Description
Technical field
The present invention relates to natural gas transport field, relate in particular to the multistage flow control valve for natural gas transport.
Background technique
The existing valve body for natural gas transport cannot be realized the even regulation of gas discharge.
For example, publication number is the patent of invention of " CN 202746609 U ", discloses a kind of large-capacity valve for natural gas transport.It comprises valve body, and the valve seat moving in valve body, forms sealing, to stop rock gas to pass through when valve seat contacts with the central through bore internal surface in valve body.Valve seat move up and off center through hole after, the fraction area of central through bore exposes, now rock gas can flow through by central through bore, gas discharge is less.Valve seat continues to move up, and the area that exposes of central through bore becomes large size from small size moment, and gas discharge moment becomes large.Therefore, break-make when the existing valve body for natural gas transport can only be realized natural gas transport, cannot realize the adjusting of gas discharge.
Summary of the invention
Object of the present invention is to overcome the deficiencies in the prior art, provides one can realize gas discharge even regulation, and the multipoint positioning natural gas flow adjustable valve that adjustment process can be strictly controlled.
Object of the present invention is achieved through the following technical solutions:
Multipoint positioning natural gas flow adjustable valve, comprises valve body and spool; Valve body comprises inlet end, outlet side and is connected with valve interior surface and spacer body between inlet end and outlet side, and the vertical section that spacer body comprises horizontal segment, is connected with horizontal segment two ends, offers vent on horizontal segment; The top of valve body offers the spool mounting hole corresponding with vent; Spool comprises cylindrical shell, regulating lever and adjustment body, and cylindrical shell is fixed in spool mounting hole, and regulating lever runs through the two ends of cylindrical shell, adjusts body and is connected with the bottom of regulating lever, adjusts body and is arranged in vent, adjusts the outer surface of body and the internal surface of vent and contacts; On the periphery of adjustment body, evenly offer from top to bottom multiple inlet holes, inlet hole extends to the bottom of adjusting body; Spool also comprises the location piece that is arranged at regulating lever and is positioned at cylindrical shell upper section, and location piece is evenly distributed from top to bottom, and the quantity of location piece is identical with the quantity of inlet hole, and the spacing of location piece is identical with the spacing of inlet hole; Spool also comprise be arranged at cylindrical shell top with reference to bar, when N location piece is from top to bottom during just to the top of reference bar, the just internal surface to vent of N inlet hole from top to bottom, N is the positive integer being more than or equal to.
The present invention is in the time of work, and the rock gas flowing into from inlet end enters adjustment body by inlet hole, then flows out from adjusting body bottom, finally passes through outlet side.By moving up and down of regulating lever, drive to adjust to move up and down in overall.In the time that adjustment body moves upward, the quantity that is positioned at the inlet hole of vent top becomes many, makes more rock gas can enter adjustment body, and the flow of rock gas increases.In the time that adjustment body moves downward, this quantity that is positioned at the inlet hole of vent top tails off, and the rock gas that enters adjustment body is tailed off, and the flow of rock gas reduces.The flow of rock gas is directly proportional to the quantity of the inlet hole that is positioned at vent top, by moving up and down adjustment body, can realize the adjusting of gas discharge.The controllability regulating in order to strengthen gas discharge ensures to regulate at every turn, and the increasing amount of gas discharge or reduction can both strictly be limited, and location piece are set and with reference to bar.In the time adjusting gas discharge, each adjustment all makes the just top to reference bar of one of them location piece.So can avoid in the time of Flow-rate adjustment, one of them inlet hole part is positioned at vent, and part is positioned at outside vent, the problem that causes gas discharge accurately to be controlled.
Further, the internal surface of described vent is provided with seal ring A, and the outer surface of described adjustment body contacts with seal ring A.
Seal ring A is set, prevents that rock gas from flowing out by the gap of adjusting between body and vent, rock gas can only be flowed out by adjusting body, thereby improved the controllability of gas discharge.
Further, described spool also comprises the elastic ring being connected with the internal surface of described cylindrical shell, the elastic sleeve being connected with elastic ring internal surface, and elastic sleeve is placed on described regulating lever.
In the time that rock gas occurs to reveal, rock gas enters cylindrical shell, then overflows from cylindrical shell upper end.In order to stop natural gas leaking, elastic ring and elastic sleeve are set in cylindrical shell, when rock gas enters after cylindrical shell, the internal pressure of cylindrical shell increases, under the effect of pressure, elastic sleeve is pressed on regulating lever, thereby avoids rock gas to overflow by the gap between elastic sleeve and regulating lever.
Further, described spool also comprises the limited ring being connected with the internal surface of described cylindrical shell, and limited ring contacts with the upper surface of described elastic ring, between the internal surface of limited ring and the outer surface of described regulating lever, has gap.
In the time that inner barrel pressure increases, limited ring can prevent that elastic ring from deforming in longitudinal extent, thereby avoids causing elastic sleeve cannot be fitted in the problem on regulating lever completely because of elastic ring distortion.
Further, between described cylindrical shell end and described regulating lever, be provided with seal ring B.
Seal ring B is set, can stops the rock gas in valve body to enter cylindrical shell, further avoid the possibility of leaking.
In sum, advantage of the present invention is that beneficial effect is:
1. the present invention can realize the even regulation of gas discharge;
2. location piece is set and with reference to bar, avoids in the time of Flow-rate adjustment, one of them inlet hole part is positioned at vent, and part is positioned at outside vent, and the problem that causes gas discharge accurately to be controlled, makes Flow-rate adjustment process strictly controlled;
3. seal ring A is set, prevents that rock gas from flowing out by the gap of adjusting between body and vent, rock gas can only be flowed out by adjusting body, thereby improved the controllability of gas discharge;
4. elastic ring and elastic sleeve are set in cylindrical shell, and when rock gas enters after cylindrical shell, the internal pressure of cylindrical shell increases, and under the effect of pressure, elastic sleeve is pressed on regulating lever, thereby avoids rock gas to overflow by the gap between elastic sleeve and regulating lever;
5. in the time that inner barrel pressure increases, limited ring can prevent that elastic ring from deforming in longitudinal extent, thereby avoids causing elastic sleeve cannot be fitted in the problem on regulating lever completely because of elastic ring distortion;
6. seal ring B is set, can stops the rock gas in valve body to enter cylindrical shell, further avoid the possibility of leaking.
