Problems solved by technology

[0002] At present, all kinds of water pump control valves, because the shaft design does not adopt the variable cross-section structure design with small front and large rear, so the valve disc takes a long time in the closing process, and the water hammer at the final closing cannot be prevented. Effectively reduce and protect the water pump

Embodiment Construction

[0008] A manufacturing process of a direct-flow water pump control valve with small water hammer mainly includes the following steps: a tapered shaft and connecting bolts are provided between the outlet valve disc and the inlet valve disc, and are connected by nuts. The structure of the straight-line water pump control valve with small water hammer produced by the present invention will be further described in detail below in conjunction with the accompanying drawings. Referring to the accompanying drawings, it is a direct-flow water pump control valve with small water hammer. The valve body 1 is provided with an inlet port 17 and an outlet port 18. The inlet port 17 is provided with an inlet valve seat 11. The inlet valve seat 11 and the inlet valve disc 10 form a In the first level of sealing, the inlet disc 10 is set in the valve inner sleeve 16 on the valve body 1, the inlet valve disc sleeve 8 is set between the inlet valve disc 10 and the valve inner sleeve 16, and the va...

Abstract

The invention discloses a preparing craft of straight-flow type water pump controlled valve of small water hammer, which comprises the following steps: providing a cane axle and connected bolt between outlet valve clad and inlet valve clad; connecting through nut; getting the product. This invention possesses reasonable craft and good idea, which can be spreaded widely.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a manufacturing process of a water pump control valve. Background technique [0002] At present, all kinds of water pump control valves, because the shaft design does not adopt the variable cross-section structure design with small front and large rear, so the valve disc takes a long time in the closing process, and the water hammer at the final closing cannot be prevented. Effectively reduce and protect the water pump. Contents of the invention [0003] The object of the present invention is to provide a manufacturing process for a once-through water pump control valve with small water hammer that can effectively overcome the above defects and effectively reduce the water hammer at the final closing. [0004] In order to achieve the above object, the present invention adopts the following technical scheme: a manufacturing process of a direct-flow water pump contro...
