Abstract

A vertical automatic air-discharging valve of the utility model is composed of a valve body, a valve cover, and a sealing ring of the valve body. The utility model is characterized in that a guide bushing integrated with the valve cover and equipped at the inner side of the valve cover is corresponding with one end of a valve rod with blocker, the lower end of the valve rod is connected with a floater, and a guide post positioned in the chamber of the valve body is parallel with the valve rod and limits the floater. The utility model makes use of a valve body chamber guide post to make the floater only up-and-down vertically move along the valve body chamber guide post, and air can be stocked in a floater chamber by drilling a plurality of bores with the diameter of 3 millimeters at the bottom of the floater, so that water can not log into the floater chamber, and the difficult problem of creeping in the floater chamber can be fundamentally solved.

Description

Vertical automatic exhaust valve

The utility model belongs to valve class technical field, specifically a kind of automatic control pressure vent that is used for gas in hot water heating or the water-supply line fluid removal system.

At present, the vertical automatic exhaust valve kind of gas has severally in hot water heating or the water-supply line fluid removal system, and wherein most widely used is the P11T-0.4 vertical automatic exhaust valve, because these valve installation and maintenance are convenient, cheap.However, this outlet valve exist certain defective as: Flow area is little, only is 0.502MM ², long obstruction easily service time; Gas flow is low, and energy saving is poor; Because of float adopts blow molding process, the water capacity easily penetrates into the float inner chamber, and float is sunk, and loses the float effect, accounts for about 8% of sales volume; Also have guide holder in valve body inlet in addition, the diameter of import is diminished, hindered the flow of water, make the sensitivity of opening of valves or closing motion relatively poor.

The purpose of this utility model provides a kind of cancellation guide holder, strengthens float volume, improves gas flow to reach sensitive energy-efficient vertical automatic exhaust valve.

The purpose of this utility model is achieved in that it includes that a bottom brings that the valve body of gas port, valve gap, valve seals, exhaust are chewed into, valve rod, shutoff, float, it is characterized in that being provided with valve gap in the inboard of valve gap is the guide sleeve of one, this guide sleeve is corresponding with valve rod one end that has shutoff, the lower end of valve rod then is connected with a float, is provided with directional post with the parallel and spacing float of valve rod at the inner chamber of valve body.During use this outlet valve is installed in required vent systems and does not hold on the pipeline of extreme higher position, the gas that is produced in the system can be discharged by this automatic control pressure vent at any time.

The bottom that the utility model also is included in hollow float is drilled with the hole of 1-4 3 millimeter.

The utility model has been cancelled guide holder, utilizes the body cavity directional post to make that float can only be in the up and down vertical motion of body cavity directional post, and replaces guide holder, has therefore increased the diameter of import, has increased the flow of water, improves the operating sensitivity of this valve greatly.Bore several diameters in addition in float bottom in the hole of 3 millimeter, make the float inner chamber have air, so water can not ooze in the inner chamber of float, fundamentally solved the difficult problem of float inner chamber infiltration in the past.Characteristics such as that the utility model also has is simple and reasonable, the volume of float increases, air displacement is big, work sensitivity, energy saving, installation and maintenance convenience, applied range, originally novel can also be on pipeline direct replacing inner body.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model

By shown in Figure 1,1 among the figure for the valve body of bringing gas port into, 5 for valve gap, 11 for valve seals, be connected with an exhaust at the top of valve gap 5 and chew 8, exhaust is chewed and is connected with a shutoff 9, exhaust is chewed and is chewed rubber cushion 7 by exhaust 9 times and link to each other with valve gap 5 and locate; Being provided with valve gap in the inboard of valve gap 5 is the guide sleeve of one, this guide sleeve is chewed corresponding with exhaust, have seal rubber pad 6 on the top of valve pocket inner valve stem 3, it is corresponding that sealing rubber cushion 6 is chewed 8 the portion of chewing by guide sleeve and exhaust, the lower end of valve rod then is connected with float 2, also be provided with directional post 4 with valve rod 3 parallel and spacing floats at the inner chamber of valve body 1,10 among Fig. 1 is fastening screw trip bolt in addition.During use, this automatic control pressure vent is installed on the pipeline of the terminal extreme higher position of required vent systems, the gas that is produced in the system can be discharged by this automatic control pressure vent at any time, that is: when water enters valve body, float is held up, valve rod rises thereupon, the seal rubber pad 6 at valve rod top is chewed sealing with exhaust rapidly, and when being full of air in the valve body, float falls by deadweight, chew and open exhaust rapidly, chew exhaust outside system by exhaust.

Claims

1, a kind of vertical automatic exhaust valve, it includes that a bottom brings that the valve body of gas port, valve gap, valve seals, exhaust are chewed into, valve rod, shutoff, float, it is characterized in that being provided with valve gap in the inboard of valve gap is the guide sleeve of one, this guide sleeve is corresponding with valve rod one end that has shutoff, the lower end of valve rod then is connected with float, is provided with directional post with the parallel and spacing float of valve rod at the inner chamber of valve body.

2, automatic control pressure vent according to claim 1 is characterized in that being drilled with in the bottom of hollow float the hole of 1-4 3 millimeter.
