Description
Technical field
The utility model relates to a kind of bottom valve, especially a kind of all-plastic bottom valve.
Background technique
Bottom valve is a kind of valve of energy saving, is generally arranged on the bottom of suction pipe under water pump water, and restriction water pump liquid in pipe returns to water source, plays the function of only import but no export.At present, as flange-type, the common bottom valve of faucet type adopt traditional leaf structure, during work, the alternately change of suction when utilizing pump operation or shut down, pressure, reaches and controls blade spool keying object.Its superposed valve gap of structure and the filtered water cover of bottom, and the blade type spool being positioned at that valve gap and filtered water cover close chamber.Current valve gap and and the intake pipe of water pump between usually adopt Flange joint, a kind of plastic bottom valve etc. of a kind of all-plastic bottom valve and ZL200920163179.7 disclosed in the Chinese utility model patent specification ZL200620116992.5 of my design, it its valve gap is flange, then by the gasket seal between corresponding adpting flange and flange, be connected and sealed with fastening pieces such as clamping bolts.There is following defect when practical application in the bottom valve of this structure: one is that gasket seal easily occurs deterioration phenomenon, affects its sealing; Two is need the component such as gasket seal, fastening piece, and cost is relatively high; Three is connect to need instrument, installs inconvenient.Adopt regular screw threads to be connected in addition between valve gap with filtered water cover, its join strength is low, affects the life-span.
Model utility content
The utility model is the shortcoming for above-mentioned existence, linkage structure on the valve gap providing a kind of all-plastic bottom valve, and its structure is simple, is connected firmly conveniently, and reduces manufacture cost, improves its working life.
The technological scheme that the technical problem that the utility model solves adopts is:
Linkage structure on a kind of valve gap of all-plastic bottom valve, the swagelok 2 comprising filtered water cover 4, valve gap 1 and be connected with valve gap 1, it is characterized in that swagelok 2 is provided with zigzag fashion outside thread 1, the crown of its zigzag fashion outside thread 1 upward, outside thread 1 forms tapering from top to bottom, the inwall of valve gap 1 upper end is provided with the zigzag fashion internal thread one 11 suitable with the zigzag fashion outside thread 1 of swagelok 2, its internal thread 1 forms the tapering identical with the outside thread 1 of swagelok 2 from top to bottom, swagelok 2 precession valve gap 1.
This structure adopts resistance to close pushing away to pull out worm structure, cancel original flanged connecting structure, valve gap and swagelok adopt and are threaded on the one hand, its installation is very convenient, valve gap eliminates flange arrangement in addition, and processing technology simplifies, and eliminates gasket seal and fastening piece, decrease product cost, avoid the easy deterioration phenomenon of gasket seal simultaneously.Adopt resistance to close the pushing away of the utility model scheme to pull out worm structure, its join strength is high, and working life improves greatly, through test of many times and the coherent detection of inventor, and good seal performance.
During concrete enforcement, the bottom of valve gap 1 is provided with zigzag fashion outside thread 2 13, outside thread 2 13 forms tapering from top to bottom, the inwall of filtered water cover 4 upper end is provided with the zigzag fashion internal thread two 41 suitable with valve gap 1 bottom zigzag fashion outside thread 2 13, its internal thread 1 forms the tapering identical with valve gap 1 bottom zigzag fashion outside thread 2 13 from top to bottom, valve gap 1 precession filtered water cover 4.
During concrete enforcement, the outer wall of the outer wall on valve gap 1 and swagelok 2 is provided with straight muscle 3.Straight muscle person easy to use is swagelok precession valve gap.
The beneficial effects of the utility model are: because model utility adopts resistance to close pushing away to pull out worm structure, its structure is simple, and easy for installation, simplify processing technology, decrease product cost, its join strength is high, improves working life large, has certain promotional value.
Embodiment
Fig. 1 and Fig. 2, all-plastic bottom valve comprises valve gap 1, filtered water cover 4 and the swagelok 2 be connected with valve gap 1, swagelok 2 is provided with zigzag fashion outside thread 1, the crown of its zigzag fashion outside thread 1 upward, outside thread 1 forms tapering from top to bottom, outside thread 1 top of swagelok 2 forms sealed step 22, the inwall of valve gap 1 upper end is provided with the zigzag fashion internal thread one 11 suitable with the zigzag fashion outside thread 1 of swagelok 2, its internal thread 1 forms the tapering identical with the outside thread 1 of swagelok 2 from top to bottom, the thread form angle of outside thread 1 and internal thread 1 is 60 degree, pushing away and pulling out tapering is 1: 16, namely 3.5798 degree, tapering limit deviation is-0.005 ~+0.005mm/mm, need not any filler when screwing, screw thread self is relied on to form sealing completely, without any sealing medium between screw thread.Swagelok 2 precession valve gap 1, the sealed step 22 of swagelok 2 withstands on the seal face 12 of valve gap 1, and the outer wall of the outer wall on valve gap 1 and swagelok 2 is provided with straight muscle 3; The bottom of valve gap 1 is provided with zigzag fashion outside thread 2 13, outside thread 2 13 forms tapering from top to bottom, the inwall of filtered water cover 4 upper end is provided with the zigzag fashion internal thread two 41 suitable with valve gap 1 bottom zigzag fashion outside thread 2 13, its internal thread 1 forms the tapering identical with valve gap 1 bottom zigzag fashion outside thread 2 13 from top to bottom, valve gap 1 precession filtered water cover 4.This structure adopts resistance to close pushing away to pull out worm structure, cancels former flanged connecting structure, and valve gap 1 and swagelok 2 adopt and be threaded, and its installation is very convenient; Valve gap 1 cancels flange arrangement, and processing technology simplifies, and saves gasket seal and fastening piece, decreases product cost, avoid the easy deterioration phenomenon of gasket seal simultaneously.Adopt resistance to close the pushing away of the utility model scheme to pull out worm structure, its join strength is high, and the life-span improves greatly, through test of many times and the coherent detection of inventor, and good seal performance.The same prior aries of structure such as the mangetic core assembly under valve gap 1, filtered water cover, space bar, are not described at this.
