Description
Technical field
The utility model relates to a kind of control valve of pipeline connection area, particularly relates to a kind of repid cut-off valve.
Background technique
As everyone knows, the medium in pipeline once reveal, particularly poisonous and hazardous gas, fluid leakage, if close not in time consequence by hardly imaginable.At present, traditional method controls by being closed in the valve arranged in pipeline, the general operation time is longer, and particularly the shut-in time can be longer, more difficult under without special tool, valve corrosion, field condition harsh conditions, the harm caused and secondary disaster larger.
Summary of the invention
The technical problem that the utility model solves provides a kind of repid cut-off valve for pipeline connects, and quick closedown can reveal pipeline, stop ducted medium to leak outside, reduce the loss, and reduces medium and leak and work the mischief and the possibility of secondary disaster.
In order to achieve the above object, the utility model realizes by the following technical solutions:
Repid cut-off valve, comprise valve body, spring, spool, valve gap, O RunddichtringO one, O RunddichtringO two, hose connector, fast plug in folder, it is characterized in that, described valve body one end is provided with the circular cylindrical cavity of mounting spring and spool, the internal diameter of the other end is provided with taper hole and coordinates with the centrum section on valve gap, with O RunddichtringO two seal, external diameter coordinates with the circular groove on valve gap, seal with O RunddichtringO one; Described fast folder of inserting is inserted in the groove on valve body by the through hole on valve gap, valve body and valve gap is fixed as one.
One end of described spring is fixed on valve body, and the other end presses spool and withstands on the end (opening state) of bonnet central straight hole section or withstand on the end (closed condition) of valve body 1 circular cavity.
The center straight hole section of described valve gap one end is provided with notch, and the other end is provided with hose connector.
The described fast U-shaped plugging in folder dehisces there is certain elasticity, and its distance L is slightly less than valve body upper groove outer diameter D.
Compared with prior art, the beneficial effects of the utility model are:
1) quick closedown can reveal pipeline, stop ducted medium to leak outside, reduce the loss, reduce medium and leak and work the mischief and the possibility of secondary disaster;
2) structure is simple, easy to install, without the need to special tool, is applicable to the middle-size and small-size pipeline that pressure medium is less than 30MPa.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, the utility model relates to a kind of repid cut-off valve, comprise valve body 1, spring 2, spool 3, valve gap 4, O RunddichtringO 1, O RunddichtringO 26, hose connector 7, fast plug in folder 8, described valve body 1 one end is provided with the circular cylindrical cavity of mounting spring 2 and spool 3, the internal diameter of the other end is provided with taper hole and coordinates with the centrum section on valve gap 4, coordinate with the circular groove on valve gap 4 with O RunddichtringO 26 sealing, external diameter, seal with O RunddichtringO 1; Described fast folder 8 of inserting is inserted in the groove on valve body 1 by the through hole on valve gap 4, valve body 1 and valve gap 4 is fixed as one.
One end of described spring 2 is fixed on valve body 1, and the other end presses end (opening state) that spool 3 withstands on valve gap 4 center straight hole section and opens spool 3 and allow medium pass through or the end (closed condition) that withstands on valve body 1 circular cylindrical cavity is closed spool 3 and sealed and do not allow medium pass through.
The center straight hole section of described valve gap 4 one end is provided with notch 9, allows medium by entering bonnet central inner chamber in opening state; The other end is provided with hose connector 7, in order to cushion the axial relative movement (when opening or close) of valve body 1 and valve gap 4.
The described fast U-shaped plugging in folder 8 dehisces there is certain elasticity, and its distance L is slightly less than the outer diameter D of valve body 1 upper groove.
During work, medium flows into from valve body 1 end, and valve gap 4 end flows out.Opening state, each component connect in a manner described, the end of valve gap 4 center straight hole section is backed down spool 3 and is allowed medium to pass through (normal working), need to blind off a line once meet accident, extract fast plug in folder 8, the end that spool 3 withstands on rapidly valve body 1 circular cylindrical cavity under spring 2 acts on seals and does not allow medium pass through, and can realize fast shut-off function.
