图1为本发明原理图，如图所示，它包含端盖（1）、端盖螺栓（9）以及开有流体进口（71）和流体出口（72）的阀体（7），其特征在于：所述的阀体（7）内制有阀体腔（73），阀体腔（73）与流体进口（71）和流体出口（72）相连接，并且阀体腔（73）还与活塞（8）滑动连接；所述的活塞（8）是由隔板（81）、活塞上部（82）和活塞下部（83）所组成；所述的活塞上部（82）通过弹簧（5）与弹簧压盖（3）相连接，弹簧压盖（3）与螺杆（6）和阀体腔（73）相连接，螺杆（6）与端盖（1）相连接；所述的活塞下部（83）上制有活塞孔（84）。 Fig. 1 is a principle diagram of the present invention, as shown in the figure, it includes an end cover (1), an end cover bolt (9) and a valve body (7) with a fluid inlet (71) and a fluid outlet (72). It is: the valve body (7) is made with a valve body cavity (73), the valve body cavity (73) is connected with the fluid inlet (71) and the fluid outlet (72), and the valve body cavity (73) is also connected with the piston (8 ) sliding connection; the piston (8) is composed of a partition (81), the upper part of the piston (82) and the lower part of the piston (83); the upper part of the piston (82) is connected to the spring cover by the spring (5) (3) are connected, the spring gland (3) is connected with the screw rod (6) and the valve body cavity (73), and the screw rod (6) is connected with the end cover (1); the lower part of the piston (83) is formed with Piston bore (84).

本发明中所述的弹簧压盖（3）是采用弹性圆柱销（4）定位在阀体腔（73）内。 The spring gland (3) described in the present invention is positioned in the valve body cavity (73) by elastic cylindrical pins (4).

本发明中所述的螺杆（6）是采用螺母（10）和螺帽（11）固定的。 The screw rod (6) described in the present invention is fixed by a nut (10) and a nut (11).

本发明的工作原理是：工作时流体由流体进口（71）流入阀体（7）内，随着流体进口（71）处流体压力的增大，推动活塞（8）在阀体（7）内移动。当流体的压力大于弹簧（5）的压力后就会推动活塞（8）向上运动，活塞（8）运动一定距离后就会使流体通过活塞（8）上的活塞孔（84）、流体出口（72）流出，达到泄压的作用。 The working principle of the present invention is: when working, the fluid flows into the valve body (7) from the fluid inlet (71), and as the fluid pressure at the fluid inlet (71) increases, the piston (8) is pushed into the valve body (7) move. When the pressure of the fluid is greater than the pressure of the spring (5), it will push the piston (8) to move upward, and after the piston (8) moves a certain distance, the fluid will pass through the piston hole (84) on the piston (8), the fluid outlet ( 72) flow out to achieve the effect of pressure relief.

由于活塞（8）在阀体（7）内移动时泄压流量随着活塞（8）移动而缓慢增大，所以泄压时不会出现突然开启的冲击。 Since the pressure relief flow increases slowly with the movement of the piston (8) when the piston (8) moves in the valve body (7), there will be no sudden opening impact during pressure relief.

当需要改变流体进口（71）和流体出口（72）处的流体压差时，可以通过旋转螺杆（6）调节弹簧压盖（3）在螺杆（6）上的位置，即可改变弹簧（5）的弹力，并达到调节流体进口（71）和流体出口（72）处流体压差的目的。 When it is necessary to change the fluid pressure difference between the fluid inlet (71) and the fluid outlet (72), the position of the spring gland (3) on the screw (6) can be adjusted by rotating the screw (6), and the spring (5) can be changed. ), and achieve the purpose of adjusting the fluid pressure difference at the fluid inlet (71) and the fluid outlet (72).

此外，本发明由于泄压方式是通过活塞（8）上的活塞孔（84）缓慢泄压的，因此，流体进口（71）的流体压力越大活塞（8）对弹簧（5）的压力也就越大，活塞（8）上的活塞孔（84）和流体出口（72）相通的面积就会越大，泄压能力就越强。 In addition, because the pressure relief method of the present invention is to release pressure slowly through the piston hole (84) on the piston (8), the greater the fluid pressure at the fluid inlet (71), the greater the pressure of the piston (8) on the spring (5). The bigger it is, the bigger the area that the piston hole (84) on the piston (8) communicates with the fluid outlet (72) will be, and the pressure relief capability will be stronger.
