Specific implementation mode
As shown in Fig. 1 ~ Fig. 4, a kind of Double-seal valve, including valve body 1, spool 2 and valve deck 3, valve body import is equipped on valve body 1
6 and valve outlet 7, up big and down small truncated cone-shaped valve chamber is provided in valve body 1, and spool 2 is the truncated cone-shaped being harmonious with the valve chamber shape
Ontology, spool 2 are mounted in the valve chamber of valve body 1, then valve deck 3 are mounted on to the upper surface of valve body 1, and in valve deck 3 and spool 2
Between be provided with and prevent the elastic pressure parts that move up of spool 2, to limit the upward movement of spool 2.Valve is equipped in 2 ontology of spool
In-core chamber 8 is equipped with core assembly 11 in the bottom surface of spool 2, valve component 12 is equipped on the valve body 1 opposite with 2 bottom surface of spool,
Core assembly 11 is matched with valve component 12, is constituted through 2 rotary opening and closing valve core cavity 8 of spool and the second of valve outlet 7
Open and close valve 14, second opens and closes valve 14 there are many embodiment, can be shut-off valve, gate valve, ball valve, plate valve ... etc..In valve body 1
2-5 valve body ports 9 are provided on side wall, valve body port 9 is connected with valve body import 6, and quantity is provided on the side wall of spool 1
The spool port 10 of valve body port 9 is corresponded respectively to position, spool port 10 is connected with valve core cavity 8, spool port 10
It is matched with valve body port 9, constitutes and valve 13 is opened and closed with the first of valve body import 6 by 2 rotary opening and closing valve core cavity 8 of spool.The
It is all to realize that it is opened and is closed by the rotation of spool 2 that one keying valve 13 and second, which opens and closes valve 14, so first opens and closes valve 13
With the second keying valve 14 synchronous opening/closing is kept in 2 rotation process of spool.
To enable external impetus to control spool 2, it is equipped with upright shaft 4 at the top of spool 2, shaft 4 is from valve deck 3
Core bore in be pierced by, external power such as human hand or motor pass through rotation of the shaft 4 with movable valve plug 2.The core of shaft 4 and valve deck 3
There are gaps between hole, so come the gap between sealing pivot and core bore equipped with sealing mechanism 5 in the gap, prevent fluid from this
Gap is flowed out, and sealing ring or mechanical seal can be selected in sealing mechanism 5.
As shown in Figure 1, in the first embodiment of the present invention the second keying valve, second opens and closes valve 14 for plate valve, directly
It is made of the bottom surface and the bottom surface of valve body 1 of spool 2, the bottom surface of spool 2 is core assembly 11, and the bottom surface of valve body 1 is valve component
12, there are several vertical through hole being distributed around 2 rotation center of spool on core assembly 11, there is quantity and position on valve component
Vertical through hole identical with core assembly.The bottom surface of valve body 1 and the bottom surface of spool 2 are bonded to each other, and vertical when 2 bottom of spool is led to
Hole overlaps with the vertical through hole of 1 bottom of valve body when being connected to, and valve body port 9 also overlaps with spool port 10 and is connected to, double
Envelope valve is in open state, and fluid enters valve core cavity 8 by valve body import 6, valve body port 9, spool port 10, then passes through
The outlet of 2 bottom of spool and the outlet of valve component 12 flow into valve outlet 7, finally flow out Double-seal valve；When 2 bottom of spool
When vertical through hole and the vertical through hole of 1 bottom of valve body mutually stagger, valve body port 9 is also mutually staggered with spool port 10, double envelopes
Valve is in closed state.
As shown in Fig. 2, in second of embodiment of the present invention the second keying valve, the second keying valve 14 is shut-off valve,
Core assembly 11 is specially a stopper rod 15, and valve component 12 has a support construction and outlet, 15 top half of stopper rod to carry
Screw thread, lower half portion are prism, and lower end is fixed with circular slab, and 15 top of stopper rod is threaded in the bottom of spool 2, rib
Post part, which is worn, to be connected in the support construction of valve component 12, makes stopper rod that can only be moved up and down in valve component 12.Spool 2
Rotation drive stopper rod 15 move up and down, when stopper rod 15 be in extreme higher position, first open and close valve 13 spool port 10 and
Valve body port 9 is interconnected, and Double-seal valve is in open state；When stopper rod 15 is in extreme lower position, 15 end of stopper rod
Circular slab blocks the outlet of valve component 12, and the second keying valve 14 is in closed state, valve body port 9 and 10 phase of spool port
It is mutually staggered, the first keying valve 13 is also at closed state, and valve realizes two-stage sealing.
As shown in figure 3, in the third embodiment of the present invention the second keying valve, the second keying valve 14 is gate valve, valve
Core assembly 11 includes flashboard 16 and is fixed on the screw rod 17 that 2 bottom of spool is rotated with spool 2, has a straight trough, lock on valve component 2
Plate 16 is mounted in the straight trough of valve component 12 and perpendicular to the direction of valve outlet 7,16 top of flashboard by threaded hole with
17 screw-thread fit of screw rod, flashboard 16 can only be moved up and down with being rotated in straight trough for spool 2.When flashboard 16 is in extreme lower position,
Valve outlet 7 is sealed, the second keying valve 14 is at closed state, and the first keying valve 13 is also at closed state at this time, double
It seals valve and realizes dual-seal；When flashboard 16 is lifted to extreme higher position with the rotation of spool 2, first opens and closes the valve body port of valve 13
9 are interconnected with spool port 10, and Double-seal valve is in open state.
As shown in figure 4, in the 4th kind of embodiment of the present invention the second keying valve, the second keying valve 14 is ball valve, valve
Core assembly 11 is specially sphere 18, has a circular slot, sphere 18 to be mounted in the slot of valve component 12 on valve component 12, ball
There is a through-hole in body 18, in same level, 18 top of sphere is fixed on the axis of through-bore axis and valve outlet 6 by bar
The bottom of spool 2 makes sphere 18 be rotated together in company with spool 2.When the through-hole of sphere 18 is overlapped with valve outlet 6, two valves
Body port is also overlapped with 9 two spool ports 10, and Double-seal valve is in open state；Spool turns over 90 degree, 18 through-hole of sphere and valve
Body outlet 6 is staggered 90 degree, and valve body port 9 is also staggered 90 degree with spool port 10, and Double-seal valve is in closed state.
The present invention opens and closes valve 14 to realize that two-stage seals by the first keying valve 13 and second, and first opens and closes 13 closed group of valve
At sealing surface fitting it is close, area is big, after can bear prodigious Fluid pressure, the pressure that the second keying valve 14 is born will
Very little even without.This design has carried out two-stage sealing to fluid, and the leakproofness of valve and stability is made to greatly improve, and uses
Service life increases, and is suitable for various pipeline occasions.
