Abstract
The invention relates to a one-way valve, in particular to a one-way valve convenient to clean. The one-way valve comprises a valve body. An oil inlet is formed in the top of the valve body. An oil outlet is formed in the upper portion of the side wall of the valve body. A spring base is arranged below an inner cavity of the valve body. A spring facing the oil inlet is arranged on the spring base. A spherical valve element is arranged at one end, corresponding to the oil inlet, of the spring. The diameter of the valve element is larger than the opening diameter of the oil inlet. When no oil pressure is exerted to the oil inlet, the valve element and the oil inlet are in sealing fit. The one-way valve is characterized in that the bottom of the valve body is open, an external thread is arranged on the outer wall of the spring base, an internal thread is arranged on the inner side wall, corresponding to the spring base, of the valve body, the spring base enters the inner cavity of the valve body from the opening in the bottom of the valve body, and the external thread of the spring base and the internal thread of the inner side wall of the valve body are matched together. When the valve element and the spring inside the one-way valve need to be cleaned and maintained, the process is simple, and operation is convenient.
Description
Technical field
The present invention relates to a kind of one-way valve, is the one-way valve of convenient cleaning specifically.
Background technique
All know in universal machine industry, in a lot of hydraulic tubing, all one-way valve can be installed.
At present, the one-way valve used in industry comprises valve body, and filler opening is arranged at the top of valve body, and oil outlet is arranged at the top of body wall, and the below of body cavity is fixedly connected with spring seat.Described spring seat has towards the spring of filler opening, there is spherical spool that one end of the corresponding filler opening of spring, and the diameter of spool is greater than the bore of filler opening, when filler opening does not have oil pressure, in being sealed and matched between spool and filler opening.During use, valve body is installed to the relevant position in hydraulic tubing.When this one-way valve needs to carry out cleaning maintenance to the spool of its inside and spring, because spring seat is fixed on valve body, so need whole valve body to disassemble from hydraulic tubing to carry out cleaning maintenance again, process is more loaded down with trivial details, inconvenient operation.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of one-way valve, and this one-way valve is when needing to carry out cleaning maintenance to the spool of its inside and spring, and process is simpler, easy to operate.
For solving the problem, provide following technological scheme:
The one-way valve of convenient cleaning of the present invention comprises valve body, and filler opening is arranged at the top of valve body, and oil outlet is arranged at the top of body wall, and there is spring seat the below of body cavity.Described spring seat has towards the spring of filler opening, there is spherical spool that one end of the corresponding filler opening of spring, and the diameter of spool is greater than the bore of filler opening, when filler opening does not have oil pressure, in being sealed and matched between spool and filler opening.Be characterized in that the bottom of described valve body is opening-like, the outer wall of described spring seat there is outside thread, the valve body madial wall corresponding with spring seat there is internal thread, described spring seat enters into body cavity from the opening of body base, and the outside thread of spring seat is together with the screw-internal thread fit of valve body madial wall.
Wherein, the outer side wall of described spring seat there is O-ring seal.
Take above scheme, have the following advantages:
Because the body base of the one-way valve of convenient cleaning of the present invention is opening-like, the outer wall of spring seat there is outside thread, the valve body madial wall corresponding with spring seat there is internal thread, spring seat enters into body cavity from the opening of body base, and the outside thread of spring seat is together with the screw-internal thread fit of valve body madial wall.So when needing to carry out cleaning maintenance to the spool of its inside and spring, only spring seat need be turned on, it is taken out from the opening of body base, valve body can be taken out and spring carries out cleaning maintenance, thus do not need whole valve body to take out from hydraulic tubing, simplify whole servicing operations, make the convenience that the operation of maintenance washes becomes.
Accompanying drawing explanation
Fig. 1 is the structural representation of the one-way valve of convenient cleaning of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, the one-way valve of convenient cleaning of the present invention comprises valve body 1, and the top of valve body 1 is processed with filler opening 2, and the top of valve body 1 sidewall is processed with oil outlet 3, and there is spring seat 4 below of valve body 1 inner chamber.Described spring seat 4 has towards the spring 5 of filler opening 2, that one end of the corresponding filler opening of spring 52 is provided with spherical spool 6, the diameter of spool 6 is greater than the bore of filler opening 2, when filler opening 2 does not have oil pressure, in being sealed and matched between spool 6 and filler opening 2.The bottom of described valve body 1 is opening-like, the outer wall of described spring seat 4 is processed with outside thread, valve body 1 madial wall corresponding with spring seat 4 is processed with internal thread, described spring seat 4 enters into valve body 1 inner chamber from the opening bottom valve body 1, and the outside thread of spring seat 4 is together with the screw-internal thread fit of valve body 1 madial wall.The outer side wall of described spring seat 4 there is O-ring seal 7.
When the one-way valve of this convenience cleaning needs to carry out cleaning maintenance to the spool 6 of its inside and spring 5, only need turn on spring seat 4, it is taken out from the opening bottom valve body 1, valve body 1 can be taken out and spring 5 carries out cleaning maintenance, thus do not need whole valve body 1 to take out from hydraulic tubing, simplify whole servicing operations, make the convenience that the operation of maintenance washes becomes.
