Abstract
The utility model discloses a kind of lift check valve, including valve body, inlet channel is fixedly connected with the left of the valve body, water outlet is fixedly connected with the right side of the valve body, bonnet has been bolted to connection at the top of the valve body, sealing ring is provided between the valve body and bonnet, both sides at the top of the body cavity have been fixedly connected with contiguous block, the contiguous block offers chute away from the side of valve interior wall, mobile bar is set between the chute, and the both sides of the mobile bar are fixedly connected with the boss being adapted with chute.The lift check valve, by the improvement to valve element, so that valve element displacement shortens, reduce the abrasion of mobile bar, the effect of extension check-valves service life is reached, by the use to support spring so that can be closed between valve element and valve body tight, avoid and the phenomenon of refluence occur because valve element is not closed completely, reached the effect for ensureing user using safety.
Description
Technical field
The utility model is related to valve technology field, specially a kind of lift check valve.
Background technology
Check-valves refers to be flowed in itself by medium and automatic open and close valve element, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve, check-valves belong to a kind of automatic valve, and its Main Function is to prevent medium from falling
Flow, prevent pump and drive motor from inverting, and vessel media is released, the displacement of valve element when traditional check-valves is used
It is long, the abrasion between valve element and valve seat is accelerated, while the service life of check-valves is shortened, to the use band of user
Carry out certain potential safety hazard, existing check valve seal is not tight, easily occur flowing backwards phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of lift check valve, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of lift check valve, including valve body,
Inlet channel is fixedly connected with the left of the valve body, water outlet, the top of the valve body are fixedly connected with the right side of the valve body
Bonnet is bolted to connection, sealing ring, the both sides at the top of the body cavity have been provided between the valve body and bonnet
Contiguous block is fixedly connected with, the contiguous block offers chute away from the side of valve interior wall, has been set between the chute and moved
Lever, the both sides of the mobile bar are fixedly connected with the boss being adapted with chute, are fixedly connected with the top of the mobile bar
Support spring, the top of the support spring is fixedly connected with the bottom of bonnet, and the bottom of the mobile bar is fixedly connected with valve
Core.
Preferably, it has been fixedly connected with mounting disc, and mounting disc on the right side of the left side of the inlet channel and water outlet and has been opened
It is provided with mounting hole.
Preferably, the boss is connected with slide.
Preferably, the bottom of the valve element is fixedly connected with vibration damper plate.
Preferably, the bottom of the vibration damper plate is fixedly connected with sealing block.
Compared with prior art, the beneficial effects of the utility model are：The lift check valve, changes by valve element
Enter, under the using cooperatively of mobile bar so that valve element displacement shortens, reduce the abrasion of mobile bar, reached extension and stopped
The effect of valve service life is returned, the use cost of user has been saved, by the use to support spring so that valve element and valve body
Between can close it is tight, it is to avoid because valve element is not closed completely the phenomenon for occurring flowing backwards, has reached guarantee user and used peace
Full effect, the device structure is simple, should be widely promoted.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1 valve body, 2 inlet channels, 3 water outlets, 4 bolts, 5 bonnets, 6 sealing rings, 7 contiguous blocks, 8 chutes, 9 mobile bars,

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1 is referred to, the utility model provides a kind of technical scheme：A kind of lift check valve, including valve body 1, valve body 1
Left side be fixedly connected with inlet channel 2, the right side of valve body 1 is fixedly connected with water outlet 3, the left side of inlet channel 2 and water outlet 3
Right side has been fixedly connected with and mounting hole 15 has been offered in mounting disc 14, and mounting disc 14, and the top of valve body 1 is fixed by bolt 4
Bonnet 5 is connected with, sealing ring 6 is provided between valve body 1 and bonnet 5, whole valve seal effect is made more preferably using sealing ring 6,
The both sides of the inner cavity top of valve body 1 have been fixedly connected with contiguous block 7, and contiguous block 7 offers chute 8 away from the side of the inwall of valve body 1,
Mobile bar 9 is set between chute 8, and the both sides of mobile bar 9 are fixedly connected with the boss 10 being adapted with chute 8, boss 10 and cunning
Groove 8 is slidably connected, and the top of mobile bar 9 is fixedly connected with support spring 11, and the top of support spring 11 is consolidated with the bottom of bonnet 5
Fixed connection, the closing velocity of valve element 12 is accelerated using support spring 11, and the bottom of mobile bar 9 is fixedly connected with valve element 12, valve element
12 bottom is fixedly connected with vibration damper plate 13, and the bottom of vibration damper plate 13 is fixedly connected with sealing block 16.
Operation principle：When using, medium enters from inlet channel 2, when the support force of the pressure more than support spring 11 of medium
When, valve element 12 is opened, and last medium flows out from water outlet 3, and when phenomenon occurs flowing backwards in medium, the pressure of inlet channel 2 is less than
The pressure of water outlet 3, valve element 12 is closed in the presence of support spring 11, finally prevents the refluence of medium.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out various changes in the case where principle of the present utility model and spirit is not departed from, repaiies
