Abstract
The utility model relates to a right-angle throttle valve which comprises a valve body, a valve deck, a valve rod and a valve element, wherein the valve deck is connected and fixed with the valve body, the valve rod is arranged at the center of the valve deck, and the valve element is arranged at the lower end of the valve rod. The valve element rotates along with the valve rod to move up and down and is in sealed connection with an inner cavity of the valve body. The upper end of the valve rod is provided with a valve bonnet which is sleeved on the valve rod and can drive the valve rod to rotate. The valve element is in a cone shape, and the surface of the valve element is provided with a wear-resisting carburized layer. The lower end of the valve bonnet is close to the upper surface of the valve deck. Compared with the prior art, due to the fact that the valve bonnet is arranged at the upper end of the valve rod, impurities and the like cannot enter threads of the valve rod easily; and the wear-resisting carburized layer is arranged on a contact surface of the valve element and the inner cavity of the valve body so that the right-angle throttle valve cannot be abraded easily even if after being used for a long time, and therefore service life of the right-angle throttle valve is prolonged. The right-angle throttle valve is compact in structure, long in service life and good in sealing effect.
Description
Technical field
The utility model relates to the right angle throttle valve, the right angle throttle valve of especially a kind of good sealing effect, long service life.
Background technique
Existing right angle throttle valve generally is comprised of valve body, valve gap, valve rod, handwheel and spool, described valve gap is connected with valve seal and fixes, the valve gap center is equipped with valve rod, the lower end of valve rod is equipped with spool, spool is located between the import and outlet of valve body, spool can rotate with valve rod and move up and down, and is tightly connected with body cavity formation.At present, outside the valve rod of existing right angle throttle valve and the surface of contact of valve gap often are exposed to, there is easily impurity to enter in the screw thread of valve rod, affects the sealing of valve rod; On the other hand, the surface of contact of spool and body cavity also weares and teares because of long-term the use easily, thereby affects the working life of right angle throttle valve.
The model utility content
For the deficiency of above existing right angle throttle valve, the purpose of this utility model provides a kind of valve rod upper end with valve bonnet, the right angle throttle valve of long service life, good sealing effect.
The purpose of this utility model is achieved by the following technical solution:
The right angle throttle valve, comprise valve body, valve gap, valve rod and spool, described valve gap is connected with valve body and fixes, the valve gap center is provided with valve rod, the lower end of valve rod is provided with spool, and spool is located between the import and outlet of valve body, and described valve rod and valve gap are flexibly connected by screw thread, the valve rod upper end is provided with valve bonnet, and valve bonnet is set on the valve rod and can be with ovable valve stem to rotate; Described spool is made as conical structure, and spool can move up and down with the rotation of valve rod, and the sealing surface of spool and valve body can form the gap that reduces gradually, until final formation is tightly connected.
As optimal technical scheme of the present utility model, the axis of described valve body import is perpendicular to the axis of valve outlet.
As optimal technical scheme of the present utility model, the surface of described spool is provided with wear-resisting carburized case.
As optimal technical scheme of the present utility model, the lower end of described valve bonnet is near the upper surface of valve gap.
As optimal technical scheme of the present utility model, the import of described valve body and outlet are respectively equipped with the flange fillet.
The beneficial effects of the utility model are: with respect to prior art, the upper end of the utility model valve rod is with valve bonnet, impurity etc. are difficult for entering in the screw thread of valve rod, spool is made as taper shape, the surface of contact of spool and body cavity is provided with wear-resisting carburized case, long-term use is not easy to wear yet, thus the working life of having improved the right angle throttle valve.The utility model compact structure, long service life, good sealing effect.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the right angle throttle valve, comprise valve body 1, valve gap 2, valve rod 3 and spool 5, described valve gap 2 is tightly connected with valve body 1 and fixes, and valve gap 2 centers are provided with valve rod 3, and the lower end of valve rod 3 is provided with spool 5, spool 5 is located at the import 11 of valve body and exports between 12, described valve rod 3 is flexibly connected by screw thread with valve gap 2, and valve rod 3 upper ends are provided with valve bonnet 4, and valve bonnet 4 is set on the valve rod 3 and can be with ovable valve stem 3 to rotate; Described spool 5 is made as conical structure, and spool 5 can move up and down with the rotation of valve rod 3, and spool 5 can form the gap that reduces gradually with the sealing surface 6 of valve body 1, until final formation is tightly connected.
In the present embodiment, the axis of described valve body import 11 is perpendicular to the axis of valve outlet 12, and the surface of spool 5 is provided with wear-resisting carburized case.The lower end of the described valve bonnet 4 of present embodiment is near the upper surface of valve gap 2, and import 11 and the outlet 12 of described valve body are respectively equipped with flange fillet 13.
