Compact-sized, fluid proof seal is good, service life length.
In pipe applications, the wherein valve element in the first valve element 204 and the second valve element 304 is carried out double-safety valve of the present invention
Normal to open and close work, another valve element is in the armed state of standard-sized sheet, when always work valve element and corresponding valve rod due to
When long-term operation occurs wearing and can not reach technological requirement and normally open and close, take turns to it and be in normally open, another shape of awaiting orders
The valve element input of state is normal to be opened and closed in work, and to ensure pipeline normal work, double-safety valve has two-way safeguarding function so that pipeline
Can long-term normal work, improve industrial security and production efficiency, it is manufactured bigger economic benefit.
One ball valve is normally only installed in conventional pipelines, once ball valve breaks down, then needs halt device to work, is suspended
Pipeline works and empties pipeline, could carry out repair and replacement, and maintenance difficulty is big, and maintenance cost is high, delays industrial life
Production, influences production efficiency, or even leaks out harmful fluids and pollute environment, and in order to solve prior art problem, improve pipeline
Security, feature, continuation, the permanence used, it will usually two ball valves are bolted together by flange and are installed to again
On pipeline, one ball valve carries out switching manipulation, and another ball valve is shown in a fully open operation, once one ball valve breaks down, also has another
One ball valve carries out normal work to ensure pipeline normal use, the structure for so using two ball valve assembly to be used together, zero
Part is more, and manufacturing cost is high, ball valve entire length length, occupies that installing space is big, and installation site has certain limitation, is applicable model
Enclosing is restricted, while two ball valves are attached fixation, and with usage time leakage accident, or even meeting easily occur for junction
Unthinkable adverse consequences is caused, economic loss is caused directly to user.
The present invention proposes a kind of double-safety valve of monoblock type, is led with solving only one ball valve of single setting in conventional pipelines
The problems such as maintenance difficulty of cause is big, and maintenance cost is high.Double-safety valve of the present invention includes the valve body provided with dual valve pocket, and valve body is by complete
Holohedral symmetry identical left valve barrel 201 and right valve barrel 301 are connected as one by a conduction pipe 100, left valve barrel 201, conduction pipe
100th, right valve barrel 301 is arranged to integrated formed structure, reasonable in design, compact-sized, and fluid proof seal is good, and left valve barrel 201
Side extends outwardly out one first connecting seat 214, and the side of right valve barrel 301 extends outwardly out the second connecting seat 314, valve body and first
Connecting seat 214, the second connecting seat 314 are arranged to integrated formed structure, and double-safety valve entire length immobilizes, later stage dismounting nothing
Duct length need to be adjusted, it is convenient and swift, while valve body sophisticated design in given size, integrally casting shaping, structural strength have
Ensure, process and assemble is convenient and swift, and abandons used flange when two traditional ball valves connect, and reduces making for parts
With, saving former material cost, simplified assembling procedure, reduction manufacturing cost；And the valve body provided with dual valve pocket is arranged to monoblock type
Structure, it is compact-sized, valve body entire length is substantially reduced, two ball valves only take up the sky of a ball valve when being installed compared with traditional structure
Between, for the pipeline of installing space deficiency the double-safety valve of the present invention can be installed easily, save installing space, expand and be applicable model
Enclose；Other dual valve pocket includes the first valve pocket 203 in left valve barrel 201, is connected with the first valve pocket 203 and be located at right valve barrel
The second valve pocket 303 in 301, the first valve pocket 203 are connected with the second valve pocket 303 by conduction pipe 100, and double-safety valve also wraps
Include the first valve element 204 being embedded in the first valve pocket 203, the first stem structure, the second valve element being embedded in the second valve pocket 303
304th, the second stem structure, double-safety valve are arranged to bivalve cored structure, when the first valve element 204 is in normal work, the second valve element
304 are in the armed state of standard-sized sheet, once being broken down at the first valve element 204, the second valve element 304 can start normal work immediately
To make, the second valve element 304 effectively makes up the deficiency of the first valve element 204 so that pipeline normal work, double-safety valve service life length,
And there is double insurance effect to pipeline, effectively improve security, feature, continuation, permanence that pipeline uses, it is ensured that work
Industry produces long-term normal work, improves efficiency；In addition, valve body is provided with the first mounting platform 202, the second mounting platform 302, the
One mounting platform 202, the second mounting platform 302 and valve body are arranged to integrated formed structure, and simple in construction, process is simple, production
