[0002] In the prior art, a decompression spring is placed in the cavity of the pressure stabilizing valve to adjust the position of the valve core. When the inlet pressure of the pressure stabilizing valve is greater than the set pressure of the decompression spring, the decompression spring is under pressure to adjust the position of the spool , so that the outlet pressure of the regulator valve is balanced with the spring pressure to achieve the purpose of voltage stabilization, but when the inlet pressure is less than the set pressure, the decompression spring also has a certain decompression effect, resulting in a certain resistance, so that the outlet pressure is lower than the inlet pressure , limiting the use of certain

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] see figure 1 , the novel fluid pressure stabilizing valve, is characterized in that, comprises the valve body 1 that is provided with the inlet 11 that communicates with each other, outlet 12 and valve body cavity 13; There is a pressure guide hole 141 communicating with the valve body cavity 13, and the tail end communicates with the outlet 12; the valve body 1 is provided with a pressure stabilizing device for adjusting the opening of the pressure guide hole 141. When the outlet pressure is lower or higher than the set pressure, the outlet pressure is still kept constant through the adjustment of the pressure stabilizing device.

[0019] The pressure stabilizing device includes a stabilizing chamber 31 with an adjustable volume, a valve stem 51 and a valve core 52; the valve stem 51 is movably arranged on the valve body 1, and its head extends...

Abstract

A novel fluid pressure stabilizing valve comprises a valve body provided with an inlet, an outlet and a valve body cavity, and the inlet, the outlet and the valve body cavity communicate with one another. The valve body cavity is internally provided with a pressure stabilizing pipe. The head end of the pressure stabilizing pipe is provided with a pressure guiding hole communicating with the valve body cavity, and the tail end of the pressure stabilizing pipe communicates with the outlet. The valve body is provided with a pressure stabilizing device for adjusting the open degree of the pressure guiding hole. According to the novel fluid pressure stabilizing valve, when the outlet pressure is higher or lower than the set pressure, the pressure stabilizing device conducts dynamic adjusting along with the change of the outlet pressure, so that the outlet pressure is kept constant; and the valve body cavity serves as a buffering cavity and achieves the effects of auxiliary adjusting and buffering when the pressure stabilizing device conducts adjusting, the adjusting effect is further optimized, and the outlet pressure is more constant.

Description

technical field [0001] The invention relates to a novel fluid pressure stabilizing valve. Background technique [0002] In the prior art, a decompression spring is placed in the cavity of the pressure stabilizing valve to adjust the position of the valve core. When the inlet pressure of the pressure stabilizing valve is greater than the set pressure of the decompression spring, the decompression spring is under pressure to adjust the position of the spool , so that the outlet pressure of the regulator valve is balanced with the spring pressure to achieve the purpose of voltage stabilization, but when the inlet pressure is less than the set pressure, the decompression spring also has a certain decompression effect, resulting in a certain resistance, so that the outlet pressure is lower than the inlet pressure , limiting certain usage scenarios. [0003] Therefore, further improvements are required. Contents of the invention [0004] The purpose of the present invention is...
