Embodiment Construction

[0026] The present invention will be further described below in conjunction with the drawings and embodiments.

[0027] Such as Figure 1-14 Shown.

[0028] A dual gas source selector valve with cut-off and closing function, comprising a valve body 1. The valve body 1 is provided with a high calorific value air inlet 2, a low calorific value air inlet 3, and a control valve connected to the air inlet The main air outlet 6, the main air inlet 4 connected to the main air outlet of the control valve, and the ODS air inlet 5 connected to the ODS outlet of the control valve. The valve cavity 9 of the valve body 1 is provided with a high heating value Gas intake bin 10, low-calorific value gas intake bin 11 and ODS gas chamber 22, such as figure 1 Shown. The main air outlet 6 communicates with the valve cavity 9, the ODS air inlet 5 communicates with the ODS air chamber 22, and the main air inlet 4 communicates with the air inlet of the dual air source nozzle 18 with high heating value...

Abstract

The invention relates to a double gas source selection valve with stopping function, which comprises a valve body (1) and is characterized in that a valve cavity (9) of the valve body (1) is provided with a high heating valve gas inlet bin (10) and a low heating valve gas inlet bin (11), the high heating valve gas inlet bin (10) and the low heating valve gas inlet bin (11) are provided with gas outlets communicated with the valve cavity (9) and are internally respectively provided with a sealing washer (12) capable of plugging the corresponding gas outlet, the two sealing washers (12) are simultaneously fixed on a drive rod, one passed end of the drive rod is connected with a drive lever, the drive lever is supported against a knob rod, and a drive groove is arranged on the knob lever. The invention has the advantages of simple structure, small size, no gas source output in stopping, safety and reliability.

Description

Technical field [0001] The invention relates to a gas appliance, in particular to a gas appliance that can be used for both high calorific value gas (such as liquefied gas) and low calorific value gas (such as natural gas and biogas, etc.), specifically a dual gas source gas appliance The dual gas source selection valve with cut-off function is used. Background technique [0002] At present, with the continuous progress of transportation technology and the increasing shortage of oil resources, low-calorific value gas such as natural gas and biogas has gradually entered people’s daily lives. Urban single energy is gradually being broken by the multi-energy supply system, in the same household. At the same time, it has become possible to connect gas supply pipelines for coal gas, natural gas, liquefied gas, biogas and other energy sources. People can choose suitable gas to use according to market price changes and gas supply conditions. Take gas heaters as an example. In the past,...
