Abstract
The utility model discloses a kind of force switch one-way valve, it comprises valve body, valve rod and valve gap, and described valve body is provided with an import and an outlet; Described valve gap is detachably arranged on valve body; Described valve gap inside is provided with pilot seal; Described valve rod is arranged in pilot seal, and lower end extends to body cavity, and upper end extends to outside valve body, and the lower end of described valve rod is connected with sealing cone, and initial position is pre-tensioner to valve body import by Compress Spring, is in normally off.This one-way valve structures is simple, and fully-machinery type controls, and the high and good airproof performance of working stability, solves the defects such as the winding of fibrous foreign material, large particle card valve, can be used for the high concentration containing various impurity, the transfer pump valve of large particle degree slurries or pipeline valve.
Description
Technical field
The utility model relates to a kind of one-way valve, particularly relates to a kind of force switch one-way valve, belongs to pump valve technical field in mechanical technique.
Background technique
Force switch one-way valve mainly can replace transfer pump hose valves group, for conveyer for emptying warehouse transfer pump.Transfer pump hose valves group mainly contains following shortcoming: 1, bulky, causes space waste; 2, adopt hydraulic driving, cause energy waste; 3, cost of production is high.
Summary of the invention
For the deficiency of above technology, the utility model provides a kind of force switch one-way valve, is applicable to the mixed material of various concentration, granularity, and fully-machinery type controls, and without the need to additional energy source, structure is simple, cheap.
The utility model realizes with following technological scheme: a kind of force switch one-way valve, is characterized in that: it comprises valve body, valve rod and valve gap, and described valve body is provided with an import and an outlet; Described valve gap is detachably arranged on valve body; Described valve gap inside is provided with pilot seal; Described valve rod is arranged in pilot seal, and lower end extends to body cavity, and upper end extends to outside valve body, and the lower end of described valve rod is connected with sealing cone, and initial position is pre-tensioner to valve body import by Compress Spring, is in normally off.
Described Compress Spring one end is arranged on spring seat cylinder, the other end linking springs pressure cylinder; Described spring seat jacket casing is on valve rod; Described spring pressure cylinder is arranged on valve gap.
Described import is provided with stuffing box gland.
Owing to have employed technique scheme, the beneficial effects of the utility model are materials that described force switch one-way valve can be applicable to various concentration, granularity, and fully-machinery type controls, and without the need to additional energy source, structure is simple, cheap.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, valve body, 2, stuffing box gland, 3, sealing cone, 4, valve gap, 5, spring seat cylinder, 6, spring pressure cylinder, 7, valve rod, 8, Compress Spring, 9, pilot seal, 10, outlet, 11, import.
Embodiment
A kind of force switch one-way valve as described in Figure 1, is characterized in that: it comprises valve body 1, valve rod 7 and valve gap 4, and described valve body 1 is provided with an import 11 and an outlet 10; Described valve gap 4 is detachably arranged on valve body 1; Described valve gap 4 inside is provided with pilot seal 9; Described valve rod 7 is arranged in pilot seal 9, and lower end extends to valve body 1 inner chamber, and upper end extends to outside valve body 1, and the lower end of described valve rod 7 is connected with sealing cone 3, and initial position is pre-tensioner to valve body import 11 by Compress Spring 8, is in normally off.
Described Compress Spring 8 one end is arranged on spring seat cylinder 5, the other end linking springs pressure cylinder 6; Described spring seat cylinder 5 is enclosed within valve rod 7; Described spring pressure cylinder 6 is arranged on valve gap 4.
Described import 11 is provided with stuffing box gland 2.
This one-way valve is installed in pipeline, relies on mechanical external force F to change the lifting position of valve rod 7, thus the blocking-up of control media with pass through.Under nature, valve rod 7 is pre-tensioner to valve body import 11 by Compress Spring 8, and sealing cone 3 seals with stuffing box gland 2 and contacts, and blocks medium and passes through.When the effect that valve rod 7 is subject to external force F is lifted, medium flows into from valve body import 11, flows out from valve outlet 10.
