Problems solved by technology

Through the above process, the molded valve and pipe connection have low rejection rate, high strength, light weight, and strong adaptability, which can meet the general requirements of civil and chemical equipment, but this solution only solves the manufacturing process of the valve body shell. It cannot reduce its manufacturing cost as a whole, and the overall process quality needs to be improved

Embodiment 1

[0025] Such as figure 1 As shown, the outer shape of the valve body shell 1 is a tee. The one on the right side of the valve body shell 1 is the water outlet base 5 for connecting the water outlet pipe of the faucet, the one on the upper side is placed on the valve core seat 4, and the one on the left side is placed on the water inlet base 2.

[0026] The spool seat 4 is used to place the spool, and three water holes are arranged at the bottom, wherein two water holes are respectively connected with cold water and hot water, and are used as water inlet holes of the spool. Another hole is to connect the spool mixed water outlet hole.

[0027] Water inlet base 2 is used to place water inlet pipe, and the water inlet hole that can connect cold and hot water pipe and the screw hole that is used for fixing whole valve body are arranged on its front. There is a copper pipe that can be placed on the reverse side of the water inlet base 2 for connecting the valve core seat 4. The w...

Embodiment 2

[0031] As shown in Figure 2, a manufacturing method of a faucet valve body, the valve body casing 1 is made of copper pipe extrusion: first pour tin metal inside the copper pipe, then put it into a mold, and use a 200-ton hydraulic press to extrude. After extrusion molding, the soft metals such as tin inside are melted, the valve body shell 1 and the water outlet base 5 are integrally formed at one time, the valve core seat 4 and the water inlet base 2 of the faucet valve body are cast separately through sand molds, and yellow The copper pipe is bent into the inner water pipe 3. In this embodiment, the valve body is a pull-out kitchen faucet with a guide tube 6 bent from a brass tube inside. There are four holes on the front of the water inlet base 2, which are respectively connected to the cold water inlet pipe, the hot water inlet pipe, the mixed water outlet pipe, and the screw holes for connecting the fixed valve body. First weld the inner water pipe 3 of the valve body t...

Abstract

The invention provides a method for manufacturing hydro-valve body, comprising the steps of: a. part machining; b. welding; and c. fine machining. And it moulds case, water inlet base, inner water pipe, valve core seat, and water outlet base and weld them together. And it compromises the advantages of hot forging and casting processes, saving large number of materials, reducing manufacturing cost and easy to control.

Description

technical field [0001] The invention relates to a method for manufacturing a faucet valve body, and belongs to the technical field of hardware product manufacturing methods. Background technique [0002] At present, the use of faucets has become more and more extensive. The valve body of the faucet is generally manufactured by casting and hot forging. The casting material has a high utilization rate, but poor quality is prone to blisters and cracks; The material utilization rate is low and the cost is high. With the price of metal materials rising frequently, how to improve the utilization rate of materials has become more and more important. [0003] The Chinese patent CN89105267.4 named universal valve, pipe connection expansion and compression molding process adopts the following technical scheme: including the final shaft of the press, expansion and compression materials, steel pipes and moulds, and is characterized in that the expansion and compression materials are pl...
