Problems solved by technology

[0004] In the prior art, the shut-off valve and the check valve are two different valves. When the shut-off valve and the check valve are used in the fluid piping system at the same time, two valves need to be installed, which is very inconvenient.

Embodiment 1

[0029] A double-effect control valve, refer to Figure 1-Figure 3 As shown, it includes a hollow valve body 1 and an outlet 3 of an inlet 2 located at both ends of the valve body 1. A valve control part is arranged in the valve body 1. The valve control part includes a horizontally arranged conduit 4, and a sealing guide is arranged in the conduit 4. The guide rod 5 and the inlet plug 6 and the outlet plug 7 that are respectively matched with the inlet 2 and the outlet 3 at both ends of the guide rod 5 are provided outside the guide rod 5 with an elastic layer to ensure its sealing and moving cooperation with the conduit 4, Between the conduit 4 and the valve body 1, there is a driving part that drives the guide rod 5 to move. The drive part includes a drive tube 9 that extends vertically from the outer wall of the conduit 4 to the outer wall of the valve body 1 and communicates with the inside of the conduit 4, on the guide rod 5. A fitting groove 501 extending axially along ...

Embodiment 2

[0035] This embodiment is aimed at the situation that the flow in the valve body has been blocked by deposits in the valve body, and an improvement is made on the basis of embodiment 1. Refer to Figure 4 As shown, the guide rod 5 includes a middle section 502 and a fitting section 503 fixed to the inlet plug 6 and the outlet plug 7 respectively. An elastic layer is arranged on the outer wall of the fitting section 503 so as to ensure that it is always in a sealed movement with the catheter 4 during its movement. In the matched state, the matching groove 501 is located on the middle section 502, and an electromagnetic control mechanism is arranged between the matching section 503 and the middle section 502. The plugs 7 block the inlet 2 and the outlet 3 respectively, and a sealed cavity is formed inside the valve body at this time, so that lateral movement of deposits can be avoided.

[0036] The concrete setting of electromagnetic control mechanism is, comprises the electromagn...

Abstract

The invention relates to the technical field of valves, and discloses a double-effect control valve which comprises a hollow valve body and outlets located in inlets in the two ends of the valve body.A valve control part is arranged in the valve body. The valve control part comprises a horizontally-arranged guide pipe, a guide rod arranged in the guide pipe in a sealed and guided mode, an inlet plug and an outlet plug, the inlet plug and the outlet plug are located at the two ends of the guide rod and matched with the inlet and the outlet respectively, a driving part for driving the guide rodto move is arranged between the guide pipe and the valve body, and a discharging part for discharging sediments in the valve body is arranged on the valve body. A stirring mechanism for slowing downthe deposition rate of fluid in the valve body is arranged in the valve body, the valve can be switched between the stop valve and the check valve, and meanwhile the risk that the valve body is blocked can be remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a double-effect control valve. Background technique [0002] Globe valve is a forced sealing valve, its working principle is to set valve disc and valve seat inside the valve body, the valve disc is a movable part, the valve seat is a sealing part, and the valve disc and valve seat are provided with sealing surfaces; When the sealing surface of the disc and the sealing surface of the valve seat fit together, the globe valve is in the cut-off state; when the sealing surface of the disc is separated from the sealing surface of the valve seat, the globe valve is in the conduction state. [0003] Check valve refers to the valve that relies on the flow of the medium itself to automatically open and close the disc to prevent the backflow of the medium. When the fluid medium in the pipeline flows forward, the valve disc leaves the valve seat under the action of the fluid, and the check ...
