Preferably, valve chamber and air guide channel are offered in the piston, the air guide channel is from the piston towards institute
The end face for stating cylinder head is penetrated through into the valve chamber；The valve member includes:
Spool is set in the valve chamber and can slide along the valve chamber；
Second spring is set in the valve chamber for pushing against the spool towards the tail portion of the cylinder；Wherein:
When the pressure for the gas being passed through in the cylinder is greater than the preset pressure, the gas pushes against the spool court
The head of the cylinder is slided, so that the air guide channel is opened and makes the gas of part by the air guide channel, and is passed through
Gap outflow between the cylinder head and the cutter.
Preferably, baffle ring is provided in the cylinder, the baffle ring is for piston described in backstop.
Compared with prior art, the beneficial effect of the disconnecting device of the utility model is: the utility model passes through in piston
Upper setting valve member makes cutter be unlikely to because excessive to be damaged against power by backstop wall surface.

Specific embodiment
It is with reference to the accompanying drawing and specific real to make those skilled in the art better understand the technical solution of the utility model
Mode is applied to elaborate to the utility model.
As depicted in figs. 1 and 2, the embodiments of the present invention disclose a kind of disconnecting device, for cutting off adjacent two
The coupling part 100 of a moulding, comprising: cylinder 10, piston 20, the first spring 40 and valve member.10 tail portion of cylinder is used for
It is connect with tracheae；Piston 20 is set in cylinder 10, and can be slided along cylinder 10；First spring 40 is set to the head of cylinder 10
Between portion and piston 20；30 tail portion of cutter is connected to piston 20, the head of head stretches out cylinder 10；Valve member is set to piston
In 20, and when the pressure for the gas being passed through in cylinder 10 by tracheae is greater than preset pressure, valve member conducting, so that part gas
Body is flowed out by piston 20 from the head of cylinder 10.Specifically, valve chamber 21 and air guide channel 22, air guide are offered in piston 20
Channel 22 is penetrated through from piston 20 towards the end face on 10 head of cylinder into valve chamber 21；Valve member includes: spool 51 and the second bullet
Spring 52.Spool 51 is set in valve chamber 21 and can slide along valve chamber 21；Second spring 52 is set in valve chamber 21 for court
The tail portion of cylinder 10 pushes against spool 51；Wherein: when the pressure for the gas being passed through in cylinder 10 is greater than preset pressure, gas pushing and pressing
Spool 51 is slided towards the head of cylinder 10, so that air guide channel 22 is opened and makes the gas of part by air guide channel 22, and is led to
Cross the outflow of the gap between 10 head of cylinder and cutter 30.Baffle ring 60 is provided in cylinder 10, baffle ring 60 is used for backstop
Piston 20.
The process of the coupling part 100 of two mouldings of cutting of disconnecting device above-mentioned is described below:
Firstly, as shown in figure 3, cutter 30 is made to keep vertical with coupling part 100, using tracheae to the tail portion of cylinder 10
Logical pressed gas, so that cutter 30 cuts off coupling part 100.
When the head of cutter 30 is against to stop wall face 101, if tracheae still continues to be passed through gas to cylinder 10 and cause
Gas pressure is more than preset pressure in cylinder 10, and when will lead to the head of cutter 30 by excessively high pressure damage, such as Fig. 4 and
Shown in Fig. 5, spool 51 slides under the influence of air pressure and towards the head of cylinder 10, so that air guide channel 22 is opened, at this point,
Portion gas in cylinder 10 enters valve chamber 21, and the gap stream via air guide channel 22 and between cutter 30 and cylinder 10
Out, and then make the pressure reduction of cylinder 10, or the pressure in cylinder 10 is made to maintain a constant pressure value always.
Should illustrate: preset pressure need to be arranged to be unlikely to so that within the impaired pressure in the head of cutter 30, and pre-
If the setting of pressure is determined by the decrement and coefficient of elasticity of second spring 52.
Above embodiments are only the exemplary embodiment of the utility model, are not used in limitation the utility model, this is practical new
The protection scope of type is defined by the claims.Those skilled in the art can be in the essence and protection scope of the utility model
It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling in originally practical new
In the protection scope of type.
