Abstract
The utility model discloses a check valve for jacking and pouring of concrete. The check valve for jacking and pouring of the concrete comprises a front joint and a rear joint, wherein the front joint and the rear joint are respectively connected with a pump pipe. A front flange is arranged at the rear end of the front joint. A rear flange is arranged at the front end of the rear joint. A moving flashboard is arranged between the front flange and the rear flange. An upper limiting plate which is vertical to the moving flashboard is arranged at the upper end of the moving flashboard. A lower limiting plate which is vertical to the moving flashboard is arranged at the lower end of the moving flashboard. A through hole is formed in the lower portion of the moving flashboard. Baffles are arranged on the two sides of the moving flashboard. The baffles, the front flange and the rear flange are connected through bolts. When the check valve for jacking and pouring of the concrete is used, the check valve is in a sealed state towards the outside, gas does not leak and construction is convenient to perform with safety and reliability. The joints are adopted to be connected with the concrete conveying pump pipe so that the check valve is convenient to use. The check valve can be used repeatedly in a circulation mode and is low in cost.
Description
Technical field
The utility model relates to a kind of flow-stop valve, particularly a kind of flow-stop valve of building for concrete lift-up.
Background technology
At present, the construction technology of steel pipe column inner concrete jacking is: open one than the hole of the bigger 3mm of carrier pipe at the bottom of steel pipe column tube wall, be attached thereto with the outlet of high-pressure delivery pump line with concrete pump, concrete is injected in the steel pipe column by carrier pipe continuously by pump pressure, fills with concrete in pipe.The steel pipe column top arranges the overflow steam vent, to reduce pumping pressure.On the pump line of steel pipe column bottom, adopt the method that flow-stop valve is set, prevent that concrete from flowing backwards.At present, adopt more flow-stop valve to adopt the board plug type structure, plug in flashboard is wedge shape, and adopts finger setting.Under the effect of pumping of concrete, the pump line vibrations, and the vibrations of pump line can directly cause the loosening of wedge shape flashboard, thus making flow-stop valve gas leakage, safety and reliability are lower.
The utility model content
The utility model for solve the technical problem that exists in the known technology provide a kind of safety and reliability higher be used for the flow-stop valve that concrete lift-up is built.
The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: a kind of flow-stop valve of building for concrete lift-up, comprise the front connector and the back joint that are connected with pump line respectively, the rear end of described front connector is provided with forward flange, the front end of described back joint is provided with rear flange, between described forward flange and described rear flange, be provided with movable flashboard, the upper end of described movable flashboard is provided with perpendicular upper limit plate, the lower end of described movable flashboard is provided with perpendicular lower limiting board, the bottom of described movable flashboard is provided with via, both sides at described movable flashboard are equipped with baffle plate, described baffle plate, described forward flange is connected by bolt with described rear flange.
Rear end face at described forward flange is equipped with the front sealing packing ring, at the front end face of described rear flange the rear seal packing ring is installed.
Described via is diminishing horn-like along the concrete throughput direction.
Advantage and the good effect that the utlity model has are: when 1) using, externally be closed state, and air tight, easy construction, safe and reliable; 2) adopt joint to be connected with concrete delivery pump pipe, easy to use.3) can repetitive cycling use, cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the 1-1 sectional drawing of Fig. 1.
Among the figure: 1, pump line; 2, front connector; 3, forward flange; 4, movable flashboard; 4-1, lower limiting board; 4-2, via; 4-3, upper limit plate; 5, rear flange; 6, bolt; 7, back joint, 8, baffle plate.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of flow-stop valve of building for concrete lift-up, comprise the front connector 2 and the back joint 7 that are connected with pump line 1 respectively, the rear end of described front connector 2 is provided with forward flange 3, the front end of described back joint 7 is provided with rear flange 5, between described forward flange 3 and described rear flange 5, be provided with movable flashboard 4, the upper end of described movable flashboard 4 is provided with perpendicular upper limit plate 4-3, the lower end of described movable flashboard 4 is provided with perpendicular lower limiting board 4-1, the bottom of described movable flashboard 4 is provided with via 4-2, be equipped with baffle plate 8 in the both sides of described movable flashboard 4, described baffle plate 8, described forward flange 3 is connected by bolt 6 with described rear flange 5.During use, in the flashboard seam of described forward flange 3 and described rear flange 5 and 4 formation of described movable flashboard, fill butter, to prevent flashboard seam gas leakage in the process that the concrete pumping jacking is built.Also can solve the problem of flashboard seam gas leakage from structure: the rear end face at described forward flange 3 is installed the front sealing packing ring, at the front end face of described rear flange 5 the rear seal packing ring is installed.No matter be in the flashboard seam, to fill butter or at the end face of flange seal washer is installed, all be for when flow-stop valve uses, externally be closed state.Described via 4-2 is diminishing horn-like along the concrete throughput direction.To reduce concrete transporting resistance.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
