Problems solved by technology

[0003] In the past, although the globe valve industry used aluminum or aluminum alloy instead of brass to process the theory of globe valves, such as the Chinese patent CN00202042. The quality, processing suitability, qualification rate and cost of alloy valves meet the requirements of mass production, especially the main parts of the valve are difficult to process by conventional processes, and aluminum or aluminum alloy valves cannot be actually put into production. This is only a theory

Embodiment 1

[0019] FIG. 1 is a structural schematic diagram of a globe valve adopting an integral forging structure in the prior art. The overall forging structure is a common structure and processing technology for copper material globe valves, but this overall structure processing technology is relatively difficult, and it is not suitable for aluminum and steel materials.

[0020] Figure 2 is a schematic structural view of the aluminum alloy split globe valve in the present invention. Its main parts are different from the prior art products, and are mainly composed of split valve body 1, joint 2, flange 3, and copper pipe 4. The above-mentioned parts are made of high-strength aluminum alloy, and then threaded The connection is combined with welding or direct welding, which simplifies the processing technology of the product. As a preference, the valve body 1, the joint 2 and the flange 3 are processed by aluminum alloy profiles such as round and square. Forging, casting and other proc...

Embodiment 2

[0022] FIG. 3 is a schematic structural diagram of a steel material split globe valve in the present invention. Its main parts are different from the existing technical products, mainly composed of split valve body 1, joint 2, flange 3, and copper pipe 4. The above parts are made of free-cutting steel. On the premise of ensuring product strength , which can meet the processing requirements of the product; each component adopts welding combination, which obviously simplifies the processing technology of the product. The valve body 1, the joint 2 and the flange 3 are processed with round and square steel profiles or plates, and the raw materials are easy to prepare; completely avoiding the forging, casting and other processes required for the overall steel valve, simplifying the production equipment, simplifying the process, The process is simplified and fully meets the needs of mass production. The valve body 1 and the copper pipe 4 are connected by welding. This embodiment a...

Abstract

The invention discloses an air-conditioner shutoff valve and the machining method thereof, comprising main parts and auxiliary parts, where the main parts comprise main valve body, joint, flange and copper pipe, where they each adopt a split structure, and are firstly machined, separately, and then combined by welding after screwed mutually or directly combined by welding, and the main valve body, the joint and the flange can be made of cheap aluminum alloy or steel. The invention largely simplifies difficulty in machining process, beneficial to batch production, largely reduces cost of raw materials, saves resources, reduces environmental pollution, and simplifies the process because of no need of processing the three wastes.

Description

【Technical field】 [0001] The invention relates to an air conditioner, in particular to a stop valve for an air conditioner. 【Background technique】 [0002] At present, the stop valves used in air-conditioning equipment are all made of brass forging blanks, and then processed by machining, welding combination, surface pickling treatment and other processes. However, the cost of using brass to process the globe valve is too high, resulting in a waste of resources; and the brass globe valve has pickling environmental pollution during the production process and needs to be treated with three wastes. The main parts of the current stop valve are all directly forged and pressed with the overall structure. [0003] In the past, although the globe valve industry used aluminum or aluminum alloy instead of brass to process the theory of globe valves, such as the Chinese patent CN00202042. The quality, processing suitability, pass rate, and cost of alloy valves meet the requirements o...
