Abstract
The invention provides a flange type sluice valve, comprising a valve body, flashboards, flanges, a valve cap and a valve body, wherein valve seats are mounted at the left and right sides inside the valve body, respectively; the wedge-shaped flashboard is mounted in each valve seat; the flanges are assembled at the joints of the two ends of the valve body and a pipeline; the valve body is connected with the valve cap by means of a bolt; the valve rod is mounted at the middle part of the valve cover; the lower end of the valve rod is connected to a valve plate; a valve rod nut is mounted on the upper part of the valve rod; the upper end of the valve rod nut is connected with a handwheel; and a sealing rubber ring is arranged at the joint of the valve body and the flange. The flange type sluice valve has the beneficial effects of light on-off operation, reliable sealing, low fluid resistance, low erosion and corrosion of the sealed surface caused by a medium, simple structure, short structure, good manufacturability and wide application range.
Description
Technical field
The invention belongs to valve field, especially relate to a kind of flange-type gate valve.
Background technique
Flange Gate Valves is that Placement is the gate valve of flange, and this Placement is the most common.Reliable and stable when Flange Gate Valves uses in pipeline, so mistake adopts Flange Gate Valves on pressure duct.The general gate valve that uses on the market for a long time is because structure is complicated, and ubiquity and leaked or the phenomenon of getting rusty, and is prone to cause erosion and scratch between the sealing surface, and maintenance is difficulty relatively.
Summary of the invention
The problem that the present invention will solve provides light and handy, the reliable sealing flange-type gate valve of a kind of switch.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of flange-type gate valve comprises valve body, flashboard, flange, valve gap, valve rod; The left and right sides is equipped with valve seat respectively in the valve body, and the wedge-type flashboard is installed in the valve seat, and valve body two ends and pipeline connection port place are equipped with flange; Valve body is connected with the valve gap bolt; Valve rod is equipped with at the valve gap middle part, and the valve rod lower end is connected with valve plate, and Stem Mut is equipped with on valve rod top; The Stem Mut upper end is connected with handwheel, and said valve body and said flange connections are provided with O-ring seal.
Advantage and good effect that the present invention has are: owing to adopt technique scheme, this gate valve switch is light and handy, sealing is reliable, and fluid resistance is little, and sealing surface receives washing away of medium and corrodes for a short time, and body is simple, and structure length is short, and anufacturability is good, and is applied widely.

Embodiment
As shown in Figure 1, the present invention is a kind of flange-type gate valve, comprises valve body 2, flashboard 3, flange 4, valve gap 5, valve rod 6; The left and right sides is equipped with valve seat 1 respectively in the valve body 2, and wedge-type flashboard 3 is installed in the valve seat 1, and valve body 2 two ends and pipeline connection port place are equipped with flange 4; Valve body 2 is connected with valve gap 5 bolts; Valve rod 6 is equipped with at valve gap 5 middle parts, and 6 ends are connected with valve plate under the valve rod, and Stem Mut 7 is equipped with on valve rod 6 tops; Stem Mut 7 upper ends are connected with handwheel 8, and said valve body 2 is provided with O-ring seal 9 with said flange 4 joints.
The working procedure of this instance:
Flange-type gate valve notice in use are following:
1. in must the check valve chamber before installing and position such as sealing surface, not allowing dirt or sand grains adheres to; 2. each connection part bolt requires evenly to tighten; 3. inspection filler position requires to compress, and has both guaranteed the sealing of filler, also will guarantee the flashboard unlatching flexibly; 4. the user is before mounted valve, must check and correction valve model, Conncetion cimension and note MEDIA FLOW to, guarantee to require conformity with valve; 5. the user must reserve the requisite space of valve driving when mounted valve; 6. the wiring of drive unit must be undertaken by circuti diagram; 7. the necessary time-based maintenance of gate valve must not arbitrarily be collided and push, in order to avoid the influence sealing.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
Claims (1)
