Description

Ball valve

Technical field

The utility model relates to a kind of pipeline pipe valve, relates in particular to a kind of ball valve.

Background technique

Valve all is to open and close valve by special key before locking ball valve commonly used at present and the table with lock, in the residential quarter, key is placed on administration departments usually, opening and closing all want the property management personnel to operate, if under opening state, pipe leakage appears in the man of resident family, phenomenons such as gas leakage, user oneself can't in time close, if property personnel can not close in the short time, then can cause economic loss, even can cause danger, carry out the pipeline maintenance to the user simultaneously and also bring certain trouble to resident family, deprived user's the legal right to use, because lockhole is exposed to the outside for a long time, is easy to be stopped up by foreign material, is leaking, under the gas leakage situation, even there is key also can't close, then can result in greater loss and danger.

Summary of the invention

The purpose of this utility model, be exactly at the existing in prior technology deficiency, and provide a kind of ball valve, this ball valve can be opened or be closed voluntarily user at ordinary times, when actual when situations such as sub-district lack of water or arrearage occurring, administration departments can be locked, and does not have special-purpose management key resident family not open voluntarily behind the lock, has realized the multi-functional of real safe ready.

The technical solution of the utility model is: a kind of ball valve, comprise valve body, valve rod, valve ball and key, there is the handwheel valve gap to fixedly connected on described valve body top with valve rod, the one side of handwheel valve gap has groove, at least one block of magnet is arranged in the groove on described valve body, there is spring to be connected between the bottom of magnet and the valve body, handwheel valve gap inboard have with valve body in the corresponding groove of magnet, the insurance nail is arranged in the groove of described valve body another side, there is spring to be connected between the bottom of insurance nail and the valve body, the top of insurance nail is positioned at the groove that wheel valve covers, described key cover is connected on wheel valve and covers, have on the key with valve body on the corresponding key magnet of magnet.The user is voluntarily during the opening and closing ball valve at ordinary times, the insurance nail is positioned at the groove of handwheel valve gap sidewall, the user only need rotate the handwheel valve gap, wheel valve cover tape ovable valve stem and valve ball rotate, groove slides into another side from one side of insurance nail, then finished and opened or close, because the insurance nail is positioned at groove, can not lock when using at ordinary times by mistake, have only when administration departments needs the locking ball valve because of some reason, as long as press the insurance nail, rotate the handwheel valve gap then, make the magnet on the groove alignment valve body that wheel valve covers, the spring that is connected on the magnet can spring into magnet in the groove automatically, is locking states this moment, when needs are opened, then be connected on wheel valve with key cover and cover, the magnet on the key magnet alignment valve body is according to the principle of magnet homopolar-repulsion, magnet on the valve body ejects in handwheel valve gap groove, rotate the handwheel valve gap then, the insurance nail is entered in the groove, then finish breakdown action.

There is indication point in the outside of valve body described in the utility model.When the mark of opening, wheel valve covers out when closing with locking is aimed at indication point, be opening state, the mark of pass is closed condition when aiming at indication point, when the mark of lock is aimed at indication point, be locking states, has made things convenient for use like this.

A magnet is arranged on the valve body described in the utility model.Just can finish locking with a magnet, and lock back is more flexible when key operated.

Handwheel valve gap central part described in the utility model is a projection, and the cross section of projection is the circle that lacks on one side.Lock shape is difficult for being destroyed by other instrument like this, has guaranteed the safety of locking.

∪ shape leakproof circle is arranged between the top of valve rod described in the utility model and the valve body.Added a ∪ shape leakproof circle on the basis of original zero shape leakproof circle again, when zero shape was irised out existing leakage body or gas, ∪ shape leakproof circle can barrier liquid or the leaking outside of gas, and has prolonged the working life of ball valve.

The beneficial effects of the utility model are: have the handwheel valve gap to fixedly connected with valve rod on valve body top, the one side of handwheel valve gap has groove, at least one block of magnet is arranged in the groove on valve body, there is spring to be connected between the bottom of magnet and the valve body, have and the corresponding groove of magnet in handwheel valve gap inboard, the insurance nail is arranged in the groove of valve body another side, there is spring to be connected between the bottom of insurance nail and the valve body, the top of insurance nail is positioned at the groove that wheel valve covers, described key cover is connected on wheel valve and covers, have on the key with valve body on the corresponding key magnet of magnet.Such ball valve user opening and closing voluntarily, made things convenient for the user, do not need the same with ordinary ball valve manages, have only when needs the property management personnel can locking, during locking without key, just use special key during unlatching, realized that hand is opened, that hand closes, hand lock and lock back key are opened is multi-functional.Because ball valve of the present utility model does not have lockhole, can do not stopped up by foreign material and cause danger, and the special shape of handwheel valve gap can not destroyed by general instrument, strengthened the Security of valve, simultaneously ∪ shape leakproof circles that increase have prolonged the working life of ball valve more, and the user has reduced user cost in the process of using.
