Abstract
The utility model discloses a one-way non-return pipe joint product, and overcomes the defects of high cost, large volume and low non-return reliability in the prior art. The one-way non-return pipe joint comprises a body having a port part with outer threads, as well as a locknut, a connection tube and a lock sleeve which are screwed onto the other end of the body; the body is provided with a non-return seat screwed relative to an inner chamber at the other end of the locknut; a cylindrical container is arranged at the upper end of the non-return seat; a steel ball is arranged in the cylindrical container; a spring is arranged between the steel ball and the bottom of the cylindrical container; a vent valve port is formed on the inner cavity of the body adjacent to the steel ball; an air passage is formed in the axial direction of the peripheral wall of the non-return seat and used for communicating the valve port with the lower port of the body; a sealing gasket is arranged between the valve port and the steel ball; and a bushing is arranged on the lower end surface of the sealing gasket and is connected with the top of the non-return seat. The utility model has the advantages of compact outline structure, good reasonability, low cost and the like, and can meet the requirement of installation of matched air compressors.
Description
Technical field
The utility model relates to a kind of pneumatic components and parts manufacturing technology field, the especially unidirectional check device structure technology of vial joint inner chamber.
Background technique
Air compressor is a kind of very common compressed gas source, can be widely used in small business or outdoor pneumatic operation.During work, it is stored in pipe fitting is delivered to gas tank earlier after producing pressurized air by compressed pneumatic pump, and then by gas tank via high-pressure rubber pipe to all kinds of Pneumatic component air feed.Owing to be subjected to the restriction of working environment, particularly during operation in the open air, run into situations such as interim outage through regular meeting, do not reflux in order to ensure the pressurized air in the gas tank and leak this moment, also need an one way stop peturn valve be installed at the gas tank interface; The mounting type of this one way stop peturn valve connecting tube joint not only makes cost of material rise greatly, and overall volume increases, the non-return unfailing performance reduces.For this reason, people expect to invent and a kind ofly collect the unidirectional non-return pipe joint product that unidirectional check function and pipe fitting be connected and installed in one and come out, to overcome prior art cost height, overall volume is big, the non-return reliability is low defective and deficiency.
The model utility content
The technical problems to be solved in the utility model is to overcome defective and the deficiency that prior art products cost height, overall volume are big, the non-return reliability is low, provide a kind of unidirectional non-return pipe joint product that unidirectional check function and pipe fitting are connected and installed in one that collects to society, required with the supporting installation of satisfying the air compressor product.
The technological scheme that its technical problem that solves the utility model adopts is: unidirectional non-return pipe joint comprises the externally threaded body of joining part tool, the other end of described body is connected with locking nut, adapter and lock tube, and described body is connected with the non-return seat at the other end inner chamber with respect to described locking nut; Described non-return seat upper end is provided with the cylinder cavity volume, is provided with steel ball in the described cylinder cavity volume, is provided with spring between described steel ball and the described cylinder cavity volume bottom; Described body is provided with the ventilation valve port at the inner chamber adjacent with described steel ball; The perisporium of described non-return seat is provided with air flue vertically, and described air flue is connected described valve port with described body lower end mouth.
Be provided with sealing gasket between described valve port and the described steel ball, described sealing gasket lower end surface is provided with lining; Described non-return seat top is connected with described lining.
The non-return seat that the unidirectional non-return pipe joint of the utility model spins and accommodates steel ball, spring in chamber body, in case when running into interim outage or mechanical failure, take over internal air pressure and reduce suddenly, this moment spring fast bounce-back make steel ball moment block valve port, can realize unidirectional check function.Compare than prior art products, this product has form structure compactness, good reliability, plurality of advantages such as with low cost, and the supporting installation of gas tank that can satisfy the air compressor product is required.
Description of drawings
Fig. 1 is the utility model product structure schematic representation.
Fig. 2 is that the A-A of Fig. 1 is to the cross section structure schematic representation.
Embodiment
As shown in Figure 1, the unidirectional non-return pipe joint of the utility model, the body 1 that comprises joining part tool outside thread 4, the other end of described body 1 is connected with locking nut 2, described locking nut 2 inner chambers are provided with takes over 5, be provided with lock tube 3 between described adapter 5 outer walls and described locking nut 2 inner chambers, aforementioned locking nut 2, take over 5, lock tube 3 adopts existing known technology with the Placement of body 1, repeated description not in present patent application.Described body 1 is connected with non-return seat 12 at the other end inner chamber with respect to described locking nut 2, and described non-return seat 12 upper ends are provided with cylinder cavity volume 11, are provided with steel ball 7 in the described cylinder cavity volume 11, is provided with spring 10 between described steel ball 7 and described cylinder cavity volume 11 bottoms; Described body 1 is provided with ventilation valve port 6 at the inner chamber adjacent with described steel ball 7, is provided with sealing gasket 8 between described valve port 6 and the described steel ball 7, and described sealing gasket 8 lower end surfaces are provided with lining 9, and described non-return seat 12 tops are connected with described lining 9; As shown in Figure 2, the perisporium of described non-return seat 12 is provided with many air flues 13 vertically, and described air flue 13 is connected described valve port 6 with described body 1 lower end mouth.
Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.As depicted in figs. 1 and 2, the outside thread 4 with body 1 is rotatably connected in the gas tank intake interface earlier, and the high-pressure rubber pipe that will connect the air pump air outlet again is connected with adapter 5.When air compressor compressed pneumatic pump proper functioning, air pressure overcomes and it is moved down behind spring 10 resistances to open valve port 6 thereby promote steel ball 7 when the chamber body valve port, and pressurized gas enters in the gas tank and stores through the axial air flue 13 of the perisporium of non-return seat 12.When in case when running into interim outage or mechanical failure, take over 5 internal air pressures and reduce suddenly, this moment spring 10 fast bounce-back make 7 moments of steel ball block valve port 6, realize unidirectional check function.
