Description
Technical field
The utility model relates to bucket drain pumps, and in particular to a kind of for inflation exhaust one of the bucket on drain pump platen
Body valve.
Background technique
Bucket is in use with drain pump, in the poor medium of flow behavior, needs to assist applying to medium with platen
Pressure is slidingly sealed between rubber platen and bucket wall so that medium can smoothly enter into pump intake, thus initial platen into
Enter after bung hole also not in contact with to during this section of medium, in order to enter platen preferably in bucket, need by platen and medium it
Between air exhaust, platen decline touch medium after, to close degassing function, prevent medium from being squeezed out by platen pressure.?
After medium has been conveyed by pump in bucket, platen can touch a barrel bottom, during taking out platen out of bucket, because of bucket bottom air
Thin similar vacuum, is influenced, platen is not easy to take out by external atmosphere pressure！At this moment the sky only formed to platen and bucket bottom
Interior inflation can be only achieved inner and outer air pressure and unanimously take out platen.At present, it usually needs one exhaust outlet of design on platen, one
Valve will be arranged in inflating port, exhaust outlet, and check valve will be arranged in inflating port.Burp valve is used to open or closes degassing function,
Inflating port check valve prevents medium from flowing out, mechanism is complicated, troublesome in poeration for unidirectionally allowing inwardly inflation.
Utility model content
In order to solve the above-mentioned problems in the prior art, the utility model discloses a kind of barrel with drain pump platen
Inflate exhaust integratedization valve.
The technical solution adopted in the utility model is as follows: a kind of barrel of inflation exhaust integratedization valve with drain pump platen, packet

Mouth under body.
Preferably, position is valve rod between spool upper and lower limits part, for moving up and down in spool bore.
Preferably, inflation exhaust port and spool venthole upper end are in the setting that is staggered.
The utility model has the beneficial effects that:
1. the utility model is by being combined into one for exhaust outlet, burp valve, inflating port, the check valve etc. on existing platen
Body reduces manual operation number only with a valve body, and use is more convenient.Valve opening passes through under platen when closing valve, inflation after exhaust
Drop and pneumatic operation are automatically performed, and prosthetic participates in, and are avoided medium and human contact, are enhanced the safety of equipment.With it is existing
There is technology compared to saving ball valve, check valve, be combined into one, structure is simple, convenience easy to use, the processable self-control of common machine.
2. the utility model is cooperated by that will form sealing surface 2 and the peripheral of sealed end panel at 3 lower mouthfuls of inner walls of valve body
Using being sealed, spool moves up and down in valve body, when valve core outer surface touches medium, in the reaction force of dielectric surface
Under, it moves up, eventually arrives at closed position, at this moment seal spool end plates periphery generates sealing with mouth inner wall surface under valve body
Face, the high viscosity medium of salable firmly poor fluidity.
3. being that valve rod and valve body internal valve core bore generate sliding motion in the middle part of the utility model spool, the sliding contact surface is for valve
Straight-line guidance when core slides.
4. there are certain distances between venthole and valve deck inflation exhaust port in the utility model spool, and are staggered and open up
It sets, not on the same line, effectively prevent some magazines when exhaust to enter intratracheal.
5. 5 area of positioning large washer of the utility model spool upper end exceeds spool bore outer diameter, enough areas are provided,
Enough thrust is generated when to inflate to push spool to move down, and be able to enter compressed air in bucket.
Detailed description of the invention
Fig. 1 the utility model inflates exhaust integratedization valve closing structure schematic diagram；
Fig. 2 the utility model inflates exhaust integratedization valve and opens exhaust condition structural schematic diagram.
In figure: 1- spool, 2- sealing surface, 3- valve body, 4- spool bore, 5- large washer, 6- spring washer, 7- locknut, 8- valve deck, 9-

Specific embodiment
The utility model is further explained and is illustrated with reference to the accompanying drawing；
As shown in Figure 1, a kind of barrel of inflation exhaust integratedization valve with drain pump platen, including drain pump staving, platen position
It is used cooperatively in matched in the staving, tubular valve body 3 is cased on platen, and 3 lower end of tubular valve body and flat platen bottom face are matched
Joint, the suitable for reading of valve body 3 is covered with valve deck 8, and the two is fixed together by bolt 10, and inflation row is provided on valve deck 8
Gas interface 11 is divided into upper and lower chamber by partition inside valve body 3, is equipped with spool bore, spool bore internal diameter and spool 1 in the middle part of partition
Outer diameter matches.Spool wears the people hole, is located at the position of the hole upper and lower on spool and is respectively equipped with locating part, spool is upper and lower
Position between locating part is valve rod, can be moved up and down in spool bore, and spool bore inner wall is the sliding surface with valve stem contacts, spool
Lower end be sealed end panel, the inner wall of the lower mouth of tubular valve body 3 is that sealing surface 2 and the periphery of sealed end panel are used cooperatively, valve
In-core is equipped with the venthole 12 of T-type or right-angled intersection, and upper and lower chamber is made to be connected.When spool moves up, the lower mouth of tubular valve body 3
When with the peripheral bond of sealed end panel, closed lower chambers are formed, the gas entered from inflation exhaust port passes through venthole
12 enter lower chambers.Inflation exhaust port 11 and 12 upper end of spool venthole are in the setting that is staggered.Spool upper limit part is installation
Locknut 7 on spool top.The periphery of 7 lower section spool of locknut is connected with slide opening sealing element, and slide opening sealing element is by spring washer 6 and spool
It positions large washer 5 to form, spring washer 6 is clipped between positioning large washer 5 and locknut 7, when spool moves down, by positioning large washer 5
It prevents spool from continuing to move down, while closing the gap between spool and spool bore upper end.The lower limit part of spool is spool lower part
The positive stop lug boss that peripheral overstriking is formed.
In use, realizing positioning and guiding when the spool bore 4 of the utility model moves up and down spool, spool 1 is to moving down
Dynamic stroke is positioned by large washer 5.1 lower end surface plate 13 of spool cooperates with 3 lower mouthfuls of sealing surfaces of valve body 2, realizes to medium in bucket
Buffer action, when the sealed end panel 13 of spool 1 touches dielectric surface in bucket, in the promotion of dielectric surface reaction force
Under, spool 1 can be moved to closed state, as shown in Figure 1.When platen needs take out out of bucket, as shown in Fig. 2, passing through inflation
Exhaust port 11 is passed through compressed air into valve body upper chamber, and compressed air upper port of venthole 12 out of spool 1 enters valve
3 bottom chamber of body applies pressure to 1 sealed end panel 13 of spool, pushes bottom spool 1 that can be pushed out in the pressure of compressed air, under
Chamber is opened, and compressed air can be entered in bucket by venthole 12, convenient for easily taking out platen.
When to convey medium in new bucket, as shown in Fig. 2, spool is for opening exhaust condition, at this moment platen enters
In bucket, the air in bucket between medium and platen can enter 3 lower chambers of valve body, enter upper chamber through the venthole 12 on spool 1
It is discharged to outside bucket from inflation exhaust port 11, when platen, which drops to, touches dielectric surface in bucket, spool is closed, and is repeated
The above process.
