Abstract
The utility model relates to an airtight valve, and in particular relates to a manual dual-connecting rod airtight valve which is applied to civil air-defense construction. The manual dual-connecting rod airtight valve comprises a valve body; a sealing port is arranged on the left side wall of the valve body; an air vent is arranged on the right side wall of the valve body; a fixing arm is arranged in the valve body; a main shaft is inserted into the valve body and is in cross joint with the fixing arm; a rotary arm is sleeved on the main shaft and fixedly connected with a connection seat through a connecting rod; a valve plate is fixed at the bottom of the connection seat; the valve plate is in sealing connection with the sealing port; the main shaft is rotatably connected through a drive plate on the side wall of the valve body; the bottom of the drive plate is connected with a handle; the side wall of the drive plate is provided with a locking shaft and is in locking connection with the valve body; and the bottom of the locking shaft is connected with a fastening handle. The manual dual-connecting rod airtight valve has a simple structure, reduces the opening/closing force, prolongs the service life and is convenient to operate.
Description
Technical field
The utility model patent relates to a kind of sealed valve, relates in particular to a kind of manual double link sealed valve, is used for civil air defense constructions and installations.
Background technique
Sealing system in the present sealed door of the prior art; The structure relative complex; And airtight intensity is not high, is easy to generate the dead angle, thereby causes poison gas to get into engineering inside; And adopting single connecting rod kind of drive, rotational valve plate can not fit simultaneously with sealing surface or separate and valve plate can not be regulated air quantity as requested.
Chinese patent CN201020640607.3 discloses the airtight blast door that a kind of large tunnel civil air defense constructions and installations is used.Comprise door leaf, doorframe, hinge mechanism, locking mechanism, resetting-mechanism, wicket, trench cover plate.Traditional sealed door can not carry out the adjusting of air quantity, can only be the state that opens or closes.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the existing technology, provides a kind of simple in structure, and the manual double link sealed valve of quantity-adjustable.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of manual double link sealed valve comprises valve body, and the left side wall of described valve body is provided with sealed mouth; The right side wall of described valve body is provided with ventilated port, is provided with fixed arm in the described valve body, be plugged with in the described valve body main shaft and with fixed arm cross-under mutually; Be with pivoted arm on the described main shaft; Described pivoted arm is fixedly connected through connecting rod and connecting base, and the bottom of described connecting base is fixed with valve plate, and described valve plate is tightly connected with sealed mouth mutually; The connection that rotates of the dial of described main shaft through the valve body sidewall; The bottom of described dial connects handle, the sidewall of described dial be provided with lock shaft and with valve body interlocking mutually, the bottom of described lock shaft connects pinch grip.
Unclamp pinch grip, handle with sleeve drives pivoted arm through main shaft; Pivoted arm drivening rod again carries out the switching to valve plate; The locking pinch grip can make valve plate stop and being parked in the angle of wanting, and realizes the control air quantity; Close valve plate and can change draft type and valve plate ventilation duct, stop toxic gas to get into engineering inside.
As preferably, described valve plate seals through sealing joint strip with the valve body inwall mutually, and described sealing joint strip and valve body inwall are halved together.
As preferably, described main shaft is provided with two pivoted arms that distribute separately, and the left side wall edge and the right side wall edge of described valve body are respectively equipped with fastener hole.
Therefore, the manual double link sealed valve of the utility model, simple in structure, reduce to open and close and make a concerted effort, increase the service life, easy to operate.
