Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas valve seats, in particular to a shock-resistant valve seat for gas. Background Art
[0002] The gas valve seat is an important part of the gas valve. It cooperates with the valve core to control and regulate the flow of gas. The gas valve seat usually has good sealing performance to prevent gas leakage, thereby ensuring the safe operation of the gas system. In order to prevent gas leakage or equipment damage caused by vibration during an earthquake, thereby causing safety hazards, the utility model proposes a seismic-resistant valve seat for gas.
[0003] According to the search, the Chinese patent document, announcement number: CN220037837U, discloses a shock-absorbing tool and system for a gas pressure reducing valve, which detachably connects the inlet pipe and the outlet pipe to the inner side wall of the first elastic shock-absorbing pad and the inner side wall of the second elastic shock-absorbing pad respectively. When the gas pressure reducing valve vibrates severely, the first elastic shock-absorbing pad and the second elastic shock-absorbing pad will respectively apply forces opposite to the vibration direction to the inlet pipe and the outlet pipe of the gas pressure reducing valve, thereby reducing the vibration amplitude of the gas pressure reducing valve. However, in actual use, the device can only perform shock-absorbing treatment on the gas valve and the inlet and outlet pipes, and cannot automatically close the valve when an earthquake occurs, so it may still cause gas leakage, etc., causing certain safety hazards.
