Abstract
The invention relates to grouting equipment for grouting grout into a medium such as an underground soil layer, namely a grouting pump for a spherical valve plate. An existing grouting pump adopts a double-valve-ball structure or a double-check-valve structure to suck or discharge the grout; with regard to the double-valve-ball structure, the opening and closing of a valve are realized by own weight of a valve ball or by a spring when the grout is sucked or discharged; the structure is applicable to occasion such as pure cement grout in which the grout contains no particles such as sand; when the grout contains particles such as cement grout, the structure can be blocked by the particles when being opened or closed and cannot be totally closed. At the moment, the double-check-valve structure is competent and is driven by double oil cylinders; a valve core of a check valve is sealed by a rubber sealing part, so complete closing can be realized; but the sealing part at the position is easy to abrade and needs to be replaced frequently, and the use of the grouting pump is affected. According to the grouting pump disclosed by the invention, the spherical valve plate is driven by a single oil cylinder so as to realize grout suction and discharging of the grouting pump; the grouting pump is simple in structure; the rubber sealing part needs not to be replaced frequently; good sealing is realized; the grouting pump is durable in use; use continuity of the grouting pump is guaranteed.
