Description
Technical field
The present invention relates to a kind of valve that can be used in liquid or the gas pipeline.
Background technique
Existing valve, their spool all is limited by the influence of hydraulic pressure or air pressure, and water or atmospheric pressure are big more, and the water that its spool bore or the pressure of gas are also just big more, thus the resistance that makes spool open or close also can correspondingly increase.So the applied force amount also can be very big when opening or closing.This just causes the wearing and tearing aggravation of spool and causes leakage, and shorten working life.
Summary of the invention
At above-mentioned the problems of the prior art, the object of the present invention is to provide a kind of valve, it is not subjected to hydraulic pressure pressure influence, opens or closes freely, and spool can not wear and tear, long service life.
The technological scheme that the present invention is taked for its purpose of realization: a kind of valve, comprise valve body, valve rod, inlet opening and delivery outlet, described valve rod is a hollow article, cloth through hole on the valve rod, establish stuffing box gland between valve rod and the upper limit ring, along being fixed on the valve rod, the stuffing box gland outer is fixed on inwall on the valve body in the stuffing box gland, and the upper limit ring is connected to valve body top; Establish valve pocket between valve rod and the lower limit ring, along being fixed on the valve rod, the valve pocket outer is fixed on inwall under the valve body in the valve pocket, and the lower limit ring is connected to valve body lower portion; Forming cavity between stuffing box gland and the valve pocket is connected with described inlet opening.
Described through hole is established a row at least around valve rod, through hole be shaped as long strip, the through hole upper end is positioned at valve pocket along the top, the through hole lower end is positioned at valve pocket along the below; Described delivery outlet is arranged on the valve body below.
Described through hole can set up two rows separately around valve rod, and last exhausting hole is positioned at valve pocket along the top, and following exhausting hole is positioned at valve pocket along the below; Described delivery outlet is arranged on the valve body below.
A stuffing box gland also can be established in described valve pocket below, forms output cavity therebetween, this output cavity be arranged on valve body side delivery outlet and be connected.
Described valve rod, valve body and limited ring can adopt metal or plastic production, and described stuffing box gland and valve pocket can adopt elastic caoutchouc to make.
Valve of the present invention is no matter in off position down or under opening state, because effect, the cavity that forms between stuffing box gland and the valve pocket and the valve rod cavity internal and external pressure balance of through hole on the valve rod.Stuffing box gland and valve pocket belong to the rolling type motion together when motion, so frictional resistance is very little.When valve rod when the valve pocket direction is moved, stem through-hole is opened; When valve rod when the stuffing box gland direction moves, valve closing.
Beneficial effect of the present invention: be not subjected to hydraulic pressure pressure influence, open or close freely, spool can not wear and tear, long service life.
Description of drawings
The present invention is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the embodiment of the invention one a sectional structure schematic representation, and wherein Figure 1A is a valve opening state, and Figure 1B is the valve closing state;
Fig. 2 is the embodiment of the invention two sectional structure schematic representation, and wherein Fig. 2 A is a valve opening state, and Fig. 2 B is the valve closing state;
Fig. 3 is the embodiment of the invention three sectional structure schematic representation.
Among the figure 1, valve rod, 2, stuffing box gland, 3, through hole, 4, valve pocket, 5, the lower limit ring, 7, delivery outlet, 8, valve body, 9, the inlet opening, 10, the upper limit ring, 11, lower sleeve gasket.
Embodiment
Embodiment one
Referring to Fig. 1, comprise valve body 8, valve rod 1, inlet opening 9 and delivery outlet 7, valve rod 1 is a hollow article, cloth through hole 3 on the valve rod, establish stuffing box gland 2 between valve rod 1 and the upper limit ring 10, along being fixed on the valve rod 1, stuffing box gland 2 outers are fixed on inwall on the valve body 8 in the stuffing box gland 2, and upper limit ring 10 is connected to valve body 8 tops.Establish valve pocket 4 between valve rod 1 and the lower limit ring 5, along being fixed on the valve rod 1, valve pocket 4 outers are fixed on 8 times inwalls of valve body in the valve pocket 4, and lower limit ring 5 is connected to valve body 8 bottoms.Forming cavity between stuffing box gland 2 and the valve pocket 4 is connected with inlet opening 9.Valve rod 12, stuffing box gland 2 and valve pocket 4 constitute spool.
In this example, described through hole 3 is shaped as long strip, establishes a row around around the valve rod, and through hole 3 upper ends are positioned at valve pocket along the top, and the through hole lower end is positioned at valve pocket along the below; Delivery outlet 7 is positioned at the valve body below.
Press under the valve rod, valve opening, shown in Figure 1A, through hole 3 upper ends water inlets or air inlet, through hole 3 lower end water outlets or give vent to anger, delivery outlet 7 is the annular port between valve rod and the valve body.To draw on the valve rod, valve closing, the through hole bottom is the valve pocket sealing, shown in Figure 1B.
Embodiment two
This routine through hole 3 sets up two rows separately around valve rod 1, and last exhausting hole is positioned at valve pocket 4 along the top, and following exhausting hole is positioned at valve pocket 4 along the below, and all the other are all identical, referring to Fig. 2.
