Abstract
The present invention discloses a kind of thin type gas pressure limiting valve, is spliced and formed by the floating piece for coating whole valve body above the support chip above valve seat, valve seat, the stator on support chip, the sealing lipid layer above stator and sealing lipid layer and both ends are connected with valve seat.General rounded, thickness is less than 5mm.It is an advantage of the invention that thickness of thin and easy to use, safe, pressure limiting precision is high, and manufacture craft is simple, and cost is relatively low, Opening pressure 300Pa, clossing pressure 20Pa, the Pa of pressure limiting precision 280, is adapted for mount on all kinds of soft package storage bags.
Description
Technical field
The present invention relates to safety valve class, particularly gas pressure limiting valve.
Background technology
Existing safety valve is hang down hammer, lever, spring and pilot-operated type by textural classification（Pulsed）；Press valve body structure
Closed and two kinds of Unseal type can be divided into by making.Pressure limiting valve is divided into two kinds of weight valve and spring valve, and its principle is to work as closed container
Interior air pressure reaches pressure limiting valve gravity（Or spring stiffness）When, pressure limiting valve starts pressure release, so as to reach internal pressure homeostatic process.Common
Limiting valve of pressure cooker category weight valve, gas tank safety valve category lever safety valve, drift boat air bleeding valve category spring valve etc..
Pulsed（Pilot-operated type）Safety valve is installed only on safety dischtrge very big boiler and pressure vessel at present.
The weight valve being made of metal such as limiting valve of pressure cooker is simple in construction, need to be disposed vertically；It is made up of metal or plastics
Spring loaded safety valve such as drift boat exhaust structure it is complicated, precision is not high；Pulsed（Pilot-operated type）Safety valve structure is complicated, peace
Filling required precision height can only positioned vertical.The thicker phenomenon of thickness be present in above-mentioned valve.
The content of the invention
It is an object of the invention to provide a kind of thickness of thin, pressure limiting precision height, and the thin type gas pressure limiting valve that Opening pressure is low.
Realizing the technical scheme of the object of the invention is：
A kind of thin type gas pressure limiting valve, above the support chip above valve seat, valve seat, the stator on support chip, stator
Whole valve body is coated above sealing lipid layer and sealing lipid layer and floating piece that both ends are connected with valve seat splices and formed.Typically in circle
Shape, thickness are less than 5mm.
Described valve seat and support chip, support chip and stator, bonded with neoprene adhesive.
The stomata of alignment is provided with stator, support chip and valve seat.
Floating piece steam vent is reference with stator 3 and is arranged diagonal with the steam vent of stator 3.Floating piece 1 is with fixing
100 ~ the 800cst of stop-leak compound kinematic viscosity irrigated between piece 3（25℃）Dimethicone.
A diameter of 3 ~ the 5mm of described steam vent.
It is an advantage of the invention that thickness of thin and easy to use, safe, pressure limiting precision is high, and manufacture craft is simple, and cost is relatively low,
Opening pressure 300Pa, clossing pressure 20Pa, the Pa of pressure limiting precision 280, it is adapted for mount on all kinds of soft package storage bags.
Brief description of the drawings
Fig. 1 is the structural representation of this thin type gas pressure limiting valve.
In figure, 1, floating piece；2nd, lipid layer is sealed；3rd, stator；4th, support chip；5th, valve seat.
Embodiment
Reference picture 1, pressure limiting valve of the present invention include valve seat 5 and floating piece 1 made of the good rubber coated fabrics of air-tightness,
Stop-leak compound 2, stator 3, support chip 4 form.Valve seat 5 is used with floating piece 1, valve seat and support chip 4 and stator 3 with support chip 4
The Chloroprene Rubber Adhesive bonding of cold curing.The stomata alignment of stator 3, support chip 4 and valve seat 5 during bonding.Floating piece is vented
Hole is reference with stator 3 and is arranged diagonal with the steam vent of stator 3.The close of 0.8g is irrigated between floating piece 1 and stator 3
Fat 2 is sealed, stop-leak compound is with kinematic viscosity 500cst（25℃）Dimethicone be advisable.
Described valve seat and support chip, support chip and stator, bonded with neoprene adhesive.
The a diameter of 4mm of described steam vent.
