Background

The multi-way valve is a valve body for switching air flows of a plurality of channels as shown in figure 1, the tightness detection of the valve body is a necessary item before leaving a factory, the detection of the valve body in the prior art is realized by manually ventilating air inlets 1-7, then switching spherical valve cores 1-8, installing air bags at each air outlet and observing the change of the air bags, the detection mode has low precision, the air bags have small change to the pipelines with trace air leakage, so that the air leakage phenomenon is difficult to observe, and due to the structural particularity of the valve body, one worker is required to centralize the valve body, the other worker is required to operate a valve handle 1-1 and observe the change of the air bags, and the inspection of one valve body can be completed by using two persons.

Disclosure of Invention

To the problem, the utility model discloses a valve body gas tightness detects frock, this frock adopt the fixed mode of cylinder, observe the change state in every passageway through the manometer, and convenient operation saves the manual work, and it is high to detect the precision.

The utility model provides a valve body gas tightness detects frock, includes the base, the upper surface of base is provided with a plurality of cylinders that are used for pressing from both sides tight valve body, install the air pump in the base, the air inlet intercommunication of air pump and valve body, an air outlet channel is all connected to every gas outlet of valve body, and every air outlet channel all disposes the manometer.

Preferably, the air outlet channel is connected with the air outlet through a clamping hoop.

Preferably, the number of the cylinders is three, and the three cylinders are uniformly arranged in the circumferential direction.

Preferably, the inner diameter of the tail end of the air outlet channel is larger than the inner diameter of the air outlet.

Preferably, the end opening of the air outlet channel is arranged downwards.

Preferably, a silencer is arranged at the tail end of the air outlet channel.

The utility model has the advantages that:

1. the utility model discloses a mode that the cylinder is fixed observes the change state in every passageway through the manometer, and convenient operation saves the manual work, and it is high to detect the precision.

2. The three cylinders clamp the valve body, and the valve body is centered and clamped by utilizing the three-point centering principle.

3. The opening of the air outlet channel is downward, so that the air flow can not directly face people in the detection process, and personal injury is avoided.
