Abstract

The utility model relates to a pressure-reducing valve block, in particular to a sound-damping pressure-reducing valve block used in the metallurgical industry. The utility model mainly consists of an entry conical tube, a tail conical tube as well as four straight tubes, four front flared conical tubes and four rear flared conical tubes, which are connected between the entry conical tube and the tail conical tube. The tail end of the entry conical tube is connected with the straight tube, and the exit end of the straight tube is connected with the front flared conical tube through a pressure-adjusting valve. The exit end of the rear flared conical tube is connected with the tail conical tube. The utility model is characterized in that the exit end of the front flared conical tube is connected with the entry end of the rear flared conical tube by connecting in series with a single-chambered component filter. A meridian-helix shielding device is respectively arranged in the entry end of the four straight tubes. A gradually-expanding conical multi-leaf orificed spreader is respectively arranged at a site 2 to 10 times of the distance from the circulating diameter of the pressure-adjusting valve in the rear flared conical tube and in the exit end of the rear flared conical tube. A honeycombed sound absorber is respectively arranged on the inner surface of the joint of the tail conical tube and the rear flared conical tube as well as on the inner surface of the tail conical tube. The pressure-reducing valve block has excellent sound-damping effect and the functions of dust prevention, blockage prevention and corrosion resistance, etc.

Description

Noise reduction formula reduction valve group

One, technical field

The utility model relates to a kind of reduction valve group, especially a kind of noise reduction formula reduction valve group that is used for metallurgy industry.

Two, background technique

At present, the noise that used reduction valve group produces when control, conveying high temperature and high pressure gas in the metallurgy industry all is the mode that adopts passive noise reduction, promptly at pipeline and reduction valve group outer end parcel quieter material, needing bigger parcel space, is to treat to eliminate after noise sends again, and does not take measures in pipe-line system, sound-deadening and noise-reducing weak effect not only, and reduction valve group and pipeline increase the repair cycle owing to the serious wear that exists of dust, influence ordinary production.

Three, summary of the invention

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of good muffling effect, dustproof, anti-blocking, antiwear noise reduction formula reduction valve group are provided.

For achieving the above object, the technology that the utility model adopts is put case and is: a kind of noise reduction formula reduction valve group, mainly comprise the import Taper Pipe, tail cone pipe and be connected in four straight tubes between the two, four preceding enlarging Taper Pipes, enlarging Taper Pipe after four, the end of import Taper Pipe is connected with the entrance point of four straight tubes, the outlet end of straight tube is connected by the entrance point of pressure regulator valve with preceding enlarging Taper Pipe respectively, the outlet end of back enlarging Taper Pipe is connected with the tail cone pipe, its special way is, the outlet end of four preceding enlarging Taper Pipes all passes through the single chamber component filters of serial connection and is connected with the entrance point of enlarging Taper Pipe after four; In the entrance point of four straight tubes, be separately installed with meridian helical shield device; Back enlarging Taper Pipe is separately installed with the conical leafy aperture of flaring and divides flow cone in the Taper Pipe of 2-10 times of distance of distance pressure regulator valve circulation diameter and in the outlet end of back enlarging Taper Pipe; All be equipped with the honeycomb shock absorber at the internal surface of tail cone Guan Yuhou enlarging Taper Pipe joint and the internal surface of tail cone pipe.

The good effect that compared with the prior art the utility model has is that the meridian helical shield device that is installed in the straight tube entrance point can be blocked the noise forward pass that produces with the check valve group effectively; Design that it is distinctive " flow cone is divided in the conical leafy aperture of flaring ", have disperse with the alleviation two phase flow between active force, absorption and the decay that the multi-efficiency of cutting apart energy head, direct fluid potential energy has interference wave simultaneously concurrently; Series type list chamber component filters can absorb by the relaxation of serial connection chamber and successional the subduing of fully dissipating, and also has dustproof, anti-blocking performance when improving the noise reduction ability; It is a kind of desirable interior noise reduction product of pipe-line system.

Fig. 2 is the A-A sectional view.

Fig. 3 is the B-B sectional view.

Fig. 4 is the C-C sectional view.

Five, embodiment

For understanding the utility model better, it is described in further detail below in conjunction with drawings and Examples.

With reference to Fig. 1-Fig. 4 as seen, noise reduction formula reduction valve group described in the utility model mainly is by import Taper Pipe 1, tail cone pipe 8 and be connected in four straight tubes 3 between the two, four preceding enlarging Taper Pipes 5, enlarging Taper Pipe 7 constitutes after four, the end of import Taper Pipe 1 is connected with the entrance point of four straight tubes 3, the outlet end of straight tube 3 is connected with the entrance point of preceding enlarging Taper Pipe 5 by pressure regulator valve 4 respectively, the outlet end of back enlarging Taper Pipe 7 is connected with tail cone pipe 8, the outlet end of four preceding enlarging Taper Pipes 5 is connected with the front end of the single chamber component filters 6 of serial connection, and the end that is connected in series single chamber component filters 6 is connected in series with the entrance point of enlarging Taper Pipe 7 after four; In the entrance point of four straight tubes 3, be separately installed with meridian helical shield device 11; Back enlarging Taper Pipe is separately installed with the conical leafy aperture of flaring and divides flow cone 10 in the Taper Pipe of 2-10 times of distance of distance pressure regulator valve circulation diameter, be separately installed with the conical leafy aperture of flaring and divide flow cone 12 in the outlet end of back enlarging Taper Pipe 7; All be equipped with honeycomb shock absorber 9 at tail cone pipe 8 and the internal surface of back enlarging Taper Pipe 7 joints and the internal surface of tail cone pipe 8.

Above-mentioned noise reduction formula reduction valve group is applicable to subdues the noise that high and low pressure, strong reduction, highly corrosive gas produce in course of conveying in the industries such as metallurgy, chemical industry, thermoelectricity, and have the flowing medium of preventing and in course of conveying, carry dregs such as dust, moisture, alleviate wearing and tearing or corrosion to pipeline, in order to avoid influence ordinary production, be a kind of desirable sound-deadening and noise-reducing product.
