Abstract
The utility model relates to a novel check valve of a vortex air compressor, which comprises a sleeve-shaped valve body and a sleeve-shaped air outlet joint. The valve body is sleeved in the air outlet joint. The lower end of the air outlet joint is provided with an air outlet. An inner cavity of the valve body is communicated with an inner cavity of the air outlet joint. A sealing device is arranged in the inner cavity of the valve body. The valve body is also provided with a transition joint which is integrated with the valve body into one whole body. An inner cavity of the transition joint is communicated with the inner cavity of the valve body. The transition joint and the valve body are die-cast into one whole body, so that fittings of the transition joint are reduced, thus, not only is the problem of air leakage easily generated when the transition joint is connected with the check valve solved, but also an air inlet valve has more attractive appearance, the cost of manufacturing materials is reduced, the novel check valve is beneficial to overall layout of the compressor, the installing space is saved, and the novel check valve is convenient to maintain and repair in the future.
Description
(1) technical field
The utility model relates to a kind of one-way valve of scroll type air compressor.
(2) background technique
As novel scroll formula air compressor, it has novel structure, volume is little, in light weight, the low life-span of noise is long, the gas transmission stable and continuous, easy and simple to handle, the technical performance of a series of excellences such as maintenance expense province is described as " need not to keep in repair air compressor " and " new revolution air compressor " in the industry.It also is quite high to outward appearance, the performance demands of each parts for the compressor of this pattern, and one-way valve is the indispensable important component part of compressor, and the quality of its function directly influences the usability of compressor.The one-way valve of existing scroll type air compressor is just can be connected on the pipeline of compressor assembly through several crossover subs in the installation of complete machine, tie point is prone to the problem of gas leakage, whole pipe-line system is numerous and diverse, big to the connection space claimed range, be unfavorable for the mounting arrangement of compressor complete machine.
In addition, the seal form of existing one-way valve is an O type circle, because the sectional area ratio of O type circle is less, sealability is relatively poor.
In addition, the structure of the spring sealing that existing one-way valve adopts is because the high working efficiency of this one-way valve has reduced the working life of one-way valve thereby spring is ruptured sometimes at high-frequency work lower spring.
(3) summary of the invention
For the one-way valve that overcomes existing scroll type air compressor need pass through the deficiency that several crossover subs could be connected with the compressor assembly pipeline, the utility model provides a kind of one-way valve that need not the scroll type air compressor of several crossover subs.
Further, the utility model provides a kind of one-way valve that adopts the better scroll type air compressor of sealability of sealing gasket.
Further, the utility model provides a kind of one-way valve of scroll type air compressor of inapplicable spring.
The technical scheme in the invention for solving the technical problem is: a kind of one-way valve of novel scroll formula air compressor, comprise the valve body of sleeve shape and the air outlet adapter of sleeve shape, described valve body is placed in the described air outlet adapter, described air outlet adapter lower end is the air outlet, the inner chamber UNICOM of the inner chamber of described valve body and described air outlet adapter, be provided with seal arrangement in the inner chamber of described valve body, also be provided with and its all-in-one-piece transit joint the inner chamber UNICOM of the inner chamber of described transit joint and described valve body on the described valve body.
Further, the end of the head end of described transit joint and described air outlet adapter is provided with outside thread.
Further, offer the linked hole of the inner chamber of the inner chamber of the described valve body of UNICOM and air outlet adapter on the sidewall of described valve body; The inwall of the valve body of described linked hole top is provided with the inwardly protruded step back-up ring of a circle, and there is the sealing gasket of the inner chamber of salable described valve body the below of described step back-up ring; Be provided with the support structure that is used to accept described sealing gasket in the valve body of described sealing gasket below.
Further, cross a bearing pin in the valve body of described sealing gasket below, be equipped with the valve seat that is positioned at described valve body on the described bearing pin.
The utility model is connected with the pipe-line system of compressor by transit joint in use, adopts the form of die casting to form one between transit joint and the valve body, from the end air inlet of transit joint.Under the situation that compressor operating loads, the pressure that can overcome system self medium along with the rising suction pressure of pressure is easily opened one-way valve, allow pressurized air pass through one-way valve rapidly, and work as under the out-of-work situation of compressor because inlet end does not have the generation of air pressure, and the also in store certain interior pressure of system self at this moment, at this moment one-way valve just utilizes this pressure to withstand sealing gasket itself and step back-up ring are fitted tightly, throttle down, the anti-aerogenesis head that flows to compression of pressure in the anti-locking system.
The beneficial effects of the utility model are: 1. adopt transit joint and valve body to be cast into one, reduced the accessory of transition jointing, not only well solve transit joint and be connected the problem that is prone to gas leakage with one-way valve, make the profile of suction valve more attractive in appearance, reduced the cost of manufactured materials, be beneficial to the complete machine layout of compressor, save installing space, be convenient in the future maintenance and maintenance.2. the end of the head end of transit joint and air outlet adapter is provided with outside thread, and employing is threaded, and is simple in structure, and volume is less, is convenient in the future maintenance and maintenance.3. adopt sealing gasket to seal, sealing surface increases, and makes the sealability of valve stable, reliable.4. spring has been omitted in the below of sealing gasket, can improve the shelf life of valve.
