Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of ready-package ball check valve, as shown in Figure 1, including valve body 1, being set to the check ball 2 of 1 inner cavity of valve body.Valve
Body 1 includes the receiving portion 12 for placing check ball 2, and 12 side of receiving portion, which is fixedly connected, to be useful for by clip connecting with water inlet pipe
Water entering section 11, the opposite side connect is fixedly connected with the outlet part 13 being useful for outlet pipe by clamp connection.
As shown in Fig. 2, outlet part 13 and the minimum diameter of receiving portion 12 are all higher than the diameter of check ball 2 so that check ball 2
Receiving portion 12 can be filled in from 13 opening of outlet part.The internal diameter of outlet part 13 along water entering section 11 towards the direction of outlet part 13 by
It is cumulative big so that check ball 2 easily can be caught in 12 inner cavity of receiving portion by outlet part 13, improve packaging efficiency.Water entering section
11 internal diameter towards 12 side of receiving portion is less than the diameter of check ball 2 so that check ball 2 can not pass through water entering section 11, so as to rise
To the effect of anti-backflow.The direction of the internal diameter of receiving portion 12 along water entering section 11 towards outlet part 13 first increases is reduced afterwards so that
The water-flowing amount of valve body 1 increases.
As shown in Figure 1 and Figure 2, outlet part 13 is symmetrically arranged with away from the side of receiving portion 12 and is connected with 13 inner cavity of outlet part
Fixing groove 131, be provided with gag lever post 3 between two fixing grooves 131.3 both ends of gag lever post are stuck in check ball 2 after fixing groove 131
Outlet part 13 can not be passed through, and flow can flow out at outlet part 13 at this time.The length of gag lever post 3 is less than two fixing grooves
Maximum distance between 131,3 both ends of gag lever post are semicircle in hemispherical and 131 cross sectional shape of fixing groove so that staff
Can 3 both ends of gag lever post be easily caught in corresponding fixing groove 131.
As shown in Figure 1 and Figure 2,3 middle section of gag lever post is fixedly connected with supporting rod 4, and gag lever post 3 is caught in fixing groove 131
Afterwards, supporting rod 4 can extend into receiving portion 12.Check ball 2 is supported during being moved by flow action and towards outlet part 13
The limiting of 12 inner wall of bar 4 and receiving portion and can not move, so as to avoid check ball 2 repeatedly with 12 inner wall of receiving portion collide after occur
Damaged situation.Gag lever post 3 and supporting rod 4 are integrally formed, and check ball 2 first are filled in 1 inner cavity of valve body when assembling check-valves, then will
3 both ends of gag lever post are caught in corresponding fixing groove 131, and assembling process is simple, efficient, time saving and energy saving.
As shown in Fig. 2, the depth of fixing groove 131 is more than the diameter of gag lever post 3 so that gag lever post 3 can be along 1 axis of valve body
It moves in heart line direction.Gag lever post 3 is influenced by impulse force and is moved towards 11 direction of water entering section during reflux, so as to generate work to check ball 2
Firmly so that check ball 2 shortens the time required to being moved to the process contacted with water entering section 11, enhances the effect of anti-backflow.
As shown in Figure 1 and Figure 2, during being moved due to the drive supporting rod 4 of gag lever post 3 along 1 direction of axis line of valve body,
Supporting rod 4 after wall friction in receiving portion 12 with easily causing 12 inner wall of receiving portion to generate cut, so that 12 inner wall of receiving portion
The area increase contacted with fluid, is easy to cause 12 inner wall of receiving portion and is aoxidized or corroded.Therefore supporting rod 4 is far from gag lever post 3
One end to be hemispherical so that supporting rod 4 and the contact area of 12 inner wall of receiving portion are reduced, and 12 inner wall of receiving portion is so as to be not easy
Generate cut.
As shown in Figure 1 and Figure 2, check ball 2 is made of polytetrafluoroethylene (PTFE) so that check ball 2 has antiacid alkali resistant, hardly
It is dissolved in that all solvents, high temperature resistant, friction coefficient polar region, service life is long, it is excellent hardly to adhere to any substance, nonhazardous etc.
Point, suitable for various fluids.Water entering section 11 is both provided with what is be caught in for sealing ring with outlet part 13 away from the side of receiving portion 12
Sealing ring is caught in the sealing that can be improved after seal groove 14 and be connected between valve body 1 and water inlet pipe and outlet pipe by seal groove 14
Property.
The course of work：
During assembling, check ball 2 is first caught in 12 inner cavity of receiving portion from 13 opening of outlet part, it is straight then to adjust supporting rod 4
To it towards receiving portion 12, then 3 both ends of gag lever post are caught in corresponding fixing groove 131.
During work, check ball 2 is moved by flow action and towards outlet part 13 until being connect with 12 inner wall of receiving portion and supporting rod 4
It touches.During reflux check ball 2 contacted with water entering section 11 and water entering section 11 is open it is closed, so as to play the effect of anti-backflow.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model by Patent Law.
