Abstract
The utility model discloses a novel eccentric ball valve which is provided with a valve body, a hemispheric valve core and a valve rod. The valve body is provided with a flow channel, the hemispheric valve core and the valve rod are installed in a valve seat flow channel, and a sealing valve seat matched with the hemispheric valve core is installed on one side of the flow channel of the valve body. The novel eccentric ball valve is characterized in that the hemispheric valve core is made of stainless steel, and D526 materials are welded on a surface of the sealing valve seat. The novel eccentric ball valve has the advantages that the hardness of the sealing valve seat is different from that of the hemispheric valve core, and possibility of abrasion of the sealing valve seat and the hemispheric valve core is greatly reduced.
Description
Technical field
The utility model relates to valve field, especially relates to a kind of novel eccentric ball valve.
Background technique
In the prior art, the valve seat of ball valve and the contact position of spool since separately the hardness of material cause its wearing and tearing comparatively severe, wearing and tearing occur easily and influence the problem of service valve work.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and a kind of novel eccentric ball valve is provided.
To achieve these goals, the utility model adopts following technological scheme:
A kind of novel eccentric ball valve, it has the valve body that contains flow channel, be installed on the hemisphere spool and the valve rod of valve seat flow channel, one side of this valve body flow channel is equipped with the seal valve seat that cooperates with the hemisphere spool, it is characterized in that, described hemisphere spool adopts stainless steel to make, and described seal valve seat surface soldered has the D526M material.
The beneficial effects of the utility model are: the hardness of seal valve seat and hemisphere spool has nothing in common with each other, and reduces the possibility of the wearing and tearing of the two greatly.
Description of drawings
Fig. 1 is a kind of novel eccentric ball valve structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of novel eccentric ball valve, it has the valve body 10 that contains flow channel, be installed on the hemisphere spool 11 and the valve rod 12 of valve seat flow channel, one side of this valve body flow channel is equipped with the seal valve seat 13 that cooperates with the hemisphere spool, and described hemisphere spool adopts stainless steel to make, and described seal valve seat surface soldered has the D526M material, certainly, also the material of the two can be exchanged the purpose that reaches same.
Be the influence for the internal flow medium of the external environment condition that prevents ball valve work, the surface that can be positioned at valve body is provided with insulating structure layer 14, thus the mutual exchange of barrier valve inside and outside temperature.
The valve rod of valve body is installed passage and is had axle sleeve, filler, and the upper end that is positioned at this installation passage has Gland.
Because seal valve seat surface and hemisphere spool adopt two kinds of materials, reduce the attrition of the two greatly, improve the operating life of whole valve.
