本発明は、粉塵等を多量に含んだ流体、とくに高温の粗
コークス炉ガスを流通及び遮断するための開閉弁に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an on-off valve for circulating and shutting off fluid containing a large amount of dust, particularly high-temperature crude coke oven gas.
従来、粉血等が多量に含まれている流体を遮゛断・する
”ためめ開閉弁として、金属製のシートリングを角いた
ボール弁が数多く使用され゛ている。Conventionally, many ball valves with square metal seat rings have been used as on-off valves for shutting off fluids containing a large amount of powdered blood, etc.
この弁はシール性が良好であるが、大口径のも□゛のは
構造上大重量となり、経済的に不゛利であ′る。Although this valve has good sealing performance, the larger diameter valve is structurally heavy and economically disadvantageous.
蓋た別の構造の開閉弁として玉形弁やアングル弁がある
が、これらは流路が曲っている゛ため、弁箱内に粉塵゛
が付□着しやすく、その作動に支障をきたすおそれ゛が
゛ある。しかも弁箱内のシー□ト直に１粉塵が゛付着し
、シール性が低下しセしまうなどの間題がある。Globe valves and angle valves are open/close valves that have a different structure with a lid, but because these have curved flow paths, it is easy for dust to accumulate inside the valve box, which may interfere with its operation. There is. Moreover, there are problems such as dust adhering directly to the seat inside the valve box, which deteriorates the sealing performance.

〔実施例〕
以下本発明を図示する実施例を参照して説明する。゛ The present invention provides a linear flow path for fluid. 1 valve body and a flat plate having a through hole having the same shape and size as the flow passage cross section of the valve body, and a flow passage opening/closing valve interposed between the two valve bodies so as to be movable in a direction transverse to the flow passage. a pair of sealing seat rings interposed between the valve body and both valve bodies; and a pair of sealing seat rings attached to the fluid inflow side valve body to press the seat rings toward the fluid outflow side valve body. Embodiments The present invention will be described below with reference to illustrative embodiments. .

４は。The valve bodies J and j have a straight cylindrical shape and form a straight fluid flow path therein. However, both valve bodies 1.2 are not in direct contact with each other, but are assembled via seat rings 3, 4, a valve body 5, and an elastic body 6, which will be described later. Both valve bodies J, j
The valve body 5 interposed therebetween is made of a substantially rectangular flat plate, as shown in FIG. 2, and has a through hole 7 formed in its lower part. This through hole 7 has the same shape and dimensions as the cross section of the flow path formed between the valve body 1.2. This valve body I has an operating rod 8 attached to its upper end.
By operating the handle 9 screwed together with the valve body 5
It is designed to rise or fall. Figure 1 shows the state in which the valve body 5 is raised, and the flow path is opened by the through hole 7. Further, although not shown, when the valve body 5 is lowered, it gets caught in the flat plate portion of the valve body 5 and closes the flow path. Seat rings 3 and 4 are interposed on both sides of the valve body 5. Each seat ring3.

を保持してりる。Each is made of metal and maintains sealing properties at the contact portion between the valve body 5 and the valve bodies 1 and 2. An elastic body 6 is attached to the seat ring 3 provided on the fluid inflow side. This elastic body 6 is fixed to the fluid inflow side valve body l by a method that ensures airtightness, for example by welding the entire circumference, the other end is fixed to the seat ring 3 in the same way, and the whole is curved outward. The seat ring 3 is pressed in the direction of the valve body 5 by elastic force. Therefore, the elastic pressing force of the elastic body 60 maintains the sealing performance between the seat ring 3.4 and the valve body 1.

In the figure, reference numeral 14 denotes a support member that prevents the elastic body 6 and the seat ring 3 from shifting.

。As explained above, in the on-off valve according to the present invention, the fluid flow path is straight, and even when the flow path is open, the seat is in contact with the valve body. Therefore, the seat surface does not come into contact with dust. Therefore, there is no adverse effect from dust and good sealing performance can be obtained.Furthermore, the on-off valve of this invention is very compact and economical compared to a ball valve when it has a large diameter. In the case of high-temperature fluids such as gases, the material of the seat ring, elastic body, etc. can be sufficiently handled by using heat-resistant materials such as stainless steel.
