Description
Technical field
This utility model relates to a kind of check-valves, particularly relates to a kind of fast loaded check valve for sewage discharge.
Background technology
The effect of check-valves is to prevent the medium in pipeline from flowing backwards, and is mainly used on the pipeline of medium one-way flow, only permits
Permitted medium to flow to a direction, to try to avert accidents.Often using check-valves during sewage discharge, it is made
Prevent sewage suck-back with being primarily used to, affect the normal work of waste removal equipment.But, for sewage discharge in prior art
Check valve structure is the most more complicated, the situation of blocking easily occurs, and check-valves is inconvenient to clear up after blocking, this
The process assembled after outer cleaning needs to take a substantial amount of time, the normal work of strong influence waste removal equipment.
To this end, it is proposed that a kind of fast loaded check valve for sewage discharge solves the problems referred to above.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and the one proposed is arranged for sewage
The fast loaded check valve put.
To achieve these goals, this utility model adopts the technical scheme that
A kind of fast loaded check valve for sewage discharge, including valve body and the adpting flange being arranged on valve body two ends, described
The inside of valve body is provided with ring-shaped step, and the upper end of described valve body is provided with opening, and the upside of opening is provided with sealing lid, and seals lid
Being fixedly connected on valve body by screw, the described lower end sealing lid connects sleeve, and the inside of sleeve is provided with rotating shaft, and turns
The two ends of axle are rotationally connected with the inwall of sleeve, and described rotating shaft is arranged with torque spring, one end of described torque spring and set
The inwall of cylinder offsets, and the other end of torque spring offsets with the limited block on the inwall of sleeve, fixing connection in described rotating shaft
Having baffle plate, and baffle plate lower end offsets bottom body cavity, described baffle plate is provided with sealing gasket near the side of ring-shaped step, and close
Packing offsets with ring-shaped step.
Preferably, the inwall of described valve body and sleeve is equipped with corrosion-resistant coating.
Preferably, the inner chamber of described valve body is four-prism structure, and the two ends of body cavity are respectively connected with rounded transitional
Pipeline.
Preferably, described baffle plate is inclined to set, and the angle of inclination of baffle plate is 15-45 degree.
Compared with prior art, the beneficial effects of the utility model are: by sealing the lower end branch sleeve of lid, at set
Rotating shaft is set on Tong, and baffle plate is connected in rotating shaft, the non-return structure of valve inner can be taken out by unloading lower sealing cover,
The most quickly assembling, the non-return structure being simultaneously made up of torque spring, rotating shaft and baffle plate is not only convenient for clearing up, and
And can individually be replaced after being corroded by sewage long period of soaking, shorten the maintenance time of check-valves, also reduce dimension simultaneously
The cost protected.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of fast loaded check valve for sewage discharge that the utility model proposes.
In figure: 1 valve body, 2 adpting flanges, 3 screws, 4 seal lids, 5 sleeves, 6 torque springs, 7 rotating shafts, 8 ring-shaped steps, 9

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
With reference to Fig. 1, a kind of fast loaded check valve for sewage discharge, including valve body 1 and the connection being arranged on valve body 1 two ends
Flange 2, the inner chamber of valve body 1 is four-prism structure, and the two ends of valve body 1 inner chamber are respectively connected with rounded transitional pipeline, valve body 1
Inside is provided with ring-shaped step 8, and the upper end of valve body 1 is provided with opening, and the upside of opening is provided with sealing lid 4, and sealing lid 4 passes through spiral shell
Nail 3 is fixedly connected on valve body 1, and the lower end connection sealing lid 4 has sleeve 5, and the inwall of valve body 1 and sleeve 5 is equipped with anticorrosion
Layer, the inside of sleeve 5 is provided with rotating shaft 7, and the inwall of the two ends of rotating shaft 7 and sleeve 5 is rotationally connected, and rotating shaft 7 is arranged with torsion
Spring 6, one end of torque spring 6 offsets with the inwall of sleeve 5, and the limit on the inwall of the other end of torque spring 6 and sleeve 5
Position block offsets, and rotating shaft 7 is fixedly connected with baffle plate 10, and baffle plate 10 is inclined to set, and the angle of inclination of baffle plate 10 is 15-45
Spending, and baffle plate 10 lower end offsets with valve body 1 intracavity bottom, baffle plate 10, torque spring 6 and rotating shaft 7 form the non-return knot of check-valves
