Abstract
The utility model discloses a check valve. The check valve comprises a valve body, wherein a connector hole which is connected with a copper pipe is arranged on the valve body, the end of the connector hole is an outer conical surface, and an annular outer convex rib is formed on the outer conical surface of the end of the connector hole. The check valve can overcome the defects in the prior art, and on the premise that the same sealing effect is achieved, the locking torque is small, consumption of copper materials is reduced, and production cost is reduced.
Description
Technical field
The utility model relates to the component in air-conditioning system, especially relates to a kind of stop valve.
Background technique
At present, we are at the stop valve being commercially available, and the nipple orifice end on it is a male cone (strobilus masculinus), because the area of its conical surface is larger, therefore causes the pressure in the time being closely connected with copper pipe inner conical surface less, thereby need very large locking torque.Such consequence is exactly the intensity that needs outside thread and the connector post itself of connector post, and the intensity of locking copper screw cap is all higher, so will size larger, copper consumption be relatively large, and cost is higher, haves much room for improvement.
Model utility content
The purpose of this utility model is to provide a kind of stop valve, can solve deficiency of the prior art, in the time reaching the sealing effect being equal to, realizes locking torque little, reduces copper material consumption and cost of production.
To achieve these goals, the technical solution of the utility model is as follows:
Stop valve, comprises valve body, is provided with the nipple orifice being connected with copper pipe on valve body, it is characterized in that: the end of described nipple orifice is male cone (strobilus masculinus), forms one annular outer muscle on the male cone (strobilus masculinus) of described end.
Further, the height of described annular outer muscle is less than or equal to 2 millimeters.
The beneficial effects of the utility model: the utility model adds the stiffening rib slightly protruding together on the end of nipple orifice, so just original plane-plane contact sealing can be made into the sealing of line face, because the pressure of plane-plane contact sealing is little, just need larger locking torque just can reach sealing effect, described improvement of the present utility model, realize sealing local pressure very large, therefore only need less locking torque just can reach the effect of sealing.Therefore region of interest and parts just do not need higher intensity.So in having met sealing effect better, the manufacturing dimension that reduces nipple orifice post, joint screw thread and locking copper cap that just can be suitable, thus the consumption of minimizing copper material that can be larger reduces production costs.
In addition, the annular outer muscle in the utility model, shape of cross section can be circular, can be also oval, can be also semicircle or arc, not limited.
The beneficial effects of the utility model: the utility model, in the time reaching the sealing effect being equal to, is realized locking torque little, reduce copper material consumption and cost of production.
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model relates to a kind of stop valve, comprise valve body 1, on valve body 1, be provided with the nipple orifice 2 being connected with copper pipe, it is characterized in that: the end 3 of described nipple orifice 2 is male cone (strobilus masculinus), on 3 male cone (strobilus masculinus)s of described end, form annular outer muscle 4 one, the height of described annular outer muscle 4 is less than or equal to 2 millimeters.。
The utility model, in the time reaching better sealing effect, is realized locking torque little a lot, and therefore region of interest and parts just do not need higher intensity.So in having met sealing effect better, the manufacturing dimension that reduces nipple orifice post, joint screw thread and locking copper cap that just can be suitable, thus the consumption of minimizing copper material that can be to a certain degree reduces production costs.
The foregoing is only an embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
