Abstract
The utility model relates to a high pressure liquid check valve, comprising a left flange, a right flange, a fastener, an O-shaped seal ring, a perforated screw, a locating guiding sleeve, a seal plate, an elastic component, and a check valve plug, wherein the left flange and the right flange are connected together through the fastener; the O-shaped seal ring is disposed between the left flange and the right flange; the locating guiding sleeve is fixed on the left flange after passing through the perforated screw; the seal plate is disposed between the left flange and the locating guiding sleeve; the check valve plug has one end connected to the right flange through the elastic component and the other end disposed on the seal plate; and the check valve plug can move from left to right along an axial direction of the locating guiding sleeve. The high pressure liquid check valve is easy to make and reliable to use, has low cost, high pressure withstand limit, and a long service lifetime, and requires no operation and maintenance.
Description
Technical field
The utility model relates to a kind of one-way valve, and particularly a kind of highly pressurised liquid one-way valve belongs to the valving technical field.
Background technique
One-way valve is check valve, safety check again.Its effect is only to allow fluid to flow to a direction, if during adverse current, valve is promptly 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 than in the small flow high pressure system, after meeting the demands, needs throttle down voluntarily, uses very inconvenience, and it is short that too much open and close have influenced the working life of one-way valve.
The model utility content
The utility model purpose is for the deficiency that overcomes existing technology 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 to be provided.
For achieving the above object, the technological scheme that the utility model adopts is: 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; Said left flange and right flange link together through fastening piece; Be provided with the O RunddichtringO between said left flange and right flange; Said positioning and guiding cover is through boring a hole screw on left flange; Said sealing plate is arranged between left flange and the positioning and guiding cover; One end of said nonreturn valve core is arranged on the right flange through elastic member, and the other end is arranged on the sealing plate; Said nonreturn valve core can axially horizontally slipping along the positioning and guiding cover.
Preferably, said fastening piece is a bolt.
Preferably, said elastic member is a spring.
Preferably, said sealing plate is a rubber gasket sheet.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The highly pressurised liquid one-way valve of the utility model is made simple and easyly, with low cost, uses reliably, and the withstand voltage limit is high, need not operation and maintenance.When the highly pressurised liquid one-way valve of the utility model 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 the utility model technological scheme is described further:
Accompanying drawing 1 is the structural representation of the highly pressurised liquid one-way valve of the utility model;
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 and specific embodiment the utility model is done further to specify.
The described a kind of highly pressurised liquid one-way valve of the utility model shown in accompanying drawing 1 comprises 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; Said left flange 1 links together through fastening piece 3 with right flange 2; 2 of said left flange 1 and right flanges are provided with O RunddichtringO 4; Said positioning and guiding cover 6 is fixed on the left flange 1 through perforation screw 5; Said sealing plate 7 is arranged between left flange 1 and the positioning and guiding cover 6; One end of said nonreturn valve core 9 is arranged on the right flange 2 through elastic member 8, and the other end is arranged on the sealing plate 7; Said nonreturn valve core 9 can overlap 6 axially horizontally slip along positioning and guiding; Said fastening piece is a bolt; Said elastic member is a spring; Said sealing plate is a rubber gasket sheet.
During use, left end is the highly pressurised liquid inlet, and highly pressurised liquid promotes nonreturn valve core 9 and moves right through perforation screw 5, and nonreturn valve core 9 and sealing plate 7 are broken away from.Thereby highly pressurised liquid is able to pass, 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 by purpose.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The highly pressurised liquid one-way valve of the utility model is made simple and easyly, with low cost, uses reliably, and the withstand voltage limit is high, need not operation and maintenance.When the highly pressurised liquid one-way valve of the utility model 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.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
