Abstract
The utility model discloses a kind of top-opening type stop valve, comprise valve body, valve body is provided with oil inlet passage and oil discharge passage, described oil inlet passage and oil discharge passage are communicated by the through hole on valve body seat surface, form sealing configuration by spring and steel ball on the left of through hole, be provided with the operating structure of push rod, plunger and swing arm composition on the right side of through hole, push rod withstands on steel ball through through hole, plunger tail is provided with the first screw thread, closely cooperates with the second screw thread in valve body.Top-opening type stop valve of the present utility model, can avoid exerting oneself during manual operation the excessive damage causing valve, valve body mesopore and seat surface are without coaxality requirement.
Description
Technical field
The utility model relates to stop valve field, specifically a kind of top-opening type stop valve.
Background technique
When spinning stop valve uses in hyperbaric environment, easily occur that valve body is revealed, the problems such as sealing is poor, valve block facial disfigurement, the distortion of the valve rod conical surface, this kind of valve also has two kinds of defects, one is the size that workman is difficult to grasp rotating force, and can not produce enough resiliently deformables when power is too little, sealing reliability is poor, power makes metal produce plastic deformation time too large, damage sealed seat surface.Two be valve body mesopore and seat surface alignment require very high, add the difficulty of manufacture.
Model utility content
In order to solve the above-mentioned technical problem existed in prior art, the utility model provides a kind of top-opening type stop valve, comprise valve body, valve body is provided with oil inlet passage and oil discharge passage, described oil inlet passage and oil discharge passage are communicated by the through hole on valve body seat surface, sealing configuration is formed by spring and steel ball on the left of through hole, the operating structure of push rod, plunger and swing arm composition is provided with on the right side of through hole, push rod withstands on steel ball through through hole, plunger tail is provided with the first screw thread, closely cooperates with the second screw thread in valve body.
Top-opening type stop valve of the present utility model, can avoid exerting oneself during manual operation the excessive damage causing valve, valve body mesopore and seat surface are without coaxality requirement.
Accompanying drawing explanation
Fig. 1 is the sectional view of top-opening type stop valve of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, top-opening type stop valve of the present utility model, comprise valve body 1, valve body 1 is provided with oil inlet passage 2 and oil discharge passage 3, and oil inlet passage 2 and oil discharge passage 3 are communicated by the through hole 4 on valve body seat surface, form sealing configuration on the left of through hole 4 by spring 5 and steel ball 6, the operating structure of push rod 7, plunger 8 and swing arm 9 composition is provided with on the right side of through hole 4, push rod 7 withstands on steel ball 6 through through hole 4, and plunger tail is provided with the first screw thread, closely cooperates with the second screw thread in valve body 1.
When top-opening type stop valve of the present utility model is closed, push rod 7 screws out, and steel ball 6 resets under the elastic force effect of spring 5, and during hydraulic work system, hydraulic oil acts on steel ball 6, and steel ball 6 is stressed pushes down valve body seat surface, and valve body seat surface deforms, steel ball 6 reliable sealing; When opening, push rod backs down steel ball 6, and hydraulic oil flows through along between steel ball 6 and seat surface.
