Abstract
The utility model provides a kind of high-performance metallic seal slurry valve, comprise valve body, valve seat, valve plate, valve rod, valve gap, valve seat is arranged in valve body, and valve plate is placed in valve body, when flashboard is in closed, valve seat and valve plate form seal combination, valve gap is fixed on valve body upper-end surface, and valve rod links through valve gap and flashboard, and the bottom of valve plate has arc groove, valve plate selects stainless steel, and the roughness value on valve plate surface is 0.2-0.4.Have that wear resistance is good, long service life, the feature that normally can work at the pressure of 105Mpa.
Description
Technical field
The utility model relates to mud valve technical field, is specifically related to a kind of high-performance metallic seal slurry valve.
Background technique
The gate valve that domestic current oil field and mine use; due in underground medium containing silt and Hard Inclusion and sulphur-containing substance; in the motion of fluid, spool and valve seat washed away and corrode; cause valve plate and the prooving of valve seat and corrosion very fast, during closedown, have leakage phenomenon, often need to change; not only cost of production expense increases; affect manufacturing efficiency, the more important thing is that the mine midway shutdown maintenance of working continuously changes loss quite large, and there is unsafe factor.
Traditional mud valve uses General Purpose Rubber at sealing station, and the oil resistance of rubber is bad, and the mud valve compressive strength that rubber does is 35Mpa to the maximum, and this just greatly limit its using scope.
Model utility content
Technical problem to be solved in the utility model overcomes defect of the prior art, provide that a kind of wear resistance is good, long service life, can under the pressure of 105Mpa the high-performance metallic seal slurry valve of stable operation.
For solving the problems of the technologies described above, the utility model provides a kind of high-performance metallic seal slurry valve, comprises valve body, valve seat, valve plate, valve rod, valve gap, and valve seat is arranged in valve body, valve plate is placed in valve body, when flashboard is in closed, valve seat and valve plate form seal combination, and valve gap is fixed on valve body upper-end surface, valve rod links through valve gap and flashboard, the bottom of valve plate has arc groove, and valve plate selects stainless steel, and the roughness value on valve plate surface is 0.2-0.4.
As further improvement of the utility model, between valve plate with valve rod, adopt T-shaped connection.
The beneficial effect that the utility model reaches is: valve plate adopts the stainless steel material through supersonic spray coating process, and hardness can reach HV1000, improves wear-resisting property, can bear the pressure of 105Mpa simultaneously; Roughness reaches 0.2-0.4, ensure that the sealability between valve rod and valve seat, does not need additionally to increase seal ring again, the bottom of valve plate is provided with arc groove simultaneously, can allow the mud of thickness quickly through, reduce mud and infringement washed away to valve plate, increase the service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of valve plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in the figure, the utility model provides a kind of high-performance metallic seal slurry valve, comprise valve body 1, valve seat 2, valve plate 3, valve rod 4 and valve gap 5, valve seat 2 is arranged in valve body 1, valve plate 3 is placed in valve body 1, when rotation hand wheel 6 makes flashboard be in closed, valve seat 2 and valve plate 3 form seal combination, valve gap 5 is fixed on valve body 1 upper-end surface, valve rod 4 links through valve gap 5 and flashboard 3, valve plate 3 selects stainless steel, surface is through supersonic spray coating process, hardness reaches HV1000, roughness value reaches 0.2-0.4, not only increase the wear-resisting property of valve plate, valve plate normally can be worked under the pressure of 105Mpa, and ensure that closely cooperating between valve plate and valve seat, solve due to valve plate rough surface, good sealing can not be realized with valve seat, need the problem being ensured sealing by seal ring, arc groove is had in the bottom of valve plate 3, can allow the mud of thickness quickly through, reduce mud and infringement washed away to valve plate, increase the service life, in addition T-slot is set in the upper end portion of valve plate 3, realizes being connected with the T-shaped of valve rod 4, there is the feature of automatic deflection adjusting.Dispatch from the factory assembling time, on the top of valve rod 4, guard shield 7 is also installed, is used for protecting the screw thread of valve rod 4 upper end portion.
Only preferred implementation of the present utility model described in upper; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
Claims (2)
1. a high-performance metallic seal slurry valve, comprise valve body, valve seat, valve plate, valve rod, valve gap, described valve seat is arranged in valve body, and described valve plate is placed in valve body, when flashboard is in closed, valve seat and valve plate form seal combination, described valve gap is fixed on valve body upper-end surface, and valve rod links through valve gap and flashboard, it is characterized in that: the bottom of described valve plate has arc groove, described valve plate selects stainless steel, and the roughness value on valve plate surface is 0.2-0.4.
2. high-performance metallic seal slurry valve according to claim 1, is characterized in that: described valve plate with adopt T-shaped connection between valve rod.
