Adopt a long service life's of above-mentioned structure soft sealing valve, rubber valve plate bottom is provided with the cross-section and forms two sealed faces for trapezoidal recess, has improved the leakproofness, sets up arc manger plate simultaneously and follows, plays certain fixed action to the rubber valve plate, avoids taking place deformation when the impact force of medium to rubber valve plate bottom is great under the closed condition, causes the rubber valve plate to damage, has improved the life-span of valve greatly, avoids the dead angle to deposit simultaneously dirty.
Description
Technical Field
The utility model belongs to the technical field of the valve and specifically relates to a long service life's soft sealing valve is related to.
Background
The gate valve controls the conduction or stop of fluid in a pipeline by opening and closing the flashboard, the movement direction of the flashboard is perpendicular to the fluid direction, and when the flashboard is opened and closed, the valve rod moves up and down by rotating the hand wheel. The existing valve plate is divided into soft sealing and hard sealing, the interior of the valve body is kept smooth in order to improve the sealing performance of the existing soft sealing, and under the closing state, the valve plate of the soft sealing is deformed under the thrust of a medium in a pipe due to the fact that a supporting mechanism is not arranged in the valve body, so that the sealing is unreliable, and the service life of the valve is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a long service life's soft sealing valve, rubber valve plate bottom is provided with the cross-section and forms two sealed faces for trapezoidal recess, has improved the leakproofness, sets up arc manger plate simultaneously and follows, plays certain fixed action to the rubber valve plate, avoids taking place deformation when the impact force of medium to rubber valve plate bottom is great under the closed condition, causes the rubber valve plate to damage, has improved the life-span of valve greatly, avoids the dead angle to deposit simultaneously dirty.
In order to realize the above-mentioned purpose, the utility model provides a long service life's soft sealing valve, including valve body, valve gap and set up in this internal valve rod of valve, the valve rod bottom is provided with the rubber valve board, rubber valve board bottom is provided with the cross-section and forms two sealed faces for trapezoidal recess, the valve body with the position that the recess is relative is provided with arc manger plate edge, arc manger plate is trapezoidal along the cross-section.
Preferably, the rubber valve plate both sides are provided with the guide block, this internal guide slide that is provided with of valve.
Preferably, the top of the rubber valve plate is embedded with a connecting threaded sleeve made of metal, and the valve rod is in threaded connection with the connecting threaded sleeve.
Preferably, the arc-shaped water retaining edge is 2mm high.
Therefore, the utility model adopts the above structure a long service life's soft sealing valve, rubber valve plate bottom is provided with the cross-section and forms two sealed faces for trapezoidal recess, has improved the leakproofness, sets up arc manger plate simultaneously and follows, plays certain fixed action to the rubber valve plate, avoids taking place deformation when the impact force of medium to rubber valve plate bottom is great under the closed condition, causes the rubber valve plate to damage, has improved the life-span of valve greatly, avoids the dead angle to deposit simultaneously dirty.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

1. A valve body; 11. a guide slide way; 2. a valve cover; 3. a valve stem; 4. a rubber valve plate; 41. a sealing surface; 5. an arc-shaped water retaining edge; 6. and connecting the threaded sleeve.
Detailed Description
Examples
Fig. 1 is the utility model relates to a long service life's soft sealing valve cross-sectional view, as shown in the figure, a long service life's soft sealing valve includes valve body 1, valve gap 2 and sets up valve rod 3 in valve body 1, 3 bottoms of valve rod are provided with rubber valve plate 4, 4 both sides of rubber valve plate are provided with the guide block (not drawn in the picture), be provided with direction slide 11 in the valve body 1, the embedded connection swivel nut 6 that is equipped with copper in 4 tops of rubber valve plate, valve rod 3 with connect 6 threaded connection of swivel nut for 4 vertical migration of rubber valve plate. The bottom of the rubber valve plate 4 is provided with a groove with a trapezoidal section to form two sealing surfaces 41, so that the sealing performance is greatly improved.
The position that valve body 1 is relative with the recess is provided with the arc manger plate and follows 5, and the arc manger plate is trapezoidal along 5 cross-sections, and the arc manger plate is followed 5 high 2mm, and is minimum to the medium flow influence, and the medium can be raiseed when following 5 through the arc manger plate and can not deposit dirty, and can wash the clearance number of times in the valve body 1 that significantly reduces to valve body 1 inside. The rubber valve plate 4 is arranged on the arc-shaped water retaining edge 5 in a spanning mode in the valve closing state, a certain fixing effect is achieved on the bottom of the rubber valve plate 4, deformation of the rubber valve plate 4 is greatly reduced, and therefore the overall service life of the valve is prolonged.
Therefore, the utility model adopts the above structure a long service life's soft sealing valve, rubber valve plate bottom is provided with the cross-section and forms two sealed faces for trapezoidal recess, has improved the leakproofness, sets up arc manger plate simultaneously and follows, plays certain fixed action to the rubber valve plate, avoids taking place deformation when the impact force of medium to rubber valve plate bottom is great under the closed condition, causes the rubber valve plate to damage, has improved the life-span of valve greatly, avoids the dead angle to deposit simultaneously dirty.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
