig. 2 provides for the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is made detailed explanation.

As shown in Figure 2; The vacuum filtration valve that the utility model provides comprises valve body 1 and is arranged on filter core 2 and first, second pneumatic operated

valve

3,4 in the valve body 1 and is used to control the solenoid electric valve 5 of first, second pneumatic operated

valve

3,4 switches; In the present embodiment, what solenoid electric valve adopted is the two-position five-way solenoid directional control valve.

Valve body 1 comprises top cylinder 101 and doffing 102; Top cylinder 101 connects as one through middle contiguous block 103 with doffing 102, and the inner chamber of top cylinder 101 forms upper chamber, and the inner chamber of doffing 102 forms lower chambers; Uncovered of the upper end of top cylinder 101 is by last contiguous block 104 sealings; Uncovered of the bottom of doffing 102 is respectively equipped with vacuum orifice 107 and is separated with liquid sucting port 106 and through filter core 2 by lower connecting block 105 sealings on the last contiguous block 104, the bottom surface of lower connecting block 105 is provided with leakage fluid dram 108.

First pneumatic operated valve 3 is arranged on the middle contiguous block 103; Second pneumatic operated valve 4 is arranged on the lower connecting block 105; Be respectively equipped with first, second air inlet 109,110 that is used to control first, second pneumatic operated

valve

3,4 on middle contiguous block 103 and the lower connecting block 105, first, second air inlet 109,110 is connected respectively to two-position five-way solenoid directional control valve 5.

First pneumatic operated valve 3 is open in usual, and second pneumatic operated valve 4 is a normally closed type, and two-position five-way solenoid directional control valve 5 is in first operating position, and upper and lower chamber is communicated with, and the cutting fluid that is drawn in the upper chamber by vacuum cup 7 can flow into lower chambers through first pneumatic operated valve 3; When two-position five-way solenoid directional control valve 5 was in second operating position, first pneumatic operated valve 3 cut out under the effect of pressed gas, and second pneumatic operated valve 4 is opened, so the cutting fluid of bottom chamber is discharged through leakage fluid dram 108.

In order to accelerate the drain age velocity of lower chambers; Also be provided with the air inlet pipe 111 that communicates with lower chambers in the middle contiguous block 103, air inlet pipe 111 is communicated with first air inlet 109, like this; When two-position five-way solenoid directional control valve 5 is in second operating position; First pneumatic operated valve 3 cuts out under the effect of pressed gas, and pressed gas gets into bottom chamber via first air inlet 109 and air inlet pipe 111 simultaneously, thereby has accelerated the velocity of discharge of cutting fluid.

Again referring to Fig. 2; The cutting fluid vacsorb filter that the utility model provides comprises vacuum filtration valve and the vacuum generating device 6 and vacuum cup 7 of said structure; Vacuum generating device 6 is connected on the vacuum orifice 107 of vacuum filtration valve; Vacuum cup 7 is connected on the liquid sucting port 106 of vacuum filtration valve; Vacuum generating device 6 makes through Compressed Gas in the inner chamber of vacuum filtration valve and produces vacuum, so blot fast through the cutting fluid of vacuum cup 7 with the part to be processed surface, will add filtrations such as the iron filings that stay man-hour, aluminium powder, waste residue simultaneously.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
