Background technique
In the pcb board production process, need in the pcb board making equipment, inject various liquid by flexible pipe, as electroplate liquid, etching solution or the like, in the prior art, above-mentioned flexible pipe is controlled opening and closing by solenoid valve, closes flexible pipe after the solenoid valve energising, opens flexible pipe after the solenoid valve outage.
But adopt solenoid valve to control the opening and closing of flexible pipe, it has following shortcoming:
(1) solenoid valve failure rate height after solenoid valve produces fault, can not normally be closed flexible pipe after the solenoid valve outage, and liquid is appointed so can be influenced the ordinary production of pcb board, even cause pcb board to be scrapped by in the flexible pipe access arrangement;
(2) the anti-strong acid-base corrosion ability of solenoid valve is poor, and pcb board is generally all made under the strong acid-base environment, and therefore, solenoid valve often is subjected to the strong acid-base corrosion and damages;
(3) solenoid valve is an electric device, and potential safety hazard is arranged, and can not be used for the higher environment of temperature, and the temperature of pcb board production environment is generally all higher, causes the potential safety hazard of solenoid valve more;
(4) in use, foreign material are easily advanced in the gap of solenoid valve, cause solenoid valve to produce fault and may burn.
The model utility content
Technical problem to be solved in the utility model is to provide low, anticorrosive, no potential safety hazard of a kind of rate of fault and the effective pneumatic on-off valve that opens and closes of controlling liquid flexible pipe.
The utility model is to realize like this, a kind of pneumatic on-off valve, be used to control the opening and closing of the liquid hose of pcb board making equipment, this pneumatic on-off valve comprises valve body and the valve head of fixedlying connected with described valve body, described flexible pipe is arranged on the described valve head, is provided with the pneumatic mechanism that can open and close described flexible pipe in the cavity that described valve body and valve head form.
Particularly, described pneumatic mechanism comprises and is fixedly arranged on the squeeze head in the described valve head and is slidedly arranged on piston in the described valve body, described piston is connected with jacking block by guide rod, and described jacking block is slidedly arranged in the described valve head, and described flexible pipe is located between described squeeze head and the jacking block; Described pneumatic mechanism also comprises first gas port that is opened in described valve body top and second gas port that is opened in described valve body lower portion.
More specifically, described first gas port and second gas port are connected to external solenoid valve by first tracheae and second tracheae respectively, and described solenoid valve is connected with air compressor.
More specifically, described flexible pipe is the rubber material.
More specifically, the cross section of described squeeze head is inverted cone.
More specifically, the top of described jacking block is the plane.
Compared with prior art, the utility model adopts pneumatic mechanism to open and close flexible pipe, and reliable, rate of fault is low, has guaranteed the normal opening and closing of flexible pipe; Because pneumatic mechanism is a mechanical structure, antiacid caustic corrosion ability is strong, and pneumatic mechanism can not be subjected to acid and alkali corrosion and damage; In addition, because pneumatic mechanism is non-electric device, can not produce potential safety hazard.
Description of drawings
Fig. 1 is the sectional view of the pneumatic on-off valve that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, a kind of pneumatic on-off valve 1 that the utility model embodiment provides, be used to control the opening and closing of the liquid hose 2 of pcb board making equipment, this pneumatic on-off valve 1 comprises valve body 11 and the valve head 12 of fixedlying connected with described valve body 11, described flexible pipe 2 is arranged on the described valve head 12, is provided with the pneumatic mechanism 13 that can open and close flexible pipe 2 in the cavity that described valve body 11 and valve head 12 form.Compared with prior art, the utility model adopts pneumatic mechanism 13 to open and close flexible pipe 2, and reliable, rate of fault is low, has guaranteed the normal opening and closing of flexible pipe 2; Because pneumatic mechanism 13 is a mechanical structure, antiacid caustic corrosion ability is strong, and pneumatic mechanism 13 can not be subjected to acid and alkali corrosion and damage; In addition, because pneumatic mechanism 13 is non-electric device, can not produce potential safety hazard.
Particularly, described pneumatic mechanism 13 comprises and is fixedly arranged on the squeeze head 131 in the described valve head 12 and is slidedly arranged on piston 132 in the described valve body 11, described piston 132 is connected with jacking block 134 by guide rod 133, described jacking block 134 is slidedly arranged in the described valve head 12, and described flexible pipe 2 is located between described squeeze head 131 and the jacking block 134.Jacking block 134 in uphill process, squeeze head 131 and jacking block 134 squeezing tubes 2, thus realize closing the purpose of flexible pipe 2; Jacking block 134 is in the decline process, and jacking block 134 unclamps flexible pipe 2, thereby realizes opening the purpose of flexible pipe 2.
Described pneumatic mechanism 13 also comprises first gas port 135 that is opened in described valve body 11 tops and second gas port 136 that is opened in described valve body 11 bottoms, described first gas port 135 and second gas port 136 are connected to an external solenoid valve 3 by first tracheae 137 and second tracheae 138 respectively, and described solenoid valve 3 is connected with air compressor 4.The gas delivery that described air compressor 4 produces is to solenoid valve 3, solenoid valve 3 selects to connect first tracheae 137 or second tracheae 138 according to the motion state of pneumatic mechanism 13, be specially: when piston 132 need move upward when closing flexible pipe 2, solenoid valve 3 connects second tracheae 138 automatically and cuts out first tracheae 137, pressurized gas enters in the valve body 11 by second tracheae 138, compressed air-driven piston 132 moves upward, when moving to the summit, jacking block 134 squeezing tubes 2 that are connected with piston 132, and the opposite side of flexible pipe 2 is by squeeze head 131 extruding, flexible pipe 2 is closed with regard to being easy to be squeezed flat, thereby liquid flows in the prevention flexible pipe 2; When piston 132 need move downward when opening flexible pipe 2, solenoid valve 3 connects first tracheae 137 automatically and cuts out second tracheae 138, pressurized gas enters in the valve body 11 by first tracheae 137, compressed air-driven piston 132 moves downward, make the jacking block 134 that is connected with piston 132 unclamp flexible pipe 2, because flexible pipe 2 is the rubber material, not only corrosion-resistant but also good elasticity arranged, therefore flexible pipe 2 restores to the original state and conducting under the effect of himself elastic force, and liquid can flow in the pcb board making equipment smoothly by flexible pipe 2.
Particularly, the cross section of described squeeze head 131 is inverted cone, the top of described jacking block 134 is the plane, like this, and when jacking block 134 makes progress squeezing tube 2, jacking block 134 is evenly exerted pressure to flexible pipe 2, simultaneously, the pointed end squeezing tube 2 of squeeze head 131, like this, flexible pipe 2 is crushed very soon and closes under the force action of jacking block 134 and squeeze head 131.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
