Problems solved by technology
Under the condition of large fluid impact force, the structure may have poor stability in the opening and closing process of the gate assembly
[0007] During the opening and closing process of conventional valves, the gate assembly is eccentric during the opening and closing process due to the impact of the medium, thereby accelerating the wear of the sealing surface

Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0027] Such as figure 1 As shown, the valve body 1 is placed on the horizontal ground, the valve cavity of the valve body 1 is left-right symmetrical, and the bottom of the cavity is a horn shape with left and right expansion, and the axis is in the horizontal direction, and a left-right symmetrical left Valve seat 2 and right valve seat 7.
[0028] The left valve seat 2 and the right valve seat 7 have the same structure, the main body is a cylinder, and the outer surface is processed with installation steps. It is stuck in the cavity of the valve body 1 through a stepped structure.
[0029] A left flashboard 3 and a right flashboard 6 are installed between the left valve 2 and the right valve seat 7, and are symmetrically fixed.
[0030] figure 1 Shown in , the left gate 3 and the right gate 6 are installed through the gate frame 4 and the...

The invention belongs to a valve technology of a steam pipeline system, and particularly relates to a parallel double gate plate with guide ribs. The parallel double gate plate with the guide ribs comprises a valve body, a left valve seat and a right valve seat, wherein the left valve seat and the right valve seat are symmetrically and fixedly arranged in the valve body; a left gate plate body anda right gate plate body are symmetrically and fixedly arranged between the left valve seat and the right valve seat; a gate plate frame is arranged between the left valve seat and the right valve seat, and provided with the guide ribs; the valve body is provided with guide grooves; and the guide ribs and the guide grooves are matched. The gate plate frame is provided with the guide rib structures, and the guide ribs are in contact with the guide grooves in the opening and closing process of the valve, so that a whole gate plate assembly can move up and down linearly in the guide grooves, theeccentricity of the gate plate assembly in the opening and closing process can be effectively controlled, and the stability of the opening and closing movement process of the gate plate assembly is good.
Description
technical field [0001] The invention belongs to the valve technology of a steam pipeline system, and in particular relates to a wedge-tight parallel double flashboard with guiding ribs. Background technique [0002] Parallel double gate valves are suitable for closed-circuit equipment on pipelines where the medium is water and sewage. Non-pneumatic double gate valves are allowed to be used for regulating flow and emptying. Widely used in petroleum, chemical, pharmaceutical, electric power and other industries. [0003] It is used for opening and closing on pipelines of steam, water, oil and other media with nominal pressure ≤ 1.0MPa. There are parallel double gate valves, parallel single gate valves, rising stem parallel double gate valves, and rising stem parallel single gate valves. [0004] Parallel double disc gate valve is a kind of ceramic gate valve. Therefore, its structure and working principle are consistent with those of gate valves. The opening and closing bod...
