Abstract

The utility model provides a parallel hinge type double-flashboard sluice valve, which is mainly composed of a valve body, a valve rod, a main flashboard, and a subsidiary flashboard, wherein, the main flashboard is connected with the valve rod through a T-shaped buckle; the main flashboard and the subsidiary flashboard are longitudinally parallel and arranged in a staggered way; the main flashboard and the subsidiary flashboard are connected with a pin shaft through hinge link rods; slide slots are arranged on the main flashboard and the subsidiary flashboard; the hinge link rods are arranged in the slide slots. The utility model avoids the leakage phenomenon of a valve, has the advantages of easy manufacturing and flexible operation, can not cause a sealing surface to be damaged in use, and extends the service life of the valve.

Description

Parallel hinges formula double-flashboard gate valve

The utility model relates to a kind of valve, particularly is suitable for the parallel hinges formula double-flashboard gate valve that uses on the fluid pipe-line.

Along with the fast development of oil, chemical industry, more and more higher to the requirement of valve mass, the especially interior leakage problem of the seepage of valve more and more causes the attention of valve manufacturing firm.Existing valve is because the deficiency of its structure, easy to leak during its low pressure, and valve body sealing surface easily was scratched and damages when high pressure opened and closed, and influenced its working life, and this has not only wasted great amount of manpower and financial resources, and relates to people's life safety.

The purpose of this utility model is to provide a kind of parallel hinges formula double-flashboard gate valve of stopping seepage, increasing the service life, to overcome the deficiencies in the prior art part.

For achieving the above object, technical solution of the present utility model is: it mainly is made up of valve body, valve rod and major and minor flashboard; Main gate-board links to each other with valve rod by T shape button, and major and minor flashboard is parallel longitudinal, the setting of staggering, and major and minor flashboard links to each other with bearing pin by hinge linkage.

Be provided with chute on major and minor flashboard, hinge linkage is placed in one.

The utility model has been stopped the existing phenomenon of seepage of valve, and easy processing, and flexible operation does not cause sealing surface impaired during use, prolonged the working life of valve.

Description of drawings:

Fig. 1 is the utility model embodiment's a structural representation.

Below in conjunction with accompanying drawing the utility model and embodiment are described in further detail:

The utility model mainly is made up of valve body 10, valve rod 1 and major and

minor flashboard

4,5; Main gate-board 4 buckles 2 by the button of the T shape on it 3 with the inverted T-shaped of valve rod 1 end and links to each other, and major and

minor lock

4,5 plates are parallel longitudinal, the setting of staggering; Two at major and

minor flashboard

4,5 respectively are provided with two groups of chutes 6,9, and major and

minor flashboard

4,5 links to each other with eight bearing pins 8 by four hinge linkages 7, and hinge linkage 7 can rotate around bearing pin 8, and hinge linkage 7 places in the chute 6,9.When hinge linkage 7 was horizontal, auxiliary gate-board 5 ends were following, and main gate-board 4 ends are last.

When throttle down, firmly handling valve rod 1 makes it descending, the main gate-board 4 that links to each other with valve rod 1 is descending thereupon, and it is descending to drive auxiliary gate-board 5, when auxiliary gate-board 5 comes downwards to valve body 10 intracavity bottoms, auxiliary gate-board 5 stops descending, and main gate-board 4 is owing to the downward active force continuation that is subjected to valve rod 1, descending slightly, make major and

minor flashboard

4,5 to the left and right the sealing surface of the valve body 10 of both sides fit, make the sealing surface of major and

minor flashboard

4,5 and valve body 10 reach good sealing effect, thereby stopped the leakage problems of valve.

When Open valve, firmly to handle valve rod 1 and make it up, main gate-board 4 moves up earlier, and auxiliary gate-board 5 is finished the breakdown action of valve also moving in the lump under the effect of hinge linkage 7.The moment of opening and closing valve is all very little, therefore, and flexible operation.And it is impaired that sealing surface is difficult for scratch, prolonged the working life of valve.
