Description

Technical Field

[0001] The invention relates to the technical field of valves, and in particular to a gas pressure regulating valve assembly. Background Art

[0002] The gas distribution pipelines are divided into different pressure levels during the transmission and distribution process. Since the upstream pressure in the distribution system is higher and the pressure required on the user side is lower, the gas needs to be reduced and stabilized from the medium and high pressure pipelines through a pressure regulator before it can be supplied to users. This requires the use of pressure reducing equipment to reduce the pressure, otherwise household gas appliances will not be able to withstand the high pressure and there will be risks in use.

[0003] However, reducing the gas pressure will lead to reduced gas fluidity, especially in cold winter weather. Since the gas contains a small amount of moisture and other substances that can condense in a low-temperature environment, when the pressure regulating valve does not work for a long time, these condensable substances will condense in the gaps between the pressure regulating valve components, making it difficult to open the pressure regulating valve, especially when it works for the first time after a long period of non-operation, affecting the normal use of the gas. Therefore, we propose a gas pressure regulating valve assembly that can preheat the pressure regulating valve in a low-temperature environment to ensure the normal use of the pressure regulating valve in a low-temperature environment.

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 9As shown, the present embodiment proposes a gas pressure regulating valve assembly, including a pressure regulating valve 1, a diverter chamber 2 and an air inlet joint 3. In a scene where multiple stoves are required, such as a restaurant kitchen, multiple pressure regulating valves are required to meet different gas usage requirements. A single pressure regulating valve is difficult to meet different cooking requirements. Therefore, multiple pressure regulating valves 1 are arranged on the diverter chamber 2, so that the multiple pressure regulating valves 1 are connected to the corresponding stoves to supply gas thereto, meeting different gas pressure requirements. The present invention also includes a heating mechanism and an air supply assembly. Compared with the gas pressure regulating valve assembly in the prior art, the present invention uses a fan 201 to supply gas to the inner of the heating chamber 102. The air is supplied from the heater 105, and the hot air enters the interior of the heating chamber 101 to heat the diverter chamber 2 and the pressure regulating valve 1, so that the condensed materials in the fuel gas are melted, thereby ensuring the normal use of the pressure regulating valve 1 assembly. The two cleaning cylinders 301 are driven to rotate by the driving shaft 402, and the filter plate 302 in the working position filters the impurities in the fuel gas to ensure the cleanliness of the fuel gas entering the pressure regulating valve 1. The blowing pipe 501 purges the filter plate 302 that is not in the working position, and the impurities fall into the dust collecting chamber 502 for collection, thereby ensuring the filtering and impurity removal effect of the filter plate 302.

[0023] The heating mechanism is used to heat the diverter bin 2 and the pressure regulating valve 1. The heating mechanism includes a heating bin 101 and a heating bin 102. The heating bin 101 is fixedly connected to the diverter bin 2. The heating bin 101 is connected with an air inlet pipe 103 and an air outlet pipe 104. A heater 105 is installed inside the heating bin 102. The heating bin 101 is connected with the heating bin 102 through the air inlet pipe 103. The air in the heating bin 102 is heated by the heater 105. The hot air enters the interior of the heating bin 101 through the air inlet pipe 103. The hot air heats the heating bin 101. The heating bin 101 transfers heat to the diverter bin 2 and the pressure regulating valve 1 to melt the condensed material in the pressure regulating valve 1, thereby ensuring the normal opening of the gas pressure regulating valve assembly.

[0024] The air supply component is used to supply air to the heating mechanism, and the air supply component includes a fan 201. The air outlet of the fan 201 is connected to the heating chamber 102. The fan 201 supplies air to the interior of the heating chamber 102. The heater 105 heats the air. At the same time, the fan 201 pushes the hot air to the interior of the heating chamber 101 to ensure the heating effect on the diversion chamber 2 and the pressure regulating valve 1. The air inlet of the fan 201 can be connected to the exhaust hood so that the exhaust hood is in the position of the stove. The heat generated by the combustion of the stove can be transferred to the interior of the heating chamber 102, thereby further improving the heating effect.

[0025] In order to improve the heating effect of the heating chamber 101, a partition 4 is fixedly connected to the inside of the heating chamber 101, and the partition 4 is located between the air inlet pipe 103 and the air outlet pipe 104.

The heat inside the heating chamber 101 is transferred to the outside through the heat conducting plates 5, and the diversion chamber 2 and the pressure regulating valve 1 are quickly heated, and the melting speed of the gas in the pressure regulating valve 1 is accelerated. At the same time, the heat conducting plates 5 have a certain blocking effect on the hot gas in the heating chamber 101, further extending the time of the hot gas in the heating chamber 101 and improving the heating effect.

[0027] In order to improve the heating effect on the pressure regulating valve 1, the air outlet pipe 104 is connected to multiple hot air pipes 6, and the hot air pipes 6 correspond to the pressure regulating valve 1 one by one. The air outlet of the hot air pipe 6 faces the pressure regulating valve 1, and the hot air is discharged into the interior of the hot air pipe 6 through the air outlet pipe 104 and blown out through the hot air pipe 6. The hot air is blown toward the pressure regulating valve 1, which can auxiliary heat the pressure regulating valve 1 and further accelerate the melting speed of the gas in the pressure regulating valve 1.

The gas enters the cleaning cylinder 301 through the air supply pipe 303, and the gas is filtered by the filter plate 302, and impurities in the gas are retained inside the cleaning cylinder 301. The impurity removal effect on the gas is improved by multiple filter plates 302, so that the gas entering the pressure regulating valve 1 is kept clean, further reducing the condensation of the gas, and at the same time improving the combustion efficiency of the gas.

[0029] In order to ensure the filtering effect of the filter plate 302 on the fuel gas, a cylinder changing mechanism is also included. Two cleaning cylinders 301 are provided.

[0030] In order to clean the filter plate 302, a cleaning component is also included. The cleaning component is used to clean the filter plate 302. The cleaning component includes a blowing pipe 501 and a dust collecting bin 502. The fan 201 is connected to the top of the rotating drum 401 through the blowing pipe 501. An air inlet matching the blowing pipe 501 is provided on the cleaning drum 301. The dust collecting bin 502 is connected to the bottom of the rotating drum 401.

When the cleaning drum 301 rotates to the cleaning position, the air inlet and the blowing pipe 501 correspond to each other. The dust removal port and The position of the dust collecting bin 502 corresponds to that of the fan 201, and the fan 201 delivers air to the interior of the cleaning cylinder 301 through the blowing pipe 501. Under the combined action of gravity and wind, the impurities in the cleaning cylinder 301, especially on the surface of the filter plate 302, fall into the dust collecting bin 502 for collection. The dust collecting bin 502 is provided with a plurality of air outlets, through which the air blown by the fan 201 can be discharged to avoid excessive air pressure in the dust collecting bin 502. At the same time, a water-absorbing sponge is arranged inside the dust collecting bin 502. The water-absorbing sponge has water adsorbed inside, which can absorb the impurities blown off, to avoid the impurities in the dust collecting bin 502 from flying and causing secondary pollution in the cleaning cylinder 301.

[0031] In order to improve the cleaning effect of multiple filter plates 302, multiple filter plates 302 are fixedly connected by connecting rods, and the filter plates 302 are movably arranged inside the cleaning cylinder 301. In order to realize the movement of the filter plates 302, a driving component is also included, and the driving component is used to drive the multiple filter plates 302 to move.

After the purging is completed, the magnet 602 enters the interior of the driving bin 601, and the cleaning cylinder 301 blocks the filter plates 302. The magnet 602 and the fixing ring 603 are separated, preparing to subsequently drive and clean the filter plates 302 in another cleaning cylinder 301.

The temperature sensor 7 senses the low temperature environment, turns on the heater 105 and the electric valve 9, and causes the fan 201 to deliver air to the interior of the heating bin 102 through the air supply pipe 8. The air is heated by the heater 105, and the hot air enters the interior of the heating bin 101. The diversion bin 2 and the pressure regulating valve 1 are heated by the heating bin 101 and the heat conducting plate 5.
