Abstract

The utility model relates to a valve, in particular to a piston valve. The piston valve comprises a three-way valve, a piston cavity arranged in the three-way valve, a piston and baffle rings, wherein the piston cavity is formed in the middles of two water inlets of the three-way valve, and a water outlet hole is formed on the piston cavity and opposite to a water outlet; the piston is arranged in the piston cavity and moves left and right in the piston cavity under the pushing action of pressure at the water inlets; and the baffle rings are arranged at both ends of the piston cavity, the inner diameter of the baffle rings is slightly smaller than the outer diameter of the piston, and the baffle rings are used for preventing the piston from moving out of the piston cavity. The piston valve has the advantages of is energy conservation, safety, reliability, high switching speed and long service life; and elements can be meticulously selected fully according to the characteristics of the water differential pressure, thereby ensuring the product quality.

Description

Piston valve

Technical field

The utility model relates to valve, refers in particular to a kind of piston valve.

Background technique

At present, our used valve is the valve of manual tune mostly, lack always a kind of can be according to the self-regulating valve of intake pressure size.Particularly in the pipeline of solar gas water heater is installed, what adopt now all is manual valve, need manual operation to open the valve of solar energy or combustion gas end, can't accomplish safely, energy-conservation, and because frequent switch has also shortened working life of valve.

Summary of the invention

The purpose of this utility model is improved, is innovated at shortcoming that exists in the background technique and problem, provides a kind of energy self-regulating piston valve.

The technical solution of the utility model is that structure is a kind of by threeway be arranged on the valve that piston cavity, piston and baffle ring in the threeway are formed, wherein:

Piston cavity is arranged on the middle part of threeway two water intakes, and piston cavity is provided with osculum, and osculum is over against water outlet;

Piston is arranged in the piston cavity, and piston is by promotion move left and right in piston cavity of water intake pressure;

Baffle ring is arranged on the two ends of piston cavity, and the internal diameter of baffle ring is slightly less than the external diameter of piston, and baffle ring stops piston to shift out piston cavity.

Advantage of the present utility model and beneficial effect:

1, energy saving.In the use of solar gas water heater, when solar water heater water-temperature was lower than 50 ℃, solenoid valve was not worked during water, and electric energy has been saved in solenoid valve work during water, and hot water relies on gas water-heater, with how many heating what.

2, safe and reliable.Control voltage water, electricity separate, and human body is not damaged.

3, transfer speed is fast.Move by the piston in the water pressure pushing piston valve, close the solar water heater water route.

4, long service life.The utility model according to water-based pressure reduction characteristics, is selected components and parts fully meticulously, has guaranteed quality of product.

Embodiment

By Fig. 1 to 5 as can be known, the utility model is made up of threeway 1 and the piston cavity 2, piston 3 and the baffle ring 4 that are arranged in the threeway 1, wherein:

Piston cavity 2 is arranged on the middle part of 1 liang of water intake 6 of threeway, and piston cavity 2 is provided with osculum 9, and osculum 9 is over against water outlet 7;

Piston 3 is arranged in the piston cavity 2, and piston 3 is by promotion move left and right in piston cavity 3 of water intake 6 pressure;

Baffle ring 4 is arranged on the two ends of piston cavity 2, and the internal diameter of baffle ring 4 is slightly less than the external diameter of piston 3, and baffle ring 4 stops pistons 3 to shift out piston cavity 2.

Osculum 9 described in the utility model evenly is in staggered distribution at piston cavity 2 end faces middle parts over against water outlet 7 positions, and forms and enter piston cavity 2 from water intake 6, connects the flow channel of water outlets 7 again through osculum 9.Hoop has a seal ring 5 on the described piston 3.Described water intake 6 is connected annular knurl inipple 8 respectively with water outlet 7.

Working principle of the present utility model:

1, when the solar water actuator temperature is more than 50 ℃, no microcomputerized control voltage output, piston is moved to the left by solar water heater pressure, forms the solar water heater water-flowing path.

2, when the solar water actuator temperature is below 50 ℃, the output of microcomputerized control voltage: the one, when water was static, the current electric switch disconnected, and solenoid valve is not worked; The 2nd, when water flowed, the current electric switch was connected, solenoid valve work, and piston moves right rapidly by tap water pressure, forms the gas water-heater water-flowing path.

3, manual state: when solar water actuator temperature below 50 ℃, during microcomputerized control voltage no-output, can click the heat button on the micro computer observing and controlling instrument, make the output of microcomputerized control voltage.When water was static, the current electric switch disconnected, and solenoid valve is not worked; When water flowed, the current electric switch was connected, solenoid valve work, and piston moves right rapidly by tap water pressure, forms the gas water-heater water-flowing path.

Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; engineers and technicians make the technical solution of the utility model in related domain various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
