Abstract
The utility model provides a durable valve, comprising a valve rod and a valve door. The utility model is characterized in that a connecting groove at the connecting position of the valve door and the valve rod is a dovetail groove, and the connecting position of the valve rod and the connecting groove is also a shape corresponding with the dovetail groove. The connecting position of the valve door and the valve rod is the improved dovetail groove shape, and the contact surface of the valve door and the valve rod is a slope. Therefore, the connection between the valve rod and the valve door is more firm and reliable. When the valve door is opened and closed, the acting point of force is lower and therefore, the phenomenon that the upper part edge of the connecting groove is worn or damage can not happen. The service life is increased by almost 10 times.
Description
The utility model relates to a kind of valve, especially for the valve in tap water, heating installation and the steam line.
At present, use diameter at the ducted valve of φ 15-25mm, a kind of copper ball valve of normal employing is (referring to Fig. 1, Fig. 2), the spherical valve of this copper ball valve and the joint of valve rod are straight troughs that is leveled up and down, the joint of valve rod be face directly with straight trough corresponding rectangular-shaped, a kind of like this linkage structure form exists a defective significantly: because the junction plane of valve rod and spherical valve is to face instability directly, when switch valve, valve rod is in spherical valve gearing power process, the point of action of power is near valve straight trough top, long and for a long time it, the straight trough edge of spherical valve will wear and tear, junction plane is diminished gradually, and then damage, cause valve rod and spherical valve to be in the slippage state and can't use.People are expecting that the technological scheme that addresses the above problem produces as early as possible.
The utility model is to realize that spherical valve combines with valve rod firmly and the purpose of long service life.
In order to achieve the above object, its technological scheme is: it comprises valve rod and valve, it is characterized in that: the connecting groove of valve and valve rod joint is a dovetail groove, and the joint of valve rod and connecting groove also is and the corresponding shape of dovetail groove.
The utility model compared with prior art has the following advantages and good effect: the joint of valve and valve rod all is improved to the dovetail groove shape, both surface of contact are the inclined-planes, thereby it is more solid and reliable that valve rod is connected with valve, when switch valve, the point of action of power is by following, thereby can not wear and tear or damage the phenomenon of connecting groove top edge, and improve nearly 10 times working life, brought convenience to the user.
Fig. 1 is the sectional view of prior art structure;
Fig. 2 is the valve of prior art and the schematic representation of valve rod;
Fig. 3 is a structure sectional view of the present utility model;
Fig. 4 is the schematic representation of valve of the present utility model and valve rod.
1, valve rod; 2, valve; 3, connecting groove; 4, valve body; 5, pipe joint.
Referring to Fig. 3, Fig. 4, lean on last phenomenon in order to overcome prior art valve rod 1 and valve 2 in conjunction with insecure point of action with power, the connecting groove 3 of valve 2 (present embodiment employing spherical valve) is improved to dovetail groove, correspondingly corresponding shape with dovetail groove is also made in valve rod 1 joint, because the dovetail groove shape is up-small and down-big, the side is the inclined-plane, thereby after valve rod 1 is inserted into valve 2, both are in conjunction with solid and reliable, and its force position is near root (root place intensity height).In switching process, valve rod 1 can not become flexible slippage with valve 2, can or not damage the wearing and tearing of connecting groove 3 top edge, has improved working life greatly.
Claims (1)
