Abstract

The utility model belongs to a rod-core integrated conical-surface valve. The technical scheme includes that the conical-surface valve comprises a fixed nut (1), a handle (2) and a valve body (5) with an inlet (6) and an outlet (7). The conical-surface valve is characterized in that a valve rod end (34) of a valve rod (3) with a valve core is connected with the fixed nut (1) and the handle (2), a conical-surface valve core end (33) of the valve rod (3) with the valve core is connected with the inlet (6) and the outlet (7) in the valve body (5), and a valve core fluid hole (31) is arranged on the conical-surface valve core end (33). The valve rod (3) with the valve core is a component enabling the valve rod end (34) and the conical-surface valve core end (33) to be integrally formed. The rod-core integrated conical-surface valve has the advantages that cone-shaped design is adopted between the valve core end and the valve body, and due to the fact that the conical-surface valve core end can utilize fluid pressure to reinforce sealing performance between the valve core end and the valve body, the rod-core integrated conical-surface valve has the function of automatically avoiding leakage and is durable.

Description

The incorporate conical valve of a kind of bar core

Technical field

The F16K5/00 that the utility model relates on the International Classification of Patents (IPC) only comprises the tap of shut-off means or the classification of cock, especially belongs to the incorporate conical valve of a kind of bar core.

Background technique

Between traditional spool and the valve body generally is not that the conical surface contacts, and therefore, uses a period of time to occur sealability easily and descends, and the situation that valve leaks has influenced normal use.

Summary of the invention

The purpose of the utility model is to provide a kind of bar core incorporate conical valve, can overcome bad connection between traditional spool and the valve body to reach, and causes the problem that is prone to leak, and can reach simple in structure again, long-lived effect.

The technological scheme that the utility model is taked is: it comprises hold-doun nut (1), handle (2), has the valve body (5) of import (6) and outlet (7); It is characterized in that: the valve rod end (34) of the valve rod of belt spool (3) links to each other with hold-doun nut (1), handle (2); The conical surface spool end (33) of the valve rod of belt spool (3) links to each other with outlet (7) with the interior import (6) of valve body (5), and on conical surface spool end (33), is shaped on spool fluid bore (31); Wherein, the valve rod of described belt spool (3) is meant the parts of valve rod end (34) and conical surface spool end (33) being processed one.

The beneficial effect of the utility model is: 1, the utility model adopts conical design between spool end and valve body; Because conical surface spool end can utilize hydrodynamic pressure to strengthen the sealability of spool end and valve body; Therefore, have the function of automatically anti-heads, durable in use; 2, the utility model makes that the sealing of valve rod end and valve body is reliable, performance is good owing to adopt the incorporate design of bar core, is fit to from low pressure to the high pressure and the use of various abominable occasions.

Description of drawings

Fig. 1 is the utility model schematic diagram

wherein: 1, the valve rod 31 of hold-doun nut 2, handle 3, belt spool, spool fluid bore 32, fluid bore axle center 33, conical surface spool end 34, valve rod end 4, butterfly spring 5, valve body 6, import 7, outlet 71, valve outlet face.

Embodiment

are described further the utility model below in conjunction with accompanying drawing.

are illustrated in figure 1 as the utility model schematic diagram; The utility model as shown in the figure comprises hold-doun nut (1), handle (2), has the valve body (5) of import (6) and outlet (7); It is characterized in that: the valve rod end (34) of the valve rod of belt spool (3) links to each other with hold-doun nut (1), handle (2); The conical surface spool end (33) of the valve rod of belt spool (3) links to each other with outlet (7) with the interior import (6) of valve body (5), and on conical surface spool end (33), is shaped on spool fluid bore (31); Wherein, the valve rod of described belt spool (3) is meant the parts of valve rod end (34) and conical surface spool end (33) being processed one.

Fluid bore axle center (32) on the spool fluid bore (31) described in the utility model also can be processed orthogonal with the valve outlet face (71) in the valve body (5).The effect of using like this will be better.

Claims
