Abstract
The utility model is a kind of snap joint.Include plug screw, spring, cone valve, valve seat, arc expansion tube, matrix, wherein arc expansion tube is installed in the top of matrix, valve seat is installed in the top of arc expansion tube, the bottom of valve seat is provided with taper hole and damping hole, cone valve is installed on taper hole, plug screw is installed in the top of valve seat, and plug screw is provided with water inlet, and spring is equiped between cone valve and plug screw.Joint of the present utility model is under the premise that security is guaranteed, easy to operate, and upper water is quick, time saving, laborsaving.
Description
Technical field
The utility model is a kind of snap joint, and particularly a kind of train water tank, which adds water, uses snap joint, belongs to and quickly connects
The innovative technology of head.
Background technology
Existing train water tank joint used when adding water is typically all to be connected using screw thread with train water tank, and what it was present lacks
Point is troublesome poeration, is wasted time and energy.
The content of the invention
The purpose of this utility model is to consider above mentioned problem and provide a kind of snap joint.Joint of the present utility model exists
Easy to operate on the premise of ensureing safety, upper water is quick, time saving, laborsaving.
The technical solution of the utility model is：Snap joint of the present utility model, includes plug screw, spring, cone valve, valve
Seat, arc expansion tube, matrix, wherein arc expansion tube are installed in the top of matrix, and valve seat is installed in the top of arc expansion tube,
The bottom of valve seat is provided with taper hole and damping hole, and cone valve is installed on taper hole, and plug screw is installed in the top of valve seat, and plug screw be provided with into
The mouth of a river, is equiped with spring between cone valve and plug screw.
The utility model compared with prior art, has the following advantages that：
1）The utility model water pipe head relies on the deformation of elastomer, tensioning is realized, in order that note hose coupling reliably blocks
Tightly, water tank inlet also makes corresponding arc-shaped concave.
2）Elastomer on the utility model joint, tensioning can either be deformed under pressure, and contracting is deformed after pressure release
Return, but still have certain support stiffness, it is ensured that joint has certain rigidity.
3）Spring is equiped between the utility model cone valve and plug screw, cone valve passes through institute on check valve equivalent to check valve
Some springs adjusts the Opening pressure of check valve, and can be by controlling the Deformation control clamping force of elastomer.
The utility model is a kind of ingenious in design, easy to operate, function admirable, convenient and practical snap joint.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment：
Structural representation of the present utility model is as shown in figure 1, snap joint of the present utility model, includes plug screw 1, spring
2nd, cone valve 3, valve seat 4, arc expansion tube 5, matrix 7, wherein arc expansion tube 5 are installed in the top of matrix 7, and valve seat 4 is installed in
The top of arc expansion tube 5, the bottom of valve seat 4 is provided with taper hole and damping hole 6, and cone valve 3 is installed on taper hole, and plug screw 1 is installed in
The top of valve seat 4, and plug screw 1 is provided with water inlet, and spring 2 is equiped between cone valve 3 and plug screw 1.
For ease of operation, quick connection is realized, is connected through a screw thread between above-mentioned plug screw 1 and valve seat 4.
In the present embodiment, connected between above-mentioned arc expansion tube 5 and matrix 7 using heat cure mode or using bonding
Mode is connected.
In the present embodiment, connected between above-mentioned valve seat 4 and arc expansion tube 5 using heat cure mode or using bonding
Mode is connected.
Snap joint of the present utility model be one kind can the tight self-detaching water filling joint of automatic expanding, its operation principle is such as
Under：When water filling main valve, which is switched, closes, the closed check valve being made up of the plug screw 1 with through hole, spring 2, cone valve 3, valve seat 4,
Water filling joint inserts the water inlet of water tank, and due to not having water in pipe, arc expansion tube 5 is collapsible, it is easy to insert entering for water tank
The mouth of a river.Then water filling main valve switch is opened, hydraulic pressure is less than the opening pressure of check valve during beginning, under the effect of this hydraulic pressure, arc
Expansion tube 5 is expanded, and is stuck in the arc-shaped concave of water tank inlet, and water injection pipe is locked, as hydraulic pressure is raised, and is opened cone valve 3, is opened
Beginning water filling.After water filling is finished, the water closed in water filling main valve switch, pipe shrinks arc expansion tube 5 by the pressure release of damping hole 6,
Water filling joint is easy to deviate from out of water tank inlet arc-shaped concave.In addition, water filling main valve can pass through wireless remote control mode list
Only or concentration is opened and closed.
