Abstract
The utility model relates to a direct-acting type gas regulator, which is a device turning the gas with the higher pressure in a gas transmission and distribution system to the gas with the lower pressure and causing the lower pressure to be stabilize in the range of the certain requirement. An inlet of a main pressure regulator is connected with a high pressure gas pipeline, and an inlet is connected with a low pressure gas pipeline. The utility model is characterized in that the low pressure gas pipeline is communicated with a balancer lower cavity below a balancer leather diaphragm of which the center is connected with a valve rod of the main pressure regulator by a lever of which the fulcrum is arranged on a top cover of the main pressure regulator and is opposite to the position of the balancer, the lever above the balancer is pressed with a balancing weight. The utility model has the advantages that compared with the indirect-acting type gas pressure regulator, the structure of the direct-acting type gas regulator is simpler, the volume and the occupation area are reduced, the operation and the maintenance are easy, and the operation is safer, more reliable and stable; moreover, compared with the existing direct-acting type gas regulator and the indirect-acting type gas regulator, the cost of the direct-acting type gas regulator is reduced. The utility model is more suitable for popularization and application.
Description
(1) technical field
The utility model relates to a kind of combustion gas that the combustion gas of elevated pressures decompression is become lower pressure in gas transmission and distribution system, and makes its lower pressure be stabilized in equipment in certain claimed range, is a kind of direct acting type gas pressure regulator, governor specifically.
(2) background technique
According to the principle difference of gas pressure regulator, governor equipment, be divided into two kinds of direct acting type gas pressure regulator, governor and indirect acting type fuel gas pressure governors.The direct acting type gas pressure regulator, governor only relies on the variation of the pressure governor outlet pressure that sensing element (diaphragm or film) experienced to come mobile regulating valve to carry out the adjusting of outlet pressure, makes outlet pressure remain on fluctuation in the pressure range of permission.(flow is greater than 500Nm for the direct acting type gas pressure regulator, governor of direct acting type gas pressure regulator, governor, particularly big flow
3/ h) be the domestic combustion gas voltage adjusting device that just occurs after introducing external product the nineties, as to introduce the single channel flow that Italy flies gas-fired equipment difficult to understand company be 3000Nm
3The voltage adjusting device of/h, introduce the big flow combustion gas voltage adjusting device of U.S. Fisher company and French Schlumberger company, the general spring direct acting type gas pressure regulator, governor that adopts, its cost is higher, a general main frame price is ten thousand yuan of 6-8, at present, domesticly still can not produce the direct acting type gas pressure regulator, governor suitable with these imported product quality.In the indirect acting type fuel gas pressure governor, the variation of gas outlet pressure at first makes its operating mechanism action, connects combustion gas, thereby makes the action of combustion gas main voltage regulator modulating valve, makes its outlet pressure remain on the interior fluctuation of pressure range of permission.Reynolds formula gas pressure regulator, governor is exactly typical indirect acting type fuel gas pressure governor.Shortcoming is a complex structure, and floor space is big, and the maintaining workload is big, and high to the degree of purification requirement of combustion gas, operating technology requires high, easily forms medium pressure supply sometimes, and accident causes casualties.
(3) summary of the invention
The utility model purpose is to overcome the shortcoming in the above-mentioned technology, a kind of direct acting type gas pressure regulator, governor is proposed, make it relatively simple for structure, reduce volume and floor space, Operation and maintenance easily, run more secure, reliable, stablize, and all reduce cost than existing direct acting type gas pressure regulator, governor and indirect acting type fuel gas pressure governor.
The utility model purpose is realized by following technological scheme: this direct acting type gas pressure regulator, governor, the import of its main voltage regulator is connected with the high pressure air pipeline, outlet is connected with the low pressure gas pipeline, it is characterized in that the balace weight cavity of resorption of low pressure gas pipeline below the balace weight epithelium was communicated with by connecting tube, balace weight epithelium center is connected by lever with the valve rod of main voltage regulator, the fulcrum of lever with the balace weight position opposite, is pressed with balancing weight on the lever of balace weight top on the main voltage regulator body.
The diameter of balace weight is 2-8 a times of main voltage regulator diameter, can guarantee to regulate sensitive, accurate.
Main voltage regulator is the structure of single valve mouth or bivalve mouth, all can be used in the direct acting type gas pressure regulator, governor, regulates in the gas transmission and distribution system combustion gas that the combustion gas decompression of elevated pressures is become lower pressure, and its lower pressure is stabilized in certain claimed range
The main voltage regulator valve rod is main voltage regulator valve rod 2-8 times to the balance pivot horizontal equivalent to the horizontal equivalent at balace weight epithelium center.
The working principle of direct acting type gas pressure regulator, governor is: when the combustion gas user begins promptly to begin load is arranged with gas, the main voltage regulator outlet is that gaseous-pressure reduces gradually in the low pressure gas pipeline, low-pressure fuel gas pressure also reduces gradually in the balace weight cavity of resorption below the balace weight epithelium, like this, the downward gravity of balancing weight is just greater than the active force that the balace weight epithelium makes progress that acts on that is produced by the gaseous-pressure effect, thereby cause the balace weight epithelium to move downward, by the leverage that is connected, the main voltage regulator spool is also moved downward, the spool of main voltage regulator and the open degree of valve port are increased, thereby increase the supply flow of low-pressure fuel gas, its pressure is raise.When the load increase, the spool of main voltage regulator and the open degree of valve port just increase.When the user closes with the gas utensil gradually, be that the combustion gas customer charge is when reducing gradually, the action of main voltage regulator is just in time opposite: the main voltage regulator outlet is that gaseous-pressure raises gradually in the low pressure gas pipeline, low-pressure fuel gas pressure also raises gradually in the balace weight cavity of resorption below the balace weight epithelium, like this, the downward gravity of balancing weight is just less than the active force that the balace weight epithelium makes progress that acts on that is produced by the gaseous-pressure effect, thereby cause the balace weight epithelium to move upward, by the leverage that is connected, the main voltage regulator spool is also moved upward, the spool of main voltage regulator and the open degree of valve port are reduced, thereby reduce the supply flow of low-pressure fuel gas, to keep pressure stability in the low pressure gas pipeline.When the gas appliance Close All is a customer charge when being zero, the low-pressure fuel gas pressure in the low pressure gas pipeline rises to some extent, and the balace weight epithelium is with stressed rising, and by leverage, spool also moves up, and causes the spool of main voltage regulator and valve port to be closed fully.At this moment, the gas flow that flows in the low pressure gas pipeline is zero, keeps the pressure in the low pressure gas pipeline no longer to raise, and remains unchanged.
The utility model advantage is that structure is simpler than indirect acting type fuel gas pressure governor, volume and floor space have been reduced, Operation and maintenance easily, run more secure, reliable, stablize, and all reduce cost than existing direct acting type gas pressure regulator, governor and indirect acting type fuel gas pressure governor, be more suitable in applying.
