It is rotated under effect towards air inlet section direction, realizes the effect of block air inlet section outlet, realize that air-flow is only capable of from air inlet section to out with this
The effect of gas section single effect, avoids dust from inversely entering, improves dust removing effects.
Detailed description of the invention
Fig. 1 is the positive structure diagram of an embodiment of the present invention；
Fig. 2 is the structural schematic diagram of the inside of an embodiment of the present invention；
Fig. 3 is the structural schematic diagram of the baffle of an embodiment of the present invention.
Specific embodiment
With reference to the accompanying drawing and embodiment is described in further detail the utility model.
As shown in Figure 1, Figure 2 and shown in Fig. 3, a kind of sandblasting check-valves for burr machine, including rounded hollow air inlet section
1, described 1 one end of air inlet section is arranged with valve seat 2, and the valve seat 2 includes horizontal platform 21 and extended segment 22, and the horizontal platform 21 is vertical
In a ring in 1 outside of air inlet section, the extended segment 22 is connected with perpendicular to 21 outer of horizontal platform, the extended segment 22
Air outlet section 3 offers connecting hole 23 on the extended segment 22 in the horizontal direction, baffle 4 is hinged in the connecting hole 23, described
The connecting end surface of air inlet section 1 is higher than the horizontal platform 21, and the connecting end surface of the connecting hole 23 and the air inlet section 1 is positioned at same
On horizontal plane.
In sandblasting procedures, air inlet section 1 is under pressure increase, and baffle 4 by connecting hole is hinged on prolonging for valve seat 2 due to side
It stretches in section 22, therefore is rotated under pressure along hinged place, i.e., gas and sandblasting can go out to carry out burr removing from air outlet section 3
Sandblasting procedures are recycled in operation, and pressure disappears, and baffle 4 rotates under the action of 3 air pressure of air outlet section towards 1 direction of air inlet section, realize envelope
The effect that air inlet section 1 exports is locked, realizes that air-flow is only capable of avoiding dust from air inlet section 1 to the effect of 3 sections of single effects of outlet with this
It is reverse to enter, improve dust removing effects.
Baffle 4 is articulated in connecting hole 23, and the height of connecting hole 23 and the connecting end surface of air inlet section 1 are located at same level
On, then maintain an equal level when baffle 4 is closed by reversed air pressure with the connecting end surface of air inlet section 1, is conducive to its sealing effect.The company of air inlet section 1
Contact surface is higher than horizontal platform 21, so that baffle 4 is directly contacted with the connecting end surface of air inlet section 1 when being closed, increases sealing effect.Its
The connecting end surface of middle air inlet section 1 refers to the top surface of 1 connecting valve seat of air inlet section, 2 side.
The baffle 4 includes the connecting rod 41 being rotationally connected in the connecting hole 23, institute in one of the embodiments,
It states 41 by-level of connecting rod and is extended with link block 42, the link block 42 is far from 41 side of connecting rod integrally formed with circle
The block 43 of shape, the outer diameter of the block 43 are greater than the internal diameter of the air inlet section 1.Connecting rod 41 rotates in connecting hole 23, band
The dynamic link block 42 being attached thereto and block 43 rotate, and link block 42 is arranged, convenient for encountering extended segment 22 when the rotation of block 43
Inner wall.When air inlet section 1 stops ventilating, block 43 can rotate the connecting end surface of closing air inlet section 1 towards air inlet section 1, only keep off
The internal diameter that the outer diameter of block 43 is greater than air inlet section 1 is just able to achieve the technical effect of closing air inlet section 1.
The outer diameter of the block 43 is less than the internal diameter of the air outlet section 3 in one of the embodiments,.1 air inlet of air inlet section
When block 43 by effects of air pressure towards 3 direction of air outlet section rotate, if 43 outer diameter of block be not less than air outlet section 3 internal diameter, block
3 internal diameter of air outlet section can be encountered in 43 rotation processes, influence to ventilate.
42 two sides of link block are perpendicular to the connecting rod 41 in one of the embodiments,.
The air outlet section 3 is connected with installation part 5, the installation far from described 2 one end of valve seat in one of the embodiments,
Connector 51 is equipped with along inner wall direction convex among part 5.Connector 51 along the outside projection in inner wall direction facilitates connection equipment
In pipeline.
