Abstract
The utility model discloses a multifunctional valve group which comprises an emptying sampling root valve, a meter root valve connected with a pressure meter and a forged steel tee joint communicated with a main body pipeline. One end of the forged steel tee joint is connected with the emptying sampling root valve, and the other end of the forged steel tee joint is connected with the meter root valve. Two bent connectors in the prior art are replaced by one forged steel tee joint, a welding mode for the forged steel tee joint is avoided, and weld joint cracks and leakage possibility are directly eliminated. Multiple pipelines led out of the main body pipeline are changed into one pipeline, and accordingly the pipeline layout is simple. Multiple original valve groups are changed into one valve group, all of functions are not changed, the connecting pipe length and flanges are decreased, weld cracks are decreased, and accordingly connector looseness or cracks of weld joints caused by pump vibration are avoided. An upper-mounted ball valve of an original control valve is replaced by a forged steel valve, and the forged steel valve is small in size, light in weight and long in service life and is sealed metallically.
Description
Technical field
The utility model relates to a kind of petroleum chemical industry valve, in particular a kind of multi-functional valve group.
Background technique
On the pump discharge pipeline of petroleum chemical industry, generally all can connect pressure gauge and emptying, lead pouring sampling cock, in order to connect these pressure gauges and emptying or sampling cock, conventionally on main pipeline, pick out multi units tube road and realize.
As shown in Figure 1, main body pipeline 1 ' is connected with two upper-mounting type ball valves 3 ' by two elbow connections 2 ' respectively, and elbow connection 2 ' all adopts welding manner with pipeline and flange, and because the vibration of pump discharge position is larger, leaking easily appears in the appearance of multistage pipeline.Particularly emptying or sampling cock, is upper-mounting type ball valve 3 ' due to what adopt, and volume is large, Heavy Weight, and sealing surface is nonmetallic material, thus the weld joint of external pipeline produces leakage because crackle more easily appears in vibration.Upper-mounting type ball valve is generally soft seal, and working life is shorter.Owing to being many group external pipelines, also bring inconvenience to layout of beam line in addition.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of multi-functional valve group is provided, and improves the sealing of pipeline.
The utility model is achieved through the following technical solutions, instrument root valve that the utility model comprises emptying sampling root valve, be connected with pressure gauge, with the forged steel threeway of main body pipeline connection; One end of described forged steel threeway connects emptying sampling root valve, and the other end connects instrument root valve.
One end of described forged steel threeway is fixed on main body pipeline, and the second end connects emptying sampling root valve by flange, and the 3rd end connects instrument root valve by flange.
Described emptying sampling root valve comprises the first Forging Steel Valve and short tube, and described short tube is welded on the first Forging Steel Valve, and threeway is connected by flange the first Forging Steel Valve with forged steel.
Described instrument root valve comprises the second Forging Steel Valve and union, and described the second Forging Steel Valve is connected with union, and union is connected on pressure gauge, and threeway is connected by flange the second Forging Steel Valve with forged steel.
The utility model has the following advantages compared to existing technology: the utility model adopts a forged steel threeway to substitute two elbow connections of the prior art, and welding manner has been avoided in forged steel threeway, has directly got rid of the possibility that occurs weld metal crack and leakage; The pipeline of drawing from main body pipeline is become together by multiple tracks, thereby makes pipe-line layout become simple; Original multiple valve groups are become to a valve group, and it is completely constant to realize all functions, and has reduced length and the flange taken over, reduced multiple-pass weld, thereby avoid because the vibration of pump causes that joint is loosening or crackle appears in weld seam; Original control valve upper-mounting type ball valve is changed into Forging Steel Valve, and the volume of Forging Steel Valve is little, and weight is little, is metal sealing, long service life.
Brief description of the drawings

Fig. 2 is structural representation of the present utility model.
Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under taking technical solutions of the utility model as prerequisite; provided detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 2, the present embodiment comprise emptying sampling root valve 2, the instrument root valve 3 being connected with pressure gauge 5, the forged steel threeway 4 being communicated with main body pipeline 1; One end of described forged steel threeway 4 connects emptying sampling root valve 2, and the other end connects instrument root valve 3.
One end of forged steel threeway 4 is fixed on main body pipeline 1, and the second end connects emptying sampling root valve 2, the three ends by flange and connects instrument root valve 3 by flange.
Emptying sampling root valve 2 comprises the first Forging Steel Valve 21 and short tube 22, and described short tube 22 is welded on the first Forging Steel Valve 21, and the first Forging Steel Valve 21 is connected by flange with forged steel threeway 4.
Instrument root valve 3 comprises the second Forging Steel Valve 31 and union 32, and described the second Forging Steel Valve 31 is connected with union 32, and union 32 is connected on pressure gauge 5, and the second Forging Steel Valve 31 is connected by flange with forged steel threeway 4.
Forged steel threeway 4 is to be processed by stamp forgings, and whole three-way component has a style of one's own, and without any leakage point, it has replaced two original elbow connections.One end of forged steel threeway 4 is connected with emptying sampling root valve 2 by flange, the other end is connected with instrument root valve 3 by flange, a multifunction valve group of common composition, this valve group is introduced the medium in main body pipeline 1 by forged steel threeway 4, control by emptying sampling root valve 2 realizes sampling or the function of emptying, can read by pressure gauge 5 pressure of main body pipeline 1 by the control of instrument root valve 3.
