Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a two-way stagnant water valve of opening. Referring to fig. 1 and 2, the two-way water stop valve includes a gate frame 1, a gate 2 is slidably connected to the gate frame 1 along a vertical direction, a screw rod lifter 3 is installed at the top of the gate frame 1, and the bottom end of a screw rod of the screw rod lifter 3 is connected to the gate 2, so that the gate 2 is moved up and down. The equal fixedly connected with stagnant water rubber strip 4 in both sides of gate 2, stagnant water rubber strip 4 lie in gate 2 lateral wall all around and laminating gate frame 1 sets up to this makes water pressure no matter which one side at gate 2, and the homoenergetic makes gate 2 conflict gate frame 1 through stagnant water rubber strip 4 and plays the effect that compresses tightly sealed, reduces gate 2 and appears the possibility of leaking.

Referring to fig. 2, gate 2 is at the in-process that reciprocates, because gate 2 both sides all fixedly connected with stagnant water rubber strip 4, when reciprocating, stagnant water rubber strip 4 and gate frame 1's resistance grow make gate 2 reciprocate the difficulty, and stagnant water rubber strip 4 also can aggravate wearing and tearing to reduce gate 2's stagnant water effect. Consequently set up pressure relief structure 5 on gate 2, water pressure to gate 2's influence when can reducing gate 2 and reciprocate makes gate 2 press the pressure on stagnant water rubber strip 4 and reduces, under the condition that does not influence the stagnant water valve use for gate 2 receives the resistance when reciprocating and reduces, reduces the wearing and tearing condition of stagnant water rubber strip 4 simultaneously.

Referring to fig. 2, an upper communicating port 61 and a lower communicating port 62 are sequentially formed in the gate 2 from top to bottom along the vertical direction, the upper communicating port 61 and the lower communicating port 62 all penetrate through the gate 2, a communicating groove 63 is formed in the gate 2 along the vertical direction, one end of the communicating groove 63 is communicated with the upper communicating port 61, and the other end of the communicating groove 63 is communicated with the lower communicating port 62. Pressure relief structure 5 includes pressure release board 51 and stagnant water board 52, and pressure release board 51 is provided with two and is located the inside both ends of communicating opening 62 down respectively, and pressure release board 51 shelters from the cross-section setting of communicating opening 62 down, and pressure release board 51's bottom is rotated with communicating opening 62 down and is connected, and stagnant water board 52 passes through connecting rod 521 fixed connection on gate frame 1, the one end and the stagnant water board 52 fixed connection of connecting rod 521, the other end and the gate frame 1 fixed connection of connecting rod 521. The two water stop plates 52 are arranged at two ends of the upper communication port 61 respectively, and the two water stop plates 52 are arranged to shield the upper communication port 61.

Referring to fig. 2 and 3, in order to limit the pressure relief plate 51, so that the pressure relief plate 51 can only rotate towards the other pressure relief plate 51, a limiting strip 7 is fixedly connected to the top side wall of the lower communication port 62, and two limiting strips 7 are arranged on two opposite sides of the two pressure relief plates 51. The pressure relief plate 51 on the side with the larger water pressure overturns through the water pressure and pushes against the other pressure relief plate 51, so that the water flow on the side with the larger water pressure on the gate 2 can flow into the upper communication port 61 through the communication groove 63 and flow out of the upper communication port 61, and the purpose of pressure relief is achieved.

Referring to fig. 2, in order to improve the sealing effect of the water stop plate 52 on the gate 2, the water stop plate 52 is provided with a section larger than that of the upper communication port 61, a seal ring 81 is fixedly connected to the side wall of the water stop plate 52 facing the gate 2, and the seal ring 81 is provided in contact with the gate 2.

Referring to fig. 2, in order to improve the structural stability of the water stop plate 52, a guide block 82 is fixedly connected to a side wall of the water stop plate 52 facing the gate 2, a guide groove 83 is formed in the gate 2 along the vertical direction, and the guide block 82 is located in the guide groove 83 and is in sliding fit with the guide groove 83. In order to make the water stop plate 52 move more smoothly relative to the gate 2, two guide blocks 82 are symmetrically arranged on the water stop plate 52 at two sides of the movement direction of the water stop plate 52 relative to the gate 2, and in order to make the sealing ring 81 on the water stop plate 52 better fit on the gate 2, the cross sections of the guide blocks 82 and the guide grooves 83 are both in dovetail type arrangement, so that the guide blocks 82 are not easy to be separated from the guide grooves 83.

Referring to fig. 2 and 3, in order to ensure the fluency of the communication groove 63 and reduce the possibility of the communication groove 63 being blocked, both ends of the lower communication port 62 are provided with a sinking groove 91, and an intercepting filter screen 92 is arranged in the sinking groove 91, so that impurities in water can be filtered. In order to facilitate the workers to clean the intercepting screen 92 regularly, the intercepting screen 92 and the gate 2 are connected in a bolt bolting mode in this embodiment.

The implementation principle of two-way stagnant water valve of this application embodiment does: gate 2 is at the in-process that descends, the in-process that descends is not sheltered from to the sealing plate 52 this moment, the rivers of the great one side of water pressure are to pressure release board 51 application of force on gate 2, the pressure release board 51 upset that makes the great one side of water pressure is pressed on the pressure release board 51 of the less one side of water pressure, thereby open down intercommunication mouth 62, rivers are along intercommunication groove 63 upflow realization pressure release, thereby reduce the resistance that receives when gate 2 reciprocates, when gate 2 removes the bottom, sealing plate 52 shelters from last intercommunication mouth 61, the realization is to last intercommunication mouth 61's closure, no matter which one side at gate 2 is pressed to this moment water pressure, the homoenergetic makes gate 2 play the effect that compresses tightly sealed through sealing rubber strip 4 conflict gate door frame 1. The staff regularly will intercept filter screen 92 and dismantle and wash or change to guarantee the smoothness nature of intercommunication groove 63, make gate 2 keep better pressure release effect all the time.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
