Abstract
The utility model relates to a one-piece type internal thread ball valve. The one-piece type internal thread ball valve comprises a valve body, a valve core, valve seats, a valve rod, a regulating thread ring and a handle, wherein a through cavity is formed in the valve body, a channel is formed in the valve core, the inner wall of each valve seat is an inner arc wall, the valve core is suitable for rotating inside the valve seats, and positions where the inner arc walls make contact with the valve core form contact seal. The valve seats are two in number, the valve seats are relatively arranged inside the through cavity, and the valve core is arranged between the two valve seats. The regulating thread ring is connected with the valve body through threads and presses the valve seats, the upper end of the valve rod stretches out of the valve body and is connected with the handle, the lower end of the valve rod is connected with the valve core, a seal cushion is arranged at the connection portion of the valve rod and the valve core, and a bolt is arranged at a position, opposite to the bottom of the valve core, of the bottom of the valve core of the valve body. According to the one-piece type internal thread ball valve, corrosion influence, on the inside of the ball valve, from inner residual medium inside the ball valve can be effectively reduced, seepage of the ball valve is prevented, and the service life of the ball valve is prolonged.
Description
Technical field
The utility model relates to valve technology field, particularly a kind of single piece type internal thread ball valve.
Background technique
The faucet body of ball valve is spheroid, and the axis of spheroid is provided with manhole or passage.The flow direction that ball valve is mainly used to make cut-out, distributes and change medium in pipeline, it only needs to use very little moment of rotation just can close tightly pipeline the operation that spool is rotated 90 degree.Existing spool in use can cause a part of medium to be closed in the ball valve body cavity being in the gap between valve core outer surface and the valve body, thereby cause that residual medium is to the local failure electrochemical corrosion of valve internal surface in the ball valve body cavity, the rotten corrosion of residual medium self in the ball valve body cavity, and body cavity inner sealing medium causes damage because the extraneous factor superpressure expands to valve, thereby it is loosening to cause valve rod to be connected with spool, spool and valve base sealing are bad, ball valve is not closed completely, and shortens the working life of ball valve.
The model utility content
In order to overcome above shortcomings part in the prior art, the purpose of this utility model is to provide a kind of same form internal thread ball valve, and it can effectively reduce the inner residual medium of ball valve to the corrosion influence of ball valve inside, prolongs the working life of valve.
In order to reach above-mentioned purpose, the utility model adopts following concrete technological scheme: a kind of single piece type internal thread ball valve, comprise valve body, spool, valve seat, valve rod, adjust volution and handle, form cavity on the described valve body, form passage on the described spool, form on the inwall of described valve seat and be fit to the arc inner wall that described spool rotates within it, and described arc inner wall forms with the contacting point of described spool and contacts sealing, described valve seat is provided with two, be oppositely arranged in the described cavity, described spool is arranged between the two described valve seats, described adjustment volution and valve body are by being threaded and compressing valve seat, and described valve rod upper end is stretched out valve body and linked to each other with handle, and the lower end links to each other with spool, connection part at valve rod and spool is provided with sealing gasket, and the valve body cavity bottom right in the spool bottom is provided with bolt.
Described sealing gasket upper surface is the plane, and lower surface is curved surface, closely is connected with valve rod, spool.
Be provided with sealing gasket between described bolt and the valve body, closely connect by screw thread.
Compared with prior art, the utlity model has following outstanding advantage and effect: in the utility model, the fixed connection place of valve rod and spool because the protection of sealing gasket is arranged, is difficult for by residual dielectric corrosion; After valve uses a period of time, can turn on bolt and get rid of residual medium, reduce residual medium to the corrosion influence of sealing surface, prolong the working life of valve.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 1, the single piece type internal thread ball valve of present embodiment, comprise valve body 1, spool 2, valve seat 3, valve rod 4, adjust volution 5 and handle 6, form cavity on the described valve body 1, form passage on the described spool 2, form on the inwall of described valve seat 3 and be fit to the arc inner wall that spool 2 rotates within it, and described arc inner wall forms with the contacting point of described spool 2 and contacts sealing, described valve seat 3 is provided with two, be oppositely arranged in the described cavity, described spool 2 is arranged between the two described valve seats 3, described adjustment volution 5 and valve body 1 are by being threaded and compressing valve seat 3, described valve rod 4 upper ends are stretched out valve body 1 and are linked to each other with handle 6, and valve rod 4 lower ends are provided with sealing gasket 7 with the connection part that spool 2 is connected in valve rod 4 and spool 2 mutually, and the valve body 1 cavity bottom right in spool 2 bottoms is provided with bolt 8.
Described sealing gasket 7 upper surfaces are planes, and lower surface is curved surface, closely are connected with valve rod 1, spool 2, owing to be subjected to the protection of sealing gasket, the joint of valve rod and spool is difficult for by residual dielectric corrosion.
Be provided with sealing gasket 9 between described bolt 8 and the valve body 1, closely connect by screw thread, after valve uses a period of time, can turn on bolt, get rid of residual medium.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
