Lower threaded stem pipe valve valve etc., they have durable, Lift less, manufacture be easy, be easy to maintenance, be applicable not only in it is low
The characteristics of pressing, and being suitable for high pressure.
In the prior art, existing valve the installation when, the pipeline length in reserve of two sides is inadequate frequent occurrence
Problem has seriously affected the installation and use of valve.
Utility model content
For the above-mentioned problems in the prior art, the present invention provides a kind of pipe valve valve with adjustment structure.
To realize the purpose of this utility model, the utility model provides a kind of pipe valve valve with adjustment structure, including
Valve body, valve seat, flap, valve deck, the both ends of valve body are provided with inner flange, are socketed with outward flange disk on the outside of the inner flange,
The outward flange disk is slidably and sealingly connected with the inner flange, is provided with bullet block between the outward flange disk and inner flange,
The material of the bullet block is rubber material, lock ring is threaded on the valve body on the outside of the outward flange disk, by rotating institute
That states that lock ring realizes the outward flange disk moves left and right adjusting.
Wherein, it is provided with stuffing-box between the valve deck and valve rod, has been connected through a screw thread stuffing-box cap above valve deck.
Wherein, the stuffing-box is graphite block, and the graphite block is multilayered structure.
Compared with prior art, the beneficial effects of the utility model are to pass through above structure adjustable pipe valve valve both ends
Connection length, by rotation lock ring adjust outward flange disk at a distance from inner flange.Work as Pipe installing, need to finely tune when
It waits, passes through adjusting, so that it may which accurate installation, using effect are good.

Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
It should be noted that " connection " described herein and the word for expressing " connection ", as " being connected ",
" connected " etc. had both included that a certain component is directly connected to another component, and had also included that a certain component passes through other component and another portion
Part is connected.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
As shown in Figure 1, the utility model provides a kind of pipe valve valve with adjustment structure, including valve body, valve seat, valve
Valve, valve deck, the both ends of valve body are provided with inner flange, are socketed with outward flange disk, the outward flange disk on the outside of the inner flange
It is slidably and sealingly connected with the inner flange, bullet block, the material of the bullet block is provided between the outward flange disk and inner flange
Material is rubber material, is threaded with lock ring on the valve body on the outside of the outward flange disk, realizes institute by rotating the lock ring
That states outward flange disk moves left and right adjusting.
Wherein, it is provided with stuffing-box between the valve deck and valve rod, has been connected through a screw thread stuffing-box cap above valve deck.
Wherein, the stuffing-box is graphite block, and the graphite block is multilayered structure.
By the connection length above structure adjustable pipe valve valve both ends, by rotation lock ring adjust outward flange disk with it is interior
The distance of ring flange.When working as Pipe installing and need to finely tune, pass through adjusting, so that it may 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, has been connected through a screw thread stuffing-box cap above valve deck,
The stuffing-box is graphite block, and the graphite block is multilayered structure, multilayered structure is set by graphite block, in more piece
Under the structure that stacks.Original graphite block is entirety, and stress surface is upper and lower end faces, after being changed to the structure that more piece stacks,
Stress surface increases, crushing resistance enhancing, meanwhile, sealing performance also enhances, and is convenient for industrially promotion and application.
In addition, valve rod connection and safe dish structure, the safe dish structure include manual disk, pressure connecting disk, pressure spring, on
Fluted disc, lower engagement fluted disc, driven disc are engaged, is socketed with driven disc on the valve rod, driven disc is moved synchronously with valve rod, driven disc
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
Pressure spring is connected with pressure connecting disk, and the pressure connecting disk is threadedly coupled with the lug boss of driven disc, adjusts pressure by adjusting the pressure connecting disk
The compression degree of spring, and then adjust pressure 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 end surface 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, to adjust the pressure size of pressure spring, rotary manual disk drives driven
Disk movement, driven disc are fixedly connected with valve rod, to rotate with ovable valve stem, realize the opening and closing of flap.Pass through manual disk
Upper engaging tooth drive driven disc lower engaging tooth to rotary valve rod realize shut-off valve opening and closing, pass through adjust pressure spring
Pressure size, the adjustable torque size being applied on valve rod, when operational torque be greater than upper engaging tooth and lower engaging tooth it
Between frictional force when, upper engaging tooth is slided from lower engaging tooth, be detached from and go out, manual disk is unable to drive driven disc spins, avoids
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
It states cylindrical portion to connect with the longitudinal surface of the L-type valve seat, the inclined-plane of the tapered portion and L-type valve seat junction.
Such structure designs so that two faces of flap and two faces of valve seat connect, sealing effect more preferably, secondly, setting
L-type slot structure is set, so that flap when closure, forms torrent in L-type slot, forms very big scouring force, it can be effective
Faying face is cleaned, ensure that the effect of sealing.
