Abstract

The invention discloses a new structure of a cooling water flow distributor for an accelerator. Its core component is the water flow regulating device, which includes a welded base, a throttle plate, a sealing O-ring, and a welded pipe. The throttle plate is placed in the groove at one end of the welding base and sealed by the sealing O-ring. This water flow regulating device relies on adjusting the aperture size of the throttle plate to adjust the cooling water flow. While ensuring a constant flow rate, the volume of the cooling water flow distributor is reduced to a certain extent, saving space.

Description

Cooling water flow distributor for accelerator

technical field

The invention belongs to the technical field of accelerators, and in particular relates to a new structure of a cooling water flow distributor for accelerators.

Background technique

Non-destructive testing using X-ray projection imaging technology has been widely used in the non-destructive testing industry. An important factor that affects the stability of the detection dose rate and the life of the flaw detection accelerator is the cooling system. When the X-ray head is required to be compact, the cooling water flow distributor used in the cooling system should not be too large. In the prior art, the cooling water flow distributor used in the cooling system is regulated by a valve, which has the problems of large volume and easy damage to the adjusted value.

Contents of the invention

The invention aims at the problems existing in the existing cooling water flow distributor for accelerators, and provides a cooling water flow distributor with small volume, constant flow rate and difficult misoperation.

A cooling water flow distributor, comprising a water separator block, the water separator block is respectively connected to a cooling water inlet pipe and a water outlet pipe, and the cooling water inlet pipe and the water outlet pipe are connected to a load through a water flow regulating device. The key point is that the water flow regulating device includes a welding base, a throttling piece, a sealing O-ring, and a welding connecting pipe, wherein one end of the welding base is connected to the cooling water inlet pipe, and the throttling piece is placed in the groove at the other end of the welding base. And it is sealed by the sealing O-ring, and the welded connecting pipe squeezes the throttling piece and seals the O-ring through the fastening nut, and connects the welding base and the welded connecting pipe.

The above-mentioned water flow regulating device adjusts the flow rate of cooling water by adjusting the aperture size of the throttling plate, and different cooling water flow rates can be obtained by using throttle plates with different apertures, thereby providing different cooling capacities for different loads. Since the throttling plate is small in size and placed in the water flow regulating device, misoperation will not occur. Under the condition of ensuring constant flow, the volume of the cooling water flow distributor is reduced to a certain extent, saving space.

Detailed ways

The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, a cooling water flow distributor, its main body is a water separator block 3, the water separator block 3 is fixed through the fixing hole 5, and connected to the cooling water inlet pipe 2 and outlet pipe 1 respectively , There is no connection between the cooling water inlet pipe 2 and the outlet pipe 1. The cooling water inlet pipe 2 is provided with a plurality of water inlet holes 6, and the water outlet pipe 1 is provided with a plurality of water outlet holes 4, and the water inlet holes 6 and the water outlet holes 4 are connected to a load through a water flow regulating device.

As shown in Figures 3 and 4, the water flow regulating device includes a welding base 10, a throttle plate 9, a sealing O-ring 8, and a welding connecting pipe 7, wherein one end of the welding base 10 is connected to the water inlet 6 by welding, and the other end is provided There is a groove, the throttling piece 9 is placed in the groove, and is sealed by the sealing O-ring 8 , the welded connecting pipe 7 squeezes the throttling piece 9 and the sealing O-ring 8 through the fastening nut 11 , and is connected with the welding base 10 .

The welded connecting pipe 7 is connected to the load through the pipeline, and the cooling water flowing out from the load flows back to the water outlet pipe 1 through the water outlet hole 4, and circulates.

During use, first determine the hole diameter of the flow sheet 9 according to the size of the flow rate and then process and shape it. The specific determination method is as follows:

Step 1, experimentally measure the flow rate to determine the aperture of the throttling plate 9 . In the water distributor, respectively use throttle plates 9 with estimated pore diameters, and connect flowmeters in series, record the pressure and flow, replace the throttle plates according to the value of the flow rate, and determine the best throttle of each branch several times. Tape-out9.

In step 2, the installation of the throttling pieces 9 of each branch is completed. Remove the flow meter, assemble the water flow regulating device, and complete a set of cooling water flow distribution system.
