Abstract
The utility model relates to an anti-leakage natural gas valve, which is mainly technically characterized in that a pipeline valve comprises an operating handle, bolts, a fixing part, sealing parts, an inlet shell, an outlet shell, a spherical valve core, a groove, a valve rod and a warning device. The inlet shell and the outlet shell are fixed together through a second bolt, the fixing part and the inlet shell are fixed together through a first bolt, the fixing part is used for fixing a valve body on the inlet shell, and a gas passage is arranged between the inlet shell and the outlet shell. The sealing part is respectively arranged between the shell and the valve core and between the shell and the valve rod to further prevent leakage, and the anti-leakage natural gas valve has the advantages of long service life and the like and is widely applicable for natural gas pipelines.
Description
Technical field
The utility model relates to a kind of control valve unit, particularly relates to a kind of rock gas valve of anti-leak.
Background technique
At present, the valve of natural gas line setting be mostly be made of metal comprise assemblies such as following housing, valve rod, handle, spool and valve seat, between spool and housing, be provided with seal ring, realize the leakage between the path by the sealing circle, this valving in use is prone to following defective: because the frequent movement of the relative valve seat of spool, use of a specified duration and be prone to the leakage rock gas, can cause waste, may cause danger to a certain degree, and take place to be difficult for discovering under the leakage situation.
Summary of the invention
The purpose of this utility model is to provide a kind of difficult leakage and the rock gas valve that leakage situation can be discovered rapidly takes place.
The purpose of this utility model is by providing a kind of valve with following structure to realize, a kind of rock gas valve of anti-leak, it comprises operating lever, first bolt, fixed block, first Sealing, suction casing, second Sealing, outlet housing, spherical valve core, second bolt, groove, valve rod, warning device; Described suction casing and outlet housing are by described second bolt together, described fixed block and described suction casing are by first bolt together, be used for fixing valve body on described suction casing, between described suction casing and outlet housing, be provided with gas channel, described operating lever is installed in an end of described valve rod, described spool is a ball shape, be provided with through hole in the middle of it, and the top is provided with groove, the other end of described valve rod is installed in the groove, described outlet housing is provided with warning device, be used under leakage situation, giving the alarm, between housing and described spool, first Sealing is set, second Sealing is set between housing and valve rod.
Rock gas valve of the present utility model has double seal, has anti-leak energy supply preferably, and can give the alarm under leak case, can in time keep in repair or change the valve of revealing, and has further saved cost, has stopped dangerous generation.
Description of drawings
Fig. 1 is the rock gas valve of anti-leak of the present utility model.
Embodiment
Following thread is closed accompanying drawing the utility model is further described, as shown in the figure, suction casing 5 and outlet housing 7, fixed block 3 and suction casing 5 are fixed together by first bolt 2 and second bolt 9 respectively, in the middle of suction casing 5 and outlet housing 7, be provided with natural gas line, operating lever 1 is installed in an end of valve rod 11, the other end of valve rod 11 cooperates with the groove 10 that spherical valve core 8 tops are provided with, preferably connect by key, be provided with through hole in the middle of the spool 8, this through hole communicates with natural gas line, and spool top central authorities are provided with groove 10, and outlet housing 7 is provided with warning device 12, and this warning device 12 is made up of sensor and voice guard or tutorial light alarm, first Sealing 4 is set between housing and spool 8, second Sealing 6 is set between housing and valve rod 11.
During operation, when opening the rock gas passage, manual rotary manipulation handle 1, it is rotated, perhaps adopt motor to rotate this operating lever 1 automatically, owing to operating lever 1 is fixedlyed connected with valve rod 11, therefore, the valve rod 11 that makes operating lever 1 be connected also rotates, and the other end of valve rod 2 is inserted in the groove 10 of spool 8 top central authorities, connects by key, when valve rod 11 rotations, ball shape spool 4 is all opened up to passage also along with rotation.When closing the rock gas passage, counterrotating operating lever 1, make it drive valve rod 11 rotations, thereby spool 8 rotates to the position perpendicular with gas channel, blocking channel, and be used for further sealing the rock gas passage first Sealing 4 being set between housing and the spool 8 and second Sealing 6 is set between housing and valve rod 11, be used to prevent that rock gas from revealing.At this moment, warning device 12 starts, when the sensor in the warning device 12 takes place to leak to the rock gas passage, voice guard in the warning device 10 gives the alarm, perhaps caution light takes place in the tutorial light alarm, and notifying operation the person leak, and should in time overhaul or change.
In the utility model, adopted two Sealings, realized double seal, further improve the anti-leak function, and be provided with warning device, make and when taking place to leak, can in time report to the police.
