Abstract

The utility model relates to the field of pipeline facilities, in particular to a valve capable of locking position, which comprises a valve shell, a spherical valve core and a rotary handle, wherein the spherical valve core is arranged in the valve shell, and the rotary handle is arranged at the top of the valve shell and connected with the spherical valve core; the valve capable of locking position is characterized by further comprising a inserted link; at least four through holes are arranged at the top of the valve shell and evenly distributed, the center of the circle of the four through holes are on the same circle, the axial lead of the circle and the axial lead of the spherical valve core are on the same axis, and the diameter of the circle is smaller than the sphere diameter of the spherical valve core; a blind hole matched with the top of the valve shell is arranged at the top of the spherical valve core; and the diameters of the through holes at the top of the valve shell and the blind hole at the top of the spherical valve core matches with the diameter of the inserted link.

Description

But the valve of lock-bit

Technical field

The utility model relates to the piping facility field, but is specially a kind of valve of lock-bit.

Background technique

Existing service water pipe valves mostly are the valves of spherical valve core, adopt the switch degree of handle rotary control valve door, owing to there is not the fixedly mechanism of handle, usually change the switch degree of valve, change the size of current, make troubles for the daily life water because the mistake of external force is bumped.

Summary of the invention

The purpose of this utility model is to overcome the defective of existing water pipe valves, but but provides a kind of valves of lock-bit of fixed spool switch degree.

In order to achieve the above object, but the utility model is achieved in that a kind of valve of lock-bit, and it comprises valve casing, spherical valve core, handle, and spherical valve core is located in the valve casing, and handle is located at the valve casing top and is linked to each other with spherical valve core; It is characterized in that: further comprising inserted link; The valve casing top has at least four through holes, and the center of circle of four through holes is positioned on the same circle and evenly and distributes, and the shaft axis of described circle and the shaft axis of spherical valve core are on the same axis, and diameter of a circle is less than the sphere diameter of spherical valve core; The top of spherical valve core has the blind hole that is complementary with the valve casing top; The diameter of the blind hole at the through hole at valve casing top, spherical valve core top all with the diameter of inserted link coupling.

The utility model adopts above-mentioned design, and after valve reached suitable angle, just available inserted link was inserted in the through hole and blind hole of valve casing, spool, so, makes spool can not guarantee the stability of water flow because of external force changes the switch degree.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Below further specify the utility model by specific embodiment.

As shown in Figure 1, but a kind of valve of lock-bit, it comprises valve casing 1, spherical valve core 2, handle 3, and spherical valve core 2 is located in the valve casing 1, and handle 3 is located at valve casing 1 top and is linked to each other with spherical valve core 2; It is characterized in that: further comprising inserted link 4; Valve casing 1 top has at least four through holes, and the center of circle of four through holes is positioned on the same circle and evenly and distributes, and the shaft axis of the shaft axis of described circle and spherical valve core 2 is on the same axis, and diameter of a circle is less than the sphere diameter of spherical valve core 2; The top of spherical valve core 2 has the blind hole that is complementary with valve casing 1 top; The diameter of the blind hole at the through hole at valve casing 1 top, spherical valve core 2 tops all with the diameter of inserted link 4 coupling.

The utility model is after spherical valve core 2 reaches suitable angle, and just available inserted link 4 is inserted in the through hole and blind hole of valve casing 1, spherical valve core 2, so, makes spherical valve core 2 can not guarantee the stability of water flow because of external force changes the switch degree.

Claims

But 1. the valve of a lock-bit, it comprises valve casing, spherical valve core, handle, and spherical valve core is located in the valve casing, and handle is located at the valve casing top and is linked to each other with spherical valve core; It is characterized in that: further comprising inserted link; The valve casing top has at least four through holes, and the center of circle of four through holes is positioned on the same circle and evenly and distributes, and the shaft axis of described circle and the shaft axis of spherical valve core are on the same axis, and diameter of a circle is less than the sphere diameter of spherical valve core; The top of spherical valve core has the blind hole that is complementary with the valve casing top; The diameter of the blind hole at the through hole at valve casing top, spherical valve core top all with the diameter of inserted link coupling.
