YY-TZS-1 mechanical explosion-proofing passage ball indicator

Mechanical explosion-proofing passage ball indicator is a necessary equipment in pipeline pigging and descaling process in explosion proof site. It integrates the advantages of each indicator and adds its own characteristic functions. It has many advantages such as direct instruction, stable performance and convenient use, providing users with more satisfactory service.

YY-TZS-2 anti-explosion explosion-proofing passage ball indicator

YY-TZS-2 anti-explosion explosion-proofing passage ball indicator is two patent products independently developed by our company (patent number: ZL2006.20088894.5 and ZL 2013 2 0801126.x). The patentee is Shenyang Yongye Industrial Co., LTD.

YY-TZS-3 Flange connected explosion-proof passage-ball indicator

Flange-connected passage ball indicator is composed of flange-connected mechanical contact main body and LCD explosion-proof indicator display head (YY-TZS). It has the characteristics of direct instruction, automatic reset of mechanical part, manual reset of display part and signal transmission. The indicator can be displayed normally when the pig is passed in both the forward and reverse directions in the pipeline, and the pig passing situation in the pipeline can be conveyed through the mechanical structure at a fixed position on the pipeline, so as to provide the operator with information and guide the conversion of the process flow.

YY-TZS-4 Pressure removable explosion-proof mechanical passage ball indicator

Pressure removable explosion-proof mechanical passage ball indicator is composed of mechanical drive body, stub, diameter ball valve, base flange (short connection), explosion-proof digital display, with pressure removable, direct instruction, automatic reset of mechanical part, manual reset of display part and signal transmission characteristics. The indicator can be displayed normally when the pig is passed in both the forward and reverse directions in the pipeline, and the pig passing situation in the pipeline can be conveyed through the mechanical structure at a fixed position on the pipeline, so as to provide the operator with information and guide the conversion of the process flow.

YY-TZS-5 Standard flag type passage ball indicator

Flag (sign) type mechanical passage ball indicator, is composed of mechanical contact main body, display mechanism (sign indication), with direct instruction, automatic reset of the mechanical part, manual reset of the display part and so on. The indicator can be displayed normally when the pig is passed in both the forward and reverse directions of the pipeline, and the pig passing situation in the pipeline can be conveyed through the mechanical structure at a fixed position on the pipeline, so as to provide information and guide the operator to change the process inversion.

YY-TZS-6 flange connected flag type passage ball indicator

Flanged connected flage type mechanical passage ball indicator is composed of mechanical contact main body, hoist indicator head, with direct instruction, mechanical part automatic reset, display part manual reset and other characteristics. The indicator can be displayed normally when the pig is passed in both the forward and reverse directions in the pipeline, and the pig passing situation in the pipeline can be conveyed through the mechanical structure at a fixed position on the pipeline, so as to provide the operator with information and guide the conversion of the process inversion.

The flag (sign) type detachable mechanical passage ball indicator

The flag (sign) type detachable mechanical passage ball indicator is composed of mechanical drive main body, diameter ball valve, base flange (short connection), display mechanism (sign indication), with pressure detachable, direct indication, automatic reset of mechanical part, manual reset of display part and so on. Within the pipeline, are two directions through pig indicator can display properly, can be on the line orientation, designated by the mechanical structure of convey the line through the situation of pig, provide the operator with information and guide the process of transformation, mechanical failure occurs in the product can be realized with pressurized disassembly, is advantageous for the mechanical fault of timely maintenance.
