る。As a result, it is possible to prevent thermal deterioration of the heat insulating material arranged inside the valve body, and also to prevent the propagation of various bacteria within the heat insulating material.
又このパツキンを利用して弁体と弁座間のシールをも行
うことができるので、部品点数を節減できたり (第1
実施例、第2実施例)、前記シールをより確実に為すこ
とができる(第3実施例)。This seal can also be used to seal between the valve body and the valve seat, reducing the number of parts (see Part 1).
Examples (Second Example), the seal can be more reliably achieved (Third Example).
■ パツキンの基部を中子本体の鍔部と中子カバーの上
端面との間に挟持しているので、パツキンの保持が確実
強固になり、しかもこのパツキンの保持を中子本体と中
子カバーの結合時に同時に行うことができる。■ Since the base of the packing is sandwiched between the flange of the core body and the upper end surface of the core cover, the packing is held securely and firmly. This can be done simultaneously when combining.
■ パツキンの周辺には上向きの環状舌片を設けている
ので、中子の上停止位置において環状舌片はその弾性に
よって弁座に密着し、弁体と弁座との間を確実に密閉す
ることができてシール性の向上を図ることができる。■ An upward-facing annular tongue is provided around the seal, so at the upper stop position of the core, the annular tongue sticks tightly to the valve seat due to its elasticity, ensuring a tight seal between the valve body and the valve seat. This makes it possible to improve sealing performance.
又前記環状舌片は弁座に密着するに際し撓み、弁座と弁
体との間隔設定に寸法誤差がある場合にも、これを吸収
できて設計上有利である。Further, the annular tongue bends when it comes into close contact with the valve seat, and even if there is a dimensional error in setting the distance between the valve seat and the valve body, this can be absorbed, which is advantageous in terms of design.
