Description
Technical field
The utility model belongs to gas transmission and distribution equipment technical field, more particularly to a kind of family low pressure voltage-stabilizing voltage regulator.
Background technology
Natural gas needs to use Low Pressure Gas Network pressure regulator during the civilian family of terminal is transported to.Current family is with surely
Pressure pressure regulator includes upper casing, lower casing, and lower casing is provided with import, outlet, set in lower casing valve port, the homophony epithelium with pallet,
Valve rod, valve rod upper end is connected with the homophony epithelium with pallet, and valve rod lower end is provided with the regulating valve seat matched with valve port,
Upper casing is provided with cap, regulation is female, adjust the pull bar that spring is connected with valve rod.Pressure is higher in house lead in, and gas-cooker is not
Easily in the case of igniting, low pressure voltage-stabilizing voltage regulator reduces pressure and stablize and holds in ignitable pressure limit in gas-cooker.
Elevated pressures are entered by pressure regulator import, by valve port, reach outlet, by the air pressure of valve port to homophony epithelium and regulation spring
Maintain an equal level the active force for weighing, and homophony epithelium is up and down, and valve rod and regulating valve seat that drive is connected with homophony epithelium control valve port
The distance between with regulating valve seat, reach and allow effect of the outlet pressure stability in the range of certain pressure.Adjusted with voltage stabilizing at this family
The precision of voltage regulation of depressor is relatively low, there is potential safety hazard in the case of downstream pressure leakage out of control.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of precision of voltage regulation is high, safety coefficient is high family with low
Pressure voltage-stabilizing voltage regulator.
In order to solve the above technical problems, the technical solution adopted in the utility model is：Including upper casing, lower casing, lower casing is set
There are import, outlet, valve port, the homophony epithelium with pallet, valve rod, valve rod upper end and the homophony skin with pallet are set in lower casing
Film is connected, and valve rod lower end is provided with the regulating valve seat matched with valve port, upper casing be provided with cap, female regulation, regulation spring,
The pull bar being connected with valve rod, is provided with the self-closing valve seat that epithelium underlay, balance film and valve port match on described valve rod,
Balance film baffle plate fixes balance film with lower shell phase, and valve rod is provided with feedback hole, and the outlet of feedback hole lower end is in stem bottom, feedback
Hole upper end outlet is between homophony epithelium and balance film.
Its additional technical feature is：The pressure regulation area of the balance film matches with the pressure regulation area of regulating valve seat.
Family provided by the utility model low pressure voltage-stabilizing voltage regulator, natural gas is entered by pressure regulator import, to regulating valve
When seat acts pressure, opposite effect power, the bearing area of balance film and the pressure-bearing of regulating valve seat also are produced to balance film
Area is identical, therefore the active force being subject to is also identical, because balance film is connected with regulating valve seat by valve rod, two kinds insist on it is flat
Weighing apparatus.Outlet pressure passes through feedback hole between homophony epithelium and balance film, to homophony epithelium and regulation acting force of the spring, homophony skin
Film is up and down, valve rod and regulating valve seat that drive is connected with homophony epithelium, controls the distance between valve port and regulating valve seat,
In required pressure limit, balance film causes that the precision of voltage regulation is greatly improved to control outlet pressure stabilization.After low pressure pressure regulator
Face pipeline breaking, in the case of causing a large amount of natural gas leakings, the pressure of homophony epithelium cavity of resorption reduces, the modulated bullet of homophony epithelium
The active force of spring declines, and related valve rod declines, and the self-closing valve seat on valve rod synchronously declines, and self-closing valve seat is buckled on valve port, cuts off
Into the natural gas of valve port, it is to avoid the harm that a large amount of leakage natural gases are caused, safe sequel is eliminated.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model family low pressure voltage-stabilizing voltage regulator.
Specific embodiment
The structure and operation principle to the utility model family low pressure voltage-stabilizing voltage regulator are done further in detail below in conjunction with the accompanying drawings
Describe in detail bright.
As shown in figure 1, the utility model family includes upper casing 1, lower casing 2 with low pressure voltage-stabilizing voltage regulator, lower casing 2 is provided with import
3rd, setting valve port 5, the homophony epithelium 7 with pallet 6, valve rod 8 in 4, lower casing 2, the upper end of valve rod 8 and the master with pallet 6 are exported
Naughty film 7 is connected, and the lower end of valve rod 8 is provided with the regulating valve seat 9 matched with valve port 5, and upper casing 1 is provided with cap 10, regulation
Female 11, the pull bar 13 that regulation spring 12 is connected with valve rod 8, is provided with epithelium underlay 14, balance film 15 and valve port on valve rod 8
The 5 self-closing valve seats 16 for matching, balance film baffle plate 17 mutually fixes balance film 15 with lower casing 2, and valve rod 8 is provided with feedback hole 18,
The lower end of feedback hole 18 is exported in the bottom of valve rod 8, and the upper end outlet of feedback hole 18 is between homophony epithelium 7 and balance film 15.
Family provided by the utility model low pressure voltage-stabilizing voltage regulator, natural gas is entered by pressure regulator import 3, to regulating valve
When seat 9 acts pressure, opposite effect power, the bearing area and regulating valve seat 9 of balance film 15 also are produced to balance film 15
Bearing area it is identical, therefore the active force being subject to is also identical, because balance film 15 is connected with regulating valve seat 9 by valve rod 8, two
Plant and insist on balance.Export 4 pressure to be arrived between homophony epithelium 7 and balance film 15 by feedback hole 18, to homophony epithelium 7 and regulation bullet
The active force of spring 12, homophony epithelium 7 is up and down, valve rod 8 and regulating valve seat 9 that drive is connected with homophony epithelium 7, controls valve port
The distance between 5 and regulating valve seat 9, in required pressure limit, balance film 15 causes voltage stabilizing essence to control 4 pressure stabilitys of outlet
Degree is greatly improved.The pipeline breaking behind low pressure pressure regulator, in the case of causing a large amount of natural gas leakings, the cavity of resorption of homophony epithelium 7
Pressure reduce, the active force of the modulated spring 12 of homophony epithelium 7 declines, and related valve rod 8 declines, the self-closing valve seat on valve rod 8
16 it is synchronous decline, self-closing valve seat 16 is buckled on valve port 5, cut-out enters the natural gas of valve port 5, it is to avoid a large amount of leakage natural gases are made
Into harm, eliminate safe sequel.
Low pressure voltage-stabilizing voltage regulator in family provided by the utility model is not limited only to said structure, as long as employing this practicality
The various improvement that novel method is conceived and technical scheme is carried out, or it is not improved that design of the present utility model and technical scheme is straight
Scoop out for other occasions, in protection domain of the present utility model.
