Abstract
The utility model relates to a side locking closing valve which comprises a valve and a locking device. The side locking closing valve is characterized in that an annular groove is arranged in the outer wall of a valve rod sleeve. The locking device comprises a lock, a lock sleeve and a valve rod cap, wherein the lock sleeve and the valve rod cap form an integral structure, the valve rod cap is covered on a valve rod sleeve, the lock sleeve is perpendicular to a pipe joint and the lock is arranged in the lock sleeve and is fixed to the lock sleeve by screws. When the lock is under a locking state, a lock bolt extends into the inner part of the annular groove. The utility model is arranged on a heating pipeline, so that the heating management for users is strengthened. The utility model has the advantage of convenient installation and use.
Description
The utility model relates to a kind of valve, particularly relates to a kind of valve with lock.
Northern China cold in winter all will be installed heating equipment, mainly is hot-water heating.The hot water of burning in boiler being given by the road units such as resident or enterprises and institutions, commerce by the heating room uses.Have two subject matters at present in management: the indivedual residents of the first do not hand over heating cost, and present heating network can not stop these not paying dues with user's heating of face, has stopped influencing other user; Its two be some residents or unit for some reason the long period do not need heating, stay out the long period or unit stops doing business as the resident, heating installation also will be supplied as usual, this not only wastes energy, and waste user's heating cost.For addressing the above problem in heating pipeline, on each user's inlet pipeline, adorn a valve.Give hot water or stop hot water with control.The user does not hand over heating cost just to close the disconnected hot water of valve.In addition, do not need heating person can apply for closing valve for some reason, stop heating, save user heating and take.In order not allow arbitrarily cut-off valve of user oneself, on valve rod, add protective housing at present, use plastic deformation, the disposable valve rod of sealing, destructiveness is removed protective housing during keying, changes new protective housing again; Another kind of way is to install fixed protection sleeve on valve rod additional, at protecting cover top locking plate, and the snap ring sealing.During keying, pull down the snap ring locking plate, operate with special tool.
The purpose of this utility model provides a kind of valve with lock, in order to the open and close of control valve, is beneficial to heat supply managing and energy saving.
The purpose of this utility model realizes by following technical proposals, that is:
The side chain locking valve comprises valve and locking device.Valve comprises valve body, valve rod, flap and pipe joint, and flap is a spheroid, is installed in the valve body, and pipe joint connects with screw thread and valve body after loading onto sealing gasket.Fixedly connected with the sphere-like flap in the lower end of valve rod, valve rod is positioned at valve stem casing, and valve stem casing and valve body are an overall structure.After putting into filler between valve stem casing inwall and the valve rod, suit upper gasket and pressure cap on valve rod.Be characterized on the valve stem casing of valve annular recess being arranged; Locking device comprises lock, lock tube and valve thimble.Lock tube and valve thimble are an overall structure, and the valve thimble button covers on the valve stem casing, and lock tube is vertical with pipe joint to be provided with, and lock is installed in the lock tube, and is screwed on lock tube.Lock is when being in locking states, and dead bolt stretches in the annular recess on the valve stem casing.
Valve is a prior art in the utility model, can be ball valve, gate valve, stop valve etc.
The utility model is not only applicable to be installed on the heating pipeline, also is applicable on the pipelines such as being installed in water supply, air feed.
Advantage of the present utility model is:
1, easy to install.When the utility model is installed on the heating pipeline, lock and lock nut can be done 360 degree rotations, be convenient to the on-the-spot operation of installing and opening and closing lock, not limited by the place state, when needs are closed or are driven valve, as long as open the lock with the key, dead bolt indentation lock body, valve thimble just can take off, and rotary valve rod just can be realized closing valve or driving valve.
2, Safety performance height, energy saving, the scientific management that helps heating.If the user does not hand over heating fee, but cut-off valve, and the user can not oneself open.If the user for some reason the long period need not heat and can apply for closing valve, but energy saving like this, the user can save heating fee, and the user can not open arbitrarily, must look for administrative staff to drive valve when driving valve.
3, simple in structure, easy to manufacture.
Fig. 1 is an a kind of embodiment's of the present utility model structural representation, and Fig. 2 is the A of Fig. 1---the A view.The utility model is described in further detail below in conjunction with accompanying drawing.
The side chain locking valve comprises valve and locking device.Valve comprises valve body 1, valve rod 2, spherical flap 3 and pipe joint 4, and spherical flap 3 is installed in the valve body 1, and pipe joint 4 is loaded onto sealing gasket 5 backs and connect with screw thread and valve body.Fixedly connected with ring-type flap 3 in the lower end of valve rod 2.Valve rod 2 is positioned at valve stem casing 6, and valve stem casing 6 is an overall structure with valve body 1.Between valve stem casing 6 inwalls and valve rod 2, be filled with filler 7, suit upper gasket 8 and pressure cap 9 successively on valve rod 2.Annular recess 10 is arranged on the outer wall of valve stem casing 6.Locking device comprises lock 11, lock tube 12 and valve thimble 13.Lock tube 12 is an overall structure with valve thimble 13, and valve thimble 13 buttons cover on the valve stem casing 6, and lock tube 12 is perpendicular to pipe joint 4, and lock 11 is installed in the lock tube 12, and is fixed on the lock tube 12 with screw 14.When lock 11 was in locking states, dead bolt 15 stretched in the annular recess 10.
