Interior, it is connected with the minor diameter key above bolt, and spring is provided between the two, and the valve element is in water pressure and spring force phase
Slided up and down in cavity under interaction, so as to realize the break-make of current.
Wherein, the valve element is made up of switch portion and connecting portion, and the connecting portion bottom surface is provided with blind hole, with minor diameter bolt
Body phase is connected.
Wherein, the diameter of the discharge orifice is between switch portion and connecting portion diameter.
Wherein, pad is accompanied between the bonnet and valve body.
Wherein, the water hole number on the bottom is no less than 2, no more than 8.
Wherein, circular seal ring is provided between the bonnet and the connecting portion of valve element, plays close when closed check valve
Envelope is acted on, and is effectively prevented the water in pipeline from producing and is flow backwards phenomenon.
Wherein, the hollow sleeve internal thread and bolt external screw thread match, and by rotation and bolt, are capable of achieving valve element in sky
Sliding up and down in chamber, reaches purpose of the control valve port with flow section, so as to realize throttle grverning.
The beneficial effects of the utility model are as follows：
A kind of weaving machine with water spraying check valve of the present utility model, using spring pressurization, valve element props up valve when being allowed to usual
The bottom of lid.When the water pressure for having the discharge orifice for facing bonnet is produced, water pressure presses to valve by bonnet discharge orifice
Core, at this moment the spring of valve element bottom compressed, valve is got through, and check valve realizes one-way conduction；Valve element is acted on when having below
Hydraulic pressure when, valve element is pushed upwardly, and check valve enters cut-off state.The blind hole of connecting portion and small straight in the utility model structure
Footpath key gap uses cooperatively, it is ensured that can smoothly be moved up and down in the drive bottom spool of spring, be not in stuck
Phenomenon and prevent the spring not supported from causing valve element or so to offset, there is check valve and dam halfway problem；Meanwhile,
Bolt and hollow sleeve by Design of Screw Thread can adjusting spool up and down radial position, reach the mesh for controlling valve port with flow section
, so as to realize throttle grverning；Finally, when check valve use time too long after, spring failure can be by bolt support and regulation
Valve element is radially movable, effectively prevents valve element thrust not enough, the halfway problem of valve closing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that herein
Described specific embodiment be only used for explain this use it is new.
Weaving machine with water spraying of the present utility model is described in detail with check valve with reference to Fig. 1.
Weaving machine with water spraying check valve of the present utility model, the check valve includes the bonnet 1 with discharge orifice 10, valve body 3, bottom
Lid 4, valve element 5, spring 6 and bolt 9, are connected through a screw thread between the bonnet 1 and valve body 3, the valve body 3 and bottom 4 it
Between be connected by screw, the bonnet 1, valve body 3, bottom 4 form a cavity 8, the position of the bottom 4 including bottom interstitial hole
Putting in the hollow sleeve 41 and water hole 42 of the bearing of trend (vertical direction) to cavity, the hollow sleeve 41 has internal thread,
The bolt 9 includes the different key of two sections of diameters, and the major diameter key 91 below the bolt is carried and spiral shell in hollow sleeve
