Abstract
The utility model discloses an intercepting valve structure with an elastic gasbag. The intercepting valve structure comprises a valve body, wherein a valve inlet is communicated with the upper part of one side of the valve body; a valve outlet is communicated with the bottom of the valve body; a clapboard is arranged in the middle of the valve body; a valve cover is mounted at the top of the valve body; a hollow valve rod is vertically mounted in the center of the valve cover in a sliding way; the upper part of the valve rod stretches out of the valve cover; the lower part of the valve rod stretches into the valve body and a choke plug is fixed to the lower part of the valve rod; the bottom end of the valve rod stretches out of the bottom of the choke plug; a lower support plate is connected to the bottom end of the valve rod; the elastic gasbag also sleeves the valve rod between the bottom of the choke plug and the top of the lower support plate; a gas port is communicated with the side wall of the upper part of the valve rod; a gas hole is formed in the side wall of the valve rod between the bottom of the choke plug and the top of the lower support plate. The intercepting valve structure with the elastic gasbag has a better sealing effect, and the intercepting capacity of the intercepting valve is improved.
Description
Technical field
The utility model relates to block valve field, is specially a kind of block valve structure with elastic bag.
Background technique
Block valve claims again cut-off valve, is widely used in pipeline in flowing medium transmission, and its effect is the flowing medium that blocks or connect in pipeline.The block valve of prior art exists sealing poor, blocks problem limited in one's ability, cannot meet flowing medium transmission demand.
Model utility content
The purpose of this utility model is to provide a kind of block valve structure with elastic bag, blocks the problem of ability to solve prior art block valve.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of block valve structure with elastic bag, include valve body, valve body one upper lateral part is communicated with into valve port, valve body bottom is communicated with out valve port, it is characterized in that: in the middle of described valve body, be provided with the dividing plate vertically separating in valve body, on having in connection valve body in the middle of dividing plate, the valve opening of bottom, described valve body top is provided with valve gap, valve gap center is vertically slidably fitted with the valve rod of the sensing dividing plate valve opening of hollow, stretch out from valve gap on described valve rod top, stem lower portion stretches in valve body and is fixed with the plug that can block up in dividing plate valve opening, and valve rod bottom passes from plug bottom, described valve rod bottom is connected with lower supporting plate, valve rod between plug bottom and lower supporting plate top also overlaps flexible air bag outward, described valve rod upper portion side wall is communicated with gas port, plug bottom is provided with and the pore being communicated with in elastic bag with the valve rod sidewall between lower supporting plate top.
Described a kind of block valve structure with elastic bag, is characterized in that: in described valve opening, be also provided with stuffing box gland.
In the utility model, flowing medium enters valve body from entering valve port, again by flowing out from going out valve port after valve opening on dividing plate, while blocking, by valve rod, plug is blocked up in valve opening, then by valve rod, in elastic bag, ventilate, elastic bag is extended to dividing plate bottom, body wall and combine closely, thereby further realize sealing.The utlity model has good sealing effect, improved the ability of blocking of block valve.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.A kind of block valve structure with elastic bag, include valve body 1, valve body 1 one upper lateral parts are communicated with into valve port 2, valve body 1 bottom is communicated with out valve port 3, in the middle of valve body 1, be provided with the interior dividing plate vertically separating 4 of valve body 1, in the middle of dividing plate 4, have be communicated with valve body 1 interior on, the valve opening of bottom, valve body 1 top is provided with valve gap 5, valve gap 5 centers are vertically slidably fitted with the valve rod 6 of sensing dividing plate 4 valve openings of hollow, stretch out from valve gap 5 on valve rod 6 tops, valve rod 6 bottoms are stretched in valve body 1 and are fixed with the plug 7 that can block up in dividing plate 4 valve openings, and valve rod 6 bottoms pass from plug 7 bottoms, valve rod 6 bottoms are connected with lower supporting plate 8, outside valve rod 6 between plug 7 bottoms and lower supporting plate 8 tops, also overlap flexible air bag 9, valve rod 6 upper portion side wall are communicated with gas port 10, plug 7 bottoms are provided with and the interior pore being communicated with 11 of elastic bag 9 with valve rod 6 sidewalls between lower supporting plate 8 tops.In valve opening, be also provided with stuffing box gland 12.
Claims (2)
1. the block valve structure with elastic bag, include valve body, valve body one upper lateral part is communicated with into valve port, valve body bottom is communicated with out valve port, it is characterized in that: in the middle of described valve body, be provided with the dividing plate vertically separating in valve body, on having in connection valve body in the middle of dividing plate, the valve opening of bottom, described valve body top is provided with valve gap, valve gap center is vertically slidably fitted with the valve rod of the sensing dividing plate valve opening of hollow, stretch out from valve gap on described valve rod top, stem lower portion stretches in valve body and is fixed with the plug that can block up in dividing plate valve opening, and valve rod bottom passes from plug bottom, described valve rod bottom is connected with lower supporting plate, valve rod between plug bottom and lower supporting plate top also overlaps flexible air bag outward, described valve rod upper portion side wall is communicated with gas port, plug bottom is provided with and the pore being communicated with in elastic bag with the valve rod sidewall between lower supporting plate top.
