Description
Technical field
The present invention relates to natural gas transport field, particularly relate to the flow adjusting structure for natural gas transport.
Background technique
The existing valve body for natural gas transport cannot realize the even regulation of gas discharge.
Such as, 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 of movement in valve body, is formed and seals, pass through to stop rock gas when valve seat contacts with the central through bore internal surface in valve body.Valve seat moves up and after the through hole of off center, the fraction area of central through bore exposes, and now rock gas can be flow through by central through bore, and gas discharge is less.Valve seat continues to move up, and the area that exposes of central through bore becomes large size instantaneously from small size, and gas discharge becomes large instantaneously.Therefore, the existing valve body for natural gas transport, because its valve core structure limit, can only realize break-make during natural gas transport, cannot realize the adjustment of gas discharge.
Summary of the invention
Namely object of the present invention is to overcome the deficiencies in the prior art, provide a kind of can the gas discharge regulation structure of even regulation gas discharge.
Object of the present invention is achieved through the following technical solutions:
Gas discharge regulation structure, comprises spool, and spool comprises cylindrical shell, regulating lever and adjustment body, and regulating lever runs through the two ends of cylindrical shell, and adjustment body is connected with the bottom of regulating lever; The periphery of adjustment body evenly offers multiple inlet hole from top to bottom, and inlet hole extends to the bottom of adjustment body.
The present invention is for replacing the spool of the existing Flow valve for natural gas transport.The valve body of the existing Flow valve for natural gas transport comprises inlet end, outlet side and is connected with valve interior surface and spacer body between inlet end and outlet side, the vertical section that spacer body comprises horizontal segment, is connected with horizontal segment two ends, horizontal segment offers vent; The top of valve body offers the spool mounting hole corresponding with vent.
Operationally, cylindrical shell is fixed in spool mounting hole in the present invention, and adjustment body is arranged in vent.The rock gas flowed into from inlet end enters adjustment body by inlet hole, then flows out, finally by outlet side bottom adjustment body.Moving up and down by regulating lever, drives tune to move up and down in overall.When adjusting body and moving upward, the quantity being positioned at the inlet hole above vent becomes many, makes more rock gas can enter adjustment body, and the flow of rock gas increases.When adjusting body and moving downward, the quantity of this inlet hole be positioned at above vent tails off, and the rock gas entering 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 be positioned at above vent, by moving up and down adjustment body, can realize the even regulation of gas discharge.
Further, described spool also comprises the elastic ring be connected with the internal surface of described cylindrical shell, the elastic sleeve be 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, after rock gas enters cylindrical shell, the internal pressure of cylindrical shell increases, under the effect of the pressure, elastic sleeve is pressed on regulating lever, thus avoids rock gas by the gap effusion between elastic sleeve and regulating lever.
Further, described spool also comprises the limited ring be connected with the internal surface of described cylindrical shell, and limited ring contacts with the upper surface of described elastic ring, there is gap between the internal surface of limited ring and the outer surface of described regulating lever.
When inner barrel pressure increase, limited ring can prevent elastic ring from deforming in longitudinal extent, thus avoids because elastic ring distortion causes elastic sleeve cannot be fitted in problem on regulating lever completely.
Further, seal ring B is provided with between described barrel end and described regulating lever.
Seal ring B is set, the rock gas in valve body can be stoped to enter cylindrical shell, avoid the possibility of leaking further.
Further, described regulating lever is provided with scale.
Pass through scale, operator can learn that adjustment body is positioned at the height of vent upper section, the quantity of the inlet hole be positioned at above vent can be drawn again according to the spacing between inlet hole, the flow of now rock gas can be drawn according to the quantity of the inlet hole be positioned at above vent.
In sum, advantage of the present invention and beneficial effect are:
1. the present invention can realize the even regulation of gas discharge;
2. the present invention directly can replace the spool of the existing Flow valve for natural gas transport, applied widely;
3. in cylindrical shell, arrange elastic ring and elastic sleeve, after rock gas enters cylindrical shell, the internal pressure of cylindrical shell increases, and under the effect of the pressure, elastic sleeve is pressed on regulating lever, thus avoids rock gas by the gap effusion between elastic sleeve and regulating lever;
4. when inner barrel pressure increase, limited ring can prevent elastic ring from deforming in longitudinal extent, thus avoids because elastic ring distortion causes elastic sleeve cannot be fitted in problem on regulating lever completely;
5. seal ring B is set, the rock gas in valve body can be stoped to enter cylindrical shell, avoid the possibility of leaking further;
6., by scale, operator can learn and control the flow of rock gas easily, easy to use.
