Problems solved by technology

[0003] The current production process of emergency breakaway valves requires the use of lathe equipment. The disadvantages are: first, at present, most factories use lathes to process the breakaway valve body, which can only be produced in small batches, and the production efficiency is low; second, The precision of the processed and formed products is not high, which affects the stability and service life of the products; third, the labor intensity of the workers is high, and a lot of manpower, time and materials are wasted at the same time, which affects the economic benefits

Embodiment Construction

[0019] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] A production method of an emergency pull-off valve, comprising the following production steps:

[0021] 1) Perform multi-station stamping processing through the progressive die to process the main valve body of each breakaway valve;

[0022] 2) Through forging, each flange is processed;

[0023] 3) Weld the main valve body of the breakaway valve with the flange to obtain the valve body structure of the breakaway valve.

[0024] The main valve body of the breakaway valve in step one is obtained by stamping. Specifically, the mai...

Abstract

The invention relates to the technical field of valve production and particularly relates to a production method of an emergent cut-off valve. The production method comprises the following steps: using a stainless steel plate as a raw material, carrying out stamping forming on the raw material to form a main valve body of the cut-off valve, carrying out forging machining to obtain a flange disc, and then welding the main valve body and the flange disc to obtain the valve body. The method is simple, practical and reliable. The strength and impact resistance of the produced cut-off valve are improved, the quality is substantially improved, the service life is long, a great effect is shown in actual production application, the procedures are simple, the operation is safe, the labor intensityof operators is reduced, and the production efficiency and benefit are greatly increased.

Description

technical field [0001] The invention relates to the technical field of valve production, in particular to a production method of an emergency pull-off valve. Background technique [0002] The emergency breakaway valve (emergency breakaway device) can prevent leakage accidents caused by accidental breakage of pipelines, realize the protection of pipelines, materials and personnel, ship to shore unloading, supply ship material supply transportation, road and railway tank loading and unloading, and Other stationary and mobile fluid storage installations require the use of emergency breakaway valves. [0003] The current production process of emergency breakaway valves requires the use of lathe equipment. The disadvantages are: first, at present, most factories use lathes to process the breakaway valve body, which can only be produced in small batches, and the production efficiency is low; second, The precision of the processed and formed products is not high, which affects the...
