Description
Technical field
The utility model relates to the fields of valve, and in particular to sand valve.
Background technique
It is domestic at present for adjusting the device of abrasive material (also referred to as sand) flow, more there are commonly gate valve and butterfly valve this two
Kind, but the service life of both valves is not grown generally, and not high to the control precision of sand flow amount, influences the quality of abrasive material, and this
Two kinds of valves have more than is needed how long will there is a phenomenon where sand leakages, to guarantee its normal use, need often to be maintained, and this
Lead to the problem that production efficiency is low, it is unsatisfactory.
Utility model content
In view of the deficiency of background technique, the utility model is there is provided a kind of sand valve, and how is technical problem to be solved
The flow that shakes out is adjusted in real time, and is precisely controlled the flow that shakes out.
To realize the above-mentioned technical purpose, the utility model provides following technical solution:
Sand valve, it is characterised in that: the valve body including tubular is separately installed with first end cover and at the both ends of the valve body
Two end caps are equipped with screw rod in the valve body, and described screw rod one end is rotatably installed in the first end cover, the other end with it is described
Second end cover rotation connection, and be pierced by the second end cover and connect with servo motor transmission, lower sand is additionally provided on the valve body
Mouth, air inlet and the outlet of sand gas, the lower sand mouth are set relatively close to the second end cover, the sand gas outlet and the air inlet
It sets simultaneously close to the first end cover, to be also connected on the valve body and exports the sand gas mixing vessel communicated, institute with the sand gas
The outlet end for stating sand gas mixing vessel is connected with sand tracheae, is provided with ball valve on the sand tracheae.
The screw rod is four line screw rods.
The air inlet is connected with air inlet pipe, is connected with compressed air in the air inlet pipe.
The size that the import of the sand gas mixing vessel is exported with the sand gas matches, the sand gas mixing vessel into
The internal diameter of mouth is greater than the internal diameter of the outlet.
The ball valve is manual ball valve.
Possessed beneficial effect is the utility model compared with prior art: driving screw rod to be turned using servo motor
It is dynamic, so that the sand in valve body be made to flow with the rotation of screw rod, and finally flowed in sand tracheae from the outlet of sand gas mixing vessel,
And switching function is realized by the ball valve on sand tracheae, whole process is simple, and the structurally reasonable precision of product overcomes sand leakage
Defect.Meanwhile reasonable sand gas mixing ratio can be set by being passed through compressed gas, effectively improve the quality of abrasive material.In addition, passing through
Control servo motor revolving speed can in real time, be accurately controlled the flow of sand valve, it is highly reliable, the quality of abrasive material is effectively ensured.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, sand valve, the valve body 1 including tubular are separately installed with first end cover 11 at the both ends of the valve body 1
With second end cover 12, screw rod 2 is equipped in the valve body 1, in the present embodiment, the screw rod 2 is four line screw rods.The screw rod
2 one end are rotatably installed in the first end cover 11, and the other end and the second end cover 12 are rotatablely connected, and are pierced by described second
End cap 12 and servo motor 3 are sequentially connected, and lower sand mouth 13, air inlet and the outlet of sand gas are additionally provided on the valve body 1, under described
Sand mouth 13 is connected close to the second end cover 12 with sand-blasting machine, and the air inlet is connected with air inlet pipe 7, the air inlet pipe 7
Inside be connected with compressed air, compressed air can mix with sand and be formed the abrasive material of certain sand gas ratio, the sand gas outlet and it is described into
Port is oppositely arranged and close to the first end cover 11, is also connected on the valve body 1 and exports the sand communicated with the sand gas
The outlet end of gas mixing vessel 4, the sand gas mixing vessel 4 is connected with sand tracheae 5, is provided with ball on the sand tracheae 5
Valve 6, in the present embodiment, the ball valve 6 are manual ball valve.
It is ejected to guarantee that abrasive material can be concentrated after sand gas mixing vessel 4 with speed appropriate, the sand gas mixing is held
The size that the import of device 4 is exported with the sand gas matches, and the internal diameter of the import of the sand gas mixing vessel 4 is greater than the outlet
Internal diameter.
Working principle is as follows:
The revolving speed of abrasive material flow real-time control servo motor 3 as needed, sand pass through lower sand mouth 13 from sand-blasting machine ejection
Into in valve body 1, and servo motor 3 drives screw rod 2 to rotate, thus flow the sand in valve body 1 with the rotation of screw rod 2, when
When sand flow to sand gas outlet, since air inlet has been passed through compressed air, which will be mixed to form abrasive material with sand, and
Enter in sand gas mixing vessel 4 commonly through the outlet of sand gas, final abrasive material flows to sand tracheae 5 from the outlet of sand gas mixing vessel 4
In, when the ball valve 6 on sand tracheae 5 is in the open state, abrasive material just flows out from the nozzle of sand tracheae 5 and carries out sandblasting.
To sum up, the structurally reasonable precision of the utility model, overcomes the defect of sand leakage.Meanwhile it can by being passed through compressed gas
Reasonable sand gas mixing ratio is arranged, the quality of abrasive material is effectively improved.In addition, can be real by the revolving speed of control servo motor 1
When, be accurately controlled the flow of sand valve, it is highly reliable, the quality of abrasive material is effectively ensured.
