Problems solved by technology

[0006] Although this patent can maintain a certain tank pressure to reduce the volatilization of oil and gas, the vacuum pressure valve opens when the internal pressure of the oil storage tank is lower than the external pressure, and the inner and outer sides are directly connected, so that dust particles enter the oil storage tank with the external air, affecting the storage capacity. The quality of refined oil in the oil tank
At the same time, the existing vacuum pressure valve has the problem of low sensitivity, which makes it impossible to quickly recover the pressure in the tank when the pressure in the tank is abnormal, which in turn affects the quality of the oil in the tank

Embodiment 1

[0040] Embodiment 1. This embodiment discloses a vacuum pressure valve for an oil storage tank in a gas station, such as Figures 1 to 7 As shown, it includes a vacuum pressure valve housing 1, a disc cap 2 located on the upper and lower sides of the vacuum pressure valve housing 1, and a fixed sleeve 3. The lower end of the fixed sleeve 3 is provided with a connection port 4 connected to the oil storage tank. , the housing 1 of the vacuum pressure valve is provided with a fixed bracket 5 and a housing notch 11 adapted to the fixed bracket 5, the housing notch 11 communicates with the fixed sleeve 3, and the fixed bracket 5 is interspersed with a The pressure adjusting plate 6 that can slide up and down, the side of the fixed bracket 5 is provided with a number of evenly distributed ventilation slots 51, the outer cover of the fixed bracket 5 is provided with a first filter mesh structure 7 that matches it, the pressure adjusting plate 6 is The cylindrical structure is set, an...

Embodiment 2

[0051] Embodiment 2, the difference between this embodiment and Embodiment 1 is that, if Figure 8 As shown, the structure of the first filter screen structure 7 and the second filter screen structure 8 is the same, and the first filter screen structure 7 includes a filter paper layer 71 and a metal filter layer 72 positioned on both sides inside and outside the filter paper layer 71; The layer 71 can prevent the oil in the oil storage tank from spilling out of the oil storage tank, improve the air quality around the oil storage tank, and prevent the oil and gas in the air around the oil storage tank from easily causing a fire.

[0052] In summary, the present invention has the following beneficial effects:

[0053] 1. When the internal pressure of the oil storage tank is too high, the pressure regulating plate 6 overcomes its gravity and slides upwards, so that the internal pressure of the oil storage tank is discharged from the ventilation slot 51, otherwise it moves downwar...

Abstract

The invention discloses a vacuum pressure valve for an oil storage tank of a gas station. According to the main points of the technical scheme, the vacuum pressure valve comprises a vacuum pressure valve shell, a disc cap and a fixing sleeve, wherein the disc cap and the fixing sleeve are located at the upper side and the lower side of the vacuum pressure valve shell; a fixing support and a shell notch matched with the fixing support are arranged in the vacuum pressure valve shell; a pressure adjusting plate capable of sliding up and down is arranged in the fixing support in a penetrating manner; a plurality of ventilation notches are formed in the side surface of the fixing support; the outer side of the fixing support is covered with a first filter screen structure matched with the fixing support; an adjusting groove is formed in the bottom of the pressure adjusting plate; an adjusting rod sliding up and down is arranged in the adjusting groove in a penetrating manner, and the lower end of the adjusting rod is fixedly connected with an adjusting piston; a plurality of adjusting through holes are further formed in the adjusting groove; and the upper side of the adjusting rod is sleeved with an elastic support matched with the pressure adjusting plate. The vacuum pressure valve has the advantages of being simple in structure, stable in tank pressure and high in reliability, effectively filters impurities in air and avoids the influence on oil quality.

Description

technical field [0001] The invention relates to the technical field of petrochemical equipment, in particular to a vacuum pressure valve for oil storage tanks in gas stations. Background technique [0002] Vacuum pressure valve, that is, vacuum pressure release valve, is a protective device used on the top of powder storage bins in industries such as thermal power generation, building materials, metallurgy, and chemical industry. Protects silos from excessive positive and negative pressures during inflation and degassing and abnormal temperature changes. [0003] The vacuum pressure valve for the oil storage tank of the gas station oil depot consists of two parts: a pressure valve and a vacuum valve. Installed at a height of about 4.5 meters from the vent pipe of the oil storage tank, its function is to maintain the tightness of the oil tank under normal circumstances and reduce the evaporation loss of oil products to a certain extent. And when necessary, it can automatica...
