The utility model provides a sealed face is difficult to be destroyed to the two -way combination is from sealing gate valve who presses that gives just can bear, turn over. The utility model discloses a flashboard and disk seat, its characterized in that: the flashboard is provided with the dovetail with the corresponding department of disk seat, be provided with in the dovetail with dovetail interference fit's sealing washer, the contact surface of sealing washer and disk seat be provided with at least two rings sealed protruding, the upper and lower both sides of sealing washer be provided with with flashboard complex hook portion.
Description
Technical field
The utility model belongs to seal gate valve technical field, is specifically related to a kind of combination self-sealing gate valve.
Background technique
For many years, for the gate valve of slurry medium pipeline, as shown in Figure 3, what the sealing surface of its flashboard 4 adopted is a pressurize circle 7(material is rubber-like) and bracing ring 8(material be cemented carbide class) sealing, pressurize circle 7 and the contact of opposite valve seat 1 are the linear contact lay of sub-circular, if when sealing surface and medium contact, have particle to be clipped on this annular wire, sealing surface will be destroyed.And because the structure of pressurize circle 7 limit, there is requirement in its pressurized direction, if from oppositely giving pressure, 7, pressurize circle can not play seal action.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of sealing surface to be not easily destroyed, and can bear positive and negative two-way to the combination self-sealing gate valve of pressure.
In order to realize above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, and the utility model comprises flashboard and valve seat, it is characterized in that: flashboard and valve seat corresponding section are provided with dovetail groove; Be provided with the seal ring with dovetail groove interference fit in dovetail groove, the surface of contact of seal ring and valve seat is provided with at least two and encloses seal convexity; The both sides up and down of seal ring are provided with the hook portion coordinated with described flashboard.
As a kind of preferred version of the present utility model, the described flashboard whole surface corresponding with valve seat by described seal ring and hook portion coated.
As another kind of preferred version of the present utility model, described seal ring can adopt urethane rubber.
The beneficial effects of the utility model: 1, the utility model by arranging multiple seal convexity on seal ring, forms multiple-sealed annular wire, can avoid situation about damaging because sealing surface enters particulate matter to occur.
2, the whole surface of contact between the utility model flashboard and valve seat is all covered by seal ring, effectively can protect sealing surface, the function of pressurize circle and bracing ring is united two into one simultaneously, simplifies the structure, be convenient to production and processing and assembling.
3, the utility model adopts urethane rubber, and have good elasticity and lower friction factor, abrasion resistant effect is good.
4, the installation between seal ring of the present utility model and flashboard adopts the dovetail groove of interference to design, and can not leak pressure, also can not come off in action frequently, long service life.
5, the channel side of sealing surface of the present utility model or valve body side all can pressurizeds, and applicable is wider.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of seal ring.
Fig. 3 is the structural representation of valve seat and flashboard in prior art.
1 be valve seat, 2 be seal ring in accompanying drawing, 3 be dovetail groove, 4 be flashboard, 5 be hook portion, 6 be seal convexity, 7 be pressurize circle of the prior art, 8 for bracing ring of the prior art.
Embodiment
The utility model comprises flashboard 4 and valve seat 1, it is characterized in that: flashboard 4 and valve seat 1 corresponding section are provided with dovetail groove 3; Be provided with the seal ring 2 with dovetail groove 3 interference fit in dovetail groove 3, seal ring 2 is provided with at least two with the surface of contact of valve seat 1 and encloses seal convexity 6; The both sides up and down of seal ring 2 are provided with the hook portion 5 coordinated with described flashboard 4.
As a kind of preferred version of the present utility model, the described flashboard 4 whole surface corresponding with valve seat 1 by described seal ring 2 and hook portion 5 coated.
Described hook portion 5 is set to circular arc with surface, valve seat 1 contacting point; Be convenient to hook portion 5 and enter valve seat 1 scope.
As another kind of preferred version of the present utility model, described seal ring 2 can adopt urethane rubber.
Urethane rubber can adopt import high abrasion urethane rubber.
Described seal convexity 6 can be set to three or more.
Be understandable that, above about specific descriptions of the present utility model, the technological scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
