Description
Technical field
The present invention relates to a kind of pipeline valve more particularly to a kind of clip check-valves.
Background technique
In order to realize the normal work of water pump, it usually needs a check-valves is connected in the water outlet of water pump, so as in water
Pump cuts off pipeline when stopping working, to prevent the high pressure water reflux in pipeline from causing the damage to water pump.Existing check-valves
Basic structure includes the check valve body and non-return valve seat being removably docking together up and down, so that a check valve chamber is formed,
Non-return valve seat is equipped with inlet and outlet, and a spool moving up and down, the upper end of spool are arranged in check valve chamber
Equipped with pressure spring, spool lower end is equipped with seal head, is equipped with flexible sealing cup in the junction of spool and pressure spring, seals skin
The edge of bowl is crimped between check valve body and the abutting edge of non-return valve seat, so that check valve chamber is separated into uuper valve chamber under
Valve chamber, pressure spring are sealed in uuper valve chamber, on the one hand can protect pressure spring, it is avoided to get rusty and fail, while can experience lower valve chamber
Water pressure and push spool to act upwards.When pump working, the water inlet of non-return valve seat is entered by the high pressure water that water pumps out
Mouth simultaneously acts on the seal head of spool lower end, opens water inlet so that spool be pushed to move up, under high pressure water enters
In valve chamber, sealing cup at this time in the presence of hydraulic pressure band movable valve plug continue to move up, thus make on non-return valve seat into
The mouth of a river is connected to water outlet by lower valve chamber, and water supply pipe is fully opened, water system normal water supply；When water pump stops working
When, the decline of water inlet hydraulic pressure, the pressure acted on sealing cup declines therewith, and spool is under the action of pressure spring to moving down at this time
Dynamic to reset, the seal head blocking water inlet of spool lower end avoids the high pressure water shape in check-valves upper pipeline to cut off pipeline
At reflux.But above-mentioned check valve structure has following defects that firstly, spool is solid by a flexible sealing cup
It is scheduled on valve body, therefore, when spool moves up and down, the seal head of spool lower end will shake left and right and deviate original position
It sets, and seal head has slight inclination, water inlet can not be fully sealed so as to cause seal head；Secondly, in pump working
In the process, once there is the fluctuation of pressure of supply water, the pressure being subject on sealing cup reduces therewith, and correspondingly, spool change can produce
The raw fluctuation for moving up and down and causing water inlet size, and then lead to the fluctuation of water supply flow, it is unfavorable for water pump water supply system
Stable operation.
Summary of the invention
The present invention provides that a kind of simple structure, the operation is stable, production cost be low, service life in order to solve problem above
Long, convenient to install and maintain, safety and sanitation clip check-valves.
The technical scheme is that the check-valves includes front valve shell, sealing ring, spring, gasket, rear valve body,
Spool and clip, the front valve shell and rear valve body are fixed together by clip, and the spool is arranged in front valve shell
Interior, the spring is arranged on spool, and the engaging portion of the spool and front valve shell is provided with sealing ring, the sealing ring
For annular seal ring, the engaging portion between the front valve shell and rear valve body is provided with gasket.
The configuration of the present invention is simple, the operation is stable, production cost be low, long service life, convenient to install and maintain, safety and sanitation.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 is front valve shell in figure, and 2 be sealing ring, and 3 be spring, and 4 be gasket, and 5 be rear valve body, and 6 be spool, and 7 be clip.
Specific embodiment
A kind of clip check-valves, the check-valves include front valve shell 1, sealing ring 2, spring 3, gasket 4, rear valve body 5,
Spool 6 and clip 7, the front valve shell 1 and rear valve body 5 are fixed together by clip 7, and the setting of spool 6 exists
In front valve shell 1, the spring 3 is arranged on spool 6, and the engaging portion of the spool 6 and front valve shell 1 is provided with sealing ring 2,
The sealing ring 2 is annular seal ring, and the engaging portion between the front valve shell 1 and rear valve body 5 is provided with gasket 4.
Above embodiments are only to illustrate the invention and not limit technical solution described in the invention；Cause
This, is although this specification has been carried out detailed description to the invention referring to above-mentioned each embodiment, this field
It is to be appreciated by one skilled in the art that still can modify to the invention or equivalent replacement；And all do not depart from this
The technical solution and its improvement of the spirit and scope of innovation and creation, should all cover the scope of the claims in the invention
In.
