Description
Technical field
The utility model relates to natural gas transport field, relates in particular to the baffle-type gas discharge regulation structure 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 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, the existing valve body for natural gas transport, because its valve core structure is limit, the break-make can only realize natural gas transport time, 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, provides one can realize gas discharge even regulation, adjustment process can be strictly controlled and can replace existing Flow valve spool baffle-type gas discharge regulation structure.
The purpose of this utility model is achieved through the following technical solutions:
Baffle-type 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, adjusts body and is connected with the bottom of regulating lever; 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 baffle plate that is arranged at regulating lever and is positioned at cylindrical shell upper section, it is isosceles trapezoid that the thickness of baffle plate reduces gradually to make the longitudinal cross-section of baffle plate in the direction away from regulating lever, baffle plate is equidistantly arranged from top to bottom, the quantity of baffle plate is more one than the quantity of inlet hole, and the maximum ga(u)ge of baffle plate equates with the spacing of inlet hole; Spool also comprises the positioning body that is arranged at cylindrical shell top, on positioning body, offer horizontal hole, in horizontal hole, be provided with spring and positioning block, one end of spring is connected with the bottom of horizontal hole, the other end of spring is connected with positioning block, positioning block is measure-alike near the gap between size and adjacent two baffle plates of regulating lever one end, and positioning block embeds in the gap between adjacent two baffle plates under the effect of spring.
The utility model 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, offers vent on horizontal segment; The top of valve body offers the spool mounting hole corresponding with vent.
The utility model is in the time of work, and cylindrical shell is fixed in spool mounting hole, adjusts body and is arranged in vent.Adjust the mounting point of cylindrical shell, make when positioning block embedding is from top to bottom when N gap, 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 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 baffle plate, positioning body, spring and positioning block are set.When adjusting, positioning block is ejected the gap between baffle plate by baffle plate, and spring is compressed; Regulating lever continues mobile, and positioning block, under the effect of spring, embeds in adjacent gap, is now positioned at one of the inlet hole increase of vent top or reduces one, so can realize the even regulation of gas discharge.Meanwhile, this structure also can be avoided in the time of Flow-rate adjustment, and 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.Whether, in adjustment process, vibration and sound that positioning block produces while embedding the gap between baffle plate, can provide clear and definite feedback for staff, be convenient to the adjusting of learning that staff can be clear and definite and put in place.
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 utility model is that beneficial effect is:
