Description
Technical field
The utility model belongs to mechanical equipment technical field, and in particular to a kind of abrator head.
Background technology
Blasting treatment can make workpiece surface obtain certain cleannes and different roughness, can effectively beautify workpiece outward appearance
With raising workpiece mechanical property, it has been applied successfully for many years in national economy and the industry-by-industry of national defense industry.At traditional sandblasting
The shortcomings that reason mode is dry type sandblasting, and its is maximum is that dust is produced in sandblasting procedures, causes dust pollution.Therefore, to tradition
Dry type sand-blasting machine transformed, make wet blast, avoid in sandblasting procedures produce dust pollution seem extremely heavy
Will.
Utility model content
The purpose of this utility model is：A kind of abrator head is provided and is used for dry type sand-blasting machine, enables to realize that wet type is sprayed
Sand.
To achieve the above object, the technical solution adopted in the utility model is as follows：
The utility model is mainly in charge of by shower nozzle, valve body, connecting tube, sandpipe, two points of elbow bends, one-way throttle valve, two
Joint, water-supply-pipe, valve core tube composition.The valve body both ends are provided with screw thread, and side is provided with two points of screwed holes, and one end passes through spiral shell
Line connects shower nozzle, and the other end is connected through a screw thread connecting tube, and two points of elbow bends of connection on screwed hole are divided in side two；The valve element
Pipe is arranged in valve body, and valve core tube one end is provided with annular groove, and 5 inclined holes are axially uniformly distributed on annular groove；To ensure
Spray gun sealing, is lined with sealing ring one between valve core tube and shower nozzle, and sealing ring two is lined between valve core tube and connecting tube；Institute
State one-way throttle valve one end to be connected with two points of elbow bends, the other end is in charge of joint by two or two and is connected with water-supply-pipe.
At work, water-supply-pipe is connected with high-pressure diaphragm pump, and sandpipe is connected with the blast tube of dry type sand-blasting machine.Water under high pressure with
The flow of one-way throttle valve can be adjusted into the inlet opening in one-way throttle valve, turn knob by water-supply-pipe；Work as turn knob
When rotating to a certain optimal flow status, water under high pressure impacts boss through inlet opening so that and spring-compressed, boss push, so as to
Water under high pressure is set to enter annular groove 19 by two points of elbow bends 6, and because the presence of inclined hole, water under high pressure enter in valve core tube；Spray
Sand material enters valve core tube by the blast tube of dry type sand-blasting machine through connecting tube and sandpipe so that water under high pressure contacts with blasting guardrail, real
The mixing of existing water and sand, sprays through shower nozzle, so as to realize the wet blast to workpiece.
The utility model is because being axially uniformly distributed 5 inclined holes on annular groove, so water and sand degree of mixing are high；This practicality
It is new to have used one-way throttle valve, water-carrying capacity can be not only controlled, is also prevented from siphon destructive caused by reverse current；This
Outside, the utility model shower nozzle, valve body, one-way throttle valve and connecting tube are all connected through a screw thread assembling, so that shower nozzle is being tieed up
Repair or change and be very convenient during parts.

Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in Fig. 1~Fig. 5, the utility model is mainly by 5, two points of shower nozzle 1, valve body 2, connecting tube 3, sandpipe elbow bends
6th, one-way throttle valve 7, two is in charge of joint 8, water-supply-pipe 9, valve core tube 13 and formed.The both ends of valve body 2 are provided with screw thread, and side is provided with
One two points of screwed hole, one end are connected through a screw thread shower nozzle 1, and the other end is connected through a screw thread connecting tube 3, and screwed hole is divided in side two
Two points of elbow bends 6 of upper connection；The valve core tube 13 is arranged in valve body 2, and the one end of valve core tube 13 is provided with annular groove 19, in ring
5 inclined holes 18 are axially uniformly distributed on connected in star 19；To ensure spray gun sealing, it is lined between valve core tube 13 and shower nozzle 1 close
Seal 1, sealing ring 2 12 is lined between valve core tube 13 and connecting tube 3；Described one end of one-way throttle valve 7 and two points of right angles
Elbow 6 connects, and the other end is in charge of joint 8 by two and is connected with water-supply-pipe 9.
At work, water-supply-pipe 9 is connected with high-pressure diaphragm pump, and sandpipe 5 is connected with the blast tube of dry type sand-blasting machine.Water under high pressure
With the inlet opening 14 that water-supply-pipe 9 enters in one-way throttle valve 7, turn knob 10 can adjust the flow of one-way throttle valve 7；When
When turn knob 10 rotates to a certain optimal flow status, water under high pressure impacts boss 15 through inlet opening 14 so that spring 17 is pressed
Contracting, boss 15 push, so that water under high pressure enters inlet opening 16；The water under high pressure that inlet opening 16 enters passes through two points of elbow bends 6
Into annular groove 19, and because the presence of inclined hole 18, water under high pressure enter in valve core tube 13；The spray that blasting guardrail passes through dry type sand-blasting machine
Sandpipe enters valve core tube 13 through connecting tube 3 and sandpipe 5 so that water under high pressure contacts with blasting guardrail, realizes the mixing of water and sand, through spray
First 11 spray, so as to realize the wet blast to workpiece.
The utility model is because being axially uniformly distributed 5 inclined holes 18 on annular groove 19, so water and sand degree of mixing are high；This
Utility model has used one-way throttle valve 7, can not only control water-carrying capacity, be also prevented from reverse current caused by siphon break
It is bad；In addition, the utility model shower nozzle 1, valve body 2, one-way throttle valve 7 and connecting tube 3 are all connected through a screw thread assembling, so that
Shower nozzle is very convenient when repairing or changing parts.
