Anti-freezing plunger valve for water injection pipeline

Abstract

The water injection pipeline anti-freezing plunger valve comprises a valve body, a reserved pipeline, a connecting block, a transmission gear and a reserved gear ring, the outer end of the valve body is fixedly connected with the reserved pipeline, the inner end of the reserved pipeline is rotationally connected with a movable blade, and the shaft end of the movable blade is wound with a conveying belt; an eccentric wheel is rotationally connected to the inner side of the reserved pipeline, and a containing groove and a water storage cavity are formed in the inner side of the reserved pipeline. According to the anti-freezing plunger valve for the water injection pipeline, as liquid in the reserved pipeline makes contact with movable blades, a reserved cavity in the inner end of a protective rolling cloth layer in an icing state is stably driven by the movable blades to move downwards through a transmission structure between an eccentric wheel and a movable part, and therefore two sets of abutting parts are pushed to move downwards to extrude reserved through holes; and the reserved sodium hydroxide makes contact with liquid in the water storage cavity to rapidly generate heat, heat supply treatment is conducted on the interior of the reserved pipeline, and therefore self-anti-freezing treatment is achieved.

Description

technical field [0001] The invention relates to the technical field of plunger valves, in particular to an antifreeze type plunger valve for a water injection pipeline. Background technique [0002] As a common valve structure, the plunger valve is popularized and loved by users for its better structural characteristics, so the production process of the plunger valve is also more rigorous, but the existing plunger valve still has certain defects , for example: [0003] For example, the plunger valve with the publication number of CN201053504, the sealing between the valve stem and the valve body, the sealing between the plunger valve core and the valve seat, all adopt O-rings, and they are double-sealed, with good sealing effect and no leakage, but In the process of the existing plunger valve working outdoors, in the case of long-term freezing, the liquid supply pipeline is very prone to freezing, which in turn causes the liquid transmitted inside to be frozen, resulting in...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an antifreeze plunger valve for water injection pipelines to solve the phenomenon that the liquid supply pipeline is extremely prone to freezing in the case of long-term freezing during the outdoor work proposed in the background technology , and then lead to the phenomenon of freezing of the liquid transferred inside it, resulting in the state of freezing and blocking the pipeline, which requires the user to disassemble the equipment and go deep into the interior for processing. It is relatively fixed in the external state, and cannot automatically Adjusting the flow rate of its supply liquid makes it easy to cause the problem of insufficient water pressure supply in winter due to temperature.
