[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0017] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.
[0018] Combination Figure 2-3 As shown, it includes a cooling pipe a1, and both ends of the cooling pipe a1 are connected to a circulation pipe a2, and the characteristic is that: one end of the circulation pipe a2 is connected to an inlet pipe 1, and the other end is connected to an outlet pipe 2, a cooling water pool 12 is connected between the inlet pipe 1 and the outlet pipe 2, a pressure relief valve 3 and a flow meter 5 are connected on the inlet pipe 1, a flow pump 4 is provided on the outlet pipe 2, a one-way valve 13 is provided on the circulation pipe between the inlet pipe and the outlet pipe, and a pressure gauge (not shown in the figure) is also provided on the circulation pipe.
[0019] In the prior art, the cooling pipe in the cooling circulation system is affected by the cracking temperature for a long time, resulting in excessively high temperature in the cooling pipe, which will cause gas blockage. Figure 1 As shown in , at least one set of circulation pipes a2 are connected at both ends of the cooling pipe a1, and the liquid in the cooling pipe flows through the circulation pipe to achieve the purpose of cooling. Although this can also achieve the effect of cooling the cooling pipe, the gas in the cooling pipe cannot be discharged all the time, which will cause the water pressure in the cooling pipe to be too high and the cooling water flow to be blocked, affecting the cooling efficiency, and in serious cases, it will also cause safety hazards.
[0020] In order to solve the above problems, a cooling water pool is set at the corresponding position of the cooling pipeline, and a flow pump 4 is also provided on the outlet pipe, and a pressure pump (not shown in the figure) is provided on the circulation pipeline. In actual work, if the pressure in the circulation pipeline in the cooling circulation system is higher than the set value, the pressure relief valve will be opened. After that, the liquid flowing into the circulation pipeline first enters the cooling water pool, and the amount of the liquid is measured by a flow meter. Then, an equal amount of liquid is extracted by a flow pump and transported to the circulation pipeline through the outlet pipe. In this way, the gas in the cooling pipeline can be discharged, eliminating safety hazards, while also increasing heat exchange efficiency and reducing water resource waste. In this device, a pressure gauge is used to monitor the pressure in the circulation pipeline.
[0021] As a preferred structure, a pressure relief valve 3 is connected to the water inlet pipe 1, and the pressure relief valve 3 includes a valve body 31. The valve body 31 is respectively connected to a water inlet seat 32 and a water outlet seat 33 from bottom to top. A sealing seat 34 is fixed in the water inlet seat 32. A guide seat 35 is provided above the sealing seat 34 in the valve body 31. The sealing seat 34 is communicated with the water outlet seat 33. A sealing bowl 36 is provided downwardly in the guide seat 35. A guide block 37 is penetrated into the top of the valve body 31. A pressure relief rod 38 is penetrated in the guide block 37. A T-shaped rod 39 is connected to the bottom of the pressure relief rod. The T-shaped rod 39 penetrates into the guide seat 35 and is connected to the sealing bowl 36. A spring 310 is provided on the pressure relief rod 38 and between the guide block 37 and the T-shaped rod 39.
[0022] If the pressure in the circulation pipeline of the cooling circulation system is higher than the set value, the sealing bowl will move upward under the impact of water pressure, and the T-shaped rod will move upward accordingly. The spring will be gradually compressed until the sealing bowl is separated from the sealing seat. At this time, the sealing seat is connected to the water outlet seat, and the liquid enters from the water inlet seat of the pressure relief valve and flows out from the water outlet seat through the water inlet pipe into the cooling water pool for pressure relief. Until the water pressure in the cooling pipeline is no higher than the set value, the spring will recover its deformation, and under the action of the spring, the sealing bowl presses the sealing seat tightly, and the pressure relief valve is closed.
[0023] In this structure, the guide block guides the pressure relief rod, making it more stable during the up and down movement of the pressure relief rod. The sealing bowl is slidably arranged in the guide seat. During the opening / closing process of the pressure relief valve, the guide seat also guides the sealing bowl, making the sealing bowl more stable during the movement and having a better sealing effect.
[0024] As a preferred structure, Figure 5 An n-shaped frame 6 is provided on the top of the valve body 31, and a handle 7 is rotatably provided on one side of the n-shaped frame 6. An arc block 8 is formed upward in the middle of the handle 7. A threaded section is formed on the top of the pressure relief rod 38. A nut 9 is screwed into the top of the pressure relief rod after the gasket is inserted into the top of the pressure relief rod. The nut 9 presses the arc block 8 tightly.
[0025] If the pressure relief valve needs to be opened manually, the handle is pushed upwards at this time, and the pressure relief rod is pushed upwards by the arc block to move a short distance upwards. The pressure relief rod drives the sealing bowl upwards through the T-shaped rod, and the spring is gradually compressed. The sealing bowl is separated from the sealing seat, and the pressure relief valve is opened. In this device, the opening and closing of the pressure relief valve can also be controlled by setting a handle, so as to avoid the pressure relief valve not being able to be opened automatically by the spring. At this time, manual operation can be performed, thereby improving the safety of the device.
[0026] The handle 7 is provided with an avoidance groove 10, and the top of the n-shaped frame passes through the avoidance groove 10. The avoidance groove avoids the n-shaped frame, so that it can rotate along the height direction of the n-shaped frame, and the n-shaped frame guides the handle through the avoidance groove.
[0027] A stop block 11 is provided on the other side of the n-shaped frame 6 and below the handle 7. When the pressure relief valve is closed, the handle is supported on the stop block.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
