Abstract
The utility model belongs to the technical field of valves, in particular to a self-pressing stop valve. The self-pressing stop valve comprises a valve body, a valve clack, a valve cover and a piston, wherein the piston and an O-shaped sealing ring are arranged in the valve body; the valve body is partitioned into an upper cavity and a lower cavity by using the piston and the O-shaped sealing ring; the piston, a spring and the valve clack are arranged in the upper cavity; the spring is connected with the piston; the piston is further connected with a piston rod; the piston, the piston rod and the valve clack are connected integrally in a threaded manner in the upper cavity of the valve body; a metal winding gasket and a sealing ring are arranged in the lower cavity of the valve body. In the self-pressing stop valve, a brand new design thought is adopted, a hand wheel, a valve rod and a valve rod nut structure in the conventional stop valve are eliminated, self-sealing and opening of the stop valve are realized, and higher automation degree of the stop valve is realized. Moreover, the self-pressing stop valve is simple in structure, high in practicability, low in manufacturing cost, and suitable for being popularized and used in products of the same type.
Description
Technical field
The utility model belongs to valve technology field, specifically a kind of Self-pressuring stop valve.
Background technique
The open-shut device of stop valve (stop valve, Globe Valve) is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of valve seat.The forms of motion of valve rod, also has lifting rotation rod-type, and stop valve refers to the valve that closure member moves along valve seat center line.According to this mobile form of flap, the variation of valve seat port is and flap stroke relation in direct ratio.Due to the valve rod of such valve open or shutoff stroke relatively short, and there is cutting function very reliably, because the variation of valve seat port and the stroke of flap become just this routine relation, be very suitable for the adjusting to flow again.Therefore, such stop valve valve is suitable as cut-out or adjusting and throttling use.
But, stop valve of the prior art, operation is too complicated, can't realize self-sealing and unlatching, to work, makes troubles.Therefore, need technical progress, structural improvement, makes the automaticity of stop valve higher.
Model utility content
The purpose of this utility model is in order to solve deficiency of the prior art, and a kind of stop valve that can realize self-sealing and unlatching is provided.
The utility model comprises valve body, flap, valve gap, piston, wherein in valve body, be provided with piston and O-ring seals, described piston and O-ring seals are divided into epicoele, cavity of resorption by valve body, wherein epicoele is provided with piston, spring, flap, spring is connected with piston, piston is also connected with piston rod, and the piston in valve body epicoele, piston rod and flap adopt to be threaded and be integral, and the cavity of resorption of valve body is provided with spiral wound gasket, seal ring.
Preferably, valve body comprises valve body top and valve body lower portion, and described valve body epicoele is arranged in valve body top, and valve body cavity of resorption is arranged in valve body lower portion, and valve body top, valve body lower portion are respectively arranged with through hole.
Preferably, valve body top is also provided with valve gap, is provided with two screws on described valve gap, and two through holes are connected with card.
Preferably, valve body top and valve body lower portion are separately installed with ball valve, and the through hole that connecting tube arranges through valve body upper and lower part connects ball valve.
Preferably, spiral wound gasket is fixedly mounted on valve body cavity of resorption, and seal ring is arranged in spiral wound gasket.
The utility model adopts brand-new mentality of designing, has cancelled the structural design of handwheel, valve rod and the Stem Mut of traditional stop valve, has realized self-sealing and the unlatching of stop valve, and the automaticity of stop valve is higher.In addition, the utility model is simple in structure, practical, and fabricating cost is not high, and this product is adapted at promoting the use of in like product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, valve body; 2, flap; 3, valve gap; 4, epicoele; 5, cavity of resorption; 6, valve body top; 7, valve body lower portion; 8, seal ring.
Embodiment
For making the technical solution of the utility model and feature clearer, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.At this, following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in the figure, the utility model comprises valve body 1, flap 2, valve gap 3, piston, wherein in valve body 1, be provided with piston and O-ring seals, described piston and O-ring seals are divided into epicoele 4 by valve body 1, cavity of resorption 5, wherein epicoele 4 is provided with piston, spring, flap, spring is connected with piston, piston is also connected with piston rod, piston in valve body epicoele 4, piston rod and flap adopt to be threaded and are integral, valve body cavity of resorption 5 is provided with spiral wound gasket, seal ring 8, wherein spiral wound gasket is fixedly mounted on valve body cavity of resorption 5, seal ring 8 is arranged in spiral wound gasket.
Valve body of the present utility model top 6 is also provided with valve gap 3, is provided with two screws on described valve gap 3, and two through holes are connected with card, and card plays the effect of spacing ball valve.
Concrete, when the position of two ball valves is communicated with valve body epicoele 4 on valve body top 6 and when valve body lower portion 7 is closed with valve body cavity of resorption 5, the thrust that epicoele 4 pressure mediums produce passes to flap by piston, piston rod, makes flap and valve body sealing surface close contact, and valve is in closing sealing state.
When the position of two ball valves is communicated with valve body cavity of resorption 5 in valve body lower portion 7 and when valve body top 6 closes with valve body epicoele 4, valve body epicoele 4 is without pressure, and valve promotes piston, piston rod and flap, now valve opening by self pressure.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give all mode of executions exhaustive.Every still row in protection domain of the present utility model of apparent variation that the technical solution of the utility model extends out or change that belong to.
