Abstract
The utility model discloses a kind of flow and the constant temperature valve core of the linear change of pressure difference, including insert body and be arranged in the middle part of the insert body and with the valve rod of its close-fitting, it is characterized in that, the insert body bottom is provided with makes valve flow and the linear change of pressure difference with the linear curve of valve core of Low Pressure Drop Ratio, the curve of valve core.The utility model has preferably linear adjustability and reduces the pressure drop before and after valve, reduces valve operation energy consumption and extends valve element service life.
Description
Technical field
It the utility model is related to valve field, more particularly to a kind of flow and the constant temperature valve core of the linear change of pressure difference.
Background technology
At present, the curve of known constant temperature valve core is mostly inverted-triangular or rectangle type structure, equipped with this valve element
Valve has fast opening characteristic, and flow just reaches 100% when valve opening reaches 20% of total kilometres or so, remainder 80% or so
Stroke do not play a role.Above-mentioned valve is run under the operating mode of small guide vane for a long time, very big to valve element infringement, and to flow
Control ability is also poor, and under identical operating condition, the service life of above two valve element is shorter, and energy consumption is larger.
How to make valve that there is preferably linear adjustability and reduce the pressure drop before and after valve, reduce valve operation energy consumption and prolong
Long valve element service life is the important directions that everybody studies.
The content of the invention
The utility model is mainly to solve technical problem present in above-mentioned prior art, there is provided a kind of flow and pressure difference into
The constant temperature valve core of linear change, solves that prior art regulation performance is poor, and service life is short, and operation energy consumption is high lacks
Point, make each valve that there is preferable controllability, and its longer service life, reduce operating cost.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of flow and pressure
The constant temperature valve core of the linear change of difference, including insert body and be arranged in the middle part of the insert body and with the valve of its close-fitting
Bar, the insert body bottom are provided with the linear curve of valve core of Low Pressure Drop Ratio, the curve of valve core make valve flow with
The linear change of pressure difference.
Preferably, the insert body top is furnished with pad with valve rod pine.
Preferably, the jump ring of the upper-lower position to setting-up piece is housed on the pad in valve rod.
The utility model has the advantage that：It is simple in construction, easy for installation, there is preferably linear adjustability and reduction
Pressure drop before and after valve, reduce valve operation energy consumption and extend valve element service life.

In figure：1st, valve seat；2nd, curve of valve core；3rd, insert body；4th, pad；5th, jump ring；6th, valve rod.
Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment：A kind of flow and the constant temperature valve core of the linear change of pressure difference, as shown in Figure 1-2, including insert body 3
With be arranged on the middle part of the insert body 3 and with the valve rod 6 of its close-fitting, the top of insert body 3 is with the pine of valve rod 6 equipped with pad
Piece 4, the jump ring 5 of the upper-lower position to setting-up piece 4, the bottom of insert body 3 are housed in valve rod 6 on the pad 4
Be provided with makes valve flow and the linear change of pressure difference with the linear curve of valve core 2 of Low Pressure Drop Ratio, the curve of valve core 2.
The insert body 3 is arranged on valve seat 1, and the bottom of the valve rod 6 is fixed on the middle part of the valve seat 1.
Finally it is pointed out that above example is only the more representational example of the utility model.Obviously, this practicality is new
Type is not limited to above-described embodiment, can also there is many deformations.Every foundation the technical essence of the utility model is to above example
Any simple modification, equivalent change and modification made, it is considered as belonging to the scope of protection of the utility model.
