Abstract
The invention discloses a pressure balance valve used for a split-typed solar water heating system, comprising a valve body (1) and a pressure releasing spring (2); one end of the valve body (1) is provided with a through pipeline (3) and the other end thereof is provided with a pressure releasing top rod (4) and a pressure releasing compressing part (5); the pressure releasing spring (2) is sleeved on the pressure releasing compressing part (5) and contacts with the pressure releasing top rod (4) elastically; the valve body (1) is also provided with a middle pressure releasing valve (6), the pipe chamber of which is provided with the pressure releasing top rod (4) and the pressure releasing compressing part (5); and the through pipeline (3) of the valve body (1) is communicated with the pipe chamber of the middle pressure releasing valve (6). The pressure balance valve can replace an external-connection expansion tank type on the loop of circulation medium, reduce the production cost and obtain excellent economical benefits due to simple structure, small volume and high reliability.
Description
Technical field
The present invention relates to a kind of pressure valve, especially relate to a kind of equilibrated valve that is used for the separated type solar water heating system.
Background technique
Along with popularizing of solar water heater, the user is more and more higher to the functional requirement of water heater.The solar water container of prior art, its structure generally comprises shell, turnover water pipe, heat exchanger and inner bag.This water tank also can carry out medium circulation by the heat exchanger in the water tank except adopting electric heating, thereby improves the heat exchange effect of water tank.Circulatory mediator often forms the loop by the heat exchanger of external heat collector and solar water heater, in actual use, because the problem of expanding with heat and contract with cold of circulatory mediator causes the pressure possibility in pipeline or the seal container too high or too low, i.e. the pressure imbalance problem.At this problem, present generally external expansion drum on the pipeline that connects heat collector makes circulatory mediator can carry out pressure and regulates.But the mode of this external expansion drum not only volume ratio is bigger, the cost height, and also reliability is also unsatisfactory.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure, equilibrated valve that is used for the separated type solar water heating system that volume is little.
Technical problem to be solved by this invention is achieved by the following technical solution: it comprises valve body and pressure release spring, one end of described valve body is the gas pipeline of hollow, be provided with pressure release push rod and pressure release compressing member in the other end tube chamber, pressure release compressing member and valve body tube chamber scyewed joint, pressure release spring housing on the pressure release compressing member and with pressure release push rod Elastic Contact; Decompression valves in the middle of also being provided with one on the valve body, be provided with pressure release push rod and pressure release compressing member in the tube chamber of middle Decompression valves, pressure release compressing member and middle Decompression valves tube chamber scyewed joint, the pressure release spring housing on the pressure release compressing member and with pressure release push rod Elastic Contact, the gas pipeline of valve body is connected with middle Decompression valves tube chamber.
Be equipped with the pressure release packing ring on the pressure release push rod in valve body of the present invention and the middle Decompression valves.
The said structure that the present invention adopts because simple in structure, volume is little, the reliability height can substitute external expansion drum mode on the loop of circulatory mediator, reduced cost of production, obtains good economic benefit.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Figure 1 shows that structural representation of the present invention
Figure 2 shows that the A-A cut-away view among Fig. 1
Figure 3 shows that the B-B cut-away view among Fig. 1
Embodiment
By Fig. 1, Fig. 2, Fig. 3 as can be known, this equilibrated valve that is used for the separated type solar water heating system comprises valve body 1 and pressure release spring 2, one end of described valve body 1 is the gas pipeline 3 of hollow, be provided with pressure release push rod 4 and pressure release compressing member 5 in the other end tube chamber, pressure release compressing member 5 and valve body 1 tube chamber scyewed joint, pressure release spring 2 be enclosed within on the pressure release compressing member 5 and with pressure release push rod 4 Elastic Contact; Decompression valves 6 in the middle of also being provided with one on the valve body 1, be provided with pressure release push rod 4 and pressure release compressing member 5 in the tube chamber of middle Decompression valves 6, pressure release compressing member 5 and middle Decompression valves 6 tube chamber scyewed joint, pressure release spring 2 be enclosed within on the pressure release compressing member 5 and with pressure release push rod 4 Elastic Contact, the gas pipeline 3 of valve body 1 is connected with middle Decompression valves 6 tube chambers.Pressure release push rod 4 can be made axially reciprocating under the effect of gas pressure and spring.Middle Decompression valves 6 can with valve body 1 scyewed joint.One end of valve body 1 can be provided with screw thread, with convenient fastening being installed on the circulatory mediator loop.Be equipped with pressure release packing ring 7 on the pressure release push rod 4 in described valve body 1 and the middle Decompression valves 6, pressure release packing ring 7 can be made of rubber, to increase tightness.Overpressure when the circulatory mediator loop, during greater than spring force and ambient pressure sum, the pressure release push rod 4 in the middle Decompression valves 6 closely contacts with middle Decompression valves 6, Decompression valves 6 cuts out promptly, and valve body 1 intraluminal pressure release push rod 4 is open, and promptly valve body is open-minded, realizes the pressure release function; Hypotony when the circulatory mediator loop, during still less than ambient pressure, valve body 1 intraluminal pressure release push rod 4 closely contacts with valve body 1 with the spring force sum, be that valve body is closed, and the pressure release push rod 4 in the middle Decompression valves 6 is pushed open by ambient pressure, and promptly middle Decompression valves is open-minded, realizes function of increasing pressure; Like this, just can set critical pressure value, to realize pressure balance by the size of Regulation spring power.
Claims (2)
1, a kind of equilibrated valve that is used for the separated type solar water heating system, comprise valve body and pressure release spring, it is characterized in that: an end of described valve body is the gas pipeline of hollow, be provided with pressure release push rod and pressure release compressing member in the other end tube chamber, pressure release compressing member and valve body tube chamber scyewed joint, pressure release spring housing on the pressure release compressing member and with pressure release push rod Elastic Contact; Decompression valves in the middle of also being provided with one on the valve body, be provided with pressure release push rod and pressure release compressing member in the tube chamber of middle Decompression valves, pressure release compressing member and middle Decompression valves tube chamber scyewed joint, the pressure release spring housing on the pressure release compressing member and with pressure release push rod Elastic Contact, the gas pipeline of valve body is connected with middle Decompression valves tube chamber.
