Abstract
The utility model relates to a valve rod used on a stop valve. The valve rod used on the stop valve is provided with a valve rod body. A convex disc with radial dimension larger than the diameter of the valve rod body is arranged at the lower end of the valve body, and a first sealing rod and a second sealing rod are respectively arranged on two sides of the lower end of the convex disc. Length of the first sealing rod is smaller than the length of the second sealing rod, and a separating groove is formed between the first sealing rod and the second sealing rod. According to the valve rod used on the stop valve, the first sealing rod and the second sealing rod which are different in height are arranged at the lower end of the valve rod body, and the first sealing rod and the second sealing rod can be inserted in a pipe exit working cavity and a pipe entry working cavity which are communicated in a valve seat in sequence when the valve rod used on the stop valve is used.
Description
Technical field
The utility model relates to a kind of stop valve valve rod.
Background technique
The stem structure of stop valve in the past is simple, and manufacturing process is complicated.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of stop valve valve rod is provided, solve in the past stop valve stem structure complexity, the poor defective of sealing effect in the use.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of stop valve valve rod, has valve stem body, described valve stem body lower end is provided with radial dimension greater than the protruding dish of valve stem body diameter, both sides, described protruding dish lower end are respectively arranged with the first seal bar and the second seal bar, the length of described the first seal bar is formed with separate slot less than the length of the second seal bar between the first seal bar and the second seal bar.
Further, described valve stem body, protruding dish, the first seal bar and the second seal bar are structure as a whole.
The beneficial effects of the utility model are: a kind of stop valve valve rod is provided, two the first seal bar and the second seal bar that height is different is set in the valve stem body lower end, in use can insert successively in the valve seat communicate go out to manage active chamber and inlet pipe active chamber.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of valve rod;
Wherein: 1, valve stem body, the 2, first seal bar, the 3, second seal bar, 4, protruding dish.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of stop valve valve rod as shown in Figure 1, has valve stem body 1, described valve stem body 1 lower end is provided with radial dimension greater than the protruding dish 4 of valve stem body 1 diameter, both sides, protruding dish 4 lower end are respectively arranged with the first seal bar 2 and the second seal bar 3, the length of the first seal bar 2 is less than the length of the second seal bar 3, be formed with separate slot between the first seal bar 2 and the second seal bar 3, valve stem body 1, protruding dish 4, the first seal bar 2 and the second seal bar 3 are structure as a whole.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
