Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example (b): a novel cooling structure of a thermal bypass valve is shown in figure 1 and comprises a long sleeve type three-way pipe joint 2, a metal pipe 3 and a straight-through pipe joint 5 which are connected end to end and are axially arranged along the inner cavity of a valve body. When the valve body is cooled, cooling air sequentially enters the long sleeve type three-way pipe joint 2, the metal pipe 3 and the straight-through pipe joint 5, and primary section cooling is completed through the long sleeve type three-way pipe joint 2; heat exchange is carried out through the metal pipe 3 to finish middle section cooling; the end cooling takes place via the through-connection 5.

Referring to fig. 1 and 2, a gas flowmeter 1 for calculating the air inflow is connected to one end of the long sleeve type three-way pipe joint 2, which is far away from the metal pipe 3, through a bent pipe, and the gas flowmeter 1 is arranged on the outer wall of the valve body. When the work begins, cooling gas firstly enters the gas flowmeter 1, and the gas flowmeter 1 feeds back the air inflow at the moment, so that the staff can know the relevant conditions and adjust the conditions conveniently.

Referring to fig. 1 and 3, the long sleeve type three-way pipe joint 2 is T-shaped, and the middle pipe orifice of the long sleeve type three-way pipe joint 2 is an air outlet which is axially perpendicular to the valve body. The cooling gas is sprayed out from the gas outlet, so that the cooling gas is led to two sides, and the purpose of uniform cooling is achieved.

Referring to fig. 1 and 4, a pipe clamp 4 is further arranged in the inner cavity of the valve body, a circular hole is formed in the center of the pipe clamp 4, and the diameter of the circular hole is the same as the outer diameter of the metal pipe 3. The metal pipe 3 passes through the pipe clamp 4, and the position of the metal pipe 3 is fixed by the pipe clamp 4, so that the metal pipe 3 is better attached to the thermal bypass valve, and the cooling effect is improved.

As shown in fig. 1 and 5 in conjunction, the through pipe joint 5 is close to the long axis of the thermal bypass valve, and the air outlet of the through pipe joint 5 is directed to the thermal bypass valve end. Finally, the cooling gas is sprayed out from the straight-through pipe joint 5 to cool the long shaft of the thermal bypass valve, so that the thermal bypass valve is prevented from being blocked by thermal expansion.

The specific implementation process comprises the following steps: firstly, cooling gas flows in from the gas flowmeter 1, and the gas flowmeter 1 feeds back the air inflow in real time, so that a worker can conveniently adjust the air inflow in real time. And then cooling gas passes through the long sleeve type tee pipe joint 2, gas is sprayed into the valve body through the gas outlet of the long sleeve type tee pipe joint 2 for cooling, then the cooling gas flows into the metal pipe 3, heat exchange is carried out through the metal pipe 3 to finish cooling, and finally the cooling gas is sprayed out from the straight-through pipe joint 5 for cooling.
