Description
Technical field
The utility model belongs to the gas transmission and distribution equipment technical field, relates in particular to a kind of cut-out pressure regulation integrated gas pressure governor.
Background technique
Gas pressure regulator, governor is to be specially adapted in the gas transmission and distribution system being widely used in the gas transmission and distribution engineering as the combustion gas voltage adjusting device of pressure regulation, voltage stabilizing.Its effect is to regulate gas outlet pressure automatically, makes its step-down equipment that is stabilized in a certain pressure range, satisfies the force value of customer requirements by pressure regulation, voltage stabilizing, satisfies usage requirement.The direct acting type pressure governor is a kind of self-powering type pressure governor, and it is to utilize gas ductwork self pressure to regulate a kind of direct acting type decompression of its outlet pressure, pressure stabilizing device automatically.Be widely used between gas transmission and distribution network and the user's gas pipeline, himself is not with cut-off valve, is mainly used in regional pressure regulation and industrial user's pressure regulation.
Current, in the process of China's gas cause fast development, government and civil gas management department are when accelerating the pipeline network of fuel gas in city construction, take to make full use of existing gas ductwork, increase the transmission ﹠ distribution ability of the original gas ductwork in city with the way that improves pipe network running pressure, alleviate the contradiction that urban infrastructure for many years lags behind economic development and people's lives needs relatively, be acknowledged as a kind of comparatively feasible scheme, therefore guaranteeing under the stable prerequisite of gas pressure regulator, governor outlet pressure, improve the inlet pressure accommodation of gas pressure regulator, governor as far as possible, improve the safety coefficient of gas pressure regulator, governor, be present gas pressure regulator, governor problem demanding prompt solution technically as far as possible.The direct acting type pressure governor of current production can not meet the demands.
The model utility content
Problem to be solved in the utility model a kind ofly can provide the cut-out pressure regulation integrated gas pressure governor that has safety guarantee function when stablizing supply gas pressure with regard to providing to the user.
For addressing the above problem, the technical solution adopted in the utility model is: comprise having suction port, the air outlet, valve port, regulate the housing in chamber, be provided with diaphragm in the adjusting chamber and be divided into epicoele and cavity of resorption, be provided with pallet in the epicoele, Regulation spring and adjusting nut, cavity of resorption is connected with the air outlet by the signal pipe, pallet with pass cavity of resorption, valve port, the adjustable lever that the bottom has modulating valve is connected, modulating valve and valve port bottom connection are near, be provided with the balance pallet that the bottom is connected with the epithelium cavity in the described housing, the epithelium cavity bottom is connected with the cut-out spring, connect plain cushion and cut-off valve, cut-off valve and valve port top are close, housing is provided with the cut-out assembly that is connected with the air outlet by the signal feed back pipe, cuts off the assembly front end by cutting off bar and being connected plain cushion and contacting.
A kind of cut-out pressure regulation integrated gas pressure governor provided by the utility model, pressure governor is inner to adopt the design of twolip valve port, is modulating valve below the valve port, is cut-off valve above the valve port, has realized that on overall structure the cut-out pressure regulation is integrated.Just in case when the superpressure of user security taking place to jeopardize supplying gas accident, can in time cut off the contact between gas transmission and distribution network and the user's gas pipeline, guarantee combustion gas user's the security of the lives and property.
Pressure governor in proper functioning, adjustment process is: air outlet pressure enters the diaphragm cavity of resorption through the signal pipe, and the power that makes progress in the diaphragm cavity of resorption and epicoele Regulation spring are set downward power and reached balance, and outlet is in normal open mode below the valve port.When air outlet pressure raises, the signal pipe in time feeds back to the diaphragm cavity of resorption with the outlet pressure signal, when the power that the diaphragm cavity of resorption makes progress is set downward power greater than diaphragm epicoele Regulation spring, diaphragm drives pallet and moves up, pallet moves up and drives adjustable lever and move up, and the modulating valve of adjustable lever bottom moves up, and exports below the valve port to reduce, make air outlet pressure reduce to recover normal value, thereby reach the purpose of decompression, voltage stabilizing.When air outlet pressure reduces, the signal pipe in time feeds back to the diaphragm cavity of resorption with the outlet pressure signal, when the power that the diaphragm cavity of resorption makes progress is set downward power less than diaphragm epicoele Regulation spring, diaphragm drives pallet and moves down, pallet moves down and drives adjustable lever and move down, and the modulating valve of adjustable lever bottom moves down, and outlet increases below the valve port, air outlet pressure is increased recover normal value, thereby reach the purpose of pressurization, voltage stabilizing.This pressure governor can be regulated the size of its outlet pressure automatically, is suitable for any inlet pressure ranges, does not need to change valve port get final product pressure regulation, voltage stabilizing under the different pressures situation.
Pressure governor in proper functioning, cutting-off process is: air outlet pressure is delivered to the cut-out assembly through the signal feed back pipe, cuts off bar and will connect the plain cushion braking, and outlet is in normal open mode above the valve port.When the combustion gas voltage adjusting device breaks down, air outlet pressure raises, the signal feed back pipe in time feeds back to the cut-out assembly with the outlet pressure signal, cutting off assembly makes the cut-out bar break away from the connection plain cushion, cut-off valve is cutting off under the spring action, thereby export above the cut-out valve port, reach the effect of cutting off source of the gas.This combustion gas high-pressure shut-off excess pressure cutout is safe and reliable, and it is sensitive to cut off response, cuts off the precision height.
