Abstract
The utility model discloses a butterfly plate type ellipsoid valve comprising a valve seat, a valve plate, a valve rod and an operation mechanism, wherein the valve seat and the valve plate are arranged in a valve body, and the valve rod drives the valve plate to be opened and closed. The valve plate is of an ellipsoid plate structure. The valve body is formed by connecting a water inlet section and a water outlet section through a flange seal. The port, located beside the valve board, of the water inlet section is of a bowl-mouth structure expanding in the radial direction to form a slag blocking chamber. The port, located beside the valve board, of the water outlet section is of a cone-mouth structure retracting in the radial direction to form a slag flushing chamber. The valve seat is of a convex ring structure with a cutting edge. The valve seat of the convex ring structure is formed by joining one semi-circular body fixedly connected into the slag blocking chamber and the other semi-circular body fixedly connected into the slag flushing chamber. One half of the valve plate is located in the slag blocking chamber and the other half of the valve plate is located in the slag flushing chamber with the axis of the valve rod as a center. The sealed face of the valve seat and the valve plate is a slope. The butterfly plate type ellipsoid valve has the advantages that when solid particulate matter is deposited in the valve body, the solid particulate matter can be blown away from the valve plate due to the fact that the pressure difference of the two sides of the valve plate is large, and due to the self-cleaning function, the valve is closed tightly and prevented from leakage.
Description
Technical field
The utility model relates to the valve on water pipeline, especially relates to the butterfly plate formula ellipsoid valve being suitable on sediment charge and the relatively many hydraulic pipes of granule foreign.
Background technique
Daily life bathing, industry are for valve in a large number all such as, drainage pipe, municipal engineering confession, sewerage system.Due to sedimentary existence in pipeline, the valves such as now widely used ball valve, gate valve, butterfly valve usually run into the problem that cannot close pipeline when repair and maintenance completely.Especially municipal pipeline engineering, system is large, pipeline is long; Due to burst accident, pipeline cannot be closed, and a large amount of fluid (tap water, heat supply) in water system is bled off in vain, causes the great wasting of resources and loss; If bring the deuce to pay and difficulty also can in the winter time staff's maintenance.
Summary of the invention
It is a kind of simple in structure that the utility model object is to provide, and closes reliable sealing butterfly plate formula ellipsoid valve.
For achieving the above object, the utility model is taked following technical proposals:
Butterfly plate formula ellipsoid valve described in the utility model, comprises valve body, is arranged on valve seat and valve plate in described valve body, and the valve rod and the operating device that drive described valve plate open and close; Described valve plate is ellipse structure, and described valve body is formed by connecting by flange seal by inlet segment and water exit end; The rim of a bowl structure that the port that described inlet segment is positioned at valve plate side is radially expansion is to form pushing off the slag chamber; The port that described water exit end is positioned at valve plate side is for the cone mouth structure of radially shrinking is to form flushing cinder chamber; Described valve seat is the bulge loop structure with cutting edge, and the valve seat of described bulge loop structure forms by being fixed on the indoor hemizonid of pushing off the slag and being fixed on second half indoor ring body linking of flushing cinder; Centered by the axis of described valve rod, half is positioned at indoor second half of pushing off the slag to be positioned at flushing cinder indoor described valve plate; Valve seat is inclined-plane with the sealing surface that valve plate seals mutually.
The utility model advantage major embodiment is in the following areas:
1, structurally, in solid particulate matter is deposited on valve body, is opening or closing the initial stage, due to there is larger pressure difference in valve plate both sides can be the solid matter valve plate that blows off; It guarantees that from cleaning function valve closes tight, does not reveal.
2, valve body area of passage is greater than the pipe joint area of same nominal diameter, so the relative velocity at valve plate place is low, and resistance is little.
3, valve seat is the bulge loop structure with cutting edge, and due to its " knife edge " effect, particulate matter is not easy to stop up and makes valve closing not tight.
4, the utility model is simple in structure, and processing is relatively easy, and Inspection and maintenance is convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model full open state.
Fig. 2 is the structural representation of the utility model closed condition.
Fig. 3 is the just structural representation of opening state of the utility model.
Embodiment
As Figure 1-3, butterfly plate formula ellipsoid valve described in the utility model, comprises valve body, is arranged on valve seat and valve plate 1 in described valve body, and the valve rod 2 and the operating device that drive described valve plate 1 open and close; Described valve plate 1 is ellipse structure, and described valve body is tightly connected and is formed by flange 5 by inlet segment 3 and water exit end 4; The rim of a bowl structure that the port that described inlet segment 3 is positioned at valve plate 1 side is radially expansion is to form pushing off the slag chamber 6; The port that described water exit end 4 is positioned at valve plate 1 side is for the cone mouth structure of radially shrinking is to form flushing cinder chamber 7; Described valve seat is the bulge loop structure with cutting edge, and the valve seat of described bulge loop structure is formed by second half ring body 9 linkings that are fixed on the hemizonid 8 in pushing off the slag chamber 6 and be fixed in flushing cinder chamber 7; Centered by the axis of described valve rod 2, half is positioned at pushing off the slag chamber 6 second half is positioned at flushing cinder chamber 7 described valve plate 1; Valve seat is inclined-plane with the sealing surface that valve plate 1 seals mutually.
The utility model working principle is summarized as follows:
1, valve wide open opens state
As shown in Figure 1, valve is at full open state, by valve rod 2, make oval valve plate 1 rotate the state to Fig. 1, fluid enters in valve body pushing off the slag chamber 6 from valve inleting water section 3, and valve body is ellipsoid shape, area of passage is greater than the pipe joint area of same nominal diameter, valve plate 1 place's relative velocity is low, and resistance is little, is convenient to foreign material and discharges.When fluid is during through valve seat cutting edge, the foreign material that wherein particle is larger are blocked, and can not be deposited in valve seat land side and affect sealing, and last fluid is flowed out by water exit end 4.
2, valve full closing state
As shown in Figure 2, valve is at full closing state, and oval valve plate 1 edge and valve seat cutting edge are combined closely, complete throttle down, and the pipeline that makes valve body water exit end 4 one end is in without fluid circulation status.
3, the first opening state of valve
As shown in Figure 3, in valve opening A-stage, by valve rod 2, make oval valve plate 1 rotate the state to Fig. 3.Fluid flows into pushing off the slag chamber 6 through inlet segment 3, through oval valve plate 1, flows in flushing cinder chamber 7, then by water exit end 4, is flowed out.Under this state, oval valve plate 1 two ends rate of flow of fluid is different and have a larger pressure difference, therefore the solid matter valve plate 1 that blows off can be reached from cleaning function, is convenient to the sealing of valve.
