Description
Technical field
The utility model relates to valve field, particularly relates to a kind of spring loaded breather valve.
Background technique
Inhalation valve safeguards that cartridge gas pressure balances, and reduce the energy-saving safe product of medium volatilization, inhalation valve makes full use of the bearing capacity of storage tank itself to reduce media discharge, and its principle utilizes the weight of positive/negative-pressure valve disc to control exhaust malleation and the intake negative-pressure of storage tank; When extracting medium out outward toward tank; make the pressure drop of the tank internal upper part gas space; when reaching the operation negative pressure of inhalation valve; the negative pressure valve disc backing down inhalation valve backs down by the air outside tank; ambient atmos is made to enter in tank; make the pressure in tank no longer continue to decline, allow in tank with the air pressure balance outside tank, protect the safety installations of storage tank.The working principle of inhalation valve is that the pressure of the tank internal upper part gas space is raised, and when reaching the operation malleation of inhalation valve, pressure valve is backed down when supplementing medium in tank, and gas, from the effusion of inhalation valve expiratory port, makes tank internal pressure not continue to increase; Air outside tank will back down the negative pressure valve disc of inhalation valve.
Model utility content
The utility model provides a kind of spring loaded breather valve, and under the elastic force effect of spring, the first valve block in inhalation valve, the second valve block are closed, and when device interior pressure surge, the first valve block, the second valve block can carry out adjustment action according to pressure extent.
The utility model is achieved through the following technical solutions:
A kind of spring loaded breather valve, comprise valve body, bonnet, spool, described bonnet has and is communicated with valve inner and extraneous connecting port, described spool comprises the first valve block, the second valve block, first valve block is against on valve body by the first spring, described first valve block is arranged porose, described second valve block is connected with connecting rod, and connecting rod is connected with the second spring, under the elastic force effect of the second spring, the second valve block covers aperture.
Described first valve block and valve body contact place are provided with sealing gasket.Sealing gasket strengthens the sealing effect of the first valve block and valve body, prevents device interior medium from leaking.
Described valve body there is flange plate, flange plate is provided with flange hole.Mounting flange assembly on flange plate and equipment, utilizes the flange hole on bolt and nut and flange plate to fix inhalation valve and equipment.
Be threaded connection between described bonnet and valve body.Utilization is threaded, simple and convenient during dismounting.
When device interior pressure increase, draught head to act on the downside of the first valve block and on the downside of the second valve block from device interior, first spring shrinks under pressure, there is space in the first valve block and valve body connection part, device interior gas is from the runner bonnet of space, then flow out from connecting port, thus equipment internal pressure reduces.
When device interior pressure reduces, draught head to act on the upside of the first valve block and on the upside of the second valve block from atmospheric side, second spring contraction, second valve block leaves the hole on the first valve block, thus hole connectivity device on the first valve block is inner and air, air access arrangement is inner, device interior pressure increase.
Compared with prior art, the beneficial effects of the utility model are: the first valve block of the present utility model, the second valve block and the first spring, the second spring interact, according to device interior and outside pressure difference, the air pressure in automatic regulating equipment, makes equipment internal air pressure and external balance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, connecting port; 2, the first spring; 3, connecting rod; 4, bonnet; 5, sealing gasket; 6, valve body; 7, flange plate; 8, the second spring; 9, the second valve block; 10, hole; 11, the first valve block.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of spring loaded breather valve, comprise valve body 6, bonnet 4, spool, described bonnet 4 has and is communicated with the inner and extraneous connecting port 1 of valve body 6, described spool comprises the first valve block 11, second valve block 9, first valve block 11 is against on valve body 6 by the first spring 2, described first valve block 11 arranges porose 10, and described second valve block 9 is connected with connecting rod 3, and connecting rod 3 is connected with the second spring 8, under the elastic force effect of the second spring 8, the second valve block 9 covers aperture 10.
Described first valve block 11 is provided with sealing gasket 5 with valve body 6 contacting point.Sealing gasket 5 strengthens the first valve block 11 and the sealing effect of valve body 6, prevents device interior medium from leaking.
Described valve body 6 there is flange plate 7, flange plate 7 is provided with flange hole.Flange plate 7 and the mounting flange assembly on equipment, utilize the flange hole on bolt and nut and flange plate 7 to fix inhalation valve and equipment.
Be threaded connection between described bonnet 4 and valve body 6.Utilization is threaded, simple and convenient during dismounting.
When device interior pressure increase, draught head to act on the downside of the first valve block 11 and on the downside of the second valve block 9 from device interior, first spring 2 shrinks under pressure, space is there is in the first valve block 11 with valve body 6 connection part, device interior gas is from space runner bonnet 4, then flow out from connecting port 1, thus equipment internal pressure reduces.
When device interior pressure reduces, draught head to act on the upside of the first valve block 11 and on the upside of the second valve block 9 from atmospheric side, second spring 8 shrinks, second valve block 9 leaves the hole 10 on the first valve block 11, thus hole 10 connectivity device on the first valve block 11 is inner and air, air access arrangement is inner, device interior pressure increase.
First valve block 11, second valve block 9 of the present utility model and the first spring 2, second spring 8 interact, and according to device interior and outside pressure difference, the air pressure in automatic regulating equipment, makes equipment internal air pressure and external balance.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
