Abstract
The utility model discloses high stability flap valve, it comprises flap valve body, flap valve core, toggle and locating stud, between described flap valve core and flap valve body, be provided with 9 ° of inclination angles, the end thread of described locating stud is combined with nut, between described locating stud and nut, adaptation has axle jump ring, the upper lower limb of described flap valve core and flap valve body contacting point are provided with seal ring, and described seal ring is crimped with stainless steel platen by bolt.The beneficial effects of the utility model are that flap valve body takes 9 °, are convenient to that hydraulic pressure is very little just easily to be opened; Seal ring replaces adhesive tape and is crimped on flap valve core by stainless steel platen, has strengthened the sealability of flap valve entirety and the stability of seal ring; Wedge-shaped catch and seal ring and stainless steel platen coordinate realizes reliable and stable sealing, and stage clip can alleviate the destruction of flap valve core to flap valve body, increases the service life.
Description
Technical field
The utility model relates to the check valve apparatus of realizing check and cutout for water supply and sewage work, relates in particular to high stability flap valve.
Background technique
Be installed on the tail end of drainage pipe, have and prevent that outer water from pouring in down a chimney the check valve of function.Flap valve is mainly that flap valve body, valve plate are that flap valve core, Mi Tufengquan, hinge four parts form by valve seat.Shape is divided into circular and square.The material of flap valve is various fabricated metalss traditionally, has developed into now multiple composite material.
Existing flap valve adopts adhesive tape to be bumped into, and sealing effect is bad, and adhesive tape is changed trouble after damaging, and flap valve core in the time opening due to slow from reopening, while closing, clash into fiercely with flap valve body, these factors all affect the stability that flap valve moves.
Model utility content
The unstability factors such as the technical problems to be solved in the utility model is that existing flap valve exists sealing unreliable, and it is fragile that maintenance difficult, flap valve body and the operation of flap valve core are of a specified duration provide a kind of high stability flap valve for this reason.
The technical solution of the utility model is: high stability flap valve, it comprises flap valve body, flap valve core, toggle and locating stud, between described flap valve core and flap valve body, be provided with 9 ° of inclination angles, the end thread of described locating stud is combined with nut, between described locating stud and nut, adaptation has axle jump ring, the upper lower limb of described flap valve core and flap valve body contacting point are provided with seal ring, and described seal ring is crimped with stainless steel platen by bolt.
The improvement of such scheme is: on described flap valve body inwall, be connected with the wedge-shaped catch coordinating with stainless steel platen inclined-plane, the end of described wedge-shaped catch and seal ring close contact, the inside of described wedge-shaped catch offers the opening slot of level towards seal ring, and the interior adaptation of described opening slot has the stage clip with seal ring close contact.
The beneficial effects of the utility model are that flap valve body takes 9 °, are convenient to that hydraulic pressure is very little just easily to be opened; Seal ring replaces adhesive tape and is crimped on flap valve core by stainless steel platen, has strengthened the sealability of flap valve entirety and the stability of seal ring; Wedge-shaped catch and seal ring and stainless steel platen coordinate realizes reliable and stable sealing, and stage clip can alleviate the destruction of flap valve core to flap valve body, increases the service life.
Brief description of the drawings

Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B place partial enlarged drawing of Fig. 2;
In figure, 1, flap valve body, 2, flap valve core, 3, locating stud, 4, seal ring, 5, stainless steel platen, 6, pad, 7, axle jump ring, 8, bolt, 9, wedge-shaped catch, 10, stage clip.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Figure 1-3, the utility model comprises flap valve body 1, flap valve core 2, toggle and locating stud 3, between described flap valve core and flap valve body, be provided with 9 ° of inclination angles, the end thread of described locating stud is combined with nut, between described locating stud and nut, adaptation has jump ring 7 for axle, the upper lower limb of described flap valve core and flap valve body contacting point are provided with seal ring 4, and described seal ring is crimped with stainless steel platen 5 by bolt 8.
Jump ring 7 stuck bearing pin end for axle, prevents that flap valve core both sides from moving, and in order to make the work of axle jump ring good, can between axle is with jump ring and locating stud, adaptation have pad 6, strengthens the stability of axle use jump ring.
In order to strengthen the overall tightness of flap valve, can on flap valve body inwall, be connected with the wedge-shaped catch 9 coordinating with stainless steel platen inclined-plane, like this can be very fast in the time that flap valve is opened leave wedge-shaped catch, when static, can seal up the space between flap valve body and flap valve core, when flap valve is closed, can eliminate and weaken the impact force of flap valve core to flap valve body.The end of described wedge-shaped catch and seal ring close contact, the inside of described wedge-shaped catch offers the opening slot of level towards seal ring, the interior adaptation of described opening slot has the stage clip 10 with seal ring close contact, stage clip can further weaken the impact force of flap valve core to flap valve body, make the impact force between flap valve core and flap valve body reduce to minimum, strengthen the stability of overall flap valve.
The utility model can arrange wedge-shaped catch as above with the place that flap valve body top contacts at flap valve core, also can be with the place that flap valve body bottom contacts, wedge-shaped catch to be set at flap valve core, or flap valve core and flap valve body top, contacting point, bottom all arrange such wedge-shaped catch.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or without improving, design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
