Description

The slat belt valve

Technical field

The utility model relates to valve field, especially, relates to a kind of slat belt valve.

Background technique

At present, the place that has in the thermal power plant etc. solid-gas, solid-liquid, solid-gas-liquid fluid-mixing to flow uses disconnecting link valve or slat belt valve to realize effective break-make of such fluid usually.At present; Slat belt valve commonly used all is in the level of valve or vertically on the diametric(al) rotatingshaft is set that when opening valve, the part of valve plate can turn in the valve opening; And whole valve plate is in the valve opening position intermediate, makes and can be hindered when the dust-like fluid flows through; On the other hand, existing this type valve, the diameter of its valve plate is less than or equals the pore size of valve opening, makes that like this sealability of valve is bad.

The model utility content

The utility model purpose is to provide a kind of slat belt valve, and existing turning plate valve switch difficulty is big to solve, the technical problem of sealing effect difference.

For realizing above-mentioned purpose, the utility model provides a kind of slat belt valve, comprising: valve body and valve plate; Valve body is provided with valve opening; Valve plate is the shutoff valve opening movably, and the slat belt valve also has pivot, and pivot comprises running shaft and turns handle; First end that turns handle is connected with valve plate, and second end that turns handle is connected with running shaft is vertical; Running shaft is connected with cylinder.

That further, turns handle and running shaft is connected to that flat key is connected or square key connects or spline connects or flat side is connected or solid welding connects or pin is solidly connected.

Further, turn and also be provided with regulating block between handle and the valve plate.

Further, the perisporium of valve opening is provided with seal washer.

Further, valve body comprises first valve casing, second valve casing and connection rib, and first valve casing is fixedly connected through connection rib with second valve casing, and first valve casing, second valve casing and connection rib surround valve pocket, and pivot is arranged in the valve pocket.

Further, running shaft is connected through connecting lever with cylinder, and an end of connecting lever is connected on the running shaft, and an other end of connecting lever is connected on the piston rod of cylinder.

Further, the roughness of the wall of valve body is

The utlity model has following beneficial effect: the slat belt valve of the utility model is owing to adopt pivot and the upset of cylinder valve plate; And the turning handle and can adjust with being connected to of valve plate and be connected of pivot; Make that valve plate upset is easier, the sealing effect of valve plate and valve body is better, fluid to pass through efficient higher; On the other hand, under the equal bore the shared volume of this slat belt valve less than Flap valve volume commonly used.

Except top described purpose, feature and advantage, the utility model also has other purpose, feature and advantage.To do further detailed explanation to the utility model with reference to figure below.

Description of drawings

The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
