Abstract
The utility model discloses a soft and hard sealed V-shaped adjusting ball valve. The soft and hard sealed V-shaped adjusting ball valve is characterized by comprising valve covers, an upper valve rod, a lower valve rod, end covers, valve seats and a ball body, wherein the upper valve rod and the lower valve rod are respectively positioned at the upper end and the lower end of the ball body; each valve cover is positioned on each side of the ball body; the end covers and the valve seats are positioned in the valve covers; convex rings are arranged on the valve seats; a first layer made of a material as the same as the material of a soft ball valve and a second layer made of a material as the same as the material of a hard ball valve are arranged in each convex ring. By the arrangement of the first layer and the second layer, pressure is directly born by a soft valve seat in the stress process of the ball body, and a hard valve seat is used as a main pressure bearing component, so that a soft material is extruded to generate elasticity and have restorability, thereby providing a lasting seal capacity.
Description
Technical field
The utility model relates to a kind of ball valve that regulates, and particularly relates to a kind of soft and hard seal V-type and regulates ball valve.
Background technique
Ball valve was come out the 1950's, and ball valve is along with scientific and technical develop rapidly, and updating of production technology and product structure, in the 40 short years, has developed rapidly and become a kind of main valve class.In the west flourishing country of industry, the use of ball valve is constantly risen year by year, in China, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.Ball valve comprises hard sphere valve, soft ball valve, spheroid etc., hard sphere valve with spheroid movement process in, due to hard sphere valve and both hard materials of spheroid, can generating portion reveal.That when soft ball valve has just started use, has revealed lacks, but because the time has been grown, flexible material deforms or be aging in the process of being pushed by ball valve, and a small amount of leakage still can occur.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of soft and hard seal V-type and regulates ball valve, it is owing to being provided with first layer and the second layer, spheroid is the direct pressure-bearing of soft valve seat in loading process, hard valve seat is pressure parts, so to soft material extruding for elasticity has can be restorative, possess lasting sealability.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of soft and hard seal V-type regulates ball valve, it is characterized in that, it comprises valve gap, upper valve rod, lower valve rod, end cap, valve seat, spheroid, upper valve rod, lower valve rod lay respectively at the two ends up and down of spheroid, valve gap lays respectively at a side of spheroid, end cap, valve seat are all positioned at valve gap, valve seat is provided with a bulge loop, is provided with the first layer second layer identical with hard sphere valve material with material that material is identical with soft ball valve material in bulge loop.
Preferably, the top of described upper valve rod is provided with a support, and support is provided with a transmission shaft.
Positive progressive effect of the present utility model is: because spheroid soft ball valve in loading process does not do main pressure-bearing forced element, so can not produce extruding local deformation to soft material, produce and reveal, do not need to do again in addition the switch valve of an insurance, cost reduction, efficiency improves.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model soft and hard seal V-type regulates ball valve.
Fig. 2 is the structural representation of end cap and valve seat in the utility model.
Fig. 3 is the structural representation of valve seat in the utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1 to Figure 3, the utility model soft and hard seal V-type regulates ball valve to comprise valve gap 1, upper valve rod 2, lower valve rod 3, end cap 6, valve seat 7, spheroid 8, upper valve rod 2, lower valve rod 3 lay respectively at the two ends up and down of spheroid 8, a valve gap 1 lays respectively at a side of spheroid 8, end cap 6, valve seat 7 are all positioned at valve gap 1, valve seat 7 is provided with a bulge loop 71, is provided with first layer 72 second layer 73 identical with hard sphere valve material with material that material is identical with soft ball valve material in bulge loop 71.
The top of upper valve rod 2 is provided with a support 4, and on support 4, cover has a transmission shaft 5, convenient like this rotation upper valve rod 2.
Owing to being provided with first layer and the second layer, spheroid soft ball valve in loading process does not do main pressure-bearing forced element, so can not produce extruding local deformation to soft material, produce and reveal, do not need to do again in addition the switch valve of an insurance, cost reduction, efficiency improves.
Above-described specific embodiment; technical problem, technological scheme and beneficial effect to solution of the present utility model further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. a soft and hard seal V-type regulates ball valve, it is characterized in that, it comprises valve gap, upper valve rod, lower valve rod, end cap, valve seat, spheroid, upper valve rod, lower valve rod lay respectively at the two ends up and down of spheroid, valve gap lays respectively at a side of spheroid, end cap, valve seat are all positioned at valve gap, and valve seat is provided with a bulge loop, are provided with the first layer second layer identical with hard sphere valve material with material that material is identical with soft ball valve material in bulge loop.
