Abstract
The invention discloses a gas pressure regulator which comprises a valve body and a pilot valve, wherein a gas inlet channel and a gas outlet channel as well as a valve rod are respectively arranged in the valve body, the lower end of the valve rod is arranged between the gas inlet channel and the gas outlet channel, the gas outlet channel is connected with a gas tube, a spring is sleeved on the lower end of the valve rod, a skin membrane is arranged on the upper end of the valve rod and positioned in a cavity at the upper end of the valve body and used for dividing the cavity into an upper skin membrane cavity and a lower skin membrane cavity, the pilot valve is respectively connected with the gas inlet channel, the gas tube, the upper skin membrane cavity and the lower skin membrane cavity, a ventilating hole is arranged on the skin membrane, and the upper skin membrane cavity is communicated with the lower skin membrane cavity through the ventilating cavity. The invention has the advantage that the gas pressure regulator has lower use cost, reduces gas leakage points and is convenient for controlling flow.
Description
Technical field
The present invention relates to a kind of gas regulator, relate in particular to a kind of gas pressure regulator, governor.
Background technique
Gas pressure regulator, governor is to be used for a kind of device that other non-corrosiveness gases such as rock gas, liquefied petroleum gas (LPG), artificial coal gas, mine gas are carried out pressure regulation, and gas pressure regulator, governor is applicable to that the inlet pressure fluctuation is big, mesolow, the door station or the regional pressure regulation of big flow.Existing gas pressure regulator, governor can use needle value, has increased the gas leakage point, is difficult to control flow rate, has increased user cost.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of user cost lower, control gas pressure regulator, governor easily.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: gas pressure regulator, governor, comprise: valve body and pilot valve, gas-entered passageway is set respectively in valve body, outlet passageway and valve rod, the lower end of valve rod is provided with between gas-entered passageway and the outlet passageway, outlet passageway is connected with fuel tube, on the lower end of valve rod, be arranged with spring, the upper end of valve rod is provided with epithelium, epithelium is arranged in the cavity of valve body upper end and with cavity and is divided into epithelium epicoele and epithelium cavity of resorption, command valve respectively with gas-entered passageway, fuel tube, the epithelium epicoele is connected with the epithelium cavity of resorption, and epithelium is provided with vent, and epithelium epicoele and epithelium cavity of resorption are connected by vent.
Advantage of the present invention is: above-mentioned gas pressure regulator, governor, user cost is lower, has reduced the gas leakage point, makes things convenient for control flow rate.
Description of drawings
Fig. 1 is the sectional structure schematic representation of gas pressure regulator, governor of the present invention.
Among the figure: 1, valve body, 2, pilot valve, 3, gas-entered passageway, 4, outlet passageway, 5, valve rod, 6, fuel tube, 7, spring, 8, epithelium, 9, the epithelium epicoele, 10, the epithelium cavity of resorption, 11, vent.
Embodiment
Describe particular content of the present invention in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, gas pressure regulator, governor, comprise: valve body 1 and pilot valve 2, gas-entered passageway 3 is set respectively in valve body 1, outlet passageway 4 and valve rod 5, the lower end of valve rod 5 is provided with between gas-entered passageway 3 and the outlet passageway 4, outlet passageway 4 is connected with fuel tube 6, on the lower end of valve rod 5, be arranged with spring 7, the upper end of valve rod 5 is provided with epithelium 8, epithelium 8 is arranged in the cavity of valve body 1 upper end and with cavity and is divided into epithelium epicoele 9 and epithelium cavity of resorption 10, command valve 2 respectively with gas-entered passageway 3, fuel tube 6, epithelium epicoele 9 is connected with epithelium cavity of resorption 10, and epithelium 8 is provided with vent 11, and epithelium epicoele 9 and epithelium cavity of resorption 10 are connected by vent 11.
When above-mentioned gas pressure regulator, governor uses, when user's usefulness gas increases, the pressure of fuel tube 6 and epithelium epicoele 9 descends, make between epithelium epicoele 9 and the epithelium cavity of resorption 10 and pressure reduction occurs, valve rod 5 is moved upward, the aperture of valve is increased, make the combustion gas in the gas-entered passageway 3 add to outlet passageway 4, in fuel tube 6 and the epithelium epicoele 9, because epithelium 8 is provided with vent 11, combustion gas in the epithelium cavity of resorption 10 also can be mended as arrive in the epithelium epicoele 9 by vent 11, make epithelium epicoele 9 identical with pressure between the epithelium cavity of resorption 10, valve rod 5 also can descend and be returned to the origin-location, and the aperture of valve is reduced.
