Technical field:
The utility model relates to a kind of ball valve, and particularly a kind of three pieces type internal thread ball valve has anti-leak, changes characteristics such as convenient.
Background technique:
At present, traditional three pieces type internal thread ball valve on industries such as oil, rock gas, chemical industry, generally include valve body, valve seat, valve rod and spheroid, valve rod one end passes fixedlying connected of valve body and spheroid, the valve rod the other end is provided with handle, be provided with valve seat in the valve body, spheroid is arranged between two valve seats, valve seat is provided with and the ball seal face, be provided with sealing gasket between valve body and the valve gap, owing to often use, in the long-term impact flow process of medium, spheroid and valve base sealing surface abrasion are out of shape, and influence the working life of product.
The model utility content:
At the technical deficiency of existing the said goods, the purpose of this utility model just provides a kind of three pieces type internal thread ball valve, can realize anti-leak, change purpose easily.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of three pieces type internal thread ball valve, comprise valve seat, valve body, spheroid, valve rod and handle, described valve body is provided with flow pass and flow channel, be provided with valve pocket between flow channel and the flow pass, valve pocket is equipped with valve seat near flow channel one end with near flow pass one end, is provided with spheroid between the valve seat; Also be provided with valve rod hole on the described valve body, valve rod passes valve rod hole, and the flat notch on valve rod one end and the spheroid patches to connect and compose circumferentially and is located by connecting, and the valve rod the other end is provided with handle; Described valve seat is teflon or teflon glass fibre, and valve seat is provided with the sealing surface with ball seal, constitutes soft seal.
The utility model further is set to: described valve body is connected to form by bolt by left valve gap, right valve gap and main valve body, and described main valve body is provided with valve pocket and valve rod hole, and left valve gap is provided with flow pass, and right valve gap is provided with flow channel.
The center line of described flow pass, flow channel and valve pocket is on same straight line.
The utility model further is set to: described valve rod is provided with annular flange flange near the valve rod hole bottom, is provided with thrust pad between this annular flange flange and the valve rod hole bottom; Described valve rod is provided with gland near valve rod hole top, is provided with filler between this gland and the valve rod hole top.
The utility model further is set to: also be provided with lock dog on the described handle.
The utility model beneficial effect: anti-leak, replacing are conveniently.
Description of drawings:
Fig. 1 is the utility model overall structure schematic representation;
Illustrate 1 among the figure, bolt 2, left valve gap 3, right valve gap 4, valve seat 5, spheroid 6, main valve body 7, thrust pad 8, filler 9, valve rod 10, gland 11, handle 12, lock dog.
Embodiment:
According to shown in Figure 1, the utility model provides a kind of three pieces type internal thread ball valve, and it is made up of bolt 1, left valve gap 2, right valve gap 3, valve seat 4, spheroid 5, main valve body 6, thrust pad 7, filler 8, valve rod 9, gland 10, handle 11, lock dog 12.Described valve body is provided with flow pass and flow channel, is provided with valve pocket between flow channel and the flow pass, and valve pocket is equipped with valve seat 4 near flow channel one end with near flow channel one end, is provided with spheroid 5 between the valve seat 4; Also be provided with valve rod hole on the described valve body, valve rod 9 passes valve rod hole, and the flat notch on valve rod 9 one ends and the spheroid 5 patches to connect and compose circumferentially and is located by connecting, and valve rod 9 the other ends are provided with handle 11; Described valve seat 4 is teflon or teflon glass fibre, and valve seat 4 is provided with the sealing surface with spheroid 5 sealings, constitutes soft seal.Because valve seat 4 adopts teflon or teflon glass fibre, has antiwear characteristic, be that long-time use also can be played good sealing effect, be provided with spheroid 5 between flow channel and flow pass and the valve pocket and cooperate the curved surface that forms sealing, ball valve can both play good sealing effect under the situation of closing.
Described valve body of the present utility model is connected to form by bolt 1 by left valve gap 2, right valve gap 3 and main valve body 6, described main valve body 6 is provided with valve pocket and valve rod hole, left side valve gap 2 is provided with flow pass, right valve gap 3 is provided with flow channel, the center line of described flow pass, flow channel and valve pocket is on same straight line, can better prevent the dielectric leakage in the valve body, it is also convenient to change.
Valve rod 9 of the present utility model is provided with annular flange flange near the valve rod hole bottom, is provided with thrust pad 7 between this annular flange flange and the valve rod hole bottom; Described valve rod 9 is provided with gland 10 near valve rod hole top, is provided with filler 8 between this gland 10 and the valve rod hole top, can better prevent the dielectric leakage in the valve body.Also be provided with lock dog 12 on the handle 11 of the present utility model simultaneously, be user-friendly to.
