As depicted in figs. 1 and 2, the present invention provides a kind of pressure gauge explosion-proof leakage-proof quick breaker, including quick breaker ontology 1,
The quick breaker ontology includes: outlet end, input end, and tapered hollow pipe 3 and bypass pipe 8 positioned at the inner cavity of quick breaker.
Tapered hollow pipe 3, with inlet end and an outlet end vertically through the tapered hollow pipe 3 is along bigbore water inlet
Flow adjusting screw rod 5 and nonreturn valve core 4 are configured in order to small-bore water outlet direction.Flow adjusting screw rod 5 and input end
Inner sidewall be fixedly connected；Nonreturn valve core 4 is suitable in tapered hollow pipe 3 axially movable to water outlet.Flow adjusting screw rod 5
Both ends be respectively provided with inner cavity that a cross open and the flow adjusting screw rod 5 have there is hollow runner hole, the runner
The cross open in hole and the both ends for being respectively arranged at flow adjusting screw rod 5 penetrates through.
The water outlet of tapered hollow pipe 3 is configured with a sealing ring (not shown).It can be real by the sealing ring of design
Reveal combining closely between the mouth of a river and nonreturn valve core 4, further prevents leakage or gas leakage.
The nonreturn valve core 4 of the present embodiment is solid sphere.The diameter of nonreturn valve core 4 is greater than the bore of water outlet, is suitable for
Block water outlet.
Optionally, nonreturn valve core 4 is Ceramic Balls or steel ball.Ceramic Balls and steel ball are provided with mature technique, have performance
Stable advantage.
The inner sidewall of outlet end is equipped with internal screw thread 2, suitable for being connected with the pressure gauge.The inner sidewall of input end is provided with
Internal screw thread 6, and the lateral wall of the input end is provided with external screw thread 7；And the external screw thread 7 is used to connect with the pressure switch
It connects, the other end of the pressure switch is connected with pressure source C.The internal screw thread 6 of the input end is used to adjust with the flow
Screw rod 5 connects.
Bypass pipe 8, the water inlet of the bypass pipe 8 and the water inlet perforation of tapered hollow pipe 3 and going out for the bypass pipe 8
The water outlet of the mouth of a river and tapered hollow pipe 3 penetrates through；A valve module of voltage regulation 15 is provided at the water inlet of the bypass pipe 8.The pressure regulation
Valve module 15 is configured at the connectivity part of bypass pipe 8 Yu tapered hollow pipe 3, i.e., under normality, valve module of voltage regulation 15 is suitable for blocking bypass
The connectivity part of pipe 8 and tapered hollow pipe 3, so that the liquid or gas in tapered hollow pipe 3 cannot be introduced into bypass pipe 8.
Valve module of voltage regulation 15 includes: valve body 10, regulating valve stem 9, sealing ring 12, gland 11 and adjusting handle 13.Wherein
The both ends of valve body 10 are each equipped with external screw thread, are tightly connected between the external screw thread of one end and the quick breaker ontology 1, the other end
External screw thread connect with gland 11；10 internal screw thread of valve body is connect with the external screw thread of regulating valve stem 9；Regulating valve stem 9 is equipped with twice
Sealing ring 12 is suitable for forming sealing structure with valve body 10；And quick breaker ontology 1 and adjusting handle are stretched out in 9 part of regulating valve stem
13 connections.In practice, adjusting handle 13 is also replaced using regulation handle.
Specifically, the front-end configuration of the regulating valve stem 9 has a sealing element, regulating valve stem is adjusted by adjusting handle 13,
And then the folding amount between sealing element and valve body 10 is adjusted, the liquid or gas of the connectivity part of control bypass pipe 8 and tapered hollow pipe 3
The flow of body.When needing using 8 circulating liquid of bypass pipe or gas, regulating valve stem 9 leaves bypass pipe 8 and cone with dynamic seal
The connectivity part of shape hollow tube 3, so as to adjust the pressure difference of the import and export of the nonreturn valve core 4 in tapered hollow pipe 3.And works as and need to close
When closing the circulating function of bypass pipe 8, regulating valve stem 9 blocks the connection of bypass pipe 8 Yu tapered hollow pipe 3 with dynamic seal.
A fastening screw nut 14 is equipped between regulating valve stem 9 and adjusting handle 13.The fastening screw nut 14 adjusts hand to prevent
Wheel 13 falls off.
Pressure gauge explosion-proof leakage-proof quick breaker specific embodiment of the invention is, when the import and export pressure difference of nonreturn valve core 4
When equal, nonreturn valve core 4 is fallen after rise on flow adjusting screw rod 5；Flow adjusting screw rod 5 controls liquid or gas medium from check valve
Pass through uninterrupted between core 4 and tapered hollow pipe 3.When pressure gauge establishes pressure, nonreturn valve core 4 and tapered hollow pipe 3 it
Between gap it is too small, it is then too fast that nonreturn valve core 4 moves up speed, easily formation one direction shut-off state, and pressure gauge indicates pressure at this time
Distortion；And the gap between nonreturn valve core 4 and tapered hollow pipe 3 is excessive, when the micro leakage of pressure gauge, can not achieve and is automatically closed
A possibility that it is larger, therefore, according to different liquid or gas medium, the flow adjusting screw rod 5 for passing through setting controls check valve
Gap between core 4 and tapered hollow pipe 3.
With reference to Fig. 2, after opening pressure switch B, the work of nonreturn valve core 4 pressure difference and uninterrupted in tapered hollow pipe 3
The water outlet of tapered hollow pipe 3 is moved upward under, after the import and export pressure difference balance of tapered hollow pipe 3, nonreturn valve core
4 from top to down slowly fall.When generating certain pressure difference or flow when leakage or quick-fried table occur for pressure gauge A, nonreturn valve core 4
After contacting with 3 exit of tapered hollow pipe and realization is automatically closed.When the company of this pressure gauge explosion-proof leakage-proof quick breaker and pressure gauge A
When jointed tubular workpieces are longer, nonreturn valve core 4 easily forms one direction shut-off, and pressure gauge A cannot normally be shown, opens bypass pipe 8 at this time
Valve module of voltage regulation 15 to eliminate the pressure difference of the import and export of nonreturn valve core 4, and wait pressure gauge A show it is normal after, closing pressure-regulating valve
Component 15.In addition, valve module of voltage regulation 15 can also be used to eliminate when installing pressure gauge A for the first time or with pressure replacement pressure gauge A
The import and export pressure difference of nonreturn valve core 4, the state for being restored to out nonreturn valve core 4.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
