Abstract
The invention discloses a self-settling ball check valve in the valve technical field. The self-settling ball check valve comprises a valve body, wherein a water outlet and a water inlet are symmetrically formed in the top and the bottom of the valve body, a water return chamber is arranged in an inner cavity of the valve body and located between the water inlet and the water outlet, a guide pillar is vertically arranged in an inner cavity of the water return chamber, and a ball base is connected to the outer wall of the guide pillar in a sliding mode. According to the self-settling ball check valve, when the flowing rate of a medium in the valve body is reduced, self-gravity of the ball base is utilized for preventing the medium in the valve body from flowing back; a balancing weight is additionally arranged in the ball base, therefore, the settling speed of the ball check valve can be raised, the sealing effect of the ball check valve is enhanced, and the structure is simple; an annular sealing washer is arranged at the circumferential edge of the ball base, and therefore the sealing performance of the ball check valve can be further improved.
Description
Technical field
The present invention relates to valve technology field, be specially a kind of from decanter type ball check valve.
Background technology
Check-valves be used for pipe-line system, its Main Function be prevent medium flow backwards, prevent pump and drive motor machine reversion,
And the releasing of container inner medium.Check-valves can be additionally used in the auxiliary system that may be raised above main system pressure to pressure therein
System provides on the pipeline of supply.Horizontally or vertically install, can be used for cold water, hot water, industry and sanitary sewage pipe network, suitableeer
Close proof submersible sand discharging pump, medium temperature 0-80 DEG C.It is mountable at pump outlet, to prevent refluence and water hammer from pump being damaged.Example
As in China Patent No. 201120209348.3 propose a kind of ball check valve, wherein preferable to valve seal, but for
The nonreturning of valve inner medium is the highest, and when velocity of medium reduces, the medium within check-valves can not be carried out very by its valve seat
Good sealing, to this end, we have proposed a kind of from decanter type ball check valve.
Summary of the invention
It is an object of the invention to provide a kind of from decanter type ball check valve, to solve proposition in above-mentioned background technology
Valve body is not closed completely close problem.
For achieving the above object, the present invention provides following technical scheme: a kind of from decanter type ball check valve, including valve
Body, described body top and bottom symmetrical have outlet and water inlet, and described body cavity is provided with backwater room, and backwater room position
Between water inlet and outlet, described backwater room inner chamber is vertically provided with lead, and described lead outer wall slidably connects ball
Seat.
Preferably, described lead outer wall has chute, and the top of described chute is provided with projection, and the bottom of described ball seat sets
The slide block suitable with chute, described ball seat is had to be slidably connected with lead by slide block and chute.
Preferably, described ball seat is hollow structure inside, and the inner chamber of described ball seat is provided with balancing weight, the circumference of described ball seat
Surface is provided with ring packing packing ring.
Preferably, the bottom of described backwater room is the circular arc suitable with ball seat, the circular arc bottom described backwater room
Opening is less than the diameter of ball seat.
Compared with prior art, the invention has the beneficial effects as follows: should be from decanter type ball check valve, as Jie of valve inner
When mass flow prompt drop is low, utilizes the medium back flow preventing valve inner from gravity of ball seat, and add balancing weight in the inside of ball seat,
Its sedimentation velocity can be accelerated, strengthen the sealing effectiveness of ball check valve, simple in construction, be provided with annular at ball seat circumferential edges close
Seal washer can further improve its sealing.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1-4, the present invention provides a kind of technical scheme: a kind of from decanter type ball check valve, including valve body 1,
Described valve body 1 top and bottom symmetrical have outlet 3 and water inlet 2, and described valve body 1 inner chamber is provided with backwater room 4, and backwater room
4 between water inlet 2 and outlet 3, and described backwater room 4 inner chamber is vertically provided with lead 5, and described lead 5 outer wall slides
Connect and have ball seat 6.
Wherein, described lead 5 outer wall has chute 51, and the top of described chute 51 is provided with projection 52, described ball seat 6
Bottom is provided with the slide block 61 suitable with chute 51, and described ball seat 6 is slidably connected with lead 5 by slide block 61 and chute 51,
There is provided the working foundation of ball seat 6, it is possible to sliding smoothly with lead 5, described ball seat 6 is hollow structure inside, described
The inner chamber of ball seat 6 is provided with balancing weight 62, and the circumferential surface of described ball seat 6 is provided with ring packing packing ring 63, and balancing weight 62 can carry
High ball seat 6 from sedimentation velocity, set up ring packing packing ring 63 simultaneously and can strengthen its sealing effectiveness, the end of described backwater room 4
Portion is the circular arc suitable with ball seat 6, and the circular arc opening bottom described backwater room 4 is less than the diameter of ball seat 6, and ball seat 6 is not
The bottom of backwater room 4 can be skidded off, it is ensured that the work quality of check-valves.
