Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of ball valve, particularly relates to a kind of magnetic locking ball valve.
Background technique
Current, ball valve has been widely used in civil area and the industrial field such as oil, chemical industry, and particularly in civil area, ball valve has become controlling component main in residential building water supply, heating, supply air line.In order to strengthen the use management to pipeline user, fairly and reasonably realize Resource allocation and smoothing and conveyings such as water, gas, heat, when user in use there is arrearage, delay payment or the situation of operational failure time, the valve closing that regulatory authorities can take certain measure to be supplied water by the pipeline in user family, and only have and pay up expense completely as this user or just again this valve open supplied water to user again after fixing a breakdown.In order to strengthen effective management and the safety control of gas transmission being cut off to user, managerial department visits after locking outlet valve, does not allow user to open voluntarily, and this needs the valve being arranged on user side to have certain locking, anti-theft feature.
At present, in residential plumbing systems, property management personnel mainly use locking valve come when subscriber arrearage by valve closing thus stop supply water to user.Valve kind locking on present market is more, and a class adopts mechanical lock and mechanical key structure, but mechanical lock is easy to enter sand and earth, and key easily weares and teares, and therefore the valve of this structure is eliminated gradually.The another kind of valve being carrying magnetic and locking, by arranging magnetic patch and spring on valve body, utilize magnetic patch by handwheel and valve rod locking, and just can only be opened by the key with belt transect magnetic, but, most magnetic locking valve is being opened or all need to be with the key of magnetic to be connected on handwheel in using process just can operate always, and this mode brings great inconvenience to user.
Summary of the invention
The purpose of this utility model is the problems referred to above existed for prior art, proposes a kind of magnetic locking ball valve that user can regulate valve opening without the need to key under valve open state.
The purpose of this utility model realizes by following technical proposal:
A kind of magnetic locking ball valve, the ball core comprising valve body and be located in valve body and valve rod, described valve rod the inner is connected with ball core, described valve body upper end has joint, described valve rod outer end protrudes upward outside joint, described valve rod outer end is connected with handwheel, described handwheel is resisted against on joint, it is characterized in that, positioning hole one is provided with inside described handwheel, spring and magnetic patch one is provided with in described positioning hole one, the joint of described valve body is provided with the positioning hole two just right with positioning hole one, under the elastic force effect of spring, the inner of magnetic patch one to be stretched out bottom handwheel and is stretched in positioning hole two, this magnetic locking ball valve also comprises the key that can be connected on handwheel, in described key, correspondence is provided with the magnetic patch two contrary with magnetic patch one magnetic, the outer, upper end of the joint of described valve body offers curved spacing breach, when hand wheel rotating is positioned at the top of spacing breach to positioning hole one, the inner of described magnetic patch one extend in spacing breach under the elastic force effect of spring.
Under normal state, positioning hole one inside handwheel is positioned at the top of the spacing breach of the joint of valve body, it is outer and be positioned at spacing breach that positioning hole one is stretched out in the inner of magnetic patch one under the elastic force effect of spring, valve is in open mode always, now handwheel and valve body are in state free to rotate, rotating handwheel can be with ovable valve stem to rotate, thus controls the aperture of valve.
When subscriber arrearage or when there is operational failure, need valve closing and made by locking valve it use, key can be connected on handwheel by property personnel, the magnetic patch two contrary with magnetic patch one magnetic is provided with due to corresponding in handwheel, therefore under the effect of attraction force, magnetic patch one overcomes the elastic force effect of spring and is retracted in positioning hole one, then handwheel is rotated, positioning hole one to handwheel faces with the positioning hole two on valve body joint, key is taken off from handwheel, it is outer and stretch into positioning hole two that positioning hole one is stretched out in the inner of magnetic patch one under the elastic force effect of spring, now valve is in closed condition and simultaneously mutually locks and cannot operate between handwheel and the joint of valve body.When after subscriber payment or Failure elimination, key only need to be connected on handwheel and to make magnetic patch one again be positioned at the spacing breach of valve body by property personnel again.
When this magnetic locking valve supplies water to user in normal state, be positioned at the spacing breach on valve body due to magnetic patch one, handwheel is in rotatable state, and therefore user can regulate the aperture of valve without the need to key, easy to operate, save time.
In above-mentioned magnetic locking ball valve, described positioning hole one and the quantity of positioning hole two are two, two positioning holes one are symmetrically distributed in the both sides of valve rod, described key is strip, described key both sides have the bump in circular arc, the bottom of described bump is provided with mounting hole, and described magnetic patch two is fixed in mounting hole.
When needing to open handwheel, key is enclosed within handwheel, and ensures that the positioning hole one on the joint of mounting hole bottom the bump on key and valve body upper end faces.And the strip that key is square is mainly in order to save material, even in order to install magnetic patch two, the bump of circular arc also only need be arranged in key sidepiece correspondence.
In above-mentioned magnetic locking ball valve, described handwheel has two and protrude from handwheel upper end sidepiece and the connection lug raised up, bottom described key, correspondence is provided with two connecting grooves.
When connecting key, two that the connecting groove of two bottom key are aimed at outside handwheel connect lug, make connection lug be inserted into connecting groove, thus key and handwheel are linked together.
In above-mentioned magnetic locking ball valve, as another kind of situation, have two connection lugs protruded bottom described key downwards, described handwheel upper end face correspondence is provided with two connecting grooves.
When connecting key, two bottom key are connected lug aligning and is inserted in two connecting grooves of handwheel upper end face, thus key and handwheel are linked together.
In above-mentioned magnetic locking ball valve, bottom described handwheel, there is cavity, the connection part of described valve body is in cavity, the bottom of described cavity has the attachment hole identical with valve rod outer end configuration, described valve rod outer end is inserted in attachment hole, described handwheel top is provided with the circular hole be connected with attachment hole, is provided with connecting pin in described circular hole, and described connecting pin to stretch in attachment hole and is fixedly connected with valve rod outer end.
In attachment hole bottom the cavity that valve rod outer end is inserted into handwheel, form a fixed connection between valve rod and handwheel, then connecting pin is inserted and extend in attachment hole in the circular hole at handwheel top and be fixedly connected with valve rod outer end, such valve rod and handwheel are just connected together well.
Compared with prior art, this magnetic locking ball valve makes valve be in except locking states except utilizing key to operate handwheel when subscriber arrearage or fault, also by arranging spacing breach on the joint of valve body upper end, valve be in open mode normally supply water to user time, magnetic patch one is made to be positioned at spacing breach, ensure that user can regulate the aperture of valve when valve is in open mode, and without the need to connecting key in adjustment process, facilitate the operation of user well, save the time of user.
