Abstract
The utility model discloses a kind of thin type gas pressure limiting valve, is spliced by the floating piece for coating entire valve body above the support chip above valve seat, valve seat, the fixinig plate on support chip, the sealing lipid layer above fixinig plate and sealing lipid layer and both ends are connected with valve seat.General rounded, thickness is less than 5mm.The utility model has the advantages that thickness is 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, and 280 Pa of pressure limiting precision is adapted for mount on all kinds of soft package storage bags.
Description
Technical field
The utility model is related to safety valve classes, 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 by making.Pressure limiting valve is divided into two kinds of weight valve and spring valve, and 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 at present on safety dischtrge very big boiler and pressure vessel.
The weight valve being made of metal such as limiting valve of pressure cooker is simple in structure, need to be disposed vertically；It is made 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.There are the thicker phenomenons of thickness for above-mentioned valve.
Utility model content
The purpose of this utility model is to provide that a kind of thickness is thin, pressure limiting precision is high, and the thin type gas limit that Opening pressure is low
Pressure valve.
Realizing the technical solution of the utility model aim is：
A kind of thin type gas pressure limiting valve, by the support chip above valve seat, valve seat, the fixinig plate on support chip, fixinig plate
Coat entire valve body above the sealing lipid layer in face and sealing lipid layer and floating piece that both ends are connected with valve seat splice, generally in
Circle, thickness are less than 5mm.
The valve seat and support chip, support chip and fixinig plate are bonded with neoprene adhesive.
The stomata of alignment is equipped in fixinig plate, support chip and valve seat.
Floating piece gas vent is reference with fixinig plate 3 and is arranged diagonal with 3 gas vent of fixinig plate.Floating piece 1 is with fixing
100 ~ the 800cst of stop-leak compound kinematic viscosity being perfused between piece 3（25℃）Dimethicone.
A diameter of 3 ~ the 5mm of the gas vent.
The utility model has the advantages that thickness is thin and easy to use, safe, pressure limiting precision is high, and manufacture craft is simple, cost
Relatively low, Opening pressure 300Pa, clossing pressure 20Pa, 280 Pa of pressure limiting precision are adapted for mount on all kinds of soft package storage bags
On.
Description of the drawings
Fig. 1 is the structure diagram of this thin type gas pressure limiting valve.
In figure, 1, floating piece；2nd, lipid layer is sealed；3rd, fixinig plate；4th, support chip；5th, valve seat.
Specific embodiment
With reference to Fig. 1, the utility model pressure limiting valve includes the valve seat 5 made of the good rubber coated fabrics of air-tightness and floats
Piece 1, stop-leak compound 2, fixinig plate 3, support chip 4 form.Valve seat 5 and floating piece 1, valve seat and support chip 4 and fixinig plate 3 and support chip
4 are bonded with the Chloroprene Rubber Adhesive of room temperature curing.The stomata alignment of fixinig plate 3, support chip 4 and valve seat 5 during bonding.Floating piece is arranged
Stomata is reference with fixinig plate 3 and is arranged diagonal with 3 gas vent of fixinig plate.It is perfused 0.8g's between floating piece 1 and fixinig plate 3
Stop-leak compound 2, stop-leak compound is with kinematic viscosity 500cst（25℃）Dimethicone be advisable.
The valve seat and support chip, support chip and fixinig plate are bonded with neoprene adhesive.
The a diameter of 4mm of the gas vent.
