Abstract
The utility model discloses a fluid cutoff device, which comprises a valve body, a seal cover, a lifting rod and a flashboard. A pull rod is arranged between the lifting rod and the flashboard; the flashboard is fixed on the pull rod; a pull rod seal assembly is arranged between the pull rod and the seal cover; and the internal space of the seal cover is enough to store the flashboard under an opening state. The surface of the pull rod of the fluid cutoff device adopting the technical scheme is smooth, and the sealability between the pull rod and the pull rod seal assembly is good, and thereby, the service life of the pull rod seal assembly is prolonged; the flashboard still can be stored in the fluid cutoff device after being opened, and thereby, the sealability is further ensured.
Description
Technical field
The utility model relates to a kind of pipeline control gear of conveyance fluid, relates in particular to a kind of fluid shut-off means.
Background technique
At present, the fluid shut-off means is widely used in the industrial production.Fluid shut-off means lifting arm of the prior art is directly fixedlyed connected with flashboard, because lifting arm is leading screw or rack structure, the rough sealing part abrasion that causes is serious, produces the spill and leakage phenomenon at lifting arm and sealing cover place after use a period of time.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the purpose of this utility model provide a kind of sealability reliably, the fluid shut-off means of spill and leakage, black box long service life not.
Technological scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is: a kind of fluid shut-off means, comprise valve body, sealing cover, lifting arm, flashboard, between described lifting arm and flashboard, pull bar is set, flashboard is fixed on the pull bar, the pull bar black box is set between pull bar and sealing cover, and the inner space of described sealing cover enough stores the flashboard under the opening state.
Between the compression face of described flashboard and valve body, Sealing is set, the suction surface of flashboard be provided with some to direction consistent downward on wedge-shaped blocks, the following wedge-shaped blocks with its corresponding matching is set on valve body.
Described flashboard end is set to the wedge shape edge of a knife.
Beneficial effect: 1, favorable sealing property between pull bar smooth surface and the pull bar black box, in the working life of having improved the pull bar black box, assurance fluid not spill and leakage goes out the fluid shut-off means; 2, flashboard is stored in the sealing cover after opening, and assurance fluid not spill and leakage goes out the fluid shut-off means; 3, the suction surface of flashboard is provided with the following wedge-shaped blocks that is provided with on wedge-shaped blocks and the valve body and cooperates and give the flashboard opposite force, more closely makes the sealability of fluid shut-off means reliable thereby flashboard is cooperated with Sealing between the valve body; 4, the flashboard end is set to edge of a knife shape, has the function of shearing to be convenient to flashboard for the medium that is deposited in the valve body bottom and closes the location, back, guaranteed sealability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of accompanying drawing 1;
Fig. 3 is the partial enlarged drawing of accompanying drawing 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained.
As shown in Figure 1, structural representation for the utility model fluid shut-off means, comprise valve body 1, sealing cover 2, lifting arm 4, flashboard 5, between described lifting arm 4 and flashboard 5, pull bar 3 is set, flashboard 5 is fixed on the pull bar 3, between pull bar 3 and sealing cover 2 pull bar black box 6 is set, the inner space of described sealing cover 2 enough stores the flashboard 5 under the opening state.Sealability is better between pull bar 3 smooth surfaces and the pull bar black box 6, and pull bar 3 to-and-fro motion are also fewer to the wearing and tearing of pull bar black box 6 in long-term the use.The inner space of sealing cover 2 enough stores the flashboard 5 under the opening state, and when the fluid shut-off means was opening state, flashboard 5 is retracted in the sealing cover 2 can not take fluid out of the fluid shut-off means.
As shown in Figures 2 and 3, between the compression face of described flashboard 5 and valve body 1, Sealing 7 is set, the suction surface of flashboard 5 be provided with four pairs of directions consistent downward on wedge-shaped blocks 9, the following wedge-shaped blocks 10 with its corresponding matching is set on valve body 1.When flashboard 5 cuts out, go up wedge-shaped blocks 9 and cooperate the opposite force that gives flashboard 5, make flashboard be adjacent to Sealing 7, guarantee not spill and leakage of fluid shut-off means with following wedge-shaped blocks 10.Described flashboard 5 ends are set to edge of a knife shape 8, have the function of shearing to be convenient to flashboard 5 for the medium that is deposited in the valve body bottom and close the location, back, guaranteed sealability.
Claims (3)
1. fluid shut-off means, comprise valve body (1), sealing cover (2), lifting arm (4), flashboard (5), it is characterized in that: between described lifting arm (4) and flashboard (5), pull bar (3) is set, flashboard (5) is fixed on the pull bar (3), between pull bar (3) and sealing cover (2) pull bar black box (6) is set, the inner space of described sealing cover (2) enough stores the flashboard (5) under the opening state.
2. fluid shut-off means according to claim 1, it is characterized in that: between the compression face of described flashboard (5) and valve body (1), Sealing (7) is set, suction surface at flashboard (5) is provided with the consistent downward last wedge-shaped blocks (9) of some directions, goes up the following wedge-shaped blocks (10) that is provided with its corresponding matching at valve body (1).
