Description
Technical field
The utility model relates to water-tight equipment technical field, specially a kind of check valve seal assembly peculiar to vessel.
Background technique
Check valve is also known as check-valves or non-return valve, for preventing oil stream reverse flow in hydraulic system, or for pneumatic
Compressed air reverse flow is prevented in system.Check valve has through type and two kinds of right-angle type.Straight check valve is threadedly coupled
It is installed on the pipeline, angle check valve has threaded connection, board-like connection and three kinds of forms of flanged joint.Hydraulic control one-way valve is also referred to as
Locking-valve or pressure retaining valve, it is identical as check valve, to prevent oil liquid reverse flow.But need oil stream reversed in hydraulic circuit
Check valve is opened, keeps oil stream all flowable in both direction using control oil pressure again when flowing.Hydraulic control one-way valve uses taper
Spool, therefore good seal performance can use this valve to play pressure maintaining effect as the one-way locking of oil circuit when requiring closing oil path.
The leakage way of hydraulic control one-way valve control oil has internal drainage type and leaks two kinds of formula, can in the oil circuit that oil stream reversely exports no back pressure
Use internal drainage type；Otherwise it needs with the formula of leaking, to reduce control-oil pressure.
Existing device is under the impact of fluid, so that the mutual collision between device, causes device to have damage, for a long time
Go down to lead to the damage of device, and fluid has biggish impact force to sealing device, it is larger to the pressure of spool, it causes to make
With the shortening in service life, even valve invalidation.
Utility model content
The purpose of this utility model is to provide a kind of check valve seal assemblies peculiar to vessel, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of check valve seal assembly peculiar to vessel, including
Valve body and support plate, the intermediate position of the valve body offer fluid channel, and one end of the fluid channel is valve body outlet end,
The other end of the fluid channel is valve body import end, and the intermediate position of the valve body offers reseting cavity, opens in the valve body
Equipped with seal chamber, the seal chamber is mounted in reseting cavity close to valve body import end, the support plate, and the support plate is close
The both ends of valve body import end side surface are fixed with ball sealer, and the surface of the ball sealer is equipped with sealing ring, and the support plate is close to valve
The side of body outlet end is equipped with reset spring, and one end of the reset spring is fixed on the supporting plate.
Preferably, the reseting cavity and fluid channel penetrate through, and the reseting cavity and seal chamber penetrate through, the seal chamber design
For semicircle.
Preferably, the support plate is fixed with spool close to the side at valve body import end, and the spool is located at fluid channel
It is interior.
Preferably, the ball sealer and sealing ring are respectively positioned in seal chamber.
Preferably, the other end of the reset spring is fixed on the top of reseting cavity close to the edge of fluid channel.
Compared with prior art, the utility model has the beneficial effects that this check valve seal component architecture peculiar to vessel is simple:
1, support plate is equipped with by the top in spool, the fluid to come from valve body outlet end adverse current is stopped
Meanwhile having dispersed the impact force of fluid, the suffered pressure of spool itself is reduced, ensure that spool uses the time；
2, by being fixed with reset spring between support plate and reseting cavity, impact force suffered by support plate is slowed down, and
And the collision dynamics between device is slowed down, long-term use is enabled a device to, and be equipped in the bottom of support plate close
Blocking and ball sealer are equipped with sealing ring and will be pressed on inside sealing ring and seal chamber in the fluid impulse force by adverse current
Together, it ensure that the leakproofness of device.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of check valve seal assembly peculiar to vessel, including valve
Body 1 and support plate 7, the intermediate position of the valve body 1 offer fluid channel 2, and one end of the fluid channel 2 is valve outlet
The other end at end 3, the fluid channel 2 is valve body import end 3, and the intermediate position of the valve body 1 offers reseting cavity 5, described
Seal chamber 10 is offered in valve body 1, the seal chamber 10 is mounted on reseting cavity 5 close to valve body import end 4, the support plate 7
Interior, the support plate 7 is fixed with ball sealer 8 close to the both ends of 4 side of valve body import end, and the surface of the ball sealer 8 is equipped with close
Seal 9, the support plate 7 are equipped with reset spring 11 close to the side of valve body outlet end 3, and one end of the reset spring 11 is solid
It is scheduled in support plate 7.
The reseting cavity 5 is penetrated through with fluid channel 2, and the reseting cavity 5 is penetrated through with seal chamber 10, and the seal chamber 10 designs
For semicircle, the support plate 7 is fixed with spool 6 close to the side at valve body import end 4, and the spool 6 is located at fluid channel 2
