Abstract
The utility model discloses a cavitation-preventive noise reduction type V-shaped ball valve, which comprises a valve body (1), a valve seat (4), a valve spool (7), a valve stem, packing (11), a packing press cover (12) and a rear press cover (20). A noise reduction plate (8) provided with a through hole (23) is mounted on a 'V'-shaped notch of the valve spool (7). The valve seat (4) is mounted at the lateral edge of the valve body (1) by the aid of a sealing seat cover (2), and a wave spring (5) is mounted between the sealing seat cover (2) and the valve seat (4). When flowing into the ball valve, fluid flows through the valve spool and the noise reduction plate, and is rapidly throttled, diffused and expanded by the aid of the through hole on the noise reduction plate. Accordingly, pressure of the fluid is decomposed, flow rate of fluid media is reduced, noise is effectively lowered, cavitation is effectively reduced, precision of the ball valve is improved, the service life of the ball valve is prolonged, and the valve can be repaired more conveniently by the aid of the unique lateral-mounted valve seat.
Description
Technical field
The utility model relates to a kind of Ball valve.
Technical background
At present, in control valve was used, all there was a maximum limit in present most of manufacturer to the control valve noise.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.Water and other liquid also will produce cavitation erosion under the environment of High Pressure Difference and the infringement pipe-line system will influence greatly to the working life and the precision of ball valve.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of V-type ball valve that can effectively prevent cavitation erosion, noise reduction sound is provided.
The purpose of this utility model realizes by following technical solution: a kind of anti-cavitation erosion noise reduction formula V-type ball valve, comprise valve body, valve seat, spool, valve rod, filler and Gland, rear pressing cover, the noise reducing plate of band through hole is housed in " V " of described spool type breach.
After adopting the utility model structure, when fluid enters this ball valve, flow through spool, noise reducing plate and by the through hole on the noise reducing 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 and cavitation erosion, improved ball valve precision and working life.
Description of drawings
Fig. 1 is the structural representation of the anti-cavitation erosion of the utility model noise reduction formula V-type ball valve.
Fig. 2 is a waveform spring configuration schematic representation among Fig. 1.
Fig. 3 is the side view of Fig. 2.
Embodiment
With reference to accompanying drawing 1, the anti-cavitation erosion of the utility model noise reduction formula V-type ball valve, comprise valve body 1, valve seat 4, spool 7, valve rod (being made of upper valve rod 9, lower valve rod 16), filler 11 and Gland 12 (and gland stud 13, nut 14), rear pressing cover 20 (and gland bolt 21), (by bolt 24) is equipped with the noise reducing plate 8 of being with through hole 23 in " V " of described spool 7 type breach analogous shapes such as (or) " U " types.Noise reducing plate 8 is made up of the anti-corrosion resistant plate that washes away of multilayer (be at least two layers, be illustrated as three layers), is provided with a lot of through holes 23 in the processing of the plane of noise reducing plate 8.When its cardinal principle enters this ball valve when fluid, the spool of flowing through, noise reducing plate and by the through hole on the noise reducing plate with the rapid throttling diffusion of fluid with expand, thereby decomposed hydrodynamic pressure, reduced the flowing medium flow velocity, effectively avoided the generation of noise and cavitation erosion.
Wherein, valve body 1 adopts the integrated type optimal design, has avoided valve body to connect the leakage that causes because of adopting flange like this; Spool 7 is designed to special " V " type breach, makes valve have the Flow characteristics of approximate equal percentage.This design makes ball valve have very big shearing force and self-cleaning function when possessing accurate control performance; Spool adopts upper and lower valve rod 9,16 and upper and lower bearing 10,25 to fix, and has high rotating accuracy and rotational stability.Upper and lower duplex bearing adopts the stainless steel surfaces sintered copper and makes at the special process of copper surface rolling PTFE, have superpower wear-resisting property and self-lubricating function, has avoided the generation of valve valve rod and bearing seizure phenomenon in long-term the use; As shown in Figure 1 to Figure 3, described valve seat 4 is contained in the side of valve body 1 by sealing flap 2 (and hexagon socket head cap screw 3), and between sealing flap 2 and the valve seat 4 wavy spring 5 is housed.This creates side-mounted valve seat, makes that the maintenance of valve is convenient.
Claims (2)
1. prevent cavitation erosion noise reduction formula V-type ball valve for one kind, comprise valve body (1), valve seat (4), spool (7), valve rod, filler (11) and Gland (12), rear pressing cover (20), it is characterized in that: the noise reducing plate (8) that band through hole (23) is housed in " V " of described spool (7) type breach.
2. anti-cavitation erosion noise reduction formula V-type ball valve as claimed in claim 1 is characterized in that: described valve seat (4) is contained in the side of valve body (1) by sealing flap (2), and between sealing flap (2) and the valve seat (4) wavy spring (5) is housed.
