Description
Technical field
The utility model relates to a kind of metering valve, particularly a kind of multiple-way valve of automatic compensation sealing.
Background technique
Multiple-way valve is the valving that is widely used in the metering station measurement flow, and multiple-way valve can be realized automatically controlled well at the scene or pass through the handwheel direct control after being equipped with special-purpose electric control box.Multiple-way valve one cover can be realized the metering of tens pipeline media and collect defeated that effect is far superior to original three-way valve group.Original relatively artificial pressure control valve group has significantly reduced the workload of manual operation three-way valve group.Medium import and dip hatch that the multiple-way valve of prior art adopts the spool that has medium runner of rotation to connect and is arranged on the valve body are realized what rate-of flow measured; Other medium imports then are communicated with the collection outlet by the cavity in the valve body, realize what medium transported.When being communicated with between the medium import on the medium runner of the multiple-way valve spool of this kind structure inlet and the valve body, the engaged at end place needs sealing, existing multiple-way valve fits tightly by both ends of the surface and seals, after repeatedly rotary manipulation rubs, the sealing surface rapid wearing, make the metering medium flow into valve cavity and enter the collection outlet, cause the metering result inaccurate.Medium runner in the existing multiple-way valve spool adopts right angle channel, and fluid resistance is bigger, and the pressure head resistance is bigger, improves the runner internal pressure, and conveyance capacity reduces, and sealing effect is damaged.
Simultaneously, existing multiple-way valve adopts electronic control, and controller separates with Electric actuator, and wiring and maintenance workload are bigger, lost labor's cost.
Therefore, need a kind of multiple-way valve, can guarantee sealing effect, prolong the working life of multiple-way valve; Reduce medium at a spool runner internal pressure resistance, guarantee sealing effect, thereby guarantee metering result's accuracy.
The model utility content
In view of this, the purpose of this utility model provides a kind of multiple-way valve of automatic compensation sealing, can guarantee sealing effect, prolongs the working life of multiple-way valve; Reduce medium at a spool runner internal pressure resistance, guarantee sealing effect, thereby guarantee metering result's accuracy.
The multiple-way valve of automatic compensation sealing of the present utility model comprises valve body, valve gap, valve rod and spool, and described valve body is provided with two above medium imports, a collection outlet and a dip hatch; Described spool is fixedlyed connected with valve rod and is rotatably assorted with valve body; Spool is provided with medium runner, the end opening of described medium runner communicates with dip hatch, suitable for readingly under drive rotating, spool can communicate with arbitrary medium import, comprise that also Spielpassung is enclosed within the wall suitable for reading elastomer and the cirque body seal ring on every side of spool medium runner, described elastomer is provided with pretightening force, one end and spool relative fixed, the other end withstands seal ring, and the seal ring end face is near body cavity medium inlet end face.
Further, around the wall suitable for reading of the medium runner of described spool circular groove is set, described elastomer and seal ring are arranged in the circular groove;
Further, it is excessive that the medium runner of described spool adopts the circular arc obtuse angle;
Further, the drive unit of described valve rod is an Electric actuator, and the controller of described Electric actuator is arranged in the drive unit;
Further, described elastomer is a bellows springs;
Further, described elastomer is the stainless steel cylindrical spring.
The beneficial effects of the utility model are: the multiple-way valve of automatic compensation sealing of the present utility model, the medium inlet end face adopts the sealing configuration that elastomer and seal ring cooperate on spool runner end face suitable for reading and the valve body, by initial tension of spring, compress seal ring and realize sealing, wearing and tearing that can the automatic compensation sealing section, guarantee sealing effect, prolong the working life of multiple-way valve; Elastomer and seal ring are arranged in the circular groove around the wall suitable for reading of spool medium runner, guarantee the coaxality of seal ring and medium runner, are that sealing effect is better, make the seal ring end wear even, are beneficial to raising multiple-way valve working life; Medium runner adopts the circular arc obtuse angle excessive, reduces medium at a spool runner internal pressure resistance, avoids because pressure improves the destruction to sealing effect, thereby guarantees metering result's accuracy; Adopt bellows springs, make seal face stressed evenly, avoid heel and toe wear; The controller of Electric actuator is arranged in the drive unit, and cost of labor is saved in wiring and easy to maintenance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Accompanying drawing is a structural representation of the present utility model, and as shown in the figure: the multiple-way valve of present embodiment automatic compensation sealing is that manual drives and motivational drive combine, and drive unit 10 is an Electric actuator, and the controller 11 of Electric actuator is arranged in the drive unit 10.The utility model comprises valve body 1, valve rod 9 and spool 2, and valve body 1 is provided with 12 medium imports 7, a collection outlet 6 and a dip hatch 4; Spool 2 is fixedlyed connected with valve rod 9 and is rotatably assorted with valve body 1, seals between two ends and the valve body about the spool; Spool 2 is provided with medium runner 3, medium runner 3 adopts the circular arc obtuse angle excessive, the end opening of medium runner 3 communicates with dip hatch 4, suitable for readingly under spool 2 drives, rotate and to communicate with arbitrary medium import 7, comprise that also Spielpassung is enclosed within the cirque body seal ring 8 that stainless steel cylindrical spring 5 around the wall suitable for reading of medium runner 3 of spool 2 and metallo-plastic are made, around the wall suitable for reading of the medium runner 3 of spool 2 circular groove 12 is set, stainless steel spring 5 and seal ring 8 are arranged in the circular groove 12; Stainless steel spring 5 is provided with pretightening force, and an end fixes on circular groove 12 bottom lands and spool 2 relative fixed, and the other end withstands seal ring 8, and seal ring 8 end faces are near valve body 1 inner chamber medium import 7 end faces.
