Specific embodiment
It as shown in Figs. 1-2, is a kind of steam trap of high discharge capacity of the utility model, including valve body 1 and valve deck 2, valve
The chamber 3 passed through for fluid is formed between body 1 and valve deck 2, is provided with valve seat 4 in chamber 3, valve seat 4 is fixedly connected with valve body 1,
And the channel 5 being connected with chamber 3 is offered, the top of valve seat 4 is provided with guide rod 6, is arranged with metal clips on guide rod 6
7, one end of metal clips 7 is connect with valve seat 4, and the other end is connected with pressing plate 8, and pressing plate 8 movably covers in the vertical direction
On guide rod 6, the middle part of pressing plate 8 is connected with valve rod 9, and the bottom of valve rod 9 is provided with spool 10, is provided with limited block on valve seat 4
11, the diameter of spool 10 is greater than the distance between limited block 11, and the bottom of valve deck 2 is provided with the first gasket 12, and valve body 1 is the
One gasket 12 offers bayonet on corresponding position, and the second gasket 13, the bottom of the first gasket 12 are provided in bayonet
Portion is provided with several protrusions 14 side by side, and the groove 15 being cooperatively connected with protrusion 14 is provided on the second gasket 13.
Specifically, when condensed water and cold air enter valve body 1 from import, by the chamber 3 between valve body 1 and valve deck 2, this
When chamber 3 in metal clips 7 be straightened condition, spool 10 open, drained with maximum pump discharge, when water temperature increases, metal elastic
7 bending deformation of piece simultaneously pulls spool 10 and valve rod 9 to move upwards, and closes valve power and is gradually increased until and completely closes, when condensed water again
It when secondary entrance, and repeats the above process and carries out hydrophobic, when hydrophobic, the junction of the necessary valve deck of fluid 2 and valve body 1, this is practical
The novel structure and shape for changing conventional seals pad, in the junction of valve body 1 and valve deck 2, setting is close there are two what is be mutually fitted into
Packing, specifically, the protrusion 14 on the first gasket 12 is cooperatively connected with the groove 15 on the second gasket 13, it
Between junction be not straight line so that sealing face contact it is even closer, fluid is not easy directly to leak, and improves hydrophobic
The sealing performance of valve
Close to the entrance of fluid, a boss 16 is extended in the direction that side towards the chamber 3 of bayonet are located on valve body 1,
Chamfering 17 in the arc-shaped is arranged in the corner of boss 16, increases cushion performance, and fluid is not easy after washing away for a long time to valve
Body 1 and valve deck 2 generate abrasion.
The height of the top surface of boss 16 is greater than the height of 13 junction of the first gasket 12 and the second gasket, so that fluid
It will not enter directly into sealing surface, further reduce a possibility that leaking.
Be provided between the top of boss 16 and the inner wall of valve body 1 one be in arc-shaped buffering suface 18, buffering suface 18 passes through
Screw is removably connect with valve body 1 and boss 16, similarly increases fluid by the cushion performance in face, can with screw
The connection of disassembly facilitates the connection and disassembly that will not be influenced between valve body 1 and valve deck 2 while its installation.
In addition, the surface of buffering suface 18 is coated with nickel-base alloy corrosion-resistant finishes, nickel-base alloy corrosion-resistant finishes is removed with resistance to
It grinds outside performance, anti-oxidant, corrosion-resistant, welding performance increases the service life of valve body.
The above are only specific embodiments of the present invention, but the technical characteristics of the utility model is not limited thereto.Appoint
How based on the utility model, to solve essentially identical technical problem, essentially identical technical effect is realized, it is made
Simple change, equivalent replacement or modification etc., are all covered by among the protection scope of the utility model.
