Abstract
The invention discloses a V-shaped ball valve, and belongs to the technical field of valves. The V-shaped ball valve comprises a valve body, a valve seat, a valve core, a valve rod, a transmission mechanism and a sealing piece assembly. The valve rod is composed of an upper valve rod and a lower valve rod. The V-shaped ball valve is characterized in that more than one layer of noise eliminating plate is arranged in a V-shaped notch of the valve core, the noise eliminating plates are fixedly connected with the valve core through bolts, and through holes are evenly formed in the noise eliminating plates so as to reduce washing noise of fluid to the valve core. The V-shaped ball valve has the advantages that when the fluid enters into the ball valve, the fluid penetrates through the valve core, the noise eliminating plates and is throttled, spread and expanded through the through holes formed in the noise eliminating plates, so that the fluid pressure is remitted, flow speed of fluid media is reduced, generation of noise is reduced effectively, and precision and service life of the ball valve are improved.
Description
Technical field
The present invention relates to valve technology field, especially relate to a kind of V-type ball valve.
Background technique
The V-type ball valve is comprised of valve body, valve seat, spheroid, valve rod, driving mechanism, Sealing and assembling set, and spheroid adopts semiglobe, and valve is comprised of the up and down valve rod, and spheroid and valve seat have the sealing surface that cooperatively interacts.At present, in control valve was used, there was a maximum limit in present most of manufacturer to the control valve noise.But, in actual applications, when some special workshop sections use conventional ball valve, be easy to noise and exceed standard, especially more outstanding in gas and steam workshop section use.
Summary of the invention
The present invention is to provide a kind of V-type ball valve for solving the problems of the technologies described above.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of V-type ball valve, comprise that valve body, valve seat, spool, valve rod, driving mechanism, Sealing form, described valve rod is comprised of upper valve rod and lower valve rod, it is characterized in that, be provided with the above muffler plate of one deck in the v-notch of described spool, described muffler plate is fixedly connected with described spool by bolt, on described muffler plate also all be distributed with through hole, for reducing the wash away noise of fluid to spool.
Described muffler plate is corrosion resistant plate.
The beneficial effect that the present invention has is, when fluid enters this ball valve, flow through spool, muffler plate and by the through hole on muffler plate with the rapid throttling diffusion of fluid with expand, thereby decomposed hydrodynamic pressure, reduced the flowing medium flow velocity, effectively reduce the generation of noise, improved ball valve precision and working life.
Description of drawings
Fig. 1 is the present invention: a kind of structural representation of V-type ball valve.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
With reference to shown in Figure 1, a kind of V-type ball valve, comprise that valve body 1, valve seat 4, spool 2, valve rod, driving mechanism 3, Sealing form, valve rod is comprised of upper valve rod 6 and lower valve rod 7, (being illustrated as three layers) muffler plate 8 be provided with one deck in " V " of described spool 2 type breach analogous shapes such as (or) " U " types more than, described muffler plate 8 is fixedly connected with described spool 2 by bolt 5, on described muffler plate 8 also all be distributed with through hole 9, for reducing the wash away noise of fluid to spool 2.Muffler plate 8 is the resistance to erosion corrosion resistant plate, is provided with a lot of through holes 9 at the plane machining of muffler plate 8.
When its cardinal principle entered this ball valve when fluid, the spool of flowing through, noise reducing plate also spread the rapid throttling of fluid and expand by the through hole on noise reducing plate, thereby have decomposed hydrodynamic pressure, have reduced the flowing medium flow velocity, have effectively avoided the generation of noise and cavitation erosion.
Above demonstration and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
