5. Backstop depth adjustable range: 0-150mm, maximum PCB board cutting width: 150mm, maximum PCB board cutting length: 400mm
6. Thickness: 0.2-3.2mm, maximum thickness between V-slots: 0.25-2.0mm
7. Connecting multiple pieces of PCB board in the solder, folding often hurt the line, or will be broken electronic parts, the use of the board splitter can avoid damage, and can improve efficiency and quality.
8. With the walking knife type board splitting machine to divide, can completely reduce the stress, to prevent the cracking of solder joints and parts breakage.
9. Using the upper circular knife under the flat knife method, PCB board to the board splitting machine under the flat knife, switch a step, the upper circular knife moving across to the set point, the PCB board will be cut off and divided, cut off without stripping, the cut is flat.
10. Slitter knife travel can be set at will with the length of the PCB board forward stopping fixed point, stopping fixed point for 0-100-200-300-400mm.
11. Cutter back with cut-off length stopper, according to the different width of the PCB board to do the adjustment, for no V-CUT slot PCB board can also easily cut the board, accurate not oblique cut.
12. Can fine-tune the thickness of various PCB boards, to solve the problem of PCB board V-CUT slot depth.
Multi-function pump self-flow control valve technology
This standard applies to the nominal pressure PN1.0MPa-PN4.0MPa, nominal diameter of DN50mm-DN1200mm multi-function pump control valve. Now the standard technical requirements are described below: 1 Pressure - temperature level Multi-function pump control valve pressure - temperature level by the shell, inner parts and control pipe system material pressure - temperature level to determine. The maximum allowable working pressure of multi-functional pump control valve at a certain temperature takes the small value of the maximum allowable working pressure value of shell, inner part and control pipe system material at this temperature. 1.1 iron shell pressure - temperature level should be consistent with the provisions of GB / T17241.7. 1.2 The pressure of steel shell - temperature level should be consistent with the provisions of GB / T9124. 1.3 For GB / T17241.7, GB / T9124 not specified pressure - temperature grade materials, according to the relevant standards or design requirements. 2, the valve body 2.1 flange flange body should be molded with the valve body as a whole. Iron flange type and size should be consistent with the provisions of GB / T17241.6, the technical conditions should be consistent with the provisions of GB / T17241.7; steel flange type and size should be consistent with the provisions of GB / T9113.1, the technical conditions Should comply with the provisions of GB / T9124. 2.2 Body structure length. 2.3 The minimum wall thickness of the valve body Castings minimum wall thickness of the valve body should be consistent with the provisions of Table 3 GB / T13932-1992, the minimum thickness of steel castings body valve should be consistent with the provisions of Table 1 of JB / T8937-1999. 3 valve cover seat 3.1 valve cover and diaphragm seat, diaphragm seat and valve body connection type should be flanged. 3.2 The number of patch and valve body connection bolts shall not be less than four. 3.3 valve cover and diaphragm seat minimum wall thickness by 2.3 requirements. 3.4 bonnet and diaphragm seat flange should be round. Flange sealing surface type can be flat, convex or concave type. 4 stem, slow closing valve plate, the main valve plate 4.1 slow closing valve plate and stem should be connected and secure. 4.2 slow closing valve plate and the main valve plate sealing type should be sealed metal type. 4.3 The main valve plate and stem must slide flexible and reliable. 4.4 The main valve plate and the main valve plate seal can be sealed metal and non-metallic two types of seals. 5 Diaphragm 5.1 Diaphragm performance shall comply with the requirements of Table 2 (see next page). 5.2 appearance quality of the diaphragm should be consistent with the provisions of HG / T3090. 5.3 When applied to drinking water, the diaphragm material safety should be consistent with the provisions of GB / T17219. 6 control pipe system control pipe system components should be able to withstand the maximum working pressure of the valve, all parts shall not leak. 7 Materials 7.1 The selection of the main components and parts should be according to the provisions of JB / T5300. 7.2 copper alloy castings shall comply with the provisions of GB / T12225; gray cast iron castings shall comply with the provisions of GB / T12226, the tensile strength of not less than 200MPa; ductile iron castings shall comply with the provisions of GB / T12227; carbon steel castings shall comply with GB / T12229 provisions; austenitic steel castings should be consistent with the provisions of GB / T12230. 7.3 Steel multi-function pump control valve casting appearance quality should be consistent with the provisions of JB / T7927, iron multi-function pump control valve casting appearance quality reference JB / T7927's. 8 shell strength Multifunctional pump control valve shell strength should be consistent with the provisions of GB / T13927. Sealing performance 9 Multifunctional pump control valve sealing performance should be consistent with the provisions of GB / T13927. 10 Cleanliness Multipurpose pump control valve cleanliness should be consistent with the provisions of JB / T7748. 11 Painting When applied to drinking water, multifunctional pump control valve cavity coating material safety should be consistent with the provisions of GB / T17219. Painting the outer surface is not specified, special requirements specified in the order contract. More Keyword Search: Pumps, Control Valves
