Abstract
The utility model relates to an internal elevating valve of a plunger, belonging to the plug valve in block valves. The utility model comprises a valve body, a valve cover, a sealing ring, a hole frame, a plunger, a valve rod and a hand wheel, and wherein, the middle and the lower parts of the plunger are cylinder bodies which are provided with two or more holes. When the valve is opened, a medium stream passes through the cylinder bodies at the middle and the lower parts of the plunger to pass through the holes to flow towards an outlet, avoiding that the medium stream erodes a sealing element, avoiding that the plunger abrades the sealing element, enhancing the sealing performance of the valve, and extending the service life of the valve. The utility model is widely applied to pipelines of medium-pressure and low pressure medium streams, and is especially suitable for medium streams with solid particles.
Description
Logical lift valve belongs to the stopcock in the block valve in a kind of plunger.
Existing plunger lift valve, after the unlatching, MEDIA FLOW flows to outlet through the Sealing internal surface, and under the washing away of MEDIA FLOW, Sealing is subject to erosion.When closing, plunger meeting gauge wear Sealing, the degree of wear was bigger when the coaxality of upper and lower seal ring descended.Cause the valve seal decreased performance, shorten working life, if valve is used in the MEDIA FLOW of band solid particle, situation can be more serious.
The purpose of the utility model is to provide a kind of Sealing to be difficult for erosion and wearing and tearing, the novel plunger lift valve that just sealability is better, working life is long.
The utility model adopts in the plunger logical, and promptly MEDIA FLOW is inner and realize above-mentioned purpose without the method for Sealing internal surface through plunger.
Below in conjunction with embodiment shown in the drawings, the technical solution of the utility model is explained in detail.
Accompanying drawing 1 is an embodiment's of the utility model a plan view.Among the figure:
1---handwheel, 2---valve rod,
3---valve gap, 4---plunger,
5---seal ring, 6---the hole,
7---the hole frame, 8---valve body.
Logical lift valve is by valve body (8) in the plunger, be fixed by bolts to the valve gap (3) on the valve body (8), place upper and lower seal ring (5) and hole frame (7) in the valve body (8), be positioned at the plunger (4) of seal ring (5) and hole frame (7), be enclosed within the valve rod (2) at plunger (4) top, the handwheel (1) that is fixed on valve rod (2) top with nut is formed.
In the said plunger (4), the bottom is cylindrical body, the internal diameter of cylindrical shell equals the inside nominal diameter of valve, barrel has two or more holes (6), the shape in hole (6) is square or circular or other geometrical shapies, the inside nominal diameter that the size in hole (6) and quantity depend on valve, the horizontal center line of each hole (6) is positioned on the same horizontal plane.
Plan view when accompanying drawing 1 is the valve complete opening.After MEDIA FLOW enters valve body (8), flow in the plunger (4), in the cylindrical shell of bottom, (6) flow out valve body (8) through the hole again.
Rotation hand wheel (1), plunger (4) descend under the drive of valve rod (2) gradually, and the outlet on the valve body (8) is departed from the hole (6) on plunger (4) cylindrical shell gradually, and flow reduces gradually.When plunger (4) dropped to a certain degree, hole (6) cut off fully with outlet, and valve is in closed condition.
Therefore, no matter valve be in close, part is opened or during the complete opening state, MEDIA FLOW can erosion seal ring (5).In addition, the outer rim of plunger (4) moves at the inner edge of upper and lower seal ring (5) all the time, has avoided the gauge wear phenomenon of the plunger of existing plunger lift valve to Sealing.
Because the utility model has avoided MEDIA FLOW to the wearing and tearing to Sealing of the erosion of Sealing and plunger, thereby has improved the sealability of valve, prolonged the working life of valve, and decreased to the requirement of Sealing is also corresponding.During this valve is widely used in, in the pipeline of low pressure MEDIA FLOW, be specially adapted to have in the MEDIA FLOW of solid particle.
Among the embodiment shown in the drawings, the inside nominal diameter Dg of valve is 25mm, in the plunger (4), have four square holes (6) on the cylindrical body of bottom.
Claims (2)
1, logical lift valve in a kind of plunger, by valve body (8), be fixed on valve gap (3) on the valve body (8), place seal ring (5) and hole frame (7) in the valve body (8), be positioned at the plunger (4) of seal ring (5) and hole frame (7), the valve rod (2) that is enclosed within plunger (4) top, the handwheel (1) that is fixed on valve rod (2) top form, it is characterized in that said plunger (4) in, the bottom is cylindrical body, has hole (6) on the cylindrical body.
2, by the described valve of claim 1, the quantity that it is characterized in that said hole (6) depends on the inside nominal diameter of valve, and the horizontal center line of each hole (6) is positioned on the same horizontal plane.
