It connects.Under normality, pressure releasing valve core is in rear end by elastic force effect, and diaphragm seal closes pressure release valve seat, plays the role of ending fluid.When
When the Upstream section pressure of pressure release passage increases to the elastic force more than pressure release spring, fluid will push entire pressure release by diaphragm seal
Spool is mobile to the tract direction of pressure releasing valve core, i.e. pressure release passage, makes to occur between diaphragm seal and pressure relief valve body front opening
Gap, fluid can be discharged from the gap to pressure release passage tract.After the pressure decline of equal pressure release passages Upstream section, pressure release
Pressure releasing valve core is retracted reset again by spring, is restored the cut-off to pressure release valve seat and is acted on.
Preferably, the front end of pressure release valve seat is horn mouth, horn mouth front openings diameter is greater than rearward openings diameter；It lets out
The front end of pressure valve core is close to be equipped with the recessed sealing ring mounting groove of a circle on rear side of diaphragm seal, and adaptation is equipped in sealing ring mounting groove
Elastic seal ring；The outer diameter of elastic seal ring is greater than the horn mouth front openings diameter of pressure release valve seat, opens less than horn mouth rear
Mouth diameter.This is designed as a sealing structure.The downstream of pressure release valve seat is designed as it is tubaeform, in the downstream of pressure releasing valve core
It is close to be mounted with a circle elastic seal ring on rear side of diaphragm seal, preferably can be adapted to sealing with tubaeform inner sidewall.
Preferably, the tract of the pressure release passage is stepped hole, the front end of stepped hole is smaller diameter end, and rear end is big
Diameter end；The rear end of installation passage and pressure release passage tract stepped hole is coaxial and equal diameter.Using stepped hole as pressure release passage
Downstream, the cascaded surface that can use stepped hole forms limit to pressure release valve seat, can help installation personnel in assembly
Quickly positioning is played the role of accelerating installation.
Preferably, the tract of pressure release passage is confined space, it is spatially provided with the relief hole for being connected to the space external world.
Relief hole can cooperate with pressure release spring to be used to adjust pressure release flow.
The present apparatus can be applied under pressure fluid, the two different working environments of pressed gas.
As preferably one of, be equipped in relief hole flow monitoring probe.If present apparatus use in pressure fluid environment,
The flow and flow rate of pressure release can be then monitored by flow monitoring probe.
As two preferably, the zufolo that can be pushed by air-flow is installed in relief hole.If present apparatus use is in pressure gas
Body environment, more direct method are one zufolos of installation on relief hole, and the air-flow for flowing through zufolo is bigger, and birdie is louder, gas
Stream is more anxious, and birdie is higher.Pressure release signal effectively can be passed into operator in this way.
In conclusion the beneficial effects of the utility model are: having integrated assembling structure, it may be convenient to whole to tear open
Dress, to reduce expenditure of time when assembly and maintenance.

Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing.
Embodiment as shown in Figure 1 is that one kind transfinites decompression alarming apparatus, is applied on certain pressed gas valve.This example
The decompression alarming apparatus that transfinites is equipped with pressure release passage 1, and pressure release passage is L shape, and it is laterally tract that L-shaped, which is vertically Upstream section,.Peace
It fills channel 2 and the tract of pressure release passage is coaxially connected, keep installation passage and pressure release passage shape at T-shaped, then the vertical of T shape is to let out
The Upstream section of pressure passageway, left section of the transverse direction of the T shape tract for pressure release passage, right section of the transverse direction of T shape is installation passage.Pressure release is logical
The tract in road is stepped hole, and the front end of stepped hole is smaller diameter end, and rear end is larger diameter end；Under installation passage and pressure release passage
Swim section stepped hole rear end is coaxial and equal diameter, disposably pressure relief valve body can be installed to T shape from rear end by installation passage
Transverse direction and vertical intersection, to realize quickly positioning.Pressure relief valve body includes the pressure release valve seat 3 positioned at outside, this example
Middle pressure release valve seat is closely plugged on anchor point by interference fit.Pressure release valve seat is stepped hole, and front end is less than rear end；Relief valve
It is connected on the side wall of seat with the Upstream section of pressure release passage.Pressure releasing valve core 4 is that can be adapted to the rod piece being plugged in pressure release valve seat, pressure release
The front end of spool is that the left end illustrated is the diaphragm seal 5 that diameter is greater than relief valve base rear end opening, and the rear end of pressure releasing valve core is schemed
The right end protrusion shown is equipped with spring retainer piece 6；Pressure release spring 7 is socketed on pressure releasing valve core, and one end is connected to spring retainer piece
On, the other end is connected on the cascaded surface of pressure release valve seat.The front end of pressure release valve seat is horn mouth, and horn mouth front openings diameter is big
In rearward openings diameter；It is close to be equipped with the recessed sealing ring mounting groove 8 of a circle, sealing ring on rear side of diaphragm seal in the front end of pressure releasing valve core
Adaptation is equipped with elastic seal ring 9 in mounting groove；The horn mouth front openings that the outer diameter of elastic seal ring is greater than pressure release valve seat are straight
Diameter is less than horn mouth rearward openings diameter.The tract of pressure release passage is a confined space, is spatially provided with and is connected to outside space
The relief hole 10 on boundary.Since the present apparatus is applied in high pressure gas working environment, being equipped in relief hole can be by air-flow
The zufolo 11 of promotion.
Under normal conditions, the air pressure of pressure release passage Upstream section is less than the elastic force of pressure release spring, and pressure release spring pulls pressure releasing valve core
Positioned at the rightmost side, diaphragm seal sealing covering pressure release valve seat front opening realizes sealing effect, state at this time is as shown in Figure 1.When
When the air pressure of pressure release passage Upstream section is greater than the elastic force of pressure release spring, gas pushes pressure releasing valve core to overcome pressure release bullet by diaphragm seal
The elastic force of spring is moved to the left, and makes occur gap, the gas of pressure release passage Upstream section between diaphragm seal and pressure release valve seat front opening
Pressure release passage tract can be flowed to from the channel.State at this time is as shown in Figure 2.Being equipped in relief hole can be by air-flow
The zufolo of promotion, the air-flow for flowing through zufolo is bigger, and birdie is louder, and air-flow is more anxious, and birdie is higher, as long as monitoring personnel hears the whistle
Sound just can know that decompression alarming apparatus in pressure release, and can judge the size and emergency of pressure release air-flow by birdie.
