Abstract
The utility model discloses a noise reduction and water hammer effect reduction long handle welded valve ball and a ball valve made of the same. The valve ball comprises a first valve rod, a valve ball body, a second valve rod and a valve body, wherein the first valve rod and the second valve rod are welded on the valve ball body, and the first valve rod and the second valve rod are symmetrical, equilong and coaxial. The valve ball is characterized in that a noise reduction board is arranged in the flow passage of the valve ball body; a plurality of noise reduction openings are formed in the noise reduction board; guide grooves are formed in the non-sealed surface of the valve ball body. The ball valve made of the noise reduction and water hammer effect reduction long handle welded valve ball comprises the valve body, wherein the first valve rod and the second valve rod extend out of the valve body. The ball valve has the advantages of noise reduction and water hammer effect reduction.
Description
Technical field
The utility model belongs to valve component, the ball valve that particularly a kind of noise reduction reduces water hammer effect long handle welded valve ball and makes.
Background technique
Ball valve, as one of conventional valve of industry, is usually used in unlatching and the cut-out of various industrial media.There is switch rapid, close tight feature.In power station, petrochemical industry, paper-making industry, space flight and aviation, Coal Chemical Industry, environmental protection, is used extensively.
The shortcoming of ball valve of the prior art in industrial production is used: in the time that fluid high-speed flows through process pipe, produce very large noise at ball valve place.Noise may reach 90-95 decibel; Fluid is in the time of valve closing, and fluid refluxes in shutoff place, but fluid dynamic energy can not disappear immediately.Two kinetic energy clash into formation water hammer mutually, cause very big bang, damage equipment and industrial pipeline.
Model utility content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of noise reduction, reduces the noise reduction reduction water hammer effect long handle welded valve ball of water hammer effect and the ball valve of making thereof.
The technical solution of the utility model is: a kind of noise reduction reduces water hammer effect long handle welded valve ball, comprise the first valve rod, valve ball, the second valve rod, the first valve rod, the second valve rod are welded on valve ball, and the first valve rod, second valve bar symmetric equal-length are coaxial, it is characterized in that: welding noise reducing plate in described valve ball runner, noise reducing plate is provided with some noise reductions hole; Described valve ball non-tight surface is provided with guiding gutter.
Further, guiding gutter is three parallel slots.
There is a kind of noise reduction and reduce the ball valve that water hammer effect long handle welded valve ball is made, comprise valve body, it is characterized in that: the first valve rod, the second valve rod all stretch out outside valve body.
The utility model has the advantages of and be: this noise reduction reduces the ball valve that water hammer effect long handle welded symmetrical valve ball is made, in the time flowing through the ball valve made from noise reduction reduction water hammer effect valve ball, owing to being welded with noise reducing plate in ball valve, upset Nei Bu Liu Chang, make noise can reduce 5-10 decibel; In the time that fluid is closed, noise reduction reduces on water hammer effect ball valve valve ball guiding gutter, and when fluid flows through spheroid, fluid produces backflow on guiding gutter, and fluid forms head-on collision, and fluid dynamic energy is cancelled out each other, and reduces water hammer.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of noise reduction reduces water hammer effect long handle welded valve ball, comprise the first valve rod 1, valve ball 2, the second valve rod 3, the first valve rod 1, the second valve rod 3 are welded on valve ball 2, and the first valve rod 1, the second valve rod 3 symmetric equal-lengths are coaxial, it is characterized in that: welding noise reducing plate 21 in described valve ball 2 runners, noise reducing plate 21 is provided with some noise reductions hole 22; Described valve ball 2 non-tight surfaces are provided with guiding gutter 23.
Further, guiding gutter 23 is three parallel slots.
There is a kind of noise reduction and reduce the ball valve that water hammer effect long handle welded valve ball is made, comprise valve body 4, it is characterized in that: the first valve rod 1, the second valve rod 3 all stretch out outside valve body 4.
More than that a kind of noise reduction provided by the utility model is reduced water hammer effect long handle welded symmetrical valve ball and makes ball valve; be described in detail; the present embodiment is just for helping to understand design method of the present utility model and core concept; simultaneously; to those skilled in the art; according to the identical swivel joint of essence of thought design of the present utility model, all within the utility model protection domain.
In sum, this description can not be interpreted as restriction of the present utility model.
