Specific embodiment

The utility model is described in detail below in conjunction with attached drawing.

As Figure 1-Figure 4, a kind of heat-resisting efficient blow-off valve, including valve body 100, spool 200, valve are present embodiments provided Valve 300, seal ring assembly and rotary joint 500, spool 200 penetrates through valve body 100, and valve body 100, valve are stretched out in 200 both ends of spool The junction of body 100 and spool 200 is sealed by seal ring assembly, and flap 300 is placed in valve body 100 and root is connected to spool On 200, spool 200 can drive flap 300 to rotate in valve body 100；The inside of spool 200 has the pipeline axially opened up, should Pipeline is circulation waterway 210, and the both ends of spool 200 are separately installed with rotary joint 500, which seals and valve The end of core 200 is rotatably connected, and the internal cavities of rotary joint 500 are connected to circulation waterway 210.

As shown in Figure 1,100 main body of valve body in the present embodiment is tubular structure, the two sides up and down of valve body 100 open up respectively The opening that material enters, and material pipe 110 is arranged in opening, the left and right sides of valve body 100 opens up axle center with always respectively Through-hole on line, the channel which installs as spool 200.When spool 200 is mounted in valve body 100, the left end of spool 200 Stretch out valve body 100 respectively with right end, it is possible to understand that, the joint face of spool 200 and valve body 100 goes out to be equipped with sealing device, is formed Air seal and dust particles sealing.Originally the spool 200 in implementing can be rotated, therefore be located at valve body 100 or so in spool 200 Two sides are symmetrically arranged support bearing, in order to which spool 200 is freely rotated.

The left and right ends of spool 200 are respectively arranged with rotary joint 500, and the effect of the rotary joint 500 is in spool 200 Connection, when spool 200 rotates, the water flowing space inside circulation waterway 210 and rotary joint 500 inside spool 200 is kept The junction of connection, the two keeps sealing.

When using this blow-off valve, material enters valve body 100, rotates band movable vane piece by spool 200 and rotates, forms effluent The effect of material, simultaneously, recirculated water enter in spool 200 from the rotary joint 500 of side, and recirculated water passes through spool 200 Afterwards, it is flowed out from the rotary joint of the other end 500, recirculated water takes away the heat that material distributes, so that this blow-off valve is maintained at lower Operating temperature.

This blow-off valve is by the circulation waterway 210 inside spool 200, and the rotary joint being arranged at 200 both ends of spool 500, spool 200 is docked with external water circulation device, cooling water carries out water cooling to spool 200, overcomes thermal material Influence of the high temperature conduction heat to equipment.

As shown in Fig. 2, rotary joint 500 includes that joint shell body 510, connector inner housing 520, bearing 530 and connector are close Seal 550, joint shell body 510, connector inner housing 520 main body be tubulose, being sleeved on for the end part seal of bearing 530 connects The outside of head inner housing 520, joint shell body 510 is sleeved on the outside of connector inner housing 520, and bearing 530 is arranged in connector Between inner housing 520 and joint shell body 510, the junction of connector inner housing 520 and joint shell body 510 passes through joint sealing 550 sealing of circle, joint shell body 510 are equipped with the opening entered for cooling water.

Specifically, the end of spool 200 is fixedly connected with connector inner housing 520, so that spool 200 and connector inner housing 520 can rotate synchronously, and connector inner housing 520 and joint shell body 510 are formed by bearing 530 and relatively rotated.Rotary joint 500 It is compact-sized, it can be achieved that rotation switching and being passed through two of recirculated water effects.

The oil filler point for adding lubricating oil to bearing 530 is offered on joint shell body 510.Oil filler point is in general state It is closed by plug down.

It is equipped between 520 inner wall of end and connector inner housing of connector inner housing 520 for buffering 200 axial vibration of spool Spring 540.Spring 540 plays the role of landing nipple inner housing 520 and spool 200,200 axial vibration of simultaneous buffering spool Effect.

As shown in Figure 1, the side of valve body 100 is equipped with 410 shell 400 of fan and fan 410, fan 410 are placed in fan 410 In shell 400,410 shell 400 of fan is equipped with the opening of air flowing, and fan 410 is connected to 200 outer circumference surface of spool and can It is rotated with spool 200, and the air-out direction of fan 410, towards the outer wall of valve body 100, fan 410 is used to carry out wind to valve body 100 It is cold.At 100 both ends of valve body, respectively arranged fan 410 can be carried out valve body 100 air-cooled in real time, overcome material pair in valve body 100 The radiant heat of bearing 530 is equipped with 2 radiator fans 410, effectively increases air flow amount, on the rotary shaft to take away Radiate thermogenetic heat.

410 shell 400 of fan and fan 410 have two groups, and two groups of 410 shells 400 of fan and fan 410 are symmetrically arranged on The two sides of valve body 100.By being piled so that heat distributes to 100 two sides of valve body while wind-cooling heat dissipating, and accelerate radiating efficiency.

As shown in figure 4,300 end bend of flap forms bending part 310, the overbending direction and flap 300 of the bending part 310 Direction of rotation it is opposite.Flap 300 in valve body 100 is 6 valves, and the end of each flap 300 uses arc transition, transition direction Direction of rotation with spool 200 is on the contrary, effective absorbing material thermal expansion, avoids the phenomenon that gets stuck generated because heated.

Valve body 100 is equipped with the material pipe 110 for material inlet-outlet valve body 100, inner wall, the valve body of material pipe 110 Gap between 100 inner wall and spool 200 forms the labyrinth structure for reinforcing air-tightness.Inner wall, the valve body of material pipe 110 Gap between 100 inner wall and spool 200 forms the labyrinth structure for reinforcing air-tightness, lengthens spool 200 in valve body 100 Coincidence amount and effectively form labyrinth seal, the leakage of dust and particulate matter is prevented with this.

The driving device 600 for driving spool 200 to rotate is additionally provided on spool 200, the driving device 600 setting is being faced The position of nearly rotary joint 500.

As shown in figure 4, position is by the hollow structure of recirculated water in spool 200, as shown, valve in the present embodiment Core 200 and flap 300 are to rotate clockwise, and the bending part of 300 end of flap is bent counterclockwise.100 interposition of valve body It is set to and the matched arcwall of 300 outer rim of flap.

The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality It, in specific embodiments and applications can be with many changes may be made, as long as these variations are without departing from this with novel thought The design of utility model, belongs to the protection scope of the utility model.
