Abstract
A valve capable of being locked comprises a valve body, a valve core, a valve rod and a handle. A flange is arranged at the upper part of the valve body; the upper end of the valve rod extends out from the mesopore of the flange; two through-holes with the central angles of 90 DEG and used for locking as well as a limit pin are arranged on the flange; a matching cover is arranged at the front end of the handle; the matching cover is fixedly connected with the valve rod; and a through-hole used for locking and a fan-shaped notch are formed on the matching cover, wherein the through-hole is in alignment with the two through-holes of the flange when rotating. The utility model has the advantages of simple structure and low manufacture cost, and can be locked safely both in the open and the close states, thereby efficiently ensuring safe use of the valve; the utility model is suitable for household control and management of the fluid pipelines needing locking, such as water supply, heat supply, gas supply, oil supply and the like, and is particularly suitable to use on high risk pipelines, such as steam, high-pressure, poison and the like, in chemical plants; in addition, the valve can replace the prior universal ball valves; and the utility model has the advantages of prevention of burglary, misoperation prevention, convenient management and efficient energy conservation.
Description
Technical field
The utility model relates to valve field, specifically is a kind of valve of locking.
Background technique
Fluid line conveying management departments such as water supply, heat supply, air feed, fuel feeding in the user's corridor of being everlasting or outdoor installation main valve or divide valve shared or family, unit use for many families, prevent that one or two people from opening and closing pipeline valve privately, and the manager will add lockset usually on valve.Particularly in some special industries, as the steam in chemical plant, high pressure, when high-risk pipeline such as poisonous uses, be the life safety that ensures user, maintenance person etc., locking to valve just seems very necessary.The common valve mechanism of locking is to add a cover cap at valve, after earlier valve handle being pushed the state that opens or closes during use cover cap is covered, by the lockset locking, the valve volume of this structure is bigger again, occur misoperation during use easily, lose, antitheft and the operating characteristics of locking is bad.
Summary of the invention
The purpose of this utility model is the problem and shortage at above-mentioned existence, provides a kind of and is opening or closing the valve that can lock safely under the 2-way state.
The technical solution of the utility model is achieved in that a kind of valve of locking, comprise valve body, spool, valve rod and handle, the top of valve body is provided with flange, stretch out from the flange mesopore valve rod upper end, flange is provided with two through hole that is used to lock and the position limit pin that central angle becomes 90 °, the handle front end is provided with joins lid, joins lid and fixedlys connected with valve rod, joins to cover when being provided with rotation and can become 90 ° sector notch with through hole and the central angle that flange two through hole aligning is used to lock.
The linkage structure of flange and valve body can have various ways, can be to be made of one with valve body as flange; Or flange is connected with valve body by the split mode of inlaying assembling; Or flange by screw on valve body.
When wanting throttle down, stir handle, the through hole that the through-hole alignment flange of joining lid is provided with is joined a side that covers sector notch and is contacted with position limit pin and stop handle to continue rotation, the maintenance closed condition of can locking this moment; Otherwise, in the time will opening valve, stir handle, another through hole that the through-hole alignment flange of joining lid is provided with is joined another side that covers sector notch and is contacted with position limit pin and stop handle to continue rotation, and can lock and stay open state this moment.
The utility model has adopted on valve body top flange has been set, be provided with at the handle front end simultaneously and join lid, join by rotation and to cover at two through holes that the through hole that is provided with on it is provided with on the alignment flange respectively, effectively guarantee the safe handling of valve conveniently to lock.The utility model is simple in structure, low cost of manufacture, opening or closing under the 2-way state and can lock safely, be applicable to that the water supply that needs control of branchs family and management, heat supply, air feed, fuel feeding etc. need the fluid line control and management that lock, particularly on the steam in chemical plant, high pressure, high-risk pipeline such as poisonous, use, replaceable general ball valve now has antitheft, anti-misoperation, convenient management, the effective advantage of energy saving.
Below in conjunction with accompanying drawing the utility model is further described.
