Abstract
The utility model relates to a hard sealing gate valve of elasticity. Present plate valve required precision sealed firmly higher, be not convenient for assembly and the higher problem of cost have mainly been solved. Its characterized in that: disk seat (3) formula structure as an organic whole, the one end of disk seat (3) is equipped with the cross -section for convex flexure strip (31), the outer wall of disk seat (3) is equipped with the cross -section for convex annular (32), flexure strip (31) stretch out the end for waiting wall thickness structure, the surface of flexure strip (31) is tangent with the hole of disk seat (3), inlay on valve body (1) through the tight fit disk seat (3). This hard sealing gate valve of elasticity adopts integral type elastic valve seat directly to inlay on the valve body, utilizes arc flexure strip automatic compensation flashboard and the clearance between the disk seat on the disk seat, and the required precision is low, is convenient for assemble, and is with low costs.
Description
Technical field
The utility model relates to a kind of hard sealed flat gate valve, is specifically related to a kind of elastic hard sealing gate valve.
Background technique
Plate valve belongs to stop valve class, and its effect is the medium connected or block in pipeline, mainly contains completely closed or opens two kinds of working staties completely.Sealability between flashboard and valve seat is the most important technical performance index of this kind of valve, is under normal circumstances not allow to produce to leak, and therefore often adopts hard sealing structure between flashboard and valve seat, namely adopts metallic sealing section between valve seat and valve plate.In order to reach good sealing effect, usually adopting sliding type valve seat, between valve seat and valve body, elastic component being installed, to compensate the sealing surface wear of valve seat or valve plate.There is following technological deficiency in existing hard sealed flat gate valve: due to valve seat energy valve body slides relatively, need to install elastic component, component are more, and during assembling, required precision is higher, be not easy to assembling, and cost are higher.
Model utility content
In order to overcome existing hard sealed flat gate valve required precision higher, be not easy to assemble and the higher deficiency of cost, the utility model provides a kind of elastic hard sealing gate valve, this elastic hard sealing gate valve adopts integrated elastic valve seat to be directly embedded on valve body, utilize the gap between arc elastic sheet auto-compensation flashboard on valve seat and valve seat, required precision is low, be convenient to assembling, cost is low.
The technical solution of the utility model is: a kind of elastic hard sealing gate valve comprises valve body and flashboard, in described valve body, valve seat is installed, described valve seat is integral type structure, one end of valve seat is provided with the spring sheet that cross section is circular arc, the outer wall of valve seat is provided with the annular groove that cross section is circular arc, the external part of spring sheet for waiting wall thickness structure, the outer surface of spring sheet and the endoporus of valve seat tangent; Valve seat is embedded on valve body by drive fit.
The outer surface of described spring sheet is provided with wear-resisting hard alloy layer.
Described flashboard is provided with flowing hole, and lower end and the flowing hole edge of flashboard are equipped with circular arc chamfering.
Described valve base inner wall is provided with handling groove.
The utility model has following beneficial effect: owing to taking technique scheme, spring sheet has certain elasticity, make the outer surface of spring sheet can keep with flashboard the state that fits all the time, realize the hard sealing between flashboard and valve seat, certain elasticity tension is there is after spring sheet is contracted, can gap between auto-compensation flashboard and valve seat, required precision is low, be convenient to assembling, cost is low.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 ~ Fig. 3, a kind of elastic hard sealing gate valve, comprise valve body 1 and flashboard 2, in described valve body 1, valve seat 3 is installed, described valve seat 3 is integral type structure, and one end of valve seat 3 is provided with the spring sheet 31 that cross section is circular arc, and the outer wall of valve seat 3 is provided with the annular groove 32 that cross section is circular arc, the external part of spring sheet 31 for waiting wall thickness structure, the outer surface of spring sheet 31 and the endoporus of valve seat 3 tangent; Valve seat 3 is embedded on valve body 1 by drive fit.Owing to taking technique scheme, spring sheet 31 has certain elasticity, make the outer surface of spring sheet 31 can keep with flashboard 2 state that fits all the time, realize the hard sealing between flashboard 2 and valve seat 1, certain elasticity tension is there is after spring sheet 31 is contracted, can gap between auto-compensation flashboard 2 and valve seat 3, required precision is low, be convenient to assembling, cost is low.
The outer surface of described spring sheet 31 is provided with wear-resisting hard alloy layer 33.Hard alloy layer 33 has wear-resisting, corrosion-resistant and oxidation resistance preferably.
Described flashboard 2 is provided with flowing hole 21, and lower end and flowing hole 21 edge of flashboard 2 are equipped with circular arc chamfering 22.When opening or close flashboard 2, spring sheet 31 slips over along circular arc chamfering 22, avoids stuck or causes damage to the outer surface of spring sheet 31.
Described valve seat 3 inwall is provided with handling groove 34.Utilize clamp instrument to block handling groove 34 to carry out assembling or dismantle valve seat 3.
Claims (4)
1. an elastic hard sealing gate valve, comprise valve body (1) and flashboard (2), in described valve body (1), valve seat (3) is installed, it is characterized in that: described valve seat (3) is integral type structure, one end of valve seat (3) is provided with the spring sheet (31) that cross section is circular arc, the outer wall of valve seat (3) is provided with the annular groove (32) that cross section is circular arc, the external part of spring sheet (31) for waiting wall thickness structure, the outer surface of spring sheet (31) and the endoporus of valve seat (3) tangent; Valve seat (3) is embedded on valve body (1) by drive fit.
