Definitions
- the invention relates to a valve arrangement, in particular for use as Check valve or suction or pressure side valve one Positive displacement pump, with circular disk-shaped closing body and associated, annular valve seat.
- the suction and pressure valves of positive displacement pumps are very common plate-shaped closing body, which in the closed state of the valve with annular flat surfaces on associated annular surfaces of the plane resting respective annular valve seat.
- the plate-shaped closing body by valve springs in the closed position urged, the valve springs typically as helical compression springs formed and on the side remote from the valve seat side of the respective Closing body are arranged.
- valve arrangements can be used as standard valves of pumps be considered.
- the closing bodies and valve seats represent wear parts of a pump, which have to be replaced from time to time. However, that is Life of the closing body and valve seats of a strong dispersion subjected. On the one hand is under optimal conditions with one to expect gradual wear. On the other hand, through Dirt in the pumping medium a sudden leak of the Valves are caused. For example, if between valve seat and Locking body sandwiched a grain of sand or the like and in the subsequent opening phase of the valve is not immediately flushed away, are damage to each other sealingly cooperating Surfaces of closing body and valve seat inevitable. In addition, occurs in Pressure stroke of the displacer of the pump between closing body and Valve seat in the area of the grain of sand strong cavitation due to the valve can not close correctly. This cavitation leads to a short time further damage.
- the object of the invention is therefore to provide a valve assembly in which Wear damage to the closing bodies and valve seats with very little effort and often without spare parts inventory eliminate to let.
- the invention is based on the general idea, closing body and Valve seat of a valve turnable form, so that when worn the cooperating sealing surfaces of closing body and Valve seat, the two parts only expanded and turned and again must be installed.
- Each of these two parts has one "Reserveseite” with it if necessary with the other part can interact.
- a suction and pressure valve combination in particular a pump, for the suction and the pressure valve identical closing body and to provide valve seats.
- suction and pressure valve same closing body and may have the same valve seats, at a disassembly and subsequent assembly of the valves readily a closing body and / or a valve seat between suction and pressure valve to be reversed. A wrong assembly is excluded.
- a disposal Leakage of a valve is just to make sure that the Closing body and the valve seats after assembly with unworn Cooperating sealing surfaces with each other.
- suction and pressure valve also have the same Valve springs, so that even here by interchanging the springs no Incorrect assembly can occur.
- Fig. 1 is a sectional view of a valve body of a pump and a pump adjoining pump cylinder with movable plunger and
- FIG. 2 is a comparison with FIG. 1 enlarged sectional view of the Valve housing body arranged suction and pressure valve assemblies.
- a positive displacement pump has at least one cylinder 100 and a plunger 101 slidable therein, in a conventional manner is drivingly connected to a crank mechanism, not shown, i. Rotational movements of a crankshaft of the crank mechanism are in translational strokes of the plunger 101 implemented.
- pumps have three cylinders 100 in series and accordingly, three plungers 101.
- Valve housing body 1 At one end of the cylinder 100 and the cylinder 100 is a Valve housing body 1 is arranged, which by screws 6 and Nuts 7 with the cylinder 100 and the cylinders 100 or Crank engine is connected.
- valve body 1 Within the valve body 1 is perpendicular to the plane of the drawing a connected to a suction line, not shown Saugsammelkanal 102 and in parallel with one also not illustrated pressure line connected pressure collection channel 103rd arranged.
- the suction collecting channel 102 is connected to the Pressure collecting channel 103 through a valve assembly 104th receiving valve channel connected, which in turn via a Transverse bore 105 with the interior of the respective cylinder 100th communicated.
- valve channels 102 In extension of the valve channels 102 may at suction collection Closing screws 9 may be arranged with sealing rings 10, so that the respective valve channel is accessible via the suction manifold 102.
- Each valve assembly 104 is in the associated valve channel between a Ring stage near the Saugsammelkanals 102 and a pressure piece. 2 held, which in turn by means of a flange 5, the am Valve housing body 1 is fastened by means of stud bolts 3 and nuts 4, is stretched against the facing end face of the valve assembly 104.
- seals 13 are arranged, which are the Annular gaps between the outer circumference of the valve assembly 104 and the Seal the valve channel in the valve body 1.
- One in the drawing lower seal 13 is seated between the suction collection channel 102 and the the interior of the cylinder 100 communicating area of the Valve channel.
- a mean in the drawing seal 13 is between this latter area and the pressure collecting channel 103 arranged.
- An upper seal 13 in the drawing seals the Pressure collecting duct 103 to the outside.
- valve arrangement 104 comprises a between the suction collection channel 102 and the interior of the Cylinder 100 effective suction valve as well as between the interior the cylinder 100 and the pressure collecting channel 103 effective pressure valve.
- the suction valve is essentially by a lower Part of Fig. 2 illustrated annular valve seat 11 and a so cooperating plate-shaped closing body 12 is formed, which by a helical compression spring 14 against the aforementioned seat 11th is tense.
- a helical compression spring 14 against the aforementioned seat 11th is tense.
- another valve seat 11, another plate-shaped closing body 12, and another closing spring 14 is provided, wherein valve seat, Closing body and valve spring for suction and pressure valve are identical.
- valve seats 11 and the closing bodies 12 are each symmetric to a radial center plane, i. the two of each other opposite end faces of each closing body 12 and the other facing away from each end of each valve seat 11 are identical. These parts can thus each interchanging the top and bottom or from Upper and lower ends are mounted.
- valve seats 11 and one of the closing body 12 by wear or Pollution unusable, these parts can be removed and subsequently turned over and reinstalled so that the respective closing body 12 and the respective valve seat 11 with Wear-free sealing surfaces can interact.
- the closing body 12 are each with annular Planar surfaces on plan annular end faces of the valve seats 11.
- the closing bodies 12 and the valve seats 11 other cooperating sealing surfaces provided.
- the border areas of the upper and Bottoms of the closing body 12 have the shape of spherical caps, when the cooperating annular sealing surfaces of the Valve seats 11 cone-shaped, i. according to the inside of the Lateral surface of a truncated cone, are formed, wherein the Truncated cone must be so shaped and dimensioned that the Kugelkalotten printing can rest tangentially on a ring line.
- each closing body 12 On the top and bottom of each closing body 12 is an annular step molded, which serves to center the respective closing spring 14.
- an annular web is provided which each axially between one of the seals 13 and one substantially Cylinder-like intermediate piece 15 or 16 is arranged, which as Abutment for the respective valve spring 14 is formed and with Cross holes is provided over which the interior of the respective Intermediate piece 15 or 16 with the interior of the cylinder 100 or the pressure manifold 103 communicates.
- a ring stage is formed in each case, which serves as an abutment for the respective valve spring 14 is used.
- the intermediate piece 16 has the ring step in Compared to the intermediate piece 15 a smaller distance from adjacent valve seat 11, so that the valve spring 14 of the pressure valve has a correspondingly increased bias.
