Abstract
The utility model discloses an integral type valve seat structure with a filter screen, which comprises a valve seat and a filter screen. The filter screen (4) is fixedly arranged on the valve seat (3), and the filter screen and the valve seat are integrally connected. When the filter screen is blocked by large particles and the valve is insufficient in circulation, users do not need to change the whole valve but dismount the valve seat, clean the valve seat and reassemble the valve seat for use, and the valve seat can be in operation again. The integral type valve seat structure with the filter screen is simple in structure and saves production cost, the machine unit can be in long-term operation, and the valve can be overhauled rapidly.
Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of valve seat.
Background technique
As everyone knows; Valve is a crucial controlling component in the fluid delivery system; It has by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release, especially the control media one-way flow is played crucial effect, owing to can carry large granular impurity unavoidably secretly in the medium; In a single day these large granular impurities flow into the sealing surface place between valve body and the flap, will damage the sealing face.
As shown in Figure 1, traditional structure is that this filtrating equipment 1 is separated from each other with valve seat 2 at the front end that filters power conduit mounting filtering device 1 separately; Or at valve body medium entrance point mounting filtering net separately, to prevent the inflow of large granular impurity, still; When filter screen is had influence on the negotiability of valve by above-mentioned large granular impurity obstruction; Will cause whole valve not satisfy operating mode and must all change or scrap, thereby influence manufacturing efficiency, working life is short.
The model utility content
To above-mentioned deficiency, the integrated type valve seat construction that has filter screen that the utility model provides a kind of simple in structure, long service life and is easy to unpick and wash.
The utility model is to realize through such technological scheme: a kind of integrated type valve seat construction that has filter screen, comprise valve seat and filter screen, and said filter screen is fixedly installed on the valve seat.
Said filter screen is more than 2, and it is parallel to be fixedly installed on the below of valve seat and power conduit is separated, and therefore, the large granular impurity from the medium that power conduit flows into is filtered the net retaining outside valve.
The utility model has overcome that filter screen and valve seat are split type and not easily removable and washable technical problem in the existing technology; It adopts filter screen and valve seat monolithic construction; Therefore; The large granular impurity of from the medium that power conduit flows into, carrying secretly is filtered net effectively to be stopped and can not get into the sealing surface between valve seat and valve seat and the flap, and then can prevent that the sealing face from being scratched by large granular impurity, the leakproofness when having guaranteed valve closing; When filter screen is caused the valve negotiability not enough by large granular impurity obstruction back, need not whole valve is all changed, only need to dismantle and can ressemble use after lower valve base cleans up; Valve can put into operation once more, and it is simple in structure, has practiced thrift cost of production; But and the unit long-time running, valve can overhaul fast, has therefore improved the operational efficiency of unit; Improve the working life of valve, also practiced thrift operating cost simultaneously greatly.
Description of drawings
Fig. 1 is the structural drawing of filter screen and valve seat in the existing technology.
Fig. 2 is for having the integrated type valve seat construction figure of filter screen among the utility model embodiment.
Embodiment
For purpose, technological scheme and the beneficial effect that is expressly understood the utility model more, below in conjunction with accompanying drawing the utility model is done further explanation, but the protection domain of the utility model is not limited in following examples.
As shown in Figure 2, a kind of integrated type valve seat construction that has filter screen comprises valve seat 3 and filter screen 4, and said filter screen 4 is fixedly installed on the valve seat 3; Said filter screen 4 is 2; It is parallel to be fixedly installed on the below of valve seat 3 and power conduit 5 is separated; The flow direction of medium is shown in the arrow among Fig. 2, and in the process of media flow, the large granular impurity of wherein carrying secretly is filtered net 4 and is blocked in outside the valve seat 3; Prevent that the sealing surface between valve seat 3 and the flap from sustaining damage, thus the leakproofness when having guaranteed valve closing; When filter screen 4 is stopped up by large granular impurity, only need pull down valve seat 3, the filter screen 4 that is fixedly connected with it also is removed naturally, after it is cleaned up, has ressembled valve seat 3, can put into operation once more.
Claims (2)
1. an integrated type valve seat construction that has filter screen comprises valve seat and filter screen, it is characterized in that: said filter screen (4) is fixedly installed on the valve seat (3).
2. the integrated type valve seat construction that has filter screen as claimed in claim 1 is characterized in that: said filter screen (4) is more than 2, and it is parallel to be fixedly installed on the below of valve seat (3) and power conduit (5) is separated.
