[0002] A steam trap is a device specifically designed to discharge condensate and air while preventing steam from escaping. Its primary function is to automatically remove steam condensate and non-condensable gases such as air from heating equipment or steam pipes, preventing steam condensation and energy loss. Steam traps are widely used in various steam systems, such as power plants, chemical plants, and food processing industries. Medium and high-pressure steam traps operate at pressures of 1.0 MPa and above and are suitable for industrial environments requiring high pressure.

[0003] Existing steam traps are only installed on pipelines for use. Two sealing rings cannot be placed in the valve body to increase the sealing effect of the valve. The steam trap cannot be quickly installed and disassembled to facilitate subsequent replacement and maintenance by workers, which may cause damage to fixed equipment. The high surface temperature of the valve cannot be reduced, which may cause burns to personnel. The heat generated by the valve in the protective shell cannot be quickly removed. The equipment support cannot be quickly enhanced to enhance the stability of the equipment. Therefore, a utility model is proposed to solve the above problems. Utility Model Content

[0015] In summary, the technical effects and advantages of the utility model are:

[0016] 1. The utility model has a reasonable structure. By installing the first sealing ring and the second sealing ring in the upper valve body, a double-layer sealing effect is formed to make the sealing effect of the valve better. The protective base is fixed under the fixed component, and the isolation gasket is sleeved under the lower valve body. The fixed component is fixed under the lower valve body, and can be quickly installed and disassembled on the lower valve body, which is convenient for workers to replace equipment in the later stage.

The support rod rotates and opens on one side of the protective shell to support the ground. On the smooth ground, the vacuum pump rotates to extract the air in the support suction cup and removes it. A vacuum is formed in the support suction cup and it is fixed by adsorption to the ground, quickly supporting the equipment, enhancing the stability of the equipment, and reducing the shaking of the equipment caused by accidental contact by people, which affects its use.

The protective cover 11 is quickly installed and removed from the protective shell 9 through the protective bolts 901. The heat dissipated by the upper valve body 1 and the lower valve body 2 in the protective shell 9 is removed through the heat sink 10. When the temperature in the protective shell 9 is too high, the fan 12 on the protective cover 11 rotates to quickly extract the hot air in the protective shell 9. , the support motor 802 drives the support rod 803 to rotate, so that the support rod 803 rotates on one side of the protective shell 9 to open the ground for support. When in use, on a smooth ground, the vacuum pump 804 rotates to extract the air in the support suction cup 805 for exhaust, so that a vacuum is formed in the support suction cup 805 and it is adsorbed and fixed to the ground, which can quickly support the equipment. This equipment adds a seal to form a double-layer seal effect, which makes the valve sealing effect better and the movement more sensitive. It can be quickly installed and disassembled on the lower valve body 2, which is convenient for workers to replace equipment later. The temperature of the surface of the lower valve body 2 is isolated by the isolation pad 3, which reduces the surface temperature of the lower valve body 2 being too high during operation, causing damage to the fixing component 4 and making it unusable, and reduces the situation where the surface temperature of the upper valve body 1 and the lower valve body 2 is too high, and people accidentally touch it and cause scalding to people, and reduces the heat in the protective shell 9 cannot be quickly discharged, resulting in excessive temperature affecting the service life, and can quickly support the equipment, enhance the stability of the equipment, and reduce the shaking of the equipment caused by accidental touch by people and affect its use.
