    摘要： The invention relates to a device for installing piping in process plants in the food and beverage industry, wherein each valve bank opens directly into the lower tank floor of an associated tank of the process plant or/and each valve bank is connected by means of a pipe connection to an associated process aggregate or tank of the process plant and the pipe connection opens into the end of the valve bank on the tank or process side. The second closing member is designed as a hollow bar and the second seat seal is received in an end face of the hollow bar-shaped second closing member facing the first closing member. The hollow bar-shaped second closing member comprises a cylindrical receptacle hole on the inside in the end segment thereof receiving the second seat seal, said hole having the same diameter as the cylindrical first seating surface, and the receptacle hole and the first seating surface have a flush transition in the closed position of the second closing member.

    摘要： The invention relates to a seat cleaning-capable double-seat valve (1), comprising two closing members (3, 4) that are arranged in series, can be moved relative to one another and are configured as sliding plungers, which in the closed position of the double-seat valve (1) prevent the overflow of fluids from one valve housing part (1 a; 1 b) to another (1 b, 1 a) by way of a connecting opening (2c) joining the valve housing parts (1 a, 1 b) and which delimit a leakage cavity (9) both in the closed and open positions, said cavity being connected to the vicinity of the double-seat valve (1) by way of a tubular shaft (4b/4c) that is integrally formed on the lower second closing member (4), relative to a vertical normal position of the double-seat valve (1), a discharge bore (4d) being arranged in said shaft. The second, dependently driven closing member (4) is configured bigger than the first independently driven closing member (3), so that accordingly the double-seat valve (1) opens downward and drainage of the leakage cavity (9) likewise takes place downward.

    摘要： The invention relates to a device (100) for driving a double seat valve (1) having two closing members (3, 4) disposed in series and displaceable relative to each other and preventing, in the closed position of the double seat valve (1), the flow of fluids from a valve housing part (1 a; 1 b) into another (1 b; 1 a) through a connecting opening connecting said valve housing parts of a valve housing (10) with each other, and, even in the open position, bounding a leakage cavity (9) of the double seat valve (1) connected to the vicinity of the double seat valve (1).

    摘要： The invention relates to a double-seat valve, the seats of which can be cleaned and which is improved with respect to the prior art in such a way that the seat-cleaning flow can be directed into and out of the hollow leakage space with as few eddies as possible while the seat areas are securely protected against direct increasing pressurization. In order to do so, among other things, the double-seat valve (1) is fitted with closing members (3, 4) which can be independently moved into a seat-cleaning position by being partly lifted to form a gap in order to rinse the coaxial seat surfaces (2a, 2b) thereof. The second closing member (4) is brought into the seat-cleaning position thereof by means of a second partial lift (T2) in the same direction as the opening movement, while the first closing member (3) is brought into the seat-cleaning position thereof by means of a first partial lift (T1) in the direction opposite the opening direction. Furthermore, in the closed position, a stop surface (4T) of the second closing member (4) rests on the second seat surface (2b), immediately adjacent to first seat surface (2a), said stop surface (4T) forming a second circumferential edge (U2) along with the peripheral wall (4c; 4h). In addition, the peripheral wall (4c) turns into a rotationally symmetrical deflection surface (4d) (starting point of a contour (K)) at the end thereof facing away from the first closing member (3), and said deflection surface (4d) extends into a face (4e) of the cavity (4b) (final point of the contour (K)), said face (4e) of the cavity (4b) running substantially perpendicular to the longitudinal axis of the second closing member (4). Moreover, the contour (K) of the deflection surface (4d) has no sharp bends from a meridian cross-sectional view. And finally, a directional vector in the final point of the deflection surface (4d) points to a concentric discharge bore (3d; 3d*) located in the first closing member (3) without colliding with the closing member (3) and generating banking-up pressure in the area of the zones thereof which border the hollow leakage space (5).

    摘要： The invention relates to a double seat which is capable of cleaning the seat and which is improved compared to that of the prior art, whereby a delivery as free from turbulence as possible of the seat cleaning flow into and out of the leakage cavity is ensured, and a pressure-increasing direct action upon the seat areas is reliably prevented. This is achieved in that: the second closing element (4), when in its closed position rests with a stopping surface (4e), arranged on the boundary surface thereof radially adjacent on the inner side to the second seal (7), on the second seating surface (2b) and directly adjacent to the first seating surface (2a, 2g) with a central recess (4d) provided in the front face of the second closing body (4) facing the leakage cavity (5), beginning on the radial outside with a rotationally symmetrical deflector surface (4b) (starting point for the contour (K)) and frontwardly defined on the front face (4c) oriented essentially perpendicular to the longitudinal axis of the second closing body (4) wherein the deflector surface (4b) opens in the front face (4c) (opening point of the contour (K)), the deflector surface (4b) and the stop surface (4e) form a second circumferential edge (U2) directly adjacent to a first end section (2g) f the first seat surface (2a) in the closed position of second closing body (4), viewed in meridional section the deflector surface (4b) has a contour (K) with a bend-free curve, a directional vector in the opening point of the deflector surface (4b) faces a drain drilling (3d) arranged centrally in th first closing body (3), without coming into contact with the first closing body (3) in the vicinity of the regions thereof around the leakage cavity (5) or with the middle seal (8; 8*) such as to form a back pressure and a front face boundary of the first closing body (3) facing the leakage cavity (5) has an axial security separation (x) form the directional vector to a outlet point on the second seating surface (2b) in the first end section (2g) designed as a first deflector edge (U1).
