Description
Technical field
The utility model relates to natural gas transport field, relates 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 utility model patent of " CN 202746609 U ", discloses a kind of large-capacity valve for natural gas transport.It comprises valve body, and in valve body mobile valve seat, valve seat formation when central through bore internal surface in valve body contact seals, to stop rock gas to pass through.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.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and can realize gas discharge even regulation, and the multistage flow control valve of rock gas that adjustment process can be strictly controlled.
The purpose of this utility model is achieved through the following technical solutions:
The multistage flow control valve of rock gas, comprises valve body and spool; Valve body comprises inlet end, outlet side and is connected with valve interior surface and the spacer body between inlet end and outlet side, and spacer body comprises horizontal segment, the vertical section being 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 a plurality of inlet holes, inlet hole extends to the bottom of adjusting body; Spool also comprises and is arranged at the location piece that regulating lever 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 over against the top of reference bar, N inlet hole is over against the internal surface of vent from top to bottom, N is the positive integer being more than or equal to.
The utility model is when 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.When 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.When 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 that is positioned at the inlet hole of 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 guarantees to regulate at every turn, and the increasing amount of gas discharge or reduction can both strictly be limited, and location piece is set and with reference to bar.When adjusting gas discharge, each adjustment all makes one of them location piece over against the top of reference bar.So can avoid when Flow-rate adjustment, one of them inlet hole is partly 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.
When 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.
When 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 utility model is that beneficial effect is:
1. the utility model can be realized the even regulation of gas discharge;
2. location piece is set and with reference to bar, avoids when Flow-rate adjustment, one of them inlet hole is partly 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. when 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.
