Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.
[ example 1 ]
As shown in fig. 1, the embodiment discloses a capillary flow regulating device, including capillary connection pipe 1, channel valve 2, capillary integrated end 3, capillary connection pipe 1 includes capillary connection pipe flaring 11, capillary connection pipe main pipe 12, threaded connection head 13 and channel valve 2 threaded connection, threaded connection head 13 is close to capillary main pipe 12 one side and is provided with the sealing washer, channel valve 2 is the round platform shape structure, the one side that the channel valve 2 sectional area is big is provided with through-hole 21, the one side that the channel valve sectional area is big is connected with capillary integrated end threaded connection, capillary integrated end includes connecting seat 31, channel pipeline 32, capillary flaring 33, connecting seat 31 is connected with the one side that the channel valve 2 sectional area is big, connecting seat 31 is provided with the sealing washer close to channel pipeline 32 one side, the inside circumference evenly distributed of connecting seat 31 has channel pipeline 32, channel pipeline 32 and capillary flaring 33 fixed connection, channel pipeline 32 and channel valve 2 through-hole intercommunication.
When the device is installed and used, in a test preparation stage, a capillary tube of refrigeration equipment to be tested is cut off, capillary tube flow regulating devices are installed at two ends of the cut capillary tube in a mirror symmetry mode, a capillary tube connecting pipe flaring 11 is connected with an original capillary tube of the refrigeration equipment to be tested during installation, a threaded connector 13 is in sealing connection with one end of a channel valve 2 through threads and a sealing ring, one end connecting seat 31 of the channel valve 2 with a through hole 21 is in threaded sealing connection, a capillary tube flaring 33 is connected with capillary tubes of different specifications, the other ends of the capillary tubes of the different specifications are connected with a capillary tube flaring of another capillary tube flow regulating device, and it is noted that the capillary tube is inserted and then further welded after the capillary tube flaring 11 and the capillary tube flaring 33 are connected with the capillary tube, and the sealing performance is enhanced.
When the flow is regulated, the channel valves on two sides need to be simultaneously screwed, and the through holes on the channel valves are aligned to the capillary tubes with different specifications of the channel pipelines, so that the specifications of the capillary tubes can be changed. When in adjustment, the sealing function of the sealing ring has a certain elastic range, the channel valve can be screwed for 2-3 circles within the elastic range, and when the channel valve is screwed for 2-3 circles, the elastic range of the sealing ring is about to exceed, the sealing function cannot be achieved, or the sealing ring is extruded to the limit and is difficult to screw, the channel valve is screwed in the opposite direction to perform capillary switching.
The mode has simple structure and low cost, and the sealing ring can be replaced regularly to ensure the sealing effect.
[ example 2 ] A method for producing a polycarbonate
The structure of the embodiment is basically the same as that of the embodiment 1, and the difference is that rotary joints are arranged at two ends of the channel valve 2 and are connected with the capillary connecting pipe and the capillary integrated end through the rotary joints.
When the actual flow operation of adjusting, twist the passageway valve of moving both sides simultaneously, because passageway valve both ends all set up rotary joint, rotary joint itself can play the rotary seal effect, when twisting the passageway valve, need not to consider the problem of the elasticity scope of sealing washer.
