Abstract
The utility model discloses a check valve, which comprises a tubular valve body, wherein a ring-shaped valve seat and a supporting seat are respectively arranged in the tubular valve body, a plate valve core and a return spring are sequentially arranged between the valve seat and the supporting seat, the outer circumference of the axial cross section of the valve core is two arc sections which are connected with each other through a linear section, and the outer circumference of the valve core is matched and connected with the inner wall of the supporting seat. The outer circumference of the axial cross section of the valve core is provided with two arc sections which are connected with each other through the linear section, and the two arc sections are softly connected with the inner wall of the supporting seat, so that technical problems such as seizure in the long-term reciprocating movement of the valve core can be prevented.
Description
Technical field
The utility model relates to a kind of pipeline control device, specifically a kind of one-way valve.
Background technique
The device that is used at present pipe control is mostly valve parts, is mainly stop valve, one-way valve etc.One-way valve generally comprise valve body, motion sealed valve body spool, spool is withstood supporting portion or the elastic member of sealed valve body.Existing one-way valve structures is more complicated mostly, and simple in structure realizes but have defective on fastness with spoke structure or iron wire as supporting portion or elastic member, easily damaged or installation difficulty.Main problem is that the valve core structure in one-way valve is parts that have type frequently reciprocating, and in prior art, spool is along with long use tends to occur the technological deficiencies such as stuck, that flow is less.
Chinese utility model patent numbers 200720147492.2 discloses a kind of one-way valve, comprise that the spool of valve pipe, valve seat, the described valve pipe of movable sealing stream and the end face by the described spool of butt limit the block piece that it moves axially the position, described block piece is a baffle ring, it comprises body and convex tendon, described convex tendon is located at the end towards described spool of described baffle ring, is used for the described end face of the described spool of butt.Its block piece self-position of the one-way valve of this kind structure fixedly have a certain difficulty, do not propose spool yet and prevent stuck solution.
Summary of the invention
It is a kind of simple in structure that the utility model provides, and prevents the one-way valve of stuck, long service life, large flow.
A kind of one-way valve, comprise tubular valve body, be respectively equipped with valve seat and the bearing of ring in tubular valve body, be provided with successively sheet spool, Returnning spring between valve seat and bearing, described poppet shaft is two arc sections that connect by straightway to cross-sectional circumference, the spool periphery bearing inwall that is connected.This kind prevents that by two soft connection bearing inwalls of arc section the technical problems such as stuck from appearring in spool by to cross-sectional circumference, two arc sections that straightway connects being set in poppet shaft in long-term to-and-fro motion.
The inwall that coordinates with the spool periphery as the preferred bearing of structure by four independently suspension column consist of.Four independently the suspension column inner side surface be the arc surface structure, described four arc surfaces all are on a concentric circumference, more effectively coordinate two arc sections of spool to make the to-and-fro motion of spool more smooth and easy, thoroughly prevent stuck.
Described seating circumference is provided with two above flowing holes, to increase the flow of one-way valve integral body.
Described poppet shaft is 10 °-25 ° to straightway and the angle between arc section of cross-sectional circumference, and on probation through long-term experiment, the most smooth and easy with coordinating of bearing at above-mentioned angle lower valve core, stuck probability is little.Described poppet shaft is 0.5-6mm to the length of straigh line of cross-sectional circumference, reduces the spool wearing and tearing on stable basis to guarantee that spool is installed.
The relative sheet spool of the described valve seat outside is provided with filter screen, prevents that impurity from entering valve inner and causing obstruction.
Described valve seat periphery is strengthened the installation strength of valve seat by tin silver welding tubular valve interior wall.
The utility model prevents that by two soft connection bearing inwalls of arc section the technical problems such as stuck from appearring in spool by to cross-sectional circumference, two arc sections that straightway connects being set in poppet shaft in long-term to-and-fro motion.
Description of drawings
Be illustrated in figure 1 as the utility model one-way valve sectional structure schematic diagram;
Be illustrated in figure 2 as the spool perspective view of the utility model one-way valve;
Be illustrated in figure 3 as the bearing perspective view of the utility model one-way valve.
Embodiment
A kind of one-way valve as shown in Figure 1, 2, 3, comprise tubular valve body 1, be respectively equipped with valve seat 2 and the bearing 5 of ring in tubular valve body 1, be provided with successively sheet spool 3, Returnning spring 4 between valve seat 2 and bearing 5, spool 3 axial cross section peripheries are two arc sections 8 that connect by straightway, spool 3 peripheries bearing 5 inwalls that are connected.The inwall that bearing 5 coordinates with spool 3 peripheries by four independently suspension column 10 consist of.What the quantity of suspension column 10 was certain can be set to more than 3 or 4.Bearing 5 circumference are provided with two above flowing holes 9.
As structure preferred four independently suspension column 10 inner side surfaces be arc surface 7 structures, four arc surfaces 7 all are on a concentric circumference.
In order more to be convenient to coordinating of spool 3 and bearing 5, it is 10 °-25 ° at straightway and the angle between arc section 8 of spool 3 axial cross section peripheries.The length of straigh line of spool 3 axial cross section peripheries is 0.5-6mm.
Valve seat 2 relative sheet spool 3 outsides are provided with filter screen 6.Valve seat 2 peripheries are also by tin silver welding tubular valve body 1 inwall.
