The valve rod penetrates through a valve cover and is connected with a valve clack inside the valve cavity. The valve clack is fixed to an opening formed by two partition pieces in the valve cavity. The upper portion of the valve cover is connected with a pressing cap and the lower portion of the valve cover is connected with the valve body. The valve clack comprises a valve clack body, a valve core and a closed ring. The lower portion of the valve core is arranged in the valve clack body, and the closed ring is arranged at the lower end of the valve clack body. A water outlet is formed in the valve clack body. The screw cap position on the valve clack body is provided with sealing rings. A fixing column is arranged above the valve core, the outer surface of the fixing column is provided with a seamed edge. Three sealing rings are correspondingly arranged in a sealing groove close to the middle of the valve core. The lower portion of the valve core is provided with a rotating support leg, the rotating support leg is connected with an arc-shaped section, a water inlet section is arranged below the arc-shaped section, and the two ends of the water inlet section are provided with convex edges which are correspondingly arranged in a groove in the inner wall on the lower portion of the valve clack body. According to the quick-opening stop valve, the arc-shaped section is controlled to rotate through the hand wheel, quick opening or closing of the valve by 90 degrees is achieved, and the valve is more flexible in opening and closing of the valve, better in sealing performance and longer in service life.
Description
Technical field
The utility model relates to a kind of valve, relate in particular to a kind of can left and right open open soon stop valve, belong to valve technology field.
Background technique
Stop valve, is also pipe valve, is one of most popular a kind of valve, and why very popular it is, be due in switching process between sealing surface frictional force little, more durable, Lift is little, easy to manufacture, easy to maintenance, be not only applicable to mesolow, and be applicable to high pressure.
Stop valve can be divided into straight-through stop valve, Oblique Stop Valve, Angle Stop valves and plunger stop valve by channel direction.
The open-shut device of stop valve is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of valve seat, and the forms of motion of valve rod refers to the valve that flap moves along valve seat center line, and flap blocks up on the opening of two partitions formation on valve pocket.
The break-make of stop valve realizes by the mobile of flap, and in actual use, flap may with valve pocket in partition block or block-up position has deviation, thereby make flap and valve pocket is poorly sealed causes leakage.Existing stop valve is long-term mobile in addition easily causes plunger partly to wear and tear, and causes the damage of equipment, while operating simultaneously, need several circles of rotary handle even more multi-turn just understand Open valve, switch valve comparatively bothers.
Summary of the invention
In order to solve problems of the prior art and deficiency, the utility model provides a kind of stop valve of opening soon, by the redesign to flap, no longer moving along valve seat center line of flap, controls the rotation of arc lobe by handwheel, realize the left and right of valve and open the unlatching that 90 degree can be realized valve, switch is more flexible, and wear resistance is better, better tightness, can not reveal, extend the working life of valve.
The purpose of this utility model is to realize by following technological scheme
Open soon stop valve, comprise handwheel, valve rod, valve gap, valve body, flap in structure, handwheel connects valve rod, is formed with valve pocket in valve body, and valve rod is connected with flap in valve pocket through valve gap, and flap is fixed in the opening of two partition formation in valve pocket.
Described valve gap, is connected with pressure cap on it, be provided with trim ring and seal ring in pressure cap, under valve gap, connects valve body.
Described valve body, has two partitions in it, valve pocket internal channel direction has straight-through type, direct current type or right-angle type.
Described flap, comprise valve petal body, spool, airtight circle, spool lower device is in valve petal body, airtight coil apparatus is in valve petal body lower end, on valve petal body, have water outlet, valve petal body upper cap nut place is provided with seal ring, there is a fixing column spool top, fixing column outer surface has seamed edge, and in the seal groove of spool near middle, correspondence is provided with three seals circle, and spool bottom is swing leg, swing leg connects arc lobe, arc lobe below is the lobe of intaking, and there is fin at water inlet lobe two ends, and fin correspondence is arranged in the groove in valve petal body lower inner wall.
Described arc lobe, it is whole like Bow, and on it, one side has symmetrical fixed groove, and another side is plane, and the limit of fixed groove both sides on arc lobe is arc-shaped side, forms arc opening.
Described water inlet lobe, correspondingly with arc opening on it is provided with two water intakes.
Described arc lobe and water inlet lobe, adopt the high-abrasive materials such as silicon carbide to make, and wear resistance is better.
During use, flap is connected with valve rod, and flap is pressed and fixed in the opening in valve pocket, by anticlockwise or right rotation handwheel, realize 90 degree rotations of arc lobe, get final product the break-make of control valve.
The utility model has changed motion mode and the structure of traditional stop valve, flap no longer moves along valve gap center line, by handwheel, control the rotation of arc lobe, realize the quick break-make of valve, switch is more flexible, wear resistance is better, there will not be and reveals the problem losing efficacy, and has greatly extended the working life of valve.
