Abstract
A one-way valve with a replaceable damper comprises a valve sleeve, a valve core and a damper; the valve sleeve is matched with the valve core, a damper is arranged in the valve sleeve, and the damper is assembled with the valve core in a detachable mode. The damper of the one-way valve and the valve core are in detachable connection, so that only the damper on the valve core is replaced when the damper needs to be replaced, the complex work caused by replacing damper is reduced, and the replacing efficiency is improved. The one-way valve with the replaceable damper achieves the replacement of different dampers in different occasions and convenient and flexible utilization.
Description
Technical field
The utility model belongs to the one-way valve technical field, particularly relates to a kind of one-way valve with replaceable damper.
Background technique
At present, the one-way valve of domestic tubular type band damper is when damper is improper when need changing, because damping hole processes at inner elements of check valve, so need to change inner elements of check valve.
In actual applications, change inner elements of check valve 3 deficiencies arranged:
1. need to carry the large damping check valve spool of all size, carry inconvenience.
2. require the interchangeability between inner elements of check valve and the one-way valve sleeve to get well, increased the requirement to the process equipment precision.
3. if the scene does not have suitable damper, when needing to use drill bit to enlarge the damping diameter dimension, because spool process Quenching Treatment, difficulty of processing is larger.
There is the inconvenience of changing damper in existing one-way valve with damper, therefore, is necessary to design a kind of one-way valve of being convenient to change damper.
Summary of the invention
The technical problem that (one) will solve
The technical problems to be solved in the utility model is: the existing problem that has the complexity of changing damper with the one-way valve of damper, so that carry inconvenience.
(2) technological scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of one-way valve with replaceable damper.
Wherein, described one-way valve comprises valve pocket, spool and damper, and described valve pocket matches with spool, and the inside of described valve pocket is provided with damper, and described damper is removably mounted on spool.
Preferably, be threaded between described damper and the spool.
Preferably, described damper is provided with screw, and described spool is provided with screw rod, and described spool is connected with screw on the described damper by the screw rod on it.
Preferably, described damper is hydraulic damper.
(3) beneficial effect
Technique scheme has following advantage: be removably connection between the damper of the utility model one-way valve and the spool, when needs are changed damper, only need the replacing of the damper on the spool is got final product, greatly reduce and change the complex work that damper brings, improved replacing efficient.One-way valve of the present utility model can realize changing in different occasions the damper of different size, accomplishes easy to use, flexible.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model structural representation;
Fig. 2 is the fundamental diagram of Fig. 1.
Wherein, 1: valve pocket; 2: spool; 3: damper.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, be a kind of embodiment's of the present utility model structural representation, this one-way valve comprises valve pocket 1, spool 2 and damper 3, and described valve pocket 1 matches with spool 2, the inside of described valve pocket 2 is provided with damper 3, and described damper 3 is removably mounted on spool 2.For removably connecting, when needs are changed damper, only need the replacing of the damper on the spool is got final product between the damper of the utility model one-way valve and the spool, greatly reduce and change the complex work that damper brings, improved replacing efficient.
Valve pocket 1 of the present utility model can be various suitable structures, and valve pocket 1 cooperates installation with spool 2.This damper 3 can for various suitable structures, be preferably hydraulic damper.Damper 3 can be taked removably to be connected between various suitable modes and the spool 2.Preferably, be threaded between described damper and the spool.Damper 3 among this embodiment is provided with screw, and described spool 2 is provided with screw rod, and described spool 2 is connected with screw on the described damper 3 by the screw rod on it, thereby has realized removably connecting between the two.When needs are changed damper, only need damper is got final product from the spool dismounting, improved the efficient of changing, reduced cost of labor.
As shown in Figure 2, be the fundamental diagram of Fig. 1, fluid enters one-way valve from A or B, reduces vibrations by the damper in the one-way valve.During A to B, the oil-feed of A mouth promotes spool and moves to left, and fluid mills flat place to B through spool; During B to A, the oil-feed of B mouth promotes spool and moves to right, fluid through the valve core inside damping hole to A.When needs are changed damper, can split out damping hole through the pad hole with inner hexagon spanner, change the required diameter damper and get final product, realized the purpose of convenient disassembly.
As can be seen from the above embodiments, for removably connecting, when needs are changed damper, only need the replacing of the damper on the spool is got final product between the damper of the utility model embodiment's one-way valve and the spool, greatly reduce and change the complex work that damper brings, improved replacing efficient.One-way valve of the present utility model can realize changing in different occasions the damper of different size, accomplishes easy to use, flexible.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
Claims (4)
1. the one-way valve with replaceable damper is characterized in that, described one-way valve comprises valve pocket, spool and damper, and described valve pocket matches with spool, and the inside of described valve pocket is provided with damper, and described damper is removably mounted on spool.
