Description
Technical field
The utility model is related to the pressure regulator on a kind of gas medium conveyance conduit, especially a kind of Horizontal gas pressure regulation
Device.
Background technology
Gas pressure regulator, governor is commonly called as gas pressure-reducing valve, is the restriction orifice size by changing pressure regulator automatically, so that will
System pressure is reduced to some scope, while must also being fulfilled for the equipment of the traffic requirement in downstream.It is generally divided into direct acting type
With two kinds of indirect acting type.When downstream user is without traffic demand, pressure regulator valve element reduces passage to limit stream close to valve port
Amount.When downstream flow increase, valve element increases its opening degree away from valve port, increases flow.From the viewpoint of hydrodynamics,
Pressure regulator is the restricting element that a local resistance can change, i.e., by changing orifice size, make the kinetic energy of flow velocity and fluid
Change, the different pressure losses are caused, so as to reach the purpose of decompression.Then by control system (mainly by main film and master
Spring is constituted) (refer mainly to be connected the main valve stem and connected lever, valve rod, valve element, restriction of diaphragm with regulating system
Deng) regulation, downstream pressure is maintained at a metastable value.
Horizontal gas pressure regulator introduces the design of lever mostly, and lever has certain lever ratio, the presence of lever ratio
Virtually expand the power that gas pressure is acted on diaphragm.The change of lever ratio affects the precision of voltage regulation and the closing of pressure regulator
Pressure rating.In the case where installing balanced valve, lever ratio is bigger, and it is bigger that the power on diaphragm is extended, and acts on valve seat
Power is also bigger, and closing performance is better, but the movement travel of diaphragm is also expanded accordingly simultaneously, and the decrement of spring is on diaphragm
Change is also bigger during lower motion, causes the expansion of spring effect, the reduction of the pressure regulator precision of voltage regulation.Lever ratio is smaller.Conversely, not
In the case of installing balanced valve, lever ratio can then offset influence of the inlet pressure to outlet pressure, can also be carried in precision aspect
It is high.In the application, the precision of voltage regulation or closing presure grade are abandoned naturally.This is clearly inflexible for changeable operating mode.
For some gas supplies business, the possible precision of voltage regulation is that they require, but uses angle from the equipment in some chemical plant
For degree, such as burner, it is possible to it is required that closing presure grade is better.For this actual conditions, a kind of spirit of design
The structure that reply operating mode living needs is necessary.
The content of the invention
The utility model is for deficiency of the prior art there is provided a kind of adjustable lever than structure pressure regulator, this practicality
It is new tackle different operating modes when with very strong flexibility, the lever that different lever ratios can be changed according to actual needs can
To reach the precision of voltage regulation and closing presure purpose of regulation pressure regulator, conventional pressure regulator lever ratio is solved unadjustable in different works
The problem of adapting to new not good under condition.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of adjustable lever

In above-mentioned technical proposal, it is preferred that described lever includes shank, described shank, which is rotated, is provided with connecting pole,
The described flexible sheet of described connecting pole connection.
In above-mentioned technical proposal, it is preferred that described lever includes crank head, and described regulating valve includes valve seat, described
Valve seat on be provided with the balance valve rod being connected with the crank head and the valve element being engaged with the valve port.
In above-mentioned technical proposal, it is preferred that described shank passes through dismountable mode connects for screw with the connecting pole.
In above-mentioned technical proposal, it is preferred that be provided with balancing spring on described balance valve rod.
The utility model is a kind of gas pressure regulator, governor, and primary structure is a kind of pressure regulator of Horizontal band lever, compared to existing
Horizontal pressure regulator, be provided with lever platform in the pressure regulating cavity of gas pressure regulator, governor of the present utility model, set on lever platform
There are several lever rotation framves, each lever rotation frame can individually lay different levers so that gas pressure regulator, governor can be with
Obtain the different precision of voltage regulations and closing presure.Specifically, when the supply gas pressure of station changes, avoid the need for again with
Change gas pressure regulator, governor, it is only necessary to which the lever that change is arranged on lever platform is with regard to that can allow gas pressure regulator, governor to obtain new pressure regulation pressure
Power.
Compared with prior art, the beneficial effects of the utility model are：The utility model has when tackling different operating modes
Very strong flexibility, the lever of different lever ratios can be changed according to actual needs can just reach the voltage stabilizing essence of regulation pressure regulator
