Elastic force drive flap move in a straight line, to complete the closure of valve.
As the further preferred technical solution of the utility model, first screw and the second screw are clamp screw
Nail.
As the further preferred technical solution of the utility model, the third screw is soket head cap screw.
As the further preferred technical solution of the utility model, first screw, the second screw and holding screw
Material is stainless steel.
As the further preferred technical solution of the utility model, the linear slide bearing of stating is distributed in for straight-line groove
The structure of bearing bore diameter.
The silent check valve of the utility model can achieve it is following the utility model has the advantages that
The silent check valve of the utility model, by including valve body, baffle, guide sleeve, valve rod, spring, valve rod base, valve
Valve, linear slide bearing, in which: the outlet end that the baffle is fixed on valve body by being threadedly engaged the first screw, it is described to lead
It is fixed on baffle to set by being threadedly engaged the second screw, the linear slide bearing is mounted in valve body and is located at guiding
The end of set, the valve rod is packed into guide sleeve and linear slide bearing, and is connected with valve rod base, and the valve rod base passes through third
Screw is fixed on the flap at valve body import end, and the spring is placed in the valve rod between valve rod base and linear slide bearing
On, to drive flap to move in a straight line by the elastic force of spring, to complete the closure of valve so that the utility model by
Guide sleeve and increased first screw in baffle junction, guide sleeve and baffle is fixed in one plane, to will lead
It is fixed to set position, avoids guide sleeve caused by stem movement and fall off, effectively extend the service life of valve.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram for the example that the utility model silent check valve provides；
Fig. 2 is the left view of silent check valve shown in Fig. 1；
Fig. 3 is the partial enlarged view in Fig. 2.
In figure: 1, valve body, the 2, first screw, 3 baffles, 4, guide sleeve, the 5, second screw, 6, valve rod, 7, spring, 8, valve
Pole socket, 9, flap, 10, third screw, 11, linear slide bearing.
The utility model aim is realized, the embodiments will be further described with reference to the accompanying drawings for functional characteristics and advantage.
Specific embodiment
Below in conjunction with attached drawing and specific embodiment, the utility model is described further.In preferred embodiment
Cited such as "upper", "lower", "left", "right", " centre " and " one " term, only being illustrated convenient for narration, rather than to
The enforceable range of the utility model is limited, relativeness is altered or modified, under the content of no substantial changes in technology, when also
It is considered as the enforceable scope of the utility model.
As shown in Figure 1, silent check valve includes valve body 1, baffle 3, guide sleeve 4, valve rod 6, spring 7, valve rod base 8, valve
Valve 9, linear slide bearing 11, in which:
The outlet end that the baffle 3 is fixed on valve body 1 by being threadedly engaged the first screw 2, the guide sleeve 4 pass through spiral shell
Line cooperates the second screw 5 to be fixed on baffle 3, and the linear slide bearing 11 is mounted in valve body 1 and is located at guide sleeve 4
End, the valve rod 6 is packed into guide sleeve 4 and linear slide bearing 11, and is connected with valve rod base 8, and the valve rod base 8 passes through the
Three screws 10 are fixed on the flap 9 of 1 input end of valve body, the spring 7 be placed in valve rod base 8 and linear slide bearing 11 it
Between valve rod 6 on, to drive flap 9 to move in a straight line by the elastic force of spring 7, to complete the closure of valve.
In specific implementation, first screw 2 and the second screw 5 are holding screw, and the third screw 10 is interior six
Angle screw, and the material of first screw 2, the second screw 5 and holding screw is stainless steel, using stainless steel material, tool
There is the advantages of tensile strength is big, be unlikely to deform, long service life, and holding screw used is relatively common, is easy to buy on the market,
Customer repair is facilitated to replace.
As shown in Figures 2 and 3, the linear slide bearing 11 of stating is the structure that straight-line groove is distributed in bearing bore diameter, when
When having impurity to flow into valve rod 6 and linear slide bearing 11 in flow media, impurity can flow into the ditch of linear slide bearing 11
In slot, effectively prevents impurity to flow into the situation for causing valve rod 6 stuck, extend the service life of valve.
The working principle of the utility model silent check valve is as follows:
When not having medium to flow through valve body 1, by the elastic force of spring 7, flap 9 is tightly pressed against on the sealing surface of valve body 1, from
And realize the closed state of valve；
When there is medium to flow through valve body 1, if input end has medium inflow, import end pressure is greater than outlet pressures and bullet
7 pressure summation of spring, then flap 9 is automatically turned on ovable valve stem 6；If the summation of 7 pressure of outlet pressures and spring is greater than import
When end pressure, then flap 9 is closed automatically.
Although those skilled in the art should manage the foregoing describe specific embodiment of the present utility model
Solution, these are merely examples, various changes or modifications can be made to present embodiment, without departing from the original of the utility model
Reason and essence, the protection scope of the utility model are only limited by the claims that follow.
