Specific embodiment
Embodiment 1: as shown in Figure 1, the present embodiment is a kind of safety check valve component, there is valve body, pilot hole plug, pressure
Power table, relief valve assembly, air inlet tube and outgoing gas connection tube.
As shown in Fig. 2, having through-hole in this example in valve body, one end of through-hole is air inlet, and the other end of through-hole is assembly
Hole, the through-hole is interior to be equipped with unidirectional valve group, and through-hole is divided into close to the air inlet section of air inlet and going out close to pilot hole by unidirectional valve group
Gas section.The venthole being connected to the air outlet section of through-hole, safety valve mounting hole and pressure gauge mounting hole are formed on valve body.
Unidirectional valve group includes the bellmouth being set in turn in through-hole from pilot hole, valve ball and blocks card in this example,
Middle bellmouth and through-hole are coaxially arranged, and the bigger diameter end of the bellmouth blocks during card center is provided with towards the assembly nose end of through-hole
Heart hole, this, which is blocked, is uniformly provided with multiple ventholes around the centre bore of card.It blocks card to be positioned in through-hole through circlip, block
Spring cooperates the card slot in through hole wall to realize positioning.When the pressure of air inlet section is higher than the pressure of air outlet section, valve ball leaves taper
Hole wall is attached on the centre bore for blocking card, and air-flow flows to air outlet section from the venthole for blocking card periphery；When the gas of air outlet section
When pressure is higher than air inlet section side, valve ball is just adjacent to bellmouth, and gas is flowed to truncation, air-flow is prevented to pass through.
Air inlet and pilot hole are coaxial in the present embodiment, machine convenient for body cavity, in the cone for machining upper conical hole
Face smoothness requirements are relatively high, and the diameter of pilot hole wants sufficiently large, can protrude into the cutter head of turning, can be packed into valve ball, block card
And circlip.
The air inlet of valve body connects air inlet tube, and pilot hole is linked and packed hole plug, and venthole connects outgoing gas connection tube, safety valve
Mounting hole connection safety valve component, pressure gauge mounting hole is interior to install pressure gauge.
As shown in figure 3, relief valve assembly has emergency valve seat and safety valve cap in this example, safety valve is formed in emergency valve seat
Hole, the emergency valve seat one end connect valve body, other end connection safety valve cap, and interior be equipped with of safe valve opening is connected to the air outlet section of through-hole
Relief tube, the pressure release pipe outside diameter be less than safe valve opening aperture, emergency valve seat with the company of opening up in the relief tube corresponding segment in it
Lead to region between safe valve opening and relief tube has relief hole, which is built-in with air valve, and air valve one end is connected through spring
Safety valve cap, other end apical grafting pressure release end surfaces block relief tube.When the pressure in relief tube is more than safety value, air valve quilt
It pushes open, spring-compressed, relief tube is connected to through region between safe valve opening and relief tube with the relief hole on emergency valve seat, thus real
It is now automatic to lose heart, to protect the safety of valve body safety and pipe-line system.
It is provided with pressure regulating screw in safety valve cap end in the present embodiment, pressure regulating screw internal screw thread connects pressure regulation bar, the pressure regulation
Bar connecting spring.Pressure regulation bar by realizing that distance is adjusted with the connection screw thread of safety valve cap, and then adjust pressure regulation bar and air valve it
Between distance, keep spring stress adjustable, be adjusted to safeguard protection vent pressure that pressure gauge is shown just can with the reading of pressure release,
Ensure within safeguard protection vent pressure, air valve seals pressure release nozzle, does not allow compressed air leakage in pipe.
Embodiment 2: as shown in figure 4, the present embodiment is substantially the same manner as Example 1, it the difference is that only that the present embodiment exists
Safety valve mounting hole is set on pilot hole plug.
Embodiment 3: as shown in figure 5, the present embodiment is substantially the same manner as Example 1, it the difference is that only that the present embodiment exists
Venthole is set on pilot hole plug.
The utility model is not limited to above-described embodiment, it is noted that those skilled in the art can be practical new at this
On the basis of type, not needing creative labor can be replaced or modify to some or certain features, these are replaced or repair
Change within the protection scope of the present utility model.
