Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of sequence control valve of this utility model；
Fig. 2 is the valve body structure schematic diagram of a kind of sequence control valve of this utility model.
Detailed description of the invention
As shown in Figure 1-2, this utility model one sequence control valve, including: valve body 11, inlet seal part 5, ball sealer 4, conductive bar 3 and stage clip cap 21.Valve body 11 includes valve pocket 12 and the air inlet 13, venthole 14 and the adjustment hole 15 that are connected respectively with valve pocket 12；Wherein air inlet 13 setting coaxial with adjustment hole 15.Stage clip cap 21 is arranged at the top of valve body 11；Spring top cap 22, stage clip 23 and pole cap 24 it is disposed with from top to bottom in stage clip cap 21 inner chamber；Have through hole in the two ends up and down of stage clip cap 21, wherein go up through hole screwed regulation bolt 25 for regulating stage clip elastic force, lower through-hole is coaxially disposed with the adjustment hole 15 of valve body 11.Conductive bar 3 slidable fit in adjustment hole 15, and conductive bar 3 top stretch into the through hole of stage clip cap 21 bottom after contact with pole cap 24 stress, the bottom of conductive bar 3 is positioned at valve pocket 12.Inlet seal part 5 is arranged at the air inlet 13 of valve body 11, concrete can screw mode connect to use；Vertical through holes 51 is had on inlet seal part 5.Ball sealer 4 is installed between conductive bar bottom and vertical through holes 51, does not wherein misplace in order to ensure ball sealer 4, and the bottom of conductive bar 3, the top of inlet seal part 5 are disposed as arc groove, and ball sealer 4 is installed in this at two at arc groove.
Further, the connection of this utility model and miscellaneous equipment for convenience, this utility model at the air inlet, venthole of valve body respectively car have female thread.
Further, for the assembling of product and easy to maintenance, being detachable installation between stage clip cap and valve body, specifically structure is: be provided with a screw 16 in the top of valve body, and screw 16 is coaxially disposed with adjustment hole 15；Stage clip cap 21 and screw 16 screw combination.
Further, in order to ensure the seal between inlet seal part 5 and air inlet 13, this utility model is provided with sealing ring 52 in the junction of inlet seal part 5 and valve body air inlet 13.
The operation principle of a kind of sequence control valve of this utility model is:
The air inlet of valve body is connected with high-pressure air source；The venthole of valve body is connected with demand end；The gases at high pressure of air inlet position give one thrust upwards of ball sealer all the time；
1. when gases at high pressure are more than the elastic force of stage clip to the thrust of ball sealer, then ball sealer moves up (now conductive bar moves up, and stage clip compresses), and ball sealer departs from inlet seal part, thus the air inlet of valve body is connected with venthole.
2. when gases at high pressure are less than the elastic force of stage clip to the thrust of ball sealer, then ball sealer transfixion, seal and ask the vertical through holes blocking of inlet seal part, thus the air inlet of valve body is not communicated with venthole.
Embodiment described above is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims determine.
