Description
Technical field
The present invention relates to inlet valve field, particularly the quantitative feeding cycle device of one.
Background technology
As shown in Figure 1, current inlet valve principle of work: when the first air inlet/outlet air inlet, when the second air inlet/outlet is died, needle-valve promotes to the right, and valve port is opened, raw material is from valve port position feed; When the first air inlet/outlet is died, during the second air inlet/outlet air inlet, needle-valve promotes left, and valve port is closed, and valve port stops feed; Regulating valve port gap by turning bolt position to realize, namely regulating feed pressure.
There is following defect in this inlet valve: (1), and due to raw material self reason (wherein having a kind of raw material to be isocyanates), long-time stagnation can cause crystallization, once crystallization, can cause inlet valve and line clogging, and cleaning gets up to bother very much.(2), regulate valve port gap (feed pressure) by bolt, time one length can cause bolt thread stripped thread or loosen, and valve port gap also can loosen, and causes feed pressure unstable.
Summary of the invention
goal of the invention:for problems of the prior art, the invention provides a kind of quantitatively feeding cycle device, can avoid stagnating in valve due to raw material and the crystallization that causes, avoid pipe choking.
technical scheme:the invention provides a kind of quantitatively feeding cycle device, comprise circulation valve, inlet valve, feeding pipeline and circulating line, when described device is in feed state, the inlet valve valve port of described inlet valve is communicated with between described feeding pipeline, closes between the circulation valve valve port of described circulation valve and described circulating line; When described device is in recurrent state, close between described inlet valve valve port and described feeding pipeline, described circulation valve valve port is communicated with between described circulating line.
Further, described circulation valve also comprises circulation valve induction opening, circulation valve air regulation room, circulation valve adjust bar and circulation valve needle-valve, and described inlet valve also comprises inlet valve induction opening, inlet valve air regulation room, inlet valve adjust bar and inlet valve needle-valve; Described circulation valve induction opening is communicated with described circulation valve air regulation room, the afterbody of described circulation valve adjust bar effectively contacts with the first barrier film of described circulation valve air-handling compartment, head is effectively contacted by the afterbody of the second barrier film with described circulation valve needle-valve, and the head of described circulation valve needle-valve blocks described circulation valve valve port; Described inlet valve induction opening is communicated with described inlet valve air regulation room, the afterbody of described inlet valve adjust bar effectively contacts with the 3rd barrier film of described inlet valve air-handling compartment, head is effectively contacted by the afterbody of the 4th barrier film with described inlet valve needle-valve, and the head of described inlet valve needle-valve blocks described inlet valve valve port.
Further, described quantitative feeding cycle device also comprises the first electromagnetic valve and the second electromagnetic valve, and described first electromagnetic valve is communicated with described circulation valve induction opening, and described second electromagnetic valve is communicated with described inlet valve induction opening.Use electromagnetic valve to regulate the air of circulation valve and inlet valve to reconcile the pressure of room, to regulate cycle pressure and feed pressure, compared with being regulated by bolt with prior art, effectively can promote circulation and feed precision.
beneficial effect:feeding device in the present invention, not only can realize feed, can also circulate to the raw material in inlet valve, is stuck in pipeline occurs crystallization, blocking pipe to avoid raw material, effectively promotes the service life of this feeding device.
Accompanying drawing explanation
Fig. 1 is the structural representation of quantitative feeding valve in prior art;
Fig. 2 is the structural representation of quantitative feeding cycle valve in the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
embodiment 1:
A kind of quantitatively feeding cycle device is provided in present embodiment, as shown in Figure 2, primarily of circulation valve 1, inlet valve 2, circulating line 4 and feeding pipeline 3 form, the rear end that circulation valve induction opening 11 in circulation valve 1 and circulation valve air reconcile room 12 is communicated with, the front end that circulation valve air reconciles room 12 is provided with the first barrier film 16, this first barrier film 16 effectively contacts with the afterbody of circulation valve adjust bar 13, effectively contacted by the second barrier film 17 between the head of circulation valve adjust bar 13 and the afterbody of circulation valve needle-valve 14, circulation valve valve port 15 just can be blocked and shut by the head of circulation valve needle-valve 14, the rear end that inlet valve induction opening 21 in inlet valve 2 and inlet valve air reconcile room 22 is communicated with, the front end that inlet valve air reconciles room 22 is provided with the 3rd barrier film 26,3rd barrier film 26 effectively contacts with the afterbody of inlet valve adjust bar 23, effectively contacted by the 4th barrier film 27 between the head of inlet valve adjust bar 23 and the afterbody of inlet valve needle-valve 24, inlet valve valve port 25 just can be blocked and shut by the head of inlet valve needle-valve 24.
Under feed state, air enters circulation valve air regulation room 12 by circulation valve induction opening 11, the left convex promotion circulation valve adjust bar 13 of air compressing first barrier film 16 moves to left, and promotes the second barrier film 17 left convex and then promote circulation valve needle-valve 14 pairs of circulation valve valve ports 15 and close by circulation valve adjust bar 13; What carry out is that inlet valve induction opening 21 stops air inlet simultaneously, and moved to right by inlet valve needle-valve 24 by raw material self flow pressure, inlet valve valve port 25 is opened, and raw material flows in feeding pipeline 3, and flow direction is in figure shown in a and b dotted arrow.
