Embodiment
In order to which the technical solution of the utility model is explained further, it is described in detail below by specific embodiment.
A kind of Outside screw stem rising through handwheel type gate valve of fast opening and closing, including valve body 1, bonnet 2, flashboard 3, valve rod 4 and first as Figure 1-4
Lever 5, the valve body 1 have horizontal direction extend pipelined channel, the bonnet 2 be covered on the upper end of valve body 1 and with institute
State valve body 1 to be connected, the valve body 1 and the bonnet 2 are respectively provided with vertical direction and extended and interconnected host cavity 21, institute
State that valve rod 4 is moving up and down to be placed in the host cavity 21, the lower end of valve rod 4 is connected with the flashboard 3；It is characterized in that
First lever 5 of underdrive on the upper end of the valve rod 4 connection driving valve rod 4, described one end of first lever 5 is articulated in the bonnet
2, it is articulated between the upper end of valve rod 4 and the two ends of first lever 5；The upper end of valve rod 4 is connected with first rotating shaft 41,
First lever 5 is equipped with the first strip through-hole 51 slided for first rotating shaft 41, and the strip through-hole 51 is along described first
The bearing of trend extension of lever 5.During unlatching, the first lever 5 is fulcrum with bonnet 2, prizes the motion upwards of valve rod 4, and valve rod 4 drives
Flashboard 3 is moved up, and the unlatching the utility model of flashboard 3 is simple in construction, opens convenient, using laborsaving.
The upper end of bonnet 2 is provided with the first articulated section 22 being articulated with the first lever 5, the company of first lever 5 and bonnet 2
Connect end be the first pivot end, the side wall of articulated section 22 provided with cylinder the first projection 221, first pivot end be provided with
The first circular hole 52 that first projection 221 matches.First lever 5 can install temporarily when in use, it is necessary to when
Wait only need to insert the first circular hole 52 by the first projection 221, and first rotating shaft 41 is inserted into the first strip through-hole 51, just can smoothly be opened
Or closure flashboard 3.
Also include the second lever 5；The upper end of bonnet 2 is provided with the second articulated section 22 being articulated with the second lever 5, described
Second articulated section 22 is equipped with the second projection 221, and second articulated section 22 is with first articulated section 22 on the valve rod 4
