Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model.

As shown in Figures 1 to 6, a kind of two-way valve, including valve body, valve body includes outer valve 1 and inner valve body 2, outer valve 1 and be equipped with the runner 8 for fluid flowing in inner valve body 2.Inner valve body 2 is threadedly secured in outer valve 1, is provided with spacing ring 11 in outer valve 1, and the end face that spacing ring 11 and inner valve body 2 are in outer valve 1 cooperatively forms placed cavity, is placed with sealing member 4 and core 5 in placed cavity, is provided with the runner 8 of circle in core 5.Rotating core 5 when needing to open this ball valve makes the circular flow channel 8 in core 5 connect outer valve 1 and the runner of inner valve body 2, rotates core 5 when needing to close this ball valve and makes the outer spherical wall of core 5 block the runner 8 between outer valve 1 and inner valve body 2.Outer valve 1 is made up of hexagonal rod, and profile is regular hexagon, convenient installation.It is provided with in inner valve body 2 and tightens hole 21 along what liquid flowed to, tighten hole 21 and overlap with the runner 8 in inner valve body 2, be positioned at the center of inner valve body, tighten hole 21 for regular hexagon, facilitate inner hexagon spanner to tighten inner valve body 2.Outer valve 1 one end is provided with inner valve body 2, and inner valve body 2 end is inside outer valve 1, and the other end stretches out outer valve 1, and inner valve body 2 stretches out one end processing of outer valve 1 external screw thread.Outer valve 1 other end is provided with female thread.

As shown in Fig. 2 and Fig. 7, Fig. 8, the processing of valve rod 6 top has flat position and forms placing trough, placing trough is provided with handle 3, is provided with the waist-shaped hole coordinated with flat position in handle 3, and handle 3 is provided above the nut for fixed handle 3.Handle 3 can be divided into connecting portion 31 and pulling part 32, and connecting portion 31 is rhombus, and the longer cornerwise end points place of rhombus is provided with downwardly convex limited block 7.The junction of connecting portion 31 and pulling part 32 is provided with arc reinforcement, and the opening of reinforcement is towards valve rod 6.The height of pulling part 32 is gradually increased from connecting portion 31 and pulling part 32 junction point to pulling part 32 end, so can increase the contact area of pulling part 32 and finger when pulling, more comfortable when making to pull.Pulling part 32 end is provided with the anti-drop block 322 preventing finger from skidding off from pulling part 32, it is prevented that finger slips from pulling part 32.

During assembling, first a sealing member 4 is put into outer valve 1 and conflicts with spacing ring 11, then valve rod 6 is loaded from outer valve 1 is internal and makes valve rod 6 head stretch out outer valve 1, then core 5 is loaded, and make it match with valve rod 6, then again second half sealing member 4 is loaded, then inner valve body 2 is screwed into outer valve 1 again and realizes the compression to sealing member 4 and core 5 and seal.Finally again handle 3 it is inserted on valve rod 6 and passes through nut screwing clamping, it is achieved overall assembling.

The above is only exemplary embodiment of the present utility model, and not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
