Description
Technical field
The present invention relates to a kind of valve, a kind of lever float ball type steam drain valve with filtering function.
Background technology
Lever float ball type steam drain valve is usually used in steam pipe system and equipment, can be automatically drained out condensing water, air and other incoagulable gas, and prevent steam from leaking.
The flange form lever and floating Automatic steam trap Trap of prior art has following defects that owing to valve flowing channel chamber is cast structure, bend is many, and flow resistance is big, and easily blocks, this affects the flow of system to a certain extent, meanwhile, in bend, the impurity of cumulative utilizes for twice equipment to bring potential safety hazard can to downstream hot water, additionally complicated flow passage chamber, return casting and bring inconvenience, not only physicochemical property and the surface quality of foundry goods decreases, and embedded flow passage chamber, the difficulty that its sand removal is suitable.Further, existing valve does not have filtering function, further results in blocking in valve body, and spool is fragile.
Summary of the invention
It is an object of the invention to provide a kind of drain valve, overcome drain valve runner hole complexity in prior art, casting difficulty big and the defect of impeded drainage.
Technical solution of the present invention is as follows:
A kind of drain valve, including valve body and valve gap, valve body is provided with import and export and middle flange face, valve body is arranged over valve gap, being provided with floating ball component and exhaust apparatus, floating ball component and exhaust apparatus in valve gap to be individually fixed on the middle flange face of valve body, exhaust apparatus is positioned at the top of floating ball component, it is provided with spool in valve body, is connected by lever between spool with floating ball component；
The middle flange face of valve body is plum-shaped structure, and import and export is located along the same line, and is provided with dividing plate between import and export；
Described valve body import connects the connector having screen pipe and internal diameter more than screen pipe external diameter, described screen pipe is positioned in the inner chamber of connector, described screen pipe has the body of outer end closure, there is on described tube wall the external spiral groove being rounding post with body, there is on described inboard wall of tube body the inner spiral groove being rounding post with body, described external spiral groove and inner spiral groove are oppositely oriented, and the groove depth of described external spiral groove and the groove depth sum of inner spiral groove are more than the wall thickness of body to form the filter opening of rhombus on body.
Further: described external spiral groove is single thread groove, described inner spiral groove is multi-head spiral groove.
Further: described external spiral groove and inner spiral groove are Variable lead groove, body needs the helical pitch helical pitch more than the position that need not bending of crooked position.
Further: the revolver profile of described external spiral groove normal section profile and right wheel profile all tilt to homonymy.
Further: described external spiral groove normal section profile gradually broadens along the width of rebate of body radially direction external spiral groove the most from inside to outside.
Further: described dividing plate is connected with middle flange face, import straight-through valve cover cavity, in the angle of 50 degree between outlet and dividing plate, one end of outlet is connected along dividing plate with import, and the other end of outlet is the trapezoidal cavity that opening amplifies；
The middle uniform screwed hole of flange face periphery, middle part is provided with discharge outlet and exhaust outlet, and exhaust outlet is positioned at above discharge outlet, and screwed hole is connected with trapezoidal cavity.
The present invention compared with prior art has the advantage that
The present invention is by transforming the outlet flow of valve inner, make the most embedded complicated casting runner, become simple machined structures, solve impurity to block, the problem that flow resistance is bigger, make foundry goods ordinary sand casting become accurate Ludox casting simultaneously, physicochemical property and the surface accuracy of valve body are greatly enhanced, improvement due to structure, also make about the middle flange height reduction half of valve body, alleviate valve weight, save cost, additionally also by the Curve guide impeller to valve gap, add label boss and a spike and improve identification information, the I&M making valve becomes simple and convenient.
And, described valve body import connects the connector having screen pipe and internal diameter more than screen pipe external diameter, current can be filtered, prevent blocking in valve body further, spool is avoided to damage, and described screen pipe has the following advantages relative to common screen pipe: (1) screen pipe has external spiral groove, current outside pipe are under pressure along external spiral groove helical flow, impurity is distributed outside tube wall more uniform, utilization and the loss of filter opening are more uniform, and add water and flow through the number of times of filter bores, improve filter efficiency；(2) current inside and outside screen pipe flow along inner spiral groove and external spiral groove respectively, collide each other at filter opening such that it is able to the impurity impact being blocked in outside filter opening fallen, reach the purpose of screen pipe self-cleaning, reduce cleaning cost；(3) current in screen pipe form the uniform current of flow velocity along inner spiral groove helical flow, water one through filtering enters screen pipe and is flowed along inner spiral groove by the guiding of current in inner spiral groove immediately, reach the effect of steady in-pipe flow, and external spiral groove be single thread groove, inner spiral groove be that the structure of multi-head spiral groove contributes to being scattered in different inner spiral grooves through the moisture filtered, reduce further the water having just enter in body to the impact of water in pipe；(4) screen pipe has inner spiral groove and external spiral groove, contribute to the bending of body, and electric-heating-wire-heating can be entered at external spiral groove inner disc when bending, reduce further the camber of bending, on the other hand, body needs the helical pitch helical pitch more than the position that need not bending of crooked position, reduces the possibility that bending causes body to rupture；(5) external spiral groove and inner spiral groove are Variable lead groove, can realize controlling the function of water velocity inside and outside screen pipe diverse location by the helical pitch setting different parts；(6) the revolver profile of external spiral groove normal section profile and right wheel profile all tilt to homonymy, ensure when turning inner spiral groove to avoid collapsing cutter by selecting turning direction to make cutter vehicle all be acutangulated by the direction on inside base, outside to lathe tool direct of travel when inner spiral groove and external spiral groove intersection and external spiral groove two side, reduce difficulty of processing；(7) width of rebate of screen pipe external spiral groove gradually broadens along body radially direction the most from inside to outside, contribute to being filled in external spiral groove by fluid sealant by fashion of extrusion in process, fluid sealant bottom external spiral groove is filled finer and close, further avoid and occur collapsing cutter at inner spiral groove and external spiral groove intersection when turning inner spiral groove.
