Embodiment Construction

[0020] The present invention is further described in conjunction with the following examples.

[0021] See eg Figure 1-3 A new claw-type pull-off valve is shown, including a first valve body 1, a first valve core 2, a second valve body 3 and a second valve core 4, and the first valve body 1 and the second valve core that are engaged with each other The valve body 3 is connected with the fluid pipeline through flanges 5 at both ends. The outer ends of the first valve body 1 and the second valve body 2 are fixed with a positioning plate 6, the side of the first valve core 2 and the second valve core 3 close to the positioning plate 6 is provided with a spring groove 7, and the spring groove 7 is placed There is a compression spring 8 , and the compression spring 8 passes through a positioning column 9 affixed to the first valve core 2 or the second valve core 4 , and the positioning column 9 passes through the positioning hole 10 on the positioning disc 6 . The setting of the...

Abstract

The invention discloses a novel claw type break valve which comprises a first valve body, a first valve plug, a second valve body and a second valve plug; locating discs are fixed at the outer ends of the first valve body and the second valve body; a spring groove is formed in one side, close to the corresponding locating disc, of the first valve plug; a spring groove is formed in one side, close to the corresponding locating disc, of the second valve plug; compression springs are placed in the spring grooves; a claw spring disc is arranged on the second valve body in a bulged manner; a claw fixing disc is fixed at the part, above the claw spring disc, of the second valve body through a plurality of inner hexagon screws; the number of claws is 8; the lower end of each claw stretches into a sleeve of the claw spring disc and is fixedly connected with a spring locating pin arranged in the sleeve correspondingly; pin shafts of the spring locating pins stretch into claw springs; the end of each spring locating pin pushes against one end of one corresponding claw spring; and the upper ends of the claws penetrate through the claw fixing disc and are clamped in grooves in the two sides of the buckling part of the first valve body and the second valve body. The break valve has the advantages of reliable movement, easiness in resetting, compact structure and the like.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a novel jaw type pull-off valve. Background technique [0002] Breakaway valves are widely used in chemical, pharmaceutical, oil refining, distillation, brewing, pulp and paper, steel processing, wastewater and many other industrial fields around the world. They are suitable for integration on loading arms to prevent vehicles from breaking due to accidental movement. The leakage of the product medium caused by the pipeline is equipped with a spring-loaded valve inside. The valve is activated by the pulling force of the hose. When the leakage occurs, the valve is automatically closed to prevent accidental breakage of road tank cars, railway tank cars or barges. . Existing breakaway valves often have disadvantages such as an overly complex structure, high manufacturing costs, difficult and long reset operations, and the like. Contents of the invention [0003] In view of the abo...
