Abstract
The utility model discloses an automatically controlled bidirectional reversing valve, comprising a valve body; reversing ports are respectively formed in the top and the bottom of the valve body; seal rings are respectively arranged at the two reversing ports; a guide rod is connected between the top and the bottom of the valve body at the left side of the two reversing ports; the automatically controlled bidirectional reversing valve also comprises a lead screw and a pair of support seats; spherical plugs capable of being plugged into the sealing rings in the reversing ports are arranged on tops of the two support seats respectively; the bottom end of the lead screw is rotationally connected onto the bottom of the valve body; the upper part of the lead screw is rotationally arranged at and penetrates through the top of the valve body; the left sides of the two support seats are glidingly arranged on the guide rod; a connection pipe is connected between the right sides of the two support seats; internal threads are molded at the inner wall of the connection pipe; the lead screw penetrates through the connection pipe and is matched with the internal threads at the inner wall of the connection pipe. The flow speed of a medium cannot be influenced by the deviation generated by the automatically controlled bidirectional reversing valve, the rotation of the lead screw can be controlled by an external motor, and the automation control of the reversing valve is realized.
Description
Technical field
The utility model relates to selector valve field, is specially a kind of two-way selector valve that can automatically control.
Background technique
Selector valve is a kind of conventional valve class device, and its Main Function is the switching that realizes media flow direction, is widely used on media flow pipeline.In prior art selector valve, in adopt, have the commutation spheroid of cavity to rotate to realize commutation, the spheroid that in use commutates is subject to the impact of medium impact force and produces skew, thereby affects media flow speed more.
Model utility content
The purpose of this utility model is to provide a kind of two-way selector valve that can automatically control, to solve prior art selector valve utilization commutation spheroid, rotates the easy problem that produces bias effect media flow speed of commutation that realizes.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of two-way selector valve that can automatically control, the valve body that has horizontal cavity in comprising, valve body one end is connected with the inlet pipe mouth being communicated with horizontal cavity one end, it is characterized in that: valve body top, bottom has the commutation mouth being communicated with horizontal cavity, two commutations mouthful are respectively arranged with seal ring with horizontal cavity junction, the valve body top in two commutations mouthful left side, between bottom, be connected with guide rod, also include screw mandrel, and be arranged on a pair of supporting base being arranged above and below between two commutation mouths, wherein the supporting base top of top is provided with towards valve body top commutation mouthful and also can blocks up the spherical obstruction in top commutation mouth sealing ring, the supporting base bottom of below is provided with towards valve body bottom commutation mouth and can blocks up the spherical obstruction in bottom commutation mouth sealing ring, and between two supporting bases, spacing is less than the height of the horizontal cavity of valve body, described screw mandrel bottom is rotatably installed in the valve body bottom on two commutation mouth right sides, valve body top and screw mandrel top that screw mandrel top is rotatably installed in two commutation mouth right sides pass from valve body top, two supporting base left sides are slidably mounted on guide rod, between two supporting base right sides, be connected with connecting tube, connecting tube inwall forms internal thread, described screw mandrel passes and coordinates with connecting tube inner thread from connecting tube between two supporting bases.
The described a kind of two-way selector valve that can automatically control, is characterized in that: described screw mandrel and junction, valve body top are provided with stuffing box gland.
In the utility model, supporting base left side is slidably matched with guide rod, and supporting base right side connecting tube coordinates with wire rod thread, by rotary screw rod, can realize two supporting bases lower slider on the whole, thereby utilize spherical obstruction to block up in turn in commutation mouth, realize MEDIA FLOW to switching.The utility model can not produce bias effect velocity of medium, and can by external motor, control the rotation of screw mandrel, realizes the automation of selector valve and controls.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
