Abstract

The invention discloses a direct-acting overflow valve. The direct-acting overflow valve comprises a valve body (2), a valve core (3), a valve cover (4), a pressure adjusting screw (5), a spring seat (6) and a spring (7), wherein the valve core (3) is arranged in the valve body (2), the valve cover (4) is arranged on the valve body (2), the spring seat (6) is arranged in a valve cavity of the valve body (2), the spring (7) is connected between the spring seat (6) and the valve core (3), and the pressure adjusting screw (5) is connected with the spring seat (6) by penetrating through the valve cover (4). According to the direct-acting overflow valve disclosed by the invention, when the valve core is opened, the opening of the valve core can be smooth and stable due to a damping function of a damping hole of the valve core, the stability performance is good, and no vibration and noise are generated.

Description

Direct-acting overflow valve
Technical field
The present invention relates to a kind of direct-acting overflow valve.
Background technique
Existing direct-acting overflow valve, when the flow of flow increases, can cause spool unstability, produces spool flowing water inequality around, thereby causes the generation of noise.
Summary of the invention
The object of this invention is to provide a kind of direct-acting overflow valve.
The technological scheme that the present invention adopted is for achieving the above object: a kind of direct-acting overflow valve, comprise valve body (2), spool (3), valve gap (4), pressure regulating screw (5), spring seat (6) and spring (7), spool (3) is arranged in valve body (2), valve gap (4) is arranged on valve body (2), spring seat (6) is arranged in the valve pocket of valve body (2), spring (7) is connected between spring seat (6) and spool (3), and pressure regulating screw (5) is connected with spring seat (6) through valve gap (4).
Between described valve body (2) and spool (3), be provided with damping hole (1).
A kind of direct-acting overflow valve of the present invention, in the time that spool is opened, due to the damping function of the damping hole of spool, opens spool steady, and stability is good, friction and noise.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of direct-acting overflow valve of the present invention.
In figure: 1, damping hole; 2, valve body; 3, spool; 4, valve gap; 5, pressure regulating screw; 6, spring seat; 7, spring.
Embodiment
As shown in Figure 1, direct-acting overflow valve, comprise valve body (2), spool (3), valve gap (4), pressure regulating screw (5), spring seat (6) and spring (7), spool (3) is arranged in valve body (2), valve gap (4) is arranged on valve body (2), spring seat (6) is arranged in the valve pocket of valve body (2), spring (7) is connected between spring seat (6) and spool (3), pressure regulating screw (5) is connected with spring seat (6) through valve gap (4), between valve body (2) and spool (3), be provided with damping hole (1), in the time that the flow of the valve of flowing through changes, the position of spool also will change, but in the time of changes in flow rate, spool moves seldom, therefore can think that valve port is once opening, it is invariable that the pressure of relief valve ingress keeps substantially, in the time that system pressure raises, on spool, move, valve port place resistance is reduced, and then system pressure reduces, system pressure remains unchanged substantially, direct-acting overflow valve of the present invention, in the time that spool is opened, due to the damping function of the damping hole of spool, spool is opened steadily, stability is good, friction and noise.

Claims (2)

1. a direct-acting overflow valve, it is characterized in that: comprise valve body (2), spool (3), valve gap (4), pressure regulating screw (5), spring seat (6) and spring (7), spool (3) is arranged in valve body (2), valve gap (4) is arranged on valve body (2), spring seat (6) is arranged in the valve pocket of valve body (2), spring (7) is connected between spring seat (6) and spool (3), and pressure regulating screw (5) is connected with spring seat (6) through valve gap (4).
2. a kind of direct-acting overflow valve according to claim 1, is characterized in that: between described valve body (2) and spool (3), be provided with damping hole (1).
