Abstract
The utility model provides a liquid tee bend valve that opens circuit returns, includes joint, case, spring, and it has the step working chamber to open in the joint, places case and spring in the working chamber, and the plug screw is twisted and is gone into to connect, and spring one end is supported on the case, the other end supports on the plug screw, connects and twists the convex valve body, and the case is with to connect the tapering sealed. Its simple structure, the cost of manufacture is low for colliery hydraulic support returns in the liquid pipeline.
Description
Technical field
The utility model relates to a kind of time liquid threeway cutout valve, and specifically a kind of coal mine hydraulic supporting uses back liquid threeway cutout valve.
Background technology
Chinese patent once disclosed a kind of monolithic and returned liquid threeway cutout valve (CN201220421400), comprise joint, spool, back-moving spring and valve body, the oil-in of spool and joint is tightly connected, the groove installing described joint is provided with at the external surface of described valve body, the inwall of groove is provided with the through hole being communicated with the oil-in of joint and the working chamber of valve body, back-moving spring one end is against on spool, and the other end is against on the inwall of groove, between joint with valve body and for being threaded.
Summary of the invention
The utility model object is that providing a kind of returns liquid threeway cutout valve, and its structure is simple, and cost of manufacture is low, in coal mine hydraulic supporting liquid back pipe road.
For achieving the above object, the solution that the utility model is taked is: a kind of time liquid threeway cutout valve, comprise joint, spool, spring, step working chamber is had in joint, place spool and spring in working chamber, plug screw is screwed into joint, and spring one end is against on spool, the other end is against on plug screw, joint is screwed into convex valve body, spool and joint taper sealing.
This kind returns liquid threeway cutout valve compared with existing like product, has following features: owing to adopting convex valve body, save joint and valve body connector, and structure is simple, and cost of manufacture is low, in coal mine hydraulic supporting liquid back pipe road.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment.
In figure: 1, joint, 2, spool, 3, spring, 4, plug screw, 5, O RunddichtringO, 6, convex valve body.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, description is remake to the utility model.
See Fig. 1, a kind of time liquid threeway cutout valve, comprise joint 1, spool 2, spring 3, step working chamber is had in joint 1, place spool 2 and spring 3 in working chamber, plug screw 4 is screwed into joint 1, and spring 3 one end is against on spool 2, the other end is against on plug screw 4, joint 1 is screwed into convex valve body 6, spool 2 and joint 1 taper sealing.
See Fig. 1, described joint 1 outer wall embeds O RunddichtringO 5.The specification of O RunddichtringO 5 is 38mm × 3.1mm.
See Fig. 1, this kind returns its rated operating pressure of liquid threeway cutout valve: 20MPa, metered flow: 250-320L/min.When height pushes back liquid by joint 1, overcome the elastic force of spring 3, spool 2 displacement, in high pressure back fluid spool 2, passage enters working chamber, through plug screw 4 mesopore, from two ports of convex valve body 6 out.
Claims (2)
1. one kind is returned liquid threeway cutout valve, comprise joint (1), spool (2), spring (3), it is characterized in that: joint has step working chamber in (1), spool (2) and spring (3) is placed in working chamber, plug screw (4) is screwed into joint (1), spring (3) one end is against on spool (2), the other end is against on plug screw (4), joint (1) is screwed into convex valve body (6), spool (2) and joint (1) taper sealing.
