Abstract
The utility model relates to a stop valve. The stop valve comprises a valve body provided with a valve cavity, as well as a valve cover and a valve rod which are arranged on the valve body, wherein the valve body is provided with a flow-in channel for medium to flow into the valve cavity and a flow-out channel for the medium to flow out of the valve cavity; the lower end of the valve rod is fixedly provided with a valve clack for controlling the flow-in channel to be communicated with or cutoff from the valve cavity; the lower end of the valve rod is sheathed with a pressing sleeve; and the valve rod is fixedly connected with the pressing sleeve. The stop valve also comprises a slit sleeve for fixing the pressing sleeve, wherein the slit sleeve is fixedly connected with the valve clack through a screw. By adopting the technical scheme, the stop valve provided by the utility model can still work normally when bearing high pressure.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of stop valve.
Background technique
At present, existing a kind of stop valve includes the valve body that is provided with valve pocket, be arranged on the valve gap on the valve body, valve rod, valve body is provided with the flow channel that flows into valve pocket for medium, flow out the flow pass of valve pocket for medium, the valve rod lower end is installed with and is used to control flow channel and valve pocket conducting, the flap that ends, the valve rod lower end is arranged with gland, gland is provided with outside thread, the corresponding outside thread of flap position is provided with tapped hole, the valve rod lower end surface is extended with flange perpendicular to stem shaft to laterally, be provided with the cavity that is used for ccontaining flange in the flap and constitute fixedlying connected of valve rod and flap, the still stop valve of this structure, when the valve pocket internal pressure is big, gland is unreliable with being threaded of flap, can cause losing efficacy, and makes the stop valve cisco unity malfunction.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, it is a kind of when bearing high pressure that the utility model provides, stop valve that still can proper functioning.
The technical solution of the utility model: a kind of stop valve, include the valve body that is provided with valve pocket, be arranged on the valve gap on the valve body, valve rod, valve body be provided with for medium flow into valve pocket flow channel, flow out the flow pass of valve pocket for medium, the valve rod lower end is installed with the flap that is used to control flow channel and valve pocket conducting, ends, described valve rod lower end is arranged with gland, described valve rod is fixedlyed connected with gland, also includes the split collar that is used for fixing gland, and described split collar is connected through screw with flap.Adopt technique scheme, when high pressure, valve rod bears pressure and is unlikely in the past flap and is subjected to high pressure to make thread failure, and its structure is also simple, and is easy to process.
Further improvement of the utility model: described gland cross section profile is " protruding " font, is provided with the cavity that is complementary with described gland cross section profile in the described split collar, and described gland places and constitutes described split collar fixing gland in the described cavity.Adopt above-mentioned further improvement, simple to the fixed structure of gland, reliable.
Further improvement more of the present utility model: described gland is provided with a through hole, the corresponding described lead to the hole site of described flap is provided with groove, described through hole is communicated with the cavity volume of formation cross section for " protruding " font with groove, described valve rod lower end surface is extended with flange perpendicular to stem shaft to laterally, described flange is positioned at described cavity volume bottom and constitutes fixedlying connected of valve rod and gland.Adopt above-mentioned further improvement again, make things convenient for the installation of valve rod, dismounting, simple in structure, easy to process.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is an I part partial enlarged drawing among Fig. 1.
Embodiment
As shown in Figure 1, 2, a kind of stop valve, include the valve body 1 that is provided with valve pocket 11, be arranged on the valve gap 2 on the valve body 1, valve rod 3, valve body 1 is provided with the flow pass 13 that flows out valve pocket 11 for the flow channel 12 of medium inflow valve pocket 11, for medium, valve rod 3 lower ends are installed with the flap 4 that is used to control flow channel 12 and valve pocket 11 conductings, ends, described valve rod 3 lower ends are arranged with gland 5, described valve rod 3 is fixedlyed connected with gland 5, also include the split collar 6 that is used for fixing gland 5, described split collar 6 is fixedlyed connected through screw 7 with flap 4.In this specific embodiment, described valve pocket 11 is arranged on the top of described flow channel 12, and described valve gap 2 is fixedlyed connected with valve body 1 through bolt.
Described gland 5 cross section profiles are " protruding " font, are provided with the cavity 61 that is complementary with described gland 5 cross section profiles in the described split collar 6, and described gland 5 places and constitutes the fixing of 6 pairs of glands 5 of described split collar in the described cavity 61.Described be complementary for described cavity 61 cross sections also for " protruding " font, the depth of section that described gland 5 is positioned at big mouthful of place of " protruding " font is slightly less than the depth of section that described split collar 6 is positioned at big mouthful of place of " protruding " font, rise at valve rod 3 like this, when descending, could guarantee that valve rod 3 is with flap 4 motions.
In the utility model, described gland 5 is provided with a through hole 51, described flap 4 corresponding described through holes 51 positions are provided with groove 41, described through hole 51 is communicated with the cavity volume 8 of formation cross section for " protruding " font with groove 41, described valve rod 3 lower end surfaces axially are extended with flange 31 laterally perpendicular to valve rod 3, and described flange 31 is positioned at described cavity volume 8 bottoms and constitutes fixedlying connected of valve rod 3 and gland 5.Described flange 31 height vertically is slightly less than the depth of section that cavity volume 8 is positioned at big mouthful of place of " protruding " font, and in the time of could guaranteeing valve rod 3 risings, decline like this, gland 5 can move thereby drive flap 4 together with valve rod 3 motions.
