Abstract
The utility model relates to a valve body separately welds angie type non return door for nuclear island. It includes valve body, down valve body, valve clack, spring, exports the runner in the middle of going up the valve body upper end, and it is the valve clack chamber to go up in the middle of the valve body lower extreme, and the design of valve clack intracavity has an uniform distributor, and the design all around of round hole in the middle of the uniform distributor, round hole has a plurality of equipartition holes, and the valve clack includes a valve disc and guide post, and the guide post upper end lies in the round hole, on the valve disc is connected to the guide post lower extreme, goes up the welding of valve body lower extreme in valve body upper end down, and lower valve body is above -mentioned to be equipped with the disk seat, lies in the disk seat below the valve disc. The advantage is that two directions entering can be followed to the medium, reduces valve installation quantity, existing valve body design is butt -welding connection, and the volume diminishes, weight becomes light, existing valve body material WB36, the high -pressure machine who is applicable to the nuclear power system organizes, design the valve clack at present and be whole with the valve rod, with spring direction, low in manufacturing cost.
Description
Technical field
This utility model relates to field of check valves, is specifically related to a kind of nuclear island valve body separately welding angie type non-return door.
Background technology
Valve is industrial conventional a kind of pipe control equipment.The refluence of non-return gate control medium, single flow direction, it is achieved system protection controls requirement.Existing non-return family of power and influence's body is flange with valve gap or threadeds, valve pocket generally can-like volume so that valve weight increases, volume becomes big, cost is high；Flap is to be completed by the supporting construction in valve rod and valve body at the positioning and guiding of valve pocket, and structure is complicated, parts are many.Due to flap weight, the resistance of medium circulation is big, and fairlead easily weares and teares, and produces some deviation, easily weigh sealing surface wounded during flap return valve seat.Non-return door can only be useful in use infrequently, the system use that pressure reduction is stable.
Summary of the invention
This project is to overcome the deficiencies in the prior art, it is provided that a kind of valve body separately welding angie type non-return door, by the welding of upper and lower valve body, volume is little, low cost, it is adaptable to work is frequently, importing and exporting the nuclear island system that pressure at two ends is stable, medium can enter from both direction, reduces valve and installs quantity.
In order to reach foregoing invention purpose, the utility model proposes techniques below scheme:
Nuclear island valve body separately welding angie type non-return door, it includes upper valve body, lower valve body, flap, spring, it is outlet flow in the middle of upper valve body upper end, it it is flap chamber in the middle of upper valve body lower end, flap intracavity is designed with a uniform device, a circular hole in the middle of uniform device, circular hole surrounding is designed with some uniform holes, flap includes a valve disc and lead, lead upper end is positioned at circular hole, and lead lower end connects on valve disc, and upper valve body lower end is welded on lower valve body upper end, lower valve body is fitted with valve seat, is positioned on valve seat below valve disc.
The circular hole lower end of described uniform device has ring-shaped step, and lead outer sheath is equipped with spring, and spring upper end withstands on ring-shaped step, and lower spring end withstands on above valve disc.
Described lower valve body is horn shape valve body, and lower valve design has two inlet channel, two rectangular shapes of inlet channel.
Described upper valve body and lower valve body all use WB36 steel.
One layer of hard alloy of built-up welding on the sealing surface that described valve disc lower end contacts with valve seat.
The utility model has the advantages that medium can enter from both direction, reduce valve and quantity is installed；Former valve design is Flange joint, and volume is big, heavier-weight.Existing valve design is that butt welding connects, and volume diminishes, weight；Former valve body material 25 steel, it is adaptable to the common unit etc. of power system.Existing valve body material WB36, it is adaptable to the high pressure unit of nuclear power system；Original design have the parts such as fairlead, valve rod.Now design flap and valve rod are overall, guide with spring, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is uniform device top view of the present utility model.
Fig. 3 is the schematic diagram of flap of the present utility model.
Fig. 4 is partial enlarged drawing of the present utility model.
Detailed description of the invention
1-4 referring to the drawings, nuclear island valve body separately welding angie type non-return door, it includes upper valve body 1, lower valve body 2, flap 3, spring 4, upper valve body 1 is outlet flow in the middle of upper end, it is flap chamber in the middle of upper valve body 1 lower end, flap intracavity is designed with a uniform device 5, a circular hole 51 in the middle of uniform device 5, circular hole 51 surrounding is designed with some uniform holes 52, flap 3 includes a valve disc 31 and lead 32, lead 32 upper end is positioned at circular hole 51, lead 32 lower end connects on valve disc 31, upper valve body 1 lower end is welded on lower valve body 2 upper end, lower valve body 2 is fitted with valve seat 6, it is positioned at below valve disc 31 on valve seat 6.
Circular hole 51 lower end of described uniform device 5 has ring-shaped step 53, and lead 32 outer sheath withstands on ring-shaped step 53 equipped with spring 4, spring 4 upper end, and spring 4 lower end withstands on above valve disc 31.
Described lower valve body 2 is horn shape valve body, and lower valve body 2 is designed with two inlet channel, two rectangular shapes of inlet channel.
Described upper valve body 1 and lower valve body 2 all use WB36 steel.
One layer of hard alloy 33 of built-up welding on the sealing surface that described valve disc 31 lower end contacts with valve seat 6.
When this utility model uses, medium enters from two inlet channel of lower valve body, under the effect of pressure medium, flap is backed down, valve turns on, and when medium does not flows, flap resets under the action of the spring, flap is sealed on valve seat, prevent medium back flow, uniform device design from not only ensure that flap is steady up and down, and can water conservancy diversion.
