Abstract

The utility model relates to a cast iron frame steel gate which belongs to the technological field of a hydraulic gate. The technical problem to be solved is to provide an economic and durable, non-pollution and corrosion resistant cast iron frame steel gate with good water stopping effect of gate and frame mating surface. The technical points are: a gate slot (1) adopts a cast iron gate frame or inlays a cast iron or a copper bar (4) on the gate frame; an oblique wedge iron (5) is arranged on a steel gate body (2), which is matched with an eccentric stopping pin or a pressing plate (3) arranged on the gate frame. The gate slot adopts the cast iron gate frame or inlays the cast iron or the copper bar on the gate frame, as a result, the production cost is reduced and an ideal water stop effect is achieved. The gate body adopts a steel gate, which ensures the gate body to bear a high water pressure, and reduces the resistance in opening and closing processes. The coordinate application of the oblique wedge iron and the eccentric stopping pin or the pressing plate ensures that the gate body attaches to the gate frame. The mating surface water stopping is adopted, therefore, the longer the time is, the smoother the mating surface is and the better the water stopping effect is.

Description

Cast iron frame steel gate

Technical field: the utility model relates to the backwater gate that uses in a kind of hydraulic engineering, particularly a kind of cast iron frame steel gate.

Background technology: at present, the steel gate that uses in engineerings such as urban water supply and drainage, agricultural drainage and irrigation, channel, small reservoir need be installed water stop rubber, because in use wearing and tearing of water stop rubber and aging so not only stagnant water effect is relatively poor, but also need to regularly replace; Simultaneously, itself also has corrosivity, so in the water supply and drainage process water quality is also had certain pollution.Common cast iron gate adopts the fitting face sealing, and stagnant water effect is good, but owing to the reason of cast iron quality can not be born high water pressure, uses under the hydrologic condition of high water head and be subjected to bigger restriction.

Summary of the invention: technical problem to be solved in the utility model is: provides a kind of door, frame fitting face stagnant water effect good, can bear use high hydraulic condition under, and pollution-free, anticorrosive, the cast iron frame steel gate of economy and durability.Its technical scheme is: a kind of cast iron frame steel gate, comprise gate slot and gate, and it is characterized in that: gate slot adopts the cast iron doorframe, or inlays cast iron or copper bar on doorframe; On the steel gate door body oblique type drift is housed, cooperates with eccentric backing pin or pressing plate on being installed in doorframe.Its technique effect is: owing to drawn the common advantage of steel gate and cast iron gate, gate slot adopts the cast iron doorframe, door body material uses steel plate to be welded into the steel gate, so can bear higher hydraulic pressure power as the ordinary steel gate, adopt the fitting face sealing, do not need to set up water stop rubber, reduce the resistance in the opening-closing process, can reach desirable stagnant water effect again, greatly reduce cost.On the door body of steel gate oblique type drift is housed, can be used, make a consideration close doorframe with the eccentric backing pin or the pressing plate that are installed on the doorframe.And between doorframe and the door body, be machined surface between the Men Tiyu pressing plate, because what adopt is the fitting face sealing, so the time is long more, its fitting face is just smooth more, and stagnant water effect is good more.Unlike water stop rubber, need regularly replace, in the water supply and drainage process, can not pollute water quality, and corrosion-resistant.

Fig. 3 is for being the vertical view of Fig. 1.

The specific embodiment:

As shown in Figure 1, 2, 3, cast iron frame steel gate is made up of gate slot and gate.Gate slot 1 adopts the cast iron doorframe, or inlays cast iron or copper bar 4 on doorframe.Door body 2 is welded into the steel gate by steel plate, on the steel gate door body oblique type drift 5 is housed, and cooperates with eccentric backing pin or pressing plate 3 on being installed in doorframe, makes the applying of Men Tiyu doorframe tightr.

Claims
