Abstract
The utility model belongs to valve field, that the device of monitoring valve leak and a kind of valve of monitoring valve stem seal of providing are not set for existing valve, comprise valve body, valve rod, spool, valve gap, actuator, valve pocket is provided with in valve body, filling body is provided with between valve rod and valve gap, the valve gap of the upper end of filling body is being provided with the monitoring device of sealing between a monitoring valve rod and valve gap, monitoring device comprises the water tank be arranged on valve gap, be marked with liquid in water tank, the surface of liquid will exceed the upper end portion of filling body.The utility model arranges the monitoring device of sealing between monitoring valve rod and valve gap on the valve gap of filling body upper end, when having leakage between valve rod and valve gap, gas can present bubble in water tank, easily like this to be found, thus keep in repair early, avoid the state of affairs to expand the potential safety hazard brought, thus guarantee the Security of air delivering pipeline.
Description
Technical field
The utility model belongs to valve technology field, particularly a kind of valve of monitoring valve stem seal.
Background technique
Now generally all sealed by stuffing box packing between valvular valve rod and valve gap, stuffing box packing sealing also there will be leakage phenomenon for a long time, when on the pipeline being used in the inflammable gas such as coal gas or rock gas or toxic gas time, the sealing of valve directly determines the safety of pipeline, if when there is slight leakage in valve, generally be difficult to perceive, will potential safety hazard be brought for a long time.
Model utility content
The purpose of this utility model does not arrange the device of monitoring valve leak and a kind of valve of monitoring valve stem seal of providing for existing valve.
The utility model is achieved by the following technical solution:
A kind of valve of monitoring valve stem seal, comprise valve body, valve rod, spool, valve gap, actuator, valve pocket is provided with in valve body, filling body is provided with between valve rod and valve gap, the valve gap of the upper end of filling body is being provided with the monitoring device of sealing between a monitoring valve rod and valve gap, monitoring device comprises the water tank be arranged on valve gap, is marked with liquid in water tank, and the surface of liquid will exceed the upper end portion of filling body.
Described water tank is provided with water filling hole.
A water outlet be communicated with valve pocket is provided with in the lower end of valve body.
Water filling hole and water outlet are equipped with valve.
The beneficial effects of the utility model: the utility model arranges the monitoring device of sealing between monitoring valve rod and valve gap on the valve gap of filling body upper end, when having leakage between valve rod and valve gap, gas can present bubble in water tank, easily like this to be found, thus keep in repair early, avoid the state of affairs to expand the potential safety hazard brought, thus guarantee the Security of air delivering pipeline.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
A kind of valve of monitoring valve stem seal as shown in Figure 1, comprise valve body 1, valve rod 2, spool 3, valve gap 4, actuator 5, valve pocket is provided with in valve body 1, filling body 6 is provided with between valve rod 2 and valve gap 4, the valve gap 4 of the upper end at filling body 6 is provided with the monitoring device of sealing between a monitoring valve rod 2 and valve gap 4, monitoring device comprises the water tank 7 be arranged on valve gap 4, is marked with liquid in water tank 7, and the surface of liquid will exceed the upper end portion of filling body 6.Described water tank 7 is provided with water filling hole 8.A water outlet be communicated with valve pocket 9 is provided with in the lower end of valve body 1.Water filling hole 8 and water outlet 9 are equipped with valve.When leaking between valve rod and valve gap, the water in water tank enters valve pocket, and the effect of water outlet is exactly get rid of the water in valve pocket.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection domain of the present utility model.
