Abstract
A valve with conic core features that its core part uses the match of conic body with internal conic surface to control the liquid in pipeline. Said conic body has a control rod on its top and a central through hole in its body. When its through hole is coincident with the through hole of pipeline, the valve is opened. When they are perpendicular to each other, the valve is closed. Said match of conic body with internal conic surface also plays the seal role. Its advantages are high quality and long service life of valve.
Description
The present invention relates to the valve of trickle in the valve of liquid in a kind of controlling plumbing fixtures or the controlling plumbing fixtures, the sealing part that especially can improve the number of times of liquid communication and disconnection in the keyholed back plate road and control position not leakiness is oozed.
At present, the structure of known gate valve, stop valve, ball valve.Gate valve is made up of flashboard, housing and flashboard slot, flashboard lifting screw, screw rod sealing mat and sealing gasket locking screw nurse, handwheel etc.When people have grown switching time, seal mat and be easy to wearing and tearing and spill controlled liquid.Flashboard has combined between the higher and lower levels often, has the mill oblique presentation to give birth to, thereby is not closed completely, and makes quality be not easy to guarantee very much.The structure of stop valve is made up of housing, lid hole seat, valve gap, valve gap screw rod, valve gap screw rod sealing gasket, sealing gasket locking screw nurse, handwheel etc., the people switch often, the valve gap screw rod has a spot wobble, valve gap just is difficult for aiming at the valve cover hole seat, will press to lead partially to make and be not closed completely, and also wearing and tearing easily of sealing gasket, quality is difficult for guaranteeing.The structure of ball lock is an inner ball surface with holes in housing and the housing, and axle on spheroid with holes and the spheroid with holes is a handle on the axle.When work often, understand after spheroid and the inner ball surface wearing and tearing gapped, thereby be not closed completely or out of hand, can not ensure the quality of products.
The purpose of this invention is to provide the valve that a kind of core is cone and cone match structure, it can not only increase many times operating life, and the sealing position is difficult for seepage, and improves the quality of valve.
The object of the present invention is achieved like this: inner conical surface is at valve housing middle part, and housing two ends pipeline through hole and inner conical surface center line directly are greater than the internal diameter of pipeline through hole in the inner conical surface.The height of inner conical surface is greater than the internal diameter of pipeline through hole, cone top is splined shaft, the middle part is the cone through hole, overlapping the outside thread body on the splined shaft, outside thread body center is an internal spline, splined shaft top is the cylindrical jump ring of fixedly outside thread body, and the splined shaft center is a square hole, and the square bar in the square hole is the operating stem of control valve.The height of cone is equal to or greater than the height of inner conical surface, and the middle footpath of inner conical surface is greater than or equals 1.55 times pipeline through hole internal diameter.Operating stem is used for controlling cone rotation, and cone is by the screw thread and the internal thread effect of valve housing of outside thread body, and rotatablely moves up and down, cone and inner conical surface is rotated combine, and cone equates with the inner conical surface tapering, and tapering greater than 15 ° of angles less than 90 ° of angles.When cone was rotated, liquid passed through when the cone through hole at cone middle part and pipeline through hole UNICOM, and cone middle part through hole internal diameter is less than or equal to pipeline through hole internal diameter.When cone through hole and pipeline through hole angle were 90 ° of angles, liquid was disconnected, and the switch number of times is many more, and cone and inner conical surface rotation connecting times are many more, and it is many more that cone and inner conical surface grind number of times, thereby operating life is also just long more.The external splines on the internal spline of outside thread body and cone top can be adjusted and close or during Open valve, the cone through hole at cone middle part and the best angle of pipeline through hole, adjust angle especially for the logical journey of the grinding of cone and inner conical surface with after closing, valve operation bar middle part is a bocca, match with the inner conical surface in valve top cover operating stem hole, on top cover top spring base hole is arranged, spring in the spring base hole withstands the lateral pin on operating stem top, sphere on the bocca of operating stem is combined with the sphere in valve top cover bar hole, thereby reach the process of spin finishing, make to seal between operating stem and the top cover tightly, not leakiness, ooze.For normal pressure valve and Low pressure valve, its internal structure can be simply.Can not want splined shaft, the cylindrical jump ring on outside thread body, cone top.Two kinds of schemes are arranged under low pressure and normal pressure, first kind of valve, in housing inner conical surface and two ends pipeline through hole UNICOM, the footpath is greater than or equals the internal diameter of 1.55 times pipeline through hole in the inner conical surface, the height of inner conical surface is greater than the internal diameter of pipeline through hole, the cone middle part is the cone through hole, the big nose circle of cone top is circular shaft, the circular shaft top is the four directions, and the four directions is used for adorning handle, and the circular shaft outer cover spring, by the valve cover pressure spring, make cone can tightly press inner conical surface, inner conical surface equates that with the tapering of cone the height of cone is more than or equal to the height of inner conical surface.When rotatory handling, in the effect lower cone rotation of circular shaft, when the cone through hole at cone middle part communicated with the pipeline through hole, liquid can pass through in the pipeline, and the cone through hole internal diameter at cone middle part is less than or equal to pipeline through hole internal diameter.When the through hole of cone and pipeline through hole intersected 90 ° of angles, liquid was disconnected, when switch repeats, cone is ground with inner conical surface and is cooperated, tight more with sealing more, no matter be when opening, or when closing, the outside is to be difficult for seepage liquid, second kind of scheme, in housing, the big nose circle of inner conical surface is a through hole, this through hole can be an auxiliary hole, also can be the pipeline through hole of triple valve.When this hole is auxiliary hole, with a benefit core or cover plate this hole is sealed, this is general valve, its working procedure is identical with first kind of scheme, when being triple valve, two ends pipeline through hole and inner conical surface center line intersect, be 90 ° of angles of two ends pipeline through hole and inner conical surface axes intersect, two ends pipeline through hole is same axis, the interior circular diameter at inner conical surface middle part is greater than or equals 1.55 times pipeline through hole internal diameter, and managing all, the internal diameter in hole equates with the big nose circle internal diameter of inner conical surface, the inner conical surface height is greater than pipeline through hole internal diameter, the other end pipeline through hole connects with the big nose circle of inner conical surface, and the big nose circle internal diameter of inner conical surface is less than or equal to the other end pipeline through hole, i.e. pipeline through hole center line and inner conical surface central lines.The little nose circle of inner conical surface is valve operation bar hole, cone roundlet end top is that round bar is an operating stem, the round bar top is the four directions of dress handle, there is individual pin-and-hole at the round bar middle part, round bar is with spring, pressure spring acts on the spring base hole of valve housing, and the other end acts on the pin at round bar middle part, and cone is tightly combined with inner conical surface.Inner conical surface equates with the tapering of cone, and bores greater than 15 ° of angles less than 180 ° of angles.There is a horizontal cone through hole at the cone middle part, and laterally the cone through hole also can be half through hole, at the big nose circle axial direction of cone a hole is arranged also, and it communicates with cross through hole, axial bore and pipeline through hole UNICOM.The big nose circle of cone is the feed liquor body opening, and when the rotation cone made horizontal cone through hole communicate with the pipeline through hole, liquid flow through through horizontal cone through hole by the cone axial bore.Can go out by orifice flow from the two ends pipeline.When horizontal cone through hole was half through hole, liquid can only flow out from a pipeline through hole of an end.When horizontal cone when closing, transverse holes and horizontal pipeline through hole are at an angle of 90.When becoming the angle valve door, the horizontal pipeline through hole needs only an of end, and this working procedure is identical with the triple valve working procedure, and difference is to have only the work of a horizontal pipeline through hole.When closing or open, the big nose circle of cone is under spring pressure and fluid pressure effect, cone and inner conical surface closely cooperate, under spring pressure and the fluid pressure effect, cone and inner conical surface closely cooperate, and number of revolutions is many more, and it is many more to grind number of times, sealing controlling rod position, though when opening or closing easy to leak not.
Owing to adopt such scheme, can improve the control number of times of controlling liquid in the using process of valve, it is non-leakage also can to improve the controlling rod place, can use plastics-production for the valve that is used for normal pressure or low pressure.It is simple in structure.
