Abstract
The utility model provides a kind of flap valve of anticreep hinge, comprises hinge, door leaf, gate seat, sealing V band etc.Door leaf is connected with gate seat by hinge.Described hinge comprises, bolt, hinged floor, hinge A plate, hinge B plate, and hinged floor and hinge A plate are welded and fixed, and form entirety with door leaf assembly welding, hinge B plate and gate seat assembly welding in aggregates, hinged to realize relative movement by bolt.The utility model is to improve hinge structure, adopt novel bolt, increasing screw thread and boring at tail end, by installing slotted nut and cotter pin fixed hinge A plate and hinge B plate additional, preventing in long-term work because bolt loosens and wearing and tearing and make hinge A plate and hinge B plate produce play down to coming off.
Description
Technical field
The utility model relates to the total controlling component of fluid delivery system, i.e. valve and gate valve, particularly a kind of flap valve of anticreep hinge.
Background technique
Flap valve is widely used in the circle of unimodal current and square water outlet, has and prevents outer water from pouring in down a chimney function, vertebration, reliable operation, and without the need to manual operation, hoisting capacity, from source pressure, is then opened when the hydraulic pressure in flap valve is greater than flap valve outside pressure; Otherwise then close.Belong to a kind of energy-conservation, convenient and check valve that the life-span is long.
The flap valve of conventional hinge more is in the market used for hinged bolt and adopts Cock screw location, because water pump vane peripheral velocity remains unchanged, when flow reduces (increase), lift raises (reduction), know that blade outlet angle diminishes (becoming large) by Euler's equation, at this moment blade exit and the vane inlet liquid stream angle of attack become large, the separation of flow can be produced, impact, cavitation, namely current produce certain thrust to flap valve, and abrasion and corrosion causes the loosening and play of fastening piece on flap valve hinge, the bolt caused in flap valve hinge comes off by long-time running, cause device damage.How to address this problem is real problem anxious to be resolved at present.
For this reason by lengthening bolt, fixing, bolt can be avoided to come off with slotted nut and cotter pin, the equipment long-term stability of guarantee is run.
Summary of the invention
For the deficiencies in the prior art part, the utility model provides a kind of flap valve of anticreep hinge, and bolt loosens and comes off can to prevent flap valve from occurring at work.
For achieving the above object, the technical solution adopted in the utility model is:
The flap valve of a kind of anticreep hinge of the present utility model, comprises hinge, door leaf, gate seat, and described hinge comprises bolt, hinged floor, hinge A plate, hinge B plate; Hinged floor is fixedly connected with hinge A plate, and is connected to form entirety with door leaf, and hinge B plate is fixedly connected with in aggregates with gate seat; Described hinge A plate and described hinge B plate are rotationally connected by bolt; It is characterized in that, the tail end stretching out hinge A plate at described bolt arranges fixing device and is fixed.
Preferably, described fixing device is slotted nut, has screw thread in described slotted nut, and described bolt is provided with the screw thread matched with slotted nut.
Preferably, in described bolt tail end boring, slotted nut is fixed by cotter pin.
Preferably, Cock screw is comprised; Be provided with screw hole at described hinge A plate side opening, described Cock screw fixes described bolt through described screw hole.
Preferably, sheathed nut in the part exposing hinge A plate at described Cock screw.
Compared with prior art, the beneficial effect that the utility model has is:
1) the utility model improves operational efficiency and the reliability of equipment, the delay apparatus life-span;
2) run under the environment that the utility model can be used in compared with mass-flow thrust.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the flap valve structural representation of a kind of anticreep hinge structure of the utility model.As shown in Figure 1, the flap valve of a kind of anticreep hinge structure of the present utility model comprises hinge 1, sealing V band 2, door leaf 3 and gate seat 4.
Fig. 2 is the flap valve hinge structure schematic diagram of a kind of anticreep hinge of the utility model.As shown in Figure 2, the hinge 1 of the flap valve of a kind of anticreep hinge of the present utility model comprises Cock screw 1.1, nut 1.2, bolt 1.3, slotted nut 1.4, cotter pin 1.5, hinged floor 1.6, hinge A plate 1.7, hinge B plate 1.8.Hinged floor 1.6 and hinge A plate 1.7 are welded and fixed, and form entirety with door leaf 3 assembly welding, and hinge B plate 1.8 is in aggregates with gate seat 4 assembly welding, hinged to realize relative movement by bolt 1.3.
Screw hole is provided with at hinge A plate side opening, the screw thread matched with the screw thread on Cock screw 1.1 is had in screw hole, Cock screw 1.1 fixes bolt through screw hole, and in the part exposing hinge A plate at Cock screw 1.1, sheathed nut 1.2 is for further fixing.The position corresponding to screw hole in bolt side can arrange screw slots simultaneously, and the afterbody of Cock screw 1.1 is against on screw slots, realizes further fixing.The utility model adopts novel bolt 1.3, for lengthening bolt, the tail end stretching out hinge A plate at bolt is provided with screw thread and boring, by installing the internal thread slotted nut corresponding with the screw thread on bolt 1.4 fixed hinge A plate 1.7 and hinge B plate 1.8 additional, further fixed through boring by cotter pin 1.5 simultaneously, prevent in long-term work because bolt loosens and wear and tear and make chain A plate 1.7 and hinge B plate 1.8 produce play so that come off.
Described in the utility model, concrete case study on implementation is only better case study on implementation of the present utility model, is not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of the utility model claim change and modify, all should as technology category of the present utility model.
