b. 従来の技術 周知のように流体の流れを制限あるいは制御する手段と
して各種のバルブが用いられている。b. Conventional Technology As is well known, various valves are used as means for restricting or controlling the flow of fluid.

Valve spring 103 that presses 2 toward the valve seat 100 side
It consists of and.

02とバルブシート100との間に流体に含まれている固形
物等が挾まることがある。Since the plunger pump is sometimes used for pumping cement clinker, for example, in the conventional valve device, the valve body 1 is opened / closed as the valve body 102 is opened / closed.
Solid matter or the like contained in the fluid may be caught between 02 and the valve seat 100.

時点でバルブ装置の交換を余儀なくされ、作業の中断を
招いていた。Since the valve seat 100 used in the conventional valve device is a tubular body, solids can easily pass through it. Moreover, since the valve seat 100 and the valve body 102 are made of metal, the space between the valve seat 100 and the valve body 102 is small. If a solid substance or the like is caught in the valve device, the opening / closing operation of the valve device may not be reliably performed. For this reason, it becomes impossible to pump a fixed amount of fluid at fixed intervals, resulting in a decrease in work efficiency associated with the use of the pump. In addition, there is a drawback that the valve seat 100 or the valve body 102 is scratched by the solid matter that is sandwiched between the valve seat 100 and the valve body 102, and the fluid leaks from the gap. Therefore, in the past, the valve device had to be replaced at that time, resulting in interruption of the work.
そこで、流体中の固形物の流入を防止し、かつ耐久性の
向上を図ることができるバルブ装置を発明した（特願昭
62−237996号）。Therefore, we have invented a valve device that can prevent the inflow of solid matter in the fluid and improve the durability (Japanese Patent Application No.
62-237996).

代えて木製とすることもある。This valve device corresponds to a valve seat 107 in which a valve seat portion 104 is formed in a concave shape corresponding to a substantially spherical surface and a predetermined number of fluid passages 105 opening in the concave surface 105 are formed, and a concave shape of the valve seat 107. A valve cover 110 and a spring retainer 111 for holding the valve body 108 on the concave surface 105 of the valve seat 107 via a valve spring 109. At least one of the main bodies 108 is molded or covered with a hard elastic material, or one is molded with a hard elastic material and the other is covered with a hard elastic material. Further, the hard elastic material may be replaced with wood.

があってもバルブの開閉に支障を来たすことはない。According to this valve device, since the fluid passage 106 formed in the valve seat 107 is thin, it is difficult for solid matter to pass through. If the valve seat 107 and the valve body 10 are passed through the fluid passage 106,
Even if a solid material is caught between the valve seat 107 and / or the valve body 108, the valve seat 107 and / or the valve main body 108 has elasticity, so that the solid material does not interfere with the opening / closing of the valve.
