Abstract

The invention discloses a wedge type dual-gate valve installed on a steam-water system pipeline of a thermal power or nuclear power unit. The wedge type dual-gate valve comprises a valve body (1), a valve base (2), a valve rod (3) and a valve clack component (4), wherein the valve clack component comprises a main valve clack (5), an auxiliary valve clack (6), gaskets (7), a universal top (8) and a universal nut (9); when the valve is switched off, the wedge angle between the main valve clack (5) and the auxiliary valve clack (6) can be automatically adjusted to guarantee that the main valve clack (5) and the auxiliary valve clack (6) can be completely matched with the sealing face of the valve seat (2), so that high airtightness is guaranteed. By increasing or reducing the number of the gaskets (7), the distance between the main valve clack (5) and the auxiliary valve clack (6) can be adjusted, so that the emptying phenomenon is avoided. Guiding ribs (11) are arranged on the two sides of the main valve clack (5) and embedded in guiding grooves (10) in the valve body (1), the valve rod (3) drives the valve clack component (4) to move along the guiding grooves (10), rotation of the valve rod (3) is prevented, and installation at any positions can be achieved.

Description

A kind of Wedge type double gate board gate valve
Technical field
The present invention relates to a kind of Wedge type double gate board gate valve, belong to thermoelectricity, nuclear power generating sets valve field.
Background technology
The Wedge type double gate board gate valve of prior art typically uses clamping ring to connect left and right flap, and clamping ring size is relatively big, causes valve volume Relatively big, valve is heavier；A left side described in utility model patent ZL200520079167.8 disc connecting structure for embedded double disc gate valve Flap is connected with embedded gear with right flap, but the distance between two flaps can not adjust, and left flap and right flap are processed relatively Complexity, after sealing surface wear easy " lower a heatable brick bed "；Two flap spacings of utility model patent ZL01206399.1 Wedge type double gate board gate valve Can not adjust, valve is easily generated " lower a heatable brick bed " phenomenon equally；The Wedge type double gate board gate valve without clamping ring of prior art, two flaps are equal Arranging guiding rib, guiding rib is big with valve body gathering sill gap, and owing to flap center of gravity is misaligned with fulcrum, valve is horizontally mounted i.e. pacifies When being contained in vertical pipeline, upper flap occurs one side to tilt to upwarp, and easily touches with valve seat generation card, produces the not tight phenomenon of valve closing.
Summary of the invention
It is an object of the invention to provide a kind of Wedge type double gate board gate valve, the sphere of jack and universal nut respectively with auxiliary flap Guide face contacts, the spigot surface of auxiliary flap can be taper seat or sphere, is provided with pad, makes two between main valve clack and jack The angle of wedge between flap and distance adjustable, improve product hermeticity energy, only main valve clack and arrange guiding rib, and the center of gravity of auxiliary flap Overlapping with the fulcrum of jack, when valve is arranged on vertical pipeline, flap run-off the straight will not upwarp phenomenon, and valve closing is smooth and easy.
The technical scheme is that a kind of Wedge type double gate board gate valve, it includes valve body, valve seat, valve rod and flap assembly；Flap Assembly includes main valve clack, auxiliary flap, pad, jack, universal nut, and valve seat is welded to connect with valve body, on auxiliary flap Having spigot surface, valve body lumen both sides to be provided with gathering sill, main valve clack both sides are provided with guiding rib, and guiding rib embeds in gathering sill, valve rod It is connected by T-slot with main valve clack, drives flap assembly to move along gathering sill.
The sphere of described a kind of Wedge type double gate board gate valve jack and universal nut respectively with auxiliary flap guide face contacts, auxiliary The spigot surface of flap can be taper seat or sphere, makes angle of wedge adjustable between main valve clack and auxiliary flap, when the valve is closed, main Between flap and auxiliary flap, angle is coincide with valve seat, makes main valve clack, auxiliary flap fit completely with sealing surface of seat, improves valve Sealing property.
Being provided with pad between the main valve clack of described a kind of Wedge type double gate board gate valve and jack, the quantity of pad can be increased or decreased, Adjust main valve clack and auxiliary valve flap seal distance between the surface, it is to avoid occur after sealing surface wear that flap " lower a heatable brick bed " or valve fit badly existing As, make valve function lose efficacy.
Described a kind of Wedge type double gate board gate valve, auxiliary flap is without guiding rib, and only main valve clack guiding rib guides with valve body gathering sill, no Affected by flap assembly gravity, in addition to meeting right angle setting, also can realize being horizontally mounted, optional position can be realized and install.
The invention has the beneficial effects as follows: make angle of wedge adjustable between main valve clack and auxiliary flap by jack, make main valve clack and auxiliary Flap coincide with the valve base chamber angle of wedge, it is ensured that valve reaches good sealing；By increase and decrease pad adjustable main valve clack and auxiliary valve Flap seal distance between the surface, it is to avoid occur that " lower a heatable brick bed " or valve fit badly phenomenon, cause valve function to lose efficacy；Only main valve clack is arranged Guiding rib, can realize optional position and install.

Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
As shown in Fig. 1～Fig. 6, the present invention relates to a kind of Wedge type double gate board gate valve, including valve body (1), valve seat (2), valve rod (3) and flap assembly (4), flap assembly (4) includes main valve clack (5), auxiliary flap (6), pad (7), jack (8), universal nut (9), valve seat (2) is welded to connect with valve body (1), and main valve clack (5) and universal nut (9) use Threaded, valve rod (3) and main valve clack (5) are connected by T-slot (12), and drive flap assembly (4) is along gathering sill (10) Mobile, prevent valve rod from rotating.
