Description
Technical field
This utility model relates to the valve used in a kind of automatic production line, is specifically related to a kind of pneumatic angle pedestal valve。
Background technology
Angle pedestal valve, also referred to as Y-valve, is the one in valve, and it acts on the medium being to turn on or blocking in pipeline, mainly has of completely closed or fully opens two kinds of duties, being commonly used in automatic production line, such as the industry such as pharmacy, chemical industry。Existing angle pedestal valve is mainly made up of valve body, spool and cylinder, spool is connected directly between on the piston rod of cylinder, and angle pedestal valve is generally closed type structure, and cylinder adopts single-acting cylinder, in cylinder, one end is provided with spring, under normal circumstances, spring acts on and promotes spool and the valve seat laminating on valve body on cylinder piston, makes valve block, after cylinder activation source of the gas, overcoming the elastic force of spring, band movable valve plug is lifted off a seat, and makes valve open。Owing to the closing force of spool ensures by the active force of spring completely, when medium enters from valve seat one end, when pressure medium is more than the precompression of spring, spool does not have reverse self-locking function, and pressure medium easily makes valve opening, phenomenon out of control occurs。When medium enters from spool one end, elastic force and the pressure medium sum of spring need to be overcome when opening, when pressure medium is bigger, it is necessary to bigger opening force, it is necessary to adopting the cylinder that cylinder diameter is bigger, structure is bigger。
Utility model content
In order to overcome existing angle pedestal valve spool there is no reverse self-locking function, pressure medium easily makes valve opening, deficiency out of control occurs, this utility model provides a kind of pneumatic angle pedestal valve, this pneumatic angle pedestal valve is adopted convertible sphere core and is connected with cylinder piston rod by connecting rod, reverse self-locking can be formed when spool is closed, the active force that pressure medium is delivered on spring is less or does not have, valve opening will not be made when pressure medium is bigger to be maintained to the sealing property of spool, do not have out-of-control phenomenon。
The technical solution of the utility model is: a kind of pneumatic angle pedestal valve includes valve body, spool and cylinder, valve body is provided with valve seat, cylinder is single-acting cylinder, the spring making spool close it is provided with in cylinder, valve body is connected to valve gap, cylinder is fixed on valve gap, described valve gap inwall is fixed with gripper shoe, the side of described spool and gripper shoe are hinged, the outer middle side part articulated linkage of spool, the other end of connecting rod and the piston rod of cylinder are hinged, the piston rod of cylinder is flexible can be made spool upset closure valve seat or open, when spool is closed, the included angle A between connecting rod and the piston rod of cylinder is between 90 °～100 °。
The sealing surface of described spool is sphere, and the sealing surface of valve seat is taper seat。
Described gripper shoe is provided with bar hole, and spool is fixed with jointed shaft, jointed shaft can in bar hole play。
When described spool is closed, the included angle A between connecting rod and the piston rod of cylinder is 90 °。
This utility model has the advantages that owing to taking technique scheme, under normal conditions (source of the gas off-state), under the action of the spring, the piston rod of cylinder stretches out and passes through connecting rod and promotes spool upset, until spool and valve seat Guan Bi, now the included angle A between connecting rod and the piston rod of cylinder is between 90 °～100 °, medium act on pressure on spool cylinder piston rod to component less or do not have, spool can form reverse self-locking, the elastic force of spring is enough to make to keep between spool and valve seat certain pressure, make that there is between spool and valve seat good sealing property, even if pressure medium is relatively big without making valve opening, do not have out-of-control phenomenon。

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1～Fig. 2, a kind of pneumatic angle pedestal valve, including valve body 1, spool 2 and cylinder 3, valve body 1 is provided with valve seat 4, cylinder 3 is single-acting cylinder, the spring 5 making spool 2 close it is provided with in cylinder 3, valve body 1 is connected to valve gap 6, cylinder 3 is fixed on valve gap 6, described valve gap 6 inwall is fixed with gripper shoe 7, the side of described spool 2 and gripper shoe 7 are hinged, the outer middle side part articulated linkage 8 of spool 2, the piston rod of the other end of connecting rod 8 and cylinder 3 is hinged, the piston rod of cylinder 3 is flexible can be made spool 2 upset closure valve seat 4 or open, when spool 2 is closed, the included angle A between the piston rod of connecting rod 8 and cylinder 3 is between 90 °～100 °。Owing to taking technique scheme, under normal conditions (source of the gas off-state), under the effect of spring 5, the piston rod of cylinder 3 stretches out and passes through connecting rod 8 and promotes spool 2 to overturn, until spool 2 and valve seat 4 close, now the included angle A between the piston rod of connecting rod 8 and cylinder 3 is between 90 °～100 °, medium act on pressure on spool 2 cylinder 3 piston rod to component less or do not have, spool 2 can form reverse self-locking, the elastic force of spring 5 is enough to make to keep between spool 2 and valve seat 4 certain pressure, make to have between spool 2 and valve seat 4 good sealing property, even if pressure medium is relatively big without making valve opening, do not have out-of-control phenomenon。
The sealing surface of described spool 2 is sphere, and the sealing surface of valve seat 4 is taper seat。Spool 2 has better automatic centering, requires relatively low to assembly precision, it is simple to process and assemble。
Described gripper shoe 7 is provided with bar hole 9, and spool 2 is fixed with jointed shaft 10, jointed shaft 10 can in bar hole 9 play。Spool 2 has certain side-play amount, can make spool 2 automatic centering when Guan Bi, also allow for assembling simultaneously。
When described spool 2 is closed, the included angle A between connecting rod 8 and the piston rod of cylinder 3 is 90 °。The present embodiment is optimal way, and now, the component of pressure medium is zero at the piston rod component upwards of cylinder 3。
