Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model as Figure 1-4, the two exchange valves of a kind of list, comprise valve core 1, valve core rod 2, spring 3, valve core 1 intermediate portion has projection to the inside, there is outside projection at valve core rod 2 middle parts, spring 3 is arranged on the left end of valve core rod 2 intermediate projections, valve core rod 2 is arranged in valve core 1, the inner side of valve core 1 is close in one end of spring 3, spring 3 is when stretching, the right-hand member of valve core rod 2 intermediate projections is close in the projection of valve core 1, the left end of valve core 1 is fluid output 6, the right-hand member of valve core rod 2 is provided with valve core rod head air flue 11, it is characterized in that: the right-hand member of valve core 1 is flexibly connected cartridge cover bung flange 4, the inner side connection valve core cap 8 of cartridge cover bung flange 4, cartridge cover 8 is close to the right-hand member of valve core rod 2.According to the two exchange valves of described list, it is characterized in that: described cartridge cover bung flange 4 is the integral body being fixedly connected with cartridge cover 8.According to the two exchange valves of described list, it is characterized in that: described cartridge cover bung flange 4 and cartridge cover 8 two-part for separating, there is projection the right part of cartridge cover bung flange 4, and the right-hand member of cartridge cover 8 has projection, and the projection of cartridge cover bung flange 4 is close to mutually with the projection of cartridge cover 8.According to the two exchange valves of described list, it is characterized in that: described valve core 1 right-hand member outside is provided with outside thread, and cartridge cover bung flange 4 inner sides are provided with internal thread, valve core 1 and cartridge cover bung flange 4 bolts.According to the two exchange valves of described list, it is characterized in that: described valve core rod 2 intermediate projections are provided with valve core rod seal ring 10.According to the two exchange valves of described list, it is characterized in that: the projection of described valve core 1 is provided with valve core seal ring 9.According to the two exchange valves of described list, it is characterized in that: described cartridge cover 8 is for conical.According to the two exchange valves of described list, it is characterized in that: described cartridge cover 8 is that ladder is cylindrical.According to the two exchange valves of described list, it is characterized in that: the boss left end of described cartridge cover 8 is provided with cartridge cover seal ring 12.
Embodiment's 1 principle of the present utility model as Figure 1-4, when the unidirectional use of needs, cartridge cover bung flange 4 and cartridge cover 8 do not need to be spirally connected, liquid or gas flow into from fluid output 6, from valve core rod head air flue 11, flow out, the right-hand member of valve core rod 2 intermediate projections is close in the projection of valve core 1, can guarantee like this one-way flow of fluid, can only to right-hand member, flow by the left end from Fig. 1.When needs flow to left end from right-hand member, as long as install cartridge cover bung flange 4 and cartridge cover 8, cartridge cover bung flange 4 is spirally connected toward left side, cartridge cover 8 also moves to the left like this, cartridge cover 8 drives valve core rod 2 to move to the left, the right-hand member of valve core rod 2 intermediate projections and the projection of valve core 1 have just been separated from each other like this, and liquid or gas just can flow out from left side from middle space.When cartridge cover bung flange 4 is when spiral shell is moving to the right, due to the restoring force effect of spring 3, the right-hand member of valve core rod 2 intermediate projections is close to again in the projection of valve core 1.It is two-way that the utility model can make the one-way valve in pipeline become at any time, and the two-way one-way valve that becomes at any time regulates at any time, and seal is better, easy to use, simple to operate.
