The device is characterized in that no pollution and no adhesion are produced, twice of rated outlet pressure safe exhaust pressure value and exhaust flow is enabled to be more than or equal to the rated flow, so that the defects of the safe exhaust device of an existing gas pressure regulator are overcome, the safety exhaust device of the gas pressure regulator has a compact structure, reasonable and unique layout, a small size and high sensitivity, the cost is reduced, the working efficiency is improved, the personal equipment and the use safety of equipment are practically and effectively protected, the needs of modern hi-tech development can be fully met, and creativity and novelty are realized.
Description
Technical field
The present invention relates to gas regulator and make the field, relate in particular to a kind of structure and method field of manufacturing of gas regulator safety guard.
Background technology:
Existing gas regulator safety guard; Adopt sheet rubber to do sealing, both high-purity gas is polluted, the specified safety dumping force value of adhesion of long duration is not opened; Can not protect the safe in utilization of the person and equipment, satisfy not the requirement of development of modern scientific technology.
Summary of the invention:
For solving the defective of existing gas regulator safe discharge equipment; A kind of gas regulator safe discharge equipment of the present invention; The technical scheme that adopts is: design a kind of safety dumping valve, safety dumping valve front end face is identical with the vent port diameter, and the centre is that deepening is domatic backward for polygon and safety dumping valve front end face; Have groove to embed fluororubber O shape circle on domatic, safety dumping valve rear end is placed spring and accent silk, is closed silk.Safety valve body directly is connected with the gas regulator main body; Bottom being connected, the gas regulator main body is taper; Angle of taper and safety dumping valve the front end face domatic angle of deepening backward match, and in order safety valve body directly are connected with the gas regulator main body, are taper bottom the gas regulator main body is connected; Angle of taper and safety dumping valve the front end face domatic angle of deepening backward match; Safety dumping valve front end face is identical with the vent port diameter, and deepening is domatic backward for safety dumping valve front end face, has on domatic groove to embed fluororubber O shape circle; The centre is a polygon, and the rear end is placed and closed tight with closing silk after spring reinstalls the required force value of accent silk adjustment.
Gas regulator safe discharge equipment of the present invention designs a kind of safety dumping valve, safety dumping valve front end face is identical with the vent port diameter, has avoided contacting of fluororubber O shape circle and high-purity gas.
Gas regulator safe discharge equipment of the present invention designs a kind of safety dumping valve, is that the exhaust of having led is unobstructed for its effect of polygon in the middle of the safety dumping valve.
Gas regulator safe discharge equipment of the present invention; Design a kind of safety dumping valve; Deepening is domatic backward for safety dumping valve front end face, and having on domatic groove to embed the fluororubber O shape circle bottom that is connected with the gas regulator main body is taper, and angle of taper and safety dumping valve the front end face domatic angle of deepening backward match; Highly sensitive, of long duration also can the specified force value of safety dumping.
Gas regulator safe discharge equipment of the present invention, compact conformation is simple, and office of design portion is rationally unique; Volume is little, and is highly sensitive, deducted many unreasonable structures and link; Reduce cost, increase work efficiency, the effective protection person and equipment safe in utilization.
Gas regulator safe discharge equipment of the present invention comprises: 1, safety valve body 2, fluororubber O shape circle 3, safety dumping valve 4, spring 5, transfer silk 6, close silk 7, gas regulator
Description of drawings
Below in conjunction with accompanying drawing gas regulator safe discharge equipment of the present invention is done further explain:
Fig. 1 is a gas regulator safe discharge equipment structural representation of the present invention;
Fig. 2 is a gas regulator safe discharge equipment parts synoptic diagram of the present invention;
In Fig. 1, Fig. 2,1, safety valve body 2, fluororubber O shape circle 3, safety dumping valve 4, spring 5, transfer silk 6, close silk 7, gas regulator
Embodiment:
Gas regulator safe discharge equipment of the present invention, metal parts is selected high-quality stainless steel and brass material for use, and non-metal workpiece is selected for use and the medium nonpollution material of chemically reactive not.
Gas regulator safe discharge equipment of the present invention; Installation step is referring to Fig. 1, Fig. 2; At first safety valve body (1) being screwed in gas regulator main body (7) locates; Then fluororubber O shape circle (2) is embedded in the domatic groove of safety dumping valve (3), in order safety dumping valve (3), spring (4) are packed in the safety valve body (1), reinstall and close tightly with closing thread (6) after transferring the required force value of silk (5) adjustment.
Gas regulator safe discharge equipment of the present invention, pollution-free adhesion guarantee that 2 times specified top hole pressure safety dumping force value and emission flow are more than or equal to rated flow.
Through the structure and the manufacturing approach of the above gas regulator safe discharge equipment of the present invention, the defective of the existing gas regulator safe discharge equipment of effective solution, having embodied gas regulator safe discharge equipment of the present invention, to have a compact conformation simple; Office of design portion is rationally unique, and volume is little, and is highly sensitive; Deducted many unreasonable structures and link, economized on resources, reduced cost; Increase work efficiency; The effective protection person and equipment safe in utilization can be satisfied the demand of modern high technology development, creative and novelty fully.
