Description

Technical Field

[0001] The utility model relates to the technical field of two-way valves, in particular to a manually controlled two-way valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. They are also control components in fluid conveying systems. They have functions such as cutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Some devices on the market currently use one-way valves, which have only one passage and cannot be manually controlled, greatly affecting the efficiency of use.

[0003] For this purpose, a manually controlled two-way valve is proposed. Utility Model Content

[0004] The utility model aims to solve the shortcoming of the prior art that there are few passages, and proposes a manually controlled two-way valve.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A manually controlled two-way valve comprises a valve body, a mounting hole penetrating the valve body is arranged on the side of the valve body, a valve core is rotatably mounted in the mounting hole, a first passage inlet and a second passage inlet are arranged at both sides of the top of the valve body, a first passage outlet and a second passage outlet are arranged at both sides of the bottom of the valve body, a first passage three-way hole and a second passage three-way hole are fixedly mounted at both ends of the interior of the valve core, the first passage three-way hole is used to connect the first passage inlet and the first passage outlet to form a passage, and the second passage three-way hole is used to connect the second passage inlet and the second passage outlet to form a passage.

[0007] In a possible design, four corners of the valve body are each provided with penetrating fixing bolt holes, and the valve body is fixed by bolts through the fixing bolt holes.

[0008] In a possible design, a plurality of sealing ring grooves are disposed on the top and the bottom of the valve body, and the plurality of sealing ring grooves are respectively disposed on the circumferences of the first passage inlet, the first passage outlet, the second passage inlet, and the second passage outlet.

[0009] In a possible design, sealing threads are provided at both ends of the inner wall of the mounting hole, two sealing gaskets are slidably installed on the outer wall of the valve body, and sealing nuts with holes and sealing nuts without holes are rotatably installed at both ends of the mounting hole. The sealing nuts with holes and sealing nuts without holes are used to seal the mounting hole by rotating and squeezing the sealing gaskets.

[0010] In a possible design, a limiting hole is provided in the middle position of the top of the valve body, a limiting screw is threadedly connected to the limiting hole, a limiting groove is provided on the outer wall of the valve core, the position of the limiting groove is aligned with the position of the limiting hole, and the valve core is limited by the top of the limiting screw fitting into the limiting groove.

[0011] In a possible design, a leveling vent hole penetrating the valve body is provided on one inner side of the valve body.

[0012] In a possible design, a rotation control hole is provided at one end of the valve core, and the valve core is rotated by connecting a manual or automatic actuator to the rotation control hole.

[0013] In this application, during installation, first install the valve core into the valve body, keep the three-way hole of the valve core in the horizontal direction, align the limit groove with the limit hole, and then screw the limit screw into the limit hole. Then, insert the two sealing gaskets into the valve core from both sides, and push the sealing gaskets into the valve body. After that, install the sealing nut with holes and the sealing nut without holes on both sides, respectively. Both sealing nuts should be tightened to press the sealing gaskets. Since the sealing gaskets are made of flexible material, they will deform and fill the gap after being pressed, thereby ensuring the seal. After installation, the right holes of the two three-way holes of the valve core are connected to the leveling vent holes of the valve body; the upper hole of the three-way hole is connected to the passage inlet. At this time, the passage inlet of the valve body is connected to the leveling vent hole, but not to the passage outlet. If you want to change the on-off state, first loosen the limit screw, and then you can connect the manual or automatic actuator to the rotation control hole of the valve core, and rotate the valve core 90° counterclockwise. At this time, the position of the three-way hole will change accordingly, and the inlet and outlet of the valve body passage will be connected, but not connected to the leveling vent hole on the valve body.

[0014] Beneficial effects:

[0015] In the utility model, a manually controlled two-way valve is described, and the valve body has two passages that do not interfere with each other. By manually or automatically rotating the valve core, the effect of controlling the on-off can be achieved. It can be used in applications where water and gas circuits need to be on and off, and can also be used for zeroing of various transmitters. BRIEF DESCRIPTION OF THE DRAWINGS
