Product Information
Product overview
Product introduction:
Globe valve is closed. (disc) along the valve seat centerline mobile.According to this mobile form of disc, seat and disc change in his itinerary directly proportional relationship.
Due to open or close the valve stem travel relatively short, and very reliable cutting function, and due to the change of his seat and disc stroke proportional relationship, is very suitable for the traffic regulation.Therefore, this type of valve is well suited for use as cut off or adjust and throttling.
Selection principle:
1, high temperature and high pressure medium or device appropriate chooses cut-off valve.Such as power plants, nuclear power stations, petrochemical system of high temperature and high pressure piping.
2, convection resistance is relaxed on the pipeline on the pipeline.Thinking about small place of pressure loss.
3, small valve can choose needle valve, instrument valve, the sampling valve, pressure gauge valve, etc.
4, there is flow control or pressure adjustment, but the adjustment accuracy is not high, and pipe diameter and the relatively small, such as nominal drift diameter of 50 mm or less piping, appropriate chooses.
6, desilication in bayer process of alumina production workshop, easy to coking on the pipeline, easy to choose seat can be separated type, body place, carbide seal once-through cut-off valve or once-through throttle valve.
7 on the water supply, heating, urban construction engineering, nominal menstruation smaller pipe, can be used as, balancing valve or plunger valve, the pipeline such as nominal drift diameter less than 150 mm.
The main advantages:
The most obvious advantage is: in the process of opening and closing, due to the friction between the disc in the valve sealing surface is smaller than gate valves, and wear resistance.Open altitude generally only a quarter of the seat channel diameter, so much smaller than gate valves.Typically on the valve body and disc only a sealing surface, thus making craft is good, easy to maintenance.Applicable temperature: 196 ℃ ~ 700 ℃ drive mode: manual, bevel gear drive, pneumatic, electric, hydraulic, pneumatic, hydraulic linkage, electro-hydraulic linkage: body material WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304 l), CF8M (316), CF3M, Ti (316 l).Choose different material, can be respectively suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and other media.
Features:
The pressure, temperature scope for fluid resistance small, big, medium flow direction is not restricted, sealed performance is good.
Construction matters needing attention:
1), the installation location, altitude, direction of import and export must comply with the design requirements, the connection should be firmly connected.
2), all kinds of manual valves installed on the thermal insulation pipe, handle shall not down.
3), a visual inspection must be conducted before installation of valve, the valve nameplate should be consistent with existing national standards 《universal signal valve》 GB 12220.For the working pressure is greater than 1.0 MPa and valve with the function of cutting off on ZhuGanGuan, strength and strict performance test should be done before the installation, qualified rear must use.Strength test, the test pressure is 1.5 times the nominal pressure, duration of not less than 5 min, shell and packing shall be no leakage of valve shall be qualified.Leak test, the test pressure is 1.1 times the nominal pressure;The duration of the test pressure in the test should comply with the standard of GB 50243 requirements, with no leakage for qualified for valve sealing surface.
The cut-off valve stem and valve seat sealing surface vertical axes.Open or close the valve stem travel relatively short, and very reliable cutting action, makes this valve very suitable for used as medium cut or adjust and throttling.
