Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic safety valves, in particular to a hydraulic safety valve. Background Art

[0002] The hydraulic safety valve is driven by compressed gas or liquid. Although the structure is complex, it has a large flow rate and high precision. Specifically, it uses the volume of high-pressure oil to generate a certain force, which pushes the piston or diaphragm to open or close the safety valve. Secondly, the working pressure of the hydraulic safety valve can be adjusted. By adjusting the oil volume, the hydraulic valve can automatically adjust the switching speed to adapt to changes in oil well pressure. In this way, it can maintain an efficient and stable working state in various working environments.

[0003] However, when the existing hydraulic safety valve is in use, the oil temperature of the hydraulic valve device is greatly affected by the ambient temperature. The change in oil temperature will cause the viscosity of the oil to change, which in turn affects the operation. For example, too high or too low oil temperature may cause the valve to be insensitive or fail. Therefore, we propose a hydraulic safety valve. Utility Model Content

[0026] like Figure 1-5 As shown, the utility model provides a technical solution: a hydraulic safety valve, including a hydraulic safety valve body 1, an oil storage chamber 4 is arranged on the top of the hydraulic safety valve body 1, a heating structure 2 is fixedly connected to the outer side of the oil storage chamber 4, the heating structure 2 can heat the hydraulic oil in the oil storage chamber 4, so that the hydraulic oil with too low temperature can reach the optimal use temperature, and a heat dissipation mechanism 3 is also connected to one side of the heating structure 2, the heat dissipation mechanism 3 can dissipate heat and cool down the heating medium in the heating structure 2 and the hydraulic oil in the oil storage chamber 4, so as to avoid the hydraulic oil in the oil storage chamber 4 being too high in temperature and affecting the hydraulic safety valve body 1 In order to ensure the working of the hydraulic oil storage chamber 4, a temperature sensor 5 is further provided inside the hydraulic oil storage chamber 4. The temperature sensor 5 can monitor the temperature of the hydraulic oil inside the hydraulic oil storage chamber 4 in real time. Through the design of the heating structure 2 and the heat dissipation structure, the temperature sensor 5 can detect the temperature of the hydraulic oil in real time. When the temperature of the hydraulic oil in the hydraulic oil storage chamber 4 is too low, the heating structure 2 will start and heat the hydraulic oil so that the hydraulic oil can be at an optimal working temperature. When the temperature of the hydraulic oil is too high, the heat dissipation mechanism 3 will start and synchronously dissipate the heat of the heating medium and the hydraulic oil inside the heating structure 2 so that it can be restored to the optimal working temperature.

[0027] Example 2

[0028] like Figure 1-5 As shown, the utility model provides a technical solution: the heating structure 2 includes a structural shell 21, a heating chamber 22 is opened inside the structural shell 21, a heating component 23 is fixed on the other side wall of the heating chamber 22, a heating rod 24 is provided at the output end of the heating component 23 and located inside the heating chamber 22, the heating component 23 can energize the heating rod 24 so that the heating rod 24 can heat the heating medium located inside the heating chamber 22, and the heating medium in the present application is water, so that the hydraulic oil in the heating chamber 22 can be heated more evenly, and the temperature sensor 5 will be connected to the PLC controller inside the heating component 23.

[0029] The heating assembly 23 is electrically connected to the heating rod 24 . A sealing partition plate 25 is also provided on a side wall of the structural shell 21 . The sealing partition plate 25 can separate the heating chamber 22 from the heat dissipation chamber 31 .

[0030] The heat dissipation mechanism 3 includes a heat dissipation chamber 31, a filter screen 32 is provided on the front of the heat dissipation chamber 31, a heat conduction plate 33 is provided at the bottom of the heat dissipation chamber 31, a plurality of heat dissipation fins 312 are provided on the top of the heat conduction plate 33 and located inside the heat dissipation chamber 31, a heat collecting seat 313 is provided at the connection of the heat conduction plate 33 and located inside the structural shell 21, the heat collecting seat 313 is fixed on the surrounding walls of the oil storage chamber 4 and fits with the oil storage chamber 4, and the heat conduction plate 33 runs through between the sealing partition plate 25 and the heat collecting seat 313 The heat sink 312 and the heat conducting plate 33 are connected to each other, and the heat dissipation fins 312 and the heat conducting plate 33 are designed as an integrated whole. The filter screen 32 can prevent the dust inside the heat dissipation chamber 31 from entering the mechanism housing 34 near the front. When heat dissipation is performed, the heating medium inside the heating chamber 22 and the hydraulic oil inside the oil storage chamber 4 will first transfer the heat to the heat collecting seat 313, and then the heat will be transferred through the heat conducting plate 33 to the heat dissipation fins 312 through the heat collecting seat 313, and the heat will be gathered at several heat dissipation fins 312.

[0031] The heat dissipation mechanism 3 also includes a mechanism shell 34, and connecting grooves 35 are provided on the front sides of the two mechanism shells 34 and the back side walls of the heat dissipation chamber 31. Limiting grooves 310 are provided inside the two mechanism shells 34 and near the front sides. Heat insulation plates 36 are provided inside the two limiting grooves 310. The heat insulation plates 36 are used to separate the space between the heat dissipation chamber 31 and the mechanism shell 34, so that when heat dissipation is not required, the heat inside the heat dissipation chamber 31 will not be dissipated to the outside through the connecting grooves 35, avoiding the problem that when the heating structure 2 is heated, heat will still be transmitted to the heat collecting seat 313, the heat conducting plate 33 and the heat dissipation fins 312, which will cause the heat to be dissipated to the outside if they are not blocked and protected. Therefore, a large amount of heat can always be kept inside the heat dissipation chamber 31 and the structure shell 21, thereby improving the heating effect and maintaining the temperature inside the heating cavity 22 and the oil storage chamber 4.

[0032] The bottom of the two mechanism housings 34 are fixedly connected with a fixed support 37, and the interior of the two fixed supports 37 is provided with a telescopic rod 38. The output ends of the two telescopic rods 38 are fixedly connected with a connecting rod 39, and the connecting rod 39 connects the telescopic rod 38 and the insulation board 36. The fixed support 37 can fix the telescopic rod 38 on the bottom of the mechanism housing 34. The extension of the telescopic rod 38 can drive the connecting rod 39 to move, and then drive the insulation board 36 to move in the limit groove 310, so that the partition is opened, so that the cooling fan 311 can be connected with the space inside the cooling chamber 31.

[0033] A cooling fan 311 is also provided at the center of the two mechanism housings 34, and a barrier net is also provided on the back side of the mechanism housing 34 near the back side, so that the back side of the cooling fan 311 near the back side can be connected to the outside world and dust can be blocked by the barrier net. The cooling fan 311 near the back side will send air to the inside of the cooling chamber 31 and dissipate heat for a number of cooling fins 312, while the other group of cooling fans 311 near the front will blow the hot air flow in the cooling chamber 31 to the outside. The two groups of cooling fans 311 can be used in conjunction with each other to greatly increase the air circulation rate and improve the heat dissipation effect.

[0034] The working process of the utility model: when using a hydraulic safety valve, step one: the temperature sensor 5 will detect the temperature of the hydraulic oil in real time. When the temperature of the hydraulic oil in the oil storage chamber 4 is too low, the heating structure 2 will start and heat the hydraulic oil. The heating component 23 can energize the heating rod 24 so that the heating rod 24 can heat the heating medium inside the heating chamber 22. The heating medium in this application is water, so that the hydraulic oil inside the heating chamber 22 can be heated more evenly. At the same time, the temperature sensor 5 will be connected to the PLC controller inside the heating component 23.

[0035] Step 2: When the temperature of the hydraulic oil is too high, the heat dissipation mechanism 3 will start and simultaneously dissipate the heat of the heating medium and the hydraulic oil inside the heating structure 2. The heat dissipation fan 311 near the back side will send air to the inside of the heat dissipation chamber 31 and dissipate heat for a number of heat dissipation fins 312, while another set of heat dissipation fans 311 near the front side will blow the hot air flow inside the heat dissipation chamber 31 to the outside. The two sets of heat dissipation fans 311 work together to greatly speed up the air circulation rate and improve the heat dissipation effect so that it can be restored to the optimal working temperature.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
