Definitions

  • the invention relates to a flushing valve for whirling up sedimentation and for breaking up and mixing in substances that form floating covers in pumping stations, in particular
  • valve closing position sits in front of a sealing seat mounted on the outlet side in the valve housing.
  • valve 35 is added without hindering the flow through the valve.
  • a vacuum is generated by the flow of the pump medium in the valve body, which affects the membrane and causes the valve to close after a certain time.
  • the membrane is moved upwards by the negative pressure generated and thus also moves the valve body.
  • the speed of the movement of the diaphragm in the direction of the valve housing is regulated in that the valve head has an opening which allows the flow of a damping medium which is contained in the bellows into the space between the valve head and the diaphragm.
  • the size of the opening and the level of the negative pressure directly determine the speed. Oil is usually used as the damping medium.
  • the speed is also influenced by the viscosity of the damping medium and is therefore strongly temperature-dependent.
  • the setting of the flushing time to different liquid temperatures must therefore be carried out with a regulating valve attached to the flushing valve and is therefore not readily variable for the operator of the pumping station.
  • this flush valve takes up a lot of space, in particular due to the attached bellows, and has a relatively high weight.
  • the invention is therefore based on the object of developing a new flushing valve whose flushing time is not temperature-dependent, ie. That is, that no readjustments to the valve have to be carried out at different temperatures, the flushing time of which can also be adjusted as required from case to case and that, moreover, it can be produced with relatively small dimensions and light weight.
  • this object is achieved with a flushing valve, which is characterized in that a device acting in this for locking the valve body is arranged in its rest position on the valve cup and that after actuation of the locking device The valve body can be conveyed from the pump medium flowing past it to the rest position in the valve cup against the seal.
  • the flushing valve according to the invention thus shows no dependency with regard to the flushing time on the liquid temperature prevailing in the pump station.
  • the flushing time outside of the pumping station can be set as desired by the operator from case to case, without having to make any adjustments to the valve body itself.
  • the entire flushing valve is reduced in weight and volume.
  • a working cylinder with a piston rod is provided as the locking device and the piston rod is slidably arranged in front of the valve body through an opening in the valve cup, the piston rod locking the valve body in the extended position and releasing it in the retracted position.
  • the piston rod locking the valve body in the extended position and releasing it in the retracted position.
  • no parts of the locking device extend into the valve cup.
  • B. a permanent magnet slidably arranged in a working cylinder, which locks a magnetic valve body in the extended position. By retracting the permanent magnet, the magnetic force exerted on the valve body is reduced to such an extent that it is released.
  • the opening is expediently arranged on the side of the venti cup facing the outlet.
  • the working cylinder is actuated pneumatically or hydraulically or electromagnetically.
  • an embodiment is also conceivable in which the working cylinder is actuated purely mechanically.
  • the valve housing typically has the shape of a cylinder and a ball is provided as the valve body.
  • the valve body has a higher density than the medium to be conveyed and the valve cup points downward after the valve has been installed in the pump station.
  • the valve body is then carried upwards by the flow of the pump medium and brought in front of the sealing seat.
  • valve body has a lower density than the medium to be pumped and the valve cup points upwards after the valve has been installed in the pump station.
  • the valve body is then brought down over the delivery flow of the pump in front of the sealing seat.
  • Such a flushing valve can be installed at the outlet of the pump or on the pump line.
  • the inlet cross-section is smaller than the outlet cross-section in order to create a vacuum which favors the actuation of the ball.
  • Venti 1 is a flushing valve with Venti 1 body lying at the bottom
  • Fig. 2 shows a flushing valve with the valve body at the top
  • the flush valve 1 consists of a Venti 1 housing 2 with an inlet 3 and an outlet 4, the inlet cross-section 14 being smaller than the outlet cross-section 15, in order to create a negative pressure when conveying in the Venti1 housing 2 achieve.
  • the inlet 3 is connected to the pressure side of the pump.
  • a valve cup 5 is attached to the valve housing 2.
  • This ball 6 rests in the valve opening position I in the valve cup 5.
  • the ball 6 In the valve closing position II, the ball 6 is located in front of a sealing seat in front of the outlet 4 in the valve housing 2 7.
  • valves 1 shown are attached to the pressure line 12.
  • the valve 1 has an eyelet 13.
  • the valve cup 5 has an opening 8 which is arranged on the outlet side.
  • a piston rod 10 projects into this through this opening 8
  • the piston rod 10 is pressed out of the pneumatic cylinder 9.
  • the pump pressure passes through the flushing line and the outlet 4 because of the ball 6 held downwards. The operator can keep this flushing position set at his own discretion.
  • the extended piston rod 10 is pressed back into the pneumatic cylinder 9. The piston rod 10 thus clears the way for the ball 6.
  • the pump medium flowing past the ball 6 tears the ball 6 in front of the sealing seat 7 and thus ends the flushing.
  • the ball 6 is heavier than the pump medium to be pumped and is consequently located in the flushing valve 1 below.
  • FIG. 2 shows a flushing valve in which the ball 6 is lighter than the pumping medium to be conveyed and thus floats in the flushing valve.
  • the contact pressure of the ball 6 on the sealing seat 7 is released by the pressure equalization of the pump medium between inlet 3 and outlet 4.
  • the ball 6 then floats in the pump medium or sinks down into it until it is received by the valve cup 5 and can be locked again by means of the piston rod 10.

Abstract

L'invention concerne un robinet de vidange pour soulever en tourbillons des sédiments et pour rompre et mélanger des substances d'eaux usées formant des chapeaux d'écume dans des stations de pompage d'eaux usées. Ce robinet de vidange comporte une cage (2) avec une sortie (4) et une entrée (3) reliée au côté refoulement de la pompe, une coupelle (5) appliquée hermétiquement contre la cage (2), et un corps de robinet (6) qui se trouve dans la coupelle (5) lorsque le robinet est en position d'ouverture (I), et qui repose en amont d'un siège étanche (7) monté côté sortie dans la cage (2), lorsque le robinet est en position de fermeture (II). Un dispositif agissant dans la coupelle (5) bloque le corps de robinet (6) dans sa position de repos. Après actionnement du dispositif de blocage, le corps de robinet (6), lequel est avantageusement un flotteur sphérique, est transporté, depuis sa position de repos dans la coupelle, contre le siège étanche par le milieu de pompage en écoulement. Dans un mode préféré de réalisation, le dispositif de blocage est constitué d'un vérin d'actionnement (9) doté d'une tige de piston (10) à commande pneumatique, qui est poussée dans la coupelle (5) par l'intermédiaire d'une ouverture.
