Abstract
The utility model relates to a water supply and drainage valve, in particular to a hidden-stem wedge gate valve, which comprises a valve body, a hoist, a valve plate and a valve stem. The hidden-stem wedge gate valve is characterized in that a groove is arranged at a position where the valve body is in contact with the valve plate, and a rubber washer is arranged in the groove. The hidden-stem wedge gate valve has the advantages that the structure is simple; the design is reasonable; and since the valve plate falls into the groove during closing, the traditional contact method is changed and the tightness of the valve is improved.
Description
Technical field:
The utility model relates to the plumbing valve, is specifically related to non-rising stem wedge gate valve.
Background technique:
Non-rising stem wedge gate valve is generally used for connecting in water supply and sewerage pipeline or blocking medium, and its motion thread is positioned at valve inner, and in opening-closing process, valve rod only rotates, and drives valve plate lifting in gate valve.Existing non-rising stem wedge gate valve valve plate and Gate-valve sealing are not good, and the phenomenon such as often occur leaking.
The model utility content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, and a kind of non-rising stem wedge gate valve of good airproof performance is provided.
Technical problem to be solved in the utility model realizes by the following technical solutions.
Non-rising stem wedge gate valve comprises valve body, hoist, valve plate and valve rod, it is characterized in that: described valve body and valve plate contact position are provided with groove.
Be provided with rubber washer in described groove, increase sealing.
The utility model is simple in structure, and is reasonable in design, and valve plate falls in closing process in groove, changes the way of contact in the past, increased the sealing of valve.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
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.
Non-rising stem wedge gate valve, comprise valve body 1, hoist 2, valve plate 3 and valve rod 4 as shown in Figure 1, and valve body 1 is provided with groove 5 with valve plate 3 contact position, is provided with rubber washer 6 in groove 5.
