Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of simple to operate, maintenance cost is low and maintenance time is short and the control valve of the reliable two-position three way of working stability.
The purpose of this utility model is achieved through the following technical solutions: a kind of control valve of two-position three way, it comprises valve body, handle, upper valve rod, lower valve rod, gas-entered passageway, outlet passageway one and outlet passageway two, valve body is hollow structure, the bottom of valve body offers gas-entered passageway, upper valve rod and lower valve rod are arranged at valve inner, the bottom of upper valve rod and the top card of lower valve rod are combined, top and the handle of upper valve rod are fixedly linked, the bottom of lower valve rod offers suction port along axis, the middle part of lower valve rod radially offers air outlet, suction port is communicated with air outlet, the both sides of valve body are connected with outlet passageway two with outlet passageway one respectively, the inner side cooperation of outlet passageway one is provided with valve head A, the inner side cooperation of outlet passageway two is provided with valve head B.
Described outlet passageway one, outlet passageway two, valve head A, valve head B and air outlet coaxial line.
Described handle and upper valve rod are fixedly linked by fixing pin.
The top of described valve body is also provided with limiting stopper, and the bottom of limiting stopper and handle is connected.
The utlity model has following advantage:
1, by rotatable handle, upper valve rod drives the lower valve rod of engaging with it, and gas-entered passageway is communicated with outlet passageway, and it is simple in structure, easy to operate.
2, valve head A and valve head B are set respectively in gas-entered passageway and outlet passageway, valve head A and valve head B are coordinated with lower valve rod, after valve head A and valve head B wearing and tearing, only need to change left passage and right passage, maintenance cost is low, when changing, screw off gas-entered passageway and outlet passageway, take out valve head A and valve head B, can realize quick change, significantly shorten maintenance time.
3, left passage and right passage keep closely cooperating with lower valve rod constantly, its good seal performance, working stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-valve body, 2-handle, 3-gas-entered passageway, 4-outlet passageway one, 5-outlet passageway two, 6-valve head A, 7-valve head B, 8-upper valve rod, 9-lower valve rod, 10-suction port, 11-air outlet, 12-fixing pin, 13-limiting stopper.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of control valve of two-position three way, it comprises valve body 1, handle 2, upper valve rod 8, lower valve rod 9, gas-entered passageway 3, outlet passageway 1 and outlet passageway 25, valve body 1 is hollow structure, the bottom of valve body 1 offers gas-entered passageway 3, upper valve rod 8 and lower valve rod 9 are arranged at valve body 1 inside, the top card of the bottom of upper valve rod 8 and lower valve rod 9 is combined, the top of upper valve rod 8 and handle 2 are fixedly linked, the bottom of lower valve rod 9 offers suction port 10 along axis, the middle part of lower valve rod 9 radially offers air outlet 11, suction port 10 is communicated with air outlet 11, the both sides of valve body 1 are connected with outlet passageway 25 with outlet passageway 1 respectively, the inner side cooperation of outlet passageway 1 is provided with valve head A6, the inner side cooperation of outlet passageway 25 is provided with valve head B7.
