CRYOGENNIC LIQUEFIED GAS INTAKE/DISCHARGE VALVE BODY, RECIPROCATING PUMP, AND FUEL GAS SUPPLY DEVICE

摘要

A fluid intake/discharge valve body for suction of a cryogenic liquefied gas fluid into a cylinder liner and discharge of the gas fluid with a piston, includes: a valve seat body including a fluid supply portion to supply the fluid and a fluid exhaust portion; an intake valve biased against the fluid supply portion; and a discharge valve biased against the fluid exhaust portion. The fluid supply portion includes a supply pathway connected to a supply pipe; a dividing wall including intake holes facing the intake valve; and a counterbore recessed portion on the dividing wall to surround the intake holes. The intake valve abuts an edge of the recessed portion when biased against the fluid supply portion. The discharge valve receives fluid pressure from a side of the discharge hole including a recessed portion disposed in a region wider than an outer periphery of the discharge hole.

1. A fluid intake/discharge valve body that is used for suction of a cryogenic liquefied gas fluid into a cylinder liner and a discharge of a cryogenic liquefied gas fluid with a piston, comprising:
a valve seat body, including:
a fluid supply portion configured to supply the fluid, anda fluid exhaust portion configured to exhaust the fluid; an intake valve configured to be biased against the fluid supply portion of the valve seat body; and a discharge valve configured to be biased against the fluid exhaust portion of the valve seat body, the fluid supply portion, including:
a supply pathway configured to connect to a supply pipe,a dividing wall including a plurality of intake holes configured to face the intake valve disposed at an end of the supply pathway, anda counterbore that is a recessed portion disposed on the dividing wall, the counterbore surrounding the plurality of intake holes, and the counterbore configured such that the intake valve abuts an edge of the recessed portion in a case where the intake valve is biased against the fluid supply portion.
