Abstract

A sliding-vane one-way valve and a mud pump thereof comprise a working cylinder which is communicated with a discharge one-way valve and a suction one-way valve respectively. In the discharge one-way valve, a slideable seal match is formed between a sliding sheet of a valve cavity and a valve block seat, and a sealing surface of the sliding sheet is connected with a transmission pin shaft which is located on one side of a through hole of the valve block seat. The transmission pin shaft is connected with a plane slidable rotary driving device of a driving sliding sheet along the plane slidable rotary driving device which is perpendicular to an axis of the valve block seat. According to the sliding-vane one-way valve and the mud pump thereof, a valve core with radial movement is adopted. The direct communication of the one-way valve of the mud pump is achieved. Thick concrete grouts are capable of unhampered passing directly inside a valve body, therefore, the flow resistance of the thick concrete grouts is effectively reduced and the phenomenon that the grouts are prone to clogging in the transporting process is avoided. Due to the fact that a connecting rod or the transmission pin shaft drives the sliding sheet which is used as the valve core to move is connected with the sealing surface of the sliding sheet, the pressure inside the valve cavity strengthens the sealing effect. The sliding-vane one-way valve and the mud pump thereof are suitable for being competent at bad working conditions. The trouble-free service time is long and the volume efficiency of the mud pump is increased.

Description

Sliding vane one-way valve and slurry pump
Technical field
The utility model relates to a kind of one-way valve and adopts the slurry pump of this one-way valve, especially a kind of sliding vane one-way valve and slurry pump that is used for the thick slurry conveying.
Background technique
One-way valve commonly used in the state of the art has non-return valve and one way poppet valve.Its characteristics are following:
(1) non-return valve.
One-way valve is to be used to make medium only to flow along suction port; And the valve that the medium of exhaust port can't reflux; The spool that adopts in the non-return valve is generally steel ball, and non-return valve sealing pair (being sealing surface of seat and ball seal face) is through the motion formation opening and closing of steel ball; In dense thick concrete slurry, adopt non-return valve, the problem that exists in the use is:
1, the steel ball as spool can only move in a limited space, and when non-return valve was opened, dense thick concrete slurry need repeatedly change shape, because the viscosity of fluid, a large amount of kinetic energy are lost.
Frictional force formula according to the working fluid interlayer:
F f=Aμdu/dy
Wherein μ is a viscosity coefficient, and A is the area of contact of liquid layer, the velocity gradient between the du/dy liquid layer.
Concrete coefficient commonly used is 1.3, because the existence of steel ball, dense thick concrete slurry is by layering, and then A increases, and because the existence of viscosity, the velocity gradient between the du/dy liquid layer also increases, and promptly the liquid level skin sharply descends compared to the speed of liquid level internal layer.
Can find out that above formula in the runner of dense thick concrete slurry, baffle being set is that spool can consume a large amount of kinetic energy.
2, for to guarantee that non-return valve has enough apertures; It is the size that its aperture is not less than the valve seat opening; So that non-return valve does not become the bottleneck in the runner; Then the steel ball spool need move enough distances, and the steel ball spool operation be to promote by dense thick concrete slurry, then promote that the steel ball spool opens or close apart from T in the kinetic energy that produces of the range ability of piston cylinder lost.Specifically as shown in Figure 10.As can be seen from the figure; Dense thick concrete slurry is forced the change shape, flow through around the spool, the spool opening and closing apart from T; When the distance of T be provided with too small; Can the dense thick concrete slurry of influence flow, and be provided with excessively when the distance of T, lost for the energy in the running of T in distance.
3, dense thick concrete slurry can't keep its flowability always, and dense over time thick concrete slurry can solidify, thereby stops up non-return valve, makes them can't opening and closing, and whole slurry pump can't be moved.
(2) one way poppet valve.
1, existing one way poppet valve, spool is connected with driving element, and the working surface of spool is generally conical surface, and conical surface cooperates with valve seat, and described driving element is generally oil hydraulic cylinder or pneumatic linear actuator.One way poppet valve exists the kinetic energy rejection identical with non-return valve to reach the problem of easy blocking greatly.
Specifically as shown in Figure 11, the distance of spool opening and closing is T, and the distance of T is provided with too small then dense thick concrete slurry constricted flow, and is excessive then in control system, needs the stand-by period elongated.
2, because need to give the independent outfit driving element of spool; And the piston rod of spool and driving element also moves in dense thick concrete slurry; Then the sealing of driving element also is a problem; The sealing part that is piston rod has increased new source of leaks, and on a slurry pump, has two one way poppet valve at least, and this structure has also limited the lifting of one way poppet valve valve pocket internal pressure.Therefore need the occasion of high-pressure delivery, still adopting non-return valve in the existing technology usually.
