Abstract
The utility model relates to a valve core of a gas flow control electric governing valve, which comprises a ball-shaped valve body (1), wherein a flow regulation orifice (2) is arranged in the valve body (1), a control pin installation hole (3) is arranged outside the valve body (1), and through holes (4) which are threaded mutually are also arranged on the valve body (1) and are located on two sides of the valve core on the path direction when the valve core is in the close state. The valve core of the gas flow control electric governing valve guarantees small flow quantitative control, prolongs the service life of the valve, and lengthens the replacement period, and saves the cost under the condition that the valve can not guarantee the precision, the valve has the advantages that the structure is simple, the installation is convenient, the whole service life of the valve is prolonged, and the control precision is improved, and the defects that a gas control valve controls unstably when in small flow are fetched up.
Description
Technical field
The utility model belongs to the gas flow control valve field, particularly relates to a kind of gas flow regulating and controlling valve core.
Background technique
Present most of gas flow control all uses electric control valve and control system combines, comprising " V " type spool and early stage " 0 " type spool, at the initial stage of dropping into and since valve precision higher, meeting the requirements aspect the flow continuous control.
Electric control valve uses " V " type through hole spool, and early stage manhole can both satisfy the automatic control of flow, " V " type is higher aspect precision, but because we select the scope of flow bigger, but require the relatively little flow of control, for example oxygen flow requires control range at 0 ~ 1600m3/H, there is a small flow need keep 100 ~ 150m3/H, at this moment oscillatory instability will appear in regulating system, even situation about a little while opening occurs closing for a moment, adopts segmentation control can not reach requirement, the influence that descended by operating mode and service precision, low discharge is difficult to stable control, is just kept thereby need the short period more to renew valve, and cost of investment is bigger.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of gas flow control motorized adjustment valve core, to solve in the prior art the inconvenient defective of accurate control to small flow.
A kind of gas flow control motorized adjustment valve core, include the valve body (1) of a ball-type, the inside of described valve body (1) has Flow-rate adjustment hole (2), the outside of valve body (1) has control pin mounting hole (3), also have through through hole (4) on the described valve body (1), the both sides of the latus rectum direction spool when being positioned at the spool closed condition.
Described Flow-rate adjustment hole (2) is V-type or O type.
Described control pin mounting hole (3) is a rectangular.
Beneficial effect
The utility model can not guarantee under the situation of precision at valve, the assurance small flow is quantitatively controlled, prolonged the working life of valve, extended the cycle of changing, saved cost, have lengthening and the lifting of control accuracy in working life simple in structure, easy for installation, that valve is whole, remedied gas control valve and when small flow, controlled unsettled shortcoming.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
A kind of gas flow control motorized adjustment valve core, include the valve body 1 of a ball-type, the inside of described valve body 1 has V-type Flow-rate adjustment hole 2, the outside of valve body 1 has rectangular control pin mounting hole 3, also have through through hole 4 on the described valve body 1, the both sides of the latus rectum direction spool when being positioned at the spool closed condition.
A kind of gas flow control motorized adjustment valve core, include the valve body 1 of a ball-type, the inside of described valve body 1 has O type Flow-rate adjustment hole 2, the outside of valve body 1 has rectangular control pin mounting hole 3, also have through through hole 4 on the described valve body 1, the both sides of the latus rectum direction spool when being positioned at the spool closed condition.
We have selected radially two through holes of buttoned-up status, the size of having calculated the aperture according to the demand of low discharge size is when valve control changes from the high flow capacity to the low discharge, because the sensitivity of valve is subjected to the effect of inertia that influences of service time to become big, valve can close extremely quickly, but because the existence of through hole 4, guaranteed the fixing output of low discharge, just can realize by another rill metered valve segmentation control then.
Claims (3)
1. a gas flow is controlled the motorized adjustment valve core, include the valve body (1) of a ball-type, the inside of described valve body (1) has Flow-rate adjustment hole (2), the outside of valve body (1) has control pin mounting hole (3), it is characterized in that: also have through through hole (4) on the described valve body (1), the both sides of the latus rectum direction spool when being positioned at the spool closed condition.
2. gas flow control motorized adjustment valve core as claimed in claim 1, it is characterized in that: described Flow-rate adjustment hole (2) is V-type or O type.
3. gas flow control motorized adjustment valve core as claimed in claim 1 or 2, it is characterized in that: described control pin mounting hole (3) is rectangular.
