Abstract
The utility model belongs to gas transmission and distribution equipment technical field, discloses a kind of gas pressure regulator, governor composite film.It is mainly characterized in that:Including diaphragm, the edge of the diaphragm is provided with O-ring seal, and O-ring seal is connected as a single entity with diaphragm, and diaphragm is provided with flexible circular arc at O-ring seal.Gas pressure regulator, governor composite film provided by the utility model, when manufacturing part, the seal groove to match with O-ring seal is set at the top of lower casing.During assembling, diaphragm is covered on lower casing, O-ring seal is caught in the seal groove at the top of lower casing, is then connected upper casing, lower casing by bolt, diaphragm edge sealing greatly improves.In addition, diaphragm no longer needs punching, assembling is no longer limited by punching position, substantially increases assembly working efficiency and work quality.And flexible circular arc increases the stroke of diaphragm, the operation aperture of pressure regulator is improved, runs pressure regulator more steady, flow is bigger.
Description
Technical field
The utility model belongs to gas transmission and distribution equipment technical field, more particularly to a kind of gas pressure regulator, governor composite film.
Background technology
Natural gas needs to use gas pressure regulator, governor during terminal user is transported to.Gas pressure regulator, governor include upper casing,
Lower casing, lower casing are provided with import, outlet, valve port, homophony epithelium, valve rod with pallet, valve rod upper end and band are set in lower casing
The epithelium for having pallet is connected, and epithelium is arranged between upper casing, lower casing, and valve rod lower end is provided with the regulating valve to match with valve port
Seat, upper casing are provided with cap, regulation mother, regulation spring, the pull bar being connected with valve rod.Pressure is higher in house lead in, combustion gas
In the case that stove is not easy igniting, gas pressure regulator, governor reduces pressure and stably held in gas-cooker in ignitable pressure limit.
Elevated pressures are entered by pressure regulator import, by valve port, reach outlet, and epithelium and regulation spring are maintained an equal level by the air pressure of valve port
The active force of weighing apparatus, epithelium is up and down, drives the valve rod and regulating valve seat that are connected with epithelium, control valve port and regulating valve seat it
Between distance, reach and allow effect of the outlet pressure stability in the range of certain pressure.The epithelium of this gas pressure regulator, governor such as Fig. 1,2
Shown, the edge of diaphragm is provided with the punching to match with the connecting bolt of upper casing, lower casing, is limited by punching position during installation,
The position and connecting bolt for adjusting diaphragm adapt to so that assembly working is inefficient.Further, since diaphragm is very thin, diaphragm side
Edge is smooth, and diaphragm seal is poor, easily causes gas leakage.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of simple installation, assembly working efficiency high, sealing
The good gas pressure regulator, governor composite film of property.
In order to solve the above technical problems, the technical solution adopted in the utility model is:Including diaphragm, the edge of the diaphragm
O-ring seal is provided with, O-ring seal is connected as a single entity with diaphragm, and diaphragm is provided with flexible circular arc at O-ring seal.
Its additional technical feature is:The section of the O-ring seal is arch, semicircle, rectangle, bulb-type.
Gas pressure regulator, governor composite film provided by the utility model, the edge of diaphragm are provided with O-ring seal.Manufacture
During part, the seal groove to match with O-ring seal is set at the top of lower casing.During assembling, diaphragm is covered on lower casing, made O-shaped
Sealing ring is caught in the seal groove at the top of lower casing, then by upper shell cover on lower casing, is connected upper casing, lower casing by bolt.O
Type sealing ring is connected as a single entity with diaphragm, and one-shot forming is made, and after installation, diaphragm edge sealing greatly improves.In addition, film
Piece no longer needs punching, and during assembling, bolt connects upper casing, lower casing directly through diaphragm, is no longer limited by punching position,
Substantially increase assembly working efficiency and work quality.And diaphragm is provided with flexible circular arc at O-ring seal, film is increased
The stroke of piece, the operation aperture of pressure regulator is improved, run pressure regulator more steady, flow is bigger.As needed, O-ring seal
Section for arch, semicircle, rectangle, bulb-type.
Brief description of the drawings
Fig. 1 is existing chaffy structural representation;
Fig. 2 is existing chaffy top view in Fig. 1;
Fig. 3 is the structural representation of the utility model gas pressure regulator, governor composite film.
Embodiment
The utility model gas pressure regulator, governor is made further specifically of the concrete structure of composite film below in conjunction with the accompanying drawings
It is bright.
As shown in Figure 1, 2, the edge-smoothing of existing diaphragm 1, the edge of diaphragm 1 are provided with punching 2.
As shown in figure 3, the utility model gas pressure regulator, governor is provided with O-ring seal 3, O with the edge of composite film diaphragm
Type sealing ring 3 is connected as a single entity with diaphragm 1, and diaphragm 1 is provided with flexible circular arc 4 at O-ring seal 3.
Gas pressure regulator, governor composite film provided by the utility model, the edge of diaphragm 1 are provided with O-ring seal 3.System
When making part, the seal groove to match with O-ring seal 3 is set at the top of lower casing.During assembling, diaphragm 1 is covered on lower casing, made
O-ring seal 3 is caught in the seal groove at the top of lower casing, then by upper shell cover on lower casing, is connected upper casing, lower casing by bolt
Come.O-ring seal 3 is connected as a single entity with diaphragm 1, and one-shot forming is made, and after installation, diaphragm 1 is edge sealing to be greatly improved.
In addition, diaphragm 1 no longer needs punching 2, during assembling, bolt connects upper casing, lower casing directly through diaphragm 1, is no longer rushed
The position limitation of hole 2, substantially increases assembly working efficiency and work quality.And diaphragm 1 is provided with O-ring seal 3 and stretched
Contracting circular arc, the stroke of diaphragm 1 is increased, improve the operation aperture of pressure regulator, run pressure regulator more steady, flow is bigger.Root
According to needs, the section of O-ring seal 3 is arch, semicircle, rectangle, bulb-type.
Gas pressure regulator, governor provided by the utility model is not limited only to said structure with composite film, as long as employing this reality
The various improvement carried out with novel method design and technical scheme, or it is not improved by design of the present utility model and technical scheme
Other occasions are directly applied to, in the scope of protection of the utility model.
