Abstract
The invention discloses a stop valve, belongs to the technical field of stop valves, and aims to solve the technical problem of providing the stop valve with simple structure and low cost. The technical scheme is that: a valve body is a hollow column; the two ends of the valve body are provided with internal threads; a diaphragm is a bowl-shaped circular ring and is connected with the left end in the valve body through the threads; a valve core is pressed in a hole of the diaphragm through a spring; one end of the spring is pressed against the valve core, and the other end of the spring is pressed against a spring seat; the spring seat is a circular sheet with external threads; the circular sheet is uniformly provided with holes; the spring seat is connected with the right end in the valve body through the threads; a locking piece is a circular ring with external threads and is connected with the right side of the spring seat through the threads; the valve core is spherical or conical and is made of rubber, glass or metal; and the two ends of the valve body are provided with external threads. The stop valve can be applied to water, oil or gas conveying pipelines.
Description
Technical field
A kind of stop valve of the present invention belongs to the stop valve technical field.
Background technique
As everyone knows, when eminence was guided lower into, water was that nature flows with water; If but wanted to accelerate the flowing velocity of water, a water pump then need be connected, when not needing water to continue stream; Water pump quits work, but water also can continue toward dirty, at this moment just needs a valve stop flowing of water.Though more existing valve comparisons are accurate, complex structure, cost height also need manpower or electromagnetic force to start, and can not realize automation, can't satisfy customer requirements.
Summary of the invention
The present invention overcomes the deficiency of existing technology, and technical problem to be solved provides a kind of stop valve simple in structure, with low cost.
In order to solve the problems of the technologies described above, the technological scheme that the present invention adopted is: a kind of stop valve comprises: valve body, catch, spool, spring, spring seat and locking plate; Valve body is a hollow cylinder, and two ends of valve body all is processed with internal thread, and catch is the annulus of bowl-type; Catch is through being threaded in the left end of valve inner, and spool withstands on through spring in the hole of catch, and an end of spring withstands on the spool; The other end of spring withstands on the spring seat, and spring seat is uniformly distributed with porose for being with externally threaded disk on the disk; Spring seat is through being threaded in the right-hand member of valve inner; Locking plate is for being with externally threaded annulus, and locking plate is through being threaded in the right side of spring seat, and catch, spring seat and locking plate all can be regulated through screw thread in the position of valve inner.
Described spool or be spherical, or be taper.
The material of said spool or be rubber, or be glass, or be metal.
Described valve body two ends are processed with outside thread.
The beneficial effect that the present invention is compared with prior art had is:
1, the present invention is simple in structure, can make the product that caliber varies in size as required, and with low cost.
2, all be connected with valve body with spring seat owing to catch, so can adjust cracking pressure of the present invention through the distance between adjustment catch and the spring seat through screw thread.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further explanation:
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 is that valve body, 2 is that catch, 3 is that spool, 4 is that spring, 5 is that spring seat, 6 is locking plate.
Embodiment
As shown in Figure 1, a kind of stop valve of the present invention comprises: valve body 1, catch 2, spool 3, spring 4, spring seat 5 and locking plate 6; Valve body 1 is a hollow cylinder, and the two ends of valve body 1 all are processed with internal thread, and catch 2 is the annulus of bowl-type; Catch 2 is through being threaded in the left end of valve body 1 inside, and spool 3 withstands on through spring 4 in the hole of catch 2, and an end of spring 4 withstands on the spool 3; The other end of spring 4 withstands on the spring seat 5, and spring seat 5 is uniformly distributed with porose for being with externally threaded disk on the disk; Spring seat 5 is through being threaded in the right-hand member of valve body 1 inside, and locking plate 6 is for being with externally threaded annulus, and locking plate 6 is through being threaded in the right side of spring seat 5.
Described spool 3 or be spherical, or be taper.
The material of said spool 3 or be rubber, or be glass, or be metal.
Described valve body 1 two ends are processed with outside thread.
Described catch 2 is a bowl-type, when this stop valve is closed, can make through the face of its circular arc because of the impact spool 3 good returns of deviation to some extent; On described spool 3, can make a boss, boss inserts in the spring, can prevent spool 3 disengaging configurations; Described locking plate 6 can play the effect that prevents that spring seat 5 from becoming flexible.
Working procedure:
Water is being used the present invention when eminence is guided lower into, effect of the present invention is when pump working, to open, and makes water flows, when water pump stops, closing, and makes the water can be owing to deadweight continues to dirty.Before the use, according to actual needs earlier, through the distance between adjustment catch 2 and the spring seat 5; Adjust cracking pressure of the present invention, then the present invention is received in the water route, when the present invention inserts; Should note direction, it is water intake that an end of catch 2 is arranged, and the end that locking plate 6 is arranged is a water outlet.After the access, when the pressure of the water that transmits when water pump reached cracking pressure, this stop valve was opened; Water goes out water outlet through hole on the catch 2 and the orifice flow on the spring seat 5, flowing to desired location through other pipeline, when water pump quits work; Owing to there has not been the pressurization of water pump; The underpressure that water produces owing to conducting oneself with dignity is to open this stop valve, and this stop valve is closed, and water stops to flow.
The present invention is of many uses, can also apply in the oil circuit and air delivering pipeline that need open automatically, close, also can be applied in some water routes that need one-way flow, oil circuit and the air delivering pipeline.
