Abstract
The invention discloses a main steam trap valve of a detachable valve seat. The main steam trap valve is characterized by comprising a valve body and a valve seat complying with the medium circulation volume, wherein the valve seat is provided with a graphite seal ring with the compression deformation amount; the valve seat is connected with a branch body of the valve body; a space between the valve seat and the valve body is sealed with the graphite sealing ring; and the valve body comprises a valve core and a core bag. According to the main steam trap valve disclosed by the invention, once the valve causes leakage as the valve seat is damaged by blowing, the valve only needs to be disassembled, so that the valve seat of the main steam trap valve can be directly taken out and replaced; and therefore, the trap valve can be conveniently repaired, the repair cost is reduced, and the repair time of the trap valve is shortened.
Description
Technical field
The present invention relates to a kind of drain valve, particularly relating to a kind of valve seat of main steam drain valve that makes can directly take out and change, and makes things convenient for the main steam drain valve of detachable valve seat of the maintenance of drain valve.
Background technique
Valve is widely used in the Power Plant system, in the main steam line of power plant, plays an important role.Because the operating mode of valve operation is quite complicated, often faces particularly thorny problems such as high temperature, High Pressure Difference, cavitation, flash distillation, can not despise to the valve destructiveness, situation such as operation that can directly cause valve to take place to leak waiting influencing unit safety and energy consumption raising.When valve opening, tend to produce phenomenons such as cavitation, there is the impurity of some in the power plant system pipeline in addition, can cause fatal destruction to valve.The structure of the detachable valve seat of main steam drain valve utilization of detachable valve seat can effectively solve this valve spool valve seat in actual use and blow and undermine the valve bite, in Frequently Asked Questions such as leak outside.
Summary of the invention
To the problems referred to above, main purpose of the present invention is to provide a kind of valve seat of main steam drain valve that makes directly to take out and to change, and makes things convenient for the main steam drain valve of detachable valve seat of the maintenance of drain valve.
The present invention solves above-mentioned technical problem through following technical proposals: a kind of main steam drain valve of detachable valve seat; Said drain valve comprises valve body and the valve seat that meets the MEDIA FLOW flux; Be equipped with on the said valve seat one have a compress variation graphite seal; Said valve seat is connected with the valve body split, has said carbon seal ring to seal between valve seat and valve body, and said valve body comprises spool and core bag.
In practical implementation example of the present invention, said graphite seal is carbon seal ring.
In practical implementation example of the present invention, transmit with two the fastening screw nut screw-down torques up and down on the valve body graphite seal between valve seat and the valve body is compressed.
Positive progressive effect of the present invention is: the main steam drain valve of detachable valve seat provided by the invention has the following advantages: the present invention is when valve in case because valve seat blows decreases when leakage takes place; Only need the disintegration valve, the valve seat of main steam drain valve can directly be taken out and change.Make things convenient for the maintenance of drain valve, reduce maintenance cost, shorten the engineering time of drain valve.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth internal structure of the present invention.
Fig. 1 is the structural representation of one embodiment of the invention, and is as shown in Figure 1: the present invention includes strength members such as valve seat 3, core bag 4, carbon seal ring 2 and spool 1.Not welding of valve seat and valve body among Fig. 1, but have carbon seal ring to seal between valve seat and valve body.At high temperature still can effectively guarantee the leakproofness of valve base sealing.When valve in case because valve seat blows decreases when taking place to leak, need the disintegration valve, be easy to take out valve seat in the valve body and change, can reach the dismountable effect of valve seat.
The present invention is when valve in case because valve seat blows decreases when taking place to leak, need the disintegration valve, and the valve seat of main steam drain valve can directly be taken out and change.Make things convenient for the maintenance of drain valve, reduce maintenance cost, shorten the engineering time of drain valve.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention, and under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications; These variations and improvement all fall in the scope of the invention that requires protection, and the present invention requires protection domain to be defined by appending claims and equivalent thereof.
Claims (3)
1. the main steam drain valve of a detachable valve seat; It is characterized in that: said drain valve comprises valve body and the valve seat that meets the MEDIA FLOW flux; Be equipped with on the said valve seat one have a compress variation graphite seal; Said valve seat is connected with the valve body split, has said carbon seal ring to seal between valve seat and valve body, and said valve body comprises spool and core bag.
