Abstract
The utility model relates to a gate valve disc with sealing washers. The gate valve disc comprises a disc body and two sealing washers, wherein the lower ends of the end faces on two sides of the disc body incline inwards. The gate valve disc with the sealing washers is characterized in that the sealing washers and the two end faces on two sides of the disc body are respectively welded for fixation. By means of the gate valve disc with the sealing washers, the sealing washers can be positioned well, and accordingly stable working performance of a gate valve can be ensured.
Description
Technical field
The utility model relates to valve field, particularly a kind of gate valve flashboard that carries seal washer.
Background technique
At present, existing gate valve has generally comprised valve body, and valve body is provided with medium flow channel, medium flow pass, valve pocket; Described valve pocket and medium flow channel, the equal conducting of medium flow pass are provided with valve rod, flashboard, seal washer in the valve pocket, described valve rod and flashboard are linked; The setting that slopes inwardly of the end face lower end, both sides of flashboard; Flashboard both sides end face is provided with positioning groove, and seal washer is obliquely installed in positioning groove, is gone up and down by valve rod control flashboard; When forming sealing between seal washer on flashboard and medium flow channel, the medium flow pass, gate valve is in cut-off state.
But, the gate valve flashboard of this structure, because seal washer relies on the positioning groove location, seal washer receives washing away of medium for a long time, is easy to generate looseningly, and then causes poor sealing performance between itself and the flashboard, gate valve cisco unity malfunction.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of gate valve flashboard that carries seal washer, and it can locate seal washer well, thereby can guarantee the stable work in work of gate valve.
The technological scheme of the utility model: a kind of gate valve flashboard that carries seal washer; Include flashboard body, two seal washers; The setting that slopes inwardly of the end face lower end, both sides of described flashboard body, it is characterized in that: the both sides end face of described two seal washers and flashboard body welds fixing respectively.
Adopt technique scheme, the both sides end face welding of described seal washer and flashboard body is fixing, easy to process, and can locate seal washer well, thus can guarantee the stable work in work of gate valve.
The further setting of the utility model: corresponding seal washer central hole location is provided with buffer cavity on the both sides end face of described flashboard body.
Adopt above-mentioned further setting, the buffer cavity of setting can reduce the impact of medium to the flashboard body, thereby has prolonged the working life of flashboard.
Further being provided with again of the utility model: described buffer cavity includes flat bottoms and buffering side; Wherein, The buffering side includes the first circular arc sidewall to flashboard body inside bend, to the second circular arc sidewall of flashboard body outside curve, to the three-arc sidewall of flashboard body inside bend; The described second circular arc sidewall two ends first circular arc sidewall, three-arc sidewall respectively connect; The first circular arc sidewall extends on the both sides end face of flashboard body with respect to it is connected an end with the second circular arc sidewall the other end, and the three-arc sidewall is connected with flat bottoms with the other end that the second circular arc sidewall is connected an end with respect to it.
Adopt above-mentioned further setting again; The first circular arc sidewall can make things convenient in the medium turnover buffer cavity, and the second circular arc sidewall can reduce the impact force of medium, and the three-arc sidewall can reduce the impact of medium to flat bottoms; The buffer cavity of this structure is simple in structure, good buffer effect.
