Annular side.
Further, the left end cap annular side upper end and lower end are machined with communication port one.
Further, the valve seat annular side upper end and lower end offer communication port two.
Further, the arc spool annular side left end is fixed with boss, and the arc-shaped structure of boss left end, described
Sealing cone right side fits with boss left side, and the spring left end is connected to boss right side.
Further, the piston annular side is equipped with O-ring seal.
Further, the arc-shaped structure of piston right end.
The beneficial effects of the utility model:The hydraulic valve core of a kind of reduction pressure loss of the utility model, because of this practicality
It is novel to be added to screw plug, sealing ring, support ring, piston, left end cap, baffle ring, sealing cone, valve seat, arc spool, spring
And right end cap, the design improve the patency of fluid flowing, reduce the pressure loss, solve hydraulic valve in the prior art
The problem of pressure loss is serious in use.
Because the utility model is added to communication port one, which is convenient for the entrance of fluid, because the utility model is added to stream
Port two, which is convenient for the discharge of fluid, and because the utility model is added to O-ring seal, which improves piston and a left side
Leakproofness between end cap, because the utility model is added to boss, which improves what arc spool was contacted with sealing cone
Stability, the utility model is rational in infrastructure, realizes the purpose for reducing the pressure loss, good operation stability, reliability height.

Specific embodiment
To be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, below
With reference to specific embodiment, the utility model is expanded on further.
Referring to Fig. 1, the utility model provides a kind of technical solution:A kind of hydraulic valve core for reducing the pressure loss, including
Screw plug 1, sealing ring 2, support ring 3, piston 4, left end cap 5, baffle ring 6, sealing cone 7, valve seat 8, arc spool 9, spring
10 and right end cap 11, screw plug 1 be assemblied in 5 left end of left end cap, sealing ring 2 is assemblied in inside annular groove, and support ring 3 is installed
Inside the annular groove on 2 right side of sealing ring, annular groove is opened in 5 annular side left part position of left end cap, and piston 4 is assemblied in left end
Inside lid 5, baffle ring 6 is mounted on 5 right side of left end cap inside valve seat 8, and sealing cone 7 is arranged on 6 right side of baffle ring, valve seat 8
5 right end of left end cap is assemblied in, right end cap 11 is mounted on 8 right end of valve seat, and arc spool 9 is mounted in valve seat 8 and right end cap 11
Portion, 9 left end of arc spool are connected with piston 4, and spring 10 is assemblied in 9 annular side of arc spool, which improves fluid
The patency of flowing, reduces the pressure loss, and solving hydraulic valve in the prior art, the pressure loss is serious in use
Problem.
5 annular side upper end of left end cap and lower end are machined with communication port one, 8 annular side upper end of valve seat and lower end
Communication port two is offered, 9 annular side left end of arc spool is fixed with boss, and the arc-shaped structure of boss left end, sealed taper
7 right side of face fits with boss left side, and 10 left end of spring is connected to boss right side, and 4 annular side of piston is equipped with O-shaped
Sealing ring 2, the arc-shaped structure of 4 right end of piston.
Specific embodiment:During use, fluid is flowed by communication port one inside left end cap 5, so as to which fluid is to arc
Shape spool 9 generates thrust, and arc spool 9 is made to move right, and the movement band piston 4 of arc spool 9 moves right inside left end cap 5
It is dynamic, while 9 compressed spring 10 of arc spool, shrink spring 10, when arc spool 9 is detached with sealing cone 7, fluid passes through
Gap between arc spool 9 and sealing cone 7 is flowed into inside valve seat 8, when arc spool 9 drives boss to be moved to communication port two
During right side, fluid is flowed out by communication port two, and when piston 4 is moved to one position of communication port, piston 4 blocks communication port one,
Reduce so as to act on the pressure of 9 left end of arc spool, to moving to left under the elastic force effect that arc spool 9 restores deformation in spring 10
Dynamic, the pressure loss is small in fluid flow process.
