Blue disk is slidably and sealingly connected with the inner flange, and bullet block, the bullet block are provided between the outward flange disk and inner flange
Material be elastomeric material, be threaded with lock ring on the valve body on the outside of the outward flange disk, it is real by rotating the lock ring
The existing outward flange disk moves left and right adjusting.
Wherein, stuffing-box is provided between the valve deck and valve rod, stuffing-box cap has been connected through a screw thread above valve deck.
Wherein, the stuffing-box is graphite block, and the graphite block is sandwich construction.
Compared with prior art, beneficial effects of the present invention are that the company at pipe valve valve both ends can be adjusted by said structure
Spreading degree, the distance of outward flange disk and inner flange is adjusted by rotating lock ring.When Pipe installing, it is necessary to when fine setting, lead to
Overregulate, it is possible to which accurate installation, using effect are good.

Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It is it should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
It should be noted that " connection " described herein and the word for expressing " connection ", such as " being connected ",
" connected " etc., was both directly connected to including a certain component and another component, also passed through miscellaneous part and another portion including a certain component
Part is connected.
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.
As shown in Figure 1, the present invention provides a kind of pipe valve valve with adjustment structure, including valve body, valve seat, flap, valve
Lid, valve body are provided at both ends with inner flange, are socketed with outward flange disk on the outside of the inner flange, the outward flange disk with it is described
Inner flange is slidably and sealingly connected with, and bullet block is provided between the outward flange disk and inner flange, the material of the bullet block is rubber
Glue material, is threaded with lock ring on valve body on the outside of the outward flange disk, the outer method is realized by rotating the lock ring
Blue disk moves left and right adjusting.
Wherein, stuffing-box is provided between the valve deck and valve rod, stuffing-box cap has been connected through a screw thread above valve deck.
Wherein, the stuffing-box is graphite block, and the graphite block is sandwich construction.
The connection length at pipe valve valve both ends can be adjusted by said structure, by rotate lock ring adjust outward flange disk with it is interior
The distance of ring flange.When Pipe installing, it is necessary to when fine setting, pass through adjusting, it is possible to which accurate installation, using effect are good.
The pipe valve valve body includes valve body, valve seat, flap, valve deck, stuffing-box, stuffing-box cap, the valve deck and valve body
It is threadedly coupled, stuffing-box is provided between valve deck and valve rod, stuffing-box cap has been connected through a screw thread above valve deck,
The stuffing-box is graphite block, and the graphite block is sandwich construction, graphite block is arranged to sandwich construction, in more piece
Under the structure that stacks.For original graphite block to be overall, its stress surface is upper and lower ends face, after being changed to the structure that more piece stacks, its
Stress surface increase, crushing resistance enhancing, meanwhile, sealing performance also strengthens, easy to industrially promotion and application.
In addition, valve rod connection and safe dish structure, the safe dish structure include manual disk, pressure connecting disk, compression spring, on
Fluted disc, lower engagement fluted disc, clutch plate are engaged, is socketed with clutch plate on the valve rod, clutch plate is synchronized with the movement with valve rod, clutch plate
Upper end is provided with lug boss, and lug boss is socketed with manual disk, and the manual disk is slidably connected with lug boss, and manual disk upper end passes through
Compression spring is connected with pressure connecting disk, and the pressure connecting disk is threadedly coupled with the lug boss of clutch plate, and pressure is adjusted by adjusting the pressure connecting disk
The compression degree of spring, and then adjust the compression spring elastic force suffered by manual disk, the manual disk upper surface be provided with it is cricoid under
Fluted disc is engaged, manual disk lower face is provided with engagement fluted disc, and the lower engagement fluted disc and upper engagement fluted disc are used in combination, nibble
Close connection.
Position of the pressure connecting disk on valve rod is regulated, so as to adjust the pressure size of compression spring, rotary manual disk drives driven
Disk moves, and clutch plate is fixedly connected with valve rod, so as to be rotated with ovable valve stem, realizes the opening and closing of flap.Manually disk
Upper engaging tooth drive the lower engaging tooth of clutch plate so as to which rotary valve rod realizes the opening and closing of shut-off valve, by adjusting compression spring
Pressure size, the torque size being applied on valve rod can be adjusted, when operational torque be more than upper engaging tooth and lower engaging tooth it
Between frictional force when, upper engaging tooth is slided from lower engaging tooth, is departed from, and manual disk can not drive driven disc spins, avoid
Because torque is excessive damage valve.
In addition, the flap is connected to the lower end of valve rod, flap includes cylindrical portion and tapered portion, and the valve seat is L-type, institute
The longitudinal surface that cylindrical portion is stated with the L-type valve seat is connected, the tapered portion and the inclined-plane of L-type valve seat junction.
Such structure design cause flap two faces and valve seat two faces connect, sealing effect more preferably, secondly, if
Put L-type slot structure so that flap forms torrent when closure in L-type groove, forms very big scouring force, can be effective
Faying face is cleaned, ensure that the effect of sealing.
Although each conception of species has been described in detail, it will be appreciated by a person skilled in the art that for the various of those concepts
What modifications and substitutions can be achieved under the spirit disclosed by the invention integrally instructed.Those skilled in the art use common skill
Art can just realize the present invention illustrated in detail in the claims in the case of without undue experimentation.It is also understood that
It is that disclosed specific concept is merely illustrative, is not intended to limit the scope of the present invention, the scope of the present invention is by appended
The four corner of claims and its equivalent determines.
