Abstract
The utility model discloses a corrosion-resistant stop valve. The corrosion-resistant stop valve comprises a valve body assembly and a valve core assembly, wherein the valve body assembly is provided with a valve base; the valve core assembly is provided with a valve core matched with the valve base; the valve base is positioned at the periphery of a medium passage to form an annular heave; and the valve core is provided with a corrosion-resistant annular sealing strip which is matched with the annular heave. The corrosion-resistant stop valve is provided with the corrosion-resistant annular sealing strip, so that a sealing surface has relatively high corrosion resistance, relatively high toughness and relatively strong erosion resistibility and can be normally used for a long time, thus ensuring long-time normal running of the corrosion-resistant stop valve and avoiding accidents; and the corrosion-resistant annular sealing strip is made of polytetrafluoroethylene or nylon and has relatively high toughness, so that the corrosion-resistant annular sealing strip is not required to be frequently maintained and the cost is saved.
Description
Technical field
The utility model relates to a kind of pipe valve annex, is a kind of corrosion-resistant stop valve.
Background technique
Valve is the requisite pipeline fittings of Chemical Manufacture, is used for opening and closing pipeline, adjust flux, the normal production of assurance device.
For general pipeline, structure and the performance of valve do not have specific (special) requirements, and cost is low is principle; And for the pipeline of outbalance, particularly for the aggressive medium pipeline in chemical process; Valve on its pipeline requires to have preferably corrosion-resistant, resistance to erosion and has sealing preferably.Therefore, this type of pipe valve generally adopts stop valve, and requires also to be different from general stop valve; Common stop valve generally adopts hard contact to reach sealing effect, and the sealing effect quality depends on the precision of sealing surface fully, even allows a small amount of the leakage.But for Korrosionsmedium, such as synthetic ammonia, need to have tight sealability; For corrosion class medium, generally between the spool of stop valve and valve seat adopt adaptability contact sealing, namely spool is provided with annular sealing strip, and the sealing band generally adopts the soft metal, and can deform after valve seat contacts, and reaches sealing effect; In practical application, soft metal toughness is inadequate, can be washed or corrode, and makes the sealing effect variation, thereby the operation period is shorter, needs often maintenance, thereby affects the normal operation of device.
Therefore, need to improve existing anticorrosion valve, sealing surface has corrosion resistance preferably, and has toughness preferably, and erosion resistibility is stronger, can use by long period, and the long period of assurance device normally moves, and, avoid the generation of security incident.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of corrosion-resistant stop valve, and sealing surface has corrosion resistance preferably, and having toughness preferably, erosion resistibility is stronger, can use by long period, the long period of assurance device normally moves, and, avoid the generation of security incident.
Corrosion-resistant stop valve of the present utility model, comprise valve component and mangetic core assembly, described valve component is provided with valve seat, and mangetic core assembly is provided with the spool that matches with valve seat, described valve seat forms annular protrusion around being positioned at medium channel, and spool matches with annular protrusion and is provided with anti-corrosion annular sealing strip.
Preferably, described anti-corrosion annular sealing strip is teflon or nylon.
Preferably, described spool is provided with the annular telescoping groove for chimeric anti-corrosion annular sealing strip, described anti-corrosion annular sealing strip and annular telescoping groove interference fit.
Preferably, described anti-corrosion annular sealing strip matches with annular protrusion and is provided with annular seal groove.
The beneficial effects of the utility model are: corrosion-resistant stop valve of the present utility model, be provided with anti-corrosion annular sealing strip, thereby make sealing surface have corrosion resistance preferably, and has toughness preferably, erosion resistibility is stronger, can use by long period, and the long period of assurance device normally moves, and, avoid the generation of security incident; Anti-corrosion ring packing strip adoption teflon or nylon material have toughness preferably, do not need regular maintenance, save cost.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure: the corrosion-resistant stop valve of the present embodiment, comprise valve component and mangetic core assembly, described valve component is provided with valve seat 1, mangetic core assembly is provided with the spool 2 that matches with valve seat, and described valve seat 1 forms annular protrusion 1a around being positioned at medium channel, and spool 2 matches with annular protrusion and is provided with anti-corrosion annular sealing strip 3, sealing strip adoption macromolecular material is made, good corrosion resistance, toughness is better, and specific Korrosionsmedium is had specific effect.
Preferably, described anti-corrosion annular sealing strip 3 is teflon or nylon.
Preferably, described spool 2 is provided with the annular telescoping groove 2a for chimeric anti-corrosion annular sealing strip, described anti-corrosion annular sealing strip 3 and annular telescoping groove interference fit; The structure that also can adopt the dovetail grooved to be pressed in the time of necessary prevents from, and further guarantees its usability.
Preferably, described anti-corrosion annular sealing strip 3 matches with annular protrusion 1a and is provided with annular seal groove 3a.
