Abstract
The utility model relates to a full flux plastic stop valve, which comprises a valve body, a valve core, a valve cover and a valve core control handle. A fluid inlet and a fluid outlet in which the shaft lines are coincident are arranged at two sides of the valve body. Simultaneously the fluid inlet channel in the valve body 1 is a downward inclined channel, whereas the fluid outlet channel is an upward inclined channel. Moreover the valve seat opening in the valve body is arranged at the position between the upside of the fluid inlet channel and the downside of the fluid outlet channel. The plastic stop valve not only can ensure the fluid body to always keep full flux inside the valve body, but also can meet the process requirement of core loosing and demolding of the plastic stop valve; the valve body have the advantages that the structure is compact, the size is small, the material is saved, and the cost is low.
Description
Technical field
The utility model belongs to valve field, specifically relates to a kind of plastic stop valve.
Background technique
In the plastic stop valve of existing 1.6MP, the demoulding of loosing core when making product, goes out circulation road and goes out head piece all to have taked straight structural type influent stream passage, the inflow port of its valve body, and axis overlaps.And the valve seat mouth is arranged on into and out of between the circulation road, makes valve seat mouth below to the distance of influent stream passage lower wall reduce roughly 1/2, makes valve seat mouth top to the distance that goes out the circulation road upper wall also reduce roughly 1/2 equally.Thereby make the area of passage at this place too little, had a strong impact on the inflow-rate of water turbine of this valve like this.In existing metal stop valve, just the inflow port of stop valve is the horizontal linear that overlaps with the medial axis that goes out head piece.Because the making of metal stop valve valve body need not the demoulding of loosing core, so its influent stream passage is crooked curve with the medial axis that goes out circulation road.So just the valve seat mouth can be arranged on influent stream passage top and go out position between the circulation road below, thereby have enough fluxoids.The demoulding but the valve body of plastic stop valve must be loosed core when making can not adopt crooked influent stream passage at all and go out circulation road, so the plastic stop valve of fluxoid can not directly be applied mechanically the structural type of metal stop valve.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and a kind of demoulding of can either can conveniently loosing core when making is provided, and has fluxoid and compact structure, volume is little, low-consuming, cost is low plastic stop valve again.
The purpose of this utility model realizes by following technical measures: this fluxoid plastic stop valve includes valve body, spool, valve gap and spool Joystick, its and arranged on left and right sides at valve body has its medial axis and overlaps mutually, and with the perpendicular inflow port in spool medial axis with go out head piece.Meanwhile the influent stream passage in the valve body is downward-sloping passage, its angle that has a down dip axis and spool medial axis is 55 °～65 °, and the circulation road that goes out in valve body is acclivitous passage, and the angle of its updip axis and spool medial axis is 40 °～60 °.Position between valve seat mouth in the valve body is arranged on influent stream passage top and goes out below the circulation road in addition.
The utility model can also be packed with a copper ring in the valve seat mouth place in valve body, and this valve can be used in hot water pipeline.
The beneficial effects of the utility model are to be the straight line that tilts into and out of the medial axis of circulation road, just can allow the valve seat mouth can be in the top of influent stream passage and go out position between the below of circulation road, thereby guarantee that fluid remains fluxoid in valve body.Tilt angle into and out of circulation road needs only in the scope of defined simultaneously, the releasing process of will loosing core again carries out a bit improving, just can easily the core rod of this plastic stop valve be released, can also make valve body structure compactness, the volume of this plastic stop valve little, materials are economized, cost is low.Thereby make the technical solution of the utility model possess practicability.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural drawing.
Fig. 2 is the utility model embodiment 2 a structural drawing.
Embodiment
The utility model is described further below in conjunction with drawings and Examples: this fluxoid plastic stop valve is made up of valve body 1, spool 2, valve gap 3 and spool Joystick 4.Wherein have inflow port 6 and go out in the head piece 8 in the and arranged on left and right sides of valve body 1, and the medial axis of inflow port 6 overlaps mutually with the medial axis that goes out head piece 8, the while, their medial axis was also perpendicular with the medial axis of spool 2.Influent stream passage in valve body 17 is downward-sloping passage in addition, and the angle of the medial axis of its medial axis and spool 2 is 65 °.Go out circulation road 9 and be acclivitous passage, the angle of the medial axis of its medial axis and spool 2 is 50 °.And the valve seat mouth 5 in the valve body 1 is arranged on influent stream passage 7 tops and go out position between circulation road 9 belows.More than be exactly embodiment 1 of the present utility model.
The utility model embodiment 2 structure is substantially the same manner as Example 1, and just valve seat mouth 5 places in valve body 1 are embedded a copper ring 10.This all-pass plastic stop valve can be used in hot water pipeline.
Claims (2)
