Abstract
The invention relates to a safe pressure regulator capable of automatically shutting off upon fuel gas pressure regulation control failure and super flow leakage. The safe pressure regulator is characterized in that: a pull rod, a pull ring, a steel ball and a spring or a pressure control failure protecting component which consists of the pull rod, the pull ring and a magnetic sheet are arranged in a shell; a straight-forward shutoff system consisting of a shutoff mouth, a shutoff component, a shutoff spring and a spring cap sheet is arranged at a gas inlet; when a fuel gas pressure regulator has a pressure regulation control failure, fuel gas pressure in the shell rises, the pull rod and the pull ring are automatically separated, and the straight-forward shutoff system is shut off, so that high pressure automatic shutoff protection for the pressure regulation control failure is realized; and when fuel gas leaks with supper flow, the fuel gas pressure in the shell drops sharply, and the straight-forward shutoff system is shut off, so that the low pressure automatic shutoff protection for the fuel gas supper flow leakage is realized. The safe pressure regulator has a simple structure, high technical performance and low product cost, and is easy to manufacture, convenient to manage, safe, reliable and durable.
Description
Technical field: the present invention relates to a kind ofly prevent that the combustion gas pressure regulation is out of control and cause the automatic safety device of the ultra flow leakage of combustion gas, patented technology of the present invention to can be applicable to process pipeline gas with sebific duct accident such as come off, break protecting pipeline gas automatic protection valve behind pressure-regulating box, indoor table preceding pipeline gas automatic protection pressure governor, the indoor table, bottle gas to protect pressure governor automatically automatically.When pressure governor generation combustion gas pressure regulation flow out of control, ultra leaked contingency, device was closed automatically, cut off source of the gas, prevented the generation of gas leakage and fire explosion, improved and used gas safety.
Background technique: along with the development of society, the extensive use of new energy, combustion gas have become industry and necessary fuel energy in life; Use in the gas process the resident, various leakages are almost all arranged everyday, poison, catch fire or the generation of explosive accident, particularly out of control and flexible rubber hose comes off, breaks etc. because of the gas pressure regulator, governor pressure regulation; The poisoning that causes, catch fire or explosive accident in the majority, it is stable to have had a strong impact on social harmony, the application of patent of the present invention in domestic gas; Can prevent the generation of contingency effectively; Reduce property loss, the protection life safety is improved the quality of living.
Summary of the invention: the present invention a kind ofly can be leaked the safety protection device that can close automatically to combustion gas pressure regulation flow out of control and ultra, its by upper shell, lower shell body, elastomer diaphragm, disc, pressure spring, enable switch, connecting rod, pressure lost-control protection parts, pressure regulation mouth, handwheel, sealer, voltage regulation part and forward shutdown system form.Wherein enable switch is made up of pull-button, return spring and pull-button sleeve pipe; Forward shutdown system by the pass shut up, shut-off block and close spring and the spring cover plate constitutes; Shut-off block constitutes by closing push rod, thimble and closing glue; Voltage regulation part is made up of pressure regulation push rod, pressure regulation glue and pressure regulation bar; Pressure lost-control protection parts are made up of pull bar, draw ring, steel ball and spring.
Gaseous-pressure of the present invention automatic protection pressure governor pressure regulation lost-control protection function out of control is: when the gas pressure regulator, governor pressure regulation was out of control, the gaseous-pressure in the housing rose, and upwards promotes elastomer diaphragm; When elastomer diaphragm tension force was connected power greater than the spring of pull bar and draw ring, pull bar separated with draw ring, and the pressure regulation bar falls down; Closing under the spring action; Close glue and the pass closure of shutting up, shutdown system is forward closed, and realizes that pressure regulation high pressure out of control closes protection automatically; Ultra flow leaks automatic protection functions: when the ultra flow of combustion gas leaks; Gaseous-pressure in the housing suddenly gathers decline; The tension force of pressure spring promotes to fall under the elastomer diaphragm, is closing under the spring action, closes glue and the pass closure of shutting up; Shutdown system is forward closed, and realizes that the ultra flow of combustion gas leaks low pressure and protects automatically.The present invention is simple in structure, and technical performance is good, and product cost is low, simple for production, convenient management, safe and reliable, durable.
Description of drawings: accompanying drawing is a gaseous-pressure automatic protection pressure governor structural representation out of control.
Embodiment: with reference to accompanying drawing, gaseous-pressure of the present invention automatic protection pressure governor out of control by upper shell 1, lower shell body 10, elastomer diaphragm 8, disc 2, pressure spring 7, enable switch, connecting rod 6, pressure lost-control protection parts, pressure regulation mouth 18, handwheel 9, sealer 25, voltage regulation part and forward shutdown system constitute.Wherein install a forward shutdown system, and cooperate with pressure regulation mouth 18 and voltage regulation part at lower shell body 10 suction port ends; Installing elastomer diaphragm 8 between upper shell 1 and lower shell body 10; Elastomer diaphragm 8 upper ends installing pressure spring 7 and disc 2 match with upper shell 1; Elastomer diaphragm 8 lower ends installings pressure lost-control protection parts match with shutdown system forward; Install an enable switch in center, upper shell 1 lower end, and match with pressure lost-control protection parts through connecting rod 6.Voltage regulation part comprises pressure regulation push rod 16, pressure regulation glue 17 and pressure regulation bar 11; Enable switch comprises pull-button 3, return spring 4, pull-button sleeve pipe 5; Pressure lost-control protection parts comprise pull bar 15, draw ring 14, steel ball 12 and spring 13; Forward shutdown system comprises closing and shuts up 20, shut-off block, close spring 23 and spring cover plate 24; Shut-off block comprises closes push rod 22, thimble 19 and closes glue 21.
Gaseous-pressure of the present invention automatic protection pressure governor out of control shutdown system before use is in closed condition, during work, and the pull-button of pulling enable switch; The pass unlatching of shutting up, combustion gas gets in the housing, and elastomer diaphragm is under the effect of gaseous-pressure; Upwards heave, drive the shut-off block motion, close glue and shut up with the pass and separate through the pressure regulation bar; When the tension force of elastomer diaphragm equated with the tension force of pressure spring, the gaseous-pressure in the housing was in metastable state, its proper functioning; When the gas pressure regulator, governor pressure regulation was out of control, the gaseous-pressure in the housing rose, and upwards promotes elastomer diaphragm; When elastomer diaphragm tension force was connected power greater than the spring of pull bar and draw ring or magnetic sheet, pull bar separated with draw ring, and the pressure regulation bar falls down; Closing under the spring action; Close glue and the pass closure of shutting up, shutdown system is forward closed, and realizes that pressure regulation high pressure out of control closes protection automatically; When the ultra flow of combustion gas leaked, the gaseous-pressure in the housing suddenly gathered decline, and the tension force of pressure spring promotes to fall under the elastomer diaphragm; Closing under the spring action; Close glue and the pass closure of shutting up, shutdown system is forward closed, and realizes that the ultra flow leakage of combustion gas low pressure protects automatically.
