Abstract

The utility model discloses a kind of ball check valve, belong to valve field.This ball check valve comprises valve body, valve gap and valve seat, and valve body is provided with the little throttling spheroid of entrance large outlet, and spheroid exit position is provided with non-return structure.It is more stable that the utility model aims to provide a kind of performance, the ball check valve that structure simply prevents medium from flowing backwards.

Description

Ball check valve
Technical field
The utility model belongs to valve field, is specifically related to a kind of ball check valve.
Technical background
Ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.Be provided with spheroid in ball valve, realize opening or closing the function of medium channel mainly through spinning ball, then can play cut-outs, distribute and the effect in change media flow direction, structure function is more single.
For preventing medium from flowing backwards, a usual safety check of connecting with ball valve in pipeline, does not have the independent ball valve that can play non-return effect in the prior art.
Model utility content
The utility model discloses a kind of ball check valve, aim to provide a kind of performance more stable, the ball check valve that structure simply prevents medium from flowing backwards.
For achieving the above object, the technical solution of the utility model is as follows:
Ball check valve, comprises valve seat bearing ring 9, valve gap 1, spheroid 10, it is characterized in that: be provided with non-return structure in spheroid exit position, comprises valve clack cover 7, flap 2, the axis of guide 5, guide collar 4, dunnage 3 and Boilor check valve seat 8; Described valve clack cover 7 is connected by screw with flap 2, is arranged on throttling spheroid 10 outlet port; Described Boilor check valve seat 8 is L-type, and its one end is arranged between valve clack cover 7 and flap 2, and the other end pushes against valve seat bearing ring 9.
Described dunnage 3 is arranged in valve gap 1, is provided with guide collar 4 and the axis of guide 5, is connected to flap 2 by the axis of guide 5 in the middle part of it.
Described guide collar 4 has spring eye, is provided with spring 6 in spring eye, and spring supports 6 on flap 2.
Described spheroid is the throttling spheroid 10 that entrance large outlet is little.
The beneficial effects of the utility model are:
One, the utility model structure is simple, and each component produce neither tired capsule, install easily in addition, are beneficial to and promote;
Two, spheroid adopts the throttling spheroid that entrance large outlet is little, directly limits the flow of medium, owing to forcing to be obstructed throttling, so the pressure difference before and after throttling is large, plays the effect of decompression;
Three, L-type Boilor check valve seat design, make it be fastened between flap and valve clack cover, its one end holds out against valve seat, plays good sealing effect, prevents medium from flowing backwards;
Four, be connected by the axis of guide between flap with dunnage, determine when medium circulates, flap moves can not produce skew to Way out, when returning to original position, not having displacement and causing Boilor check valve seat seal failure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 be valve gap, 2 be flap, 3 be dunnage, 4 be guide collar, 5 be the axis of guide, 6 be spring, 7 be valve clack cover, 8 be Boilor check valve seat, 9 be valve seat bearing ring, 10 be throttling spheroid, 11 for valve rod.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1, ball check valve, comprises valve seat bearing ring 9, valve gap 1, spheroid 10, it is characterized in that: be provided with non-return structure in spheroid exit position, comprises valve clack cover 7, flap 2, the axis of guide 5, guide collar 4, dunnage 3 and Boilor check valve seat 8; Described valve clack cover 7 is connected by screw with flap 2, is arranged on throttling spheroid 10 outlet port; Described Boilor check valve seat 8 is L-type, and its one end is arranged between valve clack cover 7 and flap 2, and the other end pushes against valve seat bearing ring 9.Described dunnage 3 is arranged in valve gap 1, is provided with guide collar 4 and the axis of guide 5, is connected to flap 2 by the axis of guide 5 in the middle part of it.Described guide collar 4 has spring eye, is provided with spring 6 in spring eye, and spring supports 6 on flap 2.Described spheroid is the throttling spheroid 10 that entrance large outlet is little.When ball valve works, flow into medium from entrance, by throttling spheroid 10, because of the structure characteristic that its entrance large outlet is little, directly limit the flow of medium, owing to forcing to be obstructed throttling, so the pressure difference before and after throttling is large, play the effect of decompression.Promote valve clack cover 7 when medium acts on valve clack cover 7 to move right along the axis of guide 5 with flap 2, Compress Spring 6, Boilor check valve seat 8 moves thereupon, seal failure, and medium circulates.Because of the position-limiting action of the axis of guide 5, flap moves right and can not produce downward shift, when returning to original position, not having displacement and causing Boilor check valve seat sealability to weaken.When medium stops flowing into, spring 6 bounce-back promotes flap 2 and resets, and Boilor check valve seat 8 continues to push against valve seat bearing ring 9, plays seal action, and medium can not be back in throttling spheroid.
