Abstract
The utility model discloses a flow control valve of a water supply connector. The flow control valve comprises a valve body, a press plate, a valve core, a valve rod and an O-shaped seal ring, wherein the press plate is provided with a limiting groove which is composed of a round hole and two lugs disposed on the round hole, two sides of the same lug are perpendicular to each other ,opposite sides of the two lugs are parallel with each other, two planes which are parallel with each other are disposed on the valve rod, and the distance d between the two planes corresponds with the distance D between the two parallel sides of the two lugs. The flow control valve provided by the utility model has the characteristics of being reasonable in structure, easy to process, convenient to assemble, capable of realizing flow accurate control, and the like.
Description
Technical field
The utility model relates to a kind of control valve, especially relevant with flow control valve.
Background technique
The validity of flow control is the most important performance index of water supply connector flow control valve, traditional water heater water inlet connector flow control valve normally adopts pin on the valve rod location in restraining groove to play to control flow effect, due to draw-bore on valve rod, during boring, position is difficult to fix, and the degree of depth in hole is more shallow, add machining error and the assembly error of pin itself, when these factors cause water supply connector to carry out switch, can not realize the accurate switch of an angle of 90 degrees, as can not standard-sized sheet, cause underfed, as can not complete shut-down, cause flow to surpass regulation requirement.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, process simple, easy to assembly, to realize precise control of flew water supply connector flow control valve.
For achieving the above object, the utility model is achieved through the following technical solutions.Water supply connector flow control valve, comprise valve body, pressing plate, spool, valve rod and O RunddichtringO, on valve body, be provided with water inlet and current adjustment hole, spool and valve rod are connected as a single entity, spool matches with current adjustment hole, O RunddichtringO is located between spool and current adjustment hole, pressing plate is provided with restraining groove, restraining groove on pressing plate is by being comprised of circular hole and two projections that arrange on circular hole, the dual side-edge of same projection is perpendicular, the opposite side-edge of two projections be arranged in parallel respectively, on valve rod, offer two planes that parallel, distance B between distance d between the two planes parallel sides relative with two projections is corresponding.
Described water supply connector flow control valve, its two projection is annular lug, the inner ring of two projections is concentric circular arc.
Described water supply connector flow control valve, the external arc of its valve rod matches with circular hole.
Described water supply connector flow control valve, the symmetrical setting of its two projection.
The utility model compared with prior art has the following advantages: (one) is because the restraining groove on pressing plate is circular hole and projection cube structure form, adopt valve rod to parallel the control mode that the plane parallel sides relative with two projections matches and locate, greatly improve the accurate control of flow, can conveniently realize the accurate control of 90 degree; (2) be to have reduced the technique of punching on circular valve rod, saved pin, processing is simple, has reduced product cost; (3) be the efficiency of assembling that greatly improved product, promoted product performance; (4) be the application area of further having expanded water supply connector flow control valve, not only can be used for gas water-heater and electric water heater, and can be for needing accurately to control the occasion of flow in industrial production and daily life.
