Abstract
A energy-saving and anechoic check valve comprises a valve body (1), a valve base (9), a valve rod (4) with one end a valve clack (6) which is provided with a gland bush (7) and a leading bogie (8), and the other end sliding passing through a bracket (2). A spring (3) is arranged between the valve clack and the bracket. The utility model is characterized in that the valve body is provided with a pressure gauge component (19) which is communicated with a pressure tap (20) which is communicated with the inner cavity of the valve body. The utility model can measure out the static pressure value of the medium in the valve by the pressure tap on the valve body under different working conditions and the pressure valve can be shown on the pressure gauge, thereby providing effective pressure parameter for water supply network.
Description
Technical field
The utility model belongs to a kind of energy-saving damping safety check.
Background technique
That existing energy-saving damping safety check has is energy-conservation, the advantage such as effective of eliminating the noise, but its deficiency is the static pressure that can not show medium in the valve body in real time.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of energy-saving damping safety check that can show medium static pressure in the valve body under various working conditions in real time is provided.
The technological scheme that addresses the above problem is (referring to implementing illustration): the utility model comprises valve body (1), be provided with valve seat (9) in the valve body, valve rod (4), valve rod one end is the flap (6) that sealing gasket (7) and leading truck (8) are housed, the other end is slidingly matched and passes support (2), spring (3) is housed between flap and the support, it is characterized in that: pressure gauge assembly (19) is housed on the described valve body, and the pressure gauge assembly is installed on the pressure tap (20) that is communicated with body cavity.
The utility model can be measured the medium static pressure in the valve body by the pressure tap on the valve body at any time and show on pressure gauge under different working conditions, for water supply network provides effective pressure parameter.

Specific embodiments
Flow channels in this routine valve body 1 is divided into water-inlet cavity 10 and water chamber 18 by valve seat 9, be provided with support 2 in the water chamber, valve rod 4 one ends are slidingly matched and pass support 2, the other end is equipped with the flap 6 that the nut 5 that is locked is fixed, flap is provided with sealing gasket 7 and leading truck 8, be provided with spring 3 between flap 6 and the support 2, flap flexibly is pressed on the valve seat, the sealing gasket 7 on the flap constitutes sealing pair with valve seat 9.Under the effect of spring 3, keep enough specific pressures, prevent that downstream water from flowing backwards, when leading truck downside water-inlet cavity 10 provided press water, spring 3 was subjected to force compresses, and valve rod 4 drives flap 6, sealing gasket 7 and leading truck 8 and rises simultaneously, safety check is opened overcurrent, pressure of supply water is during less than length of spring compressed elastic force, flap closed valve seat, closure of check ring cutout.
This example has pressure tap 20 on the valve wall of water chamber 18, pressure gauge assembly 19 is housed on the valve body, is communicated with pressure tap 20.
This routine water chamber 18 also is provided with a bypass drain valve 11, the bypass drain valve is provided with drain valve seat 12, drain valve stem 13, handwheel 17 passes setting sleeve 15 and is connected with drain valve stem, seal by O RunddichtringO 14 between the handwheel body of rod and the setting sleeve, bypass drain valve water outlet can communicate with upstream, also can communicate with other pipeline.
The effect of this routine set bypass drain valve 11 is: when this valve cuts out, in the time of will carrying out various construction to the downstream pipe network, can open the bypass drain valve, the water that accumulates in the pipe network of downstream is discharged back in the upstream tube or does other use, not only save the water source but also can prevent to accumulate water logging and soaked the existing field boundary in downstream, provide convenience for construction, close the bypass drain valve, this safety check can recover proper functioning.The situation that the downstream pipe network accumulates water can show by pressure gauge.
Claims (2)
1, energy-saving damping safety check, comprise valve body (1), be provided with valve seat (9) in the valve body, valve rod (4), valve rod one end is the flap (6) that sealing gasket (7) and leading truck (8) are housed, and the other end passes support (2) with being slidingly matched, and spring (3) is housed between flap and the support, it is characterized in that: pressure gauge assembly (19) is housed on the described valve body, and the pressure gauge assembly is installed on the pressure tap (20) that is communicated with body cavity.
2, energy-saving damping safety check according to claim 1 is characterized in that: the flow channels in the described valve body (1) is divided into water-inlet cavity (10) and water chamber (18) by valve seat (9), and water chamber (18) is provided with a bypass drain valve (11).
