Abstract
The utility model discloses a novel lift check valve, including the valve body, be equipped with the disk seat in this valve body, this disk seat upper cover is equipped with the valve clack that can open, close, the lateral surface of valve body is equipped with a convex part, this a convex part and valve body body coupling, be equipped with the activity space in the convex part, the inside wall of valve body is equipped with movable groove, and this activity groove sets up with corresponding and communicates with the activity space, the valve clack is equipped with the connecting rod, and the one end and the valve clack fixed connection of this connecting rod, its other end pass movable groove postposition in the activity space, and the other end of this connecting rod is articulated through round pin axle and convex part. The utility model discloses simple structure, the practicality is strong. The valve clack is realized its division with the articulated of convex part, is closed through the connecting rod, the connection of valve clack can be guaranteed to the convex part, and its structure is simple more simultaneously, manufacturing cost is lower, and just along with the lapse of live time, it can not take place the drainage, reduces safeguarding number of times and time of people, has improved the life of this check valve greatly.
Description
Technical field
The utility model relates to valve field, refers to a kind of novel Lift check valve specifically.
Background technique
Lift check valve, its effect only allows medium to flow to a direction, and stop the reverse flow of medium.Usual this valve is automatic operation, and under the fluid pressure action of a direction flowing, flap is opened; During fluid opposite direction, by hydrodynamic pressure, flap is closed on valve seat, thus cut off flowing.Existing Lift check valve, comprise valve body, valve seat is provided with in this valve body, this valve seat is covered with can the flap of open and close, the periphery of described valve body is provided with the boss be communicated with it, the inside of this boss is hollow structure, and the end face of this boss is provided with end cap, and the joint of this end cap and boss is provided with sealing gasket.Along with the passing of service time, sealing gasket can slowly aging and corrosion, thus lose sealing effect, now namely boss can produce water leakage phenomenon.
Model utility content
The utility model provides a kind of novel Lift check valve, and its main purpose is the problems referred to above overcoming prior art existence.
The utility model adopts following technological scheme to be achieved:
A kind of novel Lift check valve, comprise valve body, valve seat is provided with in this valve body, this valve seat is covered with can the flap of open and close, the outer side surface of described valve body is provided with a protuberance, this protuberance is connected with valve body, activity space is provided with in described protuberance, the madial wall of described valve body is provided with loose slot, this loose slot and activity space arrange accordingly and are communicated with, and described flap is provided with connecting rod, and one end of this connecting rod is fixedly connected with flap, its the other end through being positioned at activity space after loose slot, and the other end of this connecting rod by bearing pin and protuberance hinged.
Further, described flap is coated with stuffing box gland, and described connecting rod is connected with stuffing box gland.
Further, described stuffing box gland is rubber sealing boot.
From above-mentioned to description of the present utility model, compared to the prior art, the utility model tool has the following advantages:
1, the utility model structure is simple, practical.Described flap realizes its open and close by the hinged of connecting rod and protuberance, described protuberance can guarantee the connection of flap, its structure is more simple simultaneously, cost of production is lower, and along with the passing of service time, can not water leakage phenomenon be there is in it, reduce maintenance times and the time of people, substantially increase the working life of this safety check.
2, described stuffing box gland is in the inner coated by flap, and operationally, flap can not contact with aqueous phase this safety check, and such flap also just not easily gets rusty, corrodes, and maintains the clean of water, reduces the pollution of water, also extends the working life of flap simultaneously.
Accompanying drawing explanation
Fig. 1 is cross-sectional schematic of the present utility model.
Fig. 2 is the cross-sectional schematic of the utility model flap.
Embodiment
With reference to Fig. 1.A novel Lift check valve, comprises valve body 1, is provided with valve seat 2 in this valve body 1, and this valve seat 2 is covered with can the flap 3 of open and close.The outer side surface of described valve body 1 is provided with a protuberance 4, and this protuberance 4 is connected with valve body 1 one, is provided with activity space 41 in described protuberance 4.The madial wall of described valve body 1 is provided with loose slot 11, and this loose slot 11 and activity space 41 arrange accordingly and be communicated with.Described flap 3 is provided with connecting rod 31, and one end of this connecting rod 31 is fixedly connected with flap 3, its other end through being positioned at activity space 41 after loose slot 11, and the other end of this connecting rod 31 by bearing pin and protuberance 4 hinged.
With reference to Fig. 1.Described flap 3 realizes its open and close by connecting rod 31 and the hinged of protuberance 4, described protuberance 4 can guarantee the connection of flap 3, its structure is more simple simultaneously, cost of production is lower, and along with the passing of service time, can not water leakage phenomenon be there is in it, reduce maintenance times and the time of people, substantially increase the working life of this safety check.
See figures.1.and.2.Described flap 3 is coated with stuffing box gland 5, and sealing cover 5 is rubber sealing boot, and described connecting rod 31 is connected with stuffing box gland 5.Described stuffing box gland 5 is by the inner coated for flap 3, and operationally, flap 3 can not contact with aqueous phase this safety check, and such flap 3 also just not easily gets rusty, corrodes, and maintains the clean of water, reduces the pollution of water, also extends the working life of flap 3 simultaneously.
Above are only embodiment of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
