The outlet of the pressure reducing valve has an outlet connection used to switch on the stove with burner via the rubber tube, the external end of the inlet tube of the pressure reducing valve is provided with an inlet connection used to switch on via the metal tube or directly switch on the outlet of the angle valve of the liquefied gas cylinder, and a safety valve and a pressure gauge are arranged on the inlet tube of the pressure reducing valve. When lots of gas spills and leaks, the safety valve can automatically close the air source, the pressure gauge can display the stored gas quantity of the liquefied gas cylinder and can be used to detect whether the pipeline leaks. Therefore, the utility model is safe and convenient in use.
Description
The utility model relates to the liquefied gas decompressor that a kind of family and unit use, particularly a kind of safety-type liquefied gas decompressor with security personnel and measuring ability.
In the prior art, liquefied gas decompressor commonly used only is a pressure-reducing valve, and its outlet has an outlet connection that is used for connecting by rubber tube burner, and there is an inlet union that is used for connecting by metal tube the liquefied gas bottle angle valve its inlet tube outer end.Use this liquefied gas decompressor, be difficult to the gas leakage of signal piping and burner, can not demonstrate the tolerance of depositing in the liquefied gas bottle, thereby use safety inadequately, it is convenient inadequately to use.
The purpose of this utility model is to provide a kind of safe in utilization, safety-type liquefied gas decompressor easily.
In order to achieve the above object, the utility model adopts following technical proposals: the utility model is the same with prior art to include a pressure-reducing valve, the outlet of pressure-reducing valve has an outlet connection that is used for connecting by rubber tube burner, and there is day joint that advances that is used for connecting or directly connecting by metal tube the outlet of liquefied gas bottle angle valve the inlet tube outer end of pressure-reducing valve.It is characterized in that: a safety valve and a Pressure gauge are housed on the inlet tube of pressure-reducing valve.In use, if the rubber tube season cracking occurs, serious gas leakage situation such as come off, the throughput by safety valve strengthens suddenly, and then safety valve can cut out source of the gas automatically, avoids disaster to take place.Pressure gauge has been arranged, then demonstrated the tolerance of depositing in the liquefied gas bottle at any time.And can utilize Pressure gauge to come the signal piping system whether to leak gas.Detection method is: close the burner switch, open the liquefied gas bottle angle valve, press list index to show that pressure rises, close the liquefied gas bottle angle valve then, internal pressure list index demonstration in 5 seconds pressure does not have obvious falling, and then pipe-line system is air tight, can relievedly use, otherwise should in time overhaul.
The structure of above-mentioned safety valve can be designed as: rubber valve seat of suit in the endoporus of pressure-reducing valve inlet tube, before rubber valve seat, settle a spherical valve core, the tubular valve body that is fixedly connected on the pressure-reducing valve inlet tube is being arranged above the spherical valve core, push rod of coupling slides in tubular valve body lower central hole, the lower end aligned spherical valve core of push rod, and there is flange bearing the upper end on little spring, has a case to be covered with little spring and push rod, the moving coupling of the external slyness of the endoporus of case and cylindrical valve.The operation principle of safety valve is: under normal operating position, spherical valve core is by himself gravity sinking, thereby the unlatching of the valve port of rubber valve seat, and liquefied gas freely flows through safety valve; When situation such as the rubber tube explosion occurs or come off, the throughput by safety valve strengthens suddenly, and spherical valve core is blown down by powerful air-flow on the valve port that promptly is attached to rubber valve seat, thereby closes source of the gas; After the pipeline maintenance, the case of safety valve that press...withes one's finger, then push rod gets off the valve port roof fall of spherical valve core from rubber valve seat, and safety valve is opened ventilation.It is the Pressure gauge of 0-1.0MPa that above-mentioned Pressure gauge can be selected the dial plate indicating range for use.
The utility model compared with prior art, have following show and the easy advantage of wind: the utility model is equipped with safety valve, when the fortuitous event of a large amount of gas spill and leakages occurring, can close source of the gas automatically, avoids disaster to take place, and is safe in utilization.Whether the utility model also is equipped with Pressure gauge, can show that liquefied gas bottle deposits tolerance, and be used for the detector tube system and leak gas, and is safe in utilization, convenient.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the outside drawing of an embodiment of the utility model.
Fig. 2 is the profile at A-A place among Fig. 1.
An optimum implementation of the present utility model is: referring to Fig. 1 and Fig. 2, intrinsic safety holotype liquefied gas decompressor includes a pressure-reducing valve 2, the outlet of pressure-reducing valve 2 has an outlet connection 1 that is used for connecting by rubber tube burner, and outlet connection 1 is pagoda shape joint, directly socket rubber tube.There is an inlet union 6 that is used for connecting or directly connecting by metal tube the outlet of liquefied gas bottle angle valve inlet tube 4 outer ends of pressure-reducing valve 2.A safety valve 5 and a Pressure gauge 3 are housed on the inlet tube 4 of pressure-reducing valve 2.The structure of safety valve is: rubber valve seat 24 of suit in the endoporus of pressure-reducing valve 2 inlet tubes 4, before rubber valve seat 24, settle a spherical valve core 23, the tubular valve body 13 that is fixedly connected on the pressure-reducing valve inlet tube 4 is being arranged above the annular spool 23, push rod 15 of coupling slides in tubular valve body 13 lower central holes, the lower end aligned spherical valve core 23 of push rod 15, and there is flange bearing the upper end on little spring 14, have a case 16 to be covered with little spring 14 and push rod 15, the endoporus of case 16 and tubular valve body 13 cylindricals slide and mate.It is the Pressure gauge of 0-1.0MPa that Pressure gauge 3 is selected the dial plate indicating range for use.The structure of pressure-reducing valve 2 is: valve body 29 is cast into one with outlet connection 1 and inlet tube 4, a valve gap 7 is fixed on a round film 12 between valve body 29 and the valve gap 7 by screw, epithelium 12 upper surfaces are supporting a spring 8, spring 8 upper ends are by 9 supportings of a blade, blade 9 cylindricals and valve gap 7 upper end inner hole threads spin, there is a top cover 10 valve gap 7 upper ends, the center of epithelium 12 is connected with the left end of a lever 28 by a pin 11, the middle part of lever 28 is hinged by pin 27 and valve body 29, the right-hand member lower surface of lever 28 is fixed a little rubber 25, and little rubber 25 is covered with an intake valve port 26.Turn on top cover 10,, then can adjust the thrust of 8 pairs of epitheliums 12 of spring, thereby adjust the aperture of 25 pairs of intake valve ports 26 of little rubber, can reach the purpose of adjusting pressure-reducing valve 2 outlet air pressure with copper plate rotation blade 9.The structure of inlet union 6 is: the sleeve pipe 22 that flange 19 is arranged in end of the tight cover of pressure-reducing valve 2 inlet tubes 4 end endoporus, a rubber tip 20 is tightly being overlapped in these sleeve pipe 22 outer ends, these rubber tip 20 endoporus are installed a filter screen 21, and one of slip suit has the male connector 18 of handwheel 17 on inlet tube 4 end cylindricals.
