Abstract
The utility model provides a flange gate valve which comprises a valve body, a valve board, flanges, a valve cover and a valve rod. Valve seats are arranged on the left side and the right side inside the valve body, wedge gates are arranged inside the valve seats, the flanges are arranged on the connecting ports of two ends of the valve body and pipelines, the valve body is connected with the valve cover through bolts, the valve rod is arranged on the middle portion of the valve cover, the lower end of the valve rod is connected with a valve plate, a valve rod nut is arranged on the upper portion of the valve rod, the upper end of the valve rod nut is connected with a hand wheel, and silicon seal rings are arranged on the connecting portions of the valve body and the flanges. The flange gate valve has the advantages of being light and handy in opening and closing, reliable in seal, small in hydraulic resistance, small in erosion and corrosion of medium on sealing surfaces, simple in shape, short in structure length, good in manufacturability, and wide in application range.
Description
Technical field
The utility model belongs to valve field, especially relates 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 easily causes erosion and scratch between the sealing surface, and maintenance is difficulty relatively.
Summary of the invention
Problem to be solved in the utility model provides that a kind of switch is light and handy, the reliable flange-type gate valve of sealing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of flange-type gate valve, comprise valve body, flashboard, flange, valve gap, valve rod, valve seat is equipped with respectively in the left and right sides in the valve body, the wedge-type flashboard is installed in the valve seat, 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, the valve rod lower end is connected with valve plate, Stem Mut is equipped with on valve rod top, and the Stem Mut upper end is connected with handwheel, and described valve body and described flange connections are provided with O-ring seal.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, this gate valve switch is light and handy, sealing is reliable, and fluid resistance is little, sealing surface is subjected to washing away of medium and corrodes littlely, and body is simple, and structure length is short, anufacturability is good, and is applied widely.

Embodiment
As shown in Figure 1, the utility model is a kind of flange-type gate valve, comprise valve body 2, flashboard 3, flange 4, valve gap 5, valve rod 6, valve seat 1 is equipped with respectively in the valve body 2 interior left and right sides, wedge-type flashboard 3 is installed in the valve seat 1, 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, 6 ends are connected with valve plate under the valve rod, Stem Mut 7 is equipped with on valve rod 6 tops, and Stem Mut 7 upper ends are connected with handwheel 8, and described valve body 2 is provided with O-ring seal 9 with described flange 4 joints.
The working procedure of this example:
Flange-type gate valve notice in use are as follows:
1. with the position such as sealing surface, do not allowed dirt or sand grains to adhere in must the check valve chamber before installing; 2. each connection part bolt requires evenly to tighten; 3. check that the filler position requires to compress, 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 that valve drives 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 impact sealing.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
