the utility model reasonable and compact in structure, easy to use; The volume of valve seat is little, has shortened the distance of measuring pressure passage and sampling passage, can guarantee that winter, well head did not need to adopt under the prerequisite of any measure, realizes oil pressure monitoring, samples and change manometric object; When changing pressure meter, in pipe, overbottom pressure is discharged by sampling passage, safe.
Accompanying drawing explanation
accompanying drawing 1 is looked sectional structure schematic diagram for the master of the utility model most preferred embodiment.
coding in accompanying drawing is respectively: 1 is valve seat, and 2 is valve rod, and 3 is valve gap, and 4 is valve pocket, and 5 is oil recovery import, and 6 is valve plug, and 7 is measuring pressure passage, and 8 is sampling passage, and 9 install port for pressure meter, and 10 is oil recovery sample tap, and 11 is rotary handle.
The specific embodiment
the utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is to be all described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this antifreeze two way seal pressure measurement sample valve comprises valve seat 1, valve rod 2, valve gap 3 and valve plug 6; Middle inside at valve seat 1 has the internal thread hole communicating up and down, in internal thread hole, by screw thread, the valve rod 2 that can move up and down is installed; In the bottom of valve seat 1, have the open slot that Open Side Down, at the openend of open slot, be installed with valve gap 3, between open slot and valve gap 3, form valve pocket 4, there is oil recovery import 5 at valve gap 3 middle parts below valve rod 2; In the lower end of valve rod 2, being fixedly connected with bottom can be by the valve plug 6 of oil recovery import 5 shutoff, and valve plug 6 is positioned at valve pocket 4; On the valve seat 1 above valve pocket 4, have respectively and can make valve pocket 4 and the extraneous measuring pressure passage communicating 7 and sampling passage 8, the lower port of measuring pressure passage 7 is positioned at valve plug 6 upper outer and communicates with valve pocket 4; The sampling lower port of the passage 8 and sealed upper end face of valve plug 6 is corresponding and communicate with valve pocket 4; The upper port of measuring pressure passage 7 is that pressure meter is installed port 9 and is positioned on the outer face, middle part of valve seat 1; The upper port of sampling passage 8 is on oil recovery sample tap 10 outer face, middle part that is positioned at valve seat 1.Valve seat 1 is fixedly mounted on surface choke by threeway level, at pressure meter, setting pressure table on port 9 is installed; The utility model is a kind of tube valve, and volume is little, easy to use; Shortened the distance that port 9 and oil recovery sample tap 10 are installed from surface choke to pressure meter, fluid, under continuous flow regime, is difficult for occurring the situation of frozen block, facilitates monitoring personnel to carry out monitoring record simultaneously, and time saving and energy saving, operating efficiency is high; Function simultaneously that can realize oil pressure monitoring, sample and change table, practical; While changing table, the fluid in valve pocket 4 and measuring pressure passage 7 and overbottom pressure can be discharged outside valve seat 1 by sampling passage 8, safe and reliable.
can according to actual needs, above-mentioned antifreeze two way seal pressure measurement sample valve be made further optimization and/or improvements:
