Abstract
The utility model relates to a shunt reversing valve. The shunt reversing valve comprises a valve body with an inlet and two outlets, a valve rod arranged in a valve chamber of the valve body in a rotation manner, and a valve cap fixed on the valve rod and matched with two outlets. The shunt reversing valve is characterized in that the valve chamber wall of the valve body from the inlet to the outlets adopts a revolution surface taking the valve rod as a center; and the cross section of the arc-shaped curved surface is matched with the valve cap in shape. The valve chamber wall of the valve body from the inlet to the outlets adopts the revolution surface taking the valve rod as a center, and the cross section of the revolution surface is matched with the valve cap in shape, therefore, the shape of the valve chamber is just identical to that of movable space of the valve cap in the valve chamber, the volume of the valve chamber is reduced as much as possible, the volume of the entire shunt reversing valve body is further reduced, the materials of the valve body are reduced, and the manufacturing cost is reduced; moreover, the weight of the entire reversing valve is lessened, so that the processing is more convenient.
Description
Technical field
The utility model relates to a kind of valve, more particularly, relates to a kind of shunting selector valve that is applied in the high temperature fluid.
Background technique
In the prior art, traditional valve generally includes valve body, valve gap and rotatingshaft, comprises suction port and air outlet on the valve body, and rotatingshaft is installed in the rotation hole of valve gap, and rotatingshaft rotates the opening and closing that can realize valve body.But this valve body should not use for the high-temperature gas that the pressure drop requirement is arranged, and first pressure drop of flow is big, and the energy loss of gas is bigger when flowing, and it two is that the valve of good seal performance can not be used for hot environment at present.
When commutating control, adopt the high-temperature ball valve of metal hard-sealing usually for high-temperature gas.When needs commutate to high-temperature gas, adopt following tracheae linkage structure usually, promptly utilize a three-way pipe that gas is divided into two branch roads, on two branch roads, resistant to elevated temperatures ball valve is set respectively; By controlling the spool of two ball valves respectively, realize control to each tracheae branch road flow.But there is big resistance in this design for the gas that flows in pipeline, make gas energy loss when mobile very big, causes pressure drop big; Complex structure, the manufacture cost height.
For this reason, the applicant discloses a kind of high-temperature gas changing-over valve in Chinese patent application CN200810066723.6, and the applying date is on April 17th, 2008.This selector valve comprises valve body, valve rod and two valve gaps that are provided with a suction port and two relief openings, and valve gap can seal up two relief openings respectively when rotating in valve body with valve rod, thereby uses a valve just can commutate to high-temperature gas.Because valve gap need rotate in the valve pocket of valve body, therefore, need be provided with has enough big space in the valve pocket, this makes valve volume become bigger, more heavy, need more material to make, cost increases, and heavier part blank becomes very inconvenient man-hour adding.
The model utility content
The technical problems to be solved in the utility model is, the volume that exists at shunting selector valve in the prior art is big, heavy and cause processing inconvenience, cost problem of higher, and the shunting that a kind of volume is littler, cost is lower selector valve is provided.
The technological scheme that its technical problem that solves the utility model adopts is: construct a kind of shunting selector valve, comprise that valve body, rotation with an import and two outlets are arranged on the valve rod in the valve body valve pocket, be fixed on the valve rod and the valve gap that can cooperate with two outlets, it is the surface of revolution in the center of circle that valve cavity wall from import to outlet on the described valve body is set to the valve rod, and the sectional shape of this surface of revolution and described valve gap are complementary.
In shunting selector valve described in the utility model, described valve gap is set to circle, and the sectional shape of described surface of revolution is set to the circular arc that is complementary with described valve gap.
In shunting selector valve described in the utility model, the rotary middle spindle of described valve rod is arranged on the center line of described import, and vertical with the plane that intersects to form of center lines of described two outlets.
Implement shunting selector valve described in the utility model, have following beneficial effect: to be set to the valve rod is the surface of revolution in the center of circle by the valve cavity wall from import to outlet on the valve body, and the interface shape of this surface of revolution and described valve gap are complementary; Because valve gap is rotatable around valve rod in valve pocket, to realize commutation; This makes that the shape of valve pocket is just in time identical with the activity space of valve gap in valve pocket, thereby has dwindled the volume of valve pocket as much as possible, and then has dwindled the volume of whole shunting change valve, has reduced the material of valve body, has reduced cost of production; And alleviated the weight of whole selector valve, made processing become more convenient.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the structural representation of shunting selector valve described in the utility model.
Embodiment
As shown in Figure 1, in the preferred embodiment of shunting selector valve described in the utility model, comprise valve body 10, valve rod 20, valve gap 30.Wherein, valve body 10 is provided with an import 11 and two outlets 12a, 12b, and valve body 10 inside are set to the valve pocket 13 of hollow, and valve rod 20 rotations are arranged on the valve body 10 and stretch in valve pocket 13, and valve gap 30 is arranged in the valve pocket 13 and is fixed on the valve rod 20.When actuate valve stem 20 was rotated, valve rod 20 drove valve gap 30 and rotates in valve pocket 13, is sealed and matched respectively at different outlet 12a (or 12b), realizes the commutation of shunting selector valve.Preferably the rotary middle spindle A with valve rod is arranged on the centre line L 1 of import, and the plane that intersects to form with two outlet centre line L 2, L3 is vertical.
As shown in Figure 1, in this preferred embodiment, it is the surface of revolution P1 in the center of circle that the valve cavity wall P1 from import to outlet on the valve body 10 is set to the valve rod, and sectional shape and the described valve gap 30 of this surface of revolution P1 are complementary.Valve gap 30 preferably is set is and outlet 12 circles that are complementary, then the sectional shape of surface of revolution P1 also is set to the circular arc that is complementary with valve gap 30, and promptly the valve cavity wall P1 from import to outlet is bus, is the surface of revolution of track with the circular arc of the center of circle on valve rod central shaft A with the circular arc that is complementary with valve gap.Extremely valve cavity wall P1, the P2 of outlet all as above are set to surface of revolution with import, make in this shunting selector valve, in valve pocket 13, just there are enough spaces to rotate for valve gap 30, thereby dwindled the size of valve pocket, reduce valve volume, reduce cost, and reduce the weight of whole shunting selector valve, make that processing is more convenient.
The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
