Description
Technical field
The utility model is related to a kind of pressure reducing valve more particularly to a kind of diaphragm type pressure-reducing valves.
Background technology
Present some factory floors and Modern Laboratory etc. are required for the design of gas pipeline, gas supply pipe system to exist
It wherein occupies an important position, whether its design rationally will to the accuracy of the normal operation of work and laboratory experiment result
It has a direct impact, security risk can be substantially reduced in profession, rational gas supply pipe system, moreover it is possible to convenient to carry out day
Often maintenance and maintenance.
It is existing that the working environment for using gas is needed usually to put many gas bombs indoors, one is carried out to equipment
One gas supply, the environment that gas bomb is concentrated is there are great security risk, and some gas or poisonous and hazardous seriously threatens
The personal safety of staff, secondly gas supply, which interrupts, can all bring huge economic loss, especially current most of laboratories
Gas supply different from general factory floor requirement, show that instrument and equipment is higher to the purity requirement of gas first,
Secondary various analytical instrument such as chromatograph or mass spectrograph are required for continuously using gas, and the supply of gas must be continuous, and output pressure is flat
Surely, the pressure oscillation of gas may cause instrument and equipment can not work normally, and the discontinuous supply of gas possibly even leads to instrument
Device equipment fault, therefore the design of laboratory air pipeline must be very strict.It requires consideration for how these gases being supplied to
It, can be with high-pressure cylinder, liquid Dewar bottle, central gas supply system or in summary several method is supplied in laboratory.
Utility model content
The utility model provides one kind simple in structure, reduction security risk, easy to operate, valve in order to solve problem above
Door open and close control is accurate, installation is easy to clean, good airproof performance, keying fast, stable, the with long service life diaphragm type of speed subtract
Pressure valve.
The technical solution of the utility model is：The valve includes valve body, connecting rod, inner cavity, spring, valve deck, diaphragm, valve
In valve body both sides, the valve body is in round vase shape for seat, spool, adjusting nut and pedestal, the air inlet and gas outlet setting,
The spool is arranged in valve body between air inlet and gas outlet, and the pedestal is arranged in body base, the spool
It can move up and down in pedestal, on valve body top, adjusting nut setting is described in body top for valve deck setting
Adjusting nut lower part couple coupler link, the spring is arranged on the connecting rod in valve deck, the connecting rod lower tip
Equipped with diaphragm, the diaphragm follows spring and connecting rod to move up and down in valve body.
The utility model is simple in structure, reduce security risk, is easy to operate, valve opening and closing control is accurate, installation cleaning side
Just, good airproof performance, open and close speed it is fast, stable, service life is long.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
1 is valve body in figure, and 2 be connecting rod, and 3 be inner cavity, and 4 be spring, and 5 be valve deck, and 6 be diaphragm, and 7 be valve seat, and 8 be spool, 9
It is adjusting nut, 10 be pedestal.
Specific implementation mode
A kind of diaphragm type pressure-reducing valve, the valve include valve body 1, connecting rod 2, inner cavity 3, spring 4, valve deck 5, diaphragm 6, valve
Seat 7, spool 8, adjusting nut 9 and pedestal 10, the air inlet and gas outlet are arranged in 1 both sides of valve body, and the valve body 1 is in
Round vase shape, the spool 8 are arranged in valve body 1 between air inlet and gas outlet, and the pedestal 10 is arranged at 1 bottom of valve body
Portion, the spool 8 can move up and down in pedestal 10, and the valve deck 5 is arranged in 1 top of valve body, the adjusting nut 9
Setting couples coupler link 2 in 1 top of valve body, 9 lower part of adjusting nut, and the company in valve deck 5 is arranged in the spring 4
On bar 2,2 lower tip of connecting rod is equipped with diaphragm 6, and the diaphragm 6 follows spring 4 and connecting rod 2 to be transported up and down in valve body 1
It is dynamic.
Above example is only to illustrate the invention and not limits technical solution described in the invention；Cause
This, is although this specification has been carried out detailed description with reference to above-mentioned each embodiment to the invention, this field
It is to be appreciated by one skilled in the art that still can modify to the invention or equivalent replacement；And all do not depart from this
The technical solution of the spirit and scope of innovation and creation and its improvement should all cover the right in the invention
In.
