Abstract
The utility model discloses an integrally combined reciprocating pump group valve, which is mainly composed of an upper valve sleeve (4), a lower valve sleeve (10), valve bases (7) which are arranged in the valve sleeves, a ball (6), a travel distance gauge (5), an elastic ring (8), a screw thread press plate (1), a sealing plate (2) and a positioning pin (3) which determines the installation position with a pump head. The travel distance gauge (5) limits the accuracy of the climbing height and the dropping position of the ball (6). The upper and the lower valve sleeves are connected through screw threads, and installation and disassembly are both of the method that the upper and the lower valve sleeves are integrally taken out. The utility model is easy of installation.
Description
The utility model belongs to the suction and the expulsion valve group of the combination brake switch and proporting of the fluid end of reciprocating pump, particularly reciprocating pump.
The suction of prior art and expulsion valve group are partial installation, suck and discharge two valve splits, comparatively simple during assembling, but if will dismantle, the then following suction valve section of maintenance then is difficult for taking out, normally pump case is stood up, the application of force is taken out then, and is very inconvenient for the user.
The purpose of this utility model provides a kind of integral combined reciprocating type pump valve group.That is, suck and the monolithic construction of expulsion valve, be convenient to assembling for combining as a whole with screw thread.Adding the man-hour coaxality easily guarantees.
The purpose of this utility model is to realize like this, last lower valve sleeve is with scyewed joint, and tension, cooperation seam cylinder location by last lower valve sleeve, isolate by an elastic ring between the last lower valve sleeve, to prevent location or damaged screw, lower valve sleeve is by the bottom surface sealing of upper valve sleeve, and upper valve sleeve is sealed by the screw thread pressing plate.Two covers are connected by screw thread centering, and the external diameter concentricity can fully guarantee, is easy to the location, and one is taken out, and is convenient for assembly.
Accompanying drawing is a structure sectional view of the present utility model.In the accompanying drawings, 1: the screw thread pressing plate; 2: sealing plate; 3: locating stud; 4: upper valve sleeve; 5: stroke rule; 6: ball; 7: valve seat; 8: elastic ring; 9: Hua Kongguan; 10: lower valve sleeve; Double dot dash line among the figure is the housing of pump head, is the flange gland above.
Below in conjunction with accompanying drawing, specific embodiment is elaborated, with reference to accompanying drawing, going to the bottom of lower valve sleeve ［ 10 ］ cooperates with the inlet hole of pump head, and assembling valve seat ［ 7 ］ is placed ball ［ 6 ］ in the cover on the valve seat, be stroke rule ［ 5 ］ then, the lifting height of restriction ball ［ 6 ］ and the displacement of left and right directions.Stroke rule have through hole, a colored hole pipe of device ［ 9 ］ on it, Hua Kongguan to press holding position corresponding with plunger hole, flower hole water flowing, and pipe and stroke rule connect elastic ring ［ 8 ］ pad between the going to the bottom of Hua Kongguan ［ 9 ］ and upper valve sleeve ［ 4 ］, with the two isolation, the screw-thread fit of screw thread that lower valve sleeve is suitable for reading and upper valve sleeve end opening, to go up lower valve sleeve and connect tension, the part that is threaded of last lower valve sleeve also has post surface, the inside and outside garden seam of a pair of cooperation location, to last lower valve sleeve centering location, control its coaxiality error.Elastic ring ［ 8 ］ is resiliently deformable under the impaction state that is threaded of last lower valve sleeve, and with Hua Kongguan, stroke rule and valve seat compress.And the upper surface step that is unlikely the following bottom surface that makes upper valve base and lower valve base contacts and produced the location.Component in the upper valve sleeve ［ 4 ］ are identical with lower valve sleeve, it is also identical to assemble and press dress order, position, only be that compressing by screw thread pressing plate ［ 1 ］ and screw-internal thread fit on it of Hua Kongguan ［ 9 ］ compresses, a pad elastic ring ［ 8 ］ between the flower Kong Guanyu screw thread pressing plate, its effect with aforementioned with.Elastic ring promptly prevented the location, the part impact force in the time of can absorbing suction again and discharge medium.Whole valve group is for the locating stud ［ 3 ］ that also is provided with easy to assembly on pump head.After valve was assembled into pump head, pad upper sealing panel ［ 2 ］ formed sealing by flange gland and pump head by Bolt Connection is fastening, and valve group integral body is installed within the pump head.Whole taking-up during dismounting.
The lifting altitude of the inner space restriction ball ［ 6 ］ of stroke rule ［ 5 ］, general ball ［ 6 ］ lifting altitude is in the diameter range of 0.05-2 ball, four gussets of inwall garden Zhou Junbu on stroke rule ［ 5 ］, the garden Zhou Fangxiang of alignment restrictions ball ［ 6 ］ motion makes ball ［ 6 ］ accurately return back to original position in the hole of valve seat ［ 7 ］.One end of stroke rule is an opening, connects with valve seat ［ 7 ］, and the other end is a porose base plate.
Valve seat ［ 7 ］ in the upper valve sleeve ［ 4 ］ is advised ［ 5 ］, Hua Kongguan ［ 9 ］, elastic ring ［ 8 ］ by screw thread pressing plate ［ 1 ］ positioning and fixing by the stroke on it.
Valve seat ［ 7 ］ in the lower valve sleeve ［ 10 ］ is by the rule of the stroke on it ［ 5 ］, Hua Kongguan ［ 9 ］, elastic ring ［ 8 ］, and by the following seat surface location of upper valve sleeve ［ 4 ］, it is fixing to be threaded.
Its advantage is, the integral valve group that last lower valve sleeve is combined as a whole and formed a combination by the screw thread of centre, and coaxality is good, accurate positioning, one piece dismounting, assembling, and the sealing of ball is accurate, and reliable.Be applicable to suction pressure 0-20MP
a, head pressure 5-35MP
aReciprocating pump use.
