Abstract
The utility model relates to a constant pressure valve which is suitable for a gas water heater, a gas wall hanging furnace, a heat pump water heater, a solar water heater, and the like. The gas water heater comprises a press cover, a valve body, a valve core, a valve sleeve, a spring and a regulation cover, wherein the spring is placed in a cavity formed by the valve sleeve, the valve body and the regulation cover; two ends of the spring are respectively resisted against the end part of the valve core and the end part of the inner cavity of the regulation cover; and a water inlet, a water outlet and a water flow channel connecting the water inlet and the water outlet are arranged on the valve body. When the pressure of the outlet water of the gas water heater is over-high, the water pressure drives the valve core to move and compresses the spring so as to decrease the water inlet of the water channel of the valve body, reduce the volume of the outlet water from the water heater, efficiently limit and decrease the pressure and achieve high degree of automation. The utility model efficiently solves the problems that the volume of the outlet water and the water temperature are unstable caused by the suddenly increased water pressure of the gas water heater.
Description
Technical field: the utility model relates to a kind of constant pressure valve, and it is applicable to gas water-heater, burnt gas wall hanging furnace, heat pump water heater, solar water heater etc.
Background technique: in the prior art, constant pressure valve, not good enough as the constant pressure valve voltage regulation result of gas water-heater, under the unsettled situation of the intake pressure of water valve, after the constant pressure valve voltage stabilizing, the discharge pressure of water valve still can produce fluctuation, and when especially the intake pressure of water valve increased suddenly, the discharge pressure of water valve also increased thereupon suddenly, and water-outlet quantity is increased, water temperature reduces, and causes to have the hydraulic pressure instability, and then influence normally defective such as use of user.For overcoming these defectives, the constant pressure valve of gas water-heater is improved.
Summary of the invention: technical problem to be solved in the utility model is that a kind of constant pressure valve will be provided, and it can stablize hydraulic pressure effectively, ensures user's normal use.
The technological scheme that its technical problem that solves the utility model adopts is: it comprises gland, valve body, spool, valve pocket, spring, adjustable cap, valve pocket places in the chamber of valve body, spool and spring place respectively in the chamber of valve pocket, two ends of valve body is by gland and adjustable cap sealing, and valve body is provided with the flow channel of water intake, water outlet, connection water intake and water outlet.
The setting of staggering of described water intake and water outlet, described flow channel is kink shape.
The stepped bending of described flow channel.
The curved bending of described flow channel.
Described flow channel is the oblique line bending.
The coaxial successively setting of described gland, spool, valve pocket, spring, adjustable cap.
Described spool is provided with the seal spool groove, gland is provided with the gland seal groove, is with valve core seal ring in the seal spool groove, is with gland ring in the gland seal groove, spool is by the bore seal of valve core seal ring and valve pocket, and gland is threaded with valve body and seals by gland ring.
Described valve body is provided with the first valve seal groove and the second valve seal groove, be with first valve seals, second valve seals respectively on the first valve seal groove, the second valve seal groove, valve pocket is by the bore seal of first valve seals, second valve seals and valve body.
Described spring places in the chamber that is surrounded by valve pocket, valve body, adjustable cap, and both ends of the spring withstands the end of spool and the inner chamber end of adjustable cap respectively.
The utility model is compared the beneficial effect that is produced with background technique:
The setting because the water intake of the utility model employing valve and water outlet stagger, be provided with the structure of the flow channel that is communicated with water channel water intake and water outlet in the spool, when the discharge pressure of gas water-heater is excessive, the hydraulic drives spool moves, pressure spring, thereby dwindle the water intake of valve body water channel, reduce the water-outlet quantity of water heater, thereby effectively play the pressure limiting decompression.So it can stablize hydraulic pressure effectively, ensure user's normal use, the automaticity height.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure explosive view of Fig. 1.
Fig. 3 is the structural representation of valve body 2 among Fig. 1.
Fig. 4 is the structural representation of spool 3 among Fig. 1.
Fig. 5 is the structural representation of valve pocket 4 among Fig. 1.
Embodiment: shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, present embodiment comprises gland 1, valve body 2, spool 3, valve pocket 4, spring 5, adjustable cap 6.
Spool 3 is provided with seal spool groove 55, gland 1 is provided with gland seal groove 58, be with valve core seal ring 51 in the seal spool groove 55, be with gland ring 54 in the gland seal groove 58, spool 3 is by the bore seal of valve core seal ring 51 with valve pocket 4, and gland 1 is threaded with valve body 2 and seals by gland ring 54.
Wearing and tearing valve pocket when the setting of valve pocket 4 can avoid spool 3 to move helps changing the Component of constant pressure valve and reduces maintenance cost.
The utility model spool 3, flow channel 31 also can adopt the design of curve-like bending or the design of oblique line shape bending except can adopting stepped shaft bending design.
The utility model limits water-flowing amount by the water inlet section area that turns down water intake 21, realizes the hydraulic pressure regulation and control.Specifically be that tap water passes through water intake 21, flow channel 31, water outlet 22 outflows, during current process flow channel 31, hydraulic action is at the inwall of flow channel 31, make spool 3 pressure springs 5, spool 3 is to adjustable cap 6 one side shiftings, and until pressure and the spring force balance of flow action at flow channel 31 inwalls, spool 3 parts are covered water intake 21, the passage section of water intake 21 is reduced, the restriction water-flowing amount.The maximum value of the discharge pressure of the utility model constant pressure valve is 3kg/cm
2, the user can be by rotating the maximum value that adjustable cap 6 pressure springs 5 are regulated the constant pressure valve discharge pressure.
The utility model can play pressure control pressure limiting effect effectively, and the automaticity height can be applicable to the water control system of hot water facilities such as gas water-heater.Valve body 2 in the utility model, spool 3, valve pocket 4 can be metal or plastics, also can be metal and plastics composite structure.
