The pressure control valve group solves the problems existing in the original valve groups of small safety factors, non-compact structure, unequal quality, etc. The self-operated pressure control valve group is provided with at least one self-operated pressure control valve in the middle of a main pipeline, and each self-operated pressure control valve is connected with a flow control valve by a valve back fire retardant tube, wherein, stop valves or ball valves are respectively arranged on both sides of the self-operated pressure control valve and the flow control valve, a pressure gauge is arranged at the side face of each stop valve or each ball valve, a filter is arranged on the head of the main pipeline, the tail end of the main pipeline is provided with a flow orifice plate, a safety valve and a check valve. The pressure control valve group has compact structure, changeful combinations, neat design, convenient operation, high safety factors, small space occupation, balanced movement, good rigidity, compact joint between each valve, wide selected range and high sensitivity.
Description
Technical field:
The utility model relates to a kind of pressure regulator valve group that pilot-gas medium process can be carried out the lowering and stabilizing blood pressure function automatically that is used for.
Background technology:
In metallurgy industry oxygen enriched blast and the converter top-blow engineering combination of gases instrument valve still adopted by processing parameter at present and purchase assembling disaggregatedly.This aggregate erection safety coefficient is little, structure is not compact, quality is unequal, various valve manufacturing process complexity connects inaccurately, and purchasing procedure is heavy, transportation and installation costs height, very inconvenience of operation.
Summary of the invention:
In order to solve the problem of above-mentioned existence, the utility model provides this valve block structure compactness, makes up changeablely, and design is dexterous, the self-contained pressure regulator group easy to operate, that safety coefficient is high; This valve group takes up space little, the operation balance, good rigidly, the parameter of each valve connects and connects compactness, selects for use scope wide, and is highly sensitive, be a kind of need not the external energy, multi-functional, the modular self-contained pressure regulator group that forms a complete set of of self regulating.The purpose of this utility model is achieved through the following technical solutions: the self-contained pressure regulator group, at the middle part of Trunk Line at least one self-contained pressure regulator is set, each self-contained pressure regulator and flow control valve are by back-fire relief pipe coupling behind the valve, be separately installed with stopping valve or ball valve in the both sides of self-contained pressure regulator and flow control valve, tensimeter is equipped with in side at stopping valve or ball valve, head at Trunk Line is equipped with strainer, at the afterbody of Trunk Line fow-through orifice, safety valve, vacuum breaker is housed.
Connect the take-off line that is made of back-fire relief pipe, self-contained pressure regulator behind stopping valve or ball valve, flow control valve, the valve on the described Trunk Line, the end of take-off line is connected with the tensimeter of Trunk Line.
The beneficial effects of the utility model: self-contained pressure regulator and flow control valve are the core components in the whole pressure regulator valve group, wherein self-contained pressure regulator is a kind ofly to need not the external energy and only rely on and transferred the pressure change of medium itself to carry out the self-regulating energy-saving product of pressure, set the downstream pressure value according to self processing requirement on the guiding command system of pressure regulator valve in the equipment debugging process, pressure regulator valve will be adjusted to bleed pressure the downstream pressure of setting and keep automatically that it is constant.The main valve flow control valve is as the performer in the valve group, is one of important in the production process varitrol, is used for processing parameters such as Long-distance Control gas downstream flow, pressure in master control room.For guaranteeing the stability and the reliability of system works, in the pressure regulator valve group, wherein Trunk Line as one independently pressure regulate working group; Another working group's board closing condition of take-off line is used as emergency power working group.Fow-through orifice is used for gas on-site pressure regulator valve group actual process parameter looked for and feeds back to master control room, share the family on-the-spot pressure regulator valve group of remote control and regulation easily.The utility model novel structure makes up changeablely, and design is dexterous, and unified appearance coordinates, easy to operate, and it is little to take up space, moving equilibrium, and good rigidly is connected compact between each valve, select for use scope wide, and highly sensitive, adjustability is good.The import and export nominal diameter of valve group can be different, i.e. the diameter of a kind of import, and the outlet that can be furnished with several nominal diameters, suitability is good, safe and reliable, the long service life of the wide maximum characteristics of use range.Tool corrosion resistant, antioxygen and fire-retardant characteristic have advantages such as safe, reliable, efficient, energy-conservation simultaneously.
Description of drawings:
Fig. 1 is the structural representation of self-contained pressure regulator group.
Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail: the self-contained pressure regulator group, comprise by self-contained pressure regulator 6, stopping valve 4,10, flow control valve 8, back-fire relief pipe 16 behind the valve, tensimeter 2,11 Trunk Lines that constitute, one end of self-contained pressure regulator 6 is connected with flow control valve 8 by back-fire relief pipe 16 behind the valve, the other end of self-contained pressure regulator 6 is connected with stopping valve 4, flow control valve 8 is connected with stopping valve 10, stopping valve 4,10 respectively with tensimeter 2,11 connect, head at valve group Trunk Line is equipped with strainer 1, strainer 1 is connected with stopping valve 4, stopping valve 10 is connected with fow-through orifice 12, in valve group end vacuum breaker 14 is housed, vacuum breaker 14 is connected with safety valve 13.
1 self-contained pressure regulator wherein is set on the Trunk Line at least, and each pressure regulator valve need corresponding assembly be supporting is connected with back-fire relief pipe behind flow control valve, stopping valve or ball valve, the valve etc.
The utility model self-contained pressure regulator group can be provided with take-off line as required, take-off line by stopping valve 9,3, flow control valve 7, self-contained pressure regulator 5, valve after back-fire relief pipe 15 constitute, the same Trunk Line of the mode of connection of above-mentioned parts, both ends stopping valve 9,3 are connected with the tensimeter 11,2 of Trunk Line respectively.
Stopping valve 3,4,9, the 10 also available ball valves that the utility model adopts replace.
Source of the gas enters Trunk Line in the direction of arrows during work, tensimeter 2 shows upstream pressure, according to self processing requirement after setting the downstream pressure value on the command system of self-contained pressure regulator 5, self-contained pressure regulator 5 can be regulated bleed pressure automatically and keep constant, and flow control valve 8 is regulated flow simultaneously.When Trunk Line breaks down maybe need overhaul the time, stopping valve 4,10 ends source of the gas, and source of the gas will enter the take-off line of being made up of stopping valve 3, self-contained pressure regulator 5, flow control valve 7, stopping valve 9, the carrying out that adjusting work goes round and begins again.
