Description
Technical field
This utility model relates to oxygenerator, is specifically related to the provision for disengagement of a kind of plateau Miniature oxygenerator switching valve.
Background technology
NVACARE plateau Miniature oxygenerator and most of Miniature oxygenerators in structural principle, working method without big difference, its feature is embodied in control circuit, failure code shows and gas circuit switching control aspect, control circuit is based on pressure process programme-control, failure code shows it is also to monitor that pressure process is for foundation, and gas circuit switching control then controls pneumatic element with electromagnetic valve and realizes.
It is secondary that switching valve is formed valve plate by two pieces of dynamic and static ceramic sliding, elapses diverse location with the dynamic valve plate of air cylinder driven, controls the duty of A/B bis-sifting bed air inlet, air vent. Plateau Miniature oxygenerator is in the normal situation of external power source supply, mean free error time is long, even if occurring that machine aspect fault relatively easily solves, if the factors such as air intake filter inefficacy, the poisoning efflorescence of molecular sieve cause dust and dirt residual buildup, between dynamic and static valve plate, resistance is excessive, to such an extent as to drive cylinder the passage of dynamic valve plate to be put in place, cause its duty abnormal. So need dismounting switching valve to carry out care and maintenance when being necessary.
The valve gap of switching valve is fixed by the 3 of trip card-bit parts and 4 screws, first 4 soket head cap screws of dismounting, when tripping 3 card-bit parts, 3 card-bit parts should be protected be released simultaneously, simply can not dial sled trip successively with flat mouth screwdriver, it is easy to damaging parts, a lot of situations are to have pushed 1 card-bit part aside, when dialling the 2nd, the 1st is blocked again. 3 card-bit parts that can be effectively ensured trip with specific purpose tool discussed herein are tripped simultaneously, and safety is pulled down.
Utility model content
The purpose of this utility model is to provide the provision for disengagement of a kind of plateau Miniature oxygenerator switching valve, and the card-bit part being effectively ensured trip is tripped simultaneously.
For reaching above-mentioned purpose, this utility model be the technical scheme is that the provision for disengagement providing a kind of plateau Miniature oxygenerator switching valve, including substrate and the first claw hook being flexibly connected with substrate, the second claw hook and third claw hook; Connecting by transverse slat is fixing between first claw hook and the second claw hook, third claw hook is provided with for by the handle of the fastener pull-up of trip in switching valve.
Preferably, the both sides of substrate one end connect the first claw hook and the second claw hook respectively, and the other end is provided with third claw hook.
Preferably, the first claw hook, the second claw hook and third claw hook are provided with the screw used with screw fit.
Preferably, transverse slat connects by screw and the first claw hook and the second claw hook are fixing.
Preferably, the lower end of transverse slat is provided with for by the transverse slat protuberance of the fastener pull-up of trip in switching valve.
Preferably, handle lower end is provided with the convenient handle protuberance applying pulling force.
Preferably, the first claw hook, the second claw hook and third claw hook are connected with substrate by matching used pin and pin-and-hole.
In sum, this utility model has the advantage that
This utility model passes through the first claw hook, the second claw hook and the third claw hook that are arranged on substrate, and 3 claw hooks are corresponding with the 3 of trip card-bit part positions, wedging little inclined-plane, card-bit part front end, 45 degree of inclined-planes of the pawl point of claw hook, it is forced to move to tripping direction, 3 card-bit parts being effectively ensured trip are tripped simultaneously, and safety is pulled down and portion damages parts.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
In an embodiment of the present utility model, as shown in Figure 1, it is provided that the provision for disengagement of a kind of plateau Miniature oxygenerator switching valve, including substrate 1 and the first claw hook the 2, second claw hook 3 and third claw hook 4 of being flexibly connected with substrate 1; Connecting by transverse slat 5 is fixing between first claw hook 2 and the second claw hook 3, third claw hook 4 is provided with for by the handle 7 of the fastener pull-up of trip in switching valve.
Optimal enforcement example of the present utility model, the both sides of substrate 1 one end connect the first claw hook 2 and the second claw hook 3 respectively, and the other end is provided with third claw hook 4, first claw hook the 2, second claw hook 3 and third claw hook 4 be provided with screw 11 with the use of screw; Transverse slat 5 is fixed by screw 11 be connected with the first claw hook 2 and the second claw hook 3, the lower end of transverse slat 5 is provided with for by the transverse slat protuberance 6 of the fastener pull-up of trip in switching valve, handle 7 lower end is provided with the convenient handle protuberance 8 applying pulling force, first claw hook the 2, second claw hook 3 and third claw hook 4 and is connected with substrate 1 by matching used pin 10 and pin-and-hole 9.
The valve gap of switching valve is fixed by 3 card-bit parts 13 of trip 12 and 4 matching used screws and screw hole 14, first claw hook the 2, second claw hook 3 and third claw hook 4 are mounted on substrate 1, and it is corresponding with the 3 of trip card-bit part 13 positions, when claw hook clasps the card-bit part of trip 12, when exerting oneself to claw hook point direction, wedging little inclined-plane, card-bit part 13 front end, 45 degree of inclined-planes of pawl point, forces it to move to tripping direction, and continuation reinforcing just can smoothly complete to be tripped. 4 soket head cap screws on the valve gap of dismounting switching valve, keeping valve gap upwards, a hands is firmly held valve body and is placed in desktop, and the 3 of provision for disengagement claw hooks are aligned the little inclined-plane of 3 card-bit part 13 front ends by another hands, finger coordination firmly somewhat presses, and pulls up and can conveniently dismantle.
Although detailed description of the invention of the present utility model being described in detail in conjunction with accompanying drawing, but should not be construed as the restriction of the protection domain to this patent. In the scope described by claims, various amendments that those skilled in the art can make without creative work and deformation still belong to the protection domain of this patent.
