Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Embodiment
For making that structure characteristic of the present utility model and effect of reaching are had and further understand and be familiar with, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, a kind of bidirectional throttling valve, comprise valve body 1 and be sleeved on the adjustment sleeve 2 in this valve body 1 outside, valve body 1 is provided with dividing plate 3, be respectively equipped with mutual opposed feed pathway 4 and liquid outlet channel 5 at the two ends of this dividing plate 3, the both sides that are positioned at dividing plate 3 on the outer wall of valve body 1 are respectively equipped with lead channel 6 and liquid outlet groove 7, lead channel 6 is positioned at the outside of feed pathway 4 and is communicated with feed pathway 4 by the first sets of vias 8, liquid outlet groove 7 is positioned at the outside of liquid outlet channel 5 and is communicated with liquid outlet channel 5 by the second sets of vias 9, as improvement of the present utility model, the inwall of adjustment sleeve 2 is provided with the throttling groove 10 corresponding with lead channel 6 and liquid outlet groove 7, one side of feed pathway 4 is provided with the first pressure detection structure, and a side of liquid outlet channel 5 is provided with the second pressure detection structure.
In the utility model, adjustment sleeve 2 is threaded with valve body 1, and the throttling groove 10 on adjustment sleeve 2 forms feed liquor throttling passage 11 with lead channel 6, and throttling groove 10 forms fluid throttling passage 12 with liquid outlet groove 7.
