Abstract
The utility model relates to a constant-flow regulation valve, which is mainly composed of a valve body, a flow guide valve core, and a sliding valve core, wherein, a flow guide valve cavity of the flow guide valve core and a sliding valve cavity of the sliding valve core are arranged in the valve body; the flow guide valve cavity, the sliding valve cavity, an inlet and an outlet are communicated with each other; the upper side of the sliding valve core is provided with a spring; the center lines of the flow guide valve cavity and the sliding valve cavity are parallel with each other; the central lines of the inlet and the outlet are respectively perpendicular to the central line of the flow guide valve cavity or the central line of the sliding valve cavity. The utility model has the advantages of simple structure, compact external shape, small volume, and small installation size. The inlet and the outlet can be arranged in a straight-way type in the direction of 180 DEG, and the installation procedure of a pipeline is simplified.
Description
The utility model relates to a kind of valve, a kind of especially constant flow regulation valve.
Existing constant flow modulating valve is made up of flow-guiding valve and guiding valve, be provided with vertical with sliding spool of water conservancy diversion spool in its valve body.The shortcoming of this structure maximum is that volume is big, and complex process, cost height, and import and export can only become the angie type settings of 90 degree directions.Pipeline generally all is a lineal shape, has so just brought great difficulty to installation, and pipeline will be rolled over secondary 90 degree bent angles just can connect rectilinear duct, has not only increased the complexity of pipeline, has also increased the pressure loss of line fluid simultaneously.
The purpose of this utility model provides a kind of simple in structure, compact appearance, constant flow regulation valve that volume is little.
Technical solution of the present utility model is, mainly form by valve body, water conservancy diversion spool and sliding spool, valve body is provided with import and outlet, be provided with water conservancy diversion valve pocket and piston chamber that water conservancy diversion spool and sliding spool are set in the valve body, water conservancy diversion valve pocket and piston chamber and import and outlet are led to mutually, the upside of sliding spool is provided with spring, and the center line of water conservancy diversion valve pocket and piston chamber is parallel to each other, and the center line of import and outlet is respectively perpendicular to the center line of water conservancy diversion valve pocket or piston chamber.
The utility model has the advantages that, simple in structure, compact appearance, volume and installation dimension are little, and import and export can realize the straight-through type setting of 180 degree directions, have simplified the installation procedure of pipeline greatly.Reduce the pressure loss, flow control is stable.
Fig. 1 is a structural representation of the present utility model.
The utility model mainly is made up of valve body 1, water conservancy diversion spool 3 and sliding spool 10.Valve body 1 is provided with import A and outlet B, is provided with water conservancy diversion valve pocket C and piston chamber D in the valve body 1, interlinks by passage E and passage F respectively between water conservancy diversion valve pocket C and the piston chamber D.Import A communicates with passage F and communicates with water conservancy diversion valve pocket C, and outlet B communicates with piston chamber D.The center line of water conservancy diversion valve pocket C and piston chamber D is parallel to each other, and the center line of import A and outlet B is respectively perpendicular to the center line of water conservancy diversion valve pocket C or piston chamber D.
Water conservancy diversion spool 3 and sliding spool 10 are arranged at respectively in water conservancy diversion valve pocket C and the piston chamber D, and also, the shaft axis of water conservancy diversion spool 3 and sliding spool 10 is parallel to each other.The upside of the sliding spool 10 in the piston chamber D is provided with adjustable lever 7, is provided with spring 8 between adjustable lever 7 and the sliding spool 10, with Regulation spring pressure.By scyewed joint water conservancy diversion valve gap 5 and slide valve cover 6 are housed on the valve body 1, the inboard of valve gap 5, valve gap 6 links with water conservancy diversion spool 3 and adjustable lever 7 respectively by screw thread again, and valve gap 5, valve gap 6 seal water conservancy diversion valve pocket C and piston chamber D respectively.Be provided with between water conservancy diversion spool 3 and the valve body 1 in the water conservancy diversion valve pocket C and transfer stream screen casing 2, transfer stream screen casing 2 to be provided with a through hole that communicates with valve body 1 upper channel E.Be provided with constant current screen casing 9 and slide valve buckle 11 between piston chamber D internal spool valve core 10 and the valve body 1.Constant current screen casing 9 is provided with a through hole that communicates with valve body 1 upper channel E, thereby water conservancy diversion valve pocket C and piston chamber D are communicated.Slide valve buckle 11 be provided with one with the outlet B corresponding throttle orifice G that communicates.
During work, import medium one tunnel directly flows to the lower end of piston chamber D through passage F, directly acts on the lower end of sliding spool 10, and another road flows to the upper end of sliding spool 10 by water conservancy diversion valve pocket C, and with the upper end of spring pressure acting in conjunction in sliding spool 10.Do not wait owing to act on the pressure at sliding spool 10 two ends, sliding spool 10 promptly moves axially, and the Lift of the throttle orifice G in the piston chamber D outside also changes along with moving of sliding spool 10.When the pressure at sliding spool 10 two ends reached balance, sliding spool 10 promptly was in certain position.When inlet pressure increased, sliding spool 10 moved up, and throttle orifice G diminishes, and rate of discharge diminishes.In order to make rate of discharge keep constant, the enable possition by handwheel 5 adjusting water conservancy diversion spools 3 makes sliding spool 10 return to initial rest position, to guarantee that rate of discharge is constant.Vice versa.
