Abstract

The invention relates to a gate valve. The gate valve is characterized by comprising a valve body, a guide device, a valve plate, a valve cover, a lead screw and a hand wheel. The valve body is hollow in the vertical direction, and the guide device stretches into the cavity of the valve body horizontally from back to front. The guide device is hollow in the horizontal direction, and the valve plate stretches out of the front and rear ends of the cavity of the guide device in the mode of being capable of horizontally moving front and back. The valve cover is fixedly connected to the rear end of the guide device and is hollow in the horizontal direction, the lead screw is horizontally arranged in the cavity of the valve cover, the front end of the lead screw is fixedly connected with the valve plate, and the rear end of the lead screw stretches out of the cavity of the valve cover to be fixedly connected with the hand wheel. Compared with the prior art, the gate valve is simple and reasonable in structure, good in sealing performance, not prone to blockage, convenient to maintain and long in service life.

Description

A kind of gate valve
Technical field
The present invention relates to a kind of gate valve.
Background technique
At present, the gate valve of each manufacturer production is that the size in flashboard, active chamber, stroke chamber is substantially equal by basic comprisings such as hydraulic jack, push rod, flashboard, framework, rollers.When needing to close active chamber, hydraulic jack starts, and pushrod movement drives flashboard lock to enter active chamber, and when closing active chamber completely, about 60 millimeters of places outside active chamber stayed by flashboard; When needing to open active chamber, hydraulic jack starts, and pushrod movement drives flashboard to extract active chamber, and when opening completely, the stroke chamber outside active chamber all extracted by flashboard.Owing to having roller, angle steel or the round steel of holding flashboard in the active chamber of Flow of Goods and Materials, easily extension, slag inclusion and material, roller, angle steel or round steel also easily wear and tear, are out of shape, thus cause flashboard jam, are mainly easily not closed completely.
Summary of the invention
Technical problem to be solved by this invention is to provide the gate valve of a kind of simple and reasonable, good airproof performance, not easily jam, easy to maintenance and long service life.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of gate valve, comprise valve body, guiding device, valve plate, valve gap, screw mandrel and handwheel, described valve body is vertical direction hollow shape, described guiding device level stretches in the hollow cavity of described valve body 1 before backward, described guiding device is substantially horizontal hollow shape, described valve plate can the hollow cavity rear and front end of stretching out described guiding device of horizontal shifting, described valve gap is fixedly connected on the rear end of described guiding device, described valve gap is substantially horizontal hollow shape, described screw mandrel level is placed in the hollow cavity of described valve gap, the front end of described leading screw is fixedly connected with described valve plate, the hollow cavity that described valve gap is stretched out in the rear end of described leading screw is fixedly connected with described handwheel.
Further, the rear end of described valve gap hollow cavity is fixedly installed thrust ball bearing, and described thrust ball bearing is sleeved on described screw mandrel.
Further, described guiding device and valve gap joint are fixedly installed sealing baffle, and described sealing baffle is sleeved on described valve plate.
Further, wool felt is provided with between described guiding device and described sealing baffle.
Further, described screw mandrel and described handwheel joint are provided with silk braid, and described silk braid is sleeved on the rear end of described screw mandrel.
The invention has the beneficial effects as follows: rotation hand wheel, handwheel drives screw mandrel to move forward, and screw mandrel moves and drives valve plate to move forward, and guiding device can provide leading role for valve plate moves, and overall structure is simple; Sealing baffle and wool felt energy effective sealing valve gap, the sealing of lifting device; It is more smooth and easy that thrust ball bearing makes screw mandrel rotate, and this device entirety is jam, easy to maintenance and long service life not easily.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of gate valve of the present invention.
In accompanying drawing, the list of parts representated by each label is as follows:
1, valve body, 2, guiding device, 3, valve plate, 4, valve gap, 5, screw mandrel, 6, handwheel, 7, thrust ball bearing, 8, sealing baffle, 9, wool felt, 10, silk braid.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
6. as shown in Figure 1, a kind of gate valve, it is characterized in that: comprise valve body 1, guiding device 2, valve plate 3, valve gap 4, screw mandrel 5 and handwheel 6, described valve body 1 is vertical direction hollow shape, described guiding device 2 level stretches in the hollow cavity of described valve body 1 before backward, described guiding device 2 is substantially horizontal hollow shape, described valve plate 1 can the hollow cavity rear and front end of stretching out described guiding device 2 of horizontal shifting, described valve gap 4 is fixedly connected on the rear end of described guiding device 2, described valve gap 4 is substantially horizontal hollow shape, described screw mandrel 5 level is placed in the hollow cavity of described valve gap 4, the front end of described leading screw 5 is fixedly connected with described valve plate 3, the hollow cavity that described valve gap 4 is stretched out in the rear end of described leading screw 5 is fixedly connected with described handwheel 6.
The rear end of described valve gap 4 hollow cavity is fixedly installed thrust ball bearing 7, and described thrust ball bearing 7 is sleeved on described screw mandrel 5.
Described guiding device 2 and valve gap 4 joint are fixedly installed sealing baffle 8, and described sealing baffle 8 is sleeved on described valve plate 3.
Wool felt 9 is provided with between described guiding device 2 and described sealing baffle 8.
Described screw mandrel 5 is provided with silk braid 10 with described handwheel 6 joint, and described silk braid 10 is sleeved on the rear end of described screw mandrel 5.
Implement this device, when needs valve body 1, rotation hand wheel 6, handwheel 6 drives screw mandrel 5 to move forward, and screw mandrel 5 moves and drives valve plate 3 to move forward, and guiding device 2 can provide leading role for valve plate 3 moves, and overall structure is simple; Sealing baffle 8 and wool felt 9 energy effective sealing valve gap 4, the sealing of lifting device; It is more smooth and easy that thrust ball bearing 7 makes screw mandrel 5 rotate, and this device entirety is jam, easy to maintenance and long service life not easily.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
