Abstract
The invention discloses a long and short handle welding type asymmetric valve ball and a ball valve made from the same. The ball valve comprises a first valve rod (1), a valve ball (2) and a second valve rod (3). The ball valve is characterized in that the first valve rod (1) and the second valve rod (3) are welded on the valve ball (2), the first valve rod (1) and the second valve rod (3) are not asymmetric and coaxial, and the first valve rod (1) is longer than the second valve rod (3). The invention provides the long and short handle welding type asymmetric valve ball and the ball valve made from the same with the advantages of simple structure, long service life and low maintenance cost.
Description
Technical field
A kind of valve component of the present invention, the particularly asymmetric valve ball of a kind of long/short handle welding type and the ball valve made thereof.
Background technique
Ball valve as one of industry valve commonly used, is usually used in unlatching and the cut-out of various industrial media.Have switch rapid, close tight characteristics.In the power station, petrochemical industry, paper industry, space flight and aviation, Coal Chemical Industry, environmental protection is used extensively.The shortcoming of existing ball valve in industrial production is used:
At first, the life-span is short.Because the ball valve normal operation is in high concentration, height contains the coal slurry of solid, and in the industrial fluids such as Heisui River buck ore pulp, erosive wear is inevitably, so the life-span is short, and is most of about 1 year, that have even shorter.
Secondly, rate of fault is high.Ball valve in some uses is brought into use normally, and the operation some months turns motionless.Be forced to improve work bleed pressure booste operation, some months has not rotated again, pull down maintenance.
Again, actuator's volume is large, Heavy Weight, and cost is high, and energy consumption is high.Be with motionless valve ball because actuator easily appears in ball valve, so just join large actuator, some ball valves are joined tens0000 newton's actuator.Weight reaches about 3 tons, and the lifting difficulty is installed.Simultaneously the pipeline offset loading force is increased.Actuator is large, charges and discharge instrument air tolerance just large at every turn, and instrument air also is the air compressor compression, is equivalent to consume the energy more.Actuator is large, and cost is certainly high, and the user will spend more money
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides the low asymmetric valve ball of a kind of long/short handle welding type of a kind of simple in structure, long service life, maintenance cost and the ball valve of making thereof
Technological scheme of the present invention is: the asymmetric valve ball of a kind of long/short handle welding type, comprise the first valve rod 1, valve ball 2, the second valve rod 3, it is characterized in that: the first valve rod 1, the second valve rod 3 are welded on the valve ball 2, and the first valve rod 1, the second valve rod 3 are asymmetric coaxial, and the first valve rod 1 is longer than the second valve rod 3.
Ball valve according to the asymmetric valve ball of described a kind of long/short handle welding type is made comprises valve body 4, and it is characterized in that: the first valve rod 1 stretches out outside the valve body 4, and the second valve rod 3 also stretches out valve body 4.
Described valve body (4) is midsplit type or middle dress formula.
Of the present invention have an effect to be: the invention provides the low asymmetric valve ball of a kind of long handle welded of a kind of simple in structure, long service life, maintenance cost and the ball valve of making thereof.
Description of drawings:
Fig. 1 is the asymmetric valve ball structure schematic diagram of a kind of long/short handle welding type of the present invention
Fig. 2 is the ball-valve structure schematic diagram that the asymmetric valve ball of a kind of long/short handle welding type of the present invention is made
Accompanying drawing indicates: 1 is the first valve rod, and 2 is valve ball, and 3 is the second valve rod, and 4 is valve body.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is further described
As shown in Figure 1, the asymmetric valve ball of a kind of long/short handle welding type comprises the first valve rod 1, valve ball 2, the second valve rod 3, it is characterized in that: the first valve rod 1, the second valve rod 3 are welded on the valve ball 2, and the first valve rod 1, the second valve rod 3 are asymmetric coaxial, and the first valve rod 1 is longer than the second valve rod 3.
As shown in Figure 2, the ball valve according to the asymmetric valve ball of described a kind of long/short handle welding type is made comprises valve body 4, and it is characterized in that: the first valve rod 1 stretches out outside the valve body 4, and the second valve rod 3 also stretches out valve body 4.Described valve body (4) is midsplit type or middle dress formula.
More than be to the asymmetric valve ball of a kind of long handle welded provided by the present invention and make ball valve; be described in detail; the present embodiment just is used for helping to understand design method of the present invention and core concept; simultaneously; to those skilled in the art; according to the identical swivel joint of thought essence of design of the present invention, all within protection domain of the present invention.
In sum, this description can not be interpreted as limitation of the present invention.
