Problems solved by technology
The valve is mainly composed of a valve body, a valve cover, and a valve disc. The parts of the valve are processed and manufactured by casting. When the valve cover is cast, the valve body can be formed by the cooperation of the molding sand and the mold. However, when making the molding sand Generally, only one pouring port is left to allow molten steel to enter the interior of the sand box, but the flow rate of molten steel and the speed of filling the cavity affect the molding of the casting. If the flow rate is slow, the speed of filling the cavity Slowness will affect the molding effect of the casting, resulting in insufficient pouring, inclusions, shrinkage cavity and shrinkage of the casting, which will affect the quality of the casting and make the casting unusable

Embodiment Construction
[0046] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0047] Such as figure 1 As shown, the communication valve casting includes the first ring part 100, the connecting part 200 and the second ring part 300 arranged in sequence from top to bottom, and the connection between the first ring part 100 and the connecting part 200 is provided with a Distributed reinforcing blocks 1 400, and circularly distributed reinforcing blocks 2 500 are arranged at the connection between the second ring portion 300 and the connecting portion 200 .
[0048] A preparation method for a communication valve casting, comprising the following steps:
[0049]S1, with sand
[0050] Put the raw sand, ...

The communication valve casting part comprises a first ring part, a connecting part and a second ring part which are sequentially arranged from top to bottom, first reinforcing blocks which are annularly distributed are arranged at the joint of the first ring part and the connecting part, and second reinforcing blocks which are annularly distributed are arranged at the joint of the second ring part and the connecting part; by arranging the first reinforcing block and the second reinforcing block, the stability of the overall shape of the valve deck can be improved, the possibility of deformation is reduced, the shape of the valve deck is kept unchanged, the connecting stability between all the parts is improved, and the overall service life of the valve deck is prolonged.
Description
technical field [0001] The invention belongs to the technical field of connecting valve castings, and in particular relates to connecting valve castings and a preparation method thereof. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. The valve is mainly composed of a valve body, a valve cover and a valve disc. The parts of the valve are processed and manufactured by casting. When casting the valve cover, the valve body can be formed by the cooperation of the molding sand and the mold. However, when making the molding sand When the box is used, generally only one pouring port is left to allow the molten steel to enter the interior of the sand box, but the flow rate of the molten steel and the speed of filling the cavity affect the molding of the casting. Slowness will affect...
