Abstract
The utility model provides a one-way valve which comprises a valve body, a valve core and two springs. The valve core is installed in the valve body, the valve core is supported by the springs, the springs are pressed by water pressure, the springs can drive the valve core to carry out opening and closing motion, the springs are sleeved on a support rod, the support rod is used for fixing the two springs to prevent the springs from bending and deforming in the valve body in a spring compressor process, and the top end of the support rod is always in a small hole at the top of the valve body instead of extending out of the small hole to affect installation of other members. The one-way valve is simple in structure. The double-spring design mainly aims at solve the problems that the one-way valve is untight in locking in a locking process caused by uneven radial force of the springs, and the valve core is blocked at the outlet position to be prone to deform for a long time.
Description
Technical field
The utility model relates to a kind of one-way valve.
Background technique
Existing individual event valve, its sealing effect is not good enough.At the state of not water flowing, water leakage fault often occurs, and, existing one-way valve, spool is generally metal material, under the bad state of water quality, is corroded than being easier to, and affects the working life of one-way valve and has the not tight situation of water of closing.Now be badly in need of improving existing one-way valve, to avoid the generation of the above defective.
The model utility content
For realizing the above, the technological scheme that the utility model provides is as follows: a kind of one-way valve, and described individual event valve comprises valve body, spool and spring, spool is installed in the valve body, the spring supporting spool, hydraulic pressure presses spring, and the spring band movable valve plug is opened and the action of closing; Described spring has two.
Further, described spring housing is on strut, and strut is used for fixedly dual spring, in order to avoid in the Compress Spring process, spring occurs bending and deformation in valve body.
Further, the masthead end of described strut all is in the aperture at valve body top in telescopic process, in order to avoid stretch out outside the aperture, affects the installation of other member.
This one-way valve that the utility model relates to, simple in structure, the design of dual spring mainly is that the reply one-way valve is in the locking process, locking is not tight, one of them reason is exactly that the radial force of spring is inhomogeneous, cause spool get lodged in the outlet port of a specified duration distortion occured, the design is dual spring, can solve the above defective.
Description of drawings
Fig. 1 is a kind of one-way valve structures schematic diagram of the utility model;
The 1-valve body; The 2-spool; The 3-spring; The 5-strut.
Embodiment
As shown in Figure 1, this one-way valve comprises valve body 1, spool 2 and spring 3, and spool 2 is installed in the valve body 1, and spring 3 supports spool 2, and hydraulic pressure presses spring 3, and spring 3 is opened and the action of closing with movable valve plug 2; Described spring 3 has two.
The masthead end of strut 5 all is in the aperture at valve body 1 top in telescopic process, in order to avoid stretch out outside the aperture, affects the installation of other member.
This individual event valve that the utility model relates to, simple in structure, good sealing effect can prolong working life of one-way valve.
Embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
Claims (2)
1. an one-way valve is characterized in that, described individual event valve comprises valve body, spool and spring, and spool is installed in the valve body, the spring supporting spool, and hydraulic pressure presses spring, and the spring band movable valve plug is opened and the action of closing; Described spring has two, and described spring housing is on strut, and strut is used for fixedly dual spring, in the Compress Spring process, prevents that spring from occuring bending and deformation in valve body.
2. a kind of one-way valve according to claim 1 is characterized in that, the masthead end of described strut all is in the aperture at valve body top in telescopic process, in order to avoid stretch out outside the aperture, affects the installation of other member.
