Abstract

The invention belongs to the technical field of utensils of air detectors, and particularly relates to a novel valve of an air detector. The novel valve of the air detector comprises a valve body; a cavity is arranged in the valve body, and a spring is fixed into the cavity; a valve channel which is communicated with the cavity is arranged at one end of the valve body, a valve stem is arranged in the valve channel, a gap is reserved between the valve stem and the valve channel, the front end of the valve stem extends into the cavity to be connected with the spring, a stopper capable of sealing the valve channel is arranged at the front end of the valve stem, and the rear end of the valve stem extends out of the valve body; and an air inlet which is communicated with the cavity is arranged on the upper portion of the valve body, and an air outlet which is communicated with the valve channel is arranged on the lower portion of the valve body. The novel valve has the advantage that an air inlet procedure and an air outlet procedure of the air detector are integrated, so that the integral air detector is simplified and is convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of gas detector appliances, in particular to a novel gas detector valve. Background technique [0002] Disposable intravenous infusion needles are commonly used infusion equipment in hospitals. Disposable intravenous infusions have certain requirements for their tightness and smoothness of pipelines and needles. And at present, when producing disposable use intravenous infusion needle, all adopt manual operation for the general method of its detection. Moreover, when checking its airtightness and checking whether the intravenous infusion needle pipeline and the needle are unimpeded, the detection test is carried out separately. As a result, the entire detection process takes a long time, and two processes need to be performed, which is troublesome for the entire detection process and is prone to errors. Moreover, it is easy to cause damage or secondary pollution to the disposable intravenous infusion needl...
