Description
Technical field
The utility model belongs to mechanical control technique field, particularly a kind of parallel type double-flashboard prop open type gate valve spool.
Background technique
At present, existing valve core for gate valve, valve seat is to be directly welded on valve body, grinding size is undesirable, unreasonable structure, and the parts that strut are made up of flashboard frame, wedge-shaped blocks and three parts of spring, complex structure, and course of working is loaded down with trivial details, time-consuming taking a lot of work, cost is high; Valve body and guide rail adopt integrally casting, and processing guide rail needs special equipment, and cost is high.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of parallel type double-flashboard prop open type gate valve spool.
To achieve these goals, the utility model comprises valve body, valve seat insert, valve seat, left and right flashboard, flashboard frame, valve rod and guide rail; Wherein valve seat is arranged on valve body, between valve seat and valve body, is provided with valve seat insert, and left and right flashboard is arranged on valve seat, and flashboard frame connects left and right flashboard, and valve rod is arranged on flashboard frame, and guide rail is connected on valve body.
Described inner side, valve seat end arranges an annular groove, and valve seat insert is embedded in annular groove, and valve seat is threaded connection mode and is tightened on valve body, and valve seat inner side arranges four rectangular recess;
Described flashboard frame adopts T-shaped groove to be connected with valve rod;
Described guide rail adopts welding manner to be connected with valve body.
Working principle of the present utility model: 1. valve opening: when valve rod upwards rises under the drive of drive unit, valve rod drives flashboard frame jointly to rise, simultaneously, the left and right boss of flashboard frame drives left and right flashboard together to rise, and flashboard and valve seat depart from and then make spool under valve rod drives, complete the opening process of valve.Because flashboard frame is double inclined plane, throw off on inclined-plane at the moment of just having risen and left and right flashboard, depends on the idle stroke of flashboard frame and left and right flashboard 3mm, due to left and right flashboard and the disengaging of flashboard frame, make left and right flashboard not be subject to External Force Acting, now between flashboard sealing surface also without friction;
2. valve closing: valve rod utilizes the left and right boss of flashboard frame to drive left and right flashboard to do together descending motion in moving downward under the drive of drive unit, now below the flashboard of left and right, fit with the left and right boss of flashboard frame, left and right flashboard is fixed along with the motion of flashboard frame; In the time that flashboard frame continues to decline, the inclined-plane of the double inclined plane of flashboard frame and left and right flashboard fits tightly completely, utilizes the power of diagonal brace that left and right flashboard is strutted, and forces between left and right flashboard and sealing surface of seat and fits tightly, and spool completes and closes under the drive of valve rod.
The beneficial effects of the utility model: 1. the utility model valve seat and valve body are for being threaded; Good for reaching the sealing effect of valve seat and valve body, between valve seat and valve body, be provided with a seal ring; Owing to adopting Split type structure, valve seat can be ground to separately final ideal dimensions, and structure is more reasonable, has shortened milling time, has reduced man-hour, and then has reduced cost of production;
2. the parts that strut are only used part of flashboard frame, are provided with double inclined plane and replace wedge-shaped blocks and spring, can meet function needs, save raw material, can simplify again process step, reduce production costs thereby save time;
3. valve body and guide rail are to adopt Split type structure, and guide rail can be processed separately, is welded on valve body after processing again, does not need special device, and easy casting process, saves time, and have improved again the technology capability of processing.

Embodiment
Detailed structure of the present utility model describes in conjunction with specific embodiments.
As shown in Figure 1, comprise valve body 1, valve seat insert 2, valve seat 3, left and right flashboard 4, flashboard frame 5, valve rod 6 and guide rail 7; Wherein valve seat 3 is arranged on valve body 1, between valve seat 3 and valve body 1, is provided with valve seat insert 2, and left and right flashboard 4 is arranged on valve seat 3, and flashboard frame 5 connects left and right flashboard 4, and valve rod 6 is arranged on flashboard frame 5, and guide rail 7 is connected on valve body 1.
As shown in Figures 2 and 3, described valve seat 3 inner sides, end arrange an annular groove, and valve seat insert 2 is embedded in annular groove, and valve seat 3 is threaded connection mode and is tightened on valve body 1, and valve seat 3 inner sides arrange four rectangular recess;
As shown in Figure 4, described flashboard frame 5 adopts T-shaped groove to be connected with valve rod 6;
Described guide rail 7 adopts welding manner to be connected with valve body 1.
Working principle of the present utility model: 1. valve opening: when valve rod 6 upwards rises under the drive of drive unit, valve rod 6 drives flashboard frame 5 jointly to rise, simultaneously, the left and right boss of flashboard frame 5 drives left and right flashboard 4 together to rise, and left and right flashboard 4 departs from valve seat 3 and then makes spool under valve rod 6 drives, complete the opening process of valve.Because flashboard frame 5 is double inclined plane, inclined-plane disengagement in the moment of just having risen with left and right flashboard 4, depends on the idle stroke of flashboard frame 5 and left and right flashboard 3mm, because left and right flashboard 4 and flashboard frame 5 depart from, make left and right flashboard 4 not be subject to External Force Acting, now between sealing surface of valve plate 2 also without friction;
2. valve closing: valve rod 6 utilizes the left and right boss of flashboard frame 5 to drive left and right flashboard 4 to do together descending motion in moving downward under the drive of drive unit, now below left and right flashboard 4, fit with the left and right boss of flashboard frame 5, left and right flashboard 4 is fixed along with flashboard frame 5 moves; In the time that flashboard frame 5 continues to decline, the inclined-plane of the double inclined plane of flashboard frame 5 and left and right flashboard 4 fits tightly completely, utilize the power of diagonal brace that left and right flashboard 4 is strutted, force between left and right flashboard 4 and sealing surface of seat 2 and fit tightly, spool completes and closes under the drive of valve rod 6.
