Abstract
The invention discloses a high pressure liquid one-way valve which comprises a left flange, a right flange, a fastening piece, an O-shaped seal ring, a perforation screw, a localization guide sleeve, a sealing plate, an elastic part and a one-way valve core, wherein the left flange and the right flange are connected together through the fastening piece; the O-shaped seal ring is arranged between the left flange and the right flange, and the localization guide sleeve is fixed on the left flange through the perforation screw; the sealing plate is arranged between the left flange and the localization guide sleeve, one end of the one-way valve core is arranged on the right flange through an elastic part, and the other end of the one-way valve core is arranged on the sealing plate; and the one-way valve core can slide along the localization guide sleeve axially from left to right. The high pressure liquid one-way valve provided by the invention has the advantages that the manufacture is simple, the cost is low, the use is reliable, the withstand voltage limitation is high, the operation and maintenance are not needed, and the service life is long.
Description
Technical field
The present invention relates to a kind of one-way valve, particularly a kind of highly pressurised liquid one-way valve belongs to the valving technical field.
Background technique
One-way valve is again check valve, safety check.Its effect is only to allow fluid to flow to a direction, and during if there is adverse current, valve is namely closed voluntarily, scurries into low service system to prevent high-pressure liquid.
Existing one-way valve structures is too complicated, and fabricating cost is high, and rate of fault is high, is used in particular for needing voluntarily throttle down than in the small flow high pressure system after meeting the demands, and it is very inconvenient to use, and it is short that too much open and close have affected the working life of one-way valve.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of simple and easy, easy to use and reliable, as to need not operation and maintenance highly pressurised liquid one-way valve of making.
Technical solution of the present invention is achieved in that a kind of highly pressurised liquid one-way valve, comprise left flange, right flange, fastening piece, O RunddichtringO, perforation screw, positioning and guiding cover, sealing plate, elastic member, nonreturn valve core; Described left flange and right flange link together by fastening piece; Be provided with the O RunddichtringO between described left flange and right flange; Described positioning and guiding cover is fixed on the left flange by the perforation screw; Described sealing plate is arranged between left flange and the positioning and guiding cover; One end of described nonreturn valve core is arranged on the right flange by elastic member, and the other end is arranged on the sealing plate; Described nonreturn valve core can axially horizontally slipping along the positioning and guiding cover.
Preferably, described fastening piece is bolt.
Preferably, described elastic member is spring.
Preferably, described sealing plate is rubber gasket sheet.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Highly pressurised liquid one-way valve of the present invention is made simple and easyly, with low cost, uses reliably, and the withstand voltage limit is high, need not operation and maintenance.When highly pressurised liquid one-way valve of the present invention is in cut-off state, because the effect of elastic member is pressed in sealing plate to nonreturn valve core, thereby reach the purpose of protection sealed rubber plate, improved working life.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing l is the structural representation of highly pressurised liquid one-way valve of the present invention;
Wherein: 1, left flange; 2, right flange; 3, fastening piece; 4, O RunddichtringO; 5, perforation screw; 6, positioning and guiding cover; 7, sealing plate; 8, elastic member; 9, nonreturn valve core.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be a kind of highly pressurised liquid one-way valve of the present invention as shown in Figure 1, comprise left flange 1, right flange 2, fastening piece 3, O RunddichtringO 4, perforation screw 5, positioning and guiding cover 6, sealing plate 7, elastic member 8, nonreturn valve core 9; Described left flange 1 and right flange 2 link together by fastening piece 3; 2 of described left flange 1 and right flanges are provided with O RunddichtringO 4; Described positioning and guiding 6 covers are fixed on the left flange 1 by perforation screw 5; Described sealing plate 7 is arranged between left flange 1 and the positioning and guiding cover 6; One end of described nonreturn valve core 8 is arranged on the right flange 2 by elastic member 9, and the other end is arranged on the sealing plate 7; Described nonreturn valve core 9 can overlap 6 axially horizontally slip along positioning and guiding; Described fastening piece is bolt; Described elastic member is spring; Described sealing plate is rubber gasket sheet.
During use, left end is the highly pressurised liquid entrance, and highly pressurised liquid promotes nonreturn valve core 9 and moves right by perforation screw 5, and nonreturn valve core 9 and sealing plate 7 are broken away from.Thereby highly pressurised liquid passed, and flows to the right-hand member outlet.When the left end highly pressurised liquid was closed, nonreturn valve core 9 was moved to the left under right-hand member elastic member 8 and highly pressurised liquid make a concerted effort to promote, and nonreturn valve core 9 contacts with sealing plate 7, fastens, and reaches the cut-off purpose.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Highly pressurised liquid one-way valve of the present invention is made simple and easyly, with low cost, uses reliably, and the withstand voltage limit is high, need not operation and maintenance.When highly pressurised liquid one-way valve of the present invention is in cut-off state, because the effect of elastic member is pressed in sealing plate to nonreturn valve core, thereby reach the purpose of protection sealed rubber plate, improved working life.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
