Abstract
The utility model discloses a high-pressure water valve for a gas water heater, which comprises a valve body, wherein a valve rod control passage and a water pressure limiting cavity, a water guide passage communicated the valve rod control passage with the water pressure limiting cavity is arranged between the valve rod control passage and the bottom surface of the water pressure limiting cavity; the central line 21 of the valve rod control passage is vertical to the central line of the water pressure limiting cavity; the horizontal distance between the central line of the valve rod control passage and the end surface of an opening of the water pressure cavity between 7 mm and 27 mm; thus, the materials are saved, and the cost is reduced; moreover, the utility model has the advantage of accurate pressure control.
Description
Technical field
The utility model relates to a kind of gas heater high pressure water valve.
Background technology
At present, generally use gas heater in the city dweller resident family, being arranged in the gas heater of its water valve is most important, and the present general on the market used water valve of gas heater, comprise valve body in its structure, described valve body is provided with valve rod control channel and system hydraulic pressure chamber, and valve rod control channel communicates with the control of system hydraulic pressure, and the horizontal range that the system hydraulic pressure chamber open end of this valve body arrives described valve rod control channel center line generally all at 28mm between the 35mm.
Thereby, 1), the center line horizontal range of system hydraulic pressure chamber open end and valve rod control channel is long the gas heater of said structure has the following disadvantages with water valve:, can be directed at the valve body internal pressure increases, and its water resistance is bigger, causes that pressure control is inaccurate, the unlatching of valve body or to close silk ribbon attached to an official seal or a medal slow; 2), system hydraulic pressure chamber and intake tunnel central axis distance, the volume of valve body is understood corresponding increase, causes its employed raw material many, thereby has increased the cost of product, is not suitable for the demand in market.
The utility model content
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of saving material, low, the accurate combustion gas thermal high of the pressure control hydrophone water valve of cost.
The technical solution of the utility model is: gas heater high pressure water valve, comprise valve body, described valve body is provided with valve rod control channel and system hydraulic pressure chamber, between the bottom surface in described valve rod control channel and system hydraulic pressure chamber conduit pipe being set is connected, the center line of valve rod control channel is perpendicular to the central axis in system hydraulic pressure chamber, and the horizontal range of the open end in the center line of described valve rod control channel and system hydraulic pressure chamber is between 7mm to 27mm.
Also be provided with through hole on the described 7 system hydraulic pressure chambeies, the through hole upper sleeve has safety valve, and the bottom surface in described system hydraulic pressure chamber is provided with the recess that joins with through hole.
Described safety valve is to be screwed onto on the through hole.
Concave depth on the bottom surface, described system hydraulic pressure chamber is between 1mm to 9mm.
Described conduit pipe and valve rod control channel are perpendicular.Horizontal range between the bottom surface in the center line of described valve rod control channel and system hydraulic pressure chamber is between the 7mm to 20mm.The horizontal length of described conduit pipe is between the 1mm to 16mm.
The beneficial effects of the utility model are:
1), since the open end in system hydraulic pressure chamber to described valve rod control channel central axis distance generally all at 35mm between the 28mm, and the horizontal range of the open end in the center line of described valve rod control channel of the present utility model and system hydraulic pressure chamber is between the 7mm to 27mm, thereby shortened the horizontal range of system hydraulic pressure chamber and valve rod control channel, improved its pressure control precision and operating efficiency thereof;
2), since the volume of valve body reduce to some extent, thereby the use of having saved raw material reduces the manufacturing cost of product, helps it and promotes the use of;
3), corresponding safety valve position is provided with a recess on the bottom surface in system hydraulic pressure chamber, recess has certain depth, and cooperates with the system hydraulic pressure chamber degree of depth, when making the pressure of pressing in the chamber more than or equal to 7 kilograms, and the effect of realization pressure release, safety;
