Description
Technical field
This utility model relates to valve field, particularly relates to a kind of roller type gate valve.
Background technology
As illustrated in fig. 1 and 2, the gate valve of prior art includes valve body 1 ', the valve rod 2 ' being arranged on valve body and is arranged on valve rod 2 ' and rotates and the flashboard 3 ' of movement with valve rod 2 '.The internal both sides of described valve body 1 ' are arranged with gathering sill 4 '；It is convexly equipped with guiding rib 5 ' in described each gathering sill 4 '.Described flashboard 3 ' both sides are arranged with the stopper slot 6 ' coordinated with guiding rib 5 '.Described flashboard 3 ' coordinates with gathering sill 4 ' movable sealing.When gate valve uses vertical installation, rotation valve rod 2 ', flashboard 3 ' does vertical direction and moves, valve is in opening-closing process, flashboard 3 ' is mobile along the guiding rib 5 ' of valve body 1 ', during to ensure that flashboard is at an arbitrary position, the symmetrical center line in ram seal face is in alignment with valve rod axis, makes the abrasion of sealing surface be reduced to end degree.As shown in Figure 3, when gate valve uses horizontal installation, because between valve rod and flashboard being matched in clearance, valve rod is again to be coordinated by screw pair with flashboard, the impact conducted oneself with dignity due to flashboard 3 ' makes the stopper slot of flashboard contact with valve body guiding rib, and when valve opening and closing, the stopper slot of flashboard and valve body guiding rib are collided and can be produced the biggest frictional force, cause gate valve moment of torsion to increase, even cannot open and close.
In consideration of it, be necessary to design a kind of roller type gate valve to solve the problems referred to above.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of simple in construction and roller type gate valve convenient to operation.
For reaching above-mentioned purpose, this utility model provides following technical scheme: a kind of roller type gate valve, the valve rod including valve body, inserting valve inner and the flashboard being arranged on valve rod, described valve inner both sides are arranged with the gathering sill moved for flashboard, described flashboard coordinates with described gathering sill movable sealing, the both sides of described flashboard are arranged with the race corresponding with each gathering sill, the roller that can roll in gathering sill is installed in described each race, described roller is provided with annular spacing groove, is convexly equipped with and coordinates guiding rib with stopper slot inside described each gathering sill.
Further, a side surface of described flashboard is arranged with mounting groove, and described flashboard is provided with and is inserted and run through the bearing pin of described race by mounting groove and be positioned in mounting groove and the square plug fixing with bearing pin, and described roller is arranged on bearing pin.
Further, it is additionally provided with bearing between described bearing pin and roller.
Further, described roller type gate valve also includes that the valve gap coordinated with valve body, described valve rod one end are fixed on valve gap；The other end of described valve rod be provided with can along with the rotation of valve rod the flashboard hangers of movement, described flashboard is arranged on valve rod by flashboard hangers.
Further, described valve rod is horizontally disposed with, and described flashboard moves horizontally along valve rod, and said two roller lays respectively at the both sides up and down of flashboard.
Further, described flashboard is circular, and said two roller is positioned at the diametrically two ends of flashboard and the center of circle about flashboard is symmetrical.
Prior art is compared, and this utility model at least has the advantage that by installing roller on flashboard, not only contributes to the horizontal installation of gate valve and then adds the scope of application of gate valve, also reducing the open and close torque of gate valve；By coordinating of the stopper slot on roller and the guiding rib on valve body, not only ensure that the sealing property of gate valve, also improve the keying speed of gate valve.

Detailed description of the invention
Structure and the utility model content of roller type gate valve of the present utility model are described below in conjunction with Fig. 4 to 6.
A kind of roller type gate valve, can vertical installation can also horizontal install, it includes valve gap 2 that valve body 1 coordinates with valve body 1, is arranged on valve gap 2 and inserts the flashboard hangers 4 that the valve rod 3 within valve body 1 coordinates with valve rod 3 and the flashboard 5 being arranged on flashboard hangers 4.This utility model introduces horizontally-mounted roller type gate valve.
Described valve body 1 becomes the U-shaped of horizontal positioned, and its internal both sides up and down are arranged with the gathering sill 6 moved for flashboard 5.Described each gathering sill 6 is internal is convexly equipped with guiding rib 7.
Described valve rod 3 is horizontally disposed with, and its one end is fixed on valve gap 2；The flashboard hangers 4 that the other end is installed can the movement along with the rotation of valve rod 3.Described flashboard hangers 4 uses screw pair to coordinate with valve rod 3.
Described flashboard 5 is circular, and its upper and lower both sides are resisted against on the notch of gathering sill 6, i.e. forms movable sealing with described gathering sill 6 and coordinates.The both sides up and down of described flashboard 5 are arranged with the race 8 corresponding with each gathering sill 6.The roller 9 that can roll in gathering sill 6 is installed in described each race 8.Described roller 9 is provided with annular spacing groove 10.Described guiding rib 7 inserts in stopper slot 10.One side surface of described flashboard 5 is arranged with mounting groove 11.Described flashboard 5 is provided with the bearing pin 12 being inserted and running through described race 8 by mounting groove 11 and the square plug 13 being positioned in mounting groove 11 and fixing with bearing pin 12.Described roller 9 is arranged on bearing pin 8.It is additionally provided with bearing 14 between described bearing pin 8 and roller 9.Said two roller 9 is positioned at the diametrically two ends of flashboard 5 and the center of circle about flashboard 5 is symmetrical.
When gate valve is in opening-closing process, the roller 9 of flashboard is along guiding rib 7 horizontal rolling of valve body, the frictional force between the stopper slot 10 of roller and the guiding rib 7 of valve body is made to be transformed into force of rolling friction by force of sliding friction owing to roller 9 being combined with bearing 14, greatly reduce frictional resistance, open and close freely during gate valve work.
In sum, these are only preferred embodiment of the present utility model, scope of the present utility model should not limited with this.The most every simple equivalence change made according to this utility model claims and description with modify, all should still belong in the range of this utility model patent contains.
