Description

A kind of turnover plate type non-return valve
Technical field
The utility model is related to a kind of non-return valve more particularly to a kind of turnover plate type non-return valves.
Background technology
Traditional non-return valve, such as double by enabling non-return valve, the general double-joint type non-return valve for using ball-type or hemispheric, it exists There is following deficiency:Ball-type or hemispheric are also easy to produce resonance under water environment, and noise can be caused in entire pipe-line system.Needle To disadvantages mentioned above, it is thus proposed that a kind of technical solution of turnover plate type non-return valve.
A kind of traditional turnover plate type non-return valve, valve seat and a flap including setting fluid channel in one.Flap rotation connects It is connected on valve seat and can swing between open and closed positions, forward stream physical efficiency effect flap makes flap be in corresponding fluid The open position that channel is opened, counter fluid, which can act on flap, makes flap be abutted against annular convex platform end face in sealing to close fluid The closed position of channel.Flap includes coupling part, and connecting portion sets up pivot separately, pivots and be connected to valve seat, pivot and valve seat It adopts and is tightened by bolts together, therefore there are following deficiencies:First, realize locking, packaging efficiency using 8~12 sets of bolts It is relatively low;Second, bolt is metal material, dare not be selected under acid or alkali environment, application scenario is restricted.
Against the above deficiency, Chinese patent database discloses a solution, such as CN106195361A.The valve seat is set Have a connected unit, be convexly equipped with two spaced apart projection seats on the connected unit, the opposite of practising physiognomy of the projection seat be recessed with one pass to it is convex The link slot of seat terminal surface and a transverse groove that is vertical and connecting link slot;The coupling part is folded between two projection seats, the pivot Axis connection enables pivot to be rotated relative to link slot, coupling part is enable to be rotatably connected on valve seat in link slot.Separately in the transverse direction Fixture block is arranged at slot, limiting pivot by fixture block is disconnected slot.Though it can solve above-mentioned deficiency, can bring it is new not Foot part:There are the risks for dropping out or being broken under transport or impact of water hammer for fixture block.
Utility model content
The utility model provides a kind of turnover plate type non-return valve, and which overcome turnover plate type non-return valve institutes a kind of in background technology Existing deficiency.
The used technical solution that the utility model solves its technical problem is:
Including valve seat (10) and flap (20), fluid channel (30) is set in the valve seat (10) for a kind of turnover plate type non-return valve, should Flap (20) is rotatably connected on valve seat (10) and can swing between open and closed positions, and the valve seat (10) is including housing Partly (11) and fixed seat (12), the fixed seat (12) set through hole, which forms the part of fluid channel (30);This is solid The end face of reservation (12) is convexly equipped with the protrusion (13) at two intervals, and the outer wall backwards to through hole of the protrusion (13) is recessed fluted (14);The flap (20) has connecting portion (21), and the two sides of the connecting portion (21) are all convexly equipped with shaft (22), two shaft (22) adaptation is connected in two grooves (14) and forms rotation connection, and the connecting portion (21) is between two protrusions (13);This is solid Reservation (12) can be fixedly attached into housing parts (11), and limit shaft by fixed seat (12) and housing parts (11) inner wall (22) it is detached from groove (14).
Among one embodiment:The housing parts (11) include hollow valve pocket (111), pipe fitting (112) and nut (113), which extends outward into the first ring convex, which extends internally Into the second ring convex, which is socketed pipe fitting (112) and is screwed onto valve pocket (111), the second ring convex first ring convex of contact Valve pocket (111), pipe fitting (112) and nut (113) to be connected;Valve pocket (111) inner wall is at least provided with a support Face (114), fixed seat (12) contact are set between supporting surface (114) and pipe fitting (112) end face, the groove (14) and valve pocket (111) inner wall cooperation limitation shaft (22) is detached from groove (14).
Among one embodiment:Valve pocket (111) inner wall is convexly equipped with rib, this is right for one end opposing valve sleeves (111) of the rib Should port inside contract, one end end face of the rib forms above-mentioned supporting surface (114).
Among one embodiment:The fixed seat (12) includes a periphery wall, an internal perisporium and an affixed periphery wall and internal perisporium Ring wall;Two protrusion (13) is fixed on the periphery wall and internal perisporium;Fixed seat (12) the periphery wall contact is set on supporting surface (114) between pipe fitting (112) end face.
Among one embodiment:The flap (20) is fixed in the wall of top wall portion including a top wall portion and a upper peripheral edge (23), which has the extension stretched out except wall (23), and the outer diameter of the extension is more than internal perisporium internal diameter, The outer diameter of the wall is less than internal perisporium internal diameter, flap in the closed position (20):The wall (23), should within internal perisporium Extension sealing abuts against internal perisporium end face.
Among one embodiment:Wall (23) bottom periphery extends radially outwardly into lower ring wall, which is less than interior Peripheral wall internal diameter, the lower ring wall and extension between the upper and lower every and formed attaching annular groove (24);Another that gasket seal (25) is arranged, this is close Gasket (25) socket wall (23) is simultaneously installed in attaching annular groove (24), which, which has, flushes outside top wall portion Periphery simultaneously stretches out the hermetic unit except lower ring wall, which, which can seal, abuts against internal perisporium end face.
Among one embodiment:The end slope arrangement of the internal perisporium, and the inclination arrangement is the correspondence by fixed seat (12) The angle of the flow direction of the forward direction fluid of the side of protrusion (13) to the direction of radial direction opposite side and fluid channel (30) is acute angle.
Among one embodiment:The pipe fitting (112) one end inner peripheral also extends internally into third ring convex, the fixed seat (12) it is supported by the first ring convex and third ring convex.
Compared with background technology, it has the following advantages that the technical program:
