The present invention relates to a fluid-blocking double-seated valve in which a leak detection space with a circular contour can be acted upon by a cleaning liquid.

また、外縁においては構造上複数の狭い間隙を持
つ空間の形状が極めて複雑になり、これらの間隙
は不十分な洗浄によりきれいにならない。 Cleaning of the leakage detection space of the double-seat valve is necessary, since fluid generally flows through the leakage detection space for a short time after each switching process. The same thing is done in case of damage to the sealing device. Now, for hygiene reasons, it is necessary to clean this space regularly at short time intervals.
For this reason, existing structures of this type consider introducing the cleaning liquid into the leakage detection space both from above and from below. However, in both cases, the supply takes place in the center of the leakage detection space, which has a circular contour. The cleaning liquid is led out from the center, from where it has to flow back, back into the center again, and then generally flows downwards. As a result of the introduction into the center and the deflection outwards, the velocity is reduced due to cross-sectional enlargement towards the outer edges. At the external reversal point the velocity is zero. Since the cleaning action of such cleaning fluids is primarily determined by the flow rate, these known devices provide an insufficient cleaning effect. Furthermore, at the outer edge, the shape of the space is quite complex with several narrow gaps due to the structure, and these gaps cannot be cleaned due to insufficient cleaning.

This problem is solved in that the cleaning liquid is supplied to the leakage detection space tangentially to the contour of the leakage detection space.
本発明の別の特徴によれば、洗浄液の供給管路
が弁座を貫通している。 According to another characteristic of the invention, the supply line for the cleaning liquid passes through the valve seat.

Removes dirt that enters the interior from the outside.
本発明による、流体を遮断する両座弁の実施例
を図面により以下に説細に説明する。 Embodiments of a double-seated valve for shutting off fluid according to the invention will be explained in detail below with reference to the drawings.

設けられている。 Reference numeral 1 designates a closure member having both valve heads 2,3. The valve head 2 closer to the fluid inflow side Z terminates in a valve stem 2a, via which the valve closing member 1 can be opened and closed by appropriately moving the valve stem 2a upwards or downwards. It is done. The connection between the upper valve head 2 and the lower valve head 3 is via a protrusion 2b, around which a number of holes 3a are provided which open into the hollow cylindrical extension 3b of the lower valve head 3. It is being

て外へ流出する。 A leakage detection space 9 is provided between the two valve heads 2 and 3, and this leakage detection space is communicated with the atmosphere via the hole 3a of the lower valve head 3 and the hollow cylindrical extension 3b. Therefore, if the upper valve head 2 does not abut hermetically against its valve seat surface 6 in the closed position shown in FIG. It flows out through 3b.
特に第２図に明示されているように、漏洩検出
空間９の輪郭は円形である。 As is particularly clear in FIG. 2, the contour of the leakage detection space 9 is circular.

This supply line 10 passes through a valve seat 8 that is common to both valve heads 2 and 3, and is provided so that the cleaning liquid R is supplied to the leakage detection space 9 in a direction tangential to the contour of this leakage detection space. ing. By supplying the cleaning liquid R tangentially in this manner, a very large cleaning effect is obtained, and this cleaning effect extends to places that are difficult to reach. The dirty cleaning liquid is then drained out via the hole 3a and the hollow cylindrical extension 3b.
