Description

Silencing check valve

Technical Field

The utility model relates to a valve field, in particular to noise elimination check valve.

Background

The silencing check valve is a valve which automatically opens and closes a valve clack by medium flowing, and is used for preventing the medium from flowing backwards, and is also called a check valve, a one-way valve, a silencing check valve and a back pressure valve. The check valve is an automatic valve and mainly used for preventing medium from flowing backwards, preventing the pump and a driving motor from reversing and discharging container medium. Check valves may also be used to provide make-up lines to auxiliary systems where the pressure may rise above the system pressure. The check valve can be mainly divided into a swing check valve and a lift check valve. The poppet check valve is similar in construction to a shut-off valve in that media flows in from the inlet end (lower side) and out from the outlet end (upper side). The valve is opened when the inlet pressure is greater than the sum of the weight of the flap and its flow resistance. Otherwise, the valve is closed when the medium flows backwards. The inside deposit that can remain of valve body after check valve installation uses a period to the pipeline, and the deposit can be attached to the valve body inner wall, and the deposit can constantly pile up, influences the valve and goes out water. Meanwhile, partial sediments attached to the inner wall of the valve body can erode the inner wall of the valve body, and the service life of the valve body is shortened.

SUMMERY OF THE UTILITY MODEL

Therefore, in view of the above problems, the present invention provides a noise elimination check valve with simple structure and cleaning function.

In order to achieve the above object, the technical scheme of the utility model provides a noise elimination check valve, including the check valve body, set up in this internal fluid passage of check valve, along the radial inhalant canal and the exhalant canal of seting up of check valve body, locate first disk seat and the second disk seat of check valve body inhalant canal and exhalant canal, slidable wear to locate valve rod, a plurality of first disk seat and second disk seat and be used for clearing up the brush of fluid passage inner wall, be equipped with on the valve rod and be used for inhalant canal and the inclosed valve plate of exhalant canal, the confession has been seted up on the valve plate the mouth of dodging of brush installation, the brush is located through first block device on the valve plate, the second valve seat pass through the second block device removable install in on the check valve body.

The further improvement is that: the first clamping device comprises a first magnet, the first magnet is fixedly arranged on a brush handle of the brush, a clamping groove for the first magnet to be clamped is formed in the valve plate, and a second magnet capable of attracting the first magnet is fixedly arranged at the lower end of the clamping groove of the valve plate.

The further improvement is that: the second clamping device comprises a fixing sleeve, the second valve seat is fixedly arranged on the fixing sleeve, the fixing sleeve is in threaded connection with the check valve body, and a first sealing ring for preventing medium leakage is arranged between the second valve seat and the check valve body.

The further improvement is that: the valve plate is sleeved with a second sealing ring, and the second sealing ring is located on the brush handle of the brush and is abutted against the brush handle of the brush.

The utility model has the advantages and the beneficial effects that:

1. when fluid medium flows into the fluid channel from the water inlet channel, the valve plate slides upwards to drive the hairbrush 11 to slide upwards, so that sediments attached to the inner wall of the fluid channel are cleaned, the sediments on the inner wall of the fluid channel flow out of the water outlet channel along with the fluid medium under the action of the hairbrush, and the sediments are prevented from being adsorbed and accumulated on the inner wall of the fluid channel to influence water outlet of the valve. Meanwhile, the overlooking of the inner wall of the fluid channel caused by the sediment can be avoided, and the service life of the check valve is prolonged.

2. The arrangement of the first clamping device and the second clamping device enables the brush to be quickly replaced, the check valve can be cleaned continuously, and the service life of the check valve is further prolonged.

3. The second sealing washer can improve the leakproofness of valve plate and prevent brush cleaning process in roll-off block groove, improves check valve's practicality, reduces the maintenance.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-3, a noise elimination check valve comprises a check valve body 1, a fluid passage 2 disposed in the check valve body 1, a water inlet passage 3 and a water outlet passage 4 radially disposed along the check valve body 1, a first valve seat 5 and a second valve seat 6 disposed in the water inlet passage 3 and the water outlet passage 4 of the check valve body 1, and a valve rod 10 slidably disposed through the first valve seat 5 and the second valve seat 6, wherein the valve rod 10 is provided with a valve plate 9 for sealing the water inlet passage 3 and the water outlet passage 4, and further comprises a plurality of brushes 11 for cleaning the inner wall of the fluid passage 2, the valve plate 9 is provided with an avoiding opening for the brushes 11 to be mounted, the brushes 11 are disposed on the valve plate 9 through a first clamping device, the first clamping device comprises a first magnet 12, the first magnet 12 is fixedly disposed on a brush handle of the brushes 11, the valve plate 9 is provided with a groove for the first magnet 12 to be clamped, the valve plate 9 is located the fixed second magnet 13 that can attract mutually with first magnet 12 that is equipped with in the lower tip of block groove, second valve seat 6 through the removable dress of second clamping device in on the check valve body 1, the second clamping device is including fixed cover 7, second valve seat 6 is fixed to be located on fixed cover 7, fixed

cover

7 and 1 threaded connection of check valve body, be provided with the first sealing washer 8 that is used for preventing the medium leakage between second valve seat 6 and the check valve body 1. When fluid medium flows into the fluid channel 2 from the water inlet channel 3, the valve plate 9 slides upwards to drive the brush 11 to slide upwards, so that deposits attached to the inner wall of the fluid channel 2 are cleaned, the deposits on the inner wall of the fluid channel 2 flow out from the water outlet channel 4 along with the fluid medium under the action of the brush 11, and the deposits are prevented from being adsorbed and accumulated on the inner wall of the fluid channel 2 to influence the water outlet of the valve. Meanwhile, the phenomenon that the inner wall of the fluid channel 2 is overlooked by sediment can be avoided, and the service life of the check valve is prolonged. And the setting of first clamping device and second clamping device for brush 11 can be changed, and its with the change principle does: through rotating second valve base 6, take out fixed cover 7 and go out water passageway 4, then remove the block of first magnet 12 on the brush 11 and the second magnet 13 on the valve plate 9, then take out brush 11, then pack into valve plate 9 with new brush 11, make first magnet 12 and the actuation of second magnet 13, then threaded connection fixed cover 7, can accomplish the change, and is simple and convenient again.
