Abstract
The present invention relates to a kind of shut-off valves with service valve, including valve body, flap, valve rod, valve deck, handwheel, it is characterized in that two shut-off valves are arranged in a valve body, one of shut-off valve puts into normal operating conditions, another shut-off valve is in normally open, when in running order shut-off valve breaks down, another shut-off valve is devoted oneself to work, and is kept pipe-line system continuous operation, is eliminated bypass duct system, installation equipment is saved, has many advantages, such as installation space, at low cost.
Description
Technical field
The invention belongs to valve field more particularly to a kind of shut-off valves.The present invention is suitable for plus the A grades of pipelines such as hydrogen, chlorine
System.
Background technique
In adding the A such as hydrogen, chlorine grades of pipe-line system, since medium pipeline does not allow to stop working, multiple line pipe is generally used
Road pumped (conveying) medium is opened by-pass line, is overhauled under the normal delivery situation of medium to valve when valve breaks down.
Its major defect is that multiple line by-pass line system needs to install more valves, and installation space is big, and equipment installation cost is high.
Summary of the invention
The present invention in view of the shortcomings of the prior art, provides the band service valve that a kind of equipment installation space is small, installation cost is low
Shut-off valve.
Technical solution of the present invention includes valve body, flap, valve rod, valve deck, handwheel, it is characterized in that being formed in body cavity
One valve seat and the second valve seat, flap include the first flap and the second flap, and valve rod includes the first valve rod and the second valve rod, valve deck packet
The first valve deck and the second valve deck are included, handwheel includes the first handwheel and the second handwheel；First valve seat and the first flap, the first valve rod,
First valve deck, the first handwheel form the first shut-off valve, the second valve seat and the second flap, the second valve rod, the second valve deck, the second handwheel
Form the second shut-off valve.
In above technical scheme, the outlet of the first valve seat is connected to valve outlet channel, and import and the outlet of the second valve seat connect
Logical, the second valve seat import is connected to valve body import channel.
In above technical scheme, the first valve seat is arranged concentrically with the second valve seat.
The beneficial effects of the invention are as follows two shut-off valves are arranged in a valve body, one of shut-off valve puts into normal work
Make state, another shut-off valve is in normally open, when in running order shut-off valve breaks down, another shut-off valve
Devote oneself to work, keep pipe-line system continuous operation, eliminate bypass duct system, save installation equipment, have installation space,
The advantages that at low cost.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Shut-off valve with service valve as shown in Figure 1, including valve body 1, flap, valve rod, valve deck, handwheel；In 1 inner cavity of valve body
It is formed with the first valve seat 3 and the second valve seat 8, flap includes the first flap 4 and the second flap 10, and valve rod includes the first valve rod 5 and the
Two valve rods 11, valve deck include the first valve deck 6 and the second valve deck, and handwheel includes the first handwheel 7 and the second handwheel 12；First valve seat 3
The first shut-off valve, the second valve seat 8 and the second flap are formed with the first flap 4, the first valve rod 5, the first valve deck 6, the first handwheel 7
10, the second valve rod 11, the second valve deck, the second handwheel 12 form the second shut-off valve, the first valve seat 3 and the second valve seat 8 using in valve
1 inner cavity pile-up welding hard alloy of body is formed, and the first flap 4 has and the mutually matched sealing surface of the first valve seat 3, the second flap 10 tool
Have with the mutually matched sealing surface of the second valve seat 8, stuffing seal, the second valve are set between the first valve deck 6 and the first valve rod 5
Stuffing seal is set between lid and the second valve rod 11；When one of shut-off valve is in running order, another cut-off
Valve is in normally open, and when one of shut-off valve breaks down, another shut-off valve is devoted oneself to work, and pipe-line system is kept to connect
Continuous work.
The outlet of first valve seat 3 is connected to the exit passageway 2 of valve body 1, import and 8 outlet of the second valve seat, the second valve seat 8
Import is connected to the intake channel 9 of valve body 1.
First valve seat 3 is arranged concentrically with the second valve seat 8, i.e. the center line weight of the center line of the first valve seat 3 and the second valve seat 8
It closes.
