Description
Technical field
The utility model relates to valve, relates in particular to the adjustable valve of a kind of flow.
Background technique
Valve is a kind of pipeline fittings, is applied in widely in the fluid circuit of every profession and trade, and it is to be used for changing path section and fluid flow direction, a kind of device of control conveyance fluid motion.
Flow control valve is a kind of of valve, and it is the modulating valve that changes the aperture size by the screw thread transmission that a kind of its spool is arranged in flow control valve, and it is simple in structure, and linear value is good, can bear higher pressure.Add that manually-operable is very simple, be used on many pipelines.Yet this class flow control valve can not be regulated accurately to the fluid flow by valve body.
The model utility content
The purpose of this utility model is to provide a kind of flow control valve of can fluid flow accurately regulating.
For achieving the above object, the technological scheme that the utility model adopted is such:
This flow control valve, comprise valve body, be located at the spool that has drive screw in the valve cavity, the drive screw of spool stretches out the valve body outside fixedlys connected with a handwheel, described handwheel is a ∩ shape shell-like, position near the spool drive screw on valve body is provided with along the graduated scale indicating section of spool drive screw direction sign, and the graduated range that scale instruction unit branch indicates is positioned at the handwheel lower edge along in the stroke of spool drive screw direction.
Compared with prior art, it is of the present utility model by the spool with drive screw is set in valve body, the drive screw of spool stretches out the valve body outside fixedlys connected with a handwheel, and the position near the spool drive screw on valve body is provided with along the graduated scale indicating section of spool drive screw direction sign.Like this, rotate handwheel and drive the rotation of spool drive screw, driving spool thus moves up and down along spool drive screw direction, can adjust the gap between spool and the valve outlet, thereby also just can adjust flow by the fluid of valve outlet, by the scale that is indicated on the indicated scale indicating section in handwheel lower edge, can be to regulating accurately by the fluid flow of valve body and showing.
Description of drawings
Fig. 1 is the utility model embodiment's a plan view;
Fig. 2 is a utility model embodiment's shown in Figure 1 cut-away view.
Embodiment
Describe better embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model flow control valve, comprise valve body 1, be located at the spool 3 that has drive screw 2 in valve body 1 cavity, the drive screw 2 of spool 3 is meshed with spigot nut 4 on being installed in valve body 1 and stretches out that valve body 1 is outside fixedlys connected with a handwheel 5, described handwheel is a ∩ shape shell-like, position near spool drive screw 2 on valve body 1 is provided with along the graduated scale indicating section 6 of spool drive screw direction sign, and the graduated range that scale indicating section 6 is indicated is positioned at handwheel 5 lower edges along in the stroke of spool drive screw direction.After measuring in advance according to fluid flow, this scale indicates in advance, rotate described handwheel 5, the every rising in the lower edge of handwheel 5 or the scale that descends, expression has the fluid of definite flow to flow out valve outlet, when handwheel 5 stops the rotation, the flow through flow of valve body of the scale that its lower edge is indicated, i.e. expression can be realized digital regulated to flow like this.
For the ease of installation and attractive in appearance, wherein said scale indicating section 6 is the sleeve that is installed on the valve body 1 and is positioned at ∩ shape shell-like handwheel inboard, and described graduated scale is shown in the outside of this sleeve, and the drive screw 2 of spool passes this sleeve.
In order can more accurately to regulate flow, spool drive screw 2 Vertical direction have also indicated scale in the excircle upper edge of handwheel 5 lower edges.
Like this, the scale that sleeve upper edge valve core rod direction is indicated is called master calibration, and the scale that indicates on handwheel 5 excircles is called scale graduation, and master calibration and scale graduation are used in combination, and just can fluid flow regulates accurately and shows.
For ease of the layout of handwheel, described spool drive screw and valve body inlet are perpendicular.Like this, handwheel is arranged in the side in addition of valve body entrance and exit easily, has both made whole valve body outward appearance layout attractive in appearance rationally, can make things convenient for operated by handwheel again.
For the gap length between effective regulating spool and the valve outlet, in valve cavity near the position at cavity middle part have one with the perpendicular diaphragm 7 of spool drive screw, diaphragm 7 centers have an open-work 8 to form a valve seat, the drive screw 2 of spool passes this open-work 8, and spool 3 is suitable with this open-work 8.Simultaneously, for the fluid of the valve body that guarantees to flow through can fully pass through valve outlet, this diaphragm engages along the extension of handwheel direction and with valve interior wall at the edge of valve body inlet side, and this diaphragm deviates from the extension of handwheel direction on the edge, edge of valve outlet side and engages with valve interior wall.Like this, fluid has guaranteed that along the curved path valve inner of flowing through fluid can fully pass through valve outlet, thereby, make that also the adjusting of flow is more accurate, reduce deviation.
In addition, be applied to High Temperature High Pressure, and fluid is the occasion of oils, adopts hard sealing, such as the seal ring that adopts metal o-ring or adopt material such as PVC to make at the connection part of valve body for guaranteeing this flow control valve.Avoided adopting soft sealing like this, such as the problem that adopts seal ring that seal with elastometic washer brought to be easy to wear out.
Corroded reduction of service life when preventing that this model utility flow control valve from using in corrosion-prone environment, be coated with electrodeposited coating in the valve body outside.
The valve body of the utility model flow control valve adopts forging and pressing one-body molded, and is processed by high-precision numerical control machine, has advantages of high practicability and long working life.
Above-described flow control valve structure is not only applicable to three-way valve.Be useful in too on other valve body such as two logical, four-way.
The utility model flow control valve is applicable to all kinds of passage pipe fittings such as water, oil, heating installation, has stronger sealability.
